# Migrating Proprietary Extensions

A number of classes proprietary to the Application Server 6.x environment might have been used in applications. Some of the proprietary packages used by Application Server 6.x are listed below:

- `com.iplanet.server.servlet.extension`

- `com.kivasoft.dlm`

- `com.iplanetiplanet.server.jdbc`

- `com.kivasoft.util`

- `com.netscape.server.servlet.extension`

- `com.kivasoft`

- `com.netscape.server`

These APIs are not supported in the Application Server. Applications using any classes belonging to the above package must be rewritten to use standard J2EE APIs. Applications using custom JSP tags and UIF framework also need to be rewritten to use standard J2EE APIs.

For a sample migration walkthrough using the iBank application, see Chapter 7, Migrating a Sample Application - an Overview.
