  - Struts & JSTL <c:out>Greetings:
    
    Relative newcomer to Struts and JSTL. My question is about using
    <c:out>, pageContext, and request.
    
    My experience has been doing to following in an appropriate action
    class. Setting an object as an attribute of the request in the execute
    method of the Action Class:
    
    request.setAttribute("object1", Obj1);
    
    Then in the corresponding JSP, pulling the object off the request and
    casting it for use:
    <% Obj1 local_Obj1 = (Obj1)request.getAttribute("object1");
    
    Then being able to use dot notation to access methods of Obj1.
    
    My question is that with JSTL <c:out> the object needs to be on the
    pageContext. Do I need to explicitly set this? If so where? How does
    this tag work in this situation?
    
    Any help on the matter is greatly appreciated.
    Thank you,
    Tim Morrissey

  - Sun's WTK2.5 is asking for permission to contact network every timeI've just started using the final release of Sun's wireless toolkit
    (WTK) 2.5. It's asking for permission to contact the network each and
    every time network access happens - I'd like to switch it to asking only
    once times (or never, if possible), but can't find the option in the
    docs or via the tools in WTK2.5/bin. Can anyone shed any light on this?
    
    thanks,

  - inner classes and static membersCan somebody please tell me a practical reason why you couldn't have
    static members (not constants) within an inner class? I know that this
    is forbidden, but I haven't found a practical, concrete reason for
    this... I was wondering if this was just a whimsical decision from the
    designers of the language.
    
    Thanks a lot in advance...

  - How to Call two servletsHi Everyone,
    
    My most of programming experience is in Microsoft tools. mainly ASP. And in
    ASP we can "Include" one ASP file in an another ASP file. Can we do some
    thing similar with Servlets also..
    
    Say i want to Display two Lines on my Web page.
    
    This is First Test Line from Servlet one
    
    This is Second Test Line from Servlet Two.
    
    Where the line as it says come from servlet one and line two will come from
    servelt 2.. Or say i have a Main Servlet and now i want to call these 2
    servlets in there from my Main Servlet.
    
    Please help me there

  - Loading a properties file using ResourceBundleI try to load a properties file using ResourceBundle. However, when I print
    out the data in the map table, they are not in order as in the properties
    file.
    
    Is there a way lo load the properties file using the ResourceBundle so that
    the data in the map table are listed in order as in the actual properties
    file.
    
    Example:
    The properties file contains
    ID1
    ID2
    ID3
    After loaded and when printed out from tha map table, it displayed as
    ID2
    ID1

    - 2nd Edition. I typed it straight out of the book, and checked it

    gumballs"
    
    import java.util.Scanner;

  - SSL HostnameVerifierWas getting "hostname wrong" when connecting via HttpsURLConnection.
    Setup my own HostnameVerifier, returned true, and problem went away.
    
    However, exactly what problem did I solve, and did I introduce a
    security risk? When the substitute HostnameVerifier was called, first
    argument "String urlHostName" was identical to second argument
    "SSLSession session.getPeerHost()", i.e., the IP address of the server
    from whom the certificate was obtained. What mismatch triggered the
    call to the substitute HostnameVerifier?
    
    Thanks.

  - jsp - fetching fresh inserted data - reload issue?hi ng,
    
    i have a form, where a user can input some data.
    after pressing submit, the controller.jsp makes some
    validations and shall list up this new entry.
    in short, my problem is, that this newest entry is
    not shown - but is correctly inserted into the db.
    
    + form.jsp : holds the form
    + controller.jsp : inserts form data into db,
    and queries the db to show the newest entry.
    
    after refreshing the site by hand, the newest entry
    is listed, BUT also in the db (duplicate in db!).
    i tried some java script solutions, top.mainFrame.location.reload()
    and adding some META-TAG in the HEAD-Tag of HTML, but no
    effects...
    
    feedback is appreciated, thanks in advance.
    
    with regards,

  - Strange problem!!(it is, atleast to me!!)Although, this is not a programming or development problem instead its
    an end user problem which im facing and thought programmers /
    developers could help.
    
    I have Win XP SP2, JRE 1.5 installed with IE. Now for certain sites my
    applets dont refresh after i click them (well ofcourse i click where a
    click is expected :) this happens when i connect using my cable
    broadband connection.
    (I am connected to a local provider via LAN who provides me connection
    to the primary ISP). On the other hand evrything works as expected
    when i use dial up connection(using the phone line). Ive tried with
    many browsers and it doesn work. Ive tried everything i could. And the
    same site works well at my frnds place who has the same broadband ISP
    but hes on a different LAN and rest all settings are the same.
    
    The error i see on the console- " java.lang.NullpointerException Could
    not send message".
    
    I know the error wouldn be of much use but hope the explanation of the
    problem may have some solutions.
    
    Kindly help me.

java-programmer, doing something after so many times something has loaded Hi am currently writing a java application. The program that i am
writing allows people to be able log on to the program using a username
and password. I want to be able to edit information in a MySQL Database
when there has been a password error 3 times. How would i go about
checking to see how many times something has happened.

Any help would be apreciated.

Thank you

Put that in the database, too.

  - Browser shuts down....I am having some problems with sites that have certain Java features. At
    some web sites I get a grey box with an X... other web sites the browser
    shuts down and goes away completely. It also puts a Notepad text doc. on my
    desk top every time the browser disappears. (copy of this is below)
    
    I have done everything I can think of to resove this situation... MS JVM and
    also Sun.... Uninstal - install.... I have almost given up. It is sad that I
    can only access half of the internet. I have gone to the web sites listed in
    this forum that checks Java. Some say I am Java enabled, some have the greay
    box and others shut my browser down.
    
    I am running XP and IE 6.0.2800.1106xpsp2.030422-1633
    
    An example of a web site that shuts down my browser is here. This is just
    the web site to our local news program. www.katu.com
    
    I have been to the brink of frustration and back again more times than I can
    count trying to troubleshoot this situation.

  - JComboBox with Image, text and autocompletition of textHi!,
    I'd like to build a JComboBobox with a JLabel object which is an icon
    with text, and also i'd like to add an autocompletition to the text (an
    editable JComboBobox that when you write a text inside it, searches for
    the text starts with).
    I've tryed to use ListCellRenderer class for rebuild the visual
    renderering, but i've got also a problem with the rendering of the
    selected cell.
    Thank you for your help.

  - Hooking up jdbc to a local access databaseThe driver I am using, the default jdbc/odbc driver, in netbeans is
    not working for connecting to an access db on my hard drive. The
    driver does find the database, and connects to it, but when I set it
    up I get a "unable to obtain schema" warning. then on the icon for
    the database after im connected in netbeans, the link to the tables is
    broken. Thanks

  - encoding troublesHi all!
    
    I have a byte array of data which I want to post to an php script. So I send
    the representing string of the byte array using a post with utf-8 encoding.
    I figured java works with UTF-16BE internally, but after receiving the utf-8
    encoded post in php and converting it to back to UTF-16BE it was not the
    same...
    
    I wrote a little test and it turns out if i conver a byte array to utf-8 and
    back it wont match the original byte array, but the string representing it
    is the same:
    
    String test="some test";
    byte[] dest,temp;
    
    dest = test.getBytes();
    
    try {
    temp=new String(dest).getBytes("UTF-8");
    }catch(Exception e) { System.out.println(e); }
    
    try {
    test=new String(temp,"UTF-8");
    System.out.println(test);
    dest=test.getBytes();
    } catch(Exception e) { System.out.println(e); }
    
    if(dest==temp) System.out.println("Success!");
    else System.out.println("failed");
    
    How can I convert the UTF-8 bytes back to the original byte array? And will
    this work when posting to php? Its important the binary data remains intact
    instead of the string representation...
    
    Thanks in advance,

  - JSP NTLM extraction of windows usernameI found this username extraction code on "Real's How to..." site. The code
    work great, but I
    need help with getting it to work in my jsp/servlet
    What I have done is put this code into a jsp of my own. the jsp has a form
    on it. this form gets submitted to a java servlet, but the parameters
    (fields from the form) are all null. If I remove the NTLM username
    extraction code from the jsp, the jsp works perfectly.
    I am not sure how this java scriptlet is interfering with the field values
    of my form submission.
    
    I use the hidden field 'action' to determine what happens in the servlet...,
    but when i get the parameter in the servlet, its value is null, despite
    having the JavaScript set it just before
    submitting.
    
    Any help or insight would be greatly appreciated!

  - WMA compatible handsetsHello,
    
    does anyone have an idea where I can get a complete list of handsets
    that support WMA 1.0 and 1.1.
    
    I had a look at:
    http://developers.sun.com/techtopics/mobility/device/pub/device/ but it
    look quite outdated.
    
    Also if the handset support wma - does it mean the j2me app will be
    able to send sms messages?
    
    Thanks in advance,

  - Sams Teach Yourself Java 6 in 21 Days - Installation ErrorHi,
    
    I have just bought the book Sams "Teach Yourself Java 6 in 21 Days",
    and am getting an error installing the JDK supplied with the book.
    
    After running "start.exe", I select the AMD 64 installation package.
    After the InstallShield package loads up, I get an error, "This
    installation package is not supported by this processor type. Contact
    your product vendor.".
    The installation then aborts and I cannot get any further.
    
    I have an HP PC with AMD Athlon 64 X2 processor, running Windows
    Vista.
    
    Has anyone installed the software successfully on a similar platform,
    or knows what might be wrong?
    
    Thanks in advance for any help.

  - Why isn't new used in the following.In the following:
    
    public class toupper {
    
    private static void upper(){
    
    String a = "chad";
    System.out.println("Upper Case is:" + a.toUpperCase());
    
    }
    
    public static void main (String[] args) {
    upper();
    }
    }
    
    Why isn't the line
    String a = new String();
    
    Necessary? I thought this line might be omitted because for whatever
    reasons I was thinking toUpperCase() was a static method. It isn't.
    Because when I change the line:
    
    System.out.println("Upper Case is:" + a.toUpperCase());
    
    to
    
    System.out.println("Upper Case is:" + String.toUpperCase());
    
    I get the following:
    
    $javac toupper.java
    toupper.java:6: non-static method toUpperCase() cannot be referenced
    from a static context
    System.out.println("Upper Case is:" + String.toUpperCase());

  - NetBeans IDE 3.5 does not runHi all,
    
    I've installed NetBeans IDE 3.5 on Windows XP. But if I try to start it,
    a message box shows "cannot load jvm.dll". This library does exist in
    a subdirectory. My questions are:
    
    1) Is NetBeans IDE 3.5 a stand-alone software, i.e. can it run without
    other software, or should a java SDK be installed?
    
    2) If NetBeans can run without java SDK, maybe one must set the path for
    jvm.dll. How can it be done?
    Many thanks!

  - Displaying SIGNED SHORT images in Java,Hello,
    
    Given an array of SINGED shorts gray values, how can I create a corresponding

  - Java facade to Ada code?Hi. My team has a bunch of legacy Ada code. Our new code is being
    written in Java. However, we still have many complex algorithms
    written in thousands of lines of Ada. Rather than rewriting the
    tested/validated Ada code in Java, we'd like to create a Java facade
    that would delegate to the Ada code, thereby making the Ada code
    available to newer Java client objects. Is this reasonable (as opposed
    to rewriting everything in Java)? Anyone know what
    mechanisms/libraries would support such an approach?
    
    Thanks!
