IPv6-only Clients Cannot Connect to the Application Server (4742559)

If IPv6 is not used in your network, this problem does not apply to you.

By default, the Sun ONE Application Server 7 instances and Admin Server instances use IPv4. IPv4 is supported by all system software on which the Sun ONE Application Server is available. The Sun ONE Application Server configuration changes are required for conformance on those platforms where IPv6 is supported.

If these configuration changes are to be made, you must be absolutely sure of IPv6 support. If the IPv6 related configuration is applied to a system that has only IPv4 support, Application Server instances might not start.

Workaround: Perform the following configuration changes:

1. Start the Admin Server.

2. Start the Admin Console by connecting to the Admin Server HTTP host or port in a browser.

3. Select the server instance to configure for IPv6, for example, server1.

4. Expand the HTTP Listeners node in the tree view.

5. Select the HTTP Listener to configure for IPv6, for example, http-listener1.

6. Change the value of the IP Address field to ANY in the General section.

7. In the Advanced section, change the value of the Family field to INET6.

   If you set the Family field to INET6 IPv4, functionality is not disabled unless an IPv6 address is selected for IP address. Selection of an IP address of ANY matches any IPv4 or IPv6 address.

8. Click Save.

9. Select your server instance from the left pane.

10. Click Apply Changes.

11. Click Stop.

12. Click Start.

    The server restarts and implements your changes.
