From my Eclipse HowTo for Spring Live:
TIP: In order to clean up the project view in Eclipse, you can hide the files you don't need. First of all, make sure you're in the Java Perspective (Window → Open Perspective). Then click the little (down) arrow in the top right corner of the Package Explorer pane. Select Filters,
check the "Name Filter Patterns" and type "*.jar" (no quotes) in the
text field. Then in the list of elements, scroll down and check Referenced Libraries. Click OK to continue.
Another useful Eclipse trick is to use abbreviated package names. You
probably won't need it on this project, but its nice on projects where
you're inflicted with super.long.package.name.syndrome. Go to Window →
Preferences → Java → Appearance. Check the "Compress all package names"
checkbox and type "1." (no quotes) in the text field.
