I am trying to execute a query using a stored procedure in Eclipse, but I keep getting this error and I am not sure what I am missing to be able to execute the query.

The query works in the actual server the code would be run on, but I am trying to mimic that environment in Eclipse (That being said I know the problem is not in the code, but I am clearly missing a dependency or something? I am not sure).

The error is:

Exception in thread "main" java.lang.UnsatisfiedLinkError:
oracle.jdbc.driver.T2CConnection.t2cSetSessionTimeZone(JLjava/lang/String;)

Here is what I have in my eclipse project:

Libraries:

  • Activation.jar
  • mail.jar
  • ojdbc5.jar
  • rt.jar
  • JRE System Library[J2SE-1.4]

Order and Export:

  • ojdbc5.jar
  • rt.jar
  • Activation.jar
  • mail.jar
  • src
  • JRE System Library[J2SE-1.4]

Also, Compiler info:

  • Java Compiler – J2SE-1.4
  • generated .class file compatibility – 1.2
  • Source compatibility – 1.3

Not sure what other information I should provide..

Thanks!

    I remember getting the java.lang.UnsatisfiedLinkError when a dll that should have been on the system path is not present.

    In my case there was JAVA code which relied on some native C++ code residing in a dll. Whenever the dll was absent from the classpath the error would be observed.

    If this strikes a bell, try adding the required dll as this answer explains.

    Update

    Try this :

    Add C:\app\\product\11.2.0\dbhome_2\jdk\bin to the PATH
    environment variable.

    Also, check this thread for further clues. The OP on this thread solved his problem by doing the above.

    Update 2

    It seems that a specific version of the driver jars maybe required. Do you have the Oracle Client installed ? Take a look at this (unfortunately, badly translated) thread. Scroll to the bottom to see how that OP fixed this same problem.
