I tried to inject the service as you suggested (which also lets me preserve the interface) by implementing KernelControllerContextAware as such:
public class ServiceA implements KernelControllerContextAware {
private KernelControllerContext controllerContext;
private Logger log;
private String val;
private ServiceB svcB;
public ServiceA() {
log = Logger.getLogger(getClass().getName());
}
public String getValue() {
return val;
}
public void setValue(String val) {
this.val = val;
}
public ServiceB getServiceB() {
return this.svcB;
}
public void setServiceB(ServiceB val) {
this.svcB = val;
}
public void init() {
try {
log.info("lookup = " + controllerContext.getController().getInstalledContext("SvcB"));
} catch (Throwable e) {
e.printStackTrace();
}
log.info("init-ed");
}
public void create() {
log.info("created");
}
public void start() {
log.info("started");
}
public void stop() {
log.info("stopped");
}
public void destroy() {
log.info("destroyed");
}
@Override
public void setKernelControllerContext(KernelControllerContext arg0)
throws Exception {
this.controllerContext = arg0;
}
@Override
public void unsetKernelControllerContext(KernelControllerContext arg0)
throws Exception {
this.controllerContext = null;
}
and ServiceB.java is:
package com.raf.test;
import org.jboss.logging.Logger;
public class ServiceB {
private Logger log; private String val;
public ServiceB() { log = Logger.getLogger(getClass().getName()); } public String getValue() { return val; }
public void setValue(String val) { this.val = val; }
public void init() { log.info("init-ed"); } public void create() { log.info("created"); } public void start() { log.info("started"); } public void stop() { log.info("stopped"); } public void destroy() { log.info("destroyed"); }}
and here's the deployment descriptor:
The problem is 'getInstalledContext("SvcB")' doesn't work. It returns a null. For "SvcA" it returns the pojo instance - which leads me to believe there's some scoping at play and that I need to probably search in the 'root' scope of the <deployment> file for my bean, but I'm not familiar how to do that, and I couldn't find some simple example to show me how to do that....
My original point is - I don't want to inject the service via the descriptor - I know I can do <inject bean="SvcB"/> in SvcA, but I don't want to do that - this is why I asked, is it possible to somehow locate "SvcB" from inside "SvcA"?
Thanks!
Martin
