Access to MSSQLserver via CamelRoute in ServiceMix

Question

I have an existing route in Camel with a jdbc endpoint which connects to a mssql server. That works fine.

Now i want to switch to apache servicemix to use that 'hot blueprint deployment'-feature.

The download i used: http://www.apache.org/dyn/closer.lua/servicemix/servicemix-6/6.1.0/apache-servicemix-6.1.0.zip.

The installations i did after startup of servicemix.bat:

karaf@root>feature:install camel-jetty
karaf@root>feature:install spring-jdbc
karaf@root>feature:install jdbc
karaf@root>feature:install webconsole

I want to use the jtds driver, so i also did:

karaf@root>install -s wrap:mvn:net.sourceforge.jtds/jtds/1.3.1

hoping this is correct...

Here is the blueprint-xml i copied to the deploy folder:

<?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"
    xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 
    http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">

    <bean id="myDataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
            <property name="driverClass" value="net.sourceforge.jtds.jdbc.Driver"/>
            <property name="url" value="jdbc:jtds:sqlserver://theserver:1433/thedbname;user=theuser;password=thepass"/>
        </bean>

        <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route id="db">
            <from uri="file://c:/tmp/camel/in"/>
            <setBody>
                <simple>select count(*) from io</simple>
            </setBody>
            <to uri="jdbc:myDataSource" />
            <to uri="file://c:/tmp/camel/out"/>
          </route>

        </camelContext>
    </blueprint>

As you see for the moment i just want to count the rows in a table named 'io' when a file arrives in a folder. The result should be written to another folder.

And here the content of the logfile after the copy:

I think the reason is here:

Bundle mytest/1.0.0 is waiting for dependencies [(&(component=jdbc)(objectClass=org.apache.camel.spi.ComponentResolver))]

So the questions are:

What does that mean?
and how to fix that issue?

Thx for your time.

You need to install camel-jdbc as you use jdbc in your Camel route

karaf@root>feature:install camel-jdbc

And since you just copy a blueprint xml to the deploy folder, you may need to add dynamic import on its bundle id, so do a

osgi:list

And find the bundle id in the list, and then

dev:dynamic-import <ID>

And then restart it

osgi:restart <ID>

The latter can be needed to allow your blueprint xml file to load the jdbc driver.

`feature:install camel-jdbc` did it, thx. `osgi:list` does not work but `list` does. The same for `dev:dynamic-import`, `dynamic-import` works. Also the restart was not needed in my environment. Nevertheless - it works now. thx again. – chris Dec 08 '15 at 06:48
yeah the karaf commands changed in the newer versions, so i think its bundle instead of osgi etc. If there is no name clash you can run the command without its prefix, and hence why they may appear to work – Claus Ibsen Dec 08 '15 at 07:33
