  - JBoss 3.2.2 security
    Hello,
    
    I'm developing EJB based system on JBoss. The system consists of
    two parts: the set of EJB's, mainly Entity Beans which are interfaces
    to DB and servlet which is used as user interface. As the interface to
    entity beans i'm using statefull session bean. Every call from servlet
    have to pass throught it.
    To authenticate users I'm using DatabaseServerLoginModule. Users are
    able to login, but then they try again to execute eny method from
    session bean the server throws exception
    Authentication exception, principal=null
    What am i doing wrong ?? Should I store the users principal or
    it is stored in session context ?
    
    Cheers,

  - java & CGII am a programming student attempting a quoting system (similar to what
    geico does) for my job. I've written a program that is executable from
    the command prompt that returns the expected values, but I need it to
    work with a webpage.
    
    I want the user to be able to input data, the program process it, and
    then display the results. I've found code that uses "POST" to get the
    data to a program, but how does the program process it and how do I get
    it back into another web page? I've searched the web but I'm having
    difficulty finding answers.
    
    Thanks in advance to anyone who can help.

    I would like to know more about JAVA and its applications in the real
    world.
    Where can I find jobs after studyig it??? From where will I get

  - Is it possible to design Audio CD player by using Java only?Never tried it myself, but have you looked at java media api. i am thinking
    if reading file from the cd in a normal way (binary stream) and then
    feeding it to media api can do the job....!!!
    Good luck anyways :-)

  - Capture keystrokeHi,
    
    I have a command line java program and I am trying to capture a keypress
    from the user to say pause or stop the program. The only way I can get
    this to work at the moment is to read in a key but the program waits for
    the user to press return. I don't want this. I want to read the keypress
    asynchronously without the user hitting return.
    
    Anybody give me some pointers to how to do this?
    
    Thanks in advance

  - Java Applet in Mac FireFox sets multiple DIFFERENT cookiesI've been fighting with this one for a couple days. I'm getting two
    (different) cookie headers being set.
    
    Quick Background:
    - Using a TurboGears web application.
    - Embedding an Applet to assist in file uploads (JUpload).
    - Applet uploads the files and sends the data to a secure URL.
    - A session ID preserves the user's login information so they don't
    get a 403 or have to login again.
    - Works totally fine in everything EXCEPT FireFox on a Mac (Safari
    works fine, as well as FireFox in Windows)
    
    Using Ethereal to look at the HTTP header, there are two "Cookies"
    values being set. The one that I set, and some other random one which
    I have NO idea where it is coming from. As follows:
    
    POST /import/upload HTTP/1.1
    Cookies: tg-visit=2k842fgj237dfkvh232c32hdh3832
    Content-length: 123541
    <blah blah blah other headers>
    Cookies: tg-visit=743jk82hfg94520fng62j8233jfg826
    
    The first tg-visit value (the session id) is correct. The second one
    which is the last header being set, is some other id being set. In
    Safari the tg-visit value is the same on both lines and it works fine.
    Other browsers properly only sets a single line. Firefox on a Mac
    gives me two different values, and I have NO idea why.
    
    Code to follow:
    
    <APPLET CODE="foo.bar.myApplet" ARCHIVE="/static/myApplet.jar"
    WIDTH="450" HEIGHT="320">');
    <PARAM name="type" value="application/x-java-applet;version=1.4" /
    >');
    <PARAM name="scriptable" value="true" />
    <PARAM name="postURL" value="${postUrl}" />
    <PARAM name="redirectURL" value="${redirectUrl}" />
    <PARAM name="tgVisitValue" value="tg-visit=${tgVisitValue}" />
    </APPLET>
    
    I have also tried to use the MAYSCRIPT attribute, but that doesn't
    really help.
    Using TurboGears which fills in the ${tgVisitValue} properly (which
    works fine).
    
    myApplet.java
    
    this.mycookies = this.getParameter("tgVisitValue",
    DEFAULT_COOKIE_STRING);
    if (this.mycookies == DEFAULT_COOKIE_STRING) {
    try
    {
    JSObject window = JSObject.getWindow(this );
    JSObject document =
    (JSObject)window.getMember( "document" );
    
    String cookies =
    (String)window.eval("self.document.cookie");
    if (cookies.equals("undefined")) // we're IE
    cookies = (String)document.getMember("cookie");
    
    // NAOMI
    // get all the unexpired cookies
    // this.mycookies = (String) document.getMember( "cookie" );
    
    }
    catch ( Exception e )
    {
    this.mycookies = "nocookie=0";
    }
    }
    
    This grabs the cookie value properly, so I don't think there are any
    problems there. The code that does all the HTTP magic is here:
    
    try{
    String boundary = "-----------------------------" +
    getRandomString();
    
    url = new URL(uploadURL);
    // Setting up the connection for upload.
    urlConn = url.openConnection();
    urlConn.setRequestProperty("Cookie", this.mycookies);
    urlConn.setDoInput (true);
    urlConn.setDoOutput (true);
    urlConn.setUseCaches (false);
    urlConn.setRequestProperty("Content-length", ""+totalFilesLength);
    urlConn.setRequestProperty("Content-Type",
    "multipart/form-data; boundary=" +
    boundary.substring(2,
    boundary.length()));
    
    String CRLF = "\r\n";
    
    urlConn.connect();
    
    // Retrieve OutputStream For upload (Post).
    dOut = new DataOutputStream(urlConn.getOutputStream());
    
    // Actual Uploading part.
    StringBuffer sb;
    File f;
    uploadedLength = 0;
    for(int i=0; i < aTotalFiles.length && !stop; i++){
    f = aTotalFiles[i];
    sb = new StringBuffer();
    // Line 1.
    sb.append(boundary);sb.append(CRLF);
    // Line 2.
    sb.append("Content-Disposition: form-data; name=
    \"File");sb.append(i);
    sb.append("\"; filename=\"");sb.append(f.toString());
    sb.append("\"");sb.append(CRLF);
    // Line 3 & Empty Line 4.
    sb.append("Content-Type: application/octet-stream");
    sb.append("Content-Length: " + f.length());
    sb.append(CRLF);sb.append(CRLF);
    
    dOut.writeBytes(sb.toString());
    uploadFileStream(f,dOut);
    dOut.writeBytes(CRLF);
    }
    
    // Telling the Server we have Finished.
    dOut.writeBytes(boundary);
    dOut.writeBytes("--");
    dOut.writeBytes(CRLF);
    dOut.flush ();
    
    if(!stop) progress.setString("File(s) uploaded. Wait for server
    response!");
    bInp = new BufferedReader(new
    InputStreamReader(urlConn.getInputStream ()));
    
    Any ideas?

    Below are the sample code i have written for searching word honda,
    1990 and imran.I also want to save word honda in static string name
    classtring. For first line i use this java code to save word honda in
    classtring and its working well. I have a problem to save second line
    1990 and imran.
    The technique i use is searching until "=" and save word after "=".Can
    anyone give the idea and java code.

  - How to compute a regex match against an object's parameter by name?Consider that you want to do a regex match on the contents of an
    attribute of that object. Say, for example, the contents of:
    
    SomeObjectInstance.x
    
    All is well unless you don't know ahead of time that "x" is the
    attribute that the user will search against. Suppose that the object
    can have any attribute name, and even all those possibilities aren't
    known at compile time. The user can/will select this attribute, as well
    as the regex pattern.
    
    So the trick is how to apply the match against "x" in this case with
    only "x" as a string passed to the method?
    
    // this doesn't work!
    public boolean isRegexMatch(String p, String m, SomeObject o, String
    attribute){
    Pattern pat = Pattern.compile(p);
    Matcher mat = pat.matcher(o."attribute"); <--- doesn't work, obviously
    return (mat.find());
    }
    
    The above would be nice, but as expected-it doesn't work.
    
    So the question is, how to make the method functional without knowing
    what it will be passed for "attribute"?
    
    TIA!

  - how to get the content from an URL?Hi people,
    
    I have write some code that outputs the content of an URL in
    System.out,
    which is really trivial using the following code:
    
    URL url=new URL("http://www.some-url.com");
    URLConnection c=url.openConnection();
    BufferedReader is=new BufferedReader(new
    InputStreamReader(c.getInputStream()));
    
    String line;
    while ((line=is.readLine())!=null) {
    System.out.println("line: "+line);
    }
    
    But, some URLs have javascript code embedded that redirects the page
    or refills
    it in some way when it's automatically run by the browser. I want to
    have the HTML code after executing that javascript code, exactly as
    you can get it from your internet browser's "view source-code", not as
    I'am getting it by now.
    
    The cuestion is...
    
    there is ANY workaround to this issue? some way to run javascripted
    pages from
    java? some way to deliver it to a web browser, or something nicer?
    
    thanks to everyone,

  - Reading an array of byte with special delimiter....help me!!Hi guys,
    i've developed a java application that has in input a txt file with a
    standard format
    
    string string string
    string double double
    string double double
    
    and stores it into an array of byte with a fixed format,
    that is
    byte(whitespace)byte(whitespace)byte(;)byte(whitespace)byte(whitespace)byte(;)byte(whitespace)byte(whitespace)byte(;)
    
    that mean introducing byte whitespace value and byte ; value to
    separate different columns and different rows.
    Now i have to develop inverse routine,that has to read the array of
    byte and rebuild its original format.
    Can you help me with some idea ord code?
    I'm inexepert...please help me with clear suggest...
    I post you my routine that converts txt file into an array of byte
    P.S.In my txt file number of columns and rows change for each file,what
    is standard is a firtst headline that is an array of string and others
    row with the same format string array of doubles....
    
    [code]public byte[] getBytes(){
    byte middlerow=' ';
    byte endrow=';';
    Vector temp=new Vector(10000000);
    int i=0;
    String g=null;

    // memorizza in byte un elemento del vettore alla volta
    for( Byte aByte : bytes ) {
    temp.addElement( aByte );
    
    }
    
    temp.addElement( Byte.valueOf( middlerow ) );
    
    i++;
    }
    temp.addElement(Byte.valueOf(endrow));
    System.out.println("Intestazione convertita in byte");
    
    for(int l=0;l<rows.size()-1;l++){
    r=(Riga)rows.get(l);
    g=r.getgeneid();

  - Storing and parsing variable length stringsHi folks...
    
    I have an application which needs to store variable-length strings (up
    to 24 characters long) that must then be matched according to prefix.
    That is, whenever a prefix is given, the application has to be able to
    retrieve all stored strings that start with this prefix. Conversely,
    the program has to be able to store strings in such a way, so that
    prefix-based retrieving is fast and accurate (i.e., all relative
    strings are located and retrieved). Doing this linearly is obviously
    slow and inefficient.
    
    So, what is the best way of implementing this functionality in J2SE 1.4
    or later? Or, if there is no ready (preprogrammed) way of doing it
    properly in the standard distribution, are you aware of any open source
    implementation (e.g., tree or something similar)?
    
    Thanks,

  - problems with TCPMONHi,
    I'm using axis 1.2-RC3 and eclipse 3.01RC. When i run tcpmon from
    command line
    >java -cp org.apache.axis.utils.tcpmon
    i use the panel for setting me as listener on port 8083 while tomcat is
    on port 8080.
    The problem is that when the client comunicate with server i dont have
    2 SOAP messages but the tcpmon loops infinite on an error message.
    I cant post you the output because tcpmon goes in infinite loop and its
    impossible to copy text.
    However i have set the axis path appropriately and i have added it to
    classpath and classpath to path so i can call tcpmon with java org.....
    I have also the needed jars (expecially) axis.jar included in axis
    server (on tomcat) and imported in eclipse project.
    Thank you in advance!

java-programmer, recognizing java processes How would you recognize a java process (as java process) in runtime
from outside the JVM? (win32)

is there a nicer way than monitorizing DLL loads in order to detect
the jvm.dll/javai.dll load?

The name of the process is almost always "java.exe" or "javaw.exe".

Download jps tool? (certainly works with Java 1.5 on win32)

  - Problem with table nameHi!
    
    I have a problem to access tables in an Informix Database. Table names
    are something like that :
    informix.pv_tvvte
    
    When I try a "SELECT informix.pv_tvvte.numero_vente FROM
    informix.pv_tvvte WHERE informix.pv_tvvte.numero_vente=#value#", (I use
    ibatis and spring) I get a syntax error exception (SQLException "Bad SQL
    Grammar").
    
    If I replace dot with "_" in the name, I get a "Table Not Found" Exception.
    
    How could I escape the dot in the tables names ?

  - compression API available in Java & C++?Apologies if this is slightly off-topic ...
    
    I'm looking for a compression algorithm that works better than gzip
    for small (12 bytes or so) chunks of data. Ideally there would be a
    free implementation for Java and C++ that we could use for commercial
    purposes.
    
    Specifically, we are streaming data from a C++ server to a Java applet
    and would love to use as little bandwidth as possible.
    
    We're not using any form of compression right now, but the belief is
    that gzip works in blocks, so small chunks of data don't get much
    benefit. (Anyone disagree?)

  - Progress bar in JDialogHi all,
    
    I am a new beginner to Java Programming. In my application I am loading
    an xml doc in JFrame, while doc is loading I would like to see a
    progress bar above the J frame.
    
    This is what I did:
    
    I created a modal JDialog with a progress bar, to be able to show the
    dialog above the frame. But if I do that then it freezes the loading of
    the xml doc in my Jframe. In other words, only after I close the
    JDialog I am able to load the document in my JFrame. Hence, the whole
    point of showing a progress bar while loading the document is missed.
    
    How to get over this problem. Can anyone please help.
    
    Any input is greatly appreciated.
    
    Thanks

  - I miss my preprocessor!There's one thing I really used the C/C++ preprocessor for, and that is
    compile-time control of debugging statements.
    
    in it's simplest form:
    ----------------------------------------------
    // comment out this line to disable debugs
    #define DEBUG 1
    
    #ifdef DEBUG
    # define dbg(msg) printf(msg)
    #else
    # define dbg(msg)
    #endif
    
    void main(int argc, char argv[][])
    {
    dbg("Some sorta message\n");
    }
    ----------------------------------------------
    
    This system had evolved to a very powerful mechanism for
    enabling/disabling/removing debug statements from my code. The beauty of it
    is that debugging code can be removed
    entirely from released code, without removing from the source. (I like
    leaving it in the source because it provides a sort of ancillary
    documentation). The only shortcoming was the lack of variable macro
    parameters in C/C++.
    
    The nearest I could come up with in java is:
    ----------------------------------------------
    class xxx
    {
    private static final boolean DEBUG=true; // set to false to turn
    off debugging
    void dbg(String msg)
    {
    if (DEBUG) // this gets optimized out
    System.out.print(msg);
    }
    
    public static void main( String[] args )
    {
    if (DEBUG) dbg("Some sorta message\n");
    }
    } // xxx
    ----------------------------------------------
    While this does seem to work, it relies on the compiler to implicitly
    optimize the code out. Not that I don't trust the compiler, but how can I
    prove it?
    From an aesthetic point of view, the "if (DEBUG)" part seems to clutter up
    the source.
    And it leaves a stub for dbg() in the code.
    
    My point is, what options are available to reproduce the desired mechanism?
    (Don't give me anything from java 1.5/5.0; I can't use it till it is
    officially released, and the major ide manufactures endorse it).

  - but *very* apropos] Future reuse of codeLOL!
    
    I enjoyed reading that...
    
    I think "Nihil Software" was a bit of a giveaway... Maybe some of my posts
    in the 90s inspired the author <G>.
    
    I hasten to add that this is NOT what we were intending to do with Dulcinea.
    
    Natural language interfaces are not SO hard to write (I wrote one for MS-DOS
    that allowed people who didn't like the command line to communicate in
    English.) It was distributed by a computer vendor in North Sydney as an
    incentive to buy machines from him. He paid me $10 for every machine he sold
    with it on...(It was called "IGOR" - Interactive Guide to On-line Running
    <G>.) I did it because someone said it couldn't be done, and wasn't really
    interested in it as a money maker.
    
    He sold several hundred machines with it on, before Windows 3.1 came out and
    blew it all away.... I received mail from people up to 2 years afterwards
    saying how much they liked it. (If they asked IGOR about his life he would
    give them my e-mail address, as well as an amusing tale of how he escaped
    from Frankenstein's lab <G>)
    
    The concept engine would have used a similar Natural Language simulation for
    interaction with the User, but it would have no UNDERSTANDING of what the
    language meant (apart from keywords which it would act upon).
    
    Nowadays of course, there are some very good Natural Language interfaces and
    they are quantum leaps beyond IGOR.
    
    Don't let the fact that a magazine caught you with a hoax, persuade you that
    such software will never be developed.
    
    Thanks for posting it, John.

  - HTML Parser Help PleaseHi
    
    I am using HTMLEditorKit.Parser class to parse a HTML file. However, I have
    found this Swing HTML parser extremely difficult to use.
    
    I am trying to parse a HTML file and extracting specific information from it
    into a table. Consider the snippet of my HTML and the table I like it to
    generate:
    
    HTML source:
    
    <HTML>
    <TITLE></TITLE>
    <BODY>
    <PRE>
    Identifer: ABCDEFG
    </PRE>
    data: 123456
    <PRE>
    </PRE>
    </BODY>
    </HTML>
    
    TABLE:
    
    ABCDEFG 123456
    
    Here is the code I have so far:
    
    import javax.swing.text.*;
    import javax.swing.text.html.*;
    import java.io.*;
    
    public class HTMLParser extends HTMLEditorKit
    {
    public HTMLEditorKit.Parser getParser()
    {
    return super.getParser();
    }
    
    public static void main (String[] args)
    {
    try
    {
    Reader r = new FileReader("html_file.html");
    HTMLEditor.Parser parse = new HTMLParser.getParser()
    HTMLEditorKit.ParserCallback cb =
    {
    public void handleStartTag(HTML.Tag t, MutableAttributeSet
    a, int a)
    {
    if (t==HTML.Tag.PRE)
    {
    //print whats between the pre tag
    }
    }
    public void handleText(char[] data, int pos)
    {
    //print whats between the pre tags
    }
    };
    
    parse.parse(r, cb, true);
    }
    catch (IOException e)
    {
    System.out.println(e);
    }
    }
    }
    
    I would appreciate it very much if someone could solve this problem for me.
    I tried the sun tutortial, but the examples aren't that clear enough for me.
    
    Thanks
    
    ZOCOR

  - Basic FreeBSD Java/Tomcat questionsHello, all=2E I'm an old hand with Java but relatively inexperienced with=
    
    FreeBSD, and I've never run Java there until the last few days=2E I had a=
    
    few things I was wondering about=2E I can't find these things in the
    archives, and don't know where else to look=2E Some of my questions might=
    
    betray my lack of FreeBSD knowledge =2E=2E=2E
    
    My preferences:
    
    1=2E Avoid customization to the extent possible -- I don't really want to=
    
    spend much energy being an admin -- even if my configuration is not
    optimally flexible, or whatever=2E This means I'd prefer to use packages
    from 5=2E4-RELEASE as opposed to ports, etc=2E
    
    2=2E Not to have to build full JDK (with web start, plugins, etc=2E) --
    building minimal took days as it was=2E
    
    3=2E Simplest system possible, fewest installs possible, ease of
    administration/use=2E
    
    Here's what I've done so far:
    
    1=2E Installed FreeBSD 5=2E4-RELEASE (minimal distribution set only)
    
    2=2E Built jdk-minimal-1=2E4=2E2p7 from source on test machine=2E Seemed=
    to go
    fine=2E Created package using pkg=5Fcreate -b =2E=2E=2E
    
    3=2E Installed jdk-minimal-1=2E4=2E2p7 as package=2E java -version works=
    ; haven't
    tried much else, except =2E=2E=2E
    
    4=2E jakarta-tomcat-5=2E0=2E30 as package WITHOUT its dependencies (i=2Ee=
    =2E,
    pkg=5Fadd -r from my own server, which does not have the fonts stuff on it=
    )=2E=20
    Besides emitting the predicatable complaints about missing dependencies,
    the pkg=5Fadd command emits a warning saying the jdk package is required a=
    nd
    I have jdk-minimal=2E
    
    5=2E Tomcat post-install
    cp conf/server-minimal=2Exml=2Esample to conf/server=2Exml
    cp conf/web=2Exml=2Esample to conf/web=2Exml
    chown www conf/*=2Exml
    /usr/local/etc/rc=2Ed/020* start
    
    What happens:
    
    It works, so far as I can tell=2E This means that I've gone to the home
    page, not tested extensively=2E The 'balancer' webapp doesn't initialize
    correctly (fails with NoClassDefFoundError on
    org=2Eapache=2Ecommons=2Edigester=2EDigester) but I'm not too worried abou=
    t that
    since I don't know exactly what it's for and I haven't read any docs yet=2E=
    
    Questions:
    
    1=2E Why does Tomcat depend on all the font stuff=3F Can I safely run wi=
    thout
    it=3F
    
    2=2E Same question with the jdk vs=2E jdk-minimal issue=2E
    
    3=2E What are the limitations of tomcat50ctl=3F I've seen some messages =
    in
    the archives saying I'll need to change my /usr/local/etc/rc=2Ed script if=
    I
    want to do things like command-line arguments to Tomcat, etc=2E
    
    Comments:
    
    I'm really pleased (as I've worked through these issues) about how smart=20=
    
    the packaging system is (e=2Eg=2E, not deleting files if they've been chan=
    ged)=2E
    Not sure to what extent credit is due FreeBSD developers and to what exten=
    t
    credit is due to people on this list, but take whatever you're entitled to=
    =2E
    :)
    
    Special praise for the jdk14 port -- for such a complex build, I'm shocked=
    
    how well it worked for me, particularly since I know very little about mak=
    e=2E

  - java.util.regex - combining paragraphs separated by blank lineI need to write a regular expression to group lines of text separated
    by a blank line.
    
    Ex.
    
    Input:
    line1
    line2
    line3
    
    line 4
    line 5
    
    line 6
    
    I tried turning on the MULTILINE and DOTALL flags and used the
    following pattern:
    (.+?)^$
    
    which is close but prepends a newline to the 2nd and subsequent calls
    to Matcher.find().
    
    The first line of every paragraph is the same, if that helps.
    
    Regex's are cool, but frustrating....

  - The solutions are very OS specific.Hi Mark Thornton,
    
    You wrote,
    " The rough equivalent to an HDC is
    a java.awt.Graphics object,
    extended ( since Java 1.2 ) to java.awt.Graphics2D.
    These are used for drawing to screens, printers
    or into a BufferedImage. "
    
    That's quit impressive,
    But my bank simulation currently requires Excel,
    which precludes Linux.
    
    Also, if I ever moved my simulations to Direct Draw 7,
    or even Direct 3D 9 ( instead of the GDI )
    once again I'd be forced to use C++,
    as DD7's interaction with MS windows is very tricky
    and very OS specific.
    
    For example,
    Windows' taskbar hoards it's mouse messages.
    The taskbar also turns on the system cursor,
    which blocks VRAM-to-VRAM blts.
    The solutions are very OS specific.
    
    Would the bankers pay for that ? I doubt it.

    However, this exeception is NOT thrown when I launched the same application from

    Any advice?

  - queue management with "application failure management"hi,
    
    I am looking for something which looks like the message queue of the IPC
    systemV with java.
    
    my requirements are:
    
    -management of a queue. one application adds data in this queue and
    another gets data from this queue.
    
    -simple : no server like JMS. (btw if you know some JMS implementation
    without a server it could be what I want). could be in a file.
    
    -no data lost if one application crashes. ie if the application which
    gets data from the queue crashes, the other can continue to add data to
    this queue and the processing will continue without losing data once the
    crashed application is restarted.
    
    do somebody know some libs which implements this?
    
    thanks.
