                                                    javax.servlet.ServletRequest request,

                                                    boolean autoflush)

Description copied from class: javax.servlet.jsp.JspFactory

obtains an instance of an implementation dependent javax.servlet.jsp.PageContext abstract class for the calling Servlet and currently pending request and response.

This method is typically called early in the processing of the _jspService() method of a JSP implementation class in order to obtain a PageContext object for the request being processed.

Invoking this method shall result in the PageContext.initialize() method being invoked. The PageContext returned is properly initialized.

All PageContext objects obtained via this method shall be released by invoking releasePageContext().

Specified by:

getPageContext in class javax.servlet.jsp.JspFactory

Parameters:

servlet - the requesting servlet

request - the current request pending on the servlet

response - the current response pending on the servlet

errorPageURL - the URL of the error page for the requesting JSP, or null

needsSession - true if the JSP participates in a session

bufferSize - size of buffer in bytes, PageContext.NO_BUFFER if no buffer, PageContext.DEFAULT_BUFFER if implementation default.

autoflush - should the buffer autoflush to the output stream on buffer overflow, or throw an IOException?

Returns:

the page context

releasePageContext

public void releasePageContext(javax.servlet.jsp.PageContext pc)

Description copied from class: javax.servlet.jsp.JspFactory

called to release a previously allocated PageContext object. Results in PageContext.release() being invoked. This method should be invoked prior to returning from the _jspService() method of a JSP implementation class.

Specified by:

releasePageContext in class javax.servlet.jsp.JspFactory

Parameters:

pc - A PageContext previously obtained by getPageContext()

getEngineInfo

public javax.servlet.jsp.JspEngineInfo getEngineInfo()

Description copied from class: javax.servlet.jsp.JspFactory

called to get implementation-specific information on the current JSP engine.

Specified by:

getEngineInfo in class javax.servlet.jsp.JspFactory

Returns:

a JspEngineInfo object describing the current JSP engine

getJspApplicationContext

public javax.servlet.jsp.JspApplicationContext getJspApplicationContext(javax.servlet.ServletContext context)

Description copied from class: javax.servlet.jsp.JspFactory

Obtains the JspApplicationContext instance associated with the web application for the given ServletContext.

Specified by:

getJspApplicationContext in class javax.servlet.jsp.JspFactory

Parameters:

context - The ServletContext for the web application the desired JspApplicationContext is associated with.

Returns:

The JspApplicationContext associated with the web application.
