Are there any tools that can be given a classpath or folder, and will search through all the .jar files looking for references to a particular class?
It would have saved me a day of searching in order to resolve this kind of problem.
In my case I had to find out where a rogue reference to a class was coming from, as it was stopping JBoss from starting correctly due to a NoClassDefFoundError. I suppose I am looking for this:
java -jar magicbullet.jar /path/to/search com.myproject.DodgyClass
Searching...
com.problematic.Otherclass in /path/to/search/dodgy.jar implements com.myproject.DodgyClass
Or similar. If not, I'll write one.

jar file. Use the -verbose:class option to find class-level dependencies or use the -v or -verbose option to include dependencies from the same JAR file. Use the -R or -recursive option to analyze the transitive dependencies of the com.
the executable jar should NOT contain the dependencies, just enough of your own code to run, with the dependent classes coming from the before mentioned classpath set up in the manifest.
DESCRIPTION. The jar tool combines multiple files into a single JAR archive file. jar is a general-purpose archiving and compression tool, based on ZIP and the ZLIB compression format. However, jar was designed mainly to facilitate the packaging of java applets or applications into a single archive.
Use Tattletale - http://www.jboss.org/tattletale. It helps you create an index which is very handy to search for classes etc.

Under Linux (or Cygwin on Windows) you may use script from https://gist.github.com/980697.
Usage: findclass.sh <directory> <className>
Example: findclass.sh . ClassName (means "search for class named ClassName inside all jars/wars/ears/sars located within current directory and all its subdirectories")
