What is the reason for this warning?
WARNING: Form token PR78LAIFZJQRTL66GGAJDT61511L6YHN does not match the session token null
JSP:
<s:form method="post" action="test">
<s:token></s:token>
Email:<input name="email" />
</s:form>
Struts.xml:
<action name="test" class="test.RegisterAction">
<interceptor-ref name="defaultStack" />
<interceptor-ref name="token" />
<result name="invalid.token">/error.jsp</result>
<result>/user/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
The order of the interceptor token
should be first. For example
<interceptor-ref name="token" />
<interceptor-ref name="defaultStack" />
The reason why your session token is null
might be the session is expired or closed.
