the error is in loginRequired property which is already defined in my web.xml in the file UserActionMapping
here's the java file:
package com.fltic.crm;

import org.apache.struts.action.ActionMapping;

public class UserActionMapping extends ActionMapping {

protected boolean loginRequired = false;

public UserActionMapping() {

super();
}

public void setLoginRequired(boolean loginRequired) {

this.loginRequired = loginRequired;
}

public boolean isLoginRequired() {

return loginRequired;
}
}
============================
what do i need to let my struts app works because it do works in resin.

please help me.

thanks a lot everyone.

Hello
I have the same error and I can't find information to resolve it. Does somebody have the answer ?

Hi,

I have not had the need to extend ActionMapping till now, so finding this solution took a bit of work and understanding. Here's what I found.

Struts 1.0 allows you to specify an alternate ActionMapping class to be used for holding action mappings. This is done with the "mapping" initialization parameter to the Struts controller servlet (as you have done).
This is however deprecated in Struts 1.1 (I found this in the javadoc comment for the class ActionServlet). Struts 1.1 allows you to define different ActionMapping classes for different modules/actions. This can be configured using the "className" attribute of each <action> element, or globally for a module by using the "type" attribute of the <action-mappings> element.

This would mean changing your struts-config.xml to do one of the following:

<action-mappings type="com.fltic.crm.UserActionMapping">

OR

<action
path="/TmMainTaskList"
type="com.fltic.crm.action.tm.TaskListAction"
scope="request"
className="com.fltic.crm.UserActionMapping">
<set-property property="loginRequired" value="true"/>
<forward name="success" path="/tm-main.jsp"/>
</action>

I hope this solution fixes your problem. Please do let us know.

Thank you Sheldon Fernandes

!!!

You're fantastic.
It's good: my program does a good work now !

bye

Check your class path.
if u not set it then please reset as below.

System classpath is irrelevant.
You run a struts application through a web/application server.
As far as the server is concerned, the classpath is
1 - the directory /WEB-INF/classes
2 - jar files in /WEB-INF/lib/(struts.jar)
3 - server library files. eg with Tomcat jar files in the directories [TOMCAT]/shared/lib and [TOMCAT]/common/lib
