Maven QuickStart in Eclipse on Tomcat
I'm trying to run the Wicket QuickStart app in Eclipse on Tomcat. I'm
entirely new to Maven and its dependencies (which seem to be just project
libraries?) I think I have it mostly configured correctly, but when I start
Tomcat I get the following error:
java.lang.ClassCastException: org.apache.wicket.protocol.http.WicketFilter
cannot be cast to javax.servlet.Filter
at
org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:255)
at
org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:397)
.
.
.
Obviously, it's not finding the wicket-1.3.4.jar. Here are my screenshots
from Eclipse:
http://www.nabble.com/file/p19183955/packageExplorer.png
and
http://www.nabble.com/file/p19183955/buildPath.png
So it appears that the wicket jar is there under Maven Dependencies. Is
there anything I need to do in order to get the items under Maven
Dependencies to be recognized by the application?
Thanks much.

If I knew enough about Jetty to be confident that there would be no hitches
there, that would certainly be the optimal solution (and, given your
experience with it, I'm sure you're right.)
But considering that my knowledge of Jetty is perhaps on par with my
knowledge of the history of Abkhazia, I figure that it's safer for now to
run everything in the same server environment.

Yeah, couldn't you just take the war file created by maven and drop it
in your webapps directory of tomcat in your "production" environment?
Use jetty to develop, but tomcat to deploy. That's what we do.

Developing with jetty is very nice, we use it for many projects. For
deployment, to remove any jars during deployment set the scope in the
dependency to provided, see:
http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html
Also, to learn more about maven, google for "Better Builds with Maven"
It is a great resource.

I know -- that's the Jetty one, right? I keep telling myself that as I've
been trying to get this working with Tomcat. But in the I think fighting
with Tomcat will be easier than fighting with our administration to switch
the production server to Jetty.

you could just use the included Start class and have it startup much faster..

That did it. Thanks again. As an aside to anyone else who's also figuring
this out, I had to remove both the servlet-api jar and the
org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER from the list in order to
get it to work.

Ugh. Of course, you're right. I had been getting a ClassNotFoundException
before I tried the DevLoader, and I didn't notice that the error had changed
to ClassCastException afterward.
I'm not sure how to remove servlet-api from the Maven dependencies list. The
Properties/Java Build Path/Libraries approach that I use for normal jars
doesn't work -- the "Remove" option is disabled. My very basic understanding
of Maven would point me at the pom.xml, but that doesn't explicitly list
servlet-api as a dependency either. Where is servlet-api defined as a
dependency, and how do I get rid of it?
Thanks for all your help.

You have to remove the servlet-api jar from the classpath when you run
your application in tomcat.

Are you, by any chance, using the DevLoader plugin to run Tomcat ?
If so, you should go in the tomcat properties of your project, edit the
devloader classpath properties, and disable all jetty jars and the
servlet-api jar ...
Hope this helps,
Antoine.
