Where is AlphaState?

I think I may have done something very wrong with setting up JMonkey. I tried compiling several examples, and many of them couldn't find AlphaState. It's not in the JME2.0 jar, either. I understand that an alternate way to get the source code is the whole ant/CVS compiling process, but I just downloaded the jars. Then I tell my IDE (I use BlueJ, because of it's simplicity) to use the JME_2.0.jar as an extension. What am I doing wrong?

Thanks for any help.

AlphaState has been changed to BlendState, check the changelog http://www.jmonkeyengine.com/wiki/doku.php?id=jme_to_jme2_changes.
