Seam Guice with Seam 2.1.0GA?

[legart]

Hello

I'm trying to get Seam Guice to work in a Seam 2.1.0GA project.

* seam-guice.jar and guice.jar added to classpath
* |xmlns:guice="http://jboss.org/jbosslabs/seam-guice" added to start of compnents.xml|
* added http://anonsvn.jboss.org/repos/labs/labs/jbosslabs/labs-3.0-build/integration/seam-guice/src/main/resources/guice-2.1.xsd to xsi:schemaLocation
* added the following to components.xml


`<guice:init injector=#{guiceinjector}/>

<guice:injector name="guiceinjector">
<guice:modules>
<value>dk.company.servlets.ServletGuiceModule</value>
<value>com.google.inject.servlet.ServletModule</value>
</guice:modules>
</guice:injector>
`



But upon startup I get the following exception:

2008-11-27 16:29:19,310 ERROR [org.apache.catalina.core.ContainerBase] Exception sending context initialized event

Any clues to what i'm doing wrong?

In order to make the GuiceInterceptor compapitable with Seam 2.1.X, You have to implement the following method on the GuiceInterceptor class and build the seam-guice.jar

@Override
    public boolean isInterceptorEnabled() {
       return true;
    }

Source code can be found here:

Thank you for the response. I just tried to rebuild the jar, with that method added to GuiceInterceptor.java, however I still get the same stacktrace when the application starts up.

Maybe my configuration is wrong?

Michael,

Could you please check whether the guiceinjector component is instantiated correctly? (remove <guice:init injector=#{guiceinjector}/> but leave <guice:injector.../>).

[wrzep]

Hm... second guess ;)

Do you have <guice:init injector=#{guiceinjector}/> or <guice:init injector="#{guiceinjector}"/> in your components.xml? (Mind the quotation marks) The latter is correct :)

Hi

Yes, I get:

2008-11-28 13:35:06,078 INFO  [org.jboss.seam.contexts.Contexts] starting up: guiceinjector
2008-11-28 13:35:06,093 INFO  [org.jboss.labs.seam.guice.Injector] Creating injector ''from modules: [dk.company.tacs.servlets.ServletGuiceModule, com.google.inject.servlet.ServletModule]

When commenting out

<guice:init injector="#{guiceinjector}"/>

[legart]

The qoutes are there, not sure why they disappeared from the first post.

[wrzep]

<guice:init name="org.jboss.labs.seam.guice.init" class="org.jboss.labs.seam.guice.GuiceInit" injector="#{guiceinjector}"/> might be a workaround then.

That solved the problem. Many thanks!
