Migrate from Jboss 4.2.3 to Wildfly 8

Question

I'm trying to migrate a very old java application from Jboss 4.2.3 to Wildfly 8. I just installed the Wildfly server and the minimal config things.

In my App, my JNDI.properties file was :

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

So I updated it to simply :

java.naming.factory.url.pkgs=org.jboss.ejb.client.naming

The code which call the EJB was :

Properties ht = new Properties();
ht.load(BIServicesImpl.class.getClassLoader().getResourceAsStream("jndi.properties"));
Context context = new InitialContext(ht);
return (ServiceEntryPoint) context.lookup("BIServeurMetier/ServiceEntryPointBean/remote");

The JNDI path have changed in Wildfly 8 so I used :

Properties ht = new Properties();
ht.load(BIServicesImpl.class.getClassLoader().getResourceAsStream("jndi.properties"));
Context context = new InitialContext(ht);
return (ServiceEntryPoint) context.lookup("BIServeurMetier/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint"); 

I deploy my application war into it, and start it, it runs pretty well :

2022-06-27 16:21:00,773 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-3) JNDI bindings for session bean named ServiceEntryPointBean in deployment unit subdeployment "BIServeurMetier.jar" of deployment "BIServeurMetier.ear" are as follows:

    java:global/BIServeurMetier/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:app/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:module/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:jboss/exported/BIServeurMetier/BIServeurMetier/ServiceEntryPointBean!com.al6.bi.business.ServiceEntryPoint
    java:global/BIServeurMetier/BIServeurMetier/ServiceEntryPointBean
    java:app/BIServeurMetier/ServiceEntryPointBean
    java:module/ServiceEntryPointBean

So the EJB seams to be fine and deployed. But when I try to do any action on the app, I have this error :

The path of EJB seems to be good because it is displayed at the beginning of the server log when the server starts. So what I'm doing wrong ?

I also check via the management console in JNDI, my EJB are here and listed.

Answer 1

JNP is the old JNDI implementation, you need to update your jndi.properties. I think that for WildFly 8 it is : final Properties env = new Properties(); env.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.naming.remote.client.InitialContextFactory.class.getName()); env.put(Context.PROVIDER_URL, "remote://localhost:4447"); remoteContext = new InitialContext(env);

Answer 2

In addition to ehsavoie answer, I needed to trick a few things to make it works.

I follow the tutorial here :

https://docs.jboss.org/author/display/WFLY10/EJB%20invocations%20from%20a%20remote%20client%20using%20JNDI.html

And here :

https://docs.jboss.org/author/display/WFLY10/Remote%20JNDI%20Reference%20Update%20Draft.html

In fact, in my case, I don't need http remoting mode, just a simple EJB mode, so no complex parameters to put in JNDI.properties.

I delete my jndi.properties file, and just update the code to :

final Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
final Context context = new InitialContext(jndiProperties);
return (ServiceArchiveEntryPoint) context.lookup("ejb:BIServeurMetier/BIServeurMetier//ServiceArchiveEntryPointBean!com.al6.bi.business.ServiceArchiveEntryPoint");

In my first tries before that code, it doesn't work. I think it was because I don't put the correct path. The rule seems to be :

context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);

Before that, I don't put a "distinctName", but it seems that if we don't have one, just put a empty string, so it gives in my case "//".

Maybe it was that, maybe it was the "ejb:" prefix, I don't know which change make it works, but it works now.
