Error loading context: unknown protocol: jndi

[graeder]

I'm trying to use ContextSingletonBeanFactoryLocator for a shared factory. However, when I try load the context I get the following error:

Caused by: org.springframework.context.ApplicationContextException: I/O error parsing XML document for application context [org.springframework.context.support.ClassPathXmlApplicationContext;hashCode=536608]; nested exception is java.net.MalformedURLException: unknown protocol: jndi

It seems it has a problem with the jndi refs in the context I'm trying to reference. The weird thing is that I've been using this context file all along, just not via ContextSingletonBeanFactoryLocator.

Can you post the problematic configuration?

I'm running on oc4j 10.1.2

I can create a new ClassPathXmlApplicationContext no problem with applicationContext_ejb.xml. Isn't this what ContextSingletonBeanFactoryLocator does?

Thanks alot.

[graeder]

Oh, and here's my code to load the appContext:

public class BeanFactoryUtil {
    
    private static final BeanFactoryLocator locator;
    private static final BeanFactoryReference ref;
    private static final BeanFactory beanFactory;
    private static Logger logger = Logger.getLogger(SkillObjectFactory.class);
    
    static {
        logger.info("Loading ContextSingletonBeanFactoryLocator...");
        locator = ContextSingletonBeanFactoryLocator.getInstance();
        logger.info("Loading ejb-context...");
        ref = locator.useBeanFactory("ejb-context");
        logger.info("Loading beanFactory...");
        beanFactory = ref.getFactory();
    }
    
    public static BeanFactory getBeanFactory() {
        return beanFactory;
    }
}

[graeder]

It must be prepending the value with jndi://. Is there a workaround?

[graeder]

bumping. can anyone provide some insight on this?

[graeder]

Well, I've tried everything and can't solve the problem. It appears that there was an issue with this (key: SPR-322) that I found via Google. It also appeared that the problem was supposed to be fixed, but I just can't get it to work.

[Chris]

This is looks like a known defect in OC4J 10.1.2, see SPR-665:

http://opensource.atlassian.com/proj...browse/SPR-665

[graeder]

It doesn't surprise me actually. We've had so many headaches with OC4J. Thanks for the reply.

[Chris]

I have worked-arround this issue by modifying org.springframework.beans.factory.access.Singleton BeanFactoryLocator and then replacing the default bean factory locator in org.springframework.ejb.support.AbstractStatelessS essionBean.

We are a few months from deploying a Spring based app to OC4J 10.1.2, is there anything in particular I should watch out for?

thanks,
Chris
