When evaluating Alfresco 3.3, i noticed two (minor) issuse regarding deployment of JAR files:
1) There are two versions of wstx-asl library jar in WEB-INF/lib:
which is perhaps no good...
2) postgresql-8.4-701.jdbc3.jar is deployed to WEB-INF/lib
Not really an error, but IMHO it should live in tomcat/lib like the MySQL connector...
