NullPointerException in DocumentBuilderFactoryImpl
--------------------------------------------------
Key: WSCOMMONS-210
URL: https://issues.apache.org/jira/browse/WSCOMMONS-210
Project: WS-Commons
Issue Type: Bug
Components: AXIOM
Environment: Axiom 1.2, Axis2 1.1, JRE 1.4.2, Tomcat 4.1.30
Reporter: Johan Roch
We have a webapp with some Axis2 clients. Axis2 uses Axiom to handle xml.
Other parts of the application parse some XML documents.
After some time, our webapp starts to use the Axiom DocumentBuilderFactory
everywhere(instead of Xerces) and we get some NullPointerException each
time in Axiom:
Example with JasperReport:
