Interenent Explorer from Java

Question

Hello! I need to post data (for login data) using ie (internet explorer) and then to display the browser to user.
I use JACOB for browser control and here is the code:
package testJACOB;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.SafeArray;
import com.jacob.com.Variant;
class IETest
public static void main(String[] args)
ActiveXComponent ie = new ActiveXComponent(
"clsid:0002DF01-0000-0000-C000-000000000046"); //IE
Object ieo = ie.getObject();
String path = "http://localhost:3333/portal/Login";
String postData = "userName=uuu&password=ppp";
String content = null;
try
content = URLEncoder.encode(postData, "UTF-8");
catch (UnsupportedEncodingException e)
e.printStackTrace();
SafeArray sa = new SafeArray(Variant.VariantByte, content.length());
sa.fromByteArray(content.getBytes());
Variant[] arg = new Variant[]{
new Variant(path),
new Variant(),
new Variant(),
new Variant(sa),
new Variant("Content-type: application/x-www-form-urlencoded") };
ie.invoke("Navigate2", arg);
Dispatch.put(ieo, "Visible", new Variant(true));
Browser sucsefully opens, but I get 'null' post data in my web-app. It seems that web-app got nothing in http-request for post data.
What is wrong in my code?
Thank you very much.
Vladimir.

WundahWheel,
learn first how to use interfaces of WebBrowser Control. Here is a simple example. Substitute in NJAWIN WebBrowser Example (file WebBrowserComponent.java)
public void DocumentComplete(
          Object srcObj,
          DispatchPtr pDisp,
          ObjectRef URL)
          throws COMException {
        System.out.println("DocumentComplete");
        if (doc == null && control != null) {
            doc = new MSHTML.IHTMLDocument2(control.getDocument());
            if (!doc.isNull())
                DispatchPtr disp = doc.getScript();
                IHTMLWindow2 win = new IHTMLWindow2(disp);
                win.showModalDialog("http://www.google.com");
                doc.addEventListener(
                    HTMLDocumentEvents2.class,
                    new DocumentListener());
            else {
                doc = null;
                return;
}While invoking "DocumentComplete" event you will see WebBrowser Dialog.
