Standalone java class

Question

hi, i have written a java file that works fine when i run it with a jsp file in weblogic. now i need to extract the class file as a standalone to run in a batch file. i got the following error:
Exception in thread "main" javax.naming.NoInitialContextException: Need to spec
fy class name in environment or system property, or as an applet parameter, or
n an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
at myw_batch.Schedule.<init>(Schedule.java:72)
at test.main(test.java:11)
my database connection is as follow in my code:
ctx = new InitialContext();
ds = (DataSource)ctx.lookup("mydatasource");
con = ds.getConnection();
since my db data source is configured at the weblogic end, so will my standalone be able to reuse the data source? thks in advance.

Like it says, you
"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"
You can find out about it here: http://java.sun.com/products/jndi/tutorial/beyond/env/source.html
These are the default settings for weblogic.
You probably need these in a jndi.properties file
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://127.0.0.1:7001alternative is to try something like this:
Map env= new HashMap();
params.put("java.naming.factory.initial", "weblogic.jndi.WLInitialContextFactory");
params.put("java.naming.provider.url", "t3://127.0.0.1:7001");
ctx = new InitialContext(env);
