Using a Single Servlet to Access Multiple Brokers (HTTP and HTTPS)

It is not necessary to configure multiple application or Web servers and tunnel servlets in order to access multiple brokers; you can share a single server instance and tunnel servlet among them. To do this, you must configure the imqAddressList connection factory attribute as follows:

   http://hostName:portNumber/contextRoot/tunnel?ServerName=brokerHostName:instanceName

or

   https://hostName:portNumber/contextRoot/tunnel?ServerName=brokerHostName:instanceName

where brokerHostName is the broker instance host name and instanceName is the name of the specific broker instance you want your client to access.

To check that you have entered the correct values for brokerHostName and instanceName, generate a status report for the HTTP/HTTPS tunnel servlet by accessing the servlet URL from a browser:

   http://localhost:8080/imqhttp/tunnel

The report lists all brokers being accessed by the servlet, as shown in Example C–1.
