hi Hariharan Anantharaman, Didier Durand & Jonathan He * * *Thanks for the clue, i've resolved this issue.* *I'm using IntelliJ actually.* *Yeah it needs extra configuration to get rid of this issue.* * * *It is nothing todo with entity class.* * * *I think the main reason is, why don't they create a simple batch/shell script file to do this?* *I look at GAE SDK 1.3.4, actually they did this through their Ant's build.xml, but unfortunately am using Maven to automate building process which GAE didn't support it yet at a moment.* *It really helps if they just provide a simple independent batch/shell script file for this.* * * *This is what i found so far.* *If you are guys are keen to know how to solve this issue within IntelliJ, do PM me.* *I will be glad to help you out.* * * *Thanks,* *Marthen* * * * * * * On Fri, Jul 2, 2010 at 9:57 PM, Jonathan He <[email protected]> wrote:
