Can not deploy a report using JDBC connection on CR2008 Server

Question

Hi Group,
I have a report created with JDBC connection. When I tried to add it to CR2008 server, it gives an error - "An unexpected error has occurred ". Basically I want to add a report to a public folder via CMC. I am using adminstrator account.
Then I thought I need to add JDBC driver into CR2008 server. so I put oracle jdbc jar into CR2008 server classpath and add JDBC connection info into CRConfig.xml. but I still got the same error.
I also tried:
- Change the report to use native Oracle driver rather than JDBC. The deployment succeeded (but this is not what I want)
- Add a data source connection via Business View Manager, but no luck.
I know how to use/change jdbc connection with programtic way, but I just want to know if I want to use built-in components in CR2008 server without any coding the reports can be deployed and managed.
Thanks in advance.
Dennis

Hello Will,
Crystal Reports supports connections to JDBC/JNDI out of the box, and have done so for a while, whether stand-alone or published to Enterprise.
To specify where the server would search for the JDBC driver jar files, you'd change the classpath tag found in the CRConfig.xml file found on the machine where the Crystal Reports Page or Job Server is running. 
For early Crystal Enterprise 10 and before, it used Java Native Interface (JNI) to start the Java process to retrieve the data from the JDBC connection.
For later Crystal Enterprise 10 and later, it starts off a "Java Server" process, and communicates to the Crystal Reports process via CORBA TCP/IP connection.
Commonissues that may arise:  (1) CRConfig.xml not configured properly, (2) unable to start or communicate to the "Java Server" because of permissions or firewall.
Note that this is a separate connectivity map from using ADO or ADO.NET.
