Re: Thinlet and HTTPS


Hi Robert,

firstly thank you for your quick replay.

Does it mean that if I install client/server cert into keystore
everything work without any app. changes ??

Is it possible to use MS IE cert keystore ?

We have to use a browser for our app.

Glad the patch proved useful for you.

My main goal in the approach to this problem was
to have a minimal patch that could be applied to
future versions of thinlet, with very little pain.
I really need to be able to display tables/trees
that will occasionally be in the 1-2000 element size.
I'd like to think that we can get some sort of fix
in place for this, but appreciate that this approach
might not be to everyone's taste (although it does
coexist with the original implementation) and so
might not end up in the core thinlet.

Re: Thinlet and HTTPS


Jan,

When you say that you have to use a browser for your app, I'm guessing
that you'll be running an traditional applet.  In this case, you
shouldn't have to worry at all about certificates on the client.  The
browser handles certificate verification automatically.  Just make
sure that your server has the certificate installed so that you can
make HTTPS requests against it.

I tried this before without any problems.  Just be careful with image
caching in your applet.  For instance, when you have a large tree and
you are using folder icons for the treenodes, you need to package the
folder icon with your jar file and reference the icon with a "relative
path".  Otherwise, the applet will download the icon repeatedly for
each node.

If you use Webstart instead of a browser, you have no problems but
you'll have to run JVM 1.4.2 to override the trustmanager to use
HTTPS. My clients like the look of running the apps in Webstart
because it looks like a local(desktop) application and you get to save
 a shortcut on your desktop instead of visiting a site each time.

Re: Semicolon character in property definition


Mike,

Did you find a work around for this?

Why would you want a semicolon in the property area?  I thought
properties are good for holding onto keys, not plain text.

File Dialog


[Pardon if this is a newbie question answered elsewhere -- I searched 
and didn't find an answer.]

Is there a file dialog within the thinlets package?  Or should I just 
call the AWT or Swing dialog?

Well, I've had this discussion with Robert Bajzat, Andrzej Bialecki,
Eugene Klein and quite a few others, a number of times on the original
forums last year, as well as in semi-private quite recently with both

Re: Semicolon character in property definition


Hi Robert, I may be abusing the system slightly
but I thought you could store essentially
arbitrary key/value pairs in the object properties.

Its for storing scripting language commands for
another component. (Its not meant as any kind
of alternative to Scriptlet, its just a very
convenient way of creating custom user
interfaces without extra java coding
for another system).

Everything works fine except the scripting
command separator is ; and I can't introduce
one into the property strings without it
being interpreted as the property separator.
Character entities are substituted before
the string is split into individual properties
in thinlet, so putting the hex code for ;
doesn't work. If it was changed to split on
; first and then subsitute character entities
it still wouldn't trivially work, as all the
entity definitions end with ;.

I've had to use another character (|) to
separate the commands and change them back to ;
before I execute the commands. I guess I'll just
have to live with it.

There's usually a way to accomplish things with

Re: How to embed my thinlet app in a swing panel


Hi,

I would be very grateful if somebody could give me the way to embed a 
thinlet app in a swing container (Jframe, MDI ...).

Re: Semicolon character in property definition


Sounds like a job for a simple BASE64 encoder/decoder pair for the 
_value_ part of a semicolon-separated list of {key,value} pairs.

Less complex to write, but also less efficient at encoding, a simple 
hex string encoder/decoder would work, i.e. uses only characters 
{a..f, 0..1}
