I have a jar that has an implementation class which implements an interface which resides in war. Also jar requires certain custom exceptions and some domain classes from war file. I can't put the jar into the war, as it can be altered frequently.
I am deploying this war into wildfly 10. I read one post from stackoverflow and tried it How can i add a jboss 7.1 module that contain classes that implements/extends from classes in the main ear file of the server?, but again I am getting ClassNotFoundException. I put my jar in the standalone folder and give the path for resource in jboss-deployment-structure.xml as 

<jboss-deployment-structure>
    <resources>
        <resource-root path:"../test.jar"/>
    </resources>
</jboss-deployment-structure>

Also I tried doing by referring to it as a module but in turn it needed the dependency from war file which is in different classloader. Can anyone help me with this issue.

Since you say you deploy the JAR you should be using a module dependency not a resource dependency.

<jboss-deployment-structure>
    <dependencies>
        <module name="deployment.test.jar"/>
    </dependencies>
</jboss-deployment-structure>

A <resource/> is used for file system paths. Have a look at the have a look at the documentation for the jboss-deployment-structure.xml.

  • I think there may be a slight confusion. I am deploying the WAR file and I want that external jar to be loaded in the same class loader. I already tried adding this JAR as a module in JBOSS and declaring its dependency in jboss-deployment-structure.xml . But the classloader which loads the modules external to WAR is on higher level of the classloader which loads the WAR. So while I try to deploy it said that unable to link that particular external module to WAR, due to dependency of JAR classes on some WAR classes. – Avijit Saxena Jul 14 '18 at 12:36
  • If you want the JAR loaded in the same class loader as the WAR it needs to be included in the WAR. That's the only way that would work. – James R. Perkins Jul 16 '18 at 15:54
