I was getting tired of having problems when building Java apps that required a certain library to be on the classpath or imported into the current app. Another site on the net had a simple lookup mechanism, but that site has gone to a paid subscription model. That just seems silly.
The idea is if you get a compiler error like this:
Exception in thread “main” java.lang.NoClassDefFoundError: javax/wsdl/OperationType
You can just go to JarIndex, enter ‘javax/wsdl/OperationType’, and JarIndex will tell you what library that class comes from. Add it to your classpath, and you’re back into happy compilation mode!
If you program in Java, check it out, let me know if there’s anything missing!
