    • getAttribute

      public Object getAttribute(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 programmatically 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. Names beginning with java.* and javax.* are reserved for use by the Servlet specification. Names beginning with sun.*, com.sun.*, oracle.* and com.oracle.*) are reserved for use by Oracle Corporation.

      Specified by:
      getAttribute in interface ServletRequest

      Return the names of all request attributes for this Request, or an empty Enumeration if there are none. Note that the attribute names returned will only be those for the attributes set via setAttribute(String, Object). Tomcat internal attributes will not be included although they are accessible via getAttribute(String). The Tomcat internal attributes include: The underlying connector may also expose request attributes. These all have names starting with "org.apache.tomcat" and include: Connector implementations may return some, all or none of these attributes and may also support additional attributes.

      public Locale getLocale()
      Description copied from interface: javax.servlet.ServletRequest
      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.
      Specified by:
      getLocale in interface ServletRequest
      Returns:
      the preferred Locale that the client will accept content in, based on the value for the first Accept-Language header that was encountered. If the request did not specify a preferred language, the server's default Locale is returned.

      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:
      getParameter in interface ServletRequest
      Parameters:
      name - Name of the desired request parameter
      Returns:
      the value of the specified request parameter, if any; otherwise, return null. If there is more than one value defined, return only the first one.

      Parameters:
      name - Name of the desired request parameter

    • getRequestDispatcher

      public RequestDispatcher getRequestDispatcher(String path)
      Description copied from interface: javax.servlet.ServletRequest
      Returns a RequestDispatcher object that acts as a wrapper for the resource located at the given path. A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.

      The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns null if the servlet container cannot return a RequestDispatcher.

      The difference between this method and ServletContext.getRequestDispatcher(java.lang.String) is that this method can take a relative path.

      Specified by:
      getRequestDispatcher in interface ServletRequest
      Parameters:
      path - Path of the resource to be wrapped
      Returns:
