Bengt Rodehav commented on CAMEL-5798:
--------------------------------------
I attached a sample maven project with a simple, spring based, route that uses
xpath and saxon. I took the camel-example-osgi project and modified it a bit.
+On *ServiceMix 4.4.2* this works:+
* features:install camel-saxon
* install -s mvn:org.apache.camel/saxon-problem/2.10.2
+On *Karaf 2.3.0* this does NOT work:+
* features:install camel-saxon
* features:install camel-spring
* install -s mvn:org.apache.camel/saxon-problem/2.10.2
I get the following exception:

+On the other hand, on *Karaf 2.3.0* this does work:+
* features:install camel-core
* features:install camel-spring
* install -s
mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.xmlresolver/1.2_5
* install -s
mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.saxon/9.4.0.4_1
* install -s mvn:org.apache.camel/saxon-problem/2.10.2
This implies that the xmlresolver is needed and is in fact present by default
in ServiceMix 4.4.2.
+But, strangely enough, this does NOT work on *Karaf 2.3.0*:+
* features:install camel-core
* features:install camel-spring
* install -s
mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.xmlresolver/1.2_5
* install -s
mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.saxon/9.3.0.11_2
* install -s mvn:org.apache.camel/saxon-problem/2.10.2
I just changed the Saxon version from the latest to the one used in the
camel-saxon feature.
I'm not sure what this means. It seems like the xmlresolver is necessary but I
do not know why it only works with a newer Saxon. I also don't know what makes
it work under ServiceMix 4.4.2.

> Key: CAMEL-5798
> URL: https://issues.apache.org/jira/browse/CAMEL-5798
> Project: Camel
> Issue Type: Bug
> Components: camel-saxon
> Affects Versions: 2.10.2
> Reporter: Bengt Rodehav
> Attachments: saxon-problem.zip
>
>
> This has been discussed on the mailing list:
> http://camel.465427.n5.nabble.com/Saxon-and-saxon9he-td5722663.html
> It seems like the camel-saxon feature only has been tested on Servicemix and
> not on a pure Karaf installation. Servicemix comes with a pre-installed
> XmlResolver while Karaf doesn't and it seems like camel-saxon requires an
> XmlResolver. It should therefore be added to the camel-saxon feature.
