Re: [Axis2][Rampart] Rampart and SwA
Hi Sebastian, thanks for the answer. I know that Rampart is able to secure MTOM messages. But utilizing MTOM is not usable for large messages. The amount of required memory is that high it is not usable for our project... There can't be any difference between the memory consumption of SwA & MTOM in Axis2, since they both are using the same logic underneath, unless you explicitly reads in the MTOM attachments to memory (by retrieving the actual binary). I don't know the excact reasons for that, but in our performance tests the MTOM approach requires a lot of additional memory. If your use case is securing the messages together with the binary attachments, then all the MTOM attachments might needs to be read in to the memory. It'll be the same if you are able to secure SwA type attachments.. A test case to figure this out would be very useful for us to fix this, if there is any such behaviour. The MTOM approach with file caching needs additional excecution time. Therefore we try to implement processing of large messages(more than 100MB) with SwA and java streams. Once again, the underlying layer is the same.. So theoretically they should take the same time.. Do you know where I can ask questions concerning the roadmap of specific components of Axis2?

Re: [Axis2][Rampart] Rampart and SwA
Also, some research I did indicated (if I understood it correctly) that in Axis1.1.1 MTOM doesn't really work as an attachment - it ALWAYS will get encoded as Base64 embedded in the message - there was a config option previously (in Axis1.0) that allowed some sort of parameter to define binary data nodes, but it seems to have disappears. AFAIK it is working as expected... Can you give us more specific clues... Please use TCPMON to capture messages.. SOAPMonitor has a bug which shows all the attachments as inline base64.. ~Thilina -Original Message- From: Sebastian Roschke [mailto:[EMAIL PROTECTED] Sent: Thursday, March 01, 2007 5:04 AM To: axis-user@ws.apache.org Subject: Re: [Axis2][Rampart] Rampart and SwA Hi Thilina, thanks for the answer.

RE: [Axis2][Rampart] Rampart and SwA
I have done some investigating in the Rampart module and one reason it uses a lot of memory is that in the RampartEngine it creates a RampartMessageData which appears to convert the entire message to a DOM and then back to OM. Bypassing this processing by modifying the Rampart module.xml allows us to do "true" streaming (but of course, you can't do that if you actually want Rampart to modify the outbound or inbound message). Also, some research I did indicated (if I understood it correctly) that in Axis1.1.1 MTOM doesn't really work as an attachment - it ALWAYS will get encoded as Base64 embedded in the message - there was a config option previously (in Axis1.0) that allowed some sort of parameter to define binary data nodes, but it seems to have disappears. -Original Message- From: Sebastian Roschke [mailto:[EMAIL PROTECTED] Sent: Thursday, March 01, 2007 5:04 AM To: axis-user@ws.apache.org Subject: Re: [Axis2][Rampart] Rampart and SwA Hi Thilina, thanks for the answer.

Re: [Axis2][Rampart] Rampart and SwA
Rampart has the capability to secure attachments send using MTOM.. I'm not sure whether is there or planned support for SwA..
