#51 Sometimes NoSuchServiceException v0.2.10
We have upgrade the ITADate example to be used with
servENT v0.2.10.
We have a simple interface,
public interface IDateInterface {
public Date getITADate();
}
a very simple Implementation,
public class DateServiceImpl implements IDateInterface,
Adapter
and a client that uses the background search with the
new ClientHelper
ClientHelper ch = new ClientHelper(new URL("http://" +
machine + ":2728"));
ch.getProxy(IDateInterface.class, new String[] {
"itadate0_2_10" }, 10000, 13, this);
The deployment props is this,
applicationName=itadate0_2_10
adapter=org.dbe.demos.ita.date.DateServiceImpl
smid=itadate0_2_10
and the service is deployed successfully in the servENT.
When we run the client, there is two problems:
- Sometimes the service is not found
("org.dbe.servent.NoSuchServiceException: The service
proxy is not available"), see traces for Test1
- With no changes, we run the client again and it works
but notice in the gotProxy method, the proxy is null
Here you have log traces for all, in case you need you
can download source code from CVS
(http://dbe.ita.es/viewcvs/dbe/dev/itademos/exe_0_2_10/date/)
Thanks in advance,
ITA
