server.properties file advise needed

[ectar]

I want to package my classes into Jar file and supply product to different customers. But I face the problem that database information is in server.properties file and this file suppose to be together with classes, thus suppose to be jared as well. This is a bit ineffective and hard to maintain?

What would be recommended way of having my classes in Jar and server properties separately?

It doesn't need to be in a .jar, it needs to be in the classpath. Typically, you'd put it in WEB-INF/lib/classes.
