Solr fails to serve JSPs, admin interface 404s

Question

I'm having trouble with solr. I'm running it on Ubuntu with OpenJDK:

>> java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.2) (6b22-1.10.2-0ubuntu1~11.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

The admin interface should be served by Jetty 7, which is installed in the solr/example folder according to these instructions: http://wiki.apache.org/solr/SolrJetty#Update_Jetty

On starting solr with 'start.jar' I see the following:

>> java -jar
2012-05-21 14:03:01.121:WARN:oejd.ContextDeployer:ContextDeployer is deprecated. Use ContextProvider
2012-05-21 14:03:01.126:WARN:oejd.WebAppDeployer:WebAppDeployer is deprecated. Use WebAppProvider

...at which point the process ends.

If I instead use 'jetty7.jar', solr starts and runs, but on attempting to access the admin interface at localhost:8983/solr/ I see the following:

HTTP ERROR 404

Problem accessing /solr/. Reason:

    Servlet Not Initialized
Caused by:

javax.servlet.UnavailableException: Servlet Not Initialized

The output on the command line is the following:

>> java -jar jetty7.jar

I assume that the "NO JSP Support for /solr, did not find org.apache.jasper.servlet.JspServlet" line is the culprit.

Any ideas why this would happen?

Eventually cracked it: I realized I had not copied start.ini along with start.jar from the jetty folder and there was some needed configuration in there.
