AS7 7.1.1.Final: java.lang.ClassCastException: org.jcp.xml.dsig.internal.dom.DOMXMLSignatureFactory cannot be cast to javax.xml.crypto.dsig.XMLSignatureFactory

Hi again,

Sorry to post a question again, but Im trying to migrate an application to AS 7 and Im getting a lot of errors.

On the JBoss AS 7.1.0 CR1 the above declaration works:

private static XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");

And on the jboss-as-7.1.1.Final doesn´t . I get:

java.lang.ClassCastException: org.jcp.xml.dsig.internal.dom.DOMXMLSignatureFactory cannot be cast to javax.xml.crypto.dsig.XMLSignatureFactory

at com.sun.faces.facelets.el.TagValueExpression.getValue(TagValueExpression.java:114) [jsf-impl-2.1.7-jbossorg-2.jar:]

Any ideas??

Tryed with the latest jboss 7.1.2 and the problem still exists.

to simulate, just add on a method "XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");" or use the static reference on the first example.

This is an issue or I need to import some another module on MANIFEST.MF ?

Can you give an overview of your application's structure? Are you packaging an xml security implementation in your app?

BTW I see problems on our side, I just want to make sure I understand how you are using it.

Sure,

My structure is:

An EJB TimerService that will sign a XML with a digital certificate. All by "scratch". There is no deployment descritors.

The app:

myapp.ear
   lib
       myutilclasses.jar
   myapp.war (some rest services)
       lib
          primefaces.jar
   myapp.jar (Some TimerServices, some Assynchronous EJB invocation and stored procedures calls)

EAR MANIFEST (the others are empty)
Dependencies: org.apache.log4j export,com.nl.ed export,oracle.jdbc export,org.jboss.ironjacamar.jdbcadapters export,javax.mail.api export

On jboss modules (I created my own module) i have some extra libraries:

ojdbc6.jar, barbecue.jar, commons-digester.jar, itext.jar, jasperreports.jar, jasypt.jar, pdfrenderer.jar

But:

Try to deploy an single EJB module on jboss as7 with this class, and the problem will happen:

package TesteTimer;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import javax.ejb.ScheduleExpression;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.ejb.Timeout;
import javax.ejb.TimerService;
import javax.xml.crypto.dsig.XMLSignatureFactory;

@Singleton
@Startup
public class TimerClass {
    @Resource
    TimerService timerService;

    @PostConstruct
    public void initialize() {
        ScheduleExpression expression = new ScheduleExpression();
        expression.second("*/1").minute("*").hour("*");
        timerService.createCalendarTimer(expression);
    }

    @Timeout
    public void execute() {
        System.out.println("BEFORE EXCEPTION");
        XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");
        System.out.println("AFTER EXCEPTION");
    }
}

Thansk for your help!

I have same exception on jas 7.1.1 final.

Artifacts buided as jar (EJB3), running with jdk 1.6.0_31.

Did you find any solution?

Thanks a lot

fuinhaazul Mar 21, 2012 7:28 AM (in response to giama)

Yes

The solution was fallback to AS6.1 ....

For my project AS 7.1 has 2 major problems that make impossible to use (see my other post about server shutdown) .

Maybe later I will open an jira and post the link here.

giama Mar 21, 2012 7:36 AM (in response to fuinhaazul)

i can't fallback...

i'm porting a project from jboss 4.2.3 to as7.. it's very very hard to do... i solved several problem. i can't believe this classcast is unsolvable... it's just a classcast...

i just tried to cast to new class the getInstance statement

org.jcp.xml.dsig.internal.dom.DOMXMLSignatureFactory signatureFactory = (org.jcp.xml.dsig.internal.dom.DOMXMLSignatureFactory) XMLSignatureFactory.getInstance("DOM");

who tried this? i'm getting same exception.. but i think it's impossible.. what's wrong?

What would help us to resolve your problem is to post the details of your application structure.

Also if would help if you could set a ClassCastException breakpoint in your IDE, and report the two different class loaders that are causing the problem(i.e. the expected class loader and the actual class loader).

What application details do you need Stuart?

This is the stack trace

I saw that XMLSignatureFactory.java:202 doesn't correspond to correct line to XMLSignatureFactory contained into running JVM rt.jar. Seems to me that jboss runtime use the one contained into module org\apache\santuario\xmlsec. This module contains xmlsec-1.5.1.jar: is this a stable version?

giama Mar 21, 2012 9:49 AM (in response to giama)

i think i solved...

but not in a canonical approach and i hope a patch will be done...

i replaced xmlsec-1.5.1.jar with the previous version xmlsec-1.4.6.jar and correct relative module.xml in org\apache\santuario\xmlsec\main and now it works.

Seems to me that last santuario has something wrong: anyone know something about?

There's been some refactoring in Santuario 1.5 which imply changes to be applied on the JBoss AS modules. See pull request in AS7-4248.

Hi,

Is this problem solved? I have the same problem whit JBoss 7.1.1.

java.lang.ClassCastException: org.jcp.xml.dsig.internal.dom.DOMXMLSignatureFactory cannot be cast to javax.xml.crypto.dsig.XMLSignatureFactory

Is the approach of downgrade the xmlsec module to xmlsec-1.4.6.jar ?
