Oracle Connectivity with thin drivers

[shams sh]

I want to make a Database Connection to Personal oracle 8 using thin driver classes12.zip I am using windows98 and personal oracle. It compiles properly but when I run it i get the following SQL error :
"error My Own Sql error:IO exception:The network Adapter cannot establish the connection ".
I havent made a SID in my oracle. Is a SID important?
