This small library is a Java AJP client code extracted from Apache Tomcat test harness. This is not yet a general-purpose client connector; it takes more work to turn it into one.
First, look at AJP Protocol Reference to understand how the protocol works.
The following code examples shows a usage of this library in the original Tomcat test code:
// open connection
SimpleAjpClient ac = new SimpleAjpClient();
ac.connect("localhost",10059);
// create a message that indicates the beginning of the request
TesterAjpMessage forwardMessage = ac.createForwardMessage("/test.xxx");
forwardMessage.addHeader("content-length","0");
forwardMessage.end();
for (int i = 0; i < 2; i++) {
TesterAjpMessage responseHeaders = ac.sendMessage(forwardMessage);
// Expect 3 packets: headers, body, end
validateResponseHeaders(responseHeaders, 200);
TesterAjpMessage responseBody = ac.readMessage();
validateResponseBody(responseBody, "Hello");
validateResponseEnd(ac.readMessage(), true);
// Give connections plenty of time to time out
Thread.sleep(2000);
// Double check the connection is still open
validateCpong(ac.cping());
}
ac.disconnect();
