Obtaining method parameter names from compiled class files

For java source compiled with the debug option (-g), the class files contain the method paramter names. However these are not available via Reflection. Does anyone know of a way to get these? Does JavaAssist or BCEL provide such a facility? I had a quick look at JavaAssist API and could not find a way.

I need the paramter names for a custom WSDL creation from Java Source files for Web Services development. I would like the WSDL parameters to be something meaningful rather than generic param1, param2, etc. I know that Web Service engines like Axis do the exact same thing, probably via class file parsing, which I would hate to do on my own.

Since you have the Java source files, it might be easier to extract the information from that.

Decompilers like Jode (on SourceForge) obviously can do this. It tmight be worth a look if that capability is accessible through an API.

Yes, with -g the method parameter names are available. I'm going to bet that this information is available through BCEL - I'd be surprised if not.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
