Hi Chandra, as indicated in my last mail, you'll need to invest some more time with the BaseX sources. I assume you are creating several instances of the Context instance via the default constructor. Its documentation states that this is only allowed once in the lifetime of a project [1].
If you want to take this further, you could have a look into the ClientListener [2] or LocalSession [3] classes, which are passing on a central Context instance. You could also check out the JUnit testing code in the basex and basex-tests directories.
