Hi all,

   I appreciate if anyone could help me out with my issue. I wrote simple java code on win 2000 to test whether I will be able to access Oracle 8i DB resided at some xxx.xxx.xxx.xxx machine within the network.

The code is:

---------------------------------------
  DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
  Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@111.111.11.11:1526:DBinstance","user","password");
---------------------------------------

The fist line here is executing and the problem is with second line of code. After executing this application from my DOS window, I am getting error:

java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
        at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:169)
        at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:211)
        at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:324)
        at oracle.jdbc.driver.OracleConnection.<init>(OracleConnection.java:266)
        at oracle.jdbc.driver.OracleDriver.getConnectionInstance(OracleDriver.java:365)
        at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:260)
        at java.sql.DriverManager.getConnection(Unknown Source)
        at java.sql.DriverManager.getConnection(Unknown Source)
        at DBConn.getConn(DBConn.java:15)
        at DBConn.main(DBConn.java:40)

I have installed Oracle client, where I can access the same database using SQL * Plus, but why I am unable to access the database from a Java Application? Do I need any web/application server to access it?

Thanks,
cs

Isn't the default oracle port 1521?  Did you change it on purpose?
