Updating classes and JAR files

You can update classes and JAR files using Sybase Central or by executing an INSTALL JAVA statement from Interactive SQL or some other client application.

To update a class or JAR, you must have DBA authority and a newer version of the compiled class file or JAR file available in a file on disk.

When updated classes take effect

Only new connections established after installing the class, or that use the class for the first time after installing the class, use the new definition. Once the Java VM loads a class definition, it stays in memory until the connection closes.

If you have been using a Java class or objects based on a class in the current connection, you need to disconnect and reconnect to use the new class definition.
