Unable to run Java Native Interface (JNI) in Websphere Built-in JDK5

    Hello All,
    I have a java native interface code (A jar file) which calls a .so library deployed under AIX environment, the code worked smoothly when I try to ran it using both JDK 1.4.2 and JDK 1.5 installed under this environment, but unfortunately I got a strange error message when I try to run it using the bundled IBM 64-Bit JDK5 which comes with the default installation of WebSphere Application server, it gives out the following message:

    "Invalid Magic Number" - "Initialization Error"

    So I'm wondered here if there is some kind of configuration which needs to be tuned inside this Websphere bundled JDK in order to make it work, and what are the possible differences between both JDKs that may occur such error, taking into consideration that they both ran inside the same AIX box.

    my second question here, is there a possible way to make a Websphere application server to initialize and work using the standard JDK 1.5 "which is installed inside the AIX OS" instead of using it's default built-in JDK ? and if so what are the required steps to do so ?

    Followed is the detailed information of my box:

    -AIX 5.3 TL6 "5300-06"
    -IBM Websphere AS 6.1.0.17

    Sorry for being long and your help here is highly appreciated as this issue conflicts with our project delivery.

    Thanks A lot,

    I.Issa
