Problem running camel-example-cxf in the ESB

ddc Sep 20, 2011 5:25 PM

Hi,

I successfully did the steps to run the example outside the esb (mvn exec:java -PHttpToJms/CamelTransport/etc.). However, when preparing to run them in the esb, I got the exception below after hot deploying the jar file, and the spring app state changed to Failed.

camel-example-cxf (2.7.1.fuse-00-27)

I'm running the ESB from apache-servicemix-4.4.0-fuse-00-43. I'm running the example from apache-camel-2.7.1-fuse-00-27. The OS is windows 7.

Configuration changes from default

During the ESB installation, in the install guide, chapter 2, there is an optional step of removing the jbi container.

I removed jbi-* & servicemix-* from featuresBoot in etc/org.apache.karaf.features.cfg. I also added the woodstox feature as a workaround to a problem I encountered running the ESB /cxf/HelloWorld example.

The Exception

org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from URL bundle://154.0:0/META-INF/spring/CxfRouteCamelContext.xml; nested exception is org.springframework.beans.FatalBeanException: NamespaceHandler class for namespace http://activemq.apache.org/schema/core not found; nested exception is java.lang.ClassNotFoundException: org.apache.xbean.spring.context.v2.XBeanNamespaceHandler not found from bundle

Any ideas on what I need to do to get the example working in the ESB?

Did you have a chance to install the xmlbean-spring bundle like this ?
mvn:org.apache.xbean/xbean-spring/3.4.3

Thanks Willem. Installing that bundle fixed the problem. The camel-example-cxf examples now run in the ESB.

What should be changed in the example to avoid other people from encountering the same problem?

I'm pretty new to osgi, but from looking at the example's manifest, it seems like it's missing an xbean.spring entry in the import-package list.

The pom has the xbean-spring dependency. Why wasn't the corresponding package included in the import-package list?

I have created a ticket to track this issue
http://fusesource.com/issues/browse/ESB-1545

Ideally the xbean-spring bundle should be preinstalled as part of ActiveMQ in the ESB.

Hi,

We have activemq-spring feature, but this feature isn't installed by default, so currently you can install activemq-spring feature before running camel-example-cxf.

Next release should have activemq-spring feature as default installed.
