when i passed HashMap object in invokeRobust i am getting always OMException:NullPointerException ...
for example:
<code>

UserCl ob=new UserCl();
HashMap<String,Object> hm=-new HashMap<Object,Object>;
hm.put<"KEY","value">;
ob.setHM(hm);
QName opSetQuiz = new QName("http:xsd","submitUsedata");
Object[] opSetQuizArgs = new Object[] {ob};
client.invokeRobust(opSetQuiz, opSetQuizArgs);
<code>
