Hi all,
I'm facing the following issue under OSGi environment: let's say I have a
bundle A exporting com.mybiz.example package. This package, in its 1.0.0
version, contains a bean class MyBean so that
public class MyBean {
int var;
public MyBean() { }
public int getVar() { return var; }
public void setVar(int v) { var = v; }}
Bundle B exports an interface MyService which uses MyBean:
public interface MyService {
public MyBean getMyBean();}
Note: in our architecture, MyBean must be a class and not an interface.
Bundle C uses MyService as a declarative service in this way:
private AtomicReference<MyService> _serv = new
AtomicReference<MyService>();public void addMyService(MyService serv)
{
//this method is the one called by declarative services when Bundle B
is started
_serv.set(serv);}
public void run() {
...
MyBean x = _serv.getMyBean();
//use x ...}
Now the problem arises if I need to do a hot fix on MyBean class. Let's say
I need to add a field and some methods. Then, I've got a running OSGi
environment where bundles A,B,C are deployed.
My requirement is that I cannot stop any bundle.
So, under these hypotheses, I deploy a new version of my bundle A, say
A_1.1.0.jar. Now I'm not able to make bundle C to use the new version of
MyBean class contained in A_1.1.0.jar.
How can I do it?
Thank you very much!
Best regards
cghersi
