Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Could you tell me how to solve the above issue ?

Thanks and Regards, Narayan.

Answer 1

I think that error occurs because of mod_jk. Although that error occurs, you can call your web application via apache server.

Usually, we use AJP connector to integrate Apache to Jboss with port(8009). So, you have to pass your web application address at etc/httpd/conf.d/proxy_ajp.conf like ProxyPass /mywebapp/ ajp://jbossserverip:8009/mywebapp/

From your browser, type your apache server address apacherserveripaddress/mywebapp/
