Unable to convert value from passed Service object

Hello All,

I have a bundle A that exports a javax.jms.connectionFactory service

Bundle B uses this service in blueprint to configure a JmsConfiguration
which in turn configures an ActiveMQComponent as shown below:

<reference id="pcf" interface="javax.jms.ConnectionFactory"
filter="(osgi.jndi.service.name=activemq/MyConnectPool)"/>

<bean id="jmsConfig"
class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="pcf"/>
<property name="concurrentConsumers" value="10"/>
</bean>

<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig"/>
</bean>

However, when I pass the JmsConfiguration to the ActiveMQComponent I get the
exception:

"Unable to convert value
***@258cd73e to type
org.apache.camel.component.jms.JmsConfiguration"

Now this is using ServiceMix 4.5.3; I have this working without this error
in another 4.5.3 environment; can anyone suggest why this is happening ?

Many thanks,
John.

Hi John,

That usually happens if you have multiple versions of the same bundle
installed in the container. Every bundle has its own classloader, so
you end up with multiple definitions for the same class. Could you
check for multiple versions of the camel-jms bundle as well as the
activemq bundles in your container? Something like "osgi:list -t 0 |
grep -i jms" and "osgi:list -t 0 | grep -i activemq" should do the
trick.

Regards,

Gert Vanthienen

Thanks for the reply Gert,

The server that I receive the error on returns the list below, and the
working server list is below that. Apart from the strange escape characters
in the second list the bundles and versions seem to be the same.

One thing I notice is that:
exports org.apache.activemq.camel.component

returns the activemq-camel and activemq-web-console bundles although this
is on both the working and non-working servers.

Is there any way to log the bundles class loaders to see what might be
getting loaded twice?

Server where I see the error:
