Hi Thilina, Thanks for your response. The server implementation is in Perl. I will try to post it. The idea behind this web service was to get back a text file as a response, when the service "getAnnotation" is invoked.
Will i be able to get back this text file at the client end using axis 2? Thanks a lot. ----- Original Message ---- From: Thilina Gunarathne <[EMAIL PROTECTED]> To: [email protected] Sent: Tuesday, September 25, 2007 3:18:46 PM Subject: Re: Unable to retrieve attachment using AXIS2 Hi, Will it be possible for you to post your service implementation code.. Are you using any data binding mechanism in the server side. Your WSDL does not seem to define any binary content.. Are you planning to use MTOM or plain Soap with Attachments. Have a look at the following articles.. http://ws.apache.org/axis2/1_2/mtom-guide.html http://wso2.org/library/1148 http://wso2.org/library/1675 thanks, Thilina On 9/25/07, s n <[EMAIL PROTECTED]> wrote: > > Hi All, > > I am a new AXIS 2 user.
