Question : What does java.lang.NoClassDefFoundE<wbr />rror: mean

I am trying to run a Java Application on WSAD 5.1.2 and when my app starts I receive this error

Error --> java.lang.NoClassDefFoundError: java/util/LinkedHashMap


Any suggestions.

Thanks in advance. Annie

Answer : What does java.lang.NoClassDefFoundE<wbr />rror: mean

Which java version are you using here? LinkedHashMap has got added in java4. So, if you are using java 3 or below you will get this error message.
