Well, tomcat is telling you where the program fails:
java.lang.NullPointerException
 at jsp.sanjamar.test.CatMan.SelectSubCategories(CatMan.java:110)
 at jsp.sanjamar.test.CatMan.ListSubCategories(CatMan.java:54)

Unfortunately, from your previous post, I have no idea what line 110
of CatMan.java is, nor do I know which line corresponds to #54. Some
operation is being performed on a NULL object. Look at these two
lines and the problem will probably become obvious. It's likely a
logic problem, not a server configuration issue.
