Answer 1

Hai there!
Iam having the same error. N/W adapter could not establish the connection (NULL pointer exception)
Iam using win98 & oracle8.1.5.
When i try to access datbase from oracle thr' Java it gives runtime error.
There is no firewall in my system.
I don't know how to run the oracle listener. Iam new user for JDBC. Please help me.
Sometimes it gives "not suitable driver".
My coding is
/**DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());*/
Connection conn = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@67.192.41.17:1521:newemployee","scott","tiger");
} catch (Exception e) {
System.out.println(e + "");
} finally {
try {
conn.close();
} catch (Exception e) {
System.out.println(e + "");
"you should have an entry for your database in tnsnames.ora file.Ask your dba about the name ,port etc.,"
Please explain this line clearly.
If possible send me a program & all the steps to run that program.
Please help me.
Thanks in advance
