Following this tutorial

J
SP/defaultendtoend.htm, I'm developing an application MVC, I create a jsp, for
show my datas, in this jsp I have a Button in order to creta a new record and
alaso have a button to make commit. When click create button, it take me to a
new jsp where you can put the data for new record. When click submit my record
has been created but when I tried to create a new record, the application just
update the record that I Created, and the rest of button like next, previous,
commit, just stop working. Also when I tried to make a commit, it take me to
the jsp of create a new record.

LD,
You don't need to set the CLASSPATH environment variable.
Personally, I prefer not setting CLASSPATH at all and using the "-classpath" option to the "java" command.
You only need to include the JDBC driver.
Your command should be:
java -classpath C:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar test
Your error message states that class "java.sql.Savepoint" is not found.
I see the following in your CLASSPATH:
C:\Program Files\Oracle\jre\1.1.8\bin
I'm guessing you're probably running java version 1.1
Class "Savepoint" was introduced in java 1.4
Try the following command:
(Again, I recommend unsetting CLASSPATH first.)
java -version
If it doesn't say you're running java 1.4 then that explains the cause of your error message.
Also, I suggest visiting this Web page:
http://www.oracle.com/technology/tech/java/sqlj_jdbc/index.html
One of the links on that page is to the OTN forum on JDBC.
That forum contains an announcement that class "oracle.jdbc.driver.OracleDriver" is deprecated.
Here is the link:

The first URL I posted above has links to sample code as well.
It's not a good idea to do connect to the database as the SYSTEM user if you aren't intending to do administration work.
That's why Oracle supplies the sample SCOTT schema.
The login and password is usually "scott/tiger".
Story goes that the guy who developed the SCOTT schema is indeed called Scott and Tiger is the name of his cat. (Whatever ;-)
Good Luck,
Avi.
