Create a new Java package and a new Java Class under the Java project titled Starthis which you created in Section 5.3, “Setting-up Eclipse 3.0.2”. You can name your Java package and Java class according to your preference. This document names the Java class as ClgxCreator.java.

Copy-paste the following code fragment into ClgxCreator.java. If you chose a different name for your Java class, make sure that you edit the code fragment below to reflect the same.

 * EXAMPLE:
 * Create a new Entry for a PLC in the database.
 * Use the Admin session bean. It supports the creation of a
 * PLC bean identified by its EtherNet/IP path (EPATH).
 * Also ensure that all of the data tag names and their
 * corresponding types are read from the PLC and stored in
 * the database.
