The system performs the following actions on the dictionary tables referenced by the SQLJ database during a CALL statement that executes a Java external procedure:
  1. Validates the Java procedure to be called.
  2. Retrieves the row matching the Java procedure name from the DBC.Routine_Jar_Usage table to determine which JAR must be loaded to execute this Java procedure.
  3. Verifies that the JAR named in DBC.Routine_Jar_Usage exists by finding the corresponding row in the DBC.Jars table.
  4. Retrieves any rows from the DBC.Jar_Jar_Usage table that indicate whether this JAR includes other JARs, and makes sure those JARs are also loaded.
