I try to run the examples in J2EE Tutorial. When I run Converter example, it works well in IE5.0 but in client application, it always says: Apllication threw an exception:java.lang.NoClassDefFoundError: ConverterHome. I check in the deploytool, i indeed put the class in. The same situation happens when I run SavingsAccount examples and some others in command window. What's the problem?
