JDBC driver register issue in iAS.

Question

I currently turn to EJB development, and I encountered a problem when running a CMP sample in iPlanet. My develop environment list below:
Windows 2000 Server
iPlanet 6.0 SP3 (Installed in G:\iplanet\ias6\ias )
Oracle8i,
Forte for Java 3.0
I learn CMP Bean by study the Product sample in iPlanet ( G:\iplanet\ias6\ias\ias-samples\j2eeguide\product ). I ran the script in G:\iplanet\ias6\ias\ias-samples\j2eeguide\product\src\schema\setup_ora.bat. It register a ORACLE-OCI ,the type 2 driver. But I want to register a type 4 driver. So I start kregedit ,
removed the type 2 , and register a type 4 driver and datasource use iASAT. The entries list following:
Oracle Type4 Driver Register
DriverType:oracle-type4
Driver ClassName:oracle.jdbc.driver.OracleDriver
Driver Classpath:D:\oracle\ora81\jdbc\lib\classes12.zip
DataSource configuration
JNDI Name:bankDS
DriverType:oracle-type4
DatabaseUrl:oracle:thin:@192.168.188.31:1521:PhilipW
Username:philip
Password:tiger
Then, I run the client (both servlet and rmi), all successfully. But few days later. When I run it a exception raise to indicated that the iAS can't find jdbc driver. Message in KJS Process window list below:

I am sure the classes12.zip (the Oracle type4 jdbc driver ) is on the iAS's classpath. I guess maybe this caused by the type2 driver. I had reinstalled iAS, even the OS. but I can't resolve this problem. I
really feel crazy! Do you have any idea?
Thanks in advance.

Answer 1

Shouldn't the database URL be
"<B>jdbc:</B>oracle:thin:@192.168.188.31:1521:PhilipW"? And it could also be a good idea to add the path to classes12.zip to appserver/6.0/java/classpath using kregedit...
