  </code></pre>
  
  <p>Can anyone suggest ?</p>
  
  <p>Using <code>java 1.6</code> and <code>axis2 jars</code>.  </p>
  
  <p>I also observered that in one system same code is working fine but in other code is getting this issue. I think this is not coding issue, may be some jar or other issue but not sure. </p>
