JBoss EAP 6 cannot find JARs in APP-INF/lib

Question

I am doing a migration from Weblogic to JBoss EAP 6.4 but I am having a problem deploying to and starting the JBoss server.

My EAR structure is as follows:

.EAR
|
|---APP-INF
|      |---lib
|           |---[many .jar files]
|
|---META-INF
|       |---application.xml
|       |---jboss-deployment-structure.xml
|
|---[EJB JAR files]

The problem:

The EJB JARs in the root of the EAR cannot access the classes in the JARs that are in the APP-INF/lib folder.

Check the [JBoss Windup migration tool](https://github.com/windup/windup/wiki). — Ondra Žižka, Apr 05 '16 at 11:06

I manually put the lib folder at the root of the EAR instead of in the APP-INF folder and it seemed to do the trick.

JBoss was looking inside .EAR/lib instead of .EAR/APP-INF/lib

Then, I added the following in the maven-ear-plugin section in my pom.xml to get maven to create the lib folder at the root and not in APP-INF:

<plugin>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.9.1</version>
    <configuration>
        <defaultLibBundleDir>lib</defaultLibBundleDir>
        <goals>
            <goal>generate-application-xml</goal>
            <initializeInOrder>true</initializeInOrder>
        </goals>
    </configuration>
</plugin>

Do you run jboss on windows? I noticed that I can use sub catalogs like `APP-INF/lib` or `my/lib` on mac but it fails on windows. Also tried backslash with no success. – Love Oct 06 '17 at 09:57
@Love yes, I did it on Windows – Tanvir Oct 10 '17 at 19:41

The APP-INF/lib location is specific to WebLogic. There are two solutions:

Make Maven build the app according to standards - /lib. That's what you did in your answer.

Since Java EE 5 you can include the library-directory parameter in your META-INF/application.xml file:

<application xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd">
   <module>
      <ejb>hello-ejb.jar</ejb>
   </module>
   <module>
      <web>
     <web-uri>myapp.war</web-uri>
     <context-root>myapp</context-root>
      </web>
   </module>
   <library-directory>APP-INF/lib</library-directory>
</application>

As an alternative, you can include the same parameter in your jboss-app.xml:

    <application>
      <display-name>My Application</display-name>
      <module>
        <web>
          <web-uri>myapp.war</web-uri>
          <context-root>/myapp</context-root>
        </web>
      </module>

      <module>
        <ejb>myapp.jar</ejb>
      </module>

      <library-directory>APP-INF/lib</library-directory>

    </application>
