Question

I hava a pure Java application which publishes a webservice without needing any Application server. How can I configure the Apache Http Loadbalancer to forward requests to servers on which this application is installed.

I can handle it when I deploy an webservice over an Application Server such as Glassfish. But I do not know how to do it with pure Java application.

You should just be able to use http:// instead of ajp:// in your balancer config, like:

<Proxy balancer://myApp>
  BalancerMember http://47.168.96.31:2020 route=r1
  BalancerMember http://192.168.0.2:2020 route=r2
</Proxy>

or directly forward with proxy like:

ProxyPass / balancer://myApp
ProxyPassReverse / balancer://myApp

Let’s say apache is on 47.168.96.31, then you’d access the service as http://47.168.96.31/StockQuote/StockQuoteService

If you’d rather have the service respond at http://47.168.96.31/, you could do:

ProxyPass / balancer://myApp/StockQuote/StockQuoteService
ProxyPassReverse / balancer://myApp/StockQuote/StockQuoteService
