Jetty8 and JSP

[Chris Boot <debian@bootc.net>]

Hi,

I've been trying to get JSP working on a Jetty8 installation on Wheezy,
with no luck so far. Is this even possible?

So far I've installed default-jre-headless, jetty8 and
libjetty8-extra-java, then edited /etc/default/jetty8 to set
JETTY_ARGS="OPTIONS=default,jsp". This leads me to a number of
exceptions that stop Jetty from starting up:

2013-06-07 17:31:50.440:WARN:oejd.WebAppDeployer:WebAppDeployer is
deprecated. Use WebAppProvider

And so on. Adding some symlinks to /usr/share/jetty8/lib/ext gets me a
little further:

test1 ~ # ls -l /usr/share/jetty8/lib/ext
total 0
lrwxrwxrwx 1 root root 34 Jun  7 17:34 org.apache.el.jar ->
../../../java/tomcat-jasper-el.jar
lrwxrwxrwx 1 root root 29 Jun  7 17:34 org.apache.juli.jar ->
../../../java/tomcat-juli.jar
lrwxrwxrwx 1 root root 28 Jun  7 17:35 org.apache.tomcat.api.jar ->
../../../java/tomcat-api.jar

I can now access Jetty to access plain .html pages, but loading a .jsp
page (just a copy of index.html for now) leads to:

java.lang.IllegalStateException: No org.apache.tomcat.InstanceManager
set in ServletContext
	at
org.apache.jasper.runtime.InstanceManagerFactory.getInstanceManager(InstanceManagerFactory.java:35)
	at
org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:171)
[...]

What am I doing wrong?

Thanks,
Chris
