Compile application on serverside

Hi,

I have installed Tomcat 5.5 and LCDS

Copied lcds.war in the webapps folder

When I create a flex project and say compile at server side the application is giving me 2 errors :(
1046: Type was not found or was not a compile-time constant: Session.
And
Server SDK: Directory does not contain a Flex SDK.

Any idea :eek:
In some web page I could find that it is solved using changing the Flex version in the flex compiler in the properties of the prject. But this is not applicable for me since this is compile at server side the application

Thanks in Advance
It will be of gr8 help for me

Better do it locally and then upload.
