    How can I test the connections between a JDBC thin client and database?

    Is there a simple test to test the connections between a JDBC thin client to the database (on a database server). Because there is no Oracle Client on the Client PC, I can't use tnsping or sqlplus to test the connection. How to I test this connection? Thanks

    * This sample shows how to list all the names from the EMP table
    * It uses the JDBC THIN driver. See the same program in the
    * oci8 samples directory to see how to use the other drivers.

    // You need to import the java.sql package to use JDBC
    import java.sql.*;

    class Employee
    public static void main (String args [])
    throws SQLException
    // Load the Oracle JDBC driver
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

    // Connect to the database
    // You must put a database name after the @ sign in the connection URL.
    // You can use either the fully specified SQL*net syntax or a short cut
    // syntax as ::. The example uses the short cut syntax.
    Connection conn =
    DriverManager.getConnection ("jdbc:oracle:thin:@dlsun511:1721:dbms733",
    "scott", "tiger");

    // Create a Statement
    Statement stmt = conn.createStatement ();

    // Select the ENAME column from the EMP table
    ResultSet rset = stmt.executeQuery ("select ENAME from EMP");

    // Iterate through the result and print the employee names
    while (rset.next ())
    System.out.println (rset.getString (1));

    Thanks for this info. We have something similar to this, but if the connection fails to the database it just errors with:
    Cannot connect to DBstore ("jdbcracle:thin:@dlsun511:1721:dbms733",
    "scott", "tiger");

    We wanted a test to give a error like an ORA or TNS error number. Or something like tnsping or sqlplus. We wanted to do this test without loading Oracle Client. Is this the only solution?
