Examples with Repository javax.jcr.Repository used on opensource projects

Example 66 with Repository

use of javax.jcr.Repository in project jackrabbit by apache.

the class AbstractRepositoryServlet method doGet.

/**
     * Outputs the repository descriptors either as a collection of properties
     * (see {@link Properties#store(java.io.OutputStream, String)} or
     * individually addressable text/plain resources based on the request URI.
     * <p>
     * A typical mapping for a repository servlet would be:
     * <pre>
     * &lt;servlet-mapping&gt;
     *   &lt;servlet-name&gt;Repository&lt;/servlet-name&gt;
     *   &lt;url-pattern&gt;/repository/*&lt;/url-pattern&gt;
     * &lt;/servlet-mapping&gt;
     * </pre>
     * <p>
     * This mapping would allow clients to retrieve all repository descriptors
     * from <code>http://server/context/repository/</code> and to address
     * individual descriptors by key with URIs like
     * <code>http://server/context/repository/<i>key</i></code>.
     * For example, the name of the repository vendor could be retrieved from
     * <code>http://server/context/repository/jcr.repository.vendor</code>.
     * Likewise, a 404 (not found) response from
     * <code>http://server/context/repository/level.2.supported</code> would
     * indicate that the repository does not support Level 2 features.
     * <p>
     * Note that mapping a repository servlet to the URL space is optional,
     * as the main purpose of the servlet is to make a repository available
     * in the servlet context, not to expose repository information to web
     * clients.
     *
     * @param request HTTP request
     * @param response HTTP response
     * @throws IOException on IO errors
     * @throws ServletException on servlet errors
