Use of OracleDataSource in Jdeveloper ok, but fails in HotSpot Java VM

Question

I'm using JDeveloper Studio Edition Version 11.1.2.0.0 to make an application that uses OracleDataSource for hooking up to an Oracle DB (11gR2).
JDeveloper uses the bundled WebLogic server when running apps in the developement environment. When configuring my project to use JDBC for the database connection I simply included the "Oracle JDBC" package. In my setup, being a default install, this creates classpath entries that refers to ojdbc6.jar that sits deep in the WebLogic file structure;
C:\Oracle\Middleware\jdeveloper\ide\macros\..\..\..\wlserver_10.3\server\lib\ojdbc6.jar
C:\Oracle\Middleware\jdeveloper\ide\macros\..\..\..\oracle_common\modules\oracle.nlsrtl_11.1.0\orai18n.jar
C:\Oracle\Middleware\oracle_common\modules\oracle.odl_11.1.1\ojdl.jar
C:\Oracle\Middleware\oracle_common\modules\oracle.dms_11.1.1\dms.jar
When running my code in the JDeveloper environment it works flawlessly.
The application will only be run intermittently in the free and it was hoped that we could avoid the need for a dedicated app-server for it to run in, thus I'm trying to get the app to work with a default Java HotSpot client installation on a Windows 7 workstation. This seems to be rather problematic as it refuses to locate the OracleDataSource class even though I'm throwing all sorts of classpath variations into the mix. I've even tried running it with different versions of Java without any luck.
My code looks like this:
try {
OracleDataSource ads = new OracleDataSource();
// Create a connection to the database
String serverName = properties.getProperty("oradb.servername");
String portNumber = properties.getProperty("oradb.portnumer");
String sid = properties.getProperty("oradb.sid");
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
ads.setURL(url);
String username = properties.getProperty("oradb.uid");
String password = properties.getProperty("oradb.pwd");
dbConn = ads.getConnection(username, password);
} catch (SQLException e) {
e.printStackTrace();
// Could not connect to the database
When attempting to execute with the HotSpot VM my application consistently fails in the "OracleDataSource ads = new OracleDataSource();" line
with the error message: "Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdbc/pool/OracleDataSource".
I'm using the JDeveloper's deploy functionality to generate a Client JAR or a simple JAR.
All indications are that the desired JDBC-functionaly is found in the ojdbc6.jar library, but it seems that it simply isn't enough to include a proper path to this library in the classpath when executing the application outside of the JDeveloper environment.
Anyone have a clue as to what I'm missing here??

When specifiying a Deployment Profile in JDev one have to specify which appserver that will be used, but the default choice is <None> which translates into a deployment bundle (Jar-file) for use with your computers standard JRE.
I don't use the IDE but I can only hope that when you do that it means that it no longer has anything to do with an JEE server, including weblogic. Thus that is not relevant to your solution nor the problem.
I've tried to find a way to make JDeveloper bundle the drivers similarly. When configuring a Deployment Profile in JDev there are check-boxes that would indicate that the libs would be included in the resulting JAR-file, but it doesn't work that way in practice. Unfortunately!Seems rather unlikely that an IDE that expects to do JEE wouldn't allow the correct solution in some way. But maybe it expects the driver to be installed into the JEE server rather than bundled. There might be a way to explicitly specify a manifest file. Of course you would need to manually create it first.
