Hi,
NullPointerException is thrown when the application try to access to java object but it is null or not present.
From the stacktrace you dump, it shows that bchome.jsp try to access to null object on the line of code 269.
If this jsp is simple, you can guess what variable is null and try to fix and test.
If it's quite complex, you should find the class after jsp complied _chome.java which will be on staging folder of weblogic when you do deployment.
Hope this help,
Sompol
