5. Class.forName() error

Hi Mike, Make sure that class you are going to load is in your classpath first. second, you should look at top of stack trace, there is a reanson why it throws such exception. JDK1.3 is using same method. but you may use Class.forName("your.class").newInstance(); I wish it would help??? [ March 22, 2002: Message edited by: Sunny Liu ]

6. error using class.forName()

Hi there: I'm developing some application with an odbc link. I'm still testing it on a stand-alone PC and everything runs fine. Once I change the regular class, for an applet I'm getting some errors, so that the programs fails. Here are some lines of code: try { Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); } catch(java.lang.ClassNotFoundException e) { System.err.print("ClassNotFoundException: " + e.getMessage()); System.exit(1); } the line ...

8. PreparedStatement's Error Reporting

The JDBC drivers for most databases (Oracle, DB2, SQLServer, etc) are notoriously horrible at giving error messages. You're usually much better off (if you can) to look in the server logs. If you're using type 2 drivers (like the oracle OCI or DB2Connect), you can also turn up the client side logging and get more info. If you can't get to ...

9. Prepared Statement Error

Assuming that "STOREID" is an integer value, you need to make sure you call ".setInt(1, xxx);" on the prepared statement, where "xxx" is the int value you are searching on. This has to be done before you call "executeQuery()" on the prepared statement. When you set up a prepared statement, the question marks (?) represent parameters that you will specify at ...

10. DriverManager error

I have tried this code in both JDeveloper 10g and Netbeans 3.5. I cannot get the DriverManager to recognize the oracle driver. I can connect to the database, but the driver isn't recognized.

11. why rowset exhausted error coming?

dear pmani, first of all the way you are creating pstmt1 is not perfect. the number of records in outer resulult set will cause the same number of times pstmt1 to be created instead of this you can create pstmt1 once and reuse it by calling method clearParameters() over statement. can you paste the exception/error you are getting

12. benefit of PreparedStatement if closed due to error: maximum open cursors exceeded

Hi ranchers, I get the error "maximum open cursors exceeded", after my program runs for some time. I understand that this is occuring because either the open cursors in the db is too less or I am supposed to be closing my prepared statement obects after each use. Let me explain my requirement: This code executes the same sql query thousands ...
