I've written an FTP server and am wondering how I am supposed to test it.
I'm the author so I know what I'm doing and how the server is and isn't
supposed to work, but there are idiots out there who will undoubtedly
mess things up.

I want to convert a BufferedImage that has a DirectColorModel such as
TYPE_INT_RGB to a BufferedImage with an IndexColorModel.
Right now I am doing it this way:
BufferedImage buffered = new BufferedImage( width,

I'm not familiar with LDAP except using JNDI to look up EJB homes and
data sources.
Now I have a task to create a People entry and put it in a group in
Java.

Have anyone of you succesfully created datasource in Tomcat 5.5.x?
I can't get it work. I  have tried to do everything what Tomcat's
documentation
says but it does not work.

Are there any UML diagramming tools out there that support new features
of Java 5 such as generics and enum?  I have to do some reverse
engineering on an existing code base and really rather use a tool to
automate the diagram creation.

I originally had some code (for doing an LDAP search using ldapjdk.jar)
that looked something like:
while (results.hasMoreElements())
    {

    If I'm writing some native code using the C++ JNI API and my
    C++ code has a static object with a destructor, is it
    guaranteed that said destructor will be called before the
    process terminates (as it would be if this were plain C++)?

in the following program I expect the JRadioButtons
be placed on the left edge. But they start at the center.
What should be done to "move" them to the left? Thanks.

I need to set up a value of type java.net.URL in server.xml so that
it's accessible via JNDI from servlets running under Tomcat.
I.e., I need to set up a value that I can get in the code like this:
URL url = (URL) initialContext.lookup("url/configURL");

Does anyone know how to use POI to read word document?
Has anyone tried?

I'm again here with a problem:
I use TextArea to report to the user what the program
is just doing. But it seems to me that, if the program
takes quite a while to run, the report messages appear

Here is a functionality that I need to build into my J2EE webapp (built
on IBM's EAD4J framework) ...
A page is displayed in html which looks like a spreadsheet. I need to
build this functionality into this page... if the user wants, the user

I've tried to use Vector.toArray() to copy the content of a vector
to an array without success. The vector contains only object of
the class MyClass. I've made the following attempts:
MyClass[] arr = new MyClass[myVector.size()];

I hope this post is not off-topic here but I couldn't find a more
appropriate newsgroup.
I want to overload methods in the JNI and have a problem with the method
name which has to be extended with two underscores and the encoded argument

I'm writing a method that will receive as an argument an object (any
object) and does some stuff depending on which class it belongs to or
which interface it implements (in particular, wether it implements the
java.util.List interface). To do that, I need to be able to discern
