Error while calling invokeMethod

What could be the problem?

invokeMethod(op,        
  "write",        
  inArgs,         //input argument array -> Passing a string
   null);

And waht could be the reason for this exception?

java.io.IOException

When you are talking about Java Reflection, this is irrelevant. You can't pass an argument of 4000 bytes to a method. The maximum you can pass is 8 bytes. Because of this is the size of the biggest datatypes in Java: long, double. Even an array is 4 bytes, because of it is an Object, which is represented by a memory pointer.

So, I think you have to search your problem somewhere else...
