Specified by: clearElementLock in interface atg.nucleus.ConfigurationLockRegistry See Also: ConfigurationLockRegistry.clearElementLock(ComponentName) getContext public javax.servlet.ServletContext getContext(java.lang.String uripath) Returns a ServletContext object that corresponds to a specified URL on the server. This method allows servlets to gain access to the resources located at a specified URL and obtain RequestDispatcher objects from it. In security conscious environments, the servlet engine can return null for a given URL. Specified by: getContext in interface javax.servlet.ServletContext Parameters: uripath - a String specifying the URL for which you are requesting a ServletContext object Returns: the ServletContext object that corresponds to the named URL See Also: RequestDispatcher getMajorVersion public int getMajorVersion() Returns the major version of the Java Servlet API that this Web server supports. All implementations that comply with Version 2.1 must have this method return the integer 2. Specified by: getMajorVersion in interface javax.servlet.ServletContext Returns: 2 getMinorVersion public int getMinorVersion() Returns the minor version of the Servlet API that this Web server supports. All implementations that comply with Version 2.2 must have this method return the integer 2. Specified by: getMinorVersion in interface javax.servlet.ServletContext Returns: 2 getResource public java.net.URL getResource(java.lang.String pPath) throws java.net.MalformedURLException Returns the resource that is mapped to a specified path. The path must be in the form /dir/dir/file.ext. This method allows the Web server to make a resource available to a servlet from any source. Resources can be located on a local or remote file system, in a database, or on a remote network site. This method can return null if no resource is mapped to the pathname. The servlet engine must implement the URL handlers and URLConnection objects that are necessary to access the resource. This method has a different purpose than java.lang.Class.getResource, which looks up resources based on a class loader. This method does not use class loaders. Specified by: getResource in interface javax.servlet.ServletContext Parameters: pPath - a String specifying the path to the resource, in the form /dir/dir/file.ext Returns: the resource located at the named path, or null if there is no resource at that path Throws: java.net.MalformedURLException - if the pathname is not given in the correct form getResourceAsStream public java.io.InputStream getResourceAsStream(java.lang.String pPath) Returns the resource located at the named path as an InputStream object. The data in the InputStream can be of any type or length. The path must be of the form /dir/dir/file.ext. This method returns null if no resource exists at the specified path. Metainformation such as content length and content type that is available when you use the getResource method is lost when you use this method. The servlet engine must implement the URL handlers and URLConnection objects necessary to access the resource. This method is different from java.lang.Class.getResourceAsStream, which uses a class loader. This method allows servlet engines to make a resource available to a servlet from any location, without using a class loader. Specified by: getResourceAsStream in interface javax.servlet.ServletContext Parameters: pPath - a String specifying the path to the resource, in the form /dir/dir/file.ext Returns: the InputStream returned to the servlet, or null if no resource exists at the specified path getResourcePaths public java.util.Set getResourcePaths(java.lang.String pPath) Specified by: getResourcePaths in interface javax.servlet.ServletContext getRequestDispatcher public javax.servlet.RequestDispatcher getRequestDispatcher(java.lang.String pUrlPath) Returns a RequestDispatcher object that acts as a wrapper for the resource located at the named path. You can use a RequestDispatcher object to forward a request to the resource or include a resource in a response. The pathname must be in the form /dir/dir/file.ext. This method returns null if the ServletContext cannot return a RequestDispatcher. The servlet engine is responsible for wrapping the resource with a RequestDispatcher object. Specified by: getRequestDispatcher in interface javax.servlet.ServletContext Parameters: pUrlPath - a String specifying the pathname to the resource Returns: a RequestDispatcher object that acts as a wrapper for the resource at the path you specify See Also: RequestDispatcher getNamedDispatcher public javax.servlet.RequestDispatcher getNamedDispatcher(java.lang.String pName) GenericContext does not have any mechanism for specifying named servlets in the Servlet 2.2 sense. Specified by: getNamedDispatcher in interface javax.servlet.ServletContext getAttributeNames public java.util.Enumeration<java.lang.String> getAttributeNames() Returns an Enumeration containing the attribute names available within this servlet context. You can use the getAttribute(java.lang.String) method with an attribute name to get the value of an attribute. Specified by: getAttributeNames in interface javax.servlet.ServletContext Returns: an Enumeration of attribute names See Also: getAttribute(java.lang.String) setAttribute public void setAttribute(java.lang.String pName, java.lang.Object pObject) Gives an attribute a name in this servlet context. If the name specified is already used for an attribute, this method will overwrite the old attribute and bind the name to the new attribute. Attribute names should follow the same convention as package names. The Java Servlet API specification reserves names matching java.*, javax.*, and sun.*. Specified by: setAttribute in interface javax.servlet.ServletContext Parameters: pName - a String specifying the name of the attribute pObject - an Object representing the attribute to be given the name removeAttribute public void removeAttribute(java.lang.String pName) Removes the attribute with the given name from the servlet context. If you remove an attribute, and then use getAttribute(java.lang.String) to retrieve the attribute's value, getAttribute returns null. Specified by: removeAttribute in interface javax.servlet.ServletContext Parameters: pName - a String specifying the name of the attribute to be removed getInitParameter public java.lang.String getInitParameter(java.lang.String pName) GenericContext does not have any mechanism for specifying init params. To use this feature you must place your servlet in a Web Application. Specified by: getInitParameter in interface javax.servlet.ServletContext getInitParameterNames public java.util.Enumeration<java.lang.String> getInitParameterNames() GenericContext does not have any mechanism for specifying init params. To use this feature you must place your servlet in a Web Application. Specified by: getInitParameterNames in interface javax.servlet.ServletContext log public void log(java.lang.String pMessage, java.lang.Throwable pThrowable) Logs this message using regular nucleus logging facilities for this context Specified by: log in interface javax.servlet.ServletContext
