From Apache, you can use the "mod_jk" module to send HTTP requests to Tomcat using the "AJP" protocol, which is far more efficient that HTTP itself.
I want to do the same, but from a Java program. I want to use "AJP" because of its good performances (and Tomcat is not bad after all).
Does someone know about a Java implementation of the client side of "AJP" ?
Doesn't the tomcat-ajp.jar present in %TOMCAT_HOME%/server/lib have the AJP implementation?
There's open source Apache ajp-client available if someone needs it:
This is a java implementation of an ajp13 client, allowing to send requests to a servlet container using this protocol.
Whithout any real idea, but have you looked into Tomcat's source code, yet? Maybe Tomcat doesn't just implement the receiving end of AJP.
