Sometimes, you may encounter problems like this which slows the deployment process.

One option to workaround this issue is add

"-Djavax.xml.stream.XMLInputFactory=weblogic.xml.stax.XMLStreamInputFactory"

to your WebLogic start script. It will prevents WebLogic to fetch any remote xml definition files.
