Migration to flex 3.3

Question

Hi,
I am migrating a project from Flex 2.0.1 to Flex 3.3 (very behind I know - should I go straight to Flex 4?).
Anyway, I installed the Flex 3.3 SDK, including the data visualisation components, recompiled the application and all ran fine, using LCDS 2.5.1 and JRUN 4. (I am not using Flex Builder).
Then I added references to AdvancedDataGrid in ActionScript code in my application and tried to recompile. These references were undefined. What else do I have to download and install to be able to use the Advanced DataGrid in ActionScript?
I tried to install LCDS 2.6.1 with Tomcat, but there didn't seem to be an option to run it with JRUN 4 and my application will not run with it at present.
I am confused. Can anyone help please?
Thanks.
Annette

Hi,
Thx Alex for your help and quick reply, I think I have found the problem in my project. Actually we are using swfobject in our index.jsp to call my .swf file.
We are using parameter when we called our .swf from Tomcat :
     /app/flex/app.swf?server=http://localhost:8080/app&flexroot=/flex&lang=en_US&jre=1.6.0.11&flashVersion=10.0.32
It's working in Flex2, but when we're using Flex3 it caused "VerifyError: Error #1014: Class mx.core::Application could not be found". My colleage said this is URLEncode problem and I have to replace '/' with '%2F'  and ':' with '%3A'. So we have to use syntax like :
     /app/flex/app.swf?server=http%3A%2F%2Flocalhost%3A8080%2Fapp&flexroot=%2Fflex&lang=en_US& jre=1.6.0.11&flashVersion=10.0.32
The strange thing is, why it's working in Flex2.. Thanks again for your help
