I thought that one of the advantages of mtom was to use xop which describes how to package binary data as an attachment. @mr_d Well MTOM can be inlined or not. If you're dealing with small attachments, such as < 5k images or other binary data I don't see the problem if the MTOM attachments are inlined. If you're dealing with bigger attachments then I agree inlined MTOM attachmetns are not good for you. But it depends on the SOAP stack how it will deal with MTOM attachments. For example, some SOAP stacks are configured the following way: * if attachment size is lesser than some preconfigured size then MTOM attachment is inlined * if attachment size is greater than some preconfigured size then MTOM attachment is sent as MIME part. Isn't this your problem? Rio View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058006#...
