Hi, The exception you sent indicates that the problem is on line 171 of JackrabbitBlogEntryDAO.java, within the getBlogEntry method. The method you sent is getBlogEntryNode, not getBlogEntry. Even if you had sent the correct method body, without line number information it is hard to identify what the incorrect line is.
Moreover, this really doesn't look like a Jackrabbit issue as your stack traces contain no org.apache.jackrabbit classes. I suspect you simply have an error in your code. Check out what you have on line 171 and trace back all the references used on that line. BR, Jukka Zitting
