[jboss-dev-forums] [Design of POJO Server] - ProfileService/OBR repository

[scott.stark@jboss.org]

I just checked in a OSGi OBR like addition to the org.jboss.profileservice.spi.repository package. The interfaces in there mirror the OSGi OBR interfaces with two additions:

1. The RepositoryAdmin has an additional Repository getRepository(URI repository) throws Exception; method.
2. There is an extension of the Repository interface that allows for addition/removal and modification detection of Resources:


  | public interface MutableRepository extends Repository
  | {
  |    /** */
  |    public enum ModifyStatus {ADDED, MODIFIED, REMOVED};
  | 
  |    /**
  |     * Add a resource to the repository.
  |     * @param resource the resource to add
  |     * @throws Exception thrown on any addition failure
  |     */
  |    public void addResource(Resource resource)
  |       throws Exception;
  |    /**
  |     * Remove a resource from the repository
  |     * @param name the resource SYMBOLIC_NAME or ID
  |     * @return the Resource that was removed if found, null otherwise.
  |     * @throws Exception thrown on any remove failure
  |     */
  |    public Resource removeResource(String name)
  |       throws Exception;
  |    /**
  |     * Return a collection of resources that have been modified since
  |     * the last call to this method. The returned resources contain
  |     * a modifyStatus property of type ModifyStatus to indicate the
  |     * type of change.
  |     * 
  |     * @return The Resources that have been modified.
  |     * @throws Exception
  |     */
  |    public Collection<Resource> getModifiedResources()
  |       throws Exception;
  | }
  | 

There are still a lot of issues to validate in terms of actually using an OBR implementation. The validation of the OBR like API is in the mapping class org.jboss.system.server.profileservice.repository.RepositoryAdminAdaptor. This maps the current org.jboss.profileservice.spi.DeploymentRepository spi onto the org.jboss.profileservice.spi.repository.RepositoryAdmin OBR like SPI. I'm going to look at using some form of the Felix 1.1 bundlerepository code(http://svn.apache.org/repos/asf/felix/trunk/bundlerepository/) for the next release.
