Camel Scripting how-to ?

[Francois Liot <fr...@liot.org>]

Hi,

Trying to avoid use of servicemix-scripting jbi, and taking example to camel
blueprint example,
I'm trying to do a camel-script > jython transformer component.

./pom.xml
./src/main/resources/OSGI-INF/blueprint/blueprint.xml
./src/main/resources/org/apache/servicemix/examples/camel/MyTransform.py

./pom.xml


./src/main/resources/OSGI-INF/blueprint/blueprint.xml


./src/main/resources/org/apache/servicemix/examples/camel/MyTransform.py


deploying this component to servicemix 4.4.2 I get :


I do obtain the very same even when I previously install additional features
from Karaf :


Thanks in advance for your support.

Yeah, you should also install
mvn:org.apache.servicemix.specs/org.apache.servicemix.specs.scripting-api-1.0/1.9.0
which already in camel-script feature.

You should use feature which include all necessary bundles for you.

Class javax.script.ScriptEngineFactory is distributed with JRE 6.
Don't you use JRE 6?

May I ask why don't you use 'feature:install camel-script'? :) It's
safer than 'bundles:install' as it guarantees to install complete set
of bundles.

Best regards.
