Hi,

The time it takes for a development cycle is critical for a developer. Even though Eclipse is not bad compared to other development environment, I am looking at ways to improve it.

Here is the problem: I use a prevayler database in a plugin. The database is about 6 megs (I cannot really make it simpler - I need the data to test the plugin). Each time I want to test a new function or a modified code, this data need to be reloaded (I use "run-time workbench" using another eclipse directory - only the platform's plugins).

I read somewhere that it is possible to unload and reload a class or a library in real time. Is it possible to do it with Eclipse in a run-time workbench?

If you use JDK 1.4.1 in Debug mode, you can make simple code
modifications, save (recompile) the class and it will be reflected in
the running code.

Limitations: No new methods, no method signature changes, no class
hierarchy changes.
Adding new (not inner) classes is OK.

I did not know that. Running in the debogger is a bit slower, but this
is REALLY great. Thanks so much!
