In case you are in the area, I’m delivering a introduction to Eclipse RCP at the JUG Mannheim on 22.04.2009. The presentation is planned to be in German.

Eclipse Workspace Location – Where is my current workspace located?
If you start Eclipse with the -startLocation flag (eclipse -showLocation) then the titlebar of Eclipse will display your current workspace location.

Using Eclipse Java Compiler Errors/Warnings – Improving your code quality
If you want to setup a more restricted development environment to create Java code with higher code quality, have a look at the Eclipse preferences settings under Java -> Compiler -> Errors/Warnings.
Here you can define how the Java compiler should react to certain common programming problems, e.g. you can define that “Assignement has no effect (e.g. x=x)” causes an error in Eclipse.
I highly recommend the usage of restrictive settings here to improve your code quality. For example I consider the following settings as important:
This should only be your first step, additional checks are provided by Findbugs and Checkstyles Using FindBugs and Checkstyle in Eclipse – Tutorial
Eclipse WTP – Deployment location of the local Tomcat
If you ever wondered where Eclipse WTP deploys your web application during development (if you use the local server option in Eclipse) you find the result of your deployment under:
Workspace-> .metadata -> .plugins\org.eclipse.wst.server.core\ and then tmp[number]\wtpwebapps\project name
Update for Eclipse 3.5 (wtpwebapps in the path seems to be new)
Quick Fix – Type conversion for instanceOf
I just realized that Eclipse provides a quickfix for the type conversion after an instanceOf check. This is so helpful as it save this annoying typing.
What a wonderful tool!

Eclipse: Filter / Exclude certain packages during “Organize Imports”
The Eclipse “Organize Import” Feature (Cntr+Shift + O) allows to automatically import the packages which are used in a program. If there are several options Eclipse suggests all available classes and the user has to select the right one.
If you are working mainly with SWT the fact that Eclipse does also suggest java.awt and javax.swing classes can be annoying.
To prevent this you can add a “Type Filter” under Windows -> Preferences -> Java -> Appearance -> Type Filters. Then these classes are not suggested anymore.
