Real-time Spell checking API's for use in applet.

[Daniel Pitts]

I'd like to emulate the Firefox/thunderbird real-time spell-checking
feature in a (signed) Java applet. Right now, the user is entering data
in a JTextArea, but I'm willing to replace that, as long as the
replacement has word-wrap.

If there are good libraries available that don't have UI integration,
that's fine too, I can probably handle that part myself. Grammar
suggestion is a nice-to-have. I only need, and will probably only ever
need English correction.

To be specific, The goal is to provide red-underlined text for
misspelled words, and allow easy correction from a pop up/context menu.

This one does all of that.

Thanks.
I did forget to mention that free is very important, and open-source is
a big nice-to-have.

Hunspell is what Mozilla code is currently using, and Google suggests
that there exists Java bindings: <http://dren.dk/hunspell.html>. That
only gets whether or not a word is misspelled as well as suggestions for
the word.

The UI should be fairly simple. You can use the Highlighter class
(DefaultHighlighter is probably sufficient to use), as well as text
modification listener to figure out when words are being added, to tell
the text to only highlight a portion of the text. I'm not sure if
highlighters shift their ranges in response to text modification, though...

Native code could be a problem in a Java applet.

I forgot to mention, the library includes Win x86, Linux x86/x86-64 and
Mac x86/x86-64/PPC. The only important missing environment is Win
x86-64; perhaps Linux ARM (i.e., mobile) may be useful. Hunspell should
build on most major platforms, so it's more a question of gaining access
to such a build environment.

But what about the deployment.

JNI used to be a big no no in applets.

Better with Java Web Start ?

I'm guessing that you're asking for recommendations from users of Java
spell-check libraries rather than references to the same.

I don't have recommendations, but a web search reveals a seeming
abundance of FOS Java spell-check libraries. One that caught my eye, in
fact the first hit for java+spell+check was Jazzy.

Are there some FOS Java spell-check libraries that you are certain you
will not use?

Correct. GIMF. I found a few references, but I have never utilized such
a library, so I'm not sure which features might be useful or which APIs
are mature.

Any one that is broken beyond my ability to repair it ;-)
