Hello,
I am able to connect to my database from a stand alone java program, however
the same connection information throws an exception when used via JNDI.
My stand alone app:
import java.sql.* ; // for standard JDBC programs
public class TestCon {
public static final String DBDRIVER = "oracle.jdbc.OracleDriver" ;
public static final String DBURL = "jdbc:oracle:thin:@(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abc-def-scan.corp.xyz.com)(PORT = 1521))
(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = SAMPLE.WORLD) ) )";
public static final String DBUSER = "user1" ;
public static final String DBPASS = "pass1" ;
/**
* @param args
*/
public static void main(String[] args) {
Connection conn = null ; // DB CONNECTIONS
PreparedStatement pstmt = null ;// DB OPERATIONS
ResultSet rs = null ; // save the query result
try {
Class.forName(DBDRIVER) ;
conn = DriverManager.getConnection(DBURL,DBUSER,DBPASS)
;
String sql = "select abc from xyz" ; //sample query
Statement stmt = conn.createStatement() ; // execute
the query and save
the result
rs = stmt.executeQuery(sql);
rs.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} // Load the ORACLE DRIVER
catch(SQLException sql)
{
// TODO Auto-generated catch block
sql.printStackTrace();
}
}
}
MY JNDI / Context.xml configuration
<Resource name="jdbc/myoracle" auth="Container"
type="javax.sql.DataSource"
description="Oracle Datasource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=abc-def-scan.corp.xyz.com)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=SAMPLE.WORLD)))"
username="user1" password="pass1" maxActive="20" maxIdle="10" maxWait="-1"
validationQuery = "SELECT 1 FROM DUAL" />
The error I get when trying to run the following code from a servlet:
try {
Context initContext = new InitialContext();
Context envContext = (Context)
initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)
envContext.lookup("jdbc/myoracle");
Connection conn = ds.getConnection();
conn.close();
conn = null;
}

The query runs fine when used in a stand alone java app, and I have tried
all things in the Context.XML to resolve.
I know it connects fine to the DB, however the getConnection from the JNDI
datasource is causing that error to be thrown.
