Unit Testing for DB Applications
DbUnit is a JUnit extension (also usable with Ant) targeted for database-driven projects that, among other things, puts your database into a known state between test runs. This is an excellent way to avoid the myriad of problems that can occur when one test case corrupts the database and causes subsequent tests to fail or exacerbate the damage.
DbUnit has the ability to export and import your database data to and from XML datasets. Since version 2.0, DbUnit can works with very large dataset when use in streaming mode. DbUnit can also helps you to verify that your database data match expected set of values.

Java tips – Examine tracebacks without stopping Java
You can dump out tracebacks of a Java process at any time, and see what line of code is being executed by each thread. This is VERY handy for analysing thread problems, like deadlock.
At the NT-DOS prompt, just type control-break (a little used key on the upper-right).
On Unix, send a QUIT signal to the java process group. Here’s how to send a QUIT signal:
% kill -QUIT -32352
where 32352 is the process group ID (PGID). You must include the minus sign before the PGID. Get the PGID with this command:
% ps -e -o ‘pgid user fname args’ | grep java |sort -n
The first column will contain the PGID. The QUIT signal is often bound to control-\ (backslash).
I map the QUIT signal to control-A with
% stty quit “^A”
You’ll get the tracebacks printed to the screen, without causing the program to exit. This dump is more thorough than you get from an uncaught exception. Read more at http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/stack.html
To see uncompiled line numbers, use the option “java -Djava.compiler=NONE com.lgc.stuff” when you launch the process in question.
I have not found a way to send a signal under Cygnus bash on Windows.
(Java tips)
====================
Another way could be using jstack -m %p (jstack).

Better Large Project Overiview
The goal of the Mylar Technology project is to help the Eclipse UI scale gracefully to very large workspaces. Currently Eclipse views can quickly become overloaded with elements unrelated to the task at hand. Mylar monitors programming activity, actively searches for related elements, and extends the Eclipse UI to focus on the elements of interest (e.g. by filtering uninteresting nodes from the Package Explorer, visible to the left).
