Tomcat Context Initialized Event

Question

Hi guys, I am having the following error while using a JNI code..
- Exception sending context initialized event to listener instance of class com.broadmediatechnology.licence.LicenceManagerContextListener
java.lang.UnsatisfiedLinkError: init

        at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:409)What I am trying to do is to load a C library on Tomcat startup event.. Here is my code snippet...
public final class LicenceManagerContextListener
    implements ServletContextListener {
  public void contextInitialized(ServletContextEvent event) {
    SystemManager.init();
  }And my init method is a native method in SYstem Manager class... It doesnt look like a Class loading problem..previously i was having library not found error, then I put these lines in Tomcat Start up script..
export CLASSPATH=$CLASSPATH:/etc/getmetv
export LD_LIBRARY_PATH=/etc/getmetv
export JAVA_OPTS=-Djava.library.path=/etc/getmetvCan anyone tell me what exactly is going wrong?
Thanks

For more information..my .SO file is placed in /etc/getmetv
The name of SO file is libgetmetv and i am loading the library as
static {
    try {
      System.loadLibrary("getmetv");
    catch (Exception e) {
      e.printStackTrace();
  }
