[jboss-jira] [JBoss JIRA] Created: (JBRULES-867) Can't load classes from expanded class dir on windows
Can't load classes from expanded class dir on windows
-----------------------------------------------------
Key: JBRULES-867
URL: http://jira.jboss.com/jira/browse/JBRULES-867
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Drl Parser/Builder
Affects Versions: 3.0.6
Environment: Windows XP SP2 (problem not reproducable on Linux), JDK
1.5.0_11-b03, Ant 1.7.0, Eclipse 3.2.2
Reporter: Dan Lipofsky
Assigned To: Mark Proctor
Priority: Minor
When running some JUnit tests of our rules from an Ant task or from
Eclipse, we got the following rule compile errors:
org.drools.rule.InvalidRulePackage: Rule Compilation error
The import com.bricsnet.core.util.constants cannot be resolved
UserGroup cannot be resolved
The same rules compile perfectly on the server.
On the server the class is question is only available from a JAR file.
In Eclipse it in an expanded class dir. In the Ant task both the
expanded class dir and the JAR file were in the classpath, but the
expanded class dir was first. Putting the JAR first on the classpath
solved the problem for the ant task (but this is not possible for
eclipse since the JAR is not available). Therefore we believe the
problem is specifically related to loading from an expanded class dir.
The problem seems to occur on Windows but not Linux.
Finally the problem only seems to occur for some classes.
All 3 of the classes in the sample rule file below are
in the same boat, but for some reason only UserGroup
is a problem (it might be the
Example 1 (fails):
package com.foobar.rules;
import com.foobar.core.util.constants.UserGroup;
import com.foobar.core.util.security.principal.UserPrincipal;
import com.foobar.core.util.security.auth.RuleAuthorization;
rule "test_rule"
when
r: RuleAuthorization()
u: UserPrincipal()
eval(u.hasGroup(123))
then
r.setLevel(RuleAuthorization.READ);
end
Example 2 (works):
package com.foobar.rules;
import com.foobar.core.util.security.principal.UserPrincipal;
import com.foobar.core.util.security.auth.RuleAuthorization;
rule "test_rule"
when
r: RuleAuthorization()
u: UserPrincipal()
eval(u.hasGroup(123))
then
r.setLevel(RuleAuthorization.READ);
end
