Thanks Jan, looks perfect, although I'm seeing an NPE when I try; I
wasn't sure about the need for isErrorPage="true" in the error page, but
I've tried with and without. With, the generated servlet code NPE's at:
response.setStatus(((Integer)request.getAttribute("javax.servlet.error.s
tatus_code")).intValue());
with the stack trace:
at
com.sun.enterprise.web.connector.grizzly.ssl.SSLWorkerThread.run(SSLWork
erThread.java:106)
Caused by: java.lang.NullPointerException

<login-config>
<auth-method>FORM</auth-method>
<realm-name>custom_realm</realm-name>
<form-login-config>
<form-login-page>/login/login.jsp</form-login-page>
<form-error-page>/login/login_error.jsp</form-error-page>
</form-login-config>
</login-config>
And without the stack trace is altered a little, but still NPE's when
accessing pageContext.getErrorData(). Might be something I'm not
configuring correctly (version is v2 b50g).
