Hello,
looking at the specification from XML-RPC it should be no problem to use
xml-rpc within QT. But how can I login into OME. I  took a look at the
ALLIGATOR tool.
Alligator send the following post to login:
<?xml version="1.0" encoding="ISO-8859-1"?>
<methodCall>
      <methodName>createSession</methodName>
      <params>
        <param><value>user</value></param>
        <param><value>omeuser</value></param>
      </params>
</methodCall>

I tried to post the same. As result I got the following:

<?xml version="1.0"
encoding="UTF-8"?><methodResponse><fault><value><struct><member><name>faultString</name><value><string>Cannot
create session at
/usr/lib/perl5/site_perl/5.8.6/OME/Remote/Dispatcher.pm line 172.
</string></value></member><member><name>faultCode</name><value><int>102</int></value></member></struct></value></fault></methodResponse>

So is there a way how I can login into the system.

Thanks very much gerhard
