Hi Brock,

It will be short for 4.2.11 (eventually 4.2.12): I don’t want to hold 4.2.11 
any longer.

As you have a workaround (removing xml jar from lib/endorsed), I would prefer 
to target 4.2.12 if you don’t mind.

JB

Hi,

Yes, 90% of the use cases don’t need java.xml in lib/endorsed.

Hi JB

I know you are quite busy so no need to apologize.

Just to make sure I understood you correctly, the 
org.apache.karaf.specs.java.xml-4.2.10.jar can be permanently removed from the 
/endorsed dir without any negative side effects, right?

Hi Brock,

Sorry for the very late answer.

The reason why javax.xml is in lib/endorsed folder is because core Karaf loads 
just the spec and let you install the impl.
Anyway, you can remove it from endorsed and install bundles, it works as well.
It’s basically what we plan to do by default as part of KARAF-6703.

Hi João

Thank you for looking into this issue. Its nice to know it no longer appears in 
karaf 4.3, but is there another way to resolve this in 4.2.10 without changing 
the code? More specifically, is there a reason why 
org.apache.karaf.specs.java.xml-4.2.10.jar resides in the /endorsed directory 
as opposed to being exposed by a bundle? The reason for me asking is because 
the bundle approach would allow me to choose which implementation my bundle 
would reference, while the current endorsed approach leaves me no choice.

Regards,

Brock

Hi Brock,

I tried your jar but it failed due to the layout of the jar (the MANIFEST was 
not the first entry in the jar or something like that). I created a bundle with 
our code and when I tried with karaf 4.3 it passed.
I then tried with 4.2.7 and I experienced the same NPE. Apparently the behavior 
when the errorHandler is set to null is different between implementations of 
the XML libs supplied in these two versions of karaf.
In your code setting the error handler to builder.setErrorHandler(new 
org.xml.sax.helpers.DefaultHandler()); seems to do the trick.

I noticed your manifest is importing a bunch of packages not required for the 
code in question.

hi, JB.

thank you for looking at this. The attached zip (rename its extension from .txt 
to .zip) contains both the bundle (rename its extension from .txt to .jar) and 
its feature file. the bundle should be placed in the /bundles dir, and you know 
what to do with the feature file =)
here are some points regarding the bundle:
1) the bundle executes automatically during Karaf startup to make it easier for 
you.
2) The bundle contains both the schema and the xml, so you dont have to really 
do anything to the bundle itself in order for it to just run
3) The bundle contains props.properties where you can specify external 
locations to both schema and xml file if you choose to do so for any reason. 
The provided files will be ignored in such case.
4) I have also provided the source .java alongside the binary just in case.

again, really appreciate you taking the time to look at it. thanks!!!

Re: Need some help with running the HTTP example in the code base

[Jean-Baptiste Onofre]

Just to be clear

1. Download Karaf 4.2.10
2. Then use Karaf 4.2.10 example like this:

feature:repo-add 
mv:org.apache.karaf.examples/karaf-rest-example-features/4.2.10/xml
feature:install http
feature:install karaf-rest-example-scr

Re: Need some help with running the HTTP example in the code base

Hi,

The LATEST example only run on Karaf 4.3.x.

I suggest to use at least Karaf 4.2.x and use the example corresponding to the 
Karaf version.

[Som Shankar Bhattacharyya]

Hello,

So I am trying to set up a http example on karaf using JaxRS.
While following the instructions I am running into certain issues that I am
not sure how to proceed with.


   1. I am using Karaf version *4.1.3*
   2. I do a *maven clean install* using the code in
   https://github.com/apache/karaf/tree/master/examples/karaf-rest-example
   3. I do a f*eature:repo-add
   mvn:org.apache.karaf.examples/karaf-rest-example-features/LATEST/xml*

*I get this error ,*

Error executing command: Unable to resolve root: missing requirement [root]
osgi.identity; osgi.identity=http; type=karaf.feature;

I am a newbie to Karaf and am having difficulty in understanding this
error. Do I need to install something else ?

Hi Oleg,

Can you please etc/org.ops4j.pax.logging.cfg with this:

log4j2.logger.featureservice.name = org.apache.karaf.features
log4j2.logger.featureservice.level = DEBUG

And send the karaf.log to me ?

Thanks,

I did’t change any logging levels. How do I set the features service logging to
