Invalid Oracle URL specified connecting to 8.1.7

You must use a valid IP and port number

I have a valid Id and Port. I blanked them out to prevent from public view.

I don't think you need to blank the port ;-) Please post again with it looking at bit more realistic

You should be able to use the machine name too. Let's say the Oracle server machine is called 'ray' and you can do

ping ray

Then you should be able to use

jdbc:oracle:thin@ray:nnnn

where 'nnnn' is the right port number

Below is the exception thrown. I have 2 drivers I have tried this with.-- classes12_g.zip and ojdbc14.jar --
My classpath is:/i2k/rxs/java/j2sdk1.4.2/lib:/i2k/rxs/java/j2sdk1.4.2/drivers/classes12_g.zip:.

I resolved this issue by adding a ':' between the thin and @.  
jdbc:oracle:thin:@")

Thanks for youe help

OK :-)
