I saw the compatibility matrix at: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossVsJavaJDKVersionMatrix Under 3.2.x it says compiles with JDK version 1.3/1.4 Does this just mean that the code of the Jboss Server itself needs JDK 1.3 or 1.4 to compile from source? Or does it mean that my application file which I deploy under 3.2.7 needs to compile with the earlier 1.4 JDK? My goal is to move to JDK 1.5 to run and compile my application code just wanted to check which way I should interpret that table. I am assuming that compiling under the new JDK for my application code should be fine as long as I am running under that JDK and I don't intend on compiling jboss src itself as prebuild binaries are fine.
