Urgent! Cannot run java programme. Pls help!

1st question:

I am using JDK 1.3.1_03 on Win2K Server. When I have compiled the java applications, I try to use

"java <application name>" to run the programme, but an error message "Error occurred during initialization of VM

java/lang/NoClassDefFoundError: java/lang/Object" come up on the screen. Why is it so? It run normally in the past.

I have upgraded Windows2K once using the Win2K Server CD recently, is it the cause of the problem?

How can I solve it? Please help! Thank you!

2nd question:

I have installed JDK1.4 Final version recently. However, after I have uninstalled it, it still appear in the Add/Remove Programme list in the control panel. I have tried to install another version of JDK, see if it would replace the JDK1.4,

but it failed. Why is it so? Now when I go to some websites designed by javascript, the Internet Explorer suddenly closed by itself. How can I solve the problem? Please help! Thank you!
