navigate through big java projects and refactoring

[op132650c]

Hi,

I want to work with emacs for programming Java. Is there any other way then
using the speedbar and ECB program, to open files easily from a big project,
instead of having to write the full path to the source file, or navigate
through project browser of ECB? Something like, only have to write the full, or
partial name of the java file, and open it.

Is there any other refactoring tool for emacs, instead of ECB?

Thanks,
Pedro
