Dear list,
Sorry about that, my e-mail has been sent too soon by mistake (also
from an incorrect exp. address). I was planning to add further details.
So I'm running Debian Lenny. sessionInfo() gives:
R version 2.7.1 (2008-06-23)
i486-pc-linux-gnu
locale:
C
attached base packages:
[1] stats graphics grDevices utils datasets methods
base Package: SSOAP
Version: 0.5-0
Date: 2009/05/04
Package: XML
Version: 2.3-0
Date: 2009/03/04
Package: RCurl
Version: 0.97-3
Package: XMLSchema
Version: 0.1-0
I must be stupid but I can't find XMLSchema on the omegahat website.
(I just installed the 0.1-0 version a few days ago when trying to use
SSOAP.) Google gives nothing useful for "XMLSchema site:omegahat.org".
http://www.omegahat.org/XMLSchema/XMLSchema_0.1-1.tar.gz
or from a link in
http://www.omegahat.org/XMLSchema/
or via the repository using
install.packages("XMLSchema", repos = "http://www.omegahat.org/R";)
Thanks a lot: with the new version, calling my SOAP services work like a
charm!
It would be nice to add a link to XMLSchema from the main page, to make
it easier to find for users... And for Google! (So that it will index
the page.)
Calling with the "normal" SOAP call works without trouble. However I
can't use the "genSOAPClientInterface" way... See example hereunder.

I can use the "normal" interface to my SOAP service anyway, so it is not
*that* important if I can't make the genSOAPClientInterface call work. I
just wanted to let you know, and also that way might reveal simpler for
my user... Please tell me if I can try something else, if you have some
time to look at it...

I'm beginner in both web services and R programming (my knowledge is
more in desktop & CORBA Java programming). I am simply trying to make
Java and R communicate (call Java code from R remotely), for use by
someone else who works in R. I'd like to provide him with a fully
functional example. I must recognize that having to step through
SSOAP code to find where the problem lies might be too difficult
considering my current knowledge (knowing I don't intend to become an
expert R programmer). Please don't take it as rude or implying that
I'm simply expecting someone to solve the problem for me: I am ready
to investigate but I'd simply like to have an idea of how difficult
it will be. If I have to patch part of SSOAP or if you think that the
functions I need are not implemented yet, then I'd better not insist
and try to communicate from R to Java using an other way. If on the
other hand you think it should be working and is simply a matter of
using the right version of the right package, or using an other web
services platform on the Java side, or configuring something
differently, etc., then I'll happily dig into it.
Either of Simon Urbanek's rJava or Rserve packages are worth
investigating.
More generally, if someone has a suggestion on what to use to call
Java over TCP/IP from R, I'd be interested. I am currently
considering OSS as well as SSOAP. I'd prefer learning an approach
that I can reuse for other languages, so possibly a standard like
SOAP or CORBA would be best.
Thanks for any pointer.

I tried different "action" values, because I don't know what I
should put there. But I always get the same error.
Also, FYI, the following command produces the following output:
smg8Def <-
processWSDL("http://smg8.ulb.ac.be:8080/axis2/services/Version?wsdl";,
verbose=TRUE)
processing (sub) schema http://axisversion.sample
1 ) Exception
2 ) Exception
3 ) getVersionResponse
Warning message:
In
processWSDL("http://smg8.ulb.ac.be:8080/axis2/services/Version?wsdl";,

and then
I also tried a simpler service (WSDL manually created myself, but I
am not sure it is correct although it validates):
smg8EchoDef <-
processWSDL("http://smg8.ulb.ac.be:8080/axis2/services/EchoService?wsdl";,
verbose=TRUE)
processing (sub) schema http://smg8.ulb.ac.be/echoSvc/
1 ) TheString
