requires javac, but installs a JRE, not JDK

after installing the JDK package I get:

Problem accessing /solr/. Reason:

Unable to load class for JSP

which at least seems to confirm that installing the JDK was the right move to get one step forward.

and after restarting jetty it seems to be working.

ubuntu@server-11007:~$ sudo service jetty start
 * Could not start Jetty servlet engine because no Java Development Kit
 * (JDK) was found. Please download and install JDK 1.4 or higher and set
 * JAVA_HOME in /etc/default/jetty to the JDK's installation directory.

Lots of small issues here:

1) solr-common currently depends on openjdk-6-jre-headless as its primary runtime.

2) jetty accepts java5-runtime-headless as a dependency (provided by openjdk-6-jre-headless) but does not do a great job of checking for the new multiarch locations for openjdk-6

As a result it can't find the runtime provided by openjdk-6-jre-headless.

As a workaround installing default-jre-headless will fix the jetty startup issue.

3) solr-common ships uncompiled JSP's so jetty really does need default-jdk to operate correctly. I'm not actually sure whether this is an issue with solr or jetty.

Installing default-jdk and restart jetty resolves this issue.

This bug was fixed in the package jetty - 6.1.26-1ubuntu1
