The code example below requests the resource of the HTTP server start page, if such is present.

import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceReference;
import com.prosyst.mbs.services.http.HttpHelper;

                      . . .

  BundleContext bc = null;
  ServiceReference helperRef = null;
  HttpHelper helper = null;

                      . . .

    // Retrieving the HTTP Helper from the server framework
    helperRef = bc.getServiceReference("com.prosyst.mbs.services.http.HttpHelper");
    helper = (HttpHelper)bc.getService(helperRef);

    // Processing a simple HTTP Request
    String input = "GET / HTTP/1.0\r\n\r\n";
    byte[] outputBytes = helperServ.getOutput(input.getBytes());
    String output = new String(outBytes);

                      . . .

You can retrieve the essential attributes of an alias using the HttpHelper interface and the AliasProperties interface. For clarification, consider the following code example:

import org.osgi.framework.BundleContext;
import org.osgi.framework.ServiceReference;
import com.prosyst.mbs.services.http.HttpHelper;
import com.prosyst.mbs.services.http.AliasProperties;

  BundleContext bc = null;
  ServiceReference helperRef = null;
  HttpHelper helper = null;
  String servName = "com.prosyst.mbs.services.http.HttpHelper";

                      . . .

    // Retrieving the HTTP Helper from the server framework
    helperRef = bc.getServiceReference(servName);
    HttpHelper helper = (HttpHelper) bc.getService(helperRef);
    AliasProperties[] aliases = helper.getAliases();

    // Extracting registered aliases
    for(int i=0; i<aliases.length; i++) {
      String aliasName = aliases[i].getAlias();
    }

                      . . .
