no ocijdbc12 in java.library.path

Question

I am trying to make a connection to oracle through java program using OCI driver.

Following is the configuration.

• Windows 7, 32 bit.
• JDK 1.7
• Oracle client 11g R2.

ojdbc7.jar in the class path of my standalone application. But I am getting following exception:

Exception in thread 'main' java.lang.UnsatisfiedLinkError: no ocijdbc12 in java.library.path

I tried connection using thin driver. For thin driver it is Connection Succeeded. I googled but was not able to figure out the solution.

Please help me solve this problem.

Answer 1

I had the same issue, it was just the external folder of the my *.ora files which was not there any more, I pointed to it again via (menu navigation):

• Tools
  • Preferences
    • Database
      • Advanced
        • tnsnames directory

It solved it!

Answer 2

To use the oracle OCI driver you should have the relevant dlls in your java library path.

https://docs.oracle.com/cd/B28359_01/java.111/b31224/instclnt.htm#CHDIHGEF

Make sure to reference the correct release, both in term of 32/64 bit and version number.

Answer 3

it has been resolved by setting oracle client Tools->Preference->Database->Advanced->Use Oracle client->(choose path of oracle client) ex: Instant Client: file:/C:/Oracle/product/11.2.0/client_3/

Answer 4

For JDeveloper 12c, if you come across this issue set up an environment variable referring to ojdbc jar"

-J-Djdbc.library=\ojdbc6.jar"

Answer 5

I had a similar situation.

The solution turned out to be to enter the connection property and from this level to reconnect.

I will add that the problem appeared after the installation of oracle express during which an error occurred and the installation was not completed

This worked for me:

1. Rename the C:\Users\username\AppData\Roaming\JDeveloper\System folder

2. Run the Project from Jdeveloper

3. Close the Jdeveloper

4. Rename back the System folder and try running the project and update the mapping in VO
