Invoking multiple methods which are exposed using Axis

I am trying to create a service ticket, calling the methods (login, createTicket, logout) from Eclipse IDE. I had called the method login(), by passing uid, pwd, and got SID wh开发者_开发技巧ich is a session ID, in return. Now I am trying to create a ticket, and I am passing all the required params.

Error that I got is:

DEBUG [main] (Call.java:2445) - NSPush (32)
DEBUG [main] (Call.java:2445) - org.apache.axis.i18n.resource::handleGetObject(empty00)

Help needed regarding this!

Well, I tried the same method by giving only the required parameters, and it had worked. The other optional parameters take some pre-defined set of value, which, when not given, raises the error.
