Does Jaxb With Spring Remoting (proxy) work ?

[Pietroforte]

1) When i configure client to use the producer template with jaxb, it works fine. 2) When i change to proxy configuration, it doesn't work. The (un)marshal, in the camel-server.xml, works with Template, but doesn't work with Proxy. ... If i want my Proxy working, i have to remove the (un)marshal of the route and utilize a method in my inteface that receives a common type, such a integer or a string, but not a type generated by jaxb. Some clues?

Hi

I think you need to provide a bit more details such as

- Version of Camel, OS, JDK, JAXB etc.
- What goes wrong, stacktrace / error etc.
- Configuration of working vs. non working

Hi

And it may also be a pure spring related issue how to work with JAXB
over it using its proxy features.
Although you can use Camel as well to expose such a proxy.

Hi Claus,

I made my tests based on the tutorial on spring remoting with JMS by Martin Gilday.

Version of Camel: apache-camel-1.6.1
OS: windows xp
JDK: 1.5
JAXB:
message broker: apache-activemq-5.2.0 (i've tryied with mqseries but had the same behavior

The problem happens when, after i start the server (camel-server.xml) and the client(
camel-client-remoting.xml), i try to comunicate with an interface of the server that receives an object generated by jaxb. The comunication in the side of client stops here, with a message in console: [DEBUG] joining on thread Thread[Thread: 1 org.apache.camel.component.jms.JmsComponent@ac0b08,5,

and, in the side of server, with the apache camel already started, nothing happens.

I think that the route subtags (un)marshall are causing this non expected behavior.

To the transport of the object works fine, i have to remove the (un)marshal and manually serialize the classes generated by jaxb, so i don't tranport xml but objects serialized. Working this way, i have a limited use of jaxb.

my dependencies are basically:

com.ibm.mqjms 5.3.13 com.ibm.mq 5.3.13
org.apache.camel camel-core 1.6.1 camel-jms 1.6.1 camel-jaxb 1.6.1 camel-spring 1.6.1
org.apache.activemq activemq-core 5.2.0
org.apache.xbean xbean-spring 3.5
cglib cglib-nodep 2.1_3
org.springframework spring-core 2.5.6 org.spring-orm 2.5.6
javax.xml.bind jaxb-api 2.0
com.sun.xml.bind jaxb-impl 2.0.3 com.sun.jdmk jmxtools1.2.1
org.jvnet.jaxb2.maven2 maven-jaxb2-plugin 0.7.1

Hi, If I get you right the problem is that the classes generated by jaxb do not implement Serializable?! This can be changed by adding custom binding for jaxb. I haven't tried out how to use this with Camel but I guess this should be a starting point. You can also google for jaxb java class serializable.
Should be something like this:

<?xml version="1.0" encoding="UTF-8"?>
<jxb:bindings version="2.0" 
              xmlns:jxb="http://java.sun.com/xml/ns/jaxb" 
              xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
  <jxb:bindings > 
    <jxb:globalBindings> 
       <jxb:serializable uid="1" />
    </jxb:globalBindings> 
  </jxb:bindings> 
</jxb:bindings>

Save the snippet above e.g. as my_binding.xjb in the resource directory where the xsd schema files are located (*.xjb is the default extension that is picked up by the maven-jaxb2-plugin, see https://maven-jaxb2-plugin.dev.java.net/docs/guide.html for more information). Hope this helps.

Hi.

I don't know exactly why, but when i use camel producer template with jaxb, i don't have to serialize the classes and i can marshal and unmarshal with jaxb dataformat normaly.

But, when i introduce de proxy and remove the producer template, start the serialization problem and marshal and unmarshal do not work.

Did you do something like this?

Tks!

Hi,

Can you show us how your create the producer template and your routing
rule ?
