Hello,
Thanks for reply.
I have done the look up programmatically as said below.
The code works.
I have one more issue, while testing one scenario:
The current configuration is:
I am having Two clusters clusterA and clusterB
clusterA is having the war file and this is deployed one separate machine(say machine X)
in a JBOSS instance.
clusterB is having the ear. This is deployed as farm deployment and the there are two
JBOSS instances on separete machines.(say machine Y and Z)
So, there are three machines each having JBOSS instance.
Further, Apache HTTP server is deployed on machine X
Cluster A has one node and B has two nodes.
The test scenario is :
we have a JSP page which makes a call to the session bean.
The session bean has a for loop that counts and prints counter till 40.
We hit one request
1. One node in clusterB starts processing(Node Y)
2. Now, we down this node.
3. The request is shifted to other node(Node Z)
4. We start the previous node(Node Y) and then close the node(Node Z) which is
processing
Expected. The node A should again start processing the request
Actual: error occurs on the node X of clusterA i.e where the war file is deployed.
NOTE:
Also, pLease confirm if Jboss handles such test scenario.
Is there any limit while toggling the request between the nodes.
Error:
