Solr 1.x and 3.x uses JSP for its admin UI, so you must have JSP support
in the servlet container.  With many servlet containers, JSP support
requires the Java JDK, not just the JRE -- the container may need to
compile the JSP code on the fly.  This is the usual solution for people
that get this JasperException.

It is *strongly* recommended that you use the jetty included with Solr,
not a third-party container.  That jetty has been tuned for Solr's needs.

The admin UI in 4.0 and later doesn't use JSP.
