whole thing is 250 KB and that includes XML pull parser

that can be even smaller and probably XPP3 will be just 3 classes.

if you app does not need server side functionality you can try to remove from
soaprpc all server related classes (such as ServerSocketFactory etc.)

1.5MB/250KB it is 6x smaller but there should be SOAP toolkits even smaller

and after all you can just open HTTP connection and send pre-formatted strings that
represent SOAP messages and use small XML parser  (such as XPP2) to do parsing of
result XML messages (it is easier then general SOAP toolkit as you need only to
parse few expected types of result messages)

that should be possible but we no longer consider it high priority as PDAs are
getting now bigger and run better and faster JVMs  (see for example iPAQ with
SavaJe XE runs JDK 1.3 ...)

check list of SOAP implementations at
http://www.soapware.org/directory/4/implementations
and
http://www.soaplite.com/#TOOLKITS (seems to be related)

keep in mind that XSOAP is open source project done by graduate students. we love
to be able to do it but it is not the only thing that we work on ...

thanks,
