Failed to load type converters

[ambarish.d]

I created a Camel based JMS Utility jar which will be embeded inside WAR file of Tomcat web project.
My corporate infrastructure uses IBM MQ and ActiveMQ and both supporting jars are in Tomcat/lib and there is strict policy that application should not use these Jars within there app/lib.

Now, I am adding my utility jars and camel jars (mentioned the list below) in app/lib but I am getting : "org.apache.camel.TypeConverterLoaderException: Failed to load type converters because of: Cannot find any type converter classes from the following packages: [org.apache.activemq.camel.converter]"

I have included following Jars:

camel-core-2.9.0.jar
camel-jms-2.9.0.jar
slf4j and spring jars.

Any help will be really appriciated. thanks in advance.
Below is the Exception snapshot:

Hi

your question has been answered here:

Babak,

Thanks but I am already using camel 2.9.0.
For ActiveMQ I am on 5.4.2 and out of scope for me to upgrade provider version.

Is there any workaround available for this issue.

[Babak Vahdat]

The problem is the AMQ version you make use of, that's the content of this file:

https://svn.apache.org/repos/asf/activemq/tags/activemq-5.4.2/activemq-camel/src/main/resources/META-INF/services/org/apache/camel/TypeConverter

Which in 5.6.0 makes use of FQN:

https://svn.apache.org/repos/asf/activemq/tags/activemq-5.6.0/activemq-camel/src/main/resources/META-INF/services/org/apache/camel/TypeConverter

I'm not aware of any other workaround other than upgrading to AMQ 5.6.0. However others in the forum may know about other possible options.

Hi

Yes you need to use AMQ 5.6.0 which is compatible with Camel 2.9.x onwards.

If using older AMQ releases you would need to patch the JAR yourself,
eg as Babak has shown below, its fairly simple as you would need to
patch the TypeConverter file in the META-INF dir.

Another alternative is to downgrade Camel. I think either you would
have to go down to 2.8 or 2.7 releases, which was not as strict in
case of failed type converter loading during startup.
