HTTP Error 500 Compiling JSP's [SOLVED]

Basic Problem:  I am unable to compile jsp's and display them via Tomcat.  I am using the Netbeans IDE for web development and webapps that use html files/servlets run just fine.  It's when I try to run a jsp that I get an Error 500:

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: java.lang.IllegalStateException: No Java compiler available

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.25 logs.

My config is as follows:

kernel 3.2.4-1-ARCH
Tomcat: 7.0.25
jdk: 7-3
$ java -showversion
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Server VM (build 21.0-b17, mixed mode)
Netbeans: 7.1

I am running the Sun JRE/JDK.

I emailed the Tomcat mailing list and was told the compiler should be in a file called ecj-3.7.1.jar.  I did a locate on that file and I found the following in /usr/share/java:

lrwxrwxrwx   1 root root      21 Nov  7 20:41 ecj.jar -> eclipse-ecj-3.7.1.jar
-rw-r--r--   1 root root 1183268 Nov  7 20:41 eclipse-ecj-3.7.1.jar
lrwxrwxrwx   1 root root      21 Nov  7 20:41 eclipse-ecj.jar -> eclipse-ecj-3.7.1.jar

According to the fellow who I think is the Tomcat maintainer, the eclipse-ecj-3.7.1.jar isn't distributed in standard Tomcat and so to ask whoever packaged mine, which I installed with pacman.

Thanks.

UPDATE:  I uninstalled tomcat7 via pacman and installed the stock Tomcat7 from apache.org.  Jsp's now compile.
