Hi!!
I'd like to write a method that convert given string to string which

Is that true?
If it is, then the follow-up question is how can I flush it?

I'm new to eclipse, and I'm having a problem using the debugger. When
I step into a function call, and step through it, once it hits the
"return" it doesn't jump back to the caller, it seems to just hang
there? Is there anyway to get it to return to the caller?

I have a method (fragment below) that takes a File type "outFile"
as the output file.  However, if the user of this method specifies
"null" for that parameter, I want to make the output go to standard
output instead of a file.

I'm trying to implement Tiles ( from Struts 1.3 ) into a web that is
NOT using Struts. I've found and followed instruction on doing this

I just wanted to clarify.  I noticed that improvements were made to
double buffering in Java 6 (true double buffering is now used) as

I am trying to run my app and am getting this error:

I've followed Sun's "The Java Native Interface" by Sheng Liang on
creating a JNI test/example. Unfortunately it isn't working for me.
This leads me to believe that either I'm doing something stupid or

I'm wondering if it is possible to find out the codebase value from your
java application when using JWS?
If not, what is the best approach for the following problem.
I want to be able to look up a .exe, and download it from the install

I always thought I can use "==" to compare if two Strings are equal(with
