When you build a route a new
.kar file is generated and it needs to be redeployed on Talend ESB container. Nothing special to do, just copy it on
Talend ESB conatiner is based on Karaf and on starts it “activate” all routes found inside the container/deploy folder.
When you rework a route from the Talend Studio for ESB, you then build it getting a new
.kar file. To deploy that file and replace the old version you need just to overwrite the old copy.
The container finds out it self the new version and deploy it automatically.
That works on version 7.2.1 but it is supposed to work even on other Talend ESB version. I’ve only experimented some problems with version 7.1.1 of Talend but insted to try to understand the reasons I’ve updated it.
You could even think to stick to version 6 which is probably more stable see the list of new features in Talend ESB 7 (yes, I agree, the talend help center is not easy to use…).
