HTTP Service is the most lightweight and unrestricted remote service: it supports POST and GET requests to a predefined URL. The result is retrieved as is and rendered as a webpage.


    Example 1

    This example shows how to call through an HTTP web service. In this case, the pKa values of a molecule are calculated.


    An example calculation with this web service can be found below.


    Example 2

    This example shows how to reach the functionalities of through HTTP API.

        HTTPServiceDescriptor descriptor = new HTTPServiceDescriptor();
        descriptor.addArgument(ServiceArgument.createArgument("mol", ""));
        descriptor.addArgument(ServiceArgument.createArgument("special", ""));
        descriptor.addArgument(ServiceArgument.createArgument("pka_width", 0));
        Object result = null;
        try {
            result = descriptor.getServiceHandler().callService(descriptor, "c1ccnccc1", "pka", 300);
        } catch (ServiceException e) {
           System.err.println("Service call failed.");
        System.out.println("Synchronized call returned: " + String.valueOf(result));
        descriptor.getServiceHandler().callService(descriptor, new AsyncCallback<String>() {
            public void onSuccess(String result) {
                System.out.println("Aynchronous call returned: " + result);
            public void onFailure(ServiceException caught) {
                System.err.println("Asynchronous call failed.");
        }, "c1ccnccc1", "pka", 300);
