Hi,
I recently incorporated a map into an existing project and I am receiving a null pointer exception when trying to load a wms layer. I found that the project has a dependency on a jar called "xerces.jar". This jar has a resource in it that sets the SAXParserFactory implementation to be org.apache.xerces.jaxp.SAXParserFactoryImpl. When this jar is not included, the SAXParserFactory implementation that is used is com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl and the wms layer loads fine.
I was wondering if anyone has encountered this issue and had a work around. I am unable to remove the dependency from the project.
Thanks.
Here is the stack trace:
