Button action to execute *.dll pop ups 'you are attempting to open a file.

Question

Hi
I am trying to run a simple program using a button which runs a .dll created from an .exe that writes output to a text file. My code is
public String button1_action() {
try {
String[] command = {"cmd", "/c","F:/CreatorProjects/Button1/WriteFile3.dll"};
Process p = Runtime.getRuntime().exec(command);
p.waitFor();
//System.out.println("return code: "+ p.exitValue());
} catch (Exception e) {
log("Check button fault here: " + e);
return null;
When compile, run and deploy it pops up a message 'You are attempting to open a file of type 'Application extension' (.dll) asking me either to open or cancel. I wanted the *.dll use its class file and execute write on *.txt file. If I run it from command line it is working.
Also I don't understand the message in log file:
sun-appserver-pe8.2|org.apache.catalina.core.StandardContext|_ThreadID=15;|error stopping
LifecycleException: Manager has not yet been started
Any help in this regard is greatly appreciated.

First question: Is it a Java dialog or a dialog from the OS?
If OS, can you try to create an *.exe file which would do the same thing?
