    A comment on your code:
    NEVER have an empty catch clause. Add at lease a e.printStackTrace() to it

    Add a println to show the value of tmp following each read.

    jTextArea1.setText(text);
    }
    catch(Exception e){}

    Replace the following line:

    jTextArea1.setText(text);

    with the following :
    System.out.println(text);

    If you see your file completely ( not only the first line ), then something wrong with your JTextArea, otherwise, if your println shows the same as
    the JTextArea, most likely something is not quite right with reading the file, maybe u don't have Return carriages at the end of each line in the file2.txt.
