Incorrect file being used to create JarVisitor from VFS3 URLs
-------------------------------------------------------------

                 Key: JBJPA-23
                 URL: https://jira.jboss.org/jira/browse/JBJPA-23
             Project: JBoss JPA
          Issue Type: Bug
          Components: deployers
    Affects Versions: 1.0.1
            Reporter: John Bailey
            Assignee: John Bailey


There is a problem with the JarVIsitor being created by org.hibernate.ejb.EJB3Configuration for VFS3 file: urls.  The main problem is the JarVisitorFactory is calling URL.getFile and then attempting to use a JDK file pointed at a nested JAR file.  This fails as the File points to in an invalid File path. 

 This can be fixed in a couple different ways:
1. JPA deployers can pass an absolute URL to the JAR file on the filesystem into the EJB3Configuration.  This is inefficient as it will create a JarFile and unzip the jar file, which has already been scanned by VFS.  
2.  Pass in a the absolute URL to the temporary directory for the mounted jar.  This would save from second JarFile creation, but will not always work as there is no guarantee the file system is fully populated in the temp filesystem.   So this would require the temp file system to be forcefully populated from the VFS zip mount.


So for now, we will have to go with the option 1 and pass the fully path to the jar file.
