Hello ! I was trying to run Cocoon 1.8.2 with Tomcat 4.0.b3 following the instructions found on http://xml.apache.org/cocoon/install.html#tomcat but i get errors : java.lang.NullPointerException at org.apache.catalina.loader.Extension.getRequired(Extension.java:336) at org.apache.catalina.loader.StandardClassLoader.addRepositoryInternal(StandardClassLoader.java:1137) at org.apache.catalina.loader.StandardClassLoader.<init>(StandardClassLoader.java:219) at org.apache.catalina.startup.Bootstrap.createSharedLoader(Bootstrap.java:395) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:122) Exception in thread "main" java.lang.IllegalArgumentException: addRepositoryInternal: java.lang.NullPointerException at org.apache.catalina.loader.StandardClassLoader.addRepositoryInternal(StandardClassLoader.java:1145) at org.apache.catalina.loader.StandardClassLoader.<init>(StandardClassLoader.java:219) at org.apache.catalina.startup.Bootstrap.createSharedLoader(Bootstrap.java:395) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:122) and Tomcat doesn't want to start at all. It seems to me that there is a kind of conflict between the existing Tomcat's libraries and Cocoon's libraries. Is there anybody experienced with Tomcat 4.0 and Cocoon 1.8.2? Any help will be greatly appreciated!
