Let me describe a step-by-step guide so you can recreate it. Ok, I have constructed a small example using a freshly downloaded copy of Camel 2.4.0.
I'am using the provided example protobuffer definition from the example: addressbook.proto and run the protobuffer-compiler protoc to generate the Java-files After that created a spring-xml file in the META-INF/spring directory with the following content: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd";> <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";> <route> <from uri="direct:start"/> <unmarshal> <protobuf instanceClass="org.apache.camel.dataformat.protobuf.generated.AddressBookProtos$Person" /> </unmarshal> <to uri="mock:result"/> </route> </camelContext> </beans> Then created a small starter class which started the Camel-main class (org.apache.camel.spring.Main) and I get the following log with exceptions: 14-sep-2010 10:56:10 org.apache.camel.impl.MainSupport doStart INFO: Apache Camel 2.4.0 starting 14-sep-2010 10:56:10 org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.classpathxmlapplicationcont...@1457cb: startup date [Tue Sep 14 10:56:10 CEST 2010]; root of context hierarchy 14-sep-2010 10:56:10 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from file [D:\projects\CamelProtobufTest\bin\META-INF\spring\camel-protobuf-test.xml] 14-sep-2010 10:56:10 org.apache.camel.impl.MainSupport doStop INFO: Apache Camel 2.4.0 stopping org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 12 in XML document from file [D:\projects\CamelProtobufTest\bin\META-INF\spring\camel-protobuf-test.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'protobuf'.
