Load a JBoss module (e.g. log4j) as a dependency in web apps

[lauradp]

Hello everybody,

I was trying to load log4j (but I'd like to do the same thing with hibernate and other libraries) as a dependency of my web application (app.war).

As first attempt I create a file named jboss-deployment-structure.xml in the WebContent/WEB-INF folder of my Dynamic Web Project:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">

<deployment>

  <dependencies>

  <module name="org.apache.log4j"/>

  </dependencies>

</deployment>

</jboss-deployment-structure>

but I got this error:

11:27:19,036 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/MyApp]] (MSC service thread 1-8) Servlet /MyApp threw load() exception: java.lang.Error: Unresolved compilation problems:

  The import org.apache.log4j cannot be resolved

  Logger cannot be resolved

Then I added log4j to the application server global modules:

<subsystem xmlns="urn:jboss:domain:ee:1.0">

            <global-modules>

                <module name="org.apache.log4j" slot="main"/>

            </global-modules>

        </subsystem>

but the error was the same.

My last attempt was adding it to MANIFEST.MF:

Dependencies: org.apache.log4j

with the same result

Can anyone help Me?

Laura

Laura, for access of module org.apache.log4j there is nothing to do, this dependency is always available.

See Implicit module dependencies for deployments - JBoss AS 7.0 - Project Documentation Editor.

No dependencies, not needed triggers.

That's also my experience for all JBoss AS 7 and WildFly versions.

May be it's best to get step back, omit jboss-deployment-structure.xml and any Dependency entries in manifest files, class-path entries, global modules etc.

If problem persists, show us again what you get, the stacktrace, etc.

Can you paste complete org.test.myApp.applicationLayer.servlet.StartupServlet.java file?

[lauradp]

Here is my class:

package org.test.myApp.applicationLayer.servlet;

import org.apache.log4j.Logger;

public class StartupServlet extends HttpServlet {

  private static final long serialVersionUID = 8912623154134195707L;

  private static Logger trace = Logger.getLogger(StartupServlet.class);

  public void init(ServletConfig config) throws ServletException {

  trace.info("it works");

  }

}

[ctomc]

can you attach your war, so we can try to reproduce it.

either war, or some buildable sources (preferred on github)

of course remove everything that is unrelated to this problem.

[lauradp]

Hi,

I attached my war!

Hello,

You might try org.jboss.logmanager.log4j instead of org.apache.log4j as a dependency.

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">

<deployment>

  <dependencies>

  <module name="org.jboss.logmanager.log4j"/>

  </dependencies>

</deployment>

</jboss-deployment-structure>
