Subject [jira] Commented: (AXIS2-3892) WebServiceStub crashes with NullPointerException when web service function is called with null as argument
Date Fri, 04 Jul 2008 15:57:49 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-3892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12610610#action_12610610
] 

Thomas Poetter commented on AXIS2-3892:
---------------------------------------

To be complete: In the function 
private org.apache.axiom.soap.SOAPEnvelope toEnvelope(org.apache.axiom.soap.SOAPFactory factory,
		InterActiveRequest param, boolean optimizeContent) throws org.apache.axis2.AxisFault {
this call leads to the crash because param (= null) is dereferenced:
    emptyEnvelope.getBody().addChild(param.getOMElement(InterActiveRequest.MY_QNAME,	factory));

NullPointerException

> I know that one fix is to prevent the client to call the service with null as argument.
However, I feel the client shouldn't crash in this case but return null without crashing or
throw an IllegalArgumentException or a similar - less fatal and more meaningful exception
than NullPointerException.
