title: "A Java Exception has Occurred" Apache POI Error
body: <p>Im writing a program in java that takes an excel sheet from a local file and uploads the values given into the program for some calculations. When I compile inside eclipse everything works exactly as it is supposed to, but when I create a runnable jar file, I get a popup error "A Java Exception has Occurred". I went through the code, and if i remove the method to load the values from the spreadsheet the runnable jar works just fine. But if i put the code back in to load the values, it breaks. What is happening in this block of code that causes the whole program to break?</p>
