  - 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
    
    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,

  - 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,

  - 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,

  - 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.

  - 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.

  - 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...

java-programmer, Creating us map graphics? Hello,
Does anyone know of any Java freeware that can help me generate a
US map with states being different colors? I am running JDK 1.3 for
Solaris. My intention is to color code states based on the number of
users wwe have from each state.

Thanks, - Dave

  - 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!

  - 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.

  - 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!

  - Tiers, Layers, Models and Design Patterns (Model-2 of Struts)Hi,
    
    I'm busy investigating the Implementation View of the 4+1 architectural
    views of RUP.
    
    I'm getting a bit confused about the difference between Tiers and Layers and
    how to
    get my business logic model + struts into it. I would like to invite you to
    join a discssion
    of what is actually meant by layers and tiers, how they relate to eachother
    and how
    for example struts, consisting of a servlet controller, an action, a form,
    and a JSP view,
    is "resting" on the layers and partitioned over the tiers. Besides that
    assuming that the
    system in integrating via XML to a back-end system I wonder how this in
    reflected in
    tiers and layers.
    
    The tiers I'm thinking of are:
    
    - Presentation (= on the browser)
    - Web (= JSP and servlets on the server)
    - Business Logic (=EJBs on the server)
    - Enterprise Information System (=system to integrate with)
    - Database (=back-end database)
    
    Hope this is not enough to discuss in one thread and that the problem I have
    is clear.
    
    Kind regards,

  - login username from databaseHi,
    
    I have a login window with a username and password fields. The

  - 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.

    Is there any way to create a layout manager consisting of two cols where
    the left has a width of 100px and the right one uses the rest of the

    Something like HTML's <frameset cols="100,*"....>

  - 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());

  - 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!

  - 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
