Move to Spring 3.0
Hi,
I am trying to shift my project(currently using Camel2.2.0 and Spring 2.5)
to spring 3.0. I have changed the spring version to 3 but I am getting the
following stack trace:
orCaused by: java.lang.NullPointerException
at org.apache.camel.impl.ProducerCache.<init>(ProducerCache.java:52)
at
org.apache.camel.impl.DefaultProducerTemplate.<init>(DefaultProducerTemplate.java:57)
at
org.apache.camel.spring.CamelProducerTemplateFactoryBean.getObject(CamelProducerTemplateFactoryBean.java:74)
at
org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:142)
After I debugged it I found something very strange in
CamelProducerTemplateFactoryBean. The getObject method is being called
before afterPropertiesSet method is called. That is why camel context is
uninitialized and hence the null pointer exception. I was wondering how this
could happen in Spring or am I missing some camel configuration for spring
3.0?

Re: Move to Spring 3.0
Posted by Norman Maurer <no...@googlemail.com>.
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

Can you create a JIRA with a small test case to show the error?
We did run the test with Spring 3.0.0 before Camel 2.2.0 released.
BTW, can you try the latest released Spring 3.0.2.RELEASE to check if
the error still there?

We run our Camel 2.2.0 app with Spring 3.0 (3.0.1 and 3.0.2 now) without
problems.
