The issue of Webforms and Internet Explorer add-ons

Microsoft is pushing out Internet Explorer 7 (IE 7) as a ‘High Priority’ update through its ‘Automatic Updates Patch Distribution Service’ for Windows XP users at the moment. This produces issues for Oracle Webform users, who may unknowingly have their IE6 installation upgraded to IE7. One of these users was me. Last week I upgraded Internet Explorer to version 7 without considering the impact. Well I know now, I could not connect to my webforms application anymore using IE7.  I always got a jvm.dll error and the application crashed before it was initialized. So how to overcome....

There might be several reasons the crash occurs.

You may have unwanted add-ons like Microsoft Live Toolbar running on your machine. Disable the add-ons one by one, restart IE and check if the error is resolved

IE 7 might not be supported for your JRE environment. Uninstall IE 7 and continue using IE 6 until the JRE version is supported. Further more to prevent that IE 7 will be pushed again on your computer install the  blocker toolkit of Microsoft. The blocker toolkit that may be installed by administrators can prevent the automatic delivery of IE 7 to the users desktops. Although the application of the blocker software prevents the automatic download of IE 7, it does not stop users manually downloading and installing it themselves.

Oracle advises:

"If your Microsoft ‘Automatic Updates’ facility is set to ‘Automatically download recommended updates for my computer and install them’, we highly recommended you install the blocker toolkit. If your Microsoft ‘Automatic Updates’ facility is set to ‘Download updates for me, but let me choose when to install them’, it may still be useful to install the blocker toolkit as an extra safety measure.

Companies that have their own Windows patch update server (e.g. Windows Server Update Services (WSUS) or SMS 2003) do not need this blocker. They should just manage the IE 7 update so that it is not deployed until certification of IE 7 has been announced by Oracle. "
