Convert QR Jar to OSGi Bundle

[apenhorwood]

I am trying to convert a simple jar to an OSGi bundle.

project: QR Code generator library
jar is find here: io.nayuki » qrcodegen » 1.8.0 - jar download | JarCasting

I am trying to use cfadmin buildBundle but it is crashing on the start of the process. I found this code:

GitHub - lucee/OSGi-Bundle-creation

But I can’t seem to make it work.

OS: Windows 11
Java Version: Java 21
Servlet Version: Jetty 10
Lucee Version: Lucee 6.2.1.122

Try just editing the jar’s manifest:

1. Install 7-zip if you don’t have it
2. Right-click the jar and choose “Open archive” from the 7-zip menu
3. Open the META-INF folder and select MANIFEST.MF
4. Press F4 or choose File > Edit
5. Add the following to the end of the manifest:

Bundle-SymbolicName: io.nayuki.qrcodegen
Bundle-Version: 1.8.0

6. Save and close the file, choosing to update the archive.

Yes I completed the process manually. Not sure why the cfadmin function doesn’t work.

firstly, i’d be updating to 6.2.2.91, as it has a lot of bug fixes since 6.2.1

and with 6.2, you don’t need to worry about OSGI bundles anymore

the lovely new approach with javasettings just works™

Interacting with Java Libraries in Lucee 6.2 - qrcode example

With Lucee 6.2, one of our main objectives was to simplify Java integration as much as possible. We focused on making it easier to load libraries and adapt existing Java code to work seamlessly in Lucee. To achieve this, we approached it with a simple challenge: pick a third-party Java library and try to use it in Lucee with the least amount of friction. If we encountered any hurdles, we adapted Lucee accordingly. In short, we learned a lot from real-world examples and worked to overcome any une…
