Question

Im creating an application that gets a list of .java and .class files from a chosen directory and places them in a JList. I am using Netbeans 7.1.2.

I have all the files being displaying in the JList like i want, what i cant seem to do is to open open the selected .java file in the jTextArea.

I need to get the file from the JList to pass it into the JTextArea but it is not working

     try
     {
         FileReader reader= new FileReader( jlist.getSelectedValue() );
         BufferedReader br = new BufferedReader( reader);
         textarea.read( br );
         br.close();
         textarea.requestFocus();               
     } 
     catch(Exception e2) {}

Does anybody see where im going wrong?

You need to use the read(...) method passing in a BufferedFileReader not the write(...) method if you are to read a file into a JTextArea. This should make sense to you since your goal here is to read, not to write.
