How to access Apache Ignite service grid services from a J2ee
application server
Hi team,
I am trying to use Apache Ignite for project and I am trying to access the
apache-ignite service-grid services, which are exposed through the service
nodes from out side the cluster from an application deployed on a J2ee
application server .
Looking through the documentation and research I did in this regard I could
not find any way of achieving this.
Will this integration be achievable?
If not what would be the best approach to get data from Ignite services to
a J2ee app .

Hi,
Have you tried to use TcpDiscoveryVmIpFinder instead of
TcpDiscoveryMulticastIpFinder
?

Thanks for the node on singleton bean, i did so and it seems to be responding
now.
Please NOTE that I am using " -Djava.net.preferIPv4Stack=true" for all my
nodes viz: data-node,service-node and the j2ee -app server which is running
the singelton-bean.
However I STILL keep seeing the below logs continuously on my
Ignite-Data-Node.

Make sure that you are creating an Ignite client within a singleton bean.
Kind regards,

Could you describe or share the code where and how you create Ignite client?

Well, before you request a service proxy you need to get an Ignite instance
first so there is no way to avoid creating that Ignite instance somewhere.
Do you anticipate/observe any problems with this approach?
Kind regards,

Hi Alex,
Thanks for the info , i have read through and tried using service-proxy .
However to an instance of the service proxy first i need to get an access
to the "ignite" instance-object which i can only get through
"Ignition.start()" which internally triggers off a different tread. I want
to avoid this different tread being triggered.
So basically if i can get an instance of "ignite" or "serviceproxy" without
doing "Ignition.start()" that should solve the problem. Is there a way to
do this?

Re: How to access Apache Ignite service grid services from a J2ee

Posting from the duplicate thread
I am trying to access services that i have exposed over the apache-ignite
service-grid from out side the ignite-cluster.
I am trying to access them from a J2ee application running on a Wildfly10
j2ee application server.
However when i am trying to use the services-proxy api , it is starting a
new ignite-specific jvm from within my application-server and the 2 jvm are
running .
IS there a way to expose service-grid services to outside ignite-cluster ?
If not what would be the best/recommended way of accessing apache-service
grid from outside the ignite-cluster.
Kind regards,
Alex
