Try with

<s:if test="%{#parameters.login[0]=='failed'}">

The two problems were in your code:

  1. The = sign is an assignment, not equals ==;

  2. 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.
