I've developed an ear-file which uses and older version of xerces than the one supplied with JBoss 4.0.2. When I call the method that uses xerces I get the following error:
java.lang.NoSuchMethodError: org.apache.xerces.parsers.DOMParser.startDocument()V com.accelio.ces.xmlapi.FSXMLConfig.CreateRequest(FSXMLConfig.java:57) com.accelio.ces.xmlapi.SoapClient.publish(SoapClient.java:81) FormServer.CreateForm.doProcess(CreateForm.java:77) FormServer.CreateForm.doPost(CreateForm.java:27) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)
