Hi,
i am trying to use myeclipse with tomcat but when i change one of my class (JSF backing beans) i get Hot code replace failed – Scheme change not implemented error, so i need to restart tomcat each time….
what could i do to enable hot code replacement?
regards…
murathazer,
Hot code replacement is limited in its current implementation in the Sun Java VM’s in that you’re not allowed to change the “shape” of a class. So, you can change code inside existing methods, but you can’t add/remove methods, instance or class variables, or change method signatures. Those are called “scheme changes” and Sun simply doesn’t support them in the JDKs.
There is actually a RFE (request for enhancement) on the java bug parade for this issue:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4910812
feel free to vote for it 🙂 Maybe SUN will consider this when more people vote for this RFE. I think it would be a great step forward in terms of productiviy.
