InputStream.getResourceAsStream() giving null pointer exception

Question

The line persistenceProperties.load(is); is throwing a nullpointerexception in the following method. How can I resolve this error?

Answer 1

Your IDE works with two different scopes:

• production scope: src/main/java + src/main/resources folders and
• test scope: src/test/java + src/test/resources

Seems you are trying to execute you program from production scope, while persistence.properties file is placed into test scope.

How to fix:

• Place your test into src/test/java or
• Move persistence.properties into src/main/resources
