[Microemulator-users] Problem with http in the applet

[David W. <da...@de...>]

Hi,

I'm trying to get an applet working, but it chokes on this code:

	    try {
		interp = new Interp();
		Base64Cmd.load(interp);
		HttpCmd.load(interp);
		RMSCmd.load(interp);
	    } catch (Exception e) {
		f.append(e.toString());
	    }

Specifically, on the HttpCmd code, even though the whole thing is in a
try/catch block.

Known bug?  If not, I can send code that reproduces it.

Thanks,

 I don't know if this is a bug or not. Can you send a small project
preferably with source so I can reproduce the problem.
 If code can be made public attach it to bug created here
http://sourceforge.net/tracker/?group_id=30014
 Also please add more description to English word "choke".
 Does it work in standard java application (not applet)  can you try it from
webstart?

Regards,
Vlad

PS
 If you are opening connection in applet to http host other then one the
request comes from then you application will "choke".
 You will catch exception  java.security.AccessControlException: access
denied (java.net.SocketPermission ...)

 And this is not a bug but documented feature of java applets security!  See
http://www.microemu.org/applet.html second line after title.

Ok, I created a bug, and pointed to the source code that's causing the
problem.  I realize that it's a pain/impossible for you to download
all of Hecl, compile it, etc... so just let me know what I can provide
to help out.

Sorry, was late and I was tired:-)  "Doesn't load", but right now it's
crashing my browser so much I can't even get the stack trace.  I'll
add that to the bug if I do.

Works great in standard Java.  MicroEmulator is really cool!

That's not the problem, as far as I know, unless even having
networking classes built in is problematic.  It doesn't even load.

BTW, I created a patch a long time ago, and will need to update it for
the latest code - is there any interest in something like this?

Hi David
 Sorry it took me an extremely long time to come back to your problem. Does
bug still exists?
 I see that MicroEmulator working fine on your website
http://www.hecl.org/applet/

 As to "Provide a hook to call midlet methods from Javascript" this is a
nice feature. But now we are not adding new stuff because MicroEmulator  is
migrating to apache harmony..

Vlad

Yeah, I hacked it.  The problem still exists though, as far as I can tell.

Cool!  That's great news:-)  I'm a member of the ASF myself, so
welcome aboard!  When do you think you'll open things up again to
changes?
