protected HttpJspBase()
Method Detail

init

public final void init(javax.servlet.ServletConfig config)
                throws javax.servlet.ServletException
Description copied from class: javax.servlet.GenericServlet
Called by the servlet container to indicate to a servlet that the servlet is being placed into service. See Servlet.init(javax.servlet.ServletConfig).

This implementation stores the ServletConfig object it receives from the servlet container for later use. When overriding this form of the method, call super.init(config).

Specified by:
init in interface javax.servlet.Servlet
Overrides:
init in class javax.servlet.GenericServlet
Parameters:
config - the ServletConfig object that contains configutation information for this servlet
Throws:
javax.servlet.ServletException - if an exception occurs that interrupts the servlet's normal operation
See Also:
UnavailableException

getServletInfo

public java.lang.String getServletInfo()
Description copied from class: javax.servlet.GenericServlet
Returns information about the servlet, such as author, version, and copyright. By default, this method returns an empty string. Override this method to have it return a meaningful value. See Servlet.getServletInfo().

Specified by:
getServletInfo in interface javax.servlet.Servlet
Overrides:
getServletInfo in class javax.servlet.GenericServlet
Returns:
String information about this servlet, by default an empty string

destroy

public final void destroy()
Description copied from class: javax.servlet.GenericServlet
Called by the servlet container to indicate to a servlet that the servlet is being taken out of service. See Servlet.destroy().

Specified by:
destroy in interface javax.servlet.Servlet
Overrides:
destroy in class javax.servlet.GenericServlet

service

public final void service(javax.servlet.http.HttpServletRequest request,
                          javax.servlet.http.HttpServletResponse response)
                   throws javax.servlet.ServletException,
                          java.io.IOException
Entry point into service.

Overrides:
service in class javax.servlet.http.HttpServlet
Parameters:
request - the HttpServletRequest object that contains the request the client made of the servlet
response - the HttpServletResponse object that contains the response the servlet returns to the client
Throws:
javax.servlet.ServletException - if the HTTP request cannot be handled
java.io.IOException - if an input or output error occurs while the servlet is handling the HTTP request
See Also:
Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse)

jspInit

public void jspInit()
Description copied from interface: javax.servlet.jsp.JspPage
The jspInit() method is invoked when the JSP page is initialized. It is the responsibility of the JSP implementation (and of the class mentioned by the extends attribute, if present) that at this point invocations to the getServletConfig() method will return the desired value. A JSP page can override this method by including a definition for it in a declaration element. A JSP page should redefine the init() method from Servlet.

Specified by:
jspInit in interface javax.servlet.jsp.JspPage

_jspInit

public void _jspInit()

jspDestroy

public void jspDestroy()
Description copied from interface: javax.servlet.jsp.JspPage
The jspDestroy() method is invoked when the JSP page is about to be destroyed. A JSP page can override this method by including a definition for it in a declaration element. A JSP page should redefine the destroy() method from Servlet.

Specified by:
jspDestroy in interface javax.servlet.jsp.JspPage

_jspDestroy

protected void _jspDestroy()

_jspService

public abstract void _jspService(javax.servlet.http.HttpServletRequest request,
                                 javax.servlet.http.HttpServletResponse response)
                          throws javax.servlet.ServletException,
                                 java.io.IOException
Description copied from interface: javax.servlet.jsp.HttpJspPage
The _jspService()method corresponds to the body of the JSP page. This method is defined automatically by the JSP container and should never be defined by the JSP page author.

If a superclass is specified using the extends attribute, that superclass may choose to perform some actions in its service() method before or after calling the _jspService() method. See using the extends attribute in the JSP_Engine chapter of the JSP specification.

Specified by:
_jspService in interface javax.servlet.jsp.HttpJspPage
Parameters:
request - Provides client request information to the JSP.
response - Assists the JSP in sending a response to the client.
Throws:
javax.servlet.ServletException - Thrown if an error occurred during the processing of the JSP and that the container should take appropriate action to clean up the request.
java.io.IOException - Thrown if an error occurred while writing the response for this page.
