how can i use request parameter in struts2 if tag
http-request-parameters, java, jsp, ognl, struts2
Solution
Try with
<s:if test="%{#parameters.login[0]=='failed'}">
The two problems were in your code:
- The `=` sign is an assignment, not equals `==`;
Parameters are saved in the `Map<String, String[]>`, so each parameter could have multiple values and accessed by the specifying an index.
The last option also described here: why doesn't the `if` tag evaluate params properly.
Problem
i have a link like this :`http://localhost:8080/ESA/login.jsp?login=failed` in end of above link a set a parameter with name `login` and value `failed`. how i can use this parameter in jsp page with struts if tag. I use following code but it don't work. ``` <s:if test="%{#parameters.login='failed'}"> <div class="error"> <s:text name="user.login.failed"></s:text> </div> </s:if> ```
