Description

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:

< // Unqualified schema request can be a null string
< if ( (xsd != null) && (!"".equals(xsd)) ) {
—
> if (!"".equals(xsd)) {
