Hi Julian, What example did you try? I've never used Jira before, is it free to use? To start I could show you the blueprint I am trying to deploy in my karaf container:
<?xml version="1.0" encoding="UTF-8"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"; xsi:schemaLocation=" http://www.osgi.org/xmlns/blueprint/v1.0.0 https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0 http://aries.apache.org/schemas/blueprint-cm/blueprint-cm-1.1.0.xsd";> <camelContext id="PLC-Context" xmlns="http://camel.apache.org/schema/blueprint"; streamCache="true"> <route id="Route1"> <from uri="plc4x:s7:localhost/1/1"/> <to uri="mock:test"/> </route> </camelContext> </blueprint> It is very simple but I am for now just trying to establish the connection to the PLC via blueprint. What's strange here for me is that I tried your example on git (PLC4X+Karaf) and it worked with the same bundle installed and running (the S7 driver is found). That's why I don't really understand the error I am getting (Unable to find driver for protocol 's7'). Hope my explanation are not too confusing, I am starting my second week only of my internship and it's my first time working with OSGi and blueprints ;-) Etienne On 2020/02/16 19:14:04, Julian Feinauer <[email protected]> wrote: > Hi Etienne, > > sorry for the delay, I was a bit ill the last days. > I will indeed have a closer look on your use case. > I never used Camel in OSGi except for one ver simple blueprint test, so it > could take me some time. > > Would you mind opening a Jira issue for that? > Then I can comment there and hopefully bring in a bit of analysis. > > Thanks! > Julian > > Am 14.02.20, 23:34 schrieb "Etienne Robinet" <[email protected]>: > > Hello everyone, > I've spent some days trying to figure out how to make PLC4X work inside a > karaf container in combination with camel blueprints for routing. > I've downloaded the latest release (0.5.0) and built it with maven.
