Tomcat 7 in Java 6 on V5R4 (. . . 3 . . . 2 . . . 1 . . . crash-on-takeoff)

We're now trying to bring up Tomcat 7 on a V5R4 box. They have Java 6 installed, and I'm told that they installed some PTFs over the weekend, but it's still crashing on takeoff.

In catalina.sh, we have:

# Java 6 settings if needed export -s JAVA_HOME=/QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit/jre export -s CATALINA_HOME=/wintouch/tomcat export -s JAVA_OPTS="-Dos400.awt.native=true -Djava.awt.headless=true -Djava.version=1.6 -Xms256m -Xmx512m" # OS specific support. $var _must_ be set to either true or false. cygwin=false darwin=false os400=true case "`uname`" in CYGWIN*) cygwin=true;; Darwin*) darwin=true;; OS400*) os400=true;; esac

and there is definitely a "java" in the /QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit/jre/bin directory, and so far as I'm aware, all the JARs are present in the right subdirectories of /wintouch/tomcat, but in catalina.out, I get:

Attaching Java program to /QIBM/ProdData/Java400/jdk6/lib/charsets.jar. Attaching Java program to /QIBM/ProdData/Java400/jdk6/lib/resources.jar. Attaching Java program to /QIBM/ProdData/Java400/jdk6/lib/rt.jar. eval: 001-0014 Command /QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit/jre/bin/java not found.
java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina at java.net.URLClassLoader.findClass(URLClassLoader.java:432) at java.lang.ClassLoader.loadClass(ClassLoader.java:642) at java.lang.ClassLoader.loadClass(ClassLoader.java:608) at org.apache.catalina.startup.Bootstrap.init(Bootstrap.java:236) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:425)

When I delete catalina.out and try again, I get the same, only starting from the ClassNotFoundException.
