We have vfp9 desktop application that's deployed for few years now for customer XYZ.
We lately built a Java web application running on Tomcat with Spring/Hibernate and Oracle 11g.

Now we have the user download one exe installation (built using wise) and kaboom installed, done.

The new web application running on our server, all is fine for those customers.

Our customer XYZ do not want to go web. they want to keep the app on their servers (100s). the user go to the field to do their work and come back sync their new work with the server.
Because of VFP end of life we want to install our web on their PC and servers. let say it is a large number of users (1000s)

Here is the question: how do you think I should change in the web app as described above to have one simple install for the user like we have now for VFP. We would like to re-use our web app for this customer but installing oracle (even xe) Tomcat and configuration would be a big mess. any idea??? any suggestion on new tools etc ???
