[jira] Updated: (AXIS-1674) NullPointerException on WebLogic81
[ http://nagoya.apache.org/jira/browse/AXIS-1674?page=history ]
Dominik Kacprzak updated AXIS-1674:
-----------------------------------
Attachment: AXIS-1674.tar.gz
As Dims noticed earlier, this issue is caused by a weblogic.xml.jaxp.RegistryDocumentBuilder not allowing for null values to be passed to setEntityResolver. The attached patch adds a few more catch statements along the lines of what Dims already did. I also added log.debug to the catch statements.
With my patch, I was able to access ?wsdl URLs, deploy/undeploy and use a few sample applications. All tests pass.
My environment:
- WL: WebLogic Server 8.1 SP3
- Java: BEA WebLogic JRockit(TM) 1.4.2_04
- OS: Linux Fedora 3: 2.6.9-1.681_FC3
On a side note, Axis 1.2 does not work out of the box on Weblogic 8.1 due to a conflict between classes in Axis saaj.jar and Weblogic's webservices.jar. I documented this issue and the configuration changes required to get Axis to work on Weblogic in a README file included with my patch. This should be documented somehow in Axis 1.2 release notes and/or in a wiki. If my README file does not provide sufficient information, please let me know.

Can somebody with access to CVS review and apply my patch? We will have one less blocking issue:)
