I am creating a simple plug-in to generate Fibonacci series. In my java code I have used ArrayList<Integer> a = new ArrayList<Integer>() to store all the numbers in an Array. At the end of the code, I return the ArrayList object i.e return a. But when I call my function in Expression Rule after exporting the plugin to the plugin folder, the function doesn't seem to exist. Is this because I am returning an Array of values? What should I do to generate an array of values?

I had made another simple plug-in to fetch the factorial of a number. This worked successfully.

As mentioned by Eduardo, the plugin deployment must have failed. In my experience, I have always encountered an error whenever I tried to return ArrayList. (The exact error is: Invalid Error: Unsupported Type: java.util.List...) You have to convert it back to an array. You could use the method .toArray() for converting the ArrayList to simple array, then return it.
