another Quote:
In a JDK 1.0.2 based Web Browser, like Netscape 3.0, an applet can only open sockets to the host from which it was downloaded. For Oracle7 this means that the applet can only
connect to a database running on the same host as the web server. Now, when I look at the docs, to connect from an applet to a local DB(Web-machine = DB-machine) I need to
give a connectstring
like:("jdbc:oracle:thin:scott/tiger_at_www-aurora.us.oracle.com:1521:rdbms3") Why do they need LISTENER parameters, when connecting to a LOCAL DB ? How the !@^$%##@ do I make this connection ? ("jdbc:oracle:thin:scott/tiger_at_www-aurora.us.oracle.com:1521:rdbms3") -- no such file or directory (eh ?)

("jdbc:oracle:thin:scott/tiger_at_ORCL)                                  --
security exception
("jdbc:oracle:thin:scott/tiger_at_www-aurora.us.oracle.com")             --

null
Using Webserver 2.1, NS3 and PO7.
Anyone ?
