All the basic HTTP requests are handled by the * DefaultServlet. The WebDAVServlet must not be used as the default servlet (ie mapped to '/') as it will not work in * this configuration. * <p> * Mapping a subpath (e.g. <code>/webdav/*</code> to this servlet has the effect of re-mounting the entire web * application under that sub-path, with WebDAV access to all the resources. The <code>WEB-INF</code> and * <code>META-INF</code> directories are protected in this re-mounted resource tree. * <p> * To enable WebDAV for a context add the following to web.xml: * * <pre> * &lt;servlet&gt; * &lt;servlet-name&gt;webdav&lt;/servlet-name&gt; * &lt;servlet-class&gt;org.apache.catalina.servlets.WebdavServlet&lt;/servlet-class&gt; * &lt;init-param&gt; * &lt;param-name&gt;debug&lt;/param-name&gt; * &lt;param-value&gt;0&lt;/param-value&gt; * &lt;/init-param&gt; * &lt;init-param&gt; * &lt;param-name&gt;listings&lt;/param-name&gt; * &lt;param-value&gt;false&lt;/param-value&gt; * &lt;/init-param&gt; * &lt;/servlet&gt; * &lt;servlet-mapping&gt; * &lt;servlet-name&gt;webdav&lt;/servlet-name&gt; * &lt;url-pattern&gt;/*&lt;/url-pattern&gt; * &lt;/servlet-mapping&gt; * </pre> * * This will enable read only access. To enable read-write access add: * * <pre> * &lt;init-param&gt; * &lt;param-name&gt;readonly&lt;/param-name&gt; * &lt;param-value&gt;false&lt;/param-value&gt; * &lt;/init-param&gt; * </pre> * * To make the content editable via a different URL, use the following mapping: * * <pre> * &lt;servlet-mapping&gt; * &lt;servlet-name&gt;webdav&lt;/servlet-name&gt; * &lt;url-pattern&gt;/webdavedit/*&lt;/url-pattern&gt; * &lt;/servlet-mapping&gt; * </pre> * * By default access to /WEB-INF and META-INF are not available via WebDAV. To enable access to these URLs, use add: * * <pre> * &lt;init-param&gt; * &lt;param-name&gt;allowSpecialPaths&lt;/param-name&gt; * &lt;param-value&gt;true&lt;/param-value&gt; * &lt;/init-param&gt; * </pre> * * Don't forget to secure access appropriately to the editing URLs, especially if allowSpecialPaths is used. With the * mapping configuration above, the context will be accessible to normal users as before. Those users with the necessary * access will be able to edit content available via http://host:port/context/content using * http://host:port/context/webdavedit/content * * @author Remy Maucherat * * @see <a href="https://tools.ietf.org/html/rfc4918">RFC 4918</a> */ public class WebdavServlet extends DefaultServlet { @Serial private static final long serialVersionUID = 1L; // -------------------------------------------------------------- Constants private static final String METHOD_PROPFIND = "PROPFIND"; private static final String METHOD_PROPPATCH = "PROPPATCH"; private static final String METHOD_MKCOL = "MKCOL"; private static final String METHOD_COPY = "COPY"; private static final String METHOD_MOVE = "MOVE"; private static final String METHOD_LOCK = "LOCK"; private static final String METHOD_UNLOCK = "UNLOCK"; /** * PROPFIND - Specify a property mask. */ private static final int FIND_BY_PROPERTY = 0; /** * PROPFIND - Display all properties. */ private static final int FIND_ALL_PROP = 1; /** * PROPFIND - Return property names. */ private static final int FIND_PROPERTY_NAMES = 2; /** * Create a new lock. */ private static final int LOCK_CREATION = 0; /** * Refresh lock. */ private static final int LOCK_REFRESH = 1; /** * Default lock timeout value. */ private static final int DEFAULT_TIMEOUT = 3600; /** * Maximum lock timeout. */ private static final int MAX_TIMEOUT = 604800; /** * Default namespace. */ protected static final String DEFAULT_NAMESPACE = "DAV:"; /** * Simple date format for the creation date ISO representation (partial). */ protected static final ConcurrentDateFormat creationDateFormat = new ConcurrentDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US, TimeZone.getTimeZone("GMT")); // ----------------------------------------------------- Instance Variables /** * Repository of the locks put on single resources. * <p> * Key : path <br> * Value : LockInfo */ private final Map<String,LockInfo> resourceLocks = new ConcurrentHashMap<>(); /** * Repository of the lock-null resources. * <p> * Key : path of the collection containing the lock-null resource<br> * Value : List of lock-null resource which are members of the collection.
