Uses of ServletException in javax.servlet
 

Subclasses of ServletException in javax.servlet
 class UnavailableException
          Defines an exception that a servlet or filter throws to indicate that it is permanently or temporarily unavailable.
 

Methods in javax.servlet that throw ServletException
 void GenericServlet.init(ServletConfig config)
          Called by the servlet container to indicate to a servlet that the servlet is being placed into service.
 void GenericServlet.init()
          A convenience method which can be overridden so that there's no need to call super.init(config).
abstract  void GenericServlet.service(ServletRequest req, ServletResponse res)
          Called by the servlet container to allow the servlet to respond to a request.
 Servlet ServletContext.getServlet(java.lang.String name)
          Deprecated. As of Java Servlet API 2.1, with no direct replacement.

This method was originally defined to retrieve a servlet from a ServletContext. In this version, this method always returns null and remains only to preserve binary compatibility. This method will be permanently removed in a future version of the Java Servlet API.

In lieu of this method, servlets can share information using the ServletContext class and can perform shared business logic by invoking methods on common non-servlet classes.

 void Servlet.init(ServletConfig config)
          Called by the servlet container to indicate to a servlet that the servlet is being placed into service.
 void Servlet.service(ServletRequest req, ServletResponse res)
          Called by the servlet container to allow the servlet to respond to a request.
 void RequestDispatcher.forward(ServletRequest request, ServletResponse response)
          Forwards a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server.
 void RequestDispatcher.include(ServletRequest request, ServletResponse response)
          Includes the content of a resource (servlet, JSP page, HTML file) in the response.
 void FilterChain.doFilter(ServletRequest request, ServletResponse response)
          Causes the next filter in the chain to be invoked, or if the calling filter is the last filter in the chain, causes the resource at the end of the chain to be invoked.
 void Filter.init(FilterConfig filterConfig)
          Called by the web container to indicate to a filter that it is being placed into service.
 void Filter.doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
          The doFilter method of the Filter is called by the container each time a request/response pair is passed through the chain due to a client request for a resource at the end of the chain.
 

Uses of ServletException in javax.servlet.http
 

Methods in javax.servlet.http that throw ServletException
protected  void HttpServlet.doGet(HttpServletRequest req, HttpServletResponse resp)
          Called by the server (via the service method) to allow a servlet to handle a GET request.
protected  void HttpServlet.doHead(HttpServletRequest req, HttpServletResponse resp)
          Receives an HTTP HEAD request from the protected service method and handles the request.
protected  void HttpServlet.doPost(HttpServletRequest req, HttpServletResponse resp)
          Called by the server (via the service method) to allow a servlet to handle a POST request.
protected  void HttpServlet.doPut(HttpServletRequest req, HttpServletResponse resp)
          Called by the server (via the service method) to allow a servlet to handle a PUT request.
protected  void HttpServlet.doDelete(HttpServletRequest req, HttpServletResponse resp)
          Called by the server (via the service method) to allow a servlet to handle a DELETE request.
protected  void HttpServlet.doOptions(HttpServletRequest req, HttpServletResponse resp)
          Called by the server (via the service method) to allow a servlet to handle a OPTIONS request.
protected  void HttpServlet.doTrace(HttpServletRequest req, HttpServletResponse resp)
          Called by the server (via the service method) to allow a servlet to handle a TRACE request.
protected  void HttpServlet.service(HttpServletRequest req, HttpServletResponse resp)
          Receives standard HTTP requests from the public service method and dispatches them to the doXXX methods defined in this class.
 void HttpServlet.service(ServletRequest req, ServletResponse res)
          Dispatches client requests to the protected service method.
 

Uses of ServletException in javax.servlet.jsp
 

Methods in javax.servlet.jsp that throw ServletException
abstract  void PageContext.forward(java.lang.String relativeUrlPath)
           This method is used to re-direct, or "forward" the current ServletRequest and ServletResponse to another active component in the application.
abstract  void PageContext.include(java.lang.String relativeUrlPath)
           Causes the resource specified to be processed as part of the current ServletRequest and ServletResponse being processed by the calling Thread.
abstract  void PageContext.handlePageException(java.lang.Exception e)
           This method is intended to process an unhandled "page" level exception by redirecting the exception to either the specified error page for this JSP, or if none was specified, to perform some implementation dependent action.
abstract  void PageContext.handlePageException(java.lang.Throwable t)
           This method is identical to the handlePageException(Exception), except that it accepts a Throwable.
