Java not working on my browers

[cyberchimp]

For some reason some java has stopped working on my PC. No java at all (scripts or applets) work with Opera anymore, and though most scripts run when I view them with IE and NN, some applets don't (eg the World Keyboard launcher at Babel Fish: http://babelfish.altavista.com/). I get the java coffee cup icon in my sys tray, and as a 'place-holder' where the java applet should be, but nothing executes. I have the java plug-in listed three separate times in my Control Panel (v1.3.1, v1.4.0 and v1.4.1) - could this be causing the problem? Anyone got any ideas how I get java working consistently on my browsers again?

I think this can be caused by the JRE (Java Runtime Environment)conflict,YOu need to find out that out which version is causing this conflict and remove that from your system

Many thanks for this, Khalid Ali. Do you know how I would go about determining which of these three versions is causing a JRE conflict? (I am reluctant to randomly uninstall any of the versions, in case this makes the problem worse!)

Anyone?

at the dos prompt you can type the folowing to to find out which sdk and jre is configured on your machine
for JRE

C:\>jre -version


and for java sdk

C:\>java -version

Erm...sorry but I'm not sure how to do this. If I open

Start > Programs > Accessories > MS-DOS Prompt

Then I get

C:\WINDOWS>

How do I just get the C:\ prompt (without the WINDOWS bit)?
(I'm using Windows ME if that makes any difference.)
Thanks.
