Constructor Details

ServletWebContext

public ServletWebContext()

Construct an uninitialized ServletWebContext instance.

ServletWebContext

public ServletWebContext(javax.servlet.ServletContext context,
 javax.servlet.http.HttpServletRequest request,
 javax.servlet.http.HttpServletResponse response)

Construct a ServletWebContext instance that is initialized with the specified Servlet API objects.

Parameters:

context - The ServletContext for this web application

request - The HttpServletRequest for this request

response - The HttpServletResponse for this request

Method Details

getContext

public javax.servlet.ServletContext getContext()

Return the ServletContext for this context.

Returns:

The ServletContext for this context.

getRequest

public javax.servlet.http.HttpServletRequest getRequest()

Return the HttpServletRequest for this context.

The HttpServletResponse for this context.

initialize

public void initialize(javax.servlet.ServletContext context,
 javax.servlet.http.HttpServletRequest request,
 javax.servlet.http.HttpServletResponse response)
