addition to i found the only rows shows posttime that i added yesterday,but i added rows now,it can't show at all!these errors are showing when i edit new rows.

johnsysq,
I was unable to reproduce this error at my end. Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Are you running it the way that has been specified in the ReadMe doc ?

hello,nipun supporter!
first,thanks a lot for your reply!
the project is done well!the reason of error is my database structure configuration!the posttime is defined by 'timestamp'!i want to ask you how to configure the 'posttime' and is it a 'varchar'?

You should check the database documentation to get an answer to this. Im not sure. Sorry about that.
