Service grid client need service implementation deployed locally

[amdam23000 <62...@qq.com>]

Hi,
I have tried to use service grid funtionality with one ignite server node
and one ignite client node(clientMode=true) .

After some simple tests i found that the client errored out without the
service implementation calsses deployed locally (xximpl.class not found ).
When implementation classes was included the remote service call worked
fine.

Also i tried to debug to find how service call is invoked remotely and found
that the task executed was of type GridPeerDeployAware (though i have
disabled peerClassLoading...).

So far as i know, java interface based rpc should separate interface and
implementation to decouple our systems. Is there anything special for ignite
to do so?


Thanks,
Jason

Hi, Jason.

Yes, I have successfully tried to launch independent client without service
implementation in a classpath.

Could you publish your test project to show the problem to the community?

Regards,
Ed.

Hi Eduard, 

i just follow the service grid sample( link
<https://apacheignite.readme.io/docs/service-example>  ), so the result has
no link to implementation at all.

Or did u have a try on the service grid sample and succeeded with a
independent client which has no implementation class?


Thanks,
Jason

Hi Jason.

Is it possible that your result contains links on you service
implementation?
It can describe such issue.

Ed.

Hi vkulichenko,

I have only one single server node and one client which invokes service.

When there is no implementation class in client, the exception will occur;
When i place implementation class in client, the exception will be gone.

Also i have placed some braekpoint in server node code, found the service
was actually called in server node though implementation class also exists
in client node (It means the service grid works).

The exception is as below:
<http://apache-ignite-users.70518.x6.nabble.com/file/n7815/capture1.png> 

Client config:
<http://apache-ignite-users.70518.x6.nabble.com/file/n7815/clientConfig.png>

Hi Jason,

Services are not deployed on the client nodes unless you explicitly ask for
that. Can you show the exception?
