I am updating a ~10 years old java GWT project. I replaced old eclipselink version to eclipselink 4.0.2 (comes with jakarta). It compiles but when I start it in Eclipse java.lang.ClassNotFoundException: javax.sql.DataSource pops up.
I tried to google it but no luck so far, can't see the proper jar file to download, however, I feel this can be a simple problem.
This project is an Ant project, not a Maven one.

Check the version of java which was used to compile with the version being used a runtime. Is the runtime version old? This would explain why it doesn't have this class/interface
