5. Class.forName() error    coderanch.com

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()    coderanch.com

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 ...

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    coderanch.com

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 ...

11. why rowset exhausted error coming?    coderanch.com

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    coderanch.com

Hi ranchers, I get the error "maximum open cursors exceeded", after my program runs for some time.
