Deployment of Jdeveloper 11g application on WLS 10.3   Dec 17, 2009

While testing a simple deployment on WLS, things more or less went as expected, and the deployment ended up successful.  However, we hit a problem when the application was ran due to the fact that we were using URL based JDBC.  Even though one could get around the problem by defining JDBC Data Source, but i was curious to know why the WebLogic application server kept giving us the following error when using URL based JDBC connection

oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection.

at oracle.jbo.server.ConnectionPool.instantiateResource(

Truncated. see log file for complete stacktrace
java.sql.SQLException: ORA-01005: null password given; logon denied

The solution lies in setting  in the JAVA_PROPERTIES entry of  ( I am running Linux)

The file can be found   the following subdirctory structure under the WLS home

user_projects/domains/AMMAR_REALSOFT/bin    (where AMMAR_REALSOFT was my testing domain name)

below shows what exactly was inserted in the file
