When creating and deploying Java Stored Procedures and Java User-defined Functions, make sure the JAR name consists of the following valid characters:
- Uppercase or lowercase letters (A to Z, a to z)
- Digits (0 through 9)
- Special characters: dollar sign ($), number sign (#), low line (_), dot (.), and hyphen (-).
The JAR Name cannot be “RETURNS” or contain KANJI characters.
