[jboss-user] [Beginner's Corner] - 6.0.0.Final collisions running existing code

Robin Hughes [http://community.jboss.org/people/rhinmass] created the discussion "6.0.0.Final collisions running existing code" To view the discussion, visit: http://community.jboss.org/message/598281#598281 -------------------------------------------------------------- I am developing an ejb application that needs to include use a lot of existing code developed for jboss 4.0.5 .  The existing code leverages hibernate 3.2.7    If I include hibernate-3.2.7.ga.jar in my ear, I get many errors such as: java.lang.ClassCastException: org.hibernate.hql.ast.HqlToken cannot be cast to antlr.Token     at antlr.CharScanner.makeToken(Unknown Source) [:6.0.0.Final]     at org.hibernate.hql.ast.HqlLexer.makeToken(HqlLexer.java:62) [:3.6.0.Final] ... So my more general question is how can I run existing code which uses jars that conflict with container jars? Thanks for any assistance or pointers. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/598281#598281] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
