Two workerRole in one instance

Question

Hi,

I have created azure project in eclipse Helios. 

Now I want to use two workerRoles for two Tomcat. One is tomcat7.0.27 with one project and another one is tomcat5.0.28 with another project.

When I run RunInEmulator.cmd I want to run this two tomcat.

Basically I want to run two projects with two different tomcat version in One Instance.

Please tell me how to do this.

Thanks in Advance

Answer 1

Maybe you can try to spin two processes and each will start its own tomcat server with own Input Endpoint. This this is possible but I have never try it, so you have to research.

Here is some how-to from Steve Marx http://blog.smarx.com/posts/using-other-web-servers-on-windows-azure

Hope it helps Petr

Hi,

Set two endpoint port say 81,82 in the worker role configuration

Install Java, tomcat 7.0.27, tomcat5.0.28 via startup script

Now in the Tomcat 7.0.27 make the port to 81 and  tomcat5.0.28 to 82

OnStart method listen to the ports 81,82

            ServicePointManager.DefaultConnectionLimit = 12;

            TcpListener TomcatPortListener81 = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["TomcatWeb81"].IPEndpoint);
            TcpListener TomcatPortListener82 = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["TomcatWeb82"].IPEndpoint);

            TomcatPortListener81.Start();    
            TomcatPortListener82.Start();

            return base.OnStart();
        }

This should make things work.
