Errors in Jdev Trying to Run jsp

Question

I have a project with 3 files.
a jsp file that only does ui
a connection class that attempts to create a connection
a service class that uses above connection to try to get data.
I would like to eventually store the password and connection information on an IAS 904 install in
$ORACLE_HOME/j2ee/wds/config/data-sources.xml
and
$ORACLE_HOME/j2ee/wds/config/jazn-data.xml
So I want to use password obfuscation.
without using wizards, and directly editing config files, is there a way to set this up? I've tried editing the D:\Program Files\Oracle\jdev904\j2ee\home\config\data-sources.xml
and
D:\Program Files\Oracle\jdev904\jdev\system9.0.4.0.1419\oc4j-config\data-sources.xml
on my local drive, but when I try to run my jsp file, I get the following error:
oracle.jdeveloper.deploy.DeployException at oracle.jdeveloper.deploy.oc4j.ds.Oc4jDataSourcesNode.syncWithConnectionManager(Oc4jDataSourcesNode.java:68)
when I run my connection class, I get:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
Here's my code:
ublic static Connection getConn() throws Exception
String JNDINAME="jdbc/pool/OracleCache";
Context ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup(JNDINAME);
Connection conn = ds.getConnection();
conn.setAutoCommit(false);
return conn;
Here is my data-source entry:
<data-source class="oracle.jdbc.pool.OracleConnectionCacheImpl" name="OracleDS" location="jdbc/pool/OracleCache" connection-driver="oracle.jdbc.driver.OracleDriver" username="scott" password="tiger" url="jdbc:oracle:thin:@host:1521:sid" inactivity-timeout="30" min-connections="3" max-connections="3"><property name="cacheScheme" value="1"/></data-source>
Do I need to specify anythign else? I don't do any other special configurations. And I'm not very keen on the wizards.
I'm running 9040.

In jdev there is the Connections tab-page (like run manager or applications); to get your data you can use java code but you also can make a connection to database using wizard :d. It's very simple to get data from tables this way... (there is here a problem: using java code it's possible to gain performace in your application...i'm not so sure).
Also, you can watch the demos/sample_code from Oracle: (http://www.oracle.com/technology/products/jdev/viewlets/viewlet.html
and here:
http://www.oracle.com/technology/sample_code/products/jdev/index.html); those demos are very good.
