    • getAttribute

      public Object getAttribute(String name)
      Description copied from interface: jakarta.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 jakarta.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 jakarta.* are reserved for use by the Jakarta EE platform.

      Specified by:
      getAttribute in interface ServletRequest
      Parameters:
      name - a String specifying the name of the attribute
      Returns:

      Returns:
      a long integer containing the length of the request body or -1 if the length is not known

    • getAttributeNames

      public Enumeration<String> getAttributeNames()
      Returns an Enumeration containing the names of the attributes available to this request. This method returns an empty Enumeration if the request has no attributes available to it.

      The attribute names returned will only be those for the attributes set via setAttribute(String, Object). Tomcat internal attributes will not be included even though 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.
      Specified by:

      Returns:
      an Enumeration of strings containing the names of the request's attributes

      Returns:
      an Enumeration of preferred Locale objects for the client

    • getParameter

      public String getParameter(String name)
      Description copied from interface: jakarta.servlet.ServletRequest

      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.

      Returns:
      A Map containing parameter names as keys and parameter values as map values.

    • getRequestDispatcher

      public RequestDispatcher getRequestDispatcher(String path)
      Description copied from interface: jakarta.servlet.ServletRequest

      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 - a String specifying the pathname to the resource. If it is relative, it must be relative against the current servlet.
      Returns:
      a RequestDispatcher object that acts as a wrapper for the resource at the specified path, or null if the servlet container cannot return a RequestDispatcher
