Jenkins is now using embedded jetty

[Indra Gunawan (ingunawa)]

Ever since version 1.535, java –jar jenkins.war now runs on Jetty8:  (issue 18366)

After we upgrade to LTS version 1.554.3 Now we see this in the Jenkins log every time :

…

Dec 14, 2014 9:12:33 PM winstone.Logger logInternal

INFO: Beginning extraction from war file

Dec 14, 2014 9:12:35 PM org.eclipse.jetty.util.log.JavaUtilLog info

INFO: jetty-8.y.z-SNAPSHOT

Dec 14, 2014 9:12:37 PM org.eclipse.jetty.util.log.JavaUtilLog info

INFO: NO JSP Support for , did not find org.apache.jasper.servlet.JspServlet

I googled this topic and my conclusion is that  either we switch to Jetty and deploy Jenkins in Jetty or we figure out how to  install jetty-jsp package for example on this Fedora 20:

https://major.io/2014/08/13/get-jenkins-start-fedora-20/

Is that correct?

I do not think there is jetty-jsp RPM readily available for CentOS 5/RHEL 5.x where we use to deploy Jenkins.

Thank you.

Hi,

Jenkins does not need JSP support - it uses alternate technology for building its web pages.

So you can safely ignore this message.

How do you monitor/debug Jenkins now since this Monitoring plugin will fail to load without JSP support now.

Thank you.

I guess this plugin requires jsp:

Hello Folks,

I am running into this issue with Jenkins 1.625.3 running on Ubuntu 14.04

Is there a work around to this issue?

Thanks

-Sam

Could you explain the behavior you're seeing which makes that an issue?  What does Jenkins do when that log message appears?

Did you install from the operating system package manager (apt-get or aptitude are my favorites) or in some other way?  If some other way, have you considered switching to use the operating system package manager?
