Java Powershell Exchangeonline in Tomcat directly doesn't work but using tomcat in netbean works

Question

Hi,

I've the following java code to start a powershell script that connect using Connect-ExchangeOnline.

It works perfectly when invoking it from command line and from within a JSP with the tomcat within Netbean IDE.

However, if I run the same JSP in just tomcat itself (without Netbean) it hang with error timeout.

Do note, the environment I am running this code has a Proxy Server and all the necessary netsh winhttp set proxy xxxx has been performed.

Have anyone encounter this before?

Best Regards

StringBuilder sbInput = new StringBuilder();
StringBuilder sbError = new StringBuilder();

String[] commandList =
{
"powershell.exe", "-ExecutionPolicy", "Unrestricted", "-noprofile", "-noninteractive", "c:/temp/test.ps1"
};
ProcessBuilder pb = new ProcessBuilder(commandList);
Process proc = pb.start();
proc.getOutputStream().close();
InputStream inputstream = proc.getInputStream();
InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
BufferedReader bufferedreader = new BufferedReader(inputstreamreader);

String line;
while ((line = bufferedreader.readLine()) != null)
{
sbInput.append(line + "\n");
}

inputstream = proc.getErrorStream();
inputstreamreader = new InputStreamReader(inputstream);
bufferedreader = new BufferedReader(inputstreamreader);
while ((line = bufferedreader.readLine()) != null)
{
sbError.append(line + "\n");
}

I've managed to solve this issue by dedicating an account in "This Account" under the "Log On" tab of the Tomcat "Services". Not sure why though, but it works perfectly again. :)
