    Java in the database Q & A

What can I not do with Java in the database?

Adaptive Server Anywhere is a runtime environment for Java classes, not a Java development environment.

You cannot carry out the following tasks in the database:

• Edit class source files (*.java files).

• Compile Java class source files (*.java files).

• Execute unsupported Java APIs, such as applet and visual classes.

• Execute Java methods that require the execution of native methods. All user classes installed into the database must be 100% Java.

The Java classes used in Adaptive Server Anywhere must be written and compiled using a Java application development tool, and then installed into a database for use, testing, and debugging.
