Subject [jira] Commented: (HARMONY-4696) [classlib][swing][html] JEditorPane doesn't recognize HTML by file name
Date Thu, 30 Aug 2007 17:02:34 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-4696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12523882

Vasily Zakharov commented on HARMONY-4696:

Simple black box testing of RI shows the following results for 'new URL("file:fileName").openConnection().getContentType()'
and 'new JEditorPane("file:fileName").getEditorKit().getContentType()' respectively:

If file is named *.html, regardless of content: text/html, text/html
If file is named *.rtf, regardless of content: application/rtf, text/rtf
If file is named *.txt, regardless of content: text/plain, text/plain
If file is named differently, but contains HTML code: text/html, text/html
Otherwise: content/unknown, text/plain

In other words, it means RI implementation of JEditorPane() fully relies upon URLConnection.getContentType()
for determining content type, and just converts application/rtf to text/rtf and content/unknown
to text/plain.

>             Project: Harmony
>          Issue Type: Bug
>          Components: Classlib
>            Reporter: Vasily Zakharov
>            Priority: Minor
>         Attachments: Harmony.jpg, RI.jpg
> The following simple test demonstrates the problem:
> import javax.swing.JFrame;
> import javax.swing.JEditorPane;
> public class Test {
>     public static void main(String argv[]) {
>         try {
>             JFrame frame = new JFrame();
>             frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
>             frame.add(new JEditorPane("file:test.html"));
>             frame.setSize(150, 100);
>             frame.setVisible(true);
>         } catch (Exception e) {
>             e.printStackTrace(System.out);
>         }
>     }
> } 
> test.html:
> normal <i>italic
> test.html contains HTML code not clearly detectable as HTML. However, this code is contained
in file having .html extension, and it's enough for RI to use HTML renderer. Harmony doesn't
do it. The attached screenshots demonstrate the results on RI and Harmony.
