Passing parameters in url while redirecting in Struts2 [duplicate]

Answer 1

I think that should be something like:

<action name="AddPayAction" class="controller.AddPayAction">
    <result name="error">/Error.jsp</result>
    <result name="success" type="redirect">
        <param name="location">Pay.jsp</param>
        <param name="paraA"></param>
        <param name="paraB"></param>
        <param name="msg">SomeMessage</param>
    </result>
</action>

See example at http://struts.apache.org/2.1.6/docs/redirect-result.html

Answer 2

So far the solution that worked for me was

 <result name="success" type="redirect">
                <param name="location">/Pay.jsp?msg=${msg}</param>
 </result>

where the setters and getters of msg are defined in the action

Answer 3

<action name="AddPayAction" class="controller.AddPayAction">
      <result name="success" type="redirectAction">
        <param name="actionName">Pay</param>
        <param name="msg">SomeMessage</param>
      </result>
  </action>

  <action name="Pay">
      <result name="success">/Pay.jsp</result>
  </action>      

If you want to pass a variables value e.g. msg whose getter/setter is declared in AddPayAction then use this

<param name="msg">${msg}</param>

Taking a look to your code, it looks like you just want to end the action in a JSP, so I do not understand why you are trying to do it using redireciton type. I recommend to use default redirect type: dispatcher

<action name="AddPayAction" class="controller.AddPayAction">
    <result name="error">/Error.jsp</result>
    <result name="success">/Pay.jsp</result>
</action>

Notice that as dispatcher is de default type you don't need to write type="dispatcher" in the results. So, now, if you want to have variables available in the JSP, you just need to declare those variables in the action with its get/set methods. For example:

private String msg;

public String AddPayAction() {

    // your action code

    this.setMsg("my message");

    return SUCCESS;

}

public String getMsg() {

    return msg;
}

public void setMsg(String msg) {

    this.msg= msg;
}

Take a look to the result types available.
