Constructor Details

JspFactory

public JspFactory()

Sole constructor. (For invocation by subclass constructors, typically implicit.)

Method Details

setDefaultFactory

public static void setDefaultFactory(JspFactory deflt)

Sets the default factory for this implementation. It is illegal for any principal other than the JSP Engine runtime to call this method.

Parameters:

deflt - The default factory implementation

getDefaultFactory

public static JspFactory getDefaultFactory()

Returns the default factory for this implementation.

Returns:

the default factory for this implementation

getPageContext

public abstract PageContext getPageContext(javax.servlet.Servlet servlet,
 javax.servlet.ServletRequest request,
 javax.servlet.ServletResponse response,
 String errorPageURL,
 boolean needsSession,
 int bufferSize,
 boolean autoFlush)

Obtain an instance of a PageContext class implementation for use by the calling Servlet and base implementation.

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 - the buffer size from the page directive, or 8192

autoFlush - whether the buffer should be auto flushed

Returns:

A valid PageContext instance for use by the calling servlet.

releasePageContext

public abstract void releasePageContext(PageContext pc)

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.

Parameters:

pc - A PageContext previously obtained by getPageContext()
