Hi Sean,

The code was:

                                          JsonCasSerializer jcs = new 
JsonCasSerializer();
                        jcs.setPrettyPrint(true); // do some configuration
                        StringWriter sw = new StringWriter();                   
       
                        jcs.serialize(jcas.getCas(), sw); // serialize into sw

and the error was:

Exception in thread "main" java.lang.NoSuchMethodError:

Hi Avanish,

I think that Apache email services do not allow markups, embedded images or 
attachments.  Your images didn't come through for me.  Can you paste the code 
as text?  If it is online somewhere public (e.g. github) you can add a link to 
the repository for people to inspect.

Thanks,
Sean
