No matching XNIO provider found

[paolo.barberis.73]

Hi everybody,

I'm trying to call an EJB deployed on JBoss 6.3 EAP, from an external jar (basically it is a batch running outside of JBoss).

I put in the lib directory of jar and also in MANIFEST of jar the xnio-api and xnio-nio jars.

But at runtime, when I make the call I always get the:

java.lang.IllegalArgumentException: No matching XNIO provider found

[jaysensharma]

the "jboss-client.jar"  which you will get from "jboss-eap-6.3/bin/client"  already contains all the  XNIO related stuff which are needed for the client, So you should not try to include the  "xnio-nio-3.0.0.GA.jar" or "xnio-api-3.0.0.GA.jar" APIs separately on the client classpath.  Try removing those jars from client classpath.

Can you also let us what kind of ejb client code are you using ?

[jaysensharma]

Can you please post the complete stackTrace?

Also are you using Spring Based EJB Client?   It also looks like you are getting the xnio JARs from outside (community jar) where as this jar is also offered by JBoss EAP

So if you really want to use this jar then  add "xnio-nio-3.0.10.GA-redhat-1.jar" jar in the client classpath. This jar is usually present inside "jboss-eap-6.3/modules/system/layers/base/org/jboss/xnio/nio"

For maven based project this JAR can be retrieved from: https://maven.repository.redhat.com/techpreview/all/org/jboss/xnio/xnio-nio/3.0.10.GA-redhat-1/

I tried to:

• remove both jars --> same exception
• put ONLY the specific EAP jar --> same result

Some more details:

the call is made like this:

LookupUtil.lookup(EjbRemote.class,EjbRemote.JNDI_NAME).doSomething();

The EjbRemote class is:

import javax.ejb.Remote;

@Remote
public interface EjbRemote {

    public static final String JNDI_NAME = "ejb:services/server-ejb/server/EjbRemoteBean!com.xxx.services.ejbserver.EjbRemote";
    void doSomething();
}

and the look method from my utility class is:

public static <T> T lookup(Class<T> clazz, String jndiName) {
        Object bean = lookup(jndiName);
        return clazz.cast(PortableRemoteObject.narrow(bean, clazz));
    }
   
    public  static Object lookup(String jndiName) {
        Context context = null;

        Properties props = new Properties();
        props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");


        try {
            context = new InitialContext(props);
            if ( JBOSS_RUNS_STANDALONE && jndiName.startsWith( "ejb:" ) ) {
                jndiName = removeServerGroupFromJNDI( jndiName );
            }
            return context.lookup(jndiName);
        } catch (NamingException ex) {
            throw new IllegalStateException(String.format("Can't lookup bean '%s'", jndiName), ex);
        } finally {
            try {
                if (context != null) {
                    context.close();
                }
            } catch (NamingException ex) {
                throw new IllegalStateException("Can't close InitialContext", ex);
            }
        }
    }

    private static String removeServerGroupFromJNDI( String jndiName ) {
        String [] parts = jndiName.split( "/" );
        if( parts.length != 4 ) {
            throw new IllegalArgumentException( "JNDI name should be in format: \"ejb:ear-name/jar-name/distinct-server-name/BeanName!InterfaceName\". The given jndi name is: " + jndiName );
        }
        String jndiWithoutServerGroup = parts[0] + "/" + parts[1] + "//" + parts[3];
        return jndiWithoutServerGroup;
    }
