Re: [aspectwerkz-user] Hot Deployment for JRockit

Hi
JRockit JMAPI does have hotswap support in version 1.4.x.
See ClassLibrary here:
http://e-docs.bea.com/jrockit/docs142/jmapi/javadoc/Management%20API/index.html
That is:
com.bea.jvm.JVMFactory.getJVM().getClassLibrary().redefineClass(
                          java.lang.Class cl,
                          byte[] buffer,
                          int offset,
                          int length)

As Jonas said we haven't implemented that one under 1.4.* but using
the factory Jonas describes it can be easily done.
Else, using JRockit 1.5, you can of course use -javaagent as it is
part of Java 5 standard, and that one works out of the box on both
JRockit and Sun VM.
