It is common in a Java class declaration to include an import statement to access classes in another package. You can reference imported classes using unqualified class names.
For example, you can reference the Stack class of the java.util package in two ways:
explicitly using the name java.util.Stack
using the name Stack, and including the following import statement:
A class referenced by another class, either explicitly with a fully qualified name or implicitly using an import statement, must also be installed in the database.
The import statement works as intended within compiled classes. However, within the SQL Anywhere runtime environment, no equivalent to the import statement exists. All class names used in stored procedures must be fully qualified. For example, to create a variable of type String, you would reference the class using the fully qualified name: java.lang.String.
