Returns the name of the character encoding used in the body of this request. This method returns null if the request does not specify a character encoding
Type
String a String containing the name of the character encoding, or null if the request does not specify a character encoding
Returns the length, in bytes, of the request body and made available by the input stream, or -1 if the length is not known. For HTTP servlets, same as the value of the CGI variable CONTENT_LENGTH.
Returns: Number a long containing the length of the request body or -1L if the length is not known
Returns the MIME type of the body of the request, or null if the type is not known. For HTTP servlets, same as the value of the CGI variable CONTENT_TYPE.
Returns: String a String containing the name of the MIME type of the request, or null if the type is not known
Get raw the contents of the request.
In case of multipart request, all uploaded items are listed separately. In case of a request with a single body, the contents array consists of one item, the body.
This method returns an empty array if the request has no contents.
Returns: Array an array of WsContents objects.
Sample
Returns the portion of the request URI that indicates the context of the request. The context path always comes first in a request URI. The path starts with a "/" character but does not end with a "/" character. For servlets in the default (root) context, this method returns "". The container does not decode this string.
It is possible that a servlet container may match a context by more than one context path. In such cases this method will return the actual context path used by the request and it may differ from the path returned by the javax.servlet.ServletContext#getContextPath() method. The context path returned by javax.servlet.ServletContext#getContextPath() should be considered as the prime or preferred context path of the application.
Returns: String a String specifying the portion of the request URI that indicates the context of the request
Returns an array containing all of the Cookie objects the client sent with this request. This method returns an empty array if no cookies were sent.
Returns: Array an array of all the Cookies included with this request
Returns the value of the specified request header as a long value that represents a Date object. Use this method with headers that contain dates, such as If-Modified-Since.
The date is returned as the number of milliseconds since January 1, 1970 GMT. The header name is case insensitive.
If the request did not have a header of the specified name, this method returns -1. If the header can't be converted to a date, the method throws an IllegalArgumentException.
Parameters
String name a String specifying the name of the header
Returns: Number a long value representing the date specified in the header expressed as the number of milliseconds since January 1, 1970 GMT, or -1 if the named header was not included with the request
Returns the value of the specified request header as a String. If the request did not include a header of the specified name, this method returns null. If there are multiple headers with the same name, this method returns the first head in the request. The header name is case insensitive. You can use this method with any request header.
Parameters
String name The name of the header to get
Returns: String
Sample
Returns an enumeration of all the header names this request contains. If the request has no headers, this method returns an empty enumeration.
Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null
Returns: Array an enumeration of all the header names sent with this request; if the request has no headers, an empty enumeration; if the servlet container does not allow servlets to use this method, null
Returns all the values of the specified request header as an array of String objects.
Some headers, such as Accept-Language can be sent by clients as several headers each with a different value rather than sending the header as a comma separated list.
If the request did not include any headers of the specified name, this method returns an empty array. The header name is case insensitive. You can use this method with any request header.
Parameters
String name a String specifying the header name
Returns: Array an array containing the values of the requested header. If the request does not have any headers of that name return an empty enumeration. If the container does not allow access to header information, return null
Returns the value of the specified request header as an int. If the request does not have a header of the specified name, this method returns -1. If the header cannot be converted to an integer, this method throws a NumberFormatException.
The header name is case insensitive.
Parameters
String name a String specifying the name of a request header
Returns: Number an integer expressing the value of the request header or -1 if the request doesn't have a header of this name
Returns the Internet Protocol (IP) address of the interface on which the request was received.

Returns the Internet Protocol (IP) port number of the interface on which the request was received.
Returns: Number an integer specifying the port number
Returns the preferred Locale that the client will accept content in, based on the Accept-Language header. If the client request doesn't provide an Accept-Language header, this method returns the default locale for the server. Returns a well-formed IETF BCP 47 language tag representing this locale.
Returns: String the preferred Locale for the client
Returns an array of Locale objects indicating, in decreasing order starting with the preferred locale, the locales that are acceptable to the client based on the Accept-Language header. If the client request doesn't provide an Accept-Language header, this method returns an array containing one Locale, the default locale for the server. Returns well-formed IETF BCP 47 language tags representing the locales.
Returns: Array an array of preferred Locale objects for the client
Returns the name of the HTTP method with which this request was made, for example, GET, POST, or PUT. Same as the value of the CGI variable REQUEST_METHOD.
Returns: String a String specifying the name of the method with which this request was made
Returns the value of a request parameter as a String, or null if the parameter does not exist. Request parameters are extra information sent with the request. For HTTP servlets, parameters are contained in the query string or posted form data.
You should only use this method when you are sure the parameter has only one value. If the parameter might have more than one value, use #getParameterValues(String).
If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned by getParameterValues.
If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via #getInputStream or #getReader can interfere with the execution of this method.
Parameters
String name a String specifying the name of the parameter
Returns: String a String representing the single value of the parameter
Returns an object of the parameters of this request.
Request parameters are extra information sent with the request. For HTTP servlets, parameters are contained in the query string or posted form data.
Returns: Object an object containing parameter names as keys and parameter values as map values. The keys in the parameter map are of type String. The values in the parameter map are of type String array.
Returns an array of String objects containing the names of the parameters contained in this request. If the request has no parameters, the method returns an empty array.
Returns: Array an array of String objects, each String containing the name of a request parameter; or an empty array if the request has no parameters
Returns an array of String objects containing all of the values the given request parameter has, or null if the parameter does not exist.
If the parameter has a single value, the array has a length of 1.
Parameters
String name a String containing the name of the parameter whose value is requested
Returns: Array an array of String objects containing the parameter's values
Returns any extra path information associated with the URL the client sent when it made this request. The extra path information follows the servlet path but precedes the query string and will start with a "/" character.
This method returns null if there was no extra path information.
Same as the value of the CGI variable PATH_INFO.
Returns: String a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information
Returns any extra path information after the servlet name but before the query string, and translates it to a real path. Same as the value of the CGI variable PATH_TRANSLATED.
If the URL does not have any extra path information, this method returns null or the servlet container cannot translate the virtual path to a real path for any reason (such as when the web application is executed from an archive). The web container does not decode this string.
Returns: String a String specifying the real path, or null if the URL does not have any extra path information
Returns the name and version of the protocol the request uses in the form protocol/majorVersion.minorVersion, for example, HTTP/1.1. For HTTP servlets, the value returned is the same as the value of the CGI variable SERVER_PROTOCOL.
Returns: String a String containing the protocol name and version number
Returns the query string that is contained in the request URL after the path. This method returns null if the URL does not have a query string. Same as the value of the CGI variable QUERY_STRING.

Returns: String a String containing the IP address of the client that sent the request
Returns the fully qualified name of the client or the last proxy that sent the request. If the engine cannot or chooses not to resolve the hostname (to improve performance), this method returns the dotted-string form of the IP address. For HTTP servlets, same as the value of the CGI variable REMOTE_HOST.
Returns: String a String containing the fully qualified name of the client
Returns the Internet Protocol (IP) source port of the client or last proxy that sent the request.
