Error in Marshal EJB parameters caused by slf4j module not found

[v.stola]

Hello at all,

This is Vincenzo and I am new to the community.

For the first time I'm using a jboss distribution (wildfly 11.0 Final version with JDK 1.8) in order to study the feature of this application server (since it has a good reputation on the web).

As a first project, I have created and deployed two EAR on the server: the first one contains a WAR while the second one contains a EJB. The goal is to perform a simple call to a EJB remote method but a error occurred during the invocation.

The stack trace is the following:

An error is occurred: java.lang.RuntimeException: WFLYEJB0054: Failed to marshal EJB parameters

I have even enabled the TRACE log on the server in order to check that the module "org.slf4j" (and its dependences) has been correctly loaded.

Do you have any suggestions? I have searched on the web but none seems to have this problem.

Thanks in advance,

Vincenzo

Welcome to the forums!

What does the EJB method that you are invoking look like and what parameter types does it take? Does the object you are passing to the method use any of that above logger? What does that logger declaration look like?

[v.stola]

Hi,

I noted that a parent class of the object passed as parameter had a Logger. I commented the field and now it works.

The declaration of the field is the following:

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

protected Logger logger = LoggerFactory.getLogger(getClass().getCanonicalName());

Do you have any ideas since I use the slf4j for logging?

Thank you,

Vincenzo

First, always put your loggers into a static field.  This will reduce your memory usage (maybe substantially) and improve runtime performance.

Second, if this is not an option for you, consider either making your class implement Externalizable or add a writeReplace() method which returns a serializable class that has a readResolve() method on it.
