RE: navigate through big java projects and refactoring

["Drew Adams" <drew.adams@oracle.com>]

    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

Try Icicles. It lets you match (using a regexp or just a literal substring)
any part of a file name. You can optionally match also against any part of a
directory path. You can use multiple simple match patterns to progressively
narrow the set of matching candidates, so you don't need to come up with a
single, complex regexp that will do what you want. You can use set
operations on the set of matching candidates - in particular, set
complement, to more easily get what you want. You can perform actions on
multiple files and directories, all within the same command. You can save
sets of completion candidates (e.g. project files and directories) in cache
files for quick use in subsequent sessions. You can easily work with very
large sets of candidates. Lots more. And the same completion features are
available for buffers, commands, anything - not just files.

Here is the complete doc and access to the Emacs-Lisp files:

can help with navigating the file system:
