getPageContext
public PageContext getPageContext(javax.servlet.Servlet servlet, javax.servlet.ServletRequest request, javax.servlet.ServletResponse response, String errorPageURL, boolean needsSession, int bufferSize, boolean autoflush) Description copied from class: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 classJspFactory
- Parameters:
servlet
- the requesting servletrequest
- the current request pending on the servletresponse
- the current response pending on the servleterrorPageURL
- the URL of the error page for the requesting JSP, or nullneedsSession
- true if the JSP participates in a sessionbufferSize
- 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
Description copied from class: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 classJspFactory
- Parameters:
pc
- A PageContext previously obtained by getPageContext()
-
getEngineInfo
Description copied from class:JspFactory
called to get implementation-specific information on the current JSP engine.
- Specified by:
getEngineInfo
in classJspFactory
- Returns:
- a JspEngineInfo object describing the current JSP engine
-
