Load balance in tomcat
Hi! Which is the best way to load balance, across multiple tomcat instances, without using jk conectors or apache web servers? Is there support for it in the Catalina core?

Getting only Response 400 when implementing a new connector for Tomcat 5
I´ve been trying to write a Dummy Conector to Tomcat just to learn how I must call an Adapter. It´s the first step to write a ISO-8583 connector. For that, I instancialize an Request and Response (org.apache.coyote), and set all attributes that I think to be necessary : request = new Request(); response = new Response(); ByteChunk inputChunk = new ByteChunk(); InputBuffer inputBuffer = new ByteChunkInputBuffer(new ByteChunk()); OutputBuffer outputBuffer = new ByteChunkOutputBuffer(new ByteChunk()); request.setInputBuffer(inputBuffer); response.setOutputBuffer(outputBuffer); // construct a fake request request.setResponse(response); request.setInputBuffer(inputBuffer); request.protocol().setString(HTTP/1.1); request.query().setString(); request.method().setString(GET); request.scheme().setString(http); request.serverName().setString(jlima-dsk1); request.requestURI().setString(/WebModule/servlet1); request.unparsedURI().setString(/WebModule/servlet1); request.queryString().setString(); request.setStartTime(System.currentTimeMillis()); After that, I try to invoke the container via an Adapter ( org.apache.coyote ), and finally I print the response. adapter.service(request,response); But what I got from the response is quit strange. I always get an 400 error, even when the host exist. org.apache.coyote.Response.getMessage() = No Host matches server name jlima-dsk1 org.apache.coyote.Response.getStatus() = 400 Do anybody know what I´m doing wrong ? PS: I´m using J2SDK 1.4.2 and Tomcat 5.

RES: Getting only Response 400 when implementing a new connector for Tomcat 5
The whole problem was due to the protocol attribute of the connector element, in the server.xml. We didn't set it. Actually, we extended the CoyoteConnector class, overriding setProtocol() method, which called super.setProtocol(), if the protocol didn't match our string protocol. Thanks anyway!

It doesn't deal well with type STRING. I don't think the latest 5.0.x code has these limitations anymore.

Developing a new tomcat connector
Hello! Has anyone already developed a non http tomcat connector in java? We're wondering if it is possible to implement connectors, for other protocols, to work within tomcat infrastructure. For now, we're analyzing the existing http classes, and trying to understand its functionality. The next step would be implement classes like MyProtocolConnector, MyProtocolProcessor, MyProtocolRequest, MyProtocolResponse for the new connector, so we could use a servlet based layer, inside our middleware, to process different kinds of transactions. Is tomcat too much http driven for us to try it?

RES: Developing a new tomcat connector
Yoav, One of the protocols we're going to work with is the ISO8583. Do you know some project similar to ours? We want to know the viability of implementing JAVA non http connectors... I downloaded the JK2 source code. It's in C! We have already deployed a dummy connector through the server.xml, that just echoes the request to the client.

Depending on your protocol and requirements, you might be able to reuse CoyoteRequest/Response and their Facades, and only focus on the ProtoclProcessor.
