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 `do` XXX 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.
`void` `HttpJspPage._jspService(HttpServletRequest request, HttpServletResponse response)` The _jspService()method corresponds to the body of the JSP page.
