Subject Re: Move to Spring 3.0
Date Thu, 08 Apr 2010 08:50:26 GMT
I'm using camel 2.2.0 with spring 3.0.0 without any problems here.
Here is the relevant spring config:


    <!-- Change trace to true for debugging purposes -->
    <camel:camelContext id="jamesCamelContext" trace="false" >
        <camel:jmxAgent id="agent" disabled="true"/>
        <camel:template id="producerTemplate"/>
        <camel:routeBuilder ref="processorRoute" />
    </camel:camelContext>

In my pom.xml I use this:

  <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-core</artifactId>
      <version>2.2.0</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-spring</artifactId>
      <version>2.2.0</version>
      <scope>runtime</scope>
      <exclusions>
        <exclusion>
          <groupId>org.springframework</groupId>
          <artifactId>spring-web</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

As you see I exclude spring-web. Maybe you don't exclude it and so it
pull a "old" spring version and so something get mixed..

Bye,
Norman
