Using oracle conn. manager - connection refused

[deb platt]

Instead of using RMI to connect an applet to a remote database, my dba installed Oracle Connection Manager on the web host, and I am now trying to connect to it from the applet as described at Cman.

Here is my connection string:

  
String conStr = "jdbc :-o	 racle:thin:@(description=(address_list=" +
"(address=(protocol=tcp)(port=1600)(host=webhost.mydomain.com))" +
"(address=(protocol=tcp)(port=1525)(host=dbhost.mydomain.com)))" +
"(connect_data=(sid=testdb))" +
"(source_route=yes))"; 

Where webhost, dbhost, mydomain have been replaced with values specific to my company.

When ever the applet attempts to connect to the database, I get a

 Connection refused   

error, with error code 12504. As I understand it, this error code means that I didn't supply the sid as part of my connection string.

According to the oracle documentation on the configuration syntax, it's this:

  
CMAN_RULES=
 (RULE_LIST=
   (RULE=
    (SRC=host)
    (DST=host)
    (SRV=service_name|sid)
    (ACT=accept|reject))
    [(RULE= ...)])

For the SRV parameter, it goes on to say:

SRV: Specify database service name of the Oracle9i or Oracle8i database... or Oracle System Identifier (SID) value of the pre-release 8.1 database

We are using Oracle8i, so we specified the service name. Our service name is the name of the webhost followed by a hyphen followed by the sid, so webhost-testdb. In addition to the connection string above, I have also tried the following connect_data values:

"... (connect_data=(sid=webhost-testdb))" + ...
"... (connect_data=(instance_name=webhost-testdb))" + ...

Any suggestions would be appreciated.
