Access registry

[kkk]

I want to check whether MySql server is installed in a system. For that I have to access registry. Is there any way to access registry through Java code.

Simply try to open a database connection with a mysql driver should prove whether mysql is installed.

Edit: with invalid credentials and check for "Access denied for user" in the Exception message.

But I want to check during installation of a software.

What if the program was uninstalled but the registry key for it was not removed?

I tell in detail.
I want to create a installer. That installer has to check whether MySql is installed in that particular system or not? So only I want to check the registry through java.
How can i achieve this seniors?

Use another language that is more suitable to the task. Java is platform independence meaning it should not be used for platform dependent tasks.
P.S You also did not answer my question above.

Can you suggest any language to do that task?
I did not know answer for your question, do u suggest any idea for that?
I hope it save me...

C/C++ are capable languages. If you still want your installer to be a Java one then you can call the C/C++ functions using JNI.
The question was just to make you aware of the limitations of your approach. Your installer would also be useless on Non-Windows machines.

P.S There are also a few programs that generate installers for you. Google will help point them out.
