Re: [jetty-users] Jsp configuration class
I was hoping for some feedback  on the error. 

        Configuration.ClassList classlist = Configuration.ClassList
            .setServerDefault(server);

Multiple markers at this line
- ClassList cannot be resolved or is not a field
- Configuration.ClassList cannot be resolved to a
type

I think was due to  an incompatible server object.


Whether my guess was correct or not  ?

Hi Thanks,

I did try this Configuration.ClassList approach earlier  but I was getting an error "

I think was due to  an incompatible server object.

I am working in another project now
this time I inserted the code ,  no eclipse IDE errors reported I guess the server object is compatible.
My code looks like this but still I am missing JSP feature. Not sure the syntax for that.
console error message"  No JSP support.  Check that JSP jars are in lib/jsp and that the JSP option has been specified to start."

I have these two dependencies in pom.xml

<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>apache-jsp</artifactId>
<version>${jetty.version}</version>
</dependency>
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

This is what my code looks like but I don't think I have the jsp configuration in either  variations

       context.setBaseResource(Resource.newResource(webResourceBase));
        context.setConfigurations(new Configuration[]
        {
            new AnnotationConfiguration(),
            new WebInfConfiguration(),
            new WebXmlConfiguration(),
            new MetaInfConfiguration(),
            new FragmentConfiguration(),
            new EnvConfiguration(),
            new PlusConfiguration(),
            new JettyWebXmlConfiguration()
        });

        // === setup jetty plus ==
        Configuration.ClassList classlist = Configuration.ClassList
            .setServerDefault(server);
        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");

        context.setContextPath("/");

The order of that Configuration list is very important.

It would be better to utilize the Server level component and just add the missing pieces you need.

See: 

        // === setup jetty plus ==
        Configuration.ClassList classlist = Configuration.ClassList.setServerDefault(server);

        // Add JNDI support
        classlist.addAfter(
            "org.eclipse.jetty.webapp.FragmentConfiguration",
            "org.eclipse.jetty.plus.webapp.EnvConfiguration",
            "org.eclipse.jetty.plus.webapp.PlusConfiguration");

        // Add Annotation Scanning Support
        classlist.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration",
            "org.eclipse.jetty.annotations.AnnotationConfiguration");

Leave the existing Configurations in place, don't overwrite/replace the entire list like you are doing.
There is no need to configure the WebAppContext directly.

Hi, 

There appears to be a number of ways to configure annotations, jsp support programmatically in the jetty embedded. i.e. Configuration.ClassList. 

I have gone for this implementation. 
Is there a one liner  new class I can insert in this code  to add for JSP  functionality followed by corresponding libraries in the pom.xml ?

context.setConfigurations(new Configuration[]
        {
            new AnnotationConfiguration(),
            new WebInfConfiguration(),
            new WebXmlConfiguration(),
            new MetaInfConfiguration(),
            new FragmentConfiguration(),
            new EnvConfiguration(),
            new PlusConfiguration(),
            new JettyWebXmlConfiguration()
        });
