I reviewed the building of the jars files for the various SDKs and the original script I created did not properly build with the proper names. I'm still not sure if this is correct, since the ant build.xml and web page do not appear to correspond.
The file is attached if you still wish to use it. I'm sorry for not properly reviewing the requirements of the various required names for the builds. I left the source creation the same for now.
Again if SDK 1.7 & 1.8 are both present then the result jdbc41 jar will be the build from 1.8. Perhaps this should be checked and left with the lower build jar file if present.
