java.lang.VerifyError Exception
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
