Trinidad API usage caused an exception on weblogic managed server in my case

Question

I faced an exception when I try to deploy to new created managedServer (which applied JRF). When application wants to use org/apache/myfaces/trinidad/model/ChildPropertyTreeModel class, occured exception below. That was used to be run properly on WC_Spaces. Even if I copied the trinidad-api, trinidad-api-impl.jar libraries into domainhome/lib folder, nothing changes.

What might be the reason?

Answer 1

I had a custom class extended ChildPropertyTreeModel and implements Serializable. I ve made it Serialized with SerializedTreeModel. And this class was in another project(structure) in another word war deployment package's web-inf/lib has contained this class. After i replaced the SerializedTreeModel class location into the same package with refered project, eventually solved the problem. I could not understand the magic honestly.

public class SerializedTreeModel extends ChildPropertyTreeModel implements Serializable
{
    public SerializedTreeModel(Object dataList, String dataChild)
    {
        super(dataList, dataChild);
    }
}
