Wierd exception in JAXB deserialization

[Avinash Lakshman-3]

Could someone please give me some pointers as to where I should start looking when I attempt tracking this one?

We are reading some bytes from a TCP socket and submitting these bytes to be deserialized on a separate thread in a dedicated thread pool. Every once in a while I see this wierd exception.

Here is how I implement the serialization/deserialization:

public byte[] serialize(Object message) throws IOException
    { 
        byte[] bytes = new byte[0];
        long startTime = System.currentTimeMillis();
       
        if ( message != null )
        {
            try
            { 
                JAXBContext context =  SerializationManager.getContext();                      
                Marshaller m = context.createMarshaller();                
                FastByteArrayOutputStream bos = new FastByteArrayOutputStream();
                StAXDocumentSerializer sw = new StAXDocumentSerializer();
                sw.setOutputStream(bos);
                m.marshal(message, (XMLStreamWriter)sw);               
                bytes = bos.toByteArray();               
            }
            catch ( JAXBException ex )
            {
                SerializationManager.handleJAXBException(ex, message);           
            }
        }
        logger_.info("JAXB serialize: " + (System.currentTimeMillis() - startTime) + " ms.");
        return bytes;
    }

    public Object deserialize(byte[] bytes) throws IOException
    {
        Object message = null;       
        long startTime = System.currentTimeMillis();
        try
        {              
            JAXBContext context = SerializationManager.getContext();                        
            Unmarshaller um = context.createUnmarshaller();            
            FastByteArrayInputStream bis = new FastByteArrayInputStream(bytes);
            XMLStreamReader xr = new StAXDocumentParser(bis);           
            message = um.unmarshal(xr);           
        }
        catch ( JAXBException ex )
        {           
            SerializationManager.handleJAXBException(ex);           
        }
        logger_.info("JAXB deserialize: " + (System.currentTimeMillis() - startTime) + " ms.");
        return message;
    }

What would cause this? Please advice.

Thanks

Hello,

can you pls. attach byte[] dump, result of serialize method call?

Thanks.

WBR,

Alexey.

Hi;

 

I use below code snip to convert a JAXB bean to a FI string in my application. I wonder if SAXDocumentSerializer support CDATA. If it supports, can you provide an example?

 

 

          ByteArrayOutputStream output = new ByteArrayOutputStream();

               SAXResult _result = new SAXResult();

                    SAXDocumentSerializer serializer = new SAXDocumentSerializer();

                    serializer.setOutputStream(output);

                    _result.setHandler(serializer);

                         _result.setLexicalHandler(serializer);

                    m.marshal(newPayload, _result);

 

 

 

Thanks

 

Quansheng Jia

Hello Quansheng Jia,

I wonder if SAXDocumentSerializer support CDATA.

There is CDATA processing code in SAXDocumentSerializer, so I expect it should work.

If it supports, can you provide an example?

Just wanted to make sure.

Using code snippet bellow, you got some error when processing CDATA?

Thanks.

WBR,

Alexey.

 

 

          ByteArrayOutputStream output = new ByteArrayOutputStream();

               SAXResult _result = new SAXResult();

                    SAXDocumentSerializer serializer = new SAXDocumentSerializer();

                    serializer.setOutputStream(output);

                    _result.setHandler(serializer);

                         _result.setLexicalHandler(serializer);

                    m.marshal(newPayload, _result);

 

 

 

Thanks

 

Quansheng Jia
