The folder structure is :
EDIT:
Action code:
public class LoginAction extends ActionSupport {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
String target = null;
LoginForm loginForm = (LoginForm)form;
if(loginForm.getUserName().equals("admin")
&& loginForm.getPassword().equals("admin123")) {
target = "success";
request.setAttribute("message", loginForm.getPassword());
}
else {
target = "failure";
}
return mapping.findForward(target);
}
}
You are missing namespace="/"
in package tag of struts.xml
file
<package name="default" extends="struts-default" namespace="/">
<action name="loginForm" class="org.nitish.action.LoginAction">
<result name="success">Welcome.jsp</result>
<result name="failure">index.jsp</result>
</action>
</package>
According to the struts dtd the order of the elements in the configuration file matters. Try
<struts>
<constant name="struts.devMode" value="true" />
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false" />
<bean name="loginForm" class="org.nitish.form.LoginForm"></bean>
<package name="default" extends="struts-default">
<action name="loginForm" class="org.nitish.action.LoginAction">
<result name="success">Welcome.jsp</result>
<result name="failure">index.jsp</result>
</action>
</package>
</struts>
the option to select full namespace taken back to default, there's no reason to change this constant.
and remove
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
the struts is unable to find an action because welcome files served first by the web server.
Now, edit the struts.xml
and add the following in your package
<action name="">
<result type="redirectAction">loginForm</result>
</action>
So, when you go to the web app root path it will execute default action and redirect to the action loginForm
