I found why it is failing on our zone. Java 1.4 is in use there and its compile phase reports:
-------- /export/opt/forrest-trunk/main/java/org/apache/forrest/conf/AntPropertiesModule. java:31: cannot access org.apache.cocoon.components.modules.input.AbstractJXPath Module bad class file: /export/opt/forrest-trunk/lib/core/cocoon-2.1.12-dev.jar(org/apa che/cocoon/components/modules/input/AbstractJXPathModule.class) class file has wrong version 49.0, should be 48.0 -------- So it seems that our new Cocoon jars were built with Java 1.5 Thorsten are you able to rebuild them. If no time now then say so and i will do it. -David
