Error description

  • Abstract:
    
    Attempting to publish a utility module with web fragments in a
    non-single-root EAR results in ClassNotFoundException.
    
    Problem:
    
    1. Create a new Dynamic Web project within an EAR
    2. Create a simple JAR with one class and a hello world method
    and a file META-INF/web-fragment.xml containing the following
    content and export it as a JAR file:
    
    ??xml version='1.0' encoding='ISO-8859-1'??
    ?web-fragment xmlns='http://java.sun.com/xml/ns/javaee'
        xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
        xsi:schemaLocation='http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-fragment_3_0.xsd'
        version='3.0' metadata-complete='true'?
        ?name?awebfragment?/name?
        ?distributable/?
    ?/web-fragment?
    3. Open Project Properties, Deployment Assembly, click Add ?
    Archives from File System and point to the .jar file from step
    2.
    4. Create a new servlet referencing the class with the hello
    world method from 2.
    5. Break the single-root rule, e.g. by changing the Java output
    folder from WebContent/WEB-INF/classes to classes
    6. Run the servlet on WebSphere Application Server 8.0 or
    WebSphere Application Server 8.5
    
    Actual Result:
    ClassNotFoundException for the class within .jar file from 2
    since it is not copied to
    .metadata\.plugins\org.eclipse.wst.server.core\tmpX
    
    Expected Result:
    Files are copied correctly by Rational Application Developer
    
    Local fix:
    
    Make your project single-root
