Accessing exchange from producer template

[trivedi kumar b <Tr...@ge.com>]

Hi,

I have a bean that is being invoked from a route and this bean has got
producer template.. and I want the access to exchange object to retrieve
properties that is being set before in the route. So I have written a small
piece of code (method) that returns me the exchange object.. pls let me know
if there is a better to get the exchange object.

private Exchange getExchange() {
        Exchange exchange = template.send(new Processor() {
            public void process(Exchange arg0) throws Exception { }            
        });
        return exchange;
    }

Hi

You want to get those properties in the bean, and before you use the
producer template?

You can use bean parameter binding
http://camel.apache.org/parameter-binding-annotations.html

public void myMethod(String body, @Properties Map properties);


Or just add Exchange as a parameter to your bean.

public void myMethod(String body, Exchange exchange);


PS: Chapter 4 in Camel in Action covers using beans in great details
