    java.lang.VerifyError Exception

    sachin singhal Newbie

      Hi,

      I am trying to create a simple XML by calling createElement function from a stateless session bean. below is the code of createElement .

      public Element createElement() {
      XMLParserLiaison xpl = new XercesParserLiaison();
      Document doc = xpl.createDocument();
      Element el = doc.createElement("SessionID");
      el.appendChild(doc.createTextNode(sessionid != null ? sessionid.toString() : ""));
      return el;
      }


      I am using JBoss to deploy the EJBs. When I try to access the EJB from the client, I get the java.lang.VerifyError exception. Please let me know if anyone has any idea about this exception.

      Unexpected Error
      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
