Hi,

I have written one dll which gives me the current processes running.

I try to call that method in Java program thorugh JNI in Installshield. But some how it doesnt get called and I am not able to see the results.

Can you please help in this regard.

Thanks,
Rahul

And why you don't use InstallScript?
Is it necessary to use Java?
In InstallScript it's simple ...

[rahuld]

Thanks for your suggestion.
But basically we need multi platform support and I think Install script do not support Multi Platform.

Let me know if you need any more information.

Thanks,
Rahul

I have given you total file here. I made the text in Red where I do a call for method which is present in dll.

We have "TestImp.dll" where we have defined this method. Which will return array of the process running on machine. I have put some debug comments in that.

Please let me know if you need any information.

Thanks,
Rahul

Have you build *.h using JNI?

[Silverlay]

[rahuld]

Yes we build the header file and use it as well. After that we created dll file using CL command.

When this is implemented this is not working.

[Silverlay]

Then sorry i can't help u here ... every thing seems right for me ... (( if you will have questions in InstallSrcipt based installers i would be more helpful ... ICQ:215869316

[rahuld]

Thanks for all your help.

Can you tell me where should I put this question to get my query resolved.

Thanks,
Rahul
