DFS 6.5SP1: Importing Content using SOAP attachment

ank1

Can someone please let me know how to implement SOAP attachments in custom DFS services?

Right now XSD for my custom service contains this for base 64 transfer

<xs:element name="b" type="xs:base64Binary" nillable="true" minOccurs="0"/>

This transfers the content using base64 encoding. Instead I need to transfer content using SOAP Attachments.

Please let me know what should I do in it's place for transferring content using SOAP Attachments?

MTOM uses SOAP attachments for content transferring, Base64 uses SOAP body.

Base64 is suitable to send small content (e.g. <5K bytes). For larger

content files, it is more optimal to use MTOM

Is it still suitable to use MTOM if the content size is very large, say 50MB?

thanks,

you can try UCF mode, which is implemented privately. For more info, pls refer to DFS dev guide.

Yes, you can transfer 100MB content using MTOM.

In one of my expriemental testing, I can transfer up to 150MB of content with MTOB. I believe you can go higher, but you probably need to increase the heapsize setting at the content server. For a 150MB transfer, the weblogic server consumes appx. 600MB of memory.

Great! MTOM (& Base64) is high memory consumption. For efficiency and low memory cost, UCF is much better.

I not sure If you will see this. Were you able to complete this requirement? I have a similar requirement and just wonder If you can share the code. Thanks
