Runtime.getRuntime.exec() not working when Tomcat is made a windows Sevice

Question

Hi,
I am working on a web application which launches a exe file on subitting the form. I am using Apache Tomcat 4.0.6 to run the web application. Initially Tomcat was not made a windows service on my machine and when I launch an exe it is launching without any problems. I used the following command to launch the exe file:
<code>
Process p = Runtime.getRuntime().exec("C:\\Program Files\\Mercury Interactive\\WinRunner\\arch\\wrun.exe" + strWROptions);
</code>
The above command launches WinRunner on the local machine.
without using tomcat if I just compile and run a test program with this command, the exe is launching perfectly. But, Once I made tomcat a windows service on my machine the exe is not launching.
Also, a process is being created in the windows task bar named wrun.exe once I submit the form but WinRunner is not lauching on the desktop.
Can any one please help and suggest me.
Thanks,
Ramesh

The version of Java I am using is 1.4.2. Even without
using the string array as you mentioned, the exe
(wrun.exe) is launched on my desktop if I don't run
Tomcat as a windows service. But the problem arises on
making it a service :-(
That is strange because going by the documentation what you have been using should never work. I can't test it though, I'm not on MSWindows at the moment..
Now, when I use this string array convention, I am
getting an error saying "The tool could not launch..
some error occured".
That's not a Java error message, it must come from WinRunner. This means that you have succesfully started WinRunner (great!) but something else is wrong; maybe the parameters you pass to it are incorrect.
How would you run it on the command line? Like this?wrun -t "D:\L5_QE\L5A\Initial" -create_text_report on -runThat line executes the wrun program and passes it five parameters, not three. The first parameter is "-t", the second "D:\L5_QE\L5A\Initial", the third "-create_text_report", the fourth "on", and the fifth "-run". The array of strings that corresponds to that line isString[] command = {"C:\\Program Files\\Mercury Interactive\\WinRunner\\arch\\wrun.exe",
                "-t", "D:\\L5_QE\\L5A\\Initial",
                "-create_text_report", "on",
                "-run"};
