I made the code as follows Context ctx = null; Hashtable ht = new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); ctx = new InitialContext(ht); System.out.println(ctx.getEnvironment()); ds = (javax.sql.DataSource) ctx.lookup ("JdbcDataSource"); con = ds.getConnection(); I get the error as java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructor   More>>

I made the code as follows

Context ctx = null;

Hashtable ht = new Hashtable();

ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");

ht.put(Context.PROVIDER_URL,"t3://localhost:7001");


ctx = new InitialContext(ht);

System.out.println(ctx.getEnvironment());

ds = (javax.sql.DataSource) ctx.lookup ("JdbcDataSource");

con = ds.getConnection();


I get the error as
