Thanks for the quick replies.

I'll look into the TransformerFactory, but if that lookup is primarily
related to JAX then I'm not sure why the code is trying to load DERBY jars
as well (may be because of system-db dependency).

Regarding other questions raised, I'm using clean install of Geronimo
v2.1.3, I'm using my own Java Service Wrapper wrapper.conf with following
jars in it.

------------
wrapper.java.classpath.1=%GERONIMO_HOME%/lib/wrapper.jar
wrapper.java.classpath.2=%GERONIMO_HOME%/bin/server.jar
wrapper.java.classpath.3=%GERONIMO_HOME%/bin/shutdown.jar
wrapper.java.classpath.4=%GERONIMO_HOME%/lib/geronimo-cli-2.1.3.jar
wrapper.java.classpath.5=%GERONIMO_HOME%/lib/geronimo-kernel-2.1.3.jar
wrapper.java.classpath.6=%GERONIMO_HOME%/lib/geronimo-transformer-2.1.3.jar
wrapper.java.classpath.7=%GERONIMO_HOME%/lib/commons-cli-1.0.jar
wrapper.java.classpath.8=%GERONIMO_HOME%/lib/commons-logging-1.0.4.jar
wrapper.java.classpath.9=%GERONIMO_HOME%/lib/cglib-nodep-2.1_3.jar
wrapper.java.classpath.10=%GERONIMO_HOME%/lib/log4j-1.2.14.jar
wrapper.java.classpath.11=%GERONIMO_HOME%/lib/xpp3-1.1.3.4.O.jar
wrapper.java.classpath.12=%GERONIMO_HOME%/lib/xstream-1.2.2.jar
wrapper.java.classpath.13=%JAVA_HOME%/lib/tools.jar
------------

My app is a typical web-service that doesn't have "direct" dependencies on
most of the jars, it has following dependencies (from the Dependency Viewer)

org.apache.geronimo.configs/axis/2.1.3/car
org.apache.geronimo.configs/axis2-ejb/2.1.3/car
org.apache.geronimo.configs/axis2/2.1.3/car
org.apache.geronimo.configs/j2ee-corba-yoko/2.1.3/car
org.apache.geronimo.configs/j2ee-server/2.1.3/car
org.apache.geronimo.configs/openejb/2.1.3/car
org.apache.geronimo.configs/openjpa/2.1.3/car
org.apache.geronimo.configs/system-database/2.1.3/car
org.apache.geronimo.configs/tomcat6/2.1.3/car

If I come up with anything related to TransformerFactory then I'll post the
results to thread.
