I'm trying to call a SIPp command from a servlet, this is the response I should get:

Resolving 193.5.226.181...

And if I launch the servelt I get this:
Resolving 193.5.226.181...
And the other part is somehow kicked out.
I'm using the Tomcat application server

Put this snippet in your servlet:

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("SIPp"); // or whatever
InputStream is = process.getInputStream();
OutputStream os = response.getOutputStream();

int data = 0;
while((data = is.read()) != -1)
{
    os.write((char)data);
}
response.setContentType("text/plain");


Just invoke this servlet and you should see the output
on the browser
