Hey,
I am trying to use the Java DSL and a properties file using the PropertiesComponent. I have created a UnitTest which works if I use Strings for the directories instead of Properties.
If I want to use properties, a Nullpointer occurs in the setup() method. The context is null there! The location is set correctly in the overridden method "createCamelContext". The file exists as in your source code example in /src/test/resources/firstTest-test.properties and has this content:
file.inbox=target/inbox
file.outbox=target/outbox
So, everything should be fine. But I cannot find out why it does not work
Can you please give me a hint? Thank you.
Best regards,
Kai
