Error Connecting to Database using Weblogic Datasource

Question

Hi,
I am trying to connect to oracle database from my program using weblogic DataSource. I am using JDK1.3.1.08 , weblogic 7.
I am using the following code to get Connection object.
contextFactory ="weblogic.jndi.WLInitialContextFactory";
providerURL="t3://192.168.0.29:7001";
dataSource ="temp_ds";
if(contextFactory!=null)
properties.put(Context.INITIAL_CONTEXT_FACTORY,contextFactory);
if(providerURL !=null)
properties.put(Context.PROVIDER_URL, providerURL);
initCtx = new InitialContext(properties);
DataSource ds= (javax.sql.DataSource) initCtx.lookup(dataSource);
Connection con = ds.getConnection();
con.setAutoCommit(false);
I am getting the following error while running the program. Can any body help?
javax.naming.CommunicationException. Root exception is weblogic.socket.Unrecove
rableConnectException: [JDK 1.3 or higher required]

Answer 1

I am not sure if this is the reason, but going thru the stack trace ...
javax.naming.CommunicationException. Root exception is weblogic.socket.Unrecove
rableConnectException: [JDK 1.3 or higher required]Make sure you have JDK 1.3 or higher installed.
