The exception dd_in_ear_load_EXC_ ocurred. Check log for details.

I got this exception at the WebSphere Application Server 6.1 Console when I was trying to deploy an EAR from JBoss 4.2.
I solved this exception swapping the version of the XML Schema for the Servlet deployment descriptor (web.xml).
I trying to use the Schema version 2.5, but in WebSphere Application Server 6.1 this version is not supported.
I swapped the version to version 2.4, but for the version 2.4 work correctly is necessary that the elements of the tag <servlet> stay in the correct order. In version 2.5 whatever the order =)

The wrong order was:

    ActionServlet
    ActionServlet
    Struts Action Servlet
    org.apache.struts.action.ActionServlet
    
        config/WEB-INF/struts-config.xml
    1

The right order is:

    Struts ActionServlet
    ActionServlet
    ActionServlet
    org.apache.struts.action.ActionServlet
    
        config/WEB-INF/struts-config.xml
    1

Above the exception LOG.

org.apache.axis.InternalException: java.lang.Exception: The OperationDesc for "method" was not synchronized to a method of "class"

 To resolve the exception:

Exception - org.apache.axis.InternalException: java.lang.Exception: The OperationDesc for yourMethod was not synchronized to a method of yourClass.

 You must check the file server-config.wsdd and compare if the method signature described is equals to the method signature of your class.

java.io.IOException: java.lang.IllegalArgumentException: object is not an instance of declaring class at org.apache.axis.encoding.ser.BeanSerializer

If you are developing a Web Service with Apache Axis and in the client occurs the error "premature end of file" and in the server occurs the Exception bellow:

To resolve this problem you must verify the file server-config.wsdd.
In the server-config.wsdd you must search for the mapping of all classes which your Web Service uses.
The BeanSerializer uses this mapping to deserialize all classes.
