Hi,
can you do me a favor got the following exception when I run the below code in the JBuilder4.
java.lang.NoClassDefFoundError: java/sql/Savepoint
     at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:266)
     at java.sql.DriverManager.getConnection(DriverManager.java:517)
     at java.sql.DriverManager.getConnection(DriverManager.java:177)
     at ucsc.Connect.main(Connect.java:17)
Exception in thread "main"
and When I run this program in the command prompt, I got the following exception
D:\>java Connect
Exception in thread "main" java.lang.NoClassDefFoundError: Connect
