Hello Ray! I build a small example and it works. If you like, I can send you my example Eclipse project.
{code:title=MyPredicate.java} public class MyPredicate implements Predicate { public boolean matches(Exchange exchange) { return true; } } {code} {code:title=MyBean} public class MyBean { public void process(Exchange exchange) throws Exception { System.out.println("received exchange: " + exchange); } } {code} {code:title=FilterSpringIntegrationTest} public class FilterSpringIntegrationTest extends CamelSpringTestSupport { @EndpointInject(uri = "direct:start") private ProducerTemplate template; @Test public void testFilterPredicate() { Object response = template.requestBody("Hello Camel"); System.out.println("received response: " + response); } @Override protected AbstractXmlApplicationContext createApplicationContext() { return new ClassPathXmlApplicationContext("META-INF/spring/bundle-context.xml"); } } {code} {code:title=bundle-context.xml} <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/spring" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> <camel:camelContext trace="true"> <camel:route> <camel:from uri="direct:start" /> <camel:filter> <camel:method ref="myPredicate" /> <camel:bean ref="myBean" method="process" /> </camel:filter> </camel:route> </camel:camelContext> <bean id="myPredicate" class="org.apache.camel.cmueller.MyPredicate"/> <bean id="myBean" class="org.apache.camel.cmueller.MyBean"/> </beans> {code} {code:title=pom.xml} <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.apache.camel.cmueller</groupId> <artifactId>filter-example</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-core</artifactId> <version>2.4.0</version> </dependency> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-test</artifactId> <version>2.4.0</version> <scope>test</scope> </dependency> </dependencies> </project> {code} Cheers, Christian
