What is the difference between being a Java EE licensee and being Java EE compatible?
A Java EE licensee has signed a commercial distribution license for Java EE. That means the licensee has access to the compatibility tests and has made a commitment to maintain compatibility. It does not mean the licensee’s products are necessarily compatible. Look for the Java EE brand which signifies that the specific branded product has passed the Compatibility Test Suite (CTS) and is compatible.
