Re: SOAP Attachment from RPC Service Question

My quick answer is:
Soap 2.3.1 is rather old - never the less I am still using it.

I personally have speed issues under java 1.5 - so i would suggest 
starting with Java 1.4 - if you do use Java 1.5 I'd love to hear your 
experiences - I'd love to move to java 1.5.....

Under either SOAP 2.3.1 or 2.3.0 there was an option zip - 
SOAPContext.setGzip(boolean)

I know thats probably not much help - but maybe....

Please let me know how that works out for you?
