I would like to know whether it's possible to deploy customized Java service class to activiti without restart the application server (wildfly in my case).
Currently, I have to put the jar to classes folder and then restart the whole server. I have already tried HotSwapAgent but it seems not work.
We are addressing this problem in Activiti Cloud: https://activiti.gitbooks.io/activiti-7-developers-guide/content/ But as Philippe mention, if your class is code that changes quite often, you should think about having a separate service for it.
