RE: Making amf calls from java instead of flash

ASTranslator provides a Java interface to ASObjects, I've used these in JUnit test cases to test my interface.

See http://carbonfive.sourceforge.net/astranslator/api/com/carbonfive/flash/package-summary.html#documentation

This might help you get started:

    protected AMFMessage sendRequest(String service, String method, Object[] arguments)
    throws Exception {
        Object[] asArgs = new Object[arguments.length];
        ASTranslator translator = ASTranslatorFactory.getInstance().getASTranslator();

        for(int i = 0; i < asArgs.length; i++) {
            asArgs[i] = translator.toActionScript(arguments[i]);
        }

        AMFBody body = new AMFBody(service + "." + method, "/1", asArgs, AMFBody.DATA_TYPE_ARRAY);
        AMFMessage requestMessage = new AMFMessage();
        requestMessage.setVersion(0);
        requestMessage.addBody(body);

        ByteArrayOutputStream baOutputStream = new ByteArrayOutputStream();
        DataOutputStream outputStream = new DataOutputStream(baOutputStream);
        AMFSerializer serializer = new AMFSerializer(outputStream);
        serializer.serializeMessage(requestMessage);

        PostMethod post = new PostMethod("http://localhost/gateway");
        post.setRequestBody(new ByteArrayInputStream(baOutputStream.toByteArray()));
        post.setRequestContentLength(baOutputStream.size());
        post.setRequestHeader("Content-type", "application/x-amf");

        int result = m_httpclient.executeMethod(post);

        DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(post.getResponseBody()));

        AMFDeserializer deserializer = new AMFDeserializer(inputStream);
        AMFMessage toReturn = deserializer.getAMFMessage();
        post.releaseConnection();

        return toReturn;
    }

http://localhost/gateway is where my openAMF servlet is listening. I use apache http client to send the messages.

Subject: [Openamf-user] Making amf calls from java instead of flash


I need to be able to make amf calls from java instead of from flash.  I have an openamf project and we are going to production in a couple of months.  I need to stress the J2EE container, so I am working on a utility.  Do to the complexity of the stress utility I am writing it in Java.  I was hoping I could make amf calls from java using the api or creating my own.  

Is there anything already out there so I don't have to reinvent the wheel?  If not, I was hoping someone could point me in right direction for putting the calls together.

Thanks,

S. Jackson
