Dear All!

I’m writing a business method of an entity bean which is supposed to read some informations from an XML file. I use the following code:

To get the parser and the document:

            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document doc = builder.parse( xmlFile );
    

Then to get the informations I use:

NodeList nl =  doc.getElementsByTagName( tagName );
            int elemCount = nl.getLength();
            for( int i = 0; i < elemCount; i++ )
            {
                Element element = ( Element )nl.item( i );
                String test = element.getTextContent();
               (...)
            }

    

And I get the folowing exception:

org.jboss.tm.JBossTransactionRolledbackException: Unexpected Error
java.lang.NoSuchMethodError: org.w3c.dom.Node.getTextContent()Ljava/lang/String;
    at levia.messages.ejb.MessageTypeBean.requiredInformations(MessageTypeBean.java:345)

    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
    at java.lang.reflect.Method.invoke(Method.java:585)
    

The problem is that outside Jboss this works perfectly. So I guess the problems comes from the fact that jboss uses xerces itself and it configures diferently the parser or something like this…

When I write :

                Text tester = (Text) elem.getFirstChild();
               String blalba = tester.getNodeValue();
    

everything works well…. but still I would like to understand what is the couse of problems with the other solution.

kind regards

Karol

PS: I use jboss 4.0 and xerces 2.6.2

Karol,
Have you tried included your xerces JAR in your WEB-INF/lib directory of your project? JBoss’s classloader should pickup that version of Xer for you instead of using it’s own (maybe an older version like 2.5 that didn’t have that method).

I had a very similiar problem – but with Tomcat and not JBoss. I had to change the java that my project was pointing to. If you point to the new java version 1.5 then it works fine our project is using an older version of java – I had to create a new method that did the same thing as getTextContent does that returns the nodeValue which is the same as the textContent.

Thanks,

unfortunatelly none of your advices worked.

Changing the jboss’es xerces jar’s to 2.7.0 has solved the problem.

kind regards
