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
Russell

Subject: Class not found exception
I'm doing the Tapestry Tutorial. I'm getting the following for the Forms
part of the tutorial:
caught an exception while obtaining a class file for
org.apache.tapestry5.corelib.components.Form
exception
org.apache.tapestry5.internal.services.TransformationException: Error
obtaining injected value for field
org.apache.tapestry5.corelib.components.Form.logger:
java.lang.ClassNotFoundException: org.slf4j.Logger
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:
<Set name="parentLoaderPriority">true</Set>
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!
