starting jetty8 ClassNotFoundException: HttpServletResponse

Question

Why is my Jetty 8 startup failing with a ClassNotFoundException for HttpServlet response? What step have I missed?

Running on Ubuntu 12.04.03

I installed openjdk 7 with:

sudo apt-get install openjdk-7-jdk

installed jetty 8 with:

sudo apt-get install jetty8

modified the /etc/default/jetty8 file to set NO_START=0 & the JAVA_HOME=... value.

But when I start jetty with "service jetty8 start" it fails, and the /var/log/start.log shows:

Caused by: java.lang.ClassNotFoundException: javax.servlet.http.HttpServletResponse

The full stack trace is:

what do you see when you type `java -version` in your console? — ljgw, Nov 26 '13 at 21:43
$ java -version java version "1.7.0_25" OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2) OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode) — sea-rob, Nov 26 '13 at 21:44
Hmm, well that seems ok. However; take a look at this answer: http://stackoverflow.com/a/1022941/2430030. — ljgw, Nov 26 '13 at 21:49
That feels like progress. I ran "apt-get install libservlet2.5-java" and it installed something, but same result. I'm surprised the servlet jar isn't bundled in jetty. — sea-rob, Nov 26 '13 at 21:54
Under /usr/share/jetty8/lib, I do see servlet-api-3.0.jar. Why isn't the startup picking that up? — sea-rob, Nov 26 '13 at 21:59
Sorry, that was an unforeseen side effect of the link,... the 2.5 servlet library is probably the incorrect version for you. — ljgw, Nov 26 '13 at 22:13

Try this version instead:

sudo apt-get install libservlet3.0-java

You need to get the implementation that matches your servlet-api version.
