[gme-users] exception loading UdmCopy based XML backend

[Ray, Sumit (US SSA)]

Hi,

I am getting the following exception loading an XML backend file built using udmcopy:
"exception: Couldn't find in cache the class of element 'RootFolder'

Here's the snippet of code that causes it:
int main(int argc, char** argv)
{
  try
  {
    Udm::SmartDataNetwork nw(Uml::diagram);
    nw.OpenExisting("tm.xml");
...



The tm.xml is the diagram file based on the meta "test.xml", created using the command "udmcopy tm.mga tm.xml test.xml". If I replace the diagram xml with the meta xml, it seems to work fine. Any suggestions?

Thanks,
Sumit

Sumit,

The chief advantage with UDM is that you can use the XML backend to write
standalone interpreters that are completely independent of GME.  The Udm
installation comes with a utility called UdmCopy that can convert a GME
model into the equivalent XML digestable by Udm.  Your interpreter will
need to include the Udm-generated code, and either include the generated
xsd file in your distribution or else compile it into the code (see the Udm
command-line options).  Instead of all of the COM infrastructure that you
used to integrate your interpreter code into GME, you can simply write a
main function that loads the specified model file and invokes your logic.
 The only tricks are to link against the UDM library, and to make sure you
commit model changes before closing.  UdmCopy and Udm should both provide
command-line help when run from the prompt.

Is that what you're after?

-Joe
