Muthu, 1) If you declare id in your POJO you will consume memory twice, because id is already a key that will be used to put into cache. Do you really need this?
2) Actually you could do this with web console, but a bit tricky... Go to "Summary screen" -> Scroll down to "Client" section -> Click on "POJO" tab -> check "Include key fields" check box -> click "Download" POJOs will be generated with key fields.
