'Unable to connect to oracle via Pentaho. 'oracle.jdbc.driver.OracleDriver' could not be found

Hi I've just installed Pentaho Data Integration v. 5.01 and I'm trying to connect to a database. However, I'm unable to test the connection as I get the error (pasted below).

I have JDK 1.7 installed on the system as well, however I can't seem to locate ojdbc14.jar anywhere.

I downloaded that and pasted it in pentaho's \lib folder but I still get the same error.

Any solutions to this problem?

Error connecting to database [test] : org.pentaho.di.core.exception.KettleDatabaseException:

Solution 1:^[1]

Try placing the odbc jar file (eg: ojdbc5-11.1.0.7.0.jar) inside the "data-integration/lib" directory of your installation. Don't forget to restart Pentaho to make it work.

Solution 2:^[2]

1. First go to Oracle Site:

http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html

2. Download 1 file: ojdbc6.jar (2,739,670 bytes) - (SHA1 Checksum: a483a046eee2f404d864a6ff5b09dc0e1be3fe6c) Classes for use with JDK 1.6. It contains the JDBC driver classes except classes for NLS support in Oracle Object and Collection types.

3. Copy it into Pentaho folder: C:\Program Files\Pentaho\data-integration\lib

4. Close Spoon if it is open and re-open again. (transferred from the comment of @mishkin - thanks him)

That works on my Windows 7 X64 Pro with latest Pentaho 5.3 Stable.

Solution 3:^[3]

In Pentaho version 6.0 put the driver (ojdbc6.jar) in: "PentahoInstallation"\design-tools\data-integration\lib and restart the Data Integration ide.

Solution 4:^[4]

See, guys we doesn't need all these stuff. We need to paste oracle jdbc driver (ojdbc6.jar) in the following location.

C:\Program Files\pentaho\design-tools\report-designer\lib\jdbc
C:\Program Files\pentaho\design-tools\data-integration\lib
C:\Program Files\pentaho\design-tools\aggregation-designer\lib
C:\Program Files\pentaho\design-tools\schema-workbench\lib

Solution 5:^[5]

try to put ojdbc driver in libext/JDBC in your PDI path (location)

Solution 6:^[6]

Try putting the jar on tomcat library folder, then restart Pentaho.

Should be here .../biserver-ce-6.0.0.0-353/biserver-ce/tomcat/lib

There are already some drivers here.

Solution 7:^[7]

I could solve this issue by selecting Oralce Native connection > Hostname as Ip address of DB server > instead of SN00XXXX I had used DB00XXX name for the Database name.

I hope this works for such issues with oracle connectivity.

Solution 8:^[8]

In my case, the error was in Report designer

The fix: only copy ojdbc14.jar to

\prd-ce-5.0.1-stable\report-designer\lib

and restart the tool.
