I made yet more changes to my package of elisp functions for helping with java editing in emacs. This set adds a function to insert log4j debugging messages into the code.

The formatting of the inserted code is controlled by the java mode so it should end up looking the same as the stuff you write by hand. You can change logCat to some other value by modifying the value of the java-log4j-statement variable. For example:

if (logCat.isDebugEnabled())
    logCat.debug("a" +
                 b);

Here's the code for downloading and for easy reading in a browser.
