In that case, you cannot use the OLE/COM approach, sorry. To use OLE you must have \
the application installed on a computer - ideally on a stand alone PC - so that you \
can instantiate it and then manipulate that instance. If you had that available, then \
yes, you certainly could create and manipulate diagrams.

Looks like you are back to searching for an API that will create Visio files for you \
or a commercial product that does the same, or you could help Nick and the team \
develop that strand of POI further.

Hi,

When you say you can manipulate Visio using Java code, you mean creatting
Visio .vsd file using java ? and the other thing that I want to understand
is running Visio in the server side ? what exactly does this mean..

I will explain the requirement more clearly, I want to generate a Visio vsd
or vdx file without a visio installation. Note that I want this to be an API
and not a standalone GUI. I want this to work both for Windows and Linux
Operations systems. The visio generation should take inputs from my
application. I'm also open to take a look at commercial APIs.

Thanks again for your responses.

Regards,
Ashok.
