JAAS + Primefaces: Login form not redirecting to error page

Question

I believe that you will be able to help me with the below problem.

I'm starting my adventure with Java EE and Primefaces and need a bit of help to understand/fix the problem.

So I've created login module using Jaas and below configuration:

web.xml

<login-config>
    <auth-method>FORM</auth-method>
    <realm-name>authRealm</realm-name>
    <form-login-config>
        <form-login-page>/public/login.xhtml</form-login-page>
        <form-error-page>/public/loginError.xhtml</form-error-page>
    </form-login-config>
</login-config>

login_page_1.xhtml

<p:panel header="Login From">
    <form method="POST" action="j_security_check">
        Username: <input type="text" name="j_username" />
        Password: <input type="password" name="j_password" />
        <br />
        <input type="submit" value="Login" />
        <input type="reset" value="Reset" />
    </form> 
</p:panel>

This configuration work just great however as I'm using primefaces as front-end framework I would like to make my page look better. I found below resolution:

login_page_2.xhtml

<p:panel header="Login From">
    <h:form id="loginForm" onsubmit="document.getElementById('loginForm').action='j_security_check';" prependId="false">
        <p:panelGrid columns="2"> 
            <p:outputLabel for="j_username" value="Email" />
            <p:inputText id="j_username" />

            <p:outputLabel for="j_password" value="Passwort" />
            <p:password id="j_password"/>

            <p:commandButton id="login" value="Login" ajax="false" />
        </p:panelGrid>
    </h:form>
</p:panel>

The problem is that when I use login_page_1.xhtml and put wrong credentials (wrong username/password) I got redirected to errorLogin.xhtml (this is desirable behavior) however when I use login_page_2.xhtml I get below erorr

An Error Occurred:

Index: 0, Size: 0

Warning:   WEB9102: Web Login Failed: com.sun.enterprise.security.auth.login.common.LoginException: Login failed: Security Exception

I would be grateful for any help !

Thanks in advance.

Just remove the attribute onsubmit and prependId. Something like this should work..You need to implement a login method though.

<p:panel header="Login From">
    <h:form id="loginForm" >
        <p:panelGrid columns="2"> 
            <p:outputLabel for="j_username" value="Email" />
            <p:inputText id="j_username" />

            <p:outputLabel for="j_password" value="Passwort" />
            <p:password id="j_password"/>

            <p:commandButton id="login" value="Login" action="#{aMethod}" />
        </p:panelGrid>
    </h:form>
</p:panel>
