hi, there:
In my project, I open a browser window via ActiveX and the browser will
open a webpage(written by jsp). The webpage will create a session
variable. In this page, there is a hyperlink to another jsp page (open a
new IE window like that <a href="another.jsp" target=_blank>another
page</a>). In the new page, the session variable will be got from session,
but fail to got it. The session variable is null. How can I got the
variable? The www server I use is BEA Weblogic 7.0. The browser is IE6.0.
Thanks for your answer.

1) you need to open the new window in the same process
2) you need to register this new browser as a top level browser
See below for an example of how this is done. See also bug report 29396 for
a more detailed discussion.
import org.eclipse.swt.*;
import org.eclipse.swt.internal.ole.win32.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.ole.win32.*;
import org.eclipse.swt.widgets.*;
public class PR29396 {
static final int NewWindow2 = 0x000000fb;
static final int RegisterAsBrowser = 0x228;
public static void main(String[] args) {
final Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
OleFrame frame = new OleFrame(shell, SWT.NONE);
OleControlSite site = new OleControlSite(frame, SWT.NONE,
"Shell.Explorer");
site.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
// create automation object
OleAutomation iwebbrowser = new OleAutomation(site);
// register the new window as a top-level browser for target name
resolution
iwebbrowser.setProperty(RegisterAsBrowser, new Variant(true));
// navigate to URL
int[] rgdispid = iwebbrowser.getIDsOfNames(new String[]{"Navigate2",
"URL"});
int dispIdMember = rgdispid[0];
Variant[] rgvarg = new Variant[1];
int[] rgdispidNamedArgs = new int[1];
rgdispidNamedArgs[0] = rgdispid[1];
String url = "http://your_url/index.jsp";
rgvarg[0] = new Variant(url);
iwebbrowser.invoke(dispIdMember, rgvarg, rgdispidNamedArgs);
rgvarg[0].dispose();
// free automation object
iwebbrowser.dispose();
// add listener in case this window opens a new window
final OleListener[] listener = new OleListener[1];
listener[0] = new OleListener() {
public void handleEvent(OleEvent event) {
Variant[] args = event.arguments;
switch (event.type) {
case NewWindow2: {
// Create a new window
Shell shell2 = new Shell(display);
shell2.setLayout(new FillLayout());
OleFrame frame2 = new OleFrame(shell2, SWT.NONE);
OleControlSite site2 = new OleControlSite(frame2, SWT.NONE,
"Shell.Explorer");
site2.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
// create automation object
OleAutomation iwebbrowser2 = new OleAutomation(site2);
// register the new window as a top-level browser for target name
resolution
iwebbrowser2.setProperty(RegisterAsBrowser, new Variant(true));
// Hack to get IDispatch address of embedded web browser
Variant temp = new Variant(iwebbrowser2);
IDispatch idispatch = temp.getDispatch();
idispatch.AddRef();
// Copy Idispatch address to ppDisp
Variant ppDisp = args[0];
int byref = ppDisp.getByRef();
COM.MoveMemory(byref, new int[] {idispatch.getAddress()}, 4);
// free automation object
iwebbrowser2.dispose();
// add listener in case this window also opens a new window
site2.addEventListener(NewWindow2, listener[0]);
shell2.open();
}
}
for (int i = 0; i < args.length; i++) {
args[i].dispose();
}
}
};
site.addEventListener(NewWindow2, listener[0]);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}
