Hi everyone,

I'm trying install cluster for jboss. I followed the instructions as described in the following documents: https://docs.jboss.org/author/display/AS71/AS7+Cluster+Howto.

I have one master and one slave defined. I can start-up the master and when I start-up the slaves, the correctly authenticate to the master.

My problem is I cannot request to my web service when I stop one of my nodes.

I deployed cluster-demo and my_ear-xxx.ear (my web services).

This is my enviroment:

_ Jboss AS 7.1.1

_ mod_cluster 1.2.0 : (win-x86)  (I cannot use win-x64 version, I can start httpd, however when I try access to mod_cluster_manager, httpd alway crash)

_ Windows 7 64bit (all nodes)

_ MS SQL 2008

_ SOAPSonar Personal for test web services

This is some section I config:

Master node:

- domain.xml

<server-groups>
        <server-group name="cluster-server-group" profile="full-ha">
            <jvm name="default">

And this is my httpd.conf

</VirtualHost>

Then I start master node with this param:

domain.bat -b 192.168.73.12

After Master node is started. I open one in my wsdl files to check soap:address , follow this path:

\domain\servers\full-ha-server-2\data\wsdl\my_ear-1.01.20-SNAPSHOT.ear\my_service-1.01.20-SNAPSHOT.jar\TestService.wsdl

soap:address in master node

<soap:address location="http://192.168.73.12:8180/my_service-1.01.20-SNAPSHOT/TestService/TestService"/>

After that, I start slave1 node with this param:

domain.bat -b 192.168.72.101

and this is soap:address is slave1 node

<soap:address location="http://192.168.72.101:8180/my_service-1.01.20-SNAPSHOT/TestService/TestService"/>

I can use SOAPSonar Personal and test direct on above addresses --> work fine

Because I just have 2 pc, so I installed Apache httpd on 192.168.72.101 (slave1)

Test with cluster-demo:

- Start master and slave1 node

- Access to 192.168.72.101:8888/cluster-demo. --> work fine (request is redirect to master node)

- Stop master node in Jboss Management

- Request to 192.168.72.101:8888/cluster-demo. --> work fine (request is redirect to slave1 node)

Test session replication with cluster-demo:

- Start master and slave1 node

- Access to 192.168.72.101:8888/cluster-demo/put.jsp --> work fine (request is redirect to master node)

- Stop master node

- Access to 192.168.72.101:8888/cluster-demo/get.jsp --> It doesn't work, I got session Null

Test with my web services:

- Restart master node in Jboss Management

- Use SOAPSonar Personal invoke to httpd, (http://192.168.72.101:8888/my_service-1.01.20-SNAPSHOT/TestService/TestService) - request go to slave1 node --> Work fine

- Stop slave1 node

- Re-invoke that service, - It dose not work as my expectation, I see a message "Unable connect to....".

Finally, I have some question:

session replication:

- I followed on the guide on https://docs.jboss.org/author/display/AS71/AS7+Cluster+Howto, but the result is difference. Do I miss something?

- Do somebody know which module Jboss use for session replication? HornetQ or something....?

And about my web service:

- Is possible invoke the endpoint web service through httpd? I think yes but I don't know how to config?

- I deployed my_ear to Glassfish 3, but the soap:address is quite difference. I can invoke soap:address without the name "my_service-1.01.20-SNAPSHOT". Can I config on jboss to get the result like Glassfiss? like this:

http://192.168.72.101:8888/TestService/TestService

Any Ideas Welcome.
