Hi,
we have an appliation that uses Jetty in an embedded way since "the
begin of the world" (the configuration files have had a DTD-declaration
for Jetty 6... ;-)
I'm in the process of migrating from 9.4 to 10.0 and after going the
simple way by replacing the 9.4-jars with the jars of 10.0 the server
is starting up, programmatically added servlets are executed but
WARs loaded by the DeploymentManager lead to errors. I assume that
this simple approach is the reason. When starting up the following
messages show up:
Starting HTTP-server 'Main Server'

I'm wondering about the claim that JettyJspServlet and ELContextCleaner can't be
found. Both are in the classpath and can be found in the class starting the
server
(checked with Class.forName).
What's the best way to embed Jetty 10? Resources online I've found only
cover Jetty up to version 9. The online documentation (Operation
and Programming don't mention Embedding at all - at least in the TOC).
Thanks and best regards,
Lothar Kimmeringer
