Add the following code snippet into the struts.xml file.

struts.xml

<action name=”actionerrorTag”>
<result>/pages/nonformTags/login.jsp</
result>
</action>
<action name=”login”
class=”net.javajazzup.CheckValidUser”>
<result name=”input”>/pages/
nonformTags/login.jsp</result>
<result name=”error”>/pages/
nonformTags/error.jsp</result>
<result>/pages/nonformTags/
validuser.jsp</result>
</action>

Create an action class that uses methods addActionMessage(String) and addActionError(String) within the execute() method. The addActionMessage(String) will print the passed string on the success jsp page while the addActionError(String) will print the passed string on the error jsp page.

CheckValidUser.java

package net.javajazzup;
import
com.opensymphony.xwork2.ActionSupport;
import java.util.*;
public class CheckValidUser extends
ActionSupport {
private String username = null;
private String password = null;
public String execute() throws Exception{
if ((getUsername().equals(“javajazzup”))
&&
(getPassword().equals(“javajazzup”))){
addActionMessage(“Valid User”);
return SUCCESS;
}
else{
addActionError(“Invalid User”);
return ERROR;
}
}
