RE: Class not found exception
I don't think run jetty run supports configuration by a jetty.xml. The
author says in his "Usage" instructions
"There aren't many options, just the web application directory, the
context and the port. I intentionally keep it basic so that it will be
easy to use and maintain; if you need anything more fancy, use one of
the other Eclipse app server plugins, or do what I often do: create a
start up class in your project."
Not sure where that leaves you. Sorry I can't be more help. The basic
problem is the same. You need to tell Jetty that you don't want it to
"hide" the slf4j server classes. One way of doing that is setting the
ServerClasses property as Ben did below. How you set that property with
run-jetty-run is beyond me. Sorry.
If you look at the wiki post linked to in my post you can just cut and
paste the code into a run class and you will be up and running very
quickly indeed. I agree with your "shoulds"...but maybe ditching
run-jetty-run would help.
Cheers
Russell

Thanks Russell.
I had seen that one too but I'm afraid that, while I understand the
underlying problem, the wiki entry solution doesn't mean a great deal to
me as I am have not been using Maven for very long and don't know much
about POMs or artifacts.
I don't see why I should have to have a "run class". Surely it should
just all work out of the box (or at worst, by modifying a Jetty XML file
as I initially tried).
Thanks.

Hi,
I asked about this a few weeks back and Ben Gidley pointed me at the
wiki with these words
" What is happening is Jetty hides 'server' classes from the web
application unless they are also in WEB-INF/lib. When you run in the IDE
you don't have a WEB-INF/lib so it can't find the slf4j classes as they
are loaded by Jetty as server classes.
You are starting Tapestry inside your IDE using a Run class - you need
to add a line into your startup class saying
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{"-org.mortbay.jetty.plus.jaas.", "org.mortbay.jetty."});
see http://wiki.apache.org/tapestry/Tapestry5RunViaMain for more
details.

Hope that helps

I'm doing the Tapestry Tutorial. I'm getting the following for the Forms

I'm using Jetty 6 and Jetty Runner in Eclipse and I'm attempting to do
the Tapestry Tutorial.
I see this has been raised before and is supposedly a "Jetty Error".
Unfortunately I am not knowledgable enough to fix this myself (and
really, the Tutorial should say something about this and give a fix
rather than leaving novices like me hanging with no idea what is going
on. Apologies if there is something about this, but a Google search
turns up very little).
One solution was for jetty.xml to have:

I've done this, but it doesn't fix the problem.
mvn jetty:run
does allow the page to load, but I want to be able to run Jetty from
Eclipse.
Can someone either point me at a solution or provide one? (and please,
it has to be in terms a novice can understand).
Thank you!
