Dynamic DB instance change at runtime

[webashlar]

Hello,

I am using SmartGWT Pro 3.0.1.

In my application, I want to make administrator able to change the database instance (hostname, portname, userid, pwd) run time using the UI named as DatabaseSetup.

I have gone through many post and came to conclusion that i have to change the Config property names like, Config.getGlobal().put("sql.PostgreSQL.driver.serverName", "testserver");

When i write above line, on the Loadstartup servlet it works fine but as per my requirement i want to change the db instance after the UI had been loaded so i tried to fire "Config.getGlobal().put("sql.PostgreSQL.driver.serverName", "testserver");" from the server on the save button click of DatabaseSetup form.

And after this i had checked whether above line took effect or not via,
Config.getGlobal().asProperties()

I see that sql.PostgreSQL.driver.serverName propery been changed to "testserver", but when i am trying to access the application i see application is still accessing the old server only.

Can you please let me know what is getting wrong here?

Thanks.
