Hot Swap not working on several servers
Hi,
it downloaded a trial of IntelliJ 12 and test it with an Tapestry Project (build from an Maven Archtype). I will use the hot swap feature and tried severel Server. I configured the servers (default configuration with enabling hot swap) and started the debug mode
I have tried: Tomcat 7, TomEE and Jetty 8 (I did not get Jetty 9 working with IntelliJ !)
For all serves i got the followin message after changing something:
Hot Swap failed
TomEE: hierarchy change not implemented;
TomEE: Operation not supported by VM
I try to use hot swap the first time, so i am not familar with it. So maybe i did something wrong!? Or is there a general problem?
Thank you
Sascha

The default hot swap capabilities of the JVM are very restricted. You can change method code, introduce new methods but you cannot change the class signature (add or remove fields, change inheritance).
If you need such things you have to look for a more sophisticated tool. If I remember right there is one called JRebel but you have to pay a yearly fee for it.
I for myself would invest in such a tool if they want a one time fee but not a yearly subscription.
Hi,
thanks for the information. I recognized, that tapestry is working with live reload classes. So i spend some some time to get it work and if you know how, it is very easy ;). So i don't need the hot swap feature...
