1. Get the grisu WSDL (from ngportal.vpac.org/grisu-ws/services/grisu)
2. Create C header (no sample xml)
wsdl2h -c -x -o grisu_ws.h grisu.wsdl
(NB: was a complaint here about missing typemap.dat)
3. Create C stub functions (no sample xml, client side only)
soapcpp2 -C -L -c -x grisu_ws.h
===========================
soapStub.h -> prototypes extracted from the WSDL
soapClient.c -> actual code for calling these web services
NB: link against soapssl NOT soap ... or it will complain.
--------------------------------
GRISU Authentication
Requires adding info to the soap header.
The basic steps are:
1) rewrite the SOAP_ENV__Header struct (soapStub.h) to
contain fields for the information we want to send
2) then we add some calls to the serializer routine
soap_out_SOAP_ENV__Header() (soapC.c) to embed and tag
these fields with the appropriate namespace and element names
3) now the client can allocate and set a new soap header, fill out
the fields and then make soap calls and the new header containing
authentication info will be serialized and sent as well.
myproxy credentials
===================
NB - the -a is needed for retrieval to work. Not 100% sure, but
could be because the myproxy server doesnt recognize the
certificate of the remote host that tries to retireve a credential
NB - also need to do setenv GT_PROXY_MODE = "old" for grisu to work.
This is a legacy issue, that will hopefully be fixed soon
NB - on my ubuntu box at home - some complaints about
MYPROXY_SERVER_DN which I havent yet been able to fix
Uploading: (do before running GDIS)
myproxy-init -l <name> -a -s myproxy.arcs.org.au
Retrieving: (test - if works - GDIS' soap requests should work)
myproxy-logon -l <name> -s myproxy.arcs.org.au
=======================
Current - create a text string containing XML (below) that describes
the job we want run. Pass this as the JDL to grisu ws?
Sample jdl taken from.
