I have a server running many users and all of them have installed Smart Client via desktop shortcut. Server is version 4.1.7 i1-build 691. Solution is loaded via the URL: http://server/servoy-client/solution.jnlp . Many times after restarting the server and importing the latest version of the solution, the clients desktop shortcut no longer works and they are required to reinstall the application. This gets very tedious as some users have to do this several times a month. Problem mostly affects Windows users. Is they any know reason or fix for this? Seems to happen more often when I make schema changes. For example, I login to MySQL Admin and change the size of a VARCHAR text column from 25 up to 50, then restart the server, then import the solution.
Check your version of the JRE installed on the client. Versions 1.6.0_6 through 1.6.0_20 all had a problem with the pointer to the cache not being updated properly after the server updates the smart client. I experienced the same problem which disappeared after I updated the clients to version 1.6.0_21. There is a bug report on the JAVA site regarding this. Search for JAVA corrupted cache. Hope this helps.
