  - Casting from Object to intHi there!
    
    I'm developing a method which receives two Object parameters, and I need
    to cast one of them to int. How can I do it?
    
    public method(Object a, Object b){
    this.b = (int)b; // doesn't work!
    this.a = a;
    }
    
    Thanks in advance!

  - Java algorithm (diff) question.I have two CSV files (file1 and file2).
    Each file contains 50,000 + lines. Each line is very long.
    The first entry in each line is a key as shown in the example below.
    
    Example:
    key1,val1,val2,val3....
    key2,val1,val2,val3.....
    etc
    
    I would like to do a "diff"(unix like) between file1 and file2 and
    find out
    the lines that are different. The entries in each file are not
    necessarily sorted by key.
    
    Approaches I considered.
    1. To load all the entries into a hashmap using the key's as a key and
    the rest of the line as a value. This is a problem because of memory.
    
    2. To generate the hashcode for each line and use the key and the
    hashcode to
    store in a hash map and do the comparison. The problem here is that
    two different strings could have the same hashcode (false positive).
    
    Any suggestions would be appreciated.

  - What's the effect in different classpath set?525 wrote:

    Neither one works. The environment variable is 'CLASSPATH', not 'classpath',
    and you don't put spaces in it.
    
    Even after correcting those errors, the second form will not pick up the JAR
    files, nor is the first form isn't necessary because the JARs in the
    $JAVA_HOME/lib/ directory don't need to be part of the classpath explicitly.
    
    In any event, all your questions should be answered by the information in the
    documentation:
    <http://java.sun.com/javase/6/docs/technotes/tools/windows/classpath.html>
    
    I strongly recommend that you do not use the CLASSPATH envar, but use the
    -classpath (or -cp) option to your Java tools. CLASSPATH is far too global.
    
    Also, read
    <http://java.sun.com/javase/6/docs/technotes/tools/findingclasses.html>

  - Handling multiple attributes with w3c ElementQuestion from a new java programmer (I inherited this project when our
    dedicated java guy left)...
    
    It seems in his XML documents, there is usually only on attribute for
    each element..
    i.e. <ClubMember officer="T">
    
    and to generate this I use:
    
    Element retVal = DomUtiliy.addElement(parent,
    "ClubMember").setAttribute("officer", "T");
    
    In new new case, I'd like to create something like:
    
    <ClubMember officer="T" elite="T" current="F">
    
    and I can't find a method in the org.w3c.dom.* namespace to do such a
    thing as .addAttribute to an Element. It seems you can
    only .setAttribute. Is there an wasy way to add mutiple elements? An
    example out there somewhere?

  - Flush ResultSet to BrowserHi. I am querying an Oracle 9i database that in some cases will return
    very large resultSets (up to 95,000 rows). I am using Java Server
    Faces for my front end but I am having some major performance issues,
    for obvious reasons. My question is this: Can I start flushing the
    database results to the textarea in the browser before the query
    completes to give the illusion of speed? Here's the current slowly
    working code. Thanks in advance for your help.

  - ResourceBundle vs System.getPropertyOur team is trying to decide how to load an IP address and port used
    by a single class that creates a socket. This class is invoked in a
    servlet container.
    
    My preference is for ResourceBundle. Another developer feels strongly
    about System.getProperties.
    
    Any clear rules on which method is best for particular situations?

  - print pdfs from java java programI seen a handful of libraries that can produce pdfs. I'm looking for a way
    to print them and possibly print preview them from a java application. Does
    anybody know of a tool that can do that? I'm using iText (if it makes any
    difference).
    
    Hmm... just as I was writing this, I saw a mention of another library,
    jpedal (jpedal.org) and it says it can "view" them. I'm going to try it out
    tonight but I doubt it will do printing.

  - Subclassing a text area..I would like to create a component that is based on the TextArea, but I'm
    not really sure where to start. Basically this component would behave the
    same as a text area, but would highlight certain portions of the entered
    text as it is entered e.g. incorrectly spelled words.
    
    I would like to package this as a separate component that I can add to
    other projects I'm working on.
    
    Is there a good text that would provide examples on how to do this sort of
    thing?
    
    Thanks.

  - JavaMail is not working on FreeBSD 6 (amd64) using linux-sun-jdk14I'm trying to port an application currently running FreeBSD 5.3 (i386)
    using jdk14 to FreeBSD 6 (amd64).
    
    First I tried jdk14, with this result:
    hallandsen# make -V IGNORE minimal=YES
    "is only for i386," "and you are running amd64"
    
    Then I tried linux-sun-jdk14.
    It installed successfully, but there seems to be a problem
    sending emails with JavaMail.
    1 System.out.println("## New MimeMessage");
    2 Message msg = new MimeMessage(session);
    3 System.out.println("## New MimeMessage passed");
    
    It never reaches line 3, no sign on what's wrong.
    
    Has anyone of you an idea of what to try or am I out of luck ?
    
    Thanks,

  - An enum mystery solvedI was baffled why the compiler would not let enum constructors access
    the enum's static variables.
    
    I consider it a bug, but an understandable bug.
    
    I think the reason is the enum invokes the constructors for the enum
    constants in static init code. Somebody was worried that the static
    initialisation would not be complete. Yet it is quite safe since the
    enum constants are the last bit of static init.

java-programmer, CLASSPATH help using classes and jar files. I am new to java, what is the correct way to define CLASSPATH for the
files like test.class or test.jar. In unix if I want to provide a
PATH to an executable like /userfiles/test.exe I would do the
following:

PATH=/userfiles

This provides a directory to search for.

In JAVA, I thought it was the same, but in some instances on our system
I see it point to the exact class file. For example:

CLASSPATH=/userfiles/test.class

Shouldn't it be CLASSPATH=/userfiles ?

The same for JAR files. Should it be CLASSPATH=/userfiles, or
CLASSPATH=/userfiles/test.jar

Thanks.

  - Java and X509 Certificates .. help!!Hello,
    
    I need some help! I would like to know if it is possible to get, from
    the browser (web client), the server X509 certificate used by it in an
    already SSL established session with the client (browser). As in the
    server side, with your application you can get the client X509
    certificate used by the client in order to authenticate himself, it
    should be an analogous process or API in the web client to get the
    server certificate.
    
    The aim is to develop some client script (preferable JavaScript, but
    could be with Java Applet) in order to deal with the server X509
    certificate fields.
    
    Can you help me? Thanks in advance!!

  - Problem wih the progressbar in statusbar with frames in IEHi, i've an anoying problem.
    
    SITUATION
    I created a webpage with CSP (crystal Enterprise ASP pages) and
    Javascript. The page consists of frames. When someone pushes a button
    in one frame (grouping of cubes and reports) i load another frame with
    report and cube links. When someone pushes a report or a Cube link an
    ActiveX or a DHTML viewer is started.
    
    THE PROBLEM
    The problem is that when someone pushes a button in the GroupFrame the
    reports and cube links are loaded correctly, but the progressbar below
    in the statusbar keeps running. It's showing that not everything is
    loaded yet, but everything is loaded!!!
    
    The next time when i push a button in the group frame all the links
    are corerectly loaded but now there's is no progressbar (so correct)
    and then the next time when i push the link in the groupframe again
    Again a progressbar is continously shown (what the heck??!!)
    
    It has something to do with frames because when i load the information
    in a pop up screen it doesn't show a progressing progress bar.
    
    I hope that someone can help me with this problem..
    
    Thx

  - Classes in jar can't load - why?I've just created a jar-file containing some classes that I've made. I have
    made this jar file in Idea IntelliJ's AntBuild. However, when I try to use
    the jar file in a project I get the following message:
    
    cannot access Teleadress.DMP2004.DTDClasses.CompanyResult
    bad class file
    D:\IdeaProjects\DTDFileTest\lib\DMP2004_DTDClasses.jar(Teleadress/DMP2004/DT
    DClasses/CompanyResult.class)
    class file contains wrong Class: CompanyResult
    Please remove or make sure it appears in the correct subdirectory of the
    classpath
    
    The thing is that it works perfectly when I open the jar-file with WinZip
    and copy all the class-files to the classes folder in my project. Moreover
    when I write Teleadress.DMP2004.DTDClasses. the autocomplete function shows
    a list of all my classes including CompanyResult. However, as soon as I
    chose CompanyResult it turns red meaning it can't be found. This is also the
    case with all the other classes in my jar.
    
    Why is this? I've checked other jars and the only thing that is different is
    the manifest-file which in my case is more or less empty.

  - Broken behavior of java.io.File()I'm seeing several examples of broken behavior with java.io.File():
    
    * mkdirs() sometimes returns false, despite succeeding (the directories
    exist afterward on the
    filesystem)
    * exists() and isDirectory() sometimes return false when called on a
    File object right after a
    mkdirs() after which the directory and its parents existed, as
    observed using Winblows
    Exploder.
    
    What is going on here? Is there even a way to test for the existence of
    a directory with 100% accuracy?

  - JGSS Kerberos issuesI'm trying to implement single sign-on using jCIFS. I'm having
    difficulties with Kerberos on some clients. For some reason, the web

    working fine. The problem I'm having is when a client tries to use
    Kerberos to authenticate. I've tried setting jCIFS flags to turn off
    Kerberos, to no avail. I've read the documentation and configured
    Kerberos accordingly. I just can't get past this error. Relevant info

  - About Reflection (or not)Hello everyone..
    Here I am again for another question.. :P
    Suppose we have the following class
    
    public class Test {
    private Test2 test2 = new Test2();
    public void testMethod() {
    test2.test2Method();
    }
    }
    
    Is there a way, using anything (probably reflection) to know that the
    method testMethod of this class calls test2Method() method of Test2
    class..? Or the other way around.. Is there a way to know what classes
    call Test2's method test2Method()..?
    
    Any help/reference/book etc. is appreciated.
    Thank you very much.

  - Mapping a UNIQUE pair of keys in a MySQL table into .hbm.xml in HibernateIn my table, if I have the following UNIQUE pair of keys,
    "UNIQUE (SUBJECT_AREA_ID, DISCIPLINE_ID)"
    How do I represent this in .hbm.xml in Hibernate?
    Is that the composit-id that I need to you?
    Thanks,

  - Drag and drop an URLHello,
    
    can you give an advice please? I learned how to drag and drop an URL from my
    web browser to my Java application. But it does not work as I would like.
    For example if I drop URL http://java.sun.com/ my application receives
    http://java.sun.com/Java Technology where "Java Technology" is not the part
    of URL but page title. Is there any way how to receive pure URL without the
    page title? I worry that by cutting off everything after the last slash I
    can damage some URLs. I use DataFlavor.stringFlavor.
    
    Thank you! Vojta

  - Setting column titles in JTable, TableDialogEditDemo exampleHello,
    
    This is no doubt a really dumb question, but I don't see where in the
    example TableDialogEditDemo.java (from Sun's Java examples) that we "tell"
    the table to have one fixed row, to make it grey, and to use getColumnName()
    for the column headers? (Stated another way, what would I do differently if
    I didn't want the column titles to be grey, for instance?) The full java
    listing is below.
    
    Thanks,
