  - help my first java programThis is my first attempt at java
    
    here it is

  - mouse button 2 is always meta-modified?I have a program in which I wanted to allow the user
    to use either Alt or Meta to indicate the same
    modification of a mouse click. When I look at what's
    returned by getModifiersEx(), I am surprised to
    discover that an unmodified Button2 event produces a
    value of 256, which also happens to be the value of
    MouseEvent.META_DOWN_MASK. The result is that a plain
    Button2 event looks like a Meta-modified one. This
    cannot be right; and there is no analogous problem
    with Button1, which produces 0 for an unmodified
    event. In fact, if I hold down any combination of
    Shift, Control, and Alt when clicking Button2, then the
    256 bit is _not_ set but the appropriate combination
    of others is set. I am on a PC and I do not actually
    have a Meta key; but I wanted folks who do have one to
    be able to use it in preference to Alt. What's going
    on here? Is there a solution to this problem? (In
    the meantime, I have just removed my Meta-modifier
    option so that I can successfully detect that a Button2
    event is unmodified.)
    
    I am using SDK 1.4 under Windows 98.

  - Hibernate: @SecondaryTable causes ORA-00918I have to tables 'first' and 'second':
    
    CREATE TABLE first (
    first_id int IDENTITY NOT NULL,
    first_value INT NOT NULL,
    PRIMARY KEY (first_id)
    )
    
    CREATE TABLE second (
    second_id int IDENTITY NOT NULL,
    first_id int NOT NULL,
    second_value INT NOT NULL,
    PRIMARY KEY (second_id)
    )
    
    I want to join these two tables into one entity using @SecondaryTable.
    The columns that are used for joining are named the same in both
    tables ('first_id'). Hibernate creates a query like this:
    
    SELECT f_.first_value as first_value_,
    s_.secondValue as second_value_
    FROM first f_,
    second s_
    WHERE f_.first_id=s_.first_id(+)
    and first_id=?
    
    In the last line Hibernate "forgets" to add a qualifier to 'first_id',
    so I get an "ORA-00918: column ambiguously defined" error.
    
    Any ideas?
    
    Thanks,
    Ralpe

  - ArrayList Marshalling Question....Hi All,
    
    We are trying to invoke EJB methods on simple stateless session beans
    from an Applet running remotely. One of our methods needs to return
    an ArrayList of Serializable objects.
    
    We have encoutered the following error: (please see end of post for
    stack trace).
    
    Some research has yielded the fact that even though the ArrayList
    class in Java implements serializable, the Object[] member is not
    serializable, even though the objects that we are putting into the
    array are serializable.
    Because our applet is REMOTE, we are using RMI-IIOP to access our
    Beans which are on iPlanet 6.5.
    
    The beans function properly for all base types and for simple
    serilizable objects, but sadly, an ArrayList isn't one of them.
    
    Has anyone else encountered this problem? Suggestions or alternatives
    to using the ArrayList class would be appreciated as well.
    
    Thanks in advance...
    
    Omer/John.

  - Encrypting Java Code
    
    I provide a Web service that is mostly JSP with a few java classes
    thrown in. I want to give my customers the ability to down load a
    subset of the service's functionality (JSPs) to run offline.
    
    How can I encript the code so that it cannot be reversed engineered?
    If it encripted, is there a performance hit?

  - T-SQL print statement ...Hi all,
    
    I have a java app that connects to Sybase using jConnect 6.05
    and calls a stored procedure using the CallableInterface.
    
    Any print statement within the stored procedure becomes a
    SQLException on the java side???? e.g.
    
    com.sybase.jdbc3.jdbc.SybSQLWarning: Beginning REORG REBUILD
    of ...
    
    why if it is a SQLWarning is being thrown as a SQLException?
    
    how can I disable this (very stupid) Sybase behaviour?
    
    - is there anything like "set showoutput off" or disable output session
    parameter? or even a jConnect parameter to disable SQLException on
    SQLWarning occurrences or whatever?
    - Removing the print statements out of my procedure is not enough as
    I call some other internal Sybase procedures that also seem to be
    printing crap out.
    
    Many thanks in advance,
    Best Regards,
    Giovanni

  - Converting a string to an integer<Question>
    
    Why does the NumberFormatException get thrown when the String argument
    is not empty?
    </Question>
    
    <Background>
    
    I was reading the Sun Tutorial and happened across the section on integers:
    
    http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html
    
    I saw the bit on octal and hex representations and thought that I might
    be able to take a string containing..oh say "O23" and use the
    Integer.parseInt method to convert it to an integer. After all, the
    tutorial does say
    
    The prefix 0 indicates octal, whereas 0x indicates hexadecimal.
    
    int decVal = 26; // The number 26, in decimal
    int octVal = 032; // The number 26, in octal
    int hexVal = 0x1a; // The number 26, in hexadecimal
    
    Here's my code:
    
    package just_playing_around;
    
    public class WillThisWork {
    public static void main(String [] args) {
    String s = "O23";
    int x = Integer.parseInt(s.trim());
    System.out.println("s as a string is " + s);
    System.out.println("s as an integer is " + x);
    }
    }
    
    And here's the error I get when I run it
    
    Exception in thread "main" java.lang.NumberFormatException: For input
    string: "O23"
    at java.lang.NumberFormatException.forInputString(Unknown Source)
    at java.lang.Integer.parseInt(Unknown Source)
    at java.lang.Integer.parseInt(Unknown Source)
    at just_playing_around.WillThisWork.main(WillThisWork.java:6)
    </Background>
    
    <Research>
    1) I did a google search on cljp and found the following post
    
    http://groups.google.ca/group/comp.lang.java.programmer/browse_thread/thread/bc297073502432fa/d7610d111ecc7ceb?lnk=st&q=java.lang.Integer.parseInt(Unknown+Source)&rnum=7&hl=en#d7610d111ecc7ceb
    
    If you will notice Patricia's post
    
    I think this is the critical data. It claims that there was an
    Integer.parseInt call on line 72 with the empty string as input.
    
    Does that make sense?
    
    Patricia
    
    2) I tried to eliminate the probable causes of the "empty string" in
    the following sequence
    
    2a) I removed the parseInt and print for x from my code.
    
    package just_playing_around;
    
    public class WillThisWork {
    public static void main(String [] args) {
    String s = "O23";
    // int x = Integer.parseInt(s.trim());
    System.out.println("s as a string is " + s);
    // System.out.println("s as an integer is " + x);
    }
    }
    
    s as a string is O23
    
    2b) In the same program, I did the trim and assigned the value to a new
    string so that I could see what the result of the string was without
    disturbing the original. I also added a comparison to see if indeed
    both strings were the same.
    
    package just_playing_around;
    
    public class WillThisWork {
    public static void main(String [] args) {
    String s = "O23";
    String y = s.trim();
    System.out.println("s as a string is " + s);
    System.out.println("y as a string is " + y);
    if (s.equals(y))
    {
    System.out.println("They are the same");
    
    }
    else
    {
    System.out.println("They are different");
    }
    }
    }
    
    s as a string is O23
    y as a string is O23
    They are the same
    <Research>
    <Theory>
    Either the runtime error I am getting is misleading (see Research.1> or
    the runtime error is pointing me to something else, something more
    insidious.
    </Theory>
    <Followup>
    Where am I going wrong? Did I mis-read something somewhere or is what I
    am trying to do just not do-able using the tools I have available to me
    right now?
    </Followup>
    
    Thanks for your help

  - InputStream is abstract, but...System has a static data member called in which is an InputStream object,
    and has a non-abstract read() method - but the read() method of InputStream
    is abstract.
    
    Is the answer something to do with it being native code?

  - jsp:include and servletshello,
    
    I have the following problem:
    
    I would like to evacuate the logic from my jsp files in servlets. servlets
    provide database contents prepared in HTML tables, the jsp files are
    supposed to offer the graphic structure of the intranet application.
    
    how does the path detail have to look?
    
    thats my current include command:
    
    <%@ include file="/proj/mdswpu/classes/ShowList" flush="true" %>
    
    the whole thing is located in the directory webapps/Root/weave INF/classes.
    
    do the path details cause problems or is it due to the servlet? is it no
    matter whether doPost or doGet method is used?
    the servlet delivers HTML via printwriter.
    
    thank you for the help in advance ....

    the community. The code for Project GlassFish goes into building Sun's
    Application Server PE 9, and the Reference Implementation of Java EE 5.
    In this Ask the Experts session, you'll have the opportunity to ask
    questions about Project GlassFish, and get answers from Project
    GlassFish Manager, Jim Driscoll, and Project GlassFish Community Leads,
    Carla Mott, and Amy Roh.

  - Export HTML table inside JSP to Excel using JavaWhen I generate this table inside this JSP page, it will offer a
    button for user to click if he/she decides to export the HTML table
    into an Excel sheet (which get displayed directly back in the
    browser), then user can save his/her this Excel spreadsheet into his/
    her local file system.
    
    Can someone help me on how I can convert this HTML table to Excel
    using XSLT? Sample code would really help also, if there's any URL to
    refer me to.
    
    Is it a good idea to generate the Excel file (as temporary file which
    to be sent back to browser later if user click the button) at the same
    time when the HTML table get generated? Then remove this temporary
    Excel file later.
    
    Any comments? Thanks,

Never use GNU licenses. They are all viral and
contaminate whatever they touch. Very similar
to the "Bog of Eternal Stench". Look at the
other open source licenses for a better alternative.

  - AppletContextHi,
    
    I'm a bit of a newbie to java so any help would be gratefully appreciated.
    
    I have a java applet which displays a graph depending on whther there a
    more nodes in the hierarchy
    you can navigate the graph to you get to a leaf node (no more nodes).
    
    If I click on a leaf node it is supposed to pass a product Id to a php
    script in another frame.
    
    I understand the showDocument method of AppletContext will do this with the
    following parameters . .
    
    showDocument(node.url, TARGET)
    
    where TARGET = framename.
    
    But I'm not really sure about the URL parameter.
    If it is all the same webpage why is this necessary ?
    What should I put in here ? my website address ?
    definitely not clear on this.

  - Secure PackagesIs it possible to make packages with non-class files (say, a folder,
    or Stuffit archive) that are accessible only to a class file within
    the package? Could it be set up so that even a UNIX root user wouldn't
    be able to access the files? Would it be necessary to encrypt the
    files (and use a Java class to decrypt them) and if so, how? Sorry for
    my inexperience here. I'm really kind a beginner at Java programming,
    but I need some of these functions for the program I'm writing so...

    Any one had any simialr issues
    
    Does any know if tiger resolves this?

    POJO is good, but any design paradigm can be taken too far. Mutable

    Now we have a POJO object that uses our bean as builder.

    I'm not sure. There's no run time type for generics or parameterized
    types, so I'm not sure how you'd detect the generic information.

    Good point. assignmentLoad() would have access to the class's private
    fields. I'm used to thinking about beans and Swing objects.

    See the builder example above, and Lew's point about using builder
    objects and throwing errors.
    
    If possible, an object should be constructed in a legal state. If not,
    you'll have to check for errors at runtime. As long as this is
    encapsulated in the class, it's still safe.
    
    public void addGuest( String name ) {
    if( number == 0 || floor == 0 || beds ==0 ) {
    throw new RuntimeException( "You blew it pal." );
    }
    // ..
    
    Now you can't add a guest to an uninitialized room.

  - java LookAndFeelHi,
    
    What is the easiest way to change the default font that is used
    throughout your application. My client has complained that the font is
    too small. Eveything I use is the default LookAndFeel and I don't want
    to have to play around too much. Is there a simple way to just change
    the font size so that JLabel, JTextField etc. will use the larger font
    by default?
    
    Thanks,
    
    Lionel.

  - CMP without entity beans ?Hi everyone,
    
    I will soon be working on a EJB 2.1 legacy application (running on
    JBoss), so i've started studying "JBoss at work, a practial guide".
    
    In this book, the CMP chapter uses Hibernate ((using .HAR archives)
    instead of Entity Beans. As far as I understand, this feature is
    specific to JBoss, maybe because Entity Beans are implemented with
    Hibernate.
    
    I have the 2 following questions :
    
    - Is the same behavior possible on other application servers ? (ie :
    CMP with Hibernate instead of Entity Beans ?)
    - Let's say I want to use another persistence strategy (ex : Ibatis or
    straight JDBC), can I still use CMP ?
    
    Thanks for helping !

  - ANT MultipleChoiceInputRequestI have a target that checks if backup directories exist and if so, it
    asks the user for input. I'd like to minimize the amount of typing the
    user has to do and present the user with a list of choices that they
    can just enter the number of the option they want.
    
    Using the default inputhandler works fine, but it's not very elegant.
    I've read (very little) about
    org.apache.tools.ant.input.MultipleChoiceInputRequest, but I can't
    find anything on the Internet or in the manual. I'd like to see how
    this works, as I may need to use this elsewhere. Anyone ever tried it?
    
    I'm using Ant 1.5.1 on Windows 2000.

  - Printing of stored documentsHi, I want to print serveral documents (pdfs, jpegs, rtfs) which are
    stored as blobs in a database. A webpage presents the information
    about all the related documents and now I want to print them at once
    (at the moment, the user picks up every document and print it). Who
    knows, how to do this comfortably?
    
    Best regards

  - I/O filewriterHi all
    
    I must make a simple database for project,I designed catalog and page
    structure but I have no experience about java i/o ,can someone tell me
    how it append byte into file without erasing
    
    I found some example but It only converts strings to byte and append it
    .the problem occured. it erased the old data.
    
    in fact I can buffer old data but maybe java class thinks a simple method.
    
    Thanks all

  - Media types available in MIDP2.0Hi. I'm writing a MIDP2.0/CLDC1.1 app, and i'm trying to work out if
    which devices support playback of mp3 files from java.
    Does anyone know if there is any way of enumerating the available media
    types (e.g. 'audio/x-wav') available on a device?
    Or failing that, whats the MIME type for an mp3? And has anyone got
    MIDP to play mp3.
    Cheers!
