  - url rewriting when the url contains parametersHi,
    I am trying to maintain sessions by doing URL rewrite. Things were
    working fine till the URL did not contain any parameters. The URL that
    I have now is of the form:
    
    http://myurl?id=1&user=null and on doing a sessionID append it becomes
    
    http://myurl?id=1&user=null;jsessionId=xyzw..
    
    Things still get authenticated but now when I try and get the value of
    user I get passed the whole string after user= and not just null.
    What is the right way to append the sessionID? Btw, I am using the URL
    to connect to a servlet from a j2me client.
    
    Thanks,
    Gaurav

  - Username String suggestionI'm doing Java excercises in University. Part of a program I am working on
    requires me to input a both a surname and forename together and have the
    program output the forename name only.
    
    e.g:
    Please enter student's name: Yuriy Ivanov
    Yuriy scored (+ score) which is a (+ grade)
    
    The only way I can think of doing this is to use a String method to output
    everything until it hits a space, does this sound probable?
    Of course, I would need validation incase only a space is entered.
    
    If this sounds like I'm on the right lines please can someone tell me how
    to do that, if not please can someone tell me a better way. I've only know
    of String concatination which is the opposite of what I need.
    
    If there is a way to do this without methods I'd prefer to have that as
    this part of the program isn't meant to include methods or arrays yet.
    
    Thank you in advance.

  - serialVersionUID.. ?Hello ,
    
    I posted this message in the Eclpse group with no responses. I am using
    Eclipse.
    
    I resolved by defining this in my class:
    
    static final long serialVersionUID = 0;
    
    Now, all of a sudden, this is not working and getting error:
    
    Syntax error on token "DETAIL_FOOTER", VariableDeclaratorId expected after
    this token
    
    Happens when I define this class var in applet or interface:
    
    private DETAIL_FOOTER = "# detail footer";
    
    I do not have a clue! Any one have any Ideas?

  - where are file pointer fields?Hello
    
    Where do top level IO classes like InputStream and OutputStream
    store the file pointer? I could not find any fields section in
    the java api docs.
    
    Does java uses some different method or these
    class members are not documented?

  - Capture conversion and containmentHi,
    
    I'm writing a tool that analyses java-code, but I have a problem fully
    understanding the rules defined in JLS3 for containment and their
    combination with capture conversion.
    
    Take the following classes:
    class Box<T> {}
    class ABox<T extends A> {}
    class A {}
    
    Why (because of which rules) is this type-correct code? :
    ABox<? extends A> a1;
    ABox<?> a2;
    a1 = a2;
    
    (And I really mean "a1 = a2" there, not "a2 = a1")
    The extra bounds "? extends A" doesn't really make a difference,
    ABox<? extends A> and ABox<?> are equivalent, because that parameter already
    has a bound A from the definition of ABox. So, informally I understand why
    this code is safe. But my problem is understanding the formal rules by
    which we can derive that, and where those rules are defined.
    
    My attempt at understanding this:
    The constraint for the assignment is:
    capture-of(ABox<?>) <: capture-of(ABox<? extends A>)
    the capture of ABox<? extends A> is ABox<_T>
    where _T is a fresh type variable with upperbounds A.
    the capture of ABox<?> is ABox<_T2>
    where _T2 is another fresh type variable, also with upperbounds A.
    And ABox<_T2> <: ABox<_T> because _T2 <= _T (_T contains _T2). But why?
    
    I see rules for containment defined (4.5.1.1) for wildcards, but not for
    type variables created by capture conversion. While I would actually expect
    that only rules for type variables would be needed, as types are always
    capture converted before you use them. (And this example is chosen so
    that "skipping" this capture conversion step doesn't work.)
    
    Now, intuitively, I would say that one type variable contains another if all
    its upperbounds are a supertype of one of the upperbounds of the other, and
    all its lowerbounds are a subtype of one of the lowerbounds of the other.
    But I'd like to see something like this in writing somewhere, and I can't
    find an answer to this in the Java Language Specification or anywhere else.
    And this intuitive rule doesn't work for Box<ABox<?>>, because the capture
    conversion of that is just Box<ABox<?>> again.
    So I'm quite confused about how this actually works.
    
    I'd appreciate some help, or pointers to more information about this.
    
    Wouter.

  - ANN: New XML Differencing, Updated XML Mapping in Stylus Studio 5.3
    A new update for the Stylus Studio XML IDE adds a new XML Differencing
    Tool, updated visual XML mapping tools and many other features. Download
    a free trial of Stylus Studio 5.3 at:
    http://www.stylusstudio.com/xml_download.html
    
    Highlights of new XML Differencing Tool:
    * Differencing of XML files and folders using a customizable color-coded
    XML tree view
    * Support for one-to-one and many-to-one XML file
    * Step through XML differences node-by-node
    * View differences using "split-screen" and "merged changes" views
    * Expand all changes, or collapse identical XML blocks to simplify the
    display
    * User-configurable XML differencing settings allow you to optionally
    resolve or ignore
    * XML entity references and XML namespaces
    More information at: http://www.stylusstudio.com/xml_differencing.html
    
    Updates to Stylus Studio XML Mapping Tools:
    Stylus Studio's visual XML mapping tools now support new split-screen
    editing mode that simultaneously display fully editable views of both
    the visual XML mapping diagram and the underlying XSLT or XQuery source
    code which implements the visual XML mapping. You can now edit either
    the source code or the visual XML mapping diagram, and see instantly the
    effect their changes have - all without clicking a separate tab or
    opening another editor. The automatic synchronization of both the visual
    mapping diagram and the XSLT or XQuery source code views is the most
    productive mode for developing XML mappings and is a great way to learn
    the intricacies of XSLT and XQuery. More information at:
    http://www.stylusstudio.com/xml_to_xml_mapper.html
    
    Sincerely,

java-programmer, swing - styled document - paragraph attribute Hello,

1) I assign a document style by

style = myDefaultStyledDocument.addStyle("myStyle" , null);
StyleConstants.setAlignment(style, 1); //1 for center
myDefaultStyledDocument.setLogicalStyle(pos, style);

2) Then, I try to read the style :

AttributeSet attributeSet = myDefaultStyledDocument.getAttributes();
Enumeration attrEnum = attributeSet.getAttributeNames();

while ( attrEnum.hasMoreElements() ) {
Object attrObj = attrEnum.nextElement();
System.err.println("attrObj:"+attrObj.getClass());
}

I read only classes of StyleConstants.ResolveAttribute!...
Strange no ?

For all other StyleConstants that's ok !!
Is there something special to do with Alignment ?

  - Detect if Sun plugin is installed (in IE) EVEN if not set as default in plugin?I've looked everywhere and havent found a way to do what I need to do,
    so I'll try posting this:
    
    We have a need to sent users to one of 2 webpages depending on whether
    they are using the MS JVM/1.1 or the Sun plugin/1.2+
    What we did is create a simple applet that checks the java.version
    property and forwards to the appropriate page depending on its value.
    This should work fine except for one case:
    If the user has the plugin installed but it is not set as the default
    for IE, then IE will use the MS JVM when it encounters the applet tag,
    and the user will get the 1.1 page even though they have the plugin
    installed - we don't want that. Other requirements are that we only
    need to support IE and we don't want the user to have to download the
    plugin if they dont have it.
    Can anyone think of anyone to do this? Can I use the OBJECT tag somehow
    for this? Maybe nesting the OBJECT and APPLET tags? Also, if there was
    anyway to detect the installation of the plugin using javascript it
    would help.
    Any ideas?
    Thanks

  - Searching and replacing multiple strings in textSuppose I have a String like:
    
    "The quick brown fox jumped over the lazy dog's back."
    
    Suppose I wanted to make the following multiple replacements in the
    String:
    
    "quick" -> "slow"
    "brown" -> "red"
    "jump" -> "walk"
    "over" -> "under"
    "back" -> "stomach"
    
    After making the replacements, the String becomes:
    
    "The slow red fox walked under the lazy dog's stomach."
    
    It would be easy to just scan the string N times if we're replacing N
    words but I'd like a way that scans the string only once regardless of
    how many words we're replacing. I'm sure tons of programmers have had
    need for this and I'm wondering if there's already some existing code
    on the net for it.
    
    If not, then what are the best data structures and classes to use for
    this? For example, should the collection of words to replace just be a
    String[] and the collection of replacements just be a String[], so
    that e.g. wordsToReplace[i] is replaced by replacement[i], and then
    you do the search and replace algorithm something loosely along the
    idea of:
    
    0. assume an input String, an output StringBuffer
    1. set c = current input text character
    2. if c is the first character of any of the words in wordsToReplace[]
    then
    2a. check if the next input character is the next character of
    any of the words in our input string and so forth....
    if the input word is a match, append the replacement
    to the output StringBuffer.
    otherwise, append the character c from step 1 to the
    StringBuffer and
    go back to step 1. with the input character
    advanced to the next character.
    
    I'm being very sloppy and crude here and only trying to illustrate the
    idea, because actually programming the above function while making
    sure you handle all the out-of-bounds cases, etc., would be tricky and
    time-consuming, and I want to post here for a pre-canned solution or
    something easy I haven't thought of yet before going to all the
    trouble.
    
    Thanks very much for any replies.

  - inner classes and other stuff...from latest oreilly Learning Java, pg 623:
    www.francesdelrio.com/java/TextEntryBox.java (SSCCE)
    
    I have a few questions about this example:
    
    1. a second class gets created (TextEntryBox$1.class) when this is
    compiled, even though there's no inner class here..
    
    2. it seems like a new instantation of ActionListener is being passed
    in a meth arg.....
    ( field.addActionListener(new ActionListener( ) { )
    
    when in fact ActionListener is an interface and as such cannot be
    instantiated, only implemented.. (as far as I know...;)
    
    3. and this ActionListener interface is not implemented anywhere here
    that I can see....;)
    
    could someone pls explain these things that seem contrary to what I have
    read... (i.e., what I THOUGHT I understood... oh brother....)
    thank you...
    
    (PS: also, pls, why do some methods have a ');' after end of method
    declaration?)

  - Who specifies Java? We know that Java is specified by Sun Microsystems, Inc.
    
    On the other hand, a language is specified by its specification
    and in the case of Java this is the JLS. The specification is
    specified or written by its authors. The authors of the JLS are:
    
    http://images.pearsoned-ema.com/jpeg/large/0321246780.jpg
    
    James Gosling, Bill Joy, Guy Steele, and Gilad Bracha.
    
    So then, is Java being specified by James Gosling, Bill Joy,
    Guy Steele, and Gilad Bracha or by Sun Microsystems, Inc.?

  - Tv Need Extra Money for anything ?! Work for Top $ Tv/ I found this on a bulletin board and decided to try it: A little while back, I was browsing through news groups and e-mails, just like you are now, and came across an article similar to this that said you can make thousands of dollars within weeks with only an initial investment of $6.00!! So, I thought, "Yeah right, this must be a scam," but like most of us, I was curious, so I KEPT reading. Anyway, it said that you send $1.00 to each of the six names and addresses stated in the article. You then place your own name and address in the bottom of the list at $6.00, and post the article in at least 200 news groups. (There are thousands) No catch, that was it. So after thinking it over, and talking to a few people first, I thought about trying it. I figured, "What have I got to lose; except six stamps and $6.00 right, right?" Then I invested the measly $6.00.
    
    WELL GUESS WHAT!!!
    Within seven days, I started getting money in the mail!! I was shocked!! I figured it would end soon, but the money just kept coming in. In my first week, I made about $25.00. By the end of the second week I had made a total of more than $1000.00!! In the third week I had more than $10,000.00 and it's still growing!! This is now my fourth week and I have made a total of $42,000.00 and it's still coming rapidly. It's certainly worth $6.00 and six stamps, and I have spent more than that on the lottery without ever winning!!!
    
    Let me tell you how this works and most important, why it works.......... also make sure you print this out NOW, so you can get the information off of it, as you will need it. I promise you that if you follow the directions exactly that you will start making more money than you thought possible by doing something so easy!!
    
    Suggestion: Read this entire message carefully!! (Print it out or download it)
    
    Follow the simple directions and watch the money come in!! It's easy. It's legal. And, your investment is only $6.00 (Plus postage)!!!
    
    IMPORTANT:
    This is not a rip-off, it is decent; it's legal; and it is virtually no risk - it really works!! If all the following instructions are adhered to, you will receive extraordinary dividends.
    
    PLEASE NOTE:
    Please follow the directions EXACTLY, and $50,000 or more can be yours in 20 to 60 days. This program remains successful because of the honesty and integrity of the participants. Please continue its success by carefully adhering to the instructions. You will now become apart of the Mail Order business. You are in the business of developing Mailing Lists. Many large corporations are happy to pay big bucks for quality lists. However, the money made from the mailing lists is secondary to income, which is made from people like you and me asking to be included in that list. Here are the four easy steps to success.
    
    STEP ONE: Get six separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 6 U.S. $1.00 bills and place ONE inside of EACH of the six pieces of paper so the bill will not be seen through the envelope (to prevent thievery). Next, place one paper in each of the six envelopes and seal them. You now should have six sealed envelopes, each with a piece of paper stating the above phrase, your name and address, and a $1.00 bill. What you are doing is creating a service.
    
    THIS IS ABSOLUTELY LEGAL!!!!!
    You are requesting a legitimate service and you are paying for it!! Like most of us I was a little skeptical and little worried about the legal aspects of it all. So I checked it out with the U.S. Post Office (1-800-238-5355) and they confirmed that it is indeed legal!!
    
    Mail the six envelopes to the following addresses:
    
    1) W. Edens
    4829 Bud Ln
    Lexington, KY 40514
    
    2) L.Lessard
    40 Martins Ferry Rd
    Hooksett,NH 03106
    
    3) J. Safian
    6950 W. Forest Presrv. Dr., #115
    Norridge, IL 60706-1324
    
    4) G. Takla
    690 Adelaide Avenue East
    Oshawa, Ontario, L1G 2A8
    
    5) Q. Huda
    1212- 1315 Bough Beeches Blvd.
    Mississauga, Ontario, L4W 4A1
    
    6) T Ryan
    275 Rt 10E Ste 220-301
    Succasunna, NJ 07876
    
    STEP TWO: Now take the #1 name off the list that you see above, move the other names up (six becomes 5, 5 becomes 4, and etc.) and add YOUR NAME as number 6 on the list.
    
    STEP THREE: Change anything you need to but try to keep this article as close to original as possible. Now post your amended article to at least 200 news groups. :
    (I think there are close to 24,000 groups) All you need is 200, but remember, the more you post, the more money you make!! This is perfectly legal!! If you have any doubts, refer to Title 18 Sec. 1302 & 1341 of the Postal Lottery laws. Keep a copy of these steps for yourself and whenever you need money, you can use it again, and again. PLEASE REMEMBER that this program remains successful because of the honesty and integrity of the participants and by their carefully adhering to directions. Look at it this way. If you were of integrity, the program will continue and the money that so many others have received will come your way.
    
    NOTE: You may want to retain every name and address sent to you, either on a computer or hard copy and keep the notes people send you. This VERIFIES that you are truly providing a service. (Also, it might be a good idea to wrap the $1 bill in dark paper to reduce the risk of mail theft). So, as each post is downloaded and the directions carefully followed, all members will be reimbursed for their participation as a List Developer with one dollar each. Your name will move up the list geometrically so that when your name reaches the #1 position you will be receiving thousands of dollars in CASH!!! What an opportunity for only $6.00 ($1.00 for each of the first six people listed above) Send it now, add your own name to the list and you're in business!!!
    
    *****DIRECTIONS FOR HOW TO POST TO NEWS GROUPS!!!*****
    
    STEP ONE: You do not need to re-type this entire letter to do your own posting. Simply put your cursor at the beginning of this letter and drag your cursor to the bottom of this document, and select 'copy' from the edit menu. This will copy the entire letter into the computer's memory.
    
    STEP TWO: Open a blank 'notepad' file and place your cursor at the top of the blank page. From the 'edit' menu select 'paste'. This will paste a copy of the letter into the notepad so that you will add your name to the list.
    
    STEP THREE: Save your new notepad file as a text file. If you want to do your posting in different settings, you'll always have this file to go back to.
    
    STEP FOUR: You can use a program like "postXpert" to post to all the newsgroups at once. You can find this program at <http://www.download.com>. If you don't understand how it works you can email me at: mailto:email***@***.com (this is only when my name is in the list, so send a copy of my address as well. put this in the header: make millions very easy + my full name)
    
    Use Netscape or Internet Explorer and try searching for various new groups (on- line forums, message boards, chat sites, discussions.)
    
    STEP FIVE: Visit message boards and post this article as a new message by highlighting the text of this letter and selecting paste from the edit menu. Fill in the subject, this will be the header that everyone sees as they scroll through the list of postings in a particular group, click the post message button. You're done.
    
    Congratulations!!!!!!
    
    THAT'S IT!! All you have to do, and It Really works!!!
    
    Best Wishes

    solve it, since i'm not adept at using threads and i think that's
    where the problem is. :)
    
    The source for ByteHolder and RemoteByteHolder is included below. A
    server is run, making a ByteHolder, BH, available via RMI.
    
    Client A obtains the reference to BH, and passes this on to its
    FooOutputStream, which extends OutputStream and implements the
    write(int b) method by calling putByte(b) on BH.
    
    Client B also gets BH, passes this to FooInputStream, which extends
    InputStream and implements read() by calling getByte() on BH.
    
    What i did to test was:
    - run the server
    - client A wraps the FooOutputStream in a PrintWriter, and
    println("foo") is called on it
    - client B wraps FooInputStream in a InputStreamReader, which is
    then wrapped in a BufferedReader, and readLine() is called on that
    
    The data then goes, one byte at the time, from client A to client B.
    Client A stops running, but Client B just sorta hangs around... in a
    deadlock i presume. I can make it return and print out the read line
    by doing one of two things:
    - kill the server
    - manually send a -1 to client B
    
    When i've used streams before, i didn't have to send a -1 in order to
    get the reading side to get on with it - it just happened magically. I
    also don't understand why killing the server make things better...
    
    Can anyone explain this or, as an alternative, suggest a better way to
    exchange bytes via RMI. I just really wanted to make streams work. :)
    
    Oh, another thing. To make the server available, i've made it Runnable
    and in the run i have a while(true) loop, that makes the thread sleep
    for a chunk of time. Maybe that is a problem, too?

  - Trap and write out error to fileI am using the following borrowed code to run unix commands.
    Occasionally it returns 3, apparently without actually running the
    command and I do not know why.
    
    I would like to get more info on the error and write it to a file.
    
    As I am not a java programmer can someone help me amend the code to
    write the error details of the t object to a file?
    
    Thanks in advance.
    
    Runtime rt = Runtime.getRuntime();
    Process p = rt.exec(Command);
    try {
    rc = p.waitFor();
    } catch (InterruptedException intexc) { rc = 2; }
    
    rt.gc();
    } catch (Throwable t) { rc = 3; }

  - Memory issueHi All,
    
    I have a problem with memory when I use a connection to a database. I have
    also posted the question in the database group but as I suspect that it has
    to do with garbage collection I also post the question here.
    
    I have a problem with memory using SQLserver on a server running WIN2K
    Advanced Server with 2 GB! of internal memory. We limmited the SQLserver
    memory to 1 GB and 512 MB for JVM (version 1.4.2_01). The OutOfMemory error
    is always at the same place in the jdbc driver as shown below.
    
    java.lang.OutOfMemoryError
    at com.microsoft.util.UtilPagedTempBuffer.compressBlockList(Unknown Source)
    at com.microsoft.util.UtilPagedTempBuffer.getBlock(Unknown Source)
    at com.microsoft.util.UtilPagedTempBuffer.write(Unknown Source)
    at com.microsoft.util.UtilPagedTempBuffer.write(Unknown Source)
    at com.microsoft.util.UtilByteArrayDataProvider.receive(Unknown Source)
    at com.microsoft.util.UtilByteOrderedDataReader.receive(Unknown Source)
    at com.microsoft.jdbc.sqlserver.tds.TDSRPCRequest.submitRequest(Unknown
    Source)
    at com.microsoft.jdbc.sqlserver.tds.TDSCursorRequest.openCursor(Unknown
    Source)

    Source)
    .............................................. Truncated from here
    .................................................
    
    If I run (using same database & JVM) on a computer (W2K prof.) with 512 MB
    internal memory and no limmit set for MS-Sqlserver but for JVM 128 MB doing
    the same stuff, there is no problem at all.
    
    I suspect it has something to do with a late "kicking in" of the Garbage
    Collection causing memory segmentation. So when a big chunk of memory is
    required (a large result-set from the database) no contigouis memory block
    of memory is availble in the current heap. The JVM claims more memory to
    expand the heap, grows and grows until it cosses the limmit. But I also
    tought that garbage collection takes care of that too.
    
    I hope some one has seen this behaviour and can point me in the right
    direction.
    
    TIA.
    
    Frank.

  - major version 49?It looks like the JRE classes that come with the 1.5.0 beta have their
    major version set to 49. Does anyone know of any documentation
    available for this new version of the class file format? It appears
    that the signatures can now have "+" prepended to them, which I am
    assuming has something to do with generics. I have no idea what other
    changes may be in there.
