Hi Gregory,
Thanks for your extended help, we were able to resolve JSP issue ( login page
not loadable).
with following code changes.
Before starting the server, added this line of code.
org.eclipse.jetty.webapp.Configuration.ClassList classlist =
org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(this.adminServer);
classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration",
"org.eclipse.jetty.plus.webapp.EnvConfiguration",
"org.eclipse.jetty.plus.webapp.PlusConfiguration");
classlist.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration",
"org.eclipse.jetty.annotations.AnnotationConfiguration");
currently we get distorted ( not properly rendered ) Login JSP page, we are
trying to resolve that issue,
Note: we have already upgraded from Java 6 to 8before starting working on this.
Regards,
Sujay

Subject: Re: [jetty-users] Issue with Jetty 9.4
Your app has a dependency on the old tomcat Instancemanager. You will want to
upgrade your webapp to address the breaking changes between Jetty 6 and Jetty
9.4 (and there are a lot). I’m assuming you are also going from Java 6 or 7 to
Java 8 or higher in the process?

Subject: [jetty-users] Issue with Jetty 9.4
Hello Jetty users,
We are facing issue while upgrading jetty v6 to jetty v9.4.15. We have used
dependency jars shipped with Jetty distribution v9.4.15:
Though server get started successfully, when try to access Login page ( a JSP
page ) it does not get displayed on the screen.
Rather we get “error 503” with java.lang.IllegalStateException.
For all filter's mentioned in web.xml, Init() method gets called but doFilter()
does not get called.
Also find attached file “classpath_Error_reproduced.xml" which has all the
jetty files which we have used in our workspace.
Can anyone help us out to resolve current issue we are facing ?
Here is the call stack & error we get on browser :
HTTP ERROR 503
Problem accessing /ediscovery/login.jsp. Reason:
