Tom,

I'm not sure if you have seen the Getting Started page on the Dali 
website, but here is a link - 
http://www.eclipse.org/webtools/dali/gettingstarted.php.

Did you have a previous version of Dali installed before installing 2.1?  
If not, then the Dali plugins appear to be in your installation.

Make sure you also have WTP 3.0.3 Java EE Developer Tools installed.  This 
was probably installed while installing Dali 2.1, but just to be safe, try 
to install/update the Java EE Developer tools to version 3.0.3.

Library management is something we are working on for Dali 2.2, but for 
now, all you need to do is define a User Library with the necessary 
javax.persistence and EclipseLink classes.  This can be done using the 
JARs included in the main Eclipse download, or you could add all the 
necessary bundles to the library.  

The main download JAR's to include are:
../jlib/eclipselink.jar
../jlib/jpa/javax.persistence_1.0.0.jar.

For bundles, you would need the following:

javax.persistence_1.99.0.jar
org.eclipse.persistence.jpa_1.0.2.jar
org.eclipse.persistence.antlr_1.0.2.jar
org.eclipse.persistence.asm_1.0.2.jar
org.eclipse.persistence.core_1.0.2.jar


Hope this helps,
Neil
