IDE ProblemsThis section addresses the following problems:
Application Server is not in the Sun ONE Studio Server Registry.
I start the Application server 7 with the command line asadmin start-appserv and everything seems to work fine. I can log on to the Administration interface using http://localhost:4848/admin and see that the server1 instance has started and exists. I go back to the runtime tab in Sun ONE Studio and the Server Registry has no entry for the Sun ONE Application Server. Do I need to refresh the Server Registry or the Installed servers underneath?
Is the Application Server plug-in for Sun ONE Studio installed?
If not, you can get it from update center if you have Enterprise Edition of Studio. Make sure that you have registered for the product.
Is the plug-in configured with the Application Server installation directory?
- In the IDE, bring up the Explorer window and Runtime tab at the bottom of this window.
- Expand the Server Registry, Installed Servers, and Sun ONE Application Server7 nodes.
- Right-click the Sun ONE Application Server 7 node and select Properties.
The properties editor is displayed.
- Ensure that the Sun ONE Application Server Server Home property is configured with the location of either the Application Server or Application Server's administrative client component.
Is the Application Server registered?
- Under Installed Servers, expand the Sun ONE Application Server 7 node.
If you see a localhost node under the Sun ONE Application Server 7 node, an Application Server instance is already registered.
- If you either do not see a registered Application Server, or the registered server is not the server of interest, right-click the Sun ONE Application Server 7 node and choose Add Admin Server.
The Add Admin Server dialog box appears.
