Calling JNI from my servlet

Question

Hai,
I am using a servlet and I am calling the JNI method, but it is throwing an error like
"java.lang.UnsatisfiedLinkError: check_file". (check_file is my JNI method.)
I have checked the included header file name and function name, they are proper and correct. Can any one tell me some solution forthis problem. Thanks in advance.

Hai ,
I found the solution for this query from jguru forum. I thought it will be helpful for persons like me, so i am posting it here. Consider the flg. example.
All programs are under package "com.myprogram"
MyServlet.java (My servlet program)
GetInfo.java (My Java link program)
GetInfofromCLib.c(My JNI interface program)
MyServlet.java ---> Servlet that calls the get_info() native method of GetInfo.java
******GetInfo.java*****
public class GetInfo
public native void get_info();
static{
System.load("/usr/home/com/myprogram/mylib.so");
so now if u create "javah -jni GetInfo"
it will create the function name like
Java_get_1info(JNIEnv*, jobject);
but we need to rewrite this function name, so that it is representing the total path as
Java_com_myprogram_get_1nfo(....);
And also in the GetInfofromCLib.c we need to refer this way. Hope this will help others......
Thanks,
Bala....
