Executing scripts as root under Linux

Question

I have an application that is running as a normal Linux user. A small portion of the application needs to execute various linux commands that require root access. Currently, I am using sudo to call a script from java that executes these functions.
To improve error handling and error feedback, it is desired to move functionality out of the scripts and into Java. Is there a way in Java to grant specific sections of code root access?

Answer 1

I could be wrong with this, but I think you're trying to do something outside of the JVM that you're running, which in this case won't work. The only real way that I can think of is if you made a very specific program with arguments pertaining exactly to what your program needs, and use Runtime.exec() on another Java program run with the sudo command from within your current project. There might be another way, but this is the only feasable way that I could think of to do this.
In terms of error handling and feedback, how would forcing the program to use multiple users create better error handling and feedback?
edit - I think I dodged your original question without meaning to. The short answer is if you're trying to run portions of your code as one user and portions of the same program as another user, it won't work, period.
