I am currently developing Java applets/applications using JDK 1.2.1, Oracle 8, and Windows NT 4.0 Service Pack 3. Sometimes my application can connect to my Oracle database, however, most of the time I get this error:

java.sql.SQLException: The Network Adapter could not establish the connection

Does anybody know why sometimes I can get a connection and other times I can not. Thanks. Received on Mon Jun 28 1999 - 18:05:41 CDT
