I had a working Seam 1.1.6 application to which I added the jars and
configuration to implement Seam Security, per the 1.1.6 reference doc. Just to
see if everything was configured properly, before I configured any application
specific rules, I used the security.drl file from the example in the ref doc:
package MyApplicationPermissions;
import org.jboss.seam.security.PermissionCheck;
import org.jboss.seam.security.Role;
rule CanUserDeleteCustomers
when
c: PermissionCheck(name == "customer", action == "delete")
Role(name == "admin")
then
c.grant()
end;
JBoss AS startup looks fine, but when my browser tries to load the first page
of the app, I get the following error below about "c.grant() not a type". FYI,
I have no permission checks in the page my browser is loading. (and in fact, it
finally loads OK) Can anyone provide insight into the error below and, even
better, provide some example Seam-Drools code that is doing permission checks,
so that maybe I have something better to work with. I am new to drools/JBoss
Rules and, other than the Seam Ref Doc, I cannot find any references to Seam
Security Drools code doing PermissionChecks...
Thanks!
Here's the error:
