libajp13 - A complete AJPv1.3 Java library

libajp13 is a fully featured open source library implementing the Apache JServ Protocol version 1.3 (ajp13), based on the Apache Protocol Reference.

The library has been developed from Espen Wiborg's ajp_client. At this point, most of the code has been refactored and improved to support all AJP13 packet types.

For more details, please refer to the official JavaDoc.

CPing and CPong

//Create a CPing message
AjpMessage msg = new CPingMessage();

[...]
AjpMessage reply = AjpReader.parseMessage(gotBytes);
if (reply instanceof CPongMessage) {
  System.out.println("[OK] Valid CPong");
}

Shutdown

AjpMessage msg = new ShutdownMessage();

EndResponse with session reuse set to 'true'

AjpMessage msg = new EndResponseMessage(true);

SendBodyChunkMessage

AjpMessage msg = new SendBodyChunkMessage("ABCD".getBytes());

SendHeadersMessage

List<Pair<String, String>> headers = new LinkedList<>();
headers.add(Pair.make("Content-Type","text/html; charset=utf-8"));
AjpMessage msg = new SendHeadersMessage(200,"OK",headers);

GetBodyChunkMessage

AjpMessage msg = new GetBodyChunkMessage(10);

BodyMessage

AjpMessage msg = new BodyMessage("MyStringSentAsBytes".getBytes());

ForwardRequestMessage to build a simple GET request

List<Pair<String, String>> headers = new LinkedList<>();
headers.add(Pair.make("Content-Type","text/html; charset=utf-8"));
AjpMessage msg = new ForwardRequestMessage(2, new URL("http://127.0.0.1/"), headers, null);

ForwardRequestMessage using ForwardRequestMessageGetBuilder

AjpMessage msg = ForwardRequestMessage.ForwardRequestMessageGetBuilder(new URL("http://192.168.1.1/log/"));

ForwardRequestMessage to build a PUT request with custom headers and attributes

List<Pair<String, String>> headers = new LinkedList<>();
headers.add(Pair.make("Content-Type","text/html; charset=utf-8"));
headers.add(Pair.make("CustomHeaderName","CustomHeaderValue"));
List<Pair<String, String>> attributes = new LinkedList<>();
attributes.add(Pair.make("jvm_route","3131212"));
attributes.add(Pair.make("custom_attribute","custom_value"));
AjpMessage msg = new ForwardRequestMessage(5, "HTTP/1.0", "/api/", "127.0.0.1", "localhost", "127.0.0.1", 8009, true, headers, attributes);
