This  doesn't  look  related to jCIFS. You're getting a name service lookup
failure  and  the VM is not catching a signal. Looks like you might need to
specify a property or two or the VM/Tomcat/JBuilder is crapping out. Try it
with  a different VM or servlet container and take JBuilder out of the loop
if you can. That will allow you to identify where it's choking.

A  program should be written to model the concepts of the task it
performs rather than the physical world or a process because this
maximizes  the  potential  for it to be applied to tasks that are
conceptually  similar and more importantly to tasks that have not
yet been conceived.
