[jira] Created: (AXIS2-3276) Null pointer exception while doing
wsdl get using useOriginalWsdl option. Reason : underlying definitiion is
not threadsafe
Null pointer exception while doing wsdl get using useOriginalWsdl option. Reason : underlying definitiion is not threadsafe
---------------------------------------------------------------------------------------------------------------------------
Key: AXIS2-3276
URL: https://issues.apache.org/jira/browse/AXIS2-3276
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: wsdl
Affects Versions: 1.2
Environment: HP UX
Reporter: Haneef Ali
Priority: Critical
I'm seeing Nullpointer exception during wsdl fetch. My webservice is created using "useOriginalWSDL=true" option.
This happens only during concurrent access. It can be easily reproduced by creating a JMeter test for http get with 5 thread. BTW I'm using Axis 1.2
From google search the reason for this seems to be
" This is because the WSDL handling system reuses javax.wsdl.Definition objects across threads, which are not thread safe, because they internally use DOM elements."

It occured everytime the WSDL was accessed through the ListingAgent.
It seems like the javax.wsdl.Definition is permanently corrupted by these thread issues.

[jira] Commented: (AXIS2-3276) Null pointer exception while doing
wsdl get using useOriginalWsdl option. Reason : underlying definitiion is

------------------------------------
note: adding synchronized to org.apache.axis2.description.AxisService#printUserWSDL *does* fix this issue.

Carsten Lohmann commented on AXIS2-3276:
----------------------------------------
To me, it looks like this issue is not resolved in the current version.
In
org.apache.axis2.description.AxisService#printUserWSDL
it's always the same javax.wsdl.Definition instance that is used:
----
Parameter wsdlParameter = getParameter(WSDLConstants.WSDL_4_J_DEFINITION);
if (wsdlParameter != null) {
definition = (Definition) wsdlParameter.getValue();
}
..
printDefinitionObject(getWSDLDefinition(definition, wsdlName), out, null);
----
If this printUserWSDL() method is accessed concurrently by multiple threads, the above problems can occur.
I would suggest adding synchronization to this method.
