Error with registering a RESTeasy Providerfactory

[damienmc3]

Hi,

I get the following error:

java.lang.ClassCastException: com.sun.jersey.server.impl.provider.RuntimeDelegateImpl cannot be cast to org.jboss.resteasy.spi.ResteasyProviderFactory
 at org.jboss.resteasy.spi.ResteasyProviderFactory.getInstance(ResteasyProviderFactory.java:330)

After I run this code:

package de.webshop.test.util;

import org.jboss.resteasy.plugins.providers.RegisterBuiltin;
import org.jboss.resteasy.spi.ResteasyProviderFactory;

public abstract class RegisterResteasy {
 private static boolean registered = false;

 public static void register() {
 if (!registered) {
 ResteasyProviderFactory resteasyProviderFactory = ResteasyProviderFactory.getInstance();
 RegisterBuiltin.register( resteasyProviderFactory );
 registered = true;
 }
 }
}

What can be the reason ? Thanks for help in advance.

You are mixing Jersey and RESTEasy.
