Hello Kevin and Dan,
I have removed the following jar files from $KEPLER/lib/jar/jwsdp.
PackageFormat.jar activation.jar
commons-beanutils.jar commons-collections.jar
commons-digester.jar commons-logging.jar dom.jar
jaas.jar jax-qname.jar jaxp-api.jar jaxrpc-api.jar
jta-spec1_0_1.jar keyexport.jar namespace.jar
pkcs12import.jar relaxngDatatype.jar sax.jar
security-plugin.jar xalan.jar xercesImpl.jar
xsdlib.jar
To make GriddLeS actors work, I have copied jars from jwsdp deployment
in a rush.
Now I checked the above jars are not needed and some of them are
duplication.
Sorry for the inconvenience.
with regards,
Jagan Kommineni
