As told by docu I added "jira.jelly.on=true" to ~jira/jira-config.properties (Linux) and restarted jira. The log ~jira/log/atlassian-jira.log tells me that jelly should be on:
jira.jelly.on : true
But later:
2012-02-14 10:26:33,139 QuartzWorker-1 ERROR ServiceRunner jelly-0 [atlassian.jira.service.ServiceRunner] An error occured while trying to run service 'jelly-0'. Can not run script because jelly is not turned on.
What did run wrong?
There is a class file "./atlassian-jira/WEB-INF/classes/com/atlassian/jira/jelly/JiraJelly.class" which contains strings like "JELLY_NOT_ON_MESSAGE", "2Can not run script because jelly is not turned on.". Is that ok?
Thanks in advance,
Andi
