I have a Dell 4550 running XP , 512MBRAM:2.4 GHZ PC Desktop. I recently downloaded netbeans 5.0, it worked for a bit but then I was confronted with the following error message displayed in a single window dialog: "java.lang.noClassDefFoundError Exception occurred ... "

Does the mentioned file exists in you JDK installation and can be read? If not, you'll probably have to reinstall JDK.
Reporter, did you start with new userdir or reused the old one ?
demirelli, it looks like your JDK installation got corrupted somehow, exception says that there are some problems with reading C:\Program Files\Java\JDK1.5.0_04\jre\lib\flavormap.properties, which means that DnD can't be initialized properly and causes problems in NetBeans (and in other java apps as well I think). Please reinstall your JDK and problem should be solved, thanks.
