Re: [jetty-users] Jetty 9.4.15 and JSP issue

[Jan Bartel <janb@xxxxxxxxxxx>]

Number 12) apache-jsp should say "transitive provider of apache-jsp for jsp", so there is something wrong with the way the apache-jsp module is being initialized.

There is also a further problem, in that your log output from the dump command throws a NullPointerException - not sure why that is happening or if it is related, but it certainly prevents the dump from showing us your system classpath. Will look into the NPE further. 

Meanwhile, I suggest you do a "java -jar ../start.jar --dry-run" and that output should show us the jars that are on jetty's container classpath. But first, do please check how you have enbled the apache-jsp module - you shouldn't specify it anywyhere, jetty should do it for you if you just enable the jsp module.

Hello,

I am upgrading the jetty in my web application from 9.3 to 9.4.15. I have added support for JSP in the app web.xml and the"jsp" module is included in startup option using "--module=jsp...". Iam using open JDK 11.02. However when I start the application I get 

"java.lang.ClassNotFoundException: org.eclipse.jetty.jsp.JettyJspServlet"

I can see the Apache JSP jars on the container classpath. However I still get the above error.

Any suggestions on how to fix it.
