Re: NoClassDefFoundError on OCM Test

[Fernando Cabredo]

The problem is now resolved. I googlednet/sf/cglib/proxy/Callback and found the 
missing jar file.

Regards to everyone.

Subject: NoClassDefFoundError on OCM Test

Hi,

I would like to get some help that is causing my OCM test. 

Here is the error:

Exception in thread "main" java.lang.NoClassDefFoundError:

org.apache.jackrabbit.ocm.manager.impl.ObjectContentManagerImpl.<init>(ObjectContentManagerImpl.java:125)

        Article article = new Article();
        article.setPath("/articles");
        article.setTitle("Public Announcement");
        article.setContent("Urgently Needed");
        article.setAuthorid(100);
        article.setSectionid(1);
        article.setDatecreated(new Date());
        ocm.insert(article);
        ocm.save();
        
        System.out.println("Retrieve a press release from the repository");
        article = (Article) ocm.getObject("/articles");
        System.out.println("Article title : " + article.getTitle());
    }
    
}

Any help will be much appreciated.
