Subject Re: java.lang.NullPointer exception when invoking XSDHelper.INSTANCE
Date Fri, 18 Aug 2006 18:46:00 GMT
you are right I do have sdo-api-1.0-SNAPSHOT.jar in the build path of my 
TestCase Java project (which contains my test client).This project depends 
on TuscanySDO project which contains all the source code for SDO 's.(which 
I extracted from SVN)Therefore I did not put the sdo-impl jar in build 
path.By the way by sdo-impl jar did you mean 
tuscany-sdo-impl-1.0-SNAPSHOT.jar?

Re: java.lang.NullPointer exception when invoking XSDHelper.INSTANCE






Looks like you have sdo-api jar in ClassPath, what about sdo-impl jar?
