public class JspServlet

extends javax.servlet.http.HttpServlet

The JSP engine (a.k.a Jasper). The servlet container is responsible for providing a URLClassLoader for the web application context Jasper is being used in. Jasper will try get the Tomcat ServletContext attribute for its ServletContext class loader, if that fails, it uses the parent class loader. In either case, it must be a URLClassLoader.

Constructor Detail

JspServlet

public JspServlet()

Method Detail

init

public 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)>Servlet.init(javax.servlet.ServletConfig) 55 .

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

---

getJspCount

public int getJspCount()

Returns the number of JSPs for which JspServletWrappers exist, i.e., the number of JSPs that have been loaded into the webapp with which this JspServlet is associated.

This info may be used for monitoring purposes.

---

setJspReloadCount

public void setJspReloadCount(int count)

Resets the JSP reload counter.

---

getJspReloadCount

public int getJspReloadCount()

Gets the number of JSPs that have been reloaded.

This info may be used for monitoring purposes.

---

preCompile

boolean preCompile(javax.servlet.http.HttpServletRequest request)
             throws javax.servlet.ServletException

Look for a precompilation request as described in Section 8.4.2 of the JSP 1.2 Specification. WARNING - we cannot use request.getParameter() for this, because that will trigger parsing all of the request parameters, and not give a servlet the opportunity to call request.setCharacterEncoding() first.

---

service

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

Description copied from class: javax.servlet.http.HttpServlet

Receives standard HTTP requests from the public service method and dispatches them to the doXXX methods defined in this class. This method is an HTTP-specific version of the Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse)>Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) 55 method. There's no need to override this method.

---

destroy

public 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()>Servlet.destroy() 55 .

---

serviceJspFile

private void serviceJspFile(javax.servlet.http.HttpServletRequest request,
                            javax.servlet.http.HttpServletResponse response,
                            java.lang.String jspUri,
                            java.lang.Throwable exception,
                            boolean precompile)
                     throws javax.servlet.ServletException,
                            java.io.IOException
