Error using RuleBasedIdentity in Seam 2.0 beta 1

[tuxzilla]

After migrating my app from seam 1.2.1GA to 2.0 beta 1, I am having problem accessing my login page. The exception is

Caused by: java.lang.IllegalArgumentException: Could not invoke method by reflection: RuleBasedIdentity.setSecurityRules(org.drools.RuleBase) with parameters: (org.jboss.seam.drools.RuleBase) on: org.jboss.seam.security.RuleBasedIdentity

I double checked components.xml, it seemed consistent with the drools example:

The view is a standard login form:

 <h:outputLabel for="rememberMe">Remember me</h:outputLabel>

 </h:panelGrid>
 </div>

 </fieldset>

 <div class="actionButtons">
 <h:commandButton value="Login" action="#{identity.login}"/>
 </div>

 </h:form>

Very strange. Its like it cant see the @UNwrap annotation. Are you sure there aren't two seam jars in the cp?

[tuxzilla]

I am pretty sure I only have seam 2.0 jar in the classpath.

Hi,

I had a similar error (though I was in 1.2.1), I was experimenting with replacing the antlr libraries with latest releases and it gave a similar stacktrace as yours. It might have nothing to do with your error, but I thought lets write it down anyway. Moving back to the antlr libraries that ship with 1.2.1 made it work again. Maybe you need another version than you have now in your application.

I have the same error.
Project generated by seam 2.0.0.BETA1 from entities in mysql.
On jboss-4.2.0.GA just downloaded.
java: jdk1.6.0_01.

It happens when I put any rule to my security.drl file and I access any page of my application.

versions of jars:
antlr-2.7.6
antlr-3.0b7
drools-compiler-4.0.0.MR2
drools-core-4.0.0.MR2
janino-2.5.6
mvel14-1.2beta16

On the top it is:

Could you please raise an issue in JIRA, with a deployable test case that reproduces this? There's not enough information here for me to work out what the issue is.

[przemyslawo]

I'm going to do it today.

the seam.drools package was updated yesterday and the drools libs were also updated. You can have a cvs update and ant dist your new Seam. Try it. I had the same problem last week but then manually hacked the old seam.drools package and updated the drools libs myself, the problems were gone.


Regards,
Ellen

Unfortunatelly the problems haven't gone for me.
I've raised this issue in JIRA.
