<dependsnot> element -------------------- Key: JBMICROCONT-410 URL: https://jira.jboss.org/jira/browse/JBMICROCONT-410 Project: JBoss Microcontainer Issue Type: Feature Request Reporter: Andrew Oliver Priority: Minor Original Estimate: 1 day Remaining Estimate: 1 day Presently you can say: <depends>jboss:service=foo</depends> but you cannot say <dependsnot>jboss:service=foo</dependsnot> The former says only do this once that service starts. The latter says "do not do this if that service starts during deployment and stop the service if it is ever started". Reasons: Mutually exclusive services, error messages. Examples: <mbean name="jboss.mail:service=HARError"> <dependsnot>jboss:service=HARDeployer</dependsnot> </mbean> It would deploy if HAR deployer was not existent and dump an error out to the console: public void start() { System.err.println("************** ATTENTION *****************"); System.err.println("*** HARDeployer not installed.. Rerun the installer and select JBoss 4.0.3+ support. ***"); System.err.println("************** /ATTENTION ****************"); } This would also be useful for the new microcontainer stuff @dependsnot ....
