javax.servlet .ServletRequestWrapper

javax.servlet.http .HttpServletRequestWrapper

HttpServletRequestWrapper
public class HttpServletRequestWrapper extends ServletRequestWrapper implements HttpServletRequest(Code)
	Wraps a servlet request in another request. Filters may use ServletRequestWrapper to modify the headers passed to the servlet. The default methods just call the wrapped request methods. since: servlet 2.3

Constructor Summary
public	HttpServletRequestWrapper(HttpServletRequest request)

Method Summary
public String	getAuthType() Returns the auth type, e.g.
public String	getContextPath() Returns the part of the URI corresponding to the application's prefix.
public Cookie[]	getCookies() Returns an array of all cookies sent by the client.
public long	getDateHeader(String name) Converts a date header to milliseconds since the epoch.
public String	getHeader(String name) Returns the first value for a request header.
public Enumeration	getHeaderNames() Returns an enumeration of all headers sent by the client.
public Enumeration	getHeaders(String name) Returns all the values for a request header.
public int	getIntHeader(String name) Converts a header value to an integer.
public String	getMethod() Returns the HTTP method, e.g.
public String	getPathInfo() Returns the URI part after the selected servlet and null if there is no suffix.
public String	getPathTranslated() Returns the physical path name for the path info.
public String	getQueryString() Returns the request's query string.
public String	getRemoteUser() Returns the remote user if authenticated.
public String	getRequestURI()
public StringBuffer	getRequestURL() Reconstructs the URL the client used for the request.
public String	getRequestedSessionId() Returns the session id.
public String	getServletPath() Returns the URI part corresponding to the selected servlet.
public HttpSession	getSession(boolean create) Returns a session.
public HttpSession	getSession() Returns the current session, creating one if necessary.
public Principal	getUserPrincipal() Returns the equivalent principal object for the authenticated user.
public boolean	isRequestedSessionIdFromCookie() Returns true if the session came from a cookie.
public boolean	isRequestedSessionIdFromURL() Returns true if the session came URL-encoding.
public boolean	isRequestedSessionIdFromUrl()
public boolean	isRequestedSessionIdValid() Returns true if the session is valid.
public boolean	isUserInRole(String role) Returns true if the user is in the given role.
public void	setRequest(ServletRequest request) Sets the request object for the wrapper.

Constructor Detail

HttpServletRequestWrapper
public HttpServletRequestWrapper(HttpServletRequest request)(Code)
	Creates a new request wrapper Parameters: request - the wrapped request

Method Detail

getAuthType
public String getAuthType()(Code)
	Returns the auth type, e.g. basic.

getContextPath
public String getContextPath()(Code)
	Returns the part of the URI corresponding to the application's prefix. The first part of the URI selects applications (ServletContexts). `getContextPath()` is /myapp for the uri /myapp/servlet/Hello,

getCookies
public Cookie[] getCookies()(Code)
	Returns an array of all cookies sent by the client.

getDateHeader
public long getDateHeader(String name)(Code)
	Converts a date header to milliseconds since the epoch. `long mod = request.getDateHeader("If-Modified-Since");` Parameters: name - the header name the header value converted to an date

getHeader

public String getHeader(String name)(Code)

Returns the first value for a request header.

Corresponds to CGI's HTTP_*

 String userAgent = request.getHeader("User-Agent");

Parameters:
name - the header name the header value

getHeaderNames
public Enumeration getHeaderNames()(Code)
	Returns an enumeration of all headers sent by the client.

getHeaders
public Enumeration getHeaders(String name)(Code)
	Returns all the values for a request header. In some rare cases, like cookies, browsers may return multiple headers. Parameters: name - the header name an enumeration of the header values.

getIntHeader
public int getIntHeader(String name)(Code)
	Converts a header value to an integer. Parameters: name - the header name the header value converted to an integer

getMethod
public String getMethod()(Code)
	Returns the HTTP method, e.g. "GET" or "POST" Equivalent to CGI's `REQUEST_METHOD`

getPathInfo

public String getPathInfo()(Code)

Returns the URI part after the selected servlet and null if there is no suffix.

Corresponds to CGI's PATH_INFO

getPathInfo() is /foo for the uri /myapp/servlet/Hello/foo. getPathInfo() is /hello.jsp for for the uri /myapp/dir/hello.jsp/foo.

getPathTranslated
public String getPathTranslated()(Code)
	Returns the physical path name for the path info. Corresponds to CGI's `PATH_TRANSLATED` null if there is no path info.

getQueryString
public String getQueryString()(Code)
	Returns the request's query string. Form based servlets will use `ServletRequest.getParameter()` to decode the form values. Corresponds to CGI's `PATH_TRANSLATED`

getRemoteUser
public String getRemoteUser()(Code)
	Returns the remote user if authenticated.

getRequestURI
public String getRequestURI()(Code)
	Returns the entire request URI

getRequestURL
public StringBuffer getRequestURL()(Code)
	Reconstructs the URL the client used for the request. since: Servlet 2.3

getRequestedSessionId
public String getRequestedSessionId()(Code)
	Returns the session id. Sessions are a convenience for keeping user state across requests. The session id is the value of the JSESSION cookie.

getServletPath
public String getServletPath()(Code)
	Returns the URI part corresponding to the selected servlet. The URI is relative to the application. Corresponds to CGI's `SCRIPT_NAME` `getServletPath()` is /servlet/Hello for the uri /myapp/servlet/Hello/foo. `getServletPath()` is /dir/hello.jsp for the uri /myapp/dir/hello.jsp/foo,

getSession
public HttpSession getSession(boolean create)(Code)
	Returns a session. If no session exists and create is true, then create a new session, otherwise return null. Parameters: create - If true, then create a new session if none exists.

getSession
public HttpSession getSession()(Code)
	Returns the current session, creating one if necessary. Sessions are a convenience for keeping user state across requests.

getUserPrincipal
public Principal getUserPrincipal()(Code)
	Returns the equivalent principal object for the authenticated user.

isRequestedSessionIdFromCookie
public boolean isRequestedSessionIdFromCookie()(Code)
	Returns true if the session came from a cookie.

isRequestedSessionIdFromURL
public boolean isRequestedSessionIdFromURL()(Code)
	Returns true if the session came URL-encoding.

isRequestedSessionIdFromUrl
public boolean isRequestedSessionIdFromUrl()(Code)

isRequestedSessionIdValid
public boolean isRequestedSessionIdValid()(Code)
	Returns true if the session is valid.

isUserInRole
public boolean isUserInRole(String role)(Code)
	Returns true if the user is in the given role.

setRequest
public void setRequest(ServletRequest request)(Code)
	Sets the request object for the wrapper. Parameters: request - the wrapped request
