HI Team ,

I am retrieving value from database through JDBC statement  my plsql query is below -

Select * from A union Select * from B.

but when i am retrieving value through JDBC statements its give null . when i am individually running query like Select * from A without using Union  its working fine and giving results but when i am using 2 query via Union its give Null. Please tell me where i m wrong .

I am rewrite an java app. The original is a jar file.  In the project it is calling http URL connections. Do I need to  generate a dynamic web project or just a simple java project?

Thanks

Hi,
Since I'm making a board game engine..

For a phone game, wouldn't dragging and dropping chess pieces, for example, be infuriatingly uncertain / complicated for players on a smaller phone screen?
If only legal moves are considered playable, what is best for a game like this? what is the current expected / standard?

thanks

Hi
Considering my other game-server question, a rep from Amazon called me a little while back and said the server I had acquired for my project is being unused. I accepted an upgrade deal for it. - anticipating my awesomeness.
(This is the one I got before I became interested in playerIO.com as a game server.)
It is a bare metal dedicated server, I think, on its own, that's what she said, and I read that recently that that is faster/more reliable  than cloud servers.
Should I let playerIO out to pasture and do the entire job myself on my dedicated? Luckily, I haven't committed any money to the other.
playerIO servers must be written in C, not Java, (only clients can be in Java) and based on the ridicule, and spiteful comments I've received for wanting to do a server in Java ;D is that a hint!?
Why is minecraft java okay, then?
Does playerIO seem practical?

Thanks again for the time.
