[jira] Created: (AXIS2-4871) Null Pointer Exception in
AxisService.printXSD
Null Pointer Exception in AxisService.printXSD
----------------------------------------------
Key: AXIS2-4871
URL: https://issues.apache.org/jira/browse/AXIS2-4871
Project: Axis2
Issue Type: Bug
Components: kernel
Affects Versions: 1.5.2
Environment: Test run on Websphere 6.1 application server
Reporter: John Kroll
For the generic unqualified schema request (for example: http://<host name>/axis2/services/Version?xsd the following exception is thrown:
java.lang.NullPointerException
at org.apache.axis2.description.AxisService.printXSD(AxisService.java:1235)
at org.apache.axis2.transport.http.ListingAgent.processListService(ListingAgent.java:277)
at org.apache.axis2.transport.http.AxisServlet.doGet(AxisServlet.java:249)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:743)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:856)
The problem seems to be related to the fact that for the unqualified case the argument for the schema name is null, not an empty string. Changing the name test in line 1232 of modules/kernel/src/org/apache/axis2/description/AxisService.java to include a null pointer check seems to resolve this issue. Sample change:
< revision
> original
1232,1233c1232
< // Unqualified schema request can be a null string
< if ( (xsd != null) && (!"".equals(xsd)) ) {
---
> if (!"".equals(xsd)) {

Andreas Veithen commented on AXIS2-4871:
----------------------------------------
Can you please explain the steps to reproduce the issue? With a standard Axis2 1.5.2 distribution, http://localhost:8080/axis2/services/Version?xsd doesn't trigger any exception.

-----------------------------------
By unqualified schema I mean by requesting the schema without a name.
For example: Version?xsd as opposed to Version?xsd=SomeName

John Kroll commented on AXIS2-4871:
-----------------------------------
Test environment: Websphere 6.1 Network Deployment, Fix Pack 23 (6.1.0.23) on Windows Server 2003, using the standard Axis2 1.5.2 distribution. HTTP requests are forwarded to the application server by an IBM HTTP Server 6.1.0.31.
Attempting to retrieve an unqualified schema for the Version service (originally found while testing a custom web service, but replicated using the Version web service on the standard Axis2.war) results in the above listed null pointer exception 100% of the time.
