I created java program in an OSGi plateform. The program implements
communication between a sever and client through web services using
cxf-dosgi-ri-singlebundle-distribution (1.2.0). Tutorial steps provided by
--- http://cxf.apache.org/distributed-osgi-greeter-demo-walkthrough.html
were followed to creat the link establishing the server client
relationship. The server bundle provides some services through the Internet
and a list of clients subscribed to the service as listeners. The server
notifies these listeners (clients) whenever an event occurs. The code below
is used to export the OSGI service as a web service. The service is
implemented by TransInUse(). Clients subscribe to this service as listeners.
Dictionary props = new Hashtable();
TransInUse inUse =new TransInUse();
props.put("service.exported.interfaces", "*");
props.put("service.exported.configs", "org.apache.cxf.ws");
props.put("org.apache.cxf.ws.address",
http://localhost:8080/translatorIsBeingUsed);
addExportedService(ITransInUse.class.getName(), inUse, props);
The service is imported by the following lines of code:
ITransInUse using = (ITransInUse) getImportedService(ITransInUse.
class.getName());
TransInUseListener listener = new TransInUseListener ();
using.addListener(listener);
The method in the listeners is called by the the following code:
ITransInUseListener is the interface which is implemented by the listeners.
public void translatorIsBeingUsed(){
for (Iterator i = listeners.iterator(); i.hasNext();)
((ITransInUseListener) i.next()).translatorIsBeingUsed();
}
However, when the server calls the method implemented by the listeners, I
get an error
Could someone please tell me what I am doing wrong here. Thanks
However, when the server calls the method implemented by the listeners, I
get an error message pasted below . Could someone please tell me what I am
