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

    Caused by: com.smart.ets.services.ConfigErrorException
        ... 3 more

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

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.
