Is the hot redeploying of permission drools possible now?

[gena]

Hello,

is it possible to redeploy the security.drl file without server restart? It doesn't work automatically at least with the current snapshot. I don't want to configure any other agents or working memories as it would be enough for me, simply to compile / apply the new rules on the fly. In general, i think as many components as possible should be redeployable without the restart and not only during the development.

Is it really a good idea to use drools for simple but, sometimes, context dependant permissions or not?

Thank you for any help,

Gena

Could anybody comment on that ? Is hot deployment of drools possible ?

After experimenting a bit i can tell that it is very simple to hot deploy *.drl files.
All you need to do is copy new rule files to deployment directory (i.e. explode target in seam-gen project) and remove several items :

Contexts.getSessionContext().remove("org.jboss.seam.security.ruleBasedPermissionResolver");
Contexts.getSessionContext().remove("org.jboss.seam.security.defaultResolverChain");
Contexts.getApplicationContext().remove("securityRules");

Note that component name in last line may vary according to your components.xml, mine was :

<drools:rule-base name="securityRules">
      <drools:rule-files><value>/security.drl</value></drools:rule-files>
   </drools:rule-base>

It would be cool if such functionality was included in hot deploy filter.
I think modification of org.jboss.seam.init.Initialization.redeploy method would be enough.

And one more think : how can I find out from java code what name was configured for drools:rule-base ?
