Hi Amey,

You'll likely want to verify your settings. Make sure the registry settings are being picked up.

Hi Jeremy

I have carried out the steps but it still seems to give the error.

Thanks for the response.

Are you getting this error only when trying to access the System Information section? Also, do you have enough physical memory to allocate to Tomcat (assuming that you're using an EAR-WAR version)?

Please also be sure to restart tomcat once you increase the memory. =)
