    Anyone know of a tool that can do this.

    Let's say I have 100 JAR's in various subdirectories. I'm looking for a class and I know the full import name. Is there a tool that will taking that information tell me what jars have that class in it (with the correct package path).

    You can use a normal search.

    In windows:

    search for all *.jar files containing text "packagePath/x.class"

    In unix use find/locate and grep.

    That should work Hobbes - a Jar being a glorified ZIP file, and having an internal directory structure to match the qualified class name.

    If you open any zip file, you'll find a fairly readable chunk at the top.

    There must be an easier way to do it though....

    Download pkunzip.exe

    copy it to where your jars are

    type in dos box

    pkunzip *.jar com\my\package\MyClass.class -t

    and it'll tell you where it found it (-t for test)
    That or just do a text search on the .jar files with any text search (the windows search for files containing text works .. )

    Anyhow .. thats that ;)
