Binding components is another problem. Currently, servicemix-http and servicemix-jms are the only BC to fully handle attachments (input and output). SAAJ lw component can handle attachments when sending a request, email has no support for them yet, and I do not know if rss could even support it (an entry is just a string).
Just curious (I'm not a bpel expert at all), what kind of things can you do on attachments with bpel ? Do you use wsdl message parts to define them ? How can you create a non-xml attachment ?
