Any luck with jEdit?

I thought I'd try downloading jEdit and let the Plugin Manager do the work of downloading and installing the various plugins. The plugin I really would like to get to work is the CodeAid plugin.
What do I need to do in order to get CodeAid to work? I open an existing java source file and start making modifications and either nothing happens when I type the "." or choose the "CodeAid > Complete" menu item, or I get various compilation error messages about Strings.
I'm obviously missing something here. Any ideas?
Or should I scrap this IDE and get a better one?

for the codeAid plugin to work you need to configure the Jane plugin ( a dependancy of CodeAid )
Jane is the equivalent of libraries in other IDE's
