Re: [jetty-users] Jetty 9.2.1 and JSP

[Jan Bartel <janb@xxxxxxxxxxx>]

Andrea,

You need to upgrade to jetty-9.2.3 if you want to use a jre but do
runtime jsp compilation OR as a workaround, enable the jstl module.

The reason is this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=443262

It seems that another side effect of the jasper engine not being
initialized correctly when no tlds are found in any META-INF/ location
is that the compiler is not initialized correctly either.

cheers
Jan
