               throws java.io.IOException
```
    Send an error response.
    In addition to the servlet standard handling, this method supports some additional codes:
    
    102
    Send a partial PROCESSING response and allow additional responses
    
    -1
    Abort the HttpChannel and close the connection/stream
    
    Specified by:
    
    sendError in interface javax.servlet.http.HttpServletResponse
    
    Parameters:
    
    code - The error code
    
    message - The message
    
    Throws:
    
    java.io.IOException - If an IO problem occurred sending the error response.
  - sendProcessing
```
public void sendProcessing()
                    throws java.io.IOException
```
    Sends a 102-Processing response. If the connection is an HTTP connection, the version is 1.1 and the request has a Expect header starting with 102, then a 102 response is sent. This indicates that the request still be processed and real response can still be sent. This method is called by sendError if it is passed 102.
    
    Throws:
    
    java.io.IOException - if unable to send the 102 response
