Answer 1

I recall that the an overload of exec method provides a parameter for the arguments seperately. You need to use that

Yup. Here is it

public Process exec(String[] cmdarray)
             throws IOException

Just make the command line and all arguments Seperate elements of the String array

Answer 2

first make a string
String cmd="/export/home/test/myapp -T \"some argument\"";
then run cmd in proc
