Hello, I'm new doing "bundling", converting JARs to OSGi bundles.
I use Declarative Services.
I've convert a JAR file to an OSGi bundle (A), and I've got another bundle (B) that depends on it.

The problem I get is that the first bundle (A) needs to be read from a non executable text file in the other bundle (B).
I have tried to achieve it by configuration (MANIFEST.MF). I mean, there's an option to specify in Binary Build and Source Build the files that are going to be added to the binary or source build. But I get the same error from the "A" bundle (file not found exception). So I don't know if there's another way to configure non executable file's path.

I'd appreciate all your ideas, because I cannot find a suitable answer.

Thank you Very Happy

What do you mean by the first bundle (A) needs to be read from a non executable text file in the other bundle (B)? Is that some kind of script? How does it read the file in a non-OSGi environment?

The API on org.osgi.framework.Bundle such as Bundle.getEntry, Bundle.findEntries etc. can be used to locate resources in other bundles. But I am not sure that will help you if your non-executable file is not java code running as part of bundle B.

Tom.

Thank you Thomas for having answered my question

Sorry, I've been studying french for months and my English level...

The main idea is that bundleA is a library that generates and processes a state machine. So bundleB is a hardware controller that has a configuration file, a very simple text file, with a concrete state machine info. In that way, I can generate different hardware controllers using and changing this text file which will be loaded by bundleA.

But I don't know if I would have to convert all the code of the JAR. And made all changes by hand and avoid that "file loading" in that way. Maybe using factory components... don't know.
