Hi,
I'm quite new to ECF. I can't ran the remote service examples.
Following is the exception:

Hi xxlu,

This NPE looks to be because the discoveryService is null in the
following code:


[89]discoveryService = Activator.getDefault().getDiscoveryService(5000);
[90]
[91]final String serviceName = System.getProperty("user.name") +
[92]System.currentTimeMillis(); //$NON-NLS-1$
[93]final IServiceID serviceID =
ServiceIDFactory.getDefault().createServiceID(discoveryServi ce.getServicesNamespace(),
getCompleteServiceType(), serviceName);

It is possible that the discovery service is null because of either

a) the jmdns provider bundle is not included in the set of bundles
needed for this app (it must be included so that the discoveryService
can be started and found)

b) the 5000ms timeout can be too short. In all the local tests I've
done 5000ms (5 sec) is long enough, but it is possible that under heavy
load conditions it's not long enough...and the jmdns bundle does not
have sufficient time to start. I've already changed the timeout to
15000ms and committed to HEAD and Release_2_0 branch. If you get the
source to org.eclipse.ecf.examples.remoteservices.server plugin:

Repository path: /cvsroot/technology
Module:
org.eclipse.ecf/examples/plugins/org.eclipse.ecf.examples.re moteservices.server

And get these fixes.

I am also new to ECF and I'm having problems running the example (even with
the 15 sec timeout).

Here are the steps I did:

1. I imported org.eclipse.ecf.examples.remoteservices.client,
org.eclipse.ecf.examples.remoteservices.common and
org.eclipse.ecf.examples.remoteservices.server from CVS into a new
workspace.

2. I modified the Generic Remote EnvironmentInvo Server.launch configuration
to only have the three above workspace_bundles.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<launchConfiguration type="org.eclipse.pde.ui.EquinoxLauncher">
<booleanAttribute key="append.args" value="true"/>
<booleanAttribute key="automaticAdd" value="false"/>
<booleanAttribute key="automaticValidate" value="false"/>
<stringAttribute key="bootstrap" value=""/>
<stringAttribute key="checked" value="[NONE]"/>
<booleanAttribute key="clearConfig" value="false"/>
<stringAttribute key="configLocation"
value=" ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/Gen eric

<booleanAttribute key="default_auto_start" value="false"/>
<intAttribute key="default_start_level" value="4"/>
<booleanAttribute key="includeOptional" value="true"/>

<stringAttribute key="workspace_bundles"

</launchConfiguration>

3. Then I right-click the modified launch configuration and run Debug.

=> I get the following failure:

Hi Anders,

Sorry about the slow reply.

You are not missing anything. At first glance, this seems to be some
problem with interaction between the jslp and the jmdns-based discovery
providers that is preventing this discoveryService lookup from
succeeding (and resulting in a NPE). I've created bug for this here:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=247238

Please join that bug and we'll track progress there.
