Java EE (Java Enterprise Edition) General Discussion

Hello,

When I try to use the ActionMessage class in a class that is not an Action or Form, I get a ClassNotFoundException.

I have the following function in a common utility class.

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionMessage;

public static void creatNetfError(String errorCode, ActionErrors errors)
{
if (errorCode == null)
errors.add("keyError", new ActionMessage("title.error.msg"));
else
{
errors.add("title", new ActionMessage("title.error.msg", errorCode));
errors.add("description", new ActionMessage("error.msg"+errorCode));
}
}

Then call it in my Action class:

ActionErrors errors = new ActionErrors();
CommonUtil.creatNetfError(request.getParameter("errorCode"), errors);
this.saveErrors(request, errors);

I get the following two exceptions (expanded format is attached at the end):
java.lang.NoClassDefFoundError: org/apache/struts/action/ActionMessage
java.lang.ClassNotFoundException: org.apache.struts.action.ActionMessage

This seems to happen if I call org.apache.struts.util.MessageResources, or org.apache.struts.util.ActionErrors in an outside helper class as well. I haven't seen anything in the documentation discouraging use of this package in other classes. Am I missing something? Usually when I get a ClassNotFoundException it is because I am missing a jar file, but in this case I am able to use the classes directly in the Action so that leads me to believe the jar file is installed correctly. Is it possible it is installed incorrectly?

Can anybody point my search in the right direction please?

Thank you

Alfreda
