JDBC Datasource connection failure from WAS6.0
558024Jan 24 2007 — edited Jan 24 2007I am using Websphere Application Server 6.0 and trying to create a JDBC Datasource (Connection Pool flavor) to connect to Oracle 10g Express. I have supplied what I THINK is the correct URL (guessing at the port and service) and credentials (verified through SQL Plus). I am getting an error message. All details are below. Please advise:
Oracle version information:
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Product
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
Data store helper: Oracle 10g data store helper
URL: jdbc:oracle:thin:@//localhost:1521/XE (I assumed the default port, and service=XE from the Oracle admin web console parameters)
JAR file: ojdbc14.jar, referenced by WAS in Oracle 10g installation directory.
Error:
