How to create a dynamic URL in Struts 2

Question

I have created form login.jsp and when user enter username & password then i want to create URL like : /companyName/username.

Example : If company name is abc and username is parth1 then URL is

"http://localhost:8080/Temp_Central_Emp/abc/parth1/afterLogin.jsp"

I get companyName from the database based on the username.

File : login.jsp:

<s:form action="afterLogin" method="post">
    <s:textfield label="Enter username" key="userId" maxlength="5" size="30" id="userId"/>
    <s:password label="Enter password" key="userPsw" size="30" />
    <tr>
        <td></td>
        <td>
            <img src="<c:url value='simple-captcha.png' />" />
            <br />
            <p>Press F5 for refresh.</p>
        </td>
    </tr>
    <s:textfield label="Enter code" key="captchaResponse" size="30" />
    <s:submit value="Login" />
</s:form>

File : struts.xml:

<struts>
<constant name="struts.enable.SlashesInActionNames" value="true"/> 
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
<constant name="struts.devMode" value="true" />
<package name="a" extends="struts-default">
 
    <action name="afterLogin" class="com.parth.LoginAction">
        <result name="success">/afterLogin.jsp</result>
    </action>

</package>

File : LoginAction.java:

public class LoginAction extends ActionSupport{

private Map<String, Object> session;
private String userId;
private String userPsw;
private String url;

private static final long serialVersionUID = 1L;

@Override
@Action(value="{url}/afterLogin")
public String execute() throws Exception {      
    // business logic to insert user into database
    url = "/companyName/" + userId;
    return SUCCESS;
}

 /* Getters and Setters */
}

try to put that url variable in your struts.xml:

<action name="afterLogin" class="com.parth.LoginAction">
    <result name="success">${url}/afterLogin.jsp</result>
</action>

and remove your annotation Action here:

@Override
//@Action(value="{url}/afterLogin") // remove this
public String execute() throws Exception {      
    // business logic to insert user into database
    url = "/companyName/" + userId;
    return SUCCESS;
}

thanks. But i receive error : **HTTP Status 404 - /Temp_Central_Emp/companyName/parth/afterLogin.jsp** – Parth Patel Feb 21 '17 at 07:06
I think you need to dynamically change your companyName too. – msagala25 Feb 21 '17 at 08:09
If you have idea then please edit the above code which you wrote. – Parth Patel Feb 21 '17 at 09:10

The result should be of redirect action type if you want to change the URL and follow PRG pattern. See Parameters in configuration results:

<result name="success" type="redirectAction">afterLogin?companyName=${companyName}&userId=${userId}</result>

<action name="afterLogin">
   <result>/afterLogin.jsp</result>
</action>

After using your code url is **http://localhost:8080/Temp_Central_Emp/afterLogin.jsp?/CompanyName/parth** but i want **http://localhost:8080/Temp_Central_Emp/CompanyName/parth**. So where i need to change to get this URL? – Parth Patel Feb 23 '17 at 04:32
You should use different actions one for logon and another after logon. – Roman C Feb 27 '18 at 01:33
