Java MapScript UnsatisfiedLinkError

[Ryan Ollerenshaw]

Using this bit of code my java servelt reports that the mapscript has 
loaded. 

static {
         try {
             //System.loadLibrary("mapscript"); //load native library
             
System.load("/etc/tomcat5/webapps/my_test/WEB-INF/src/libmapscript.so"); 
//load native library
             System.out.println(" * mapscript native library loaded *");
         } catch (Exception e) {
             System.err.println(" * error loading native library *");
             System.err.println("Error is: " + e);
             e.printStackTrace();
         }
    }

although i am still getting a
UnsatisfiedLinkError: no mapscript in java.library.path when i reference 
any of the mapscript functions for example:

mapObj map = new mapObj("/var/www/html/mapserver/htdocs/display.map");
       

Any ideas why this is?
