How to package a version of Xerces in a WAR application in JBoss EAP 5?

Solution Unverified - Updated -

Issue

  • I have an issue with xercesImpl.jar lib provided in EAP 5.0 inside JBOSS_HOME/lib/endorsed/.

  • The customer has a WebApp that invokes a WebService using a specific version of xerces. When app try to access the WS the following error is occuring:

    "root cause
java.lang.VerifyError: (class: org/apache/soap/util/xml/XercesParserLiaison, method: read signature: (Ljava/lang/String;Ljava/io/Reader;)Lorg/w3c/dom/Document;) Incompatible object argument for function call
 org.apache.soap.rpc.Call.<init>(Call.java:85)
 org.apache.soap.rpc.Call.<init>(Call.java:97)
 org.apache.soap.rpc.Call.<init>(Call.java:91)

  • Even with class scoping and jboss-classloading descritptor inside the WAR, this problem occur. The only way that this webapp works is moving the JBOSS_HOME/lib/endorsed/xercesImpl.jar to JBOSS_HOME/lib/.

  • Is there any way to isolate libs provided by a WAR from JBoss endorsed libs?

Environment

  • JBoss Enterprise Application Platform (EAP)
    • 5.0.1
