The website can not be displayed Forms 10.1.2.3 / IE8 / Windows 7

Question

Hi,
first the problem description:
I run a Forms-web application from a shortcut on the desktop.
For example:
"C: \ Program Files (x86) \ Internet Explorer \ iexplore.exe" "http://k1r.bf.ia:7778/forms/frmservlet?config=sdb_Java"
The resolution is a DNS server. Even if I use the IP Address, I have the same problem:
In IE appears
*"The website can not be displayed"*
when I press F5 it runs all and the page is displayed. why ???????
Forms 10.1.2.3
Client Windows 7 32Bit
IE 8.0.7600
Java 1.6.0_23
Formsweb.cfg:
basehtml          = d:/orabase/oas/forms/webutil/server/webutiljpi.htm
jpi_classid          = clsid:8AD9C840-044E-11D1-B3E9-00805F499D93
jpi_mimetype     = application/x-java-applet;jpi-version=1.6
Since it works fine with Firefox 3.6.13,
someone can help me ?

Answer 1

I looked at our code and this is what we do to show any URL (like a Reports PDF or another website) in a new browser window from Forms.
We've implemented a pluggable Java component which is called from Forms via set_custom_item_property to show a given URL in a new browser window.
set_custom_item_property('TEST.BROWSERBEAN', 'SHOW_URL', l_url);
In the pluggable Java component the code invoked when setting that property first tests the Java runtime version:
a. if it's 1.6.0_23 or higher then it simply calls Applet.getAppletContext().showDocument(<url>, "_blank");
Java 1.6.0_23 fixes bug 6946479 by opening the browser window in the same iexplore.exe process via an IE add on API. This reestablishes the implementation behaviour as it's been with Java 1.6.0_17 and below, i.e. the bug exists in 1.6.0_18-1.6.0_22.
The side effect of this bug fix is that by calling showDocument() (or the Forms API show_document) the problem with IE being unable to correctly load a site during the startup of the browser gets circumvented since there is no new browser process.
Thus - if it's an option for you - just use Java 1.6.0_23 on the clients.
For a description of the bug look e.g. at the following site. The description is E-Business Suite specific but it's a Java plugin bug:

Bug in the Sun Java bug database:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6946479
b. if the Forms applet runs on Java 1.6.0_22 or below our PJC implementation uses Java-to-Javascript communication to run a Javascript function to open the URL in a new window in the same browser process, e.g.:
                    JSObject jsWindow = JSObject.getWindow(this.applet);
                    jsWindow.eval("window.open('" + urlToShow + "', '_blank');");
I hope this helps.
Regards,
Andreas
