How to check Acrobat Reader is installed or not?

Hello,

How to check on client machine Acrobat Reader is installed or not? if not installed, how to catch that exception.

This is the code i am using on Servlet.

byte[] content = baos.toByteArray();
response.setContentType("application/pdf");
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();

Before executing the above code, i need to check client machine supports or not.


Regards,

You can't. Besides, there are other PDF viewers apart from Acrobat Reader, so its absence wouldn't prove anything.
