Java SE (Java Platform, Standard Edition)

Hi everyone,

I've been puzzling over this one for a while now, hopefully someone knows what to do.

I'm upgrading my application to use JRE 1_3_1_01 instead of 1_3_0_01. I made the changes, installed the new plug in and it all works fine, except for one thing.

The problem came up when I started testing whether my web page would re-direct the users to install the newer version of the plug-in (because they presently have the older version installed in their machines) when it's not installed. However, that didn't work.

For Internet Explorer, when I bring up my web page (which indicates the use of the 1_3_1_01 plug-in), the browser simply uses the old version instead of attempting to install the newer version.

For Netscape, the browser simply doesn't show anything (no error message, nothing).

DOes anybody have a clue what the problem is? I don't see this problem when I uninstall ALL versions of the plug in and go to the page in question (in this case everything works as it should), but the likeliest case is that my users will have the older version of the plug-in installed.

I have looked into "plug-in detection", but that would only work somewhat with netscape (the plugin array is populated) and there is a not-so-pretty solution for detecting plugins in IE (involves having to know the ActiveX class ID of the JRE)

Any help will be appreciated.
