Reading properties file

Hi,

I am setting up very basic web application. the application consists of 2 small applications.

1: web app
2: common app

The db related things are being done in common-app (connection, queries, etc - direct JDBC). and this common app is being added to the web app through JAR integration (using eclipse 3.3 include project). I want to keep my database connection properties in .properties file in the common app and read it when the first time servlet is called. But i am unable to do it. it gives me error that file not found. How should i setup?

P.S:
I apologise if this is wrong section for this question.

did you put the properties file in the correct folder?? I think it should be in the WEB-INF\classes folder but your case seems different. You have an ejb module inside war module which I am not clear with what you are saying...

might be my explanation were not clear. let me try again

I have one project say tracker-web. which is simple SERVLET based web application. framework involved in it.

There is another project say tracker-common. Which has all the common classes (including db classes based on simple JDBC). Since this project is going to be include in 2-3 projects (tracker-web, tracker-command, tracker-reports etc). so i want to place the one JDBC PROPERTIES file in that common project. This common project will then in turn added to all above mentioend web projects as JAR file.

So i want to keep the properties file in the jar file and read it from there.

I don't prefer putting in web-inf folder. since i'll be having 3-4 projects and for each project i'll have to place 1 file in 3-4 places.
