javax.persistence.* not found

Hi

I have a problem compiling bookstore1 sample in the j2ee tutorial. Below is the error message:

Compiling 11 source files to D:\Experiment\JEE\javaeetutorial5\examples\web\bookstore\build\classes

I have tried to add toplink library, and populate the database, but still fail to build successfully. Any help appreciated.

Cheers

I had the same error when using JBoss as server in Netbeans.
If using Glassfish server I didn't get the error.

Hi

It works now. I read this solution on a forum:


It seems that "bookstore1" project (web application), is importing the "dist/bookstore.jar" from another project (persistence unit?). In this case, NetBeans will also try to recompile the project's dependencies (other projects that may also require "TopLink Essential" library in the compiler's CLASSPATH).

I think you should open the other project (manually or right click the web project, and select "open required projects" option), and edit its properties to also add the "TopLink Essentials" library to the compile-time libraries (in the "libraries" category).

Cheers
