If you have access to Oracle support, you should read the document 1416001.1 & 1274889.1. These two documents show you step by step on how to debug/run a provider BSSV locally. It took me about 2 hours to make it work for the first time.
1) You need to start IntegratedWebLogicServer (You start this in JDeveloper)
2) You need to deploy your BSSV to IntegratedWebLogicServer
3) You call your BSSV method from IntegratedWebLogicServer
