    Header

    A Persistence Bundle is a bundle that contains the Meta-Persistence header. If this header is not present, then this specification does not apply and a JPA Provider should ignore the corresponding bundle.

    /**
     * Verify the Meta-Persistence header
     * 
     * @throws Exception
     */
    
    public void verifyMetaPersistence() throws Exception {
    	List<String> list = new ArrayList<String>();
    	String mp = dot.getManifest().getMainAttributes().getValue(META_PERSISTENCE);
    	for (String location : OSGiHeader.parseHeader(mp).keySet()) {
    		String[] parts = location.split("!/");
    
    		Resource resource = dot.getResource(parts[0]);
    		if (resource == null)
    			list.add(location);
    		else {
    			if (parts.length > 1) {
    				Jar jar = new Jar("", resource.openInputStream());
    				try {
    					resource = jar.getResource(parts[1]);
    					if (resource == null)
    						list.add(location);
    				}
    				catch (Exception e) {
    					list.add(location);
    				}
    				finally {
    					jar.close();
    				}
    			}
    		}
    	}
    	if (list.isEmpty())
    		return;
    
    	error(Constants.META_PERSISTENCE + " refers to resources not in the bundle: %s", list).header(Constants.META_PERSISTENCE);
    }
