jarkarta-tomcat-5.0.19 an sablevm on alpha arch

Hi
I am running with sablevm-1.11.1on a debian unstable alpha arch box, 
kernel-2.6.10
jakarta-tomcat-5.0.19, (mysql application with java-connector), i get 
the following request for some .jsp files:
Type Exception report
org.apache.jasper.JasperException: Unable to compile class for JS

No Java compiler was found to compile the generated source for the JSP. 

This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar 
from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat 
restart.
If using an alternate Java compiler, please check its installation and 
access path.
