| /** |
| * Proxy for a repository bound in servlet context. The configured repository |
| * attribute is looked up from the servlet context during each method call. |
| * Thus the repository does not need to exist when this class is instantiated. |
| * The repository can also be replaced with another repository during the |
| * lifetime of an instance of this class. |
| * <p> |
| * A typical way to use this class would be: |
| * <pre> |
| * public class MyServlet extends HttpServlet { |
| * |
| * private final Repository repository = new ServletRepository(this); |
| * |
| * protected void doGet( |
| * HttpServletRequest request, HttpServletResponse response) |
| * throws ServletException, IOException { |
| * try { |
| * Session session = repository.login(); |
| * try { |
| * ...; |
| * } finally { |
| * session.logout(); |
| * } |
| * } catch (RepositoryException e) { |
| * throw new ServletException(e); |
| * } |
| * } |
| * |
| * } |
| * </pre> |
| * <p> |
| * Starting with version 1.6 this class can also be used by a servlet filter: |
| * <pre> |
| * public class MyFilter implements Filter { |
| * |
| * private Repository repository; |
| * |
| * public void init(FilterConfig config) { |
| * repository = new ServletRepository(config); |
| * } |
| * |
| * // ... |
| * |
| * } |
| * </pre> |

| * @since 1.4 |
| * @see ServletRepositoryFactory |
