Hi everybody,
how can I send an attachment from the client to an server without
using the DataHandler in the method signature? I tried
to get the MessageContext (getCurrentMessageContext()), but it
returns null.

How can I obtain an messageContext to set the attachment to an
message in the client?

Thanks in advance,

Stefan



Hello,
I have an example where the server sends an attachment


public SOAPEnvelope extractReport(String _reportName, String _path, 
HashMap _parameters, String _format)
           throws RemoteException {
       trace.info("Extracting report...");

       try {
           MessageContext msgContext = MessageContext.getCurrentContext();
           Message response = msgContext.getResponseMessage();
           Iterator attachmentsIterator = response.getAttachments();

           if (attachmentsIterator == null) {
               trace.fatal("No Support for attachments !");
               throw new SOAPException("No Support for attachments");
           }
           //Crystal Reports Extraction
           ReportBuilder builder = ReportFactory.getFactory().getBuilder();
           ByteArrayOutputStream out = new ByteArrayOutputStream();
           ReportFormat format = ReportFormat.getReportFormat(_format);
           final String host = 
ConfigSingleton.getInstance().getConfiguration().getString(Conf.CRYSTAL_HOST);
           Exportable export = new ExportableImpl(out, format, host, 
_parameters, _path);
           builder.getReport(export).export();
           ByteArrayInputStream input = new 
ByteArrayInputStream(out.toByteArray());
           AttachmentPart current = response.createAttachmentPart();
           current.setContent(input, format.getContentType());
           
current.setContentId(_reportName!=null?_reportName:REPORT_CONTENT_ID);
           response.addAttachmentPart(current);
           response.saveChanges();
           return response.getSOAPEnvelope();
       } catch (ReportException e) {
           trace.error(getClass().getName() + ".extractReport():" + 
e.getMessage(), e);
           throw new RemoteException(e.getMessage(), e);
       } catch (SOAPException e) {
           trace.error(getClass().getName() + ".extractReport():" + 
e.getMessage(), e);
           throw new RemoteException(e.getMessage(), e);
       } catch (ConfigurationException e) {
           trace.error(getClass().getName() + ".extractReport():" + 
e.getMessage(), e);
           throw new RemoteException(e.getMessage(), e);
       } finally {
           trace.info("Report extracted");
       }
   }


Hope this helps
