Problem with ObjectInputStream and WebRequest.setUserData & .getUserData()

[Alvin Antony <Al...@consol.de>]

Dear Friends,
 
I am new to the mailing list and so to Cactus!! Please pardon me if it
is a silly Q.
 
I am writing a test suit for an Applet& Servlet client server
Application. 
The Applet sends the information to the Servlet through an Object
stream, but my test case for this throws an EOFException.
 
 
public void beginService ( WebRequest webRequest ) throws
ClassNotFoundException, IOException 
    {          
        ProdFinderIntegratonTestRepository prodFinderIntegrationTestRep
= new ProdFinderIntegratonTestRepository ();
        Map input;
        try {
            input =
prodFinderIntegrationTestRep.getRequestToCreateMainCategory();
                    assertNotNull( input );
                    
                    ByteArrayOutputStream bos = new
ByteArrayOutputStream();        
                    ObjectOutputStream oos = new ObjectOutputStream( bos
);
                    oos.writeObject( input );
                    oos.flush();     
                    bos.close();
                    ByteArrayInputStream byteArrayInputStream  =  new
ByteArrayInputStream( bos.toByteArray() );        
                    objectInputStream = new ObjectInputStream(
byteArrayInputStream );        
                    webRequest.setContentType("application/binary");
                    webRequest.setUserData( objectInputStream ) ;       
        } catch (ObjectNotFoundException e) {            
            e.printStackTrace();
        } catch (PFInternalError e) {           
            e.printStackTrace();
        
        } 
    }
 
    /**
     * 
     * Class under test for void service(HttpServletRequest,
HttpServletResponse)
     */
    public void testService() throws ServletException, IOException {

        InputStream is =  request.getInputStream();        
        ObjectInputStream oInput = new ObjectInputStream(is);        
        MessageReceiver messageReceiver = new MessageReceiver();
        messageReceiver.init( config );
        messageReceiver.service(request, response );
        assertNotNull( response);        
    }

Any help would be great
 
Thanks in advance,

RE: Problem with ObjectInputStream and WebRequest.setUserData & .getUserData()

[Vincent Massol <vm...@pivolis.com>]

Hi Alvin,

Personally I've never tried reading data with an ObjectInputStream inside
Cactus. The test we have for the setuserData() feature is the following:

    public void beginSendUserData(WebRequest theRequest)
    {
        ByteArrayInputStream bais = new ByteArrayInputStream(
            "<data>some data to send in the body</data>".getBytes());

        theRequest.setUserData(bais);
        theRequest.setContentType("text/xml");
    }

    /**
     * Verify that we can send arbitrary data in the request body.
     * 
     * @exception Exception on test failure
     */
    public void testSendUserData() throws Exception
    {
        String buffer;
        StringBuffer body = new StringBuffer();

        BufferedReader reader = request.getReader();

        while ((buffer = reader.readLine()) != null)
        {
            body.append(buffer);
        }

        assertEquals("<data>some data to send in the body</data>", 
            body.toString());
        assertEquals("text/xml", request.getContentType());
    }

Hmm... Maybe the problem is with the "request.getInputStream();". In the
test above it's doing a "request.getReader()".

It would be nice to have another test with an input stream to try to
reproduce your problem. If you could come up with a simple test as above
that would reproduce the problem, I could add it to the Cactus test suite
and we could tackle the problem (if any) and fix it.

Thanks
