I am trying to use of C-api in our java application [OS-SunSolaris 5.6, JDK1.3]. In a java application JNI call works fine. I have placed the class in a package and invoke the JNI in a Servlet, I received the following error. 500 Internal Server Error /demo/test2: javax.servlet.ServletException: displayAMS java.lang.UnsatisfiedLinkError: displayAMS at com.csi.Postal1.AMS.AMSTesting.displayAMS(Native Method) at test2.service(test2.java:32) at javax.servlet.http.HttpServlet.service(HttpServlet.java:865) at allaire.jrun.servlet.JRunSE.service(JRunSE.java:1013) at allaire.jrun.servlet.JRunSE.runServlet(JRunSE.java:925) at

==================================================================
I am able to overcome the above error.
made code change in the 'Native function' to include packagename
(eg: Java_com_csi_Postal1_AMS_AMSTesting_displayAMS).
I am still having problem with the c-function call within the native fuction 'displayAMS'. I examined the logfile on the application server (default_out.log). That indicated it is succesful to call the 'native function' and the servlet fail at the point where it make a c-api call.
The application server shuts down and
I received the following following error message.
