Hi *, I know, I'm going to open a second topic on this, although there's already a similar problem posted here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110298#.... However, in my case I'm using the opposite direction. I've set up a webservice using an underlying EJB(3) for the implementation. The SEI contains only one method, which uses a message that was compiled before from various schemas (containing UBL2,e-GIF) by using JAXB2.1. Once that webservice is deployed on JBoss he is trying to map all these classes back to XSDs and I receive the same NPE: | java.lang.NullPointerException | at org.jboss.ws.metadata.wsdl.xmlschema.JBossXSEntityResolver.getXMLInputSource(JBossXSEntityResolver.java:167) | at org.jboss.ws.metadata.wsdl.xmlschema.JBossXSEntityResolver.resolveEntity(JBossXSEntityResolver.java:135) | at org.apache.xerces.impl.XMLEntityManager.resolveEntity(Unknown Source) | at org.apache.xerces.impl.xs.XMLSchemaLoader.resolveDocument(Unknown Source) | at org.apache.xerces.impl.xs.traversers.XSDHandler.resolveSchema(Unknown Source) | at org.apache.xerces.impl.xs.traversers.XSDHandler.constructTrees(Unknown Source) | at org.apache.xerces.impl.xs.traversers.XSDHandler.parseSchema(Unknown Source) | .... | I'm using JBoss4.2.2GA. Is this bug already confirmed? I'm going to try to work around this problem by using a WSDL generated by wsprovide and doing wsconsume on it to receive the necessary interfaces for the implementation, but if that is really working, it's not a nice way of solving this issue. Any help is highly appreciated :) Thanks, Max View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124794#...
