Jar file: load configuration files in jar

Question

I exported a project that reads 2 configuration files. However, when I execute the jar, it gets this error:

    Error: java.io.FileNotFoundException: config/dbConnection.config (No such file or directory)
    Error: java.io.FileNotFoundException: config/test.config (No such file or directory)
    com.smart.ets.services.ServiceException: com.smart.ets.services.ConfigErrorException

Any way to fix this? It works if I run the project(not the jar file of the project)

Answer 1

You neglect to mention how you're accessing the files, but from the error it looks like you're trying to access them as files--but they're not, they're resources on the classpath.

As such, you should be using getResourceAsStream . The name of the resource would be the package-relative path.
