getAttribute

public java.lang.Object getAttribute(java.lang.String name)

Description copied from interface: javax.servlet.ServletRequest

Returns the value of the named attribute as an Object, or null if no attribute of the given name exists.

Attributes can be set two ways. The servlet container may set attributes to make available custom information about a request. For example, for requests made using HTTPS, the attribute javax.servlet.request.X509Certificate can be used to retrieve information on the certificate of the client. Attributes can also be set programatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.

Attribute names should follow the same conventions as package names. This specification reserves names matching java.*, javax.*, and sun.*.

Specified by:

getAttribute in interface javax.servlet.ServletRequest

Parameters:

name - a String specifying the name of the attribute

Returns:

an Object containing the value of the attribute, or null if the attribute does not exist

getParameter

public java.lang.String getParameter(java.lang.String name)

Description copied from interface: javax.servlet.ServletRequest

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 ServletRequest.getParameterValues(java.lang.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 ServletRequest.getInputStream() or ServletRequest.getReader() can interfere with the execution of this method.

Specified by:

Attribute names should follow the same conventions as package names. Names beginning with java.*, javax.*, and com.sun.*, are reserved for use by Sun Microsystems.
If the object passed in is null, the effect is the same as calling ServletRequest.removeAttribute(java.lang.String).
It is warned that when the request is dispatched from the servlet resides in a different web application by RequestDispatcher, the object set by this method may not be correctly retrieved in the caller servlet.

Specified by:

setAttribute in interface javax.servlet.ServletRequest

Parameters:

name - a String specifying the name of the attribute

o - the Object to be stored

removeAttribute

Specified by:

removeAttribute in interface javax.servlet.ServletRequest

Parameters:

name - a String specifying the name of the attribute to remove
