title: Developing a standalone application using Java
body: <p>I want to build an application using Java related frameworks but i do not have an idea to start it. </p>
  
  <p>The description is as follows:</p>
  
  <p>I need to fetch flat files containing legacy data from UI and then send it to the structured database for storing the structured data. It is basically a conversion of legacy data into structured form. </p>
  
  <p>In this above process i want to display the error logs on the UI itself. </p>
  
  <p>How could i achieve this functionality and which framework or technology will be better to use? Is it good to use Swing?</p>
