[birt-dev] can't find IQueryResults class in birt-runtime-2.1RC1a.zip

["Chaohua Wang" <chaohua.wang@xxxxxxxxxxxxxxx>]

Hi, Folks,

 

When I compile the following code,  There is no these  IQueryResults, IBaseExpression, and IResultIterator classes files with birt-runtime-2.1RC1a.zip.

It compiled in birt-runtime-2_0_1.zip. I think it is in package import org.eclipse.birt.data.engine.api.*;

But I can’t find it in birt-runtime-2.1RC1a.zip.

 

Please let me know where I can find the jar files contains IQueryResults, IBaseExpression, and IResultIterato class in with birt-runtime-2.1RC1a.zip.

 

Thank you very much
