Managing transactions in iPOJO or OSGi components

[tho huynh ngoc <ng...@gmail.com>]

Hi,

I define a transaction is a set of continuous activities (one method or set
of methods) in a component.

I wrote a simple example as follows:

//service interface
public interface Hello {
    String sayHello(String name);
    String sayBonjour(String name);
}

//implementation service
@Component
public class HelloImpl implements Hello {

  public String sayHello(String name) {
  //start local transaction
        return "hello " + name;
  //finish local transaction
    }
  public String sayBonjour(String name) {
  //start local transaction
        return "bonjour " + name;
  //finish local transaction
    }
}

//client
@Component
public class Client {

    Hello client;

    public ClassTransaction() {
        //start local transaction
        client.sayHello("world");
        client.sayBonjour("le monde");
        //finish local transaction
    }
 }

In this example, there are local transactions in the components HelloImpl
and Client. I define that global transaction of the system consists of a
set of local transactions through all components.

How to manage transactions (global transaction and the local transtions in
this example) in OSGi or iPOJO ?
