thanks for the tips. I knew about the "step into", but with a huge method stack, it can take forever to click deep into the JDBC driver.
I'll have a look at JadClipse.
I did find after searching for a few hours more (the eclipse site's mail/news interface makes it so hard to find something) that you can simply do this:
- Open the JAR file in the Package explorer (click the +)
- Browse to the class file you want to breakpoint
- In the outline view, click on the method you wish to breakpoint
- Select 'Toggle Breakpoint'
of course, this only lets you set a breakpoint around the method and not somewhere inside. But this was enough for me to see that there's probably a bug in the Oracle JDBC driver
