Java Jar Class Finder

Too many times I've come across sample code that reference classes but doesn't indicate what jar file to reference. Not knowing what jar file a class is in makes this annoyance Number 732 on my list of things I hate about Java.

JarClassFinder.zip 

I wrote JarClassFinder to solve this problem and use it most every day. The application should be fairly obvious:

  1. Point at some folders,
  2. enter a class,
  3. click 'Search

Dave,
I never had a chance to use this tool until Ron's email pointed me to your blog. I had lost the source that you had sent me and was using the older version. However this one is much better. I do have a couple of suggestions that may be would be useful:

1) Advance search options - Sometimes I would get several hits (especially when searching several folders) in my search results and I'd have to expand the list and read each line. Two things that I thought would be nifty while I was using it:
a) Exact string search - this would look for the exact class name maybe with case sensitive option.
b) Wildcard string search - supporting the '*' wildcard character
2) Providing history of passed class name searches. This could be a drop down list in place of the current text field where you enter the class name.

At any rate, good tool and nice blog.

Thanks for the suggestions. I didn't spend too much time on it and actually am still surprised at how useful it's been. If I find the time, I'll look into adding those features.

Thanks again!
