One more thing ...
Why are you not checking the form in your FormClass overriding
the validate method...
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
....
}

Subject: validating form and what then?
Hi,
i've got a problem. i've done in my app an form where user must input
login and password then this form is validated and then a want to test
if this values are good or bad (LoginCheck.java), but form is null,
why? How can I get login and password values and test if they are
good?
now my app:
(struts-config.xml)
<action path="/Login" forward="/pages/Login.jsp"/>
<action path="/login-check" type="peceka.LoginCheck">
<forward name="success" path="/pages/LogOK.jsp" />
<forward name="error" path="/Login.do" />
</action>
<action path="/login-submit" type="peceka.LoginAction"
name="loginForm" scope="request" validate="true" input="input">
<forward name="input" path="/Login.do" />
<forward name="success" path="/login-check.do" />
</action>
...
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames"
value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>
</struts-config>
