wildfly invok ejb error: EJBCLIENT000025

[wuqian2huangchangsong]

Hi,

     I got the code in wildfly web.and deploy it to the server.

09:57:28,871 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-7) JNDI bindings for session bean named CalculatorBean in deployment unit deployment "wildflyejb3.jar" are as follows:

     Then I got  the  client code,and jboss-ejb-client.properties

endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

remote.connections=default

remote.connection.default.host=localhost

remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

remote.connection.default.username=wuqian@hcs
remote.connection.default.password=wuqian@891210

     the dir is:

     client

          |--Client.java

          |--jboss-ejb-client.properties

but when I run the client it is error:

what can I do? thanks!

[jaikiran]

You are using a wrong JNDI name in your client code which does the lookup. The JNDI bindings show that the module name is wildflyejb3 whereas you are using wildflyejb as the module name during the lookup (that's what the stacktrace suggests).

[wuqian2huangchangsong]

Thanks.It is an error.and I user the "wildflyejb3",the error can not be fixed. Sorry for my English.

I dot know why?but thanks!

[wdfink]

I don't see the client code in your post.

Also how do you start the server?

[wuqian2huangchangsong]

thanks! I have fixed it.

but I not know why?

my client code is the jboss web code:

public class RemoteEJBClient {
    public static void main(String[] args) throws Exception {
        invokeStatelessBean();
        invokeStatefulBean();
    }

    private static void invokeStatelessBean() throws NamingException {
        final RemoteCalculator statelessRemoteCalculator = lookupRemoteStatelessCalculator();
        System.out.println("Obtained a remote stateless calculator for invocation");
        int a = 204;
        int b = 340;
        System.out.println("Adding " + a + " and " + b + " via the remote stateless calculator deployed on the server");
        int sum = statelessRemoteCalculator.add(a, b);
        System.out.println("Remote calculator returned sum = " + sum);
        if (sum != a + b) {
            throw new RuntimeException("Remote stateless calculator returned an incorrect sum " + sum + " ,expected sum was " + (a + b));
        }
        int num1 = 3434;
        int num2 = 2332;
        System.out.println("Subtracting " + num2 + " from " + num1 + " via the remote stateless calculator deployed on the server");
        int difference = statelessRemoteCalculator.subtract(num1, num2);
        System.out.println("Remote calculator returned difference = " + difference);
        if (difference != num1 - num2) {
            throw new RuntimeException("Remote stateless calculator returned an incorrect difference " + difference + " ,expected difference was " + (num1 - num2));
        }
    }

    private static void invokeStatefulBean() throws NamingException {
        final RemoteCounter statefulRemoteCounter = lookupRemoteStatefulCounter();
        System.out.println("Obtained a remote stateful counter for invocation");
        final int NUM_TIMES = 20;
        System.out.println("Counter will now be incremented " + NUM_TIMES + " times");
        for (int i = 0; i < NUM_TIMES; i++) {
            System.out.println("Incrementing counter");
            statefulRemoteCounter.increment();
            System.out.println("Count after increment is " + statefulRemoteCounter.getCount());
        }
        System.out.println("Counter will now be decremented " + NUM_TIMES + " times");
        for (int i = NUM_TIMES; i > 0; i--) {
            System.out.println("Decrementing counter");
            statefulRemoteCounter.decrement();
            System.out.println("Count after decrement is " + statefulRemoteCounter.getCount());
        }
    }

    private static RemoteCalculator lookupRemoteStatelessCalculator() throws NamingException {
        final Hashtable jndiProperties = new Hashtable();
        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        final Context context = new InitialContext(jndiProperties);
        final String appName = "";
        final String moduleName = "jboss-as-ejb-remote-app";
        final String distinctName = "";
        final String beanName = CalculatorBean.class.getSimpleName();
        final String viewClassName = RemoteCalculator.class.getName();
        return (RemoteCalculator) context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);
    }

    private static RemoteCounter lookupRemoteStatefulCounter() throws NamingException {
        final Hashtable jndiProperties = new Hashtable();
        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        final Context context = new InitialContext(jndiProperties);
        final String appName = "";
        final String moduleName = "jboss-as-ejb-remote-app";
        final String distinctName = "";
        final String beanName = CounterBean.class.getSimpleName();
        final String viewClassName = RemoteCounter.class.getName();
        return (RemoteCounter) context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName + "?stateful");
    }
}

and I delete the jboss-ejb-client.properties

change the Underline code:  --------------------it work!

Properties clientProperties = new Properties();
        clientProperties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
        clientProperties.put("remote.connections", "default");
        clientProperties.put("remote.connection.default.port", "8080");
        clientProperties.put("remote.connection.default.host", "localhost");
        //clientProperties.put("remote.connection.default.username", "ejb");
        //clientProperties.put("remote.connection.default.password", "wuqian@891210");
        clientProperties.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
        EJBClientContext.setSelector(new ConfigBasedEJBClientContextSelector(new PropertiesBasedEJBClientConfiguration(clientProperties)));
        Properties properties = new Properties();
        properties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        final Context context = new InitialContext(properties);

user and password are not must!!!

[wdfink]

Yes that is a different approach.

If oyu use the quickstart as is it should work.

As long as you run on the same host and have access to the servers directory the LOCAL option is used for authentication by default.

See documentation

[wuqian2huangchangsong]

Thanks very much!

But why does not it  work for the "jboss-ejb-client" method?

This is my "jboss-ejb-client.properties":  and I take it in the same package with the client class. Sorry for my English -:)

1. endpoint.name=client-endpoint 
2. remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false 
3.  
4. remote.connections=default 
5.  
6. remote.connection.default.host=localhost 
7. remote.connection.default.port = 8080 
8. remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false 
9.  
10. remote.connection.default.username=wuqian@hcs 
11. remote.connection.default.password=wuqian@891210 

[wdfink]

I think that is your problem.

You should not pack the properties in a package, simple use the root directory of the classpath
