java EAR库的类为WAR成员抛出ClassNotFoundException

Question

我打包了一个EAR（myear.EAR）文件，并将其部署在JBoss EAP 6（即JBoss 7:）中。 看起来是这样的：

lib/ 
  my-common.jar (Custom library containing common classes used by both the WAR and BIZ)
  --- (other libraries used by both WAR and BIZ) ---
META-INF/
    jboss-deployment-structure.xml (specifies just <ear-subdeployments-isolated>false</ear-subdeployments-isolated> )
my-biz.jar (EJB Module)
    META-INF/
        beans.xml
        MANIFEST.MF
    -- java classes -- 
my-war.war (WAR Module)
    WEB-INF/
        beans.xml
        lib/ (empty! I made a skinny war)
    META-INF/
        MANIFEST.MF
    resources/
    -- java classes --

在my-war.war中，有一个类从my-common.jar中的类调用方法。以下是发生的情况：

public class MyWarMember implements Serializable{//my-war.war

  public void foo(){
    MyCommonMember.deepCopy(this);
  }
}
---------------------------------------------------------------------
public class MyCommonMember{//my-common.jar
  public static Object deepCopy(Serializable obj){

    ObjectOutputStream oos .....
    ...
    oos.writeObject(obj);
    ....
    ObjectInputStream ois ....;
    ....
    ois.readObject(); 
  }
}

对ois.readObject();的调用将为MyWarmMember抛出ClassNotFoundException：

java.lang.ClassNotFoundException: my.war.MyWarMember from [Module "deployment.myear.ear:main" from Service Module Loader]

你将如何解决这个问题？谢谢
