JBoss EAP 6.2 Performance Testing

Latest response

When we tried to run 30 requests per second from a Netty server to Stateless Session EJB in JBossEAP 6.2 we get the following exception randomly.
And from internet we came to know that it is known bug. Is it resolved in JBossEAP6.2 or is there any work around for this?

Could you show the client code how you access the SLSB?

Hello Fink,
Here is the client code to access the EJB:

final String appName = "";
final String moduleName = "MYEJB";
final String distinctName = "";
final String beanName ="MYBean";
final String viewClassName =MYRemote.class.getName();
Properties jndiProps = new Properties();
jndiProps.put(Context.PROVIDER_URL, "remote://");
jndiProps.put(Context.SECURITY_PRINCIPAL, );
jndiProps.put("jboss.naming.client.ejb.context", true);

        // create a context passing these properties
        Context ctx = new InitialContext(jndiProps);
        // lookup the bean Remote
        MYRemote myBean = (MYRemote) ctx
                .lookup(appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);

    } catch(Exception e) {
        throw new RuntimeException();

Thank you for help

This has nothing to do with netty.
You use remote-naming which might have issues.
It is receommended to use the jboss-ejb-client.properties and the related approach for the invocation.

Did you get the solution to this issue.
I am seeing the same ERROR in my application

Hi Wolf-Dieter, I am using the technique you suggested. Still seeing the same error when performance testing.

Hi Jeremy,

sorry, did not saw that earlier. If this is still an issue I would recommend to open a case for this. Also the KCS articles show different approaches and what the drawbacks are.

Hi Guys,

I had same issue, Did you guys have solution for this issue ?

Thanks, Chary

Hi, My advice is to version bump to EAP 6.4 and re-test. There have been a number of issues resolved in the remoting layer since 6.2. Release Notes:

6.3 https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.3/html/6.3.0_Release_Notes/Changes_in_This_Release.html#idp12410832

6.4 https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.4/html/6.4.0_Release_Notes/sect-Resolved_and_Known_Issues.html#Resolved_Issues

Regards, Jeremy

Hi, I am getting similar issue for Jboss 6.4.5 version. Did anyone find the solution for this issue ?

Thanks , Manish
