Converting a class file to a dll

Question

Hai please help me..
I am trying to convert my .class file to a .dll file.
This is my java code:
public class DateFunctions {
     public int getTimeInSeconds(int i){
          return i;
     public int addNumbers(int i, int j) {
          return (i+j);
     public static void main(String[] args) {
          DateFunctions df=new DateFunctions();
          df.getTimeInSeconds(
Created class file DateFunctions.class.
Created jar DateFunctions.jar using:
jar cvf DateFunctions.jar DateFunctions.class
Generated dll file using bimp tool like this (Visual J# .NET tool):
jbimp DateFunctions.jar /t:library
I got the file: DateFunctions.dll
Now loaded this dll into my code (say, TSL code in WinRunner) using load_dll("DateFunctions.dll");
When I try to access the method like:
j=getTimeInSeconds(int i);
I am getting the error RPC error.
Note: DLL is loading fine. but while accessing the functions I am getting the RPC error..
What could be the reason..?
Please help...?
Thanks,
Satish

Your answer lies in the documentation for WinRunner and whatever else is calling the DLL.
Certainly Java JNI has requirements for DLLs called from Java: They have to be C++ bindings that use the native header that Java generates, right?
So now you need to look at the requirements for your WinRunner and make sure that the program translating your .class file to a DLL does it in a such a way that the bindings WinRunner expects are indeed there.
But none of that has anything to do with Java. If your Java class compiles and tests successfully, then your questions about Java are satisfied. You have to figure out what WinRunner needs and what's missing from what you supplied.
