getPageContext

public javax.servlet.jsp.PageContext getPageContext(javax.servlet.Servlet servlet,
                                                    javax.servlet.ServletRequest request,
                                                    javax.servlet.ServletResponse response,
                                                    java.lang.String errorPageURL,

                                                    int bufferSize,
                                                    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, JspWriter.NO_BUFFER if no buffer, JspWriter.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

Obtain the JspApplicationContext instance that was associated within the passed ServletContext for this web application.

Specified by:
getJspApplicationContext in class javax.servlet.jsp.JspFactory
Parameters:
context - the current web application's ServletContext
Returns:
JspApplicationContext instance
