PicketLink: java.lang.LinkageError during loading javax.xml.crypto.dsig.XMLSignContext -------------------------------------------------------------------------------------- Key: WFLY-1969 URL: https://issues.jboss.org/browse/WFLY-1969 Project: WildFly Issue Type: Bug Components: Web Services Affects Versions: 8.0.0.Alpha4 Reporter: Alessio Soldano Assignee: Derek Horton Fix For: 8.0.0.Beta1 A linkage error javax.xml.crypto.dsig.XMLSignContext is thrown when a XMLSignatureFactory is first resolved by PicketLink (instead of the WS subsystem) on WFLY. This should be fixed by tuning the module dependencies in org.picketlink module, either by modifying the relative order of org.apache.santuario.xmlsec and javax.api modules, or -better by setting an exclude block as follows: {noformat} ... <module name="org.apache.santuario.xmlsec"> <imports> <exclude path="javax/*"/> </imports> </module> ... {noformat}
