Error description
Error Message: Received 'java.net.UnknownHostException' while running a java program as a batch job on Z/OS. This error occurs only when the job is run by some users. Typically the Users involved either do not have a home directory defined, or have their home directory set to '/' (root) or "" (empty string) or some other invalid location. .

Local fix
z/OS Users wishing to run Java applications typically require a writable home directory. One should be created to avoid this particular XML Resolver problem.
Problem summary
On z/OS it's possible for the value of user.dir to be ".", "/" or "". The XML catalog resolver in XML4J doesn't tolerate any of these values very well and will print the stack trace of an exception to System.err when the resulting URL cannot be read. Since the exception is printed to System.err customers (like this one) may see it in a log and be alarmed about it.
Problem conclusion
This defect will be fixed in: 6.0.0 SR10 FP1 6.0.1 SR1 FP1 7.0.0 SR1 . IBM JVM has been updated to correctly handle java.net.UnknownHostException.
Temporary fix
