Disable recursive jar manifest 'Class-Path' verification [message #1758820] Mon, 03 April 2017 13:56 Go to next message

Hi

When I try to start VTS the engine tries to check if the elements of the 'Class-Path' entry exist. However one problem is that some jars have a wrong 'Class-Path' entry.

I have attached the following files:
- The 'error.txt' file shows the error I'm getting.
- The 'classpath_entry.txt' shows the 'MANIFEST.MF' of the jar that is causing the problem. In this case it's the 'msv-20050913'.
- The 'dependency_tree.txt' file is just to show that 'xfire-jaxb' depends on 'msv-20050913'.

I solved some of these issues by upgrading the dependencies but xfire is already in the latest version.

Is there a way to disable de 'Class-Path' verification?

Hi,

In your META-INF folder add/edit context.xml to contain the following:

<Context>
...
  <JarScanner scanManifest="false" />
...
</Context>


More information can be found here

Best Regards,
Violeta

Hi Emanuel,

It would be useful if you shared the version number of Virgo.
In any case, I don't think that it's possible to disable the verification. In my opinion that check is useful: what if you have an issue in your build scripts and a deployed bundle does not include a required JAR; would you be happy if Virgo did not report this?

I would suggest you to use BND or the Apache Felix Maven Bundle Plug-in [1] to repackage the offending bundle with correct OSGi metadata.
This is common in my company, we often find libraries that have wrong or missing OSGi metadata and we use the Apache Felix Maven Bundle Plug-in to repackage the libraries under a different group-id into our binary repository.

GianMaria.

The version I'm using is 3.7.0.RELEASE.

To me it seems the later solution by fixing the OSGI metadata is cleaner. It's still good to know how to disable such check.

Many thanks.

Hello

I have confirmed the repackaging solution works. In fact there are pre-made bundles in the maven repository:

https://mvnrepository.com/artifact/org.apache.servicemix.bundles

I'll try disabling 'class-path' verification next.

Thanks again

Disabling the manifest scan didn't work. Not sure why. The repackaging solution is good enough for me though.

To me the issue is closed.

Thanks
