HI All,

How do i set the JNDI Data source name in tomcat?

my System DSN name is "someDSN" and my code to return the Datasource is as below(DataSource.java),

private String dsName=null;

public DSLogin(String dsName){
public DataSource getDataSource() {

try {

Context ctx = new InitialContext();
dataSource = (DataSource) ctx.lookup("java:comp/env/"+dsName);
catch (NamingException ex) {
System.out.println("DataSource: ");ex.printStackTrace();
return dataSource;

I am calling the above method as follows,
DataSource dataSource = new DataSource("someDSN");

I am getting javax.naming.NameNotFound Exception.

Any pointers will be helpful.

Hi Such,

What driver are you using? Is it jdbcodbdriver? Try doing it like this and update us if you find any luck:

javax.naming.Context ctx= new javax.naming.InitialContext( );
javax.sql.DataSource ds = ctx.lookup("java:comp/env/jdbc/"+dsn);
java.sql.Connection conn = ds.getConnection( );

It is sorta covered in the JavaRanch Style Guide.
