Java ProcessBuilder using authentication

Question

I am executing an external application using java process builder.

for eg

./appl -file user@host:/tmp/out.log

This application first retrieves the file out.log from the external host and then executes. Also, once the above command prompt is executed, it prompts for the host password.

How do I achieve this using java process builder? I tried to enter the command in the below mentioned way. However it throws an error that host is not found.

List<String> command = new ArrayList<String>();
command.add("./appl");
command.add("-file");
command.add("user@host:/tmp/out.log");

As you have explicitly mentioned: Also, once the above command prompt is executed, it prompts for the host password.

I believe the reason that the command is not being executed because the sub-process that you have triggered needs an input(host password),which you are not providing. Hence, you need to make an OutputStream to provide an input to your sub-process. For starters, read this question.

I tried to do this, however it does not seem to work. I am currently starting a new thread which reads the output generated by the external application. The java program just hangs.Is there any working example
