Hi,
I am trying to get a Swing application running and connecting to an EOF
AppServer. I am trying to do it in a way that I have all and Swing only
UI control. No nibs, no rules, no XML, all written in Swing and a part
of the distributed desktop application.
The only lead Apple gives on this kind of applications is a two page
how-to that describes how to make a Swing project, add the client side
EOF jars, add an application URL property, and set the main class of
the app to:
com.webobjects.eoapplication.client.EOClientAppplicationSupport
This approach results in the app turning all the control to
EOClientApplicationSupport, which then establishes a distribution
channel, but also generates the UI and sends it back to the client. As
described, this is NOT what I try to achieve.
I was tampering with skipping the switching of the main class of the
app to EOClientApplicationSupport, and tried to establish a connection
in my own code (see below). Did manage to get a distribution channel
running, made a distributed object store and an editing context that
took it as it's parent, but when trying to fetch data I get the
exception (below) ON THE APPLICATION SERVER project (that is running in
the background so I could connect to from the Swing app).
ANY kind of help would be very welcome as the only documentation I can
find on the issue is EOF API reference. Is there a way to use EOF and
it's ClientApplicationSupport without giving all the control to the
standard JC handling?
