JSF - printing .txt file content

[Jason A Wong]

I'm having problems trying to get a text file to print on a JSF web page.
I'm trying to use hutputText to call the readData method. Am I doing it wrong?
There doesn't appear to be any errors in the code, and the web application launches sucessfully, but with a blank page.

    public TextFileBean2() {
        try {
            //read data from the text file
            java.io.BufferedReader in =
                    new java.io.BufferedReader(
                    new java.io.InputStreamReader(
                    TextFileBean2.this.getClass().
                    getResourceAsStream("lolol.txt")));
            readData(in);
            in.close();
        } catch (java.io.IOException IOex) {
            System.out.println("IO Error :" + IOex);
        }
    }

    private void readData(BufferedReader br) {
        // dosomethig
        String line = null;
        StringBuffer appendMessage = null;
        try {
            appendMessage = new StringBuffer(16384);
            while ((line = br.readLine()) != null) {
                appendMessage.append(line);
                appendMessage.append('\n');
                System.out.print("afshf");
                System.out.print(line);
                System.out.print("\n");
            }
        } catch (Exception e) {
        }
    }

How would you know that given this:

        } catch (Exception e) {
        }

?

Ulf was being kind. I get rather abusive towards people who swallow exceptions.

However, you should not use JSF to output ordinary text files. Or spreadsheets. Or PDFs.

JSF does one thing and does it well: processes HTML forms and formats HTML displays. Anything that isn't HTML doesn't need to go through JSF. And shouldn't. JSF is going to be trying to make HTML out of the output, and the results are not pretty.

Use a regular servlet or a JSP to output the text file.
