When I try to run Java application, I receive the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no ocijdbc9 in java.library.path

I don’t have a file ocijdbc9.* on my PC, but I have ocijdbc10.dll in %ORACLE_HOME%\bin.

%ORACLE_HOME% is correctly specified, so I think the problem is that the application is searching for the wrong version (9 instead of 10).

Both Oracle and Java Builder are freshly installed, so the problem may be in project preferences? Do you have any ideas on how to search for the place where the wrong version is specified?

    You’re missing a file from your java CLASSPATH.

    You need to add the OCI jar to your classpath.

    For my oracle 10.0.2 install on windows it’s located in 

    %ORACLE_HOME%\jdbc\lib\ojdbc14.jar

    If your application requires ocijdbc9 then you’ll have to download it from somewhere and add it to the CLASSPATH. I don’t know where to download it from, try the oracle site
