eclispe WTP kann Webapp unter JBoss nicht starten wg. "Unable to find a javac compiler;"

[f.mayer]

Hallo!

Ich möchte eine J2EE-Applikation aus eclipse WTP 1.5.1
(eclipse-Plattform 3.2.1) unter JBoss 4.0.2 starten. Der JBoss startet
ohne Probleme. Wenn ich dann allerdings eine JSP aufrufen möchte,
wirft der JBoss die folgende Meldung (siehe unten für ausführlicheren
Output):
Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK

Wenn ich jedoch den JBoss manuell als batch starte funktioniert die
Webseite einwandfrei.

Was ich schon geprüft habe:
- Das tools.jar unter Preferences > Ant > Runtime > Gloabl Entries ist
vorhanden.
- Unter Preferences > Java > Build Path > Classpath habe ich ein
JAVA_HOME und die Variable CLASSPATH angelegt (selbe, wie unter
Windows-Einstellungen).
- Unter Preferences > Java > Installed JREs ist die korrekte JDK
gelistet (jdk1.5.0_05)

An was liegt es, dass der JBoss aus eclipse die JSPs nicht umsetzen
kann? Wie behebe ich dieses Problem?

Vielen Dank bereits im Voraus.
Gruß Franz
