Download Stalled during initial launch with Smart Client

[SteveInLA]

The first time a user launches a solution, the Java Web Client window appears and shows a progress bar while downloading the jnlp file. During this process, which generally takes about 5 minutes, the message 'Download Stalled' appears repeatedly above the progress bar, replacing the message indicating the time remaining. Eventually, the jnlp does download and the application launches, but the performance feels laggy. We have users accessing solutions both from within and outside our network, and this occurs only for users outside our network. I have tested the speed of the server's internet connection using speedtest.net and the connection speeds look great. The server is running Java 1.6.0_07-b06 and Servoy 3.5.7 on a Windows 2003 server with a Microsoft SQL 2005 back-end. Clients are using both Mac and PC OS's and various versions of Java, all above 1.5and most at 1.6.
Any thoughts?

look into your firewall and make sure that there is no, content filtering, or something like that!!
also some antivirus products can do weird stuff!

tip: open the java console on the client to see if connections are dropped, or something.

In this particular case, Windows firewall is off and there is no firewall on the routers. Antivirus is a possible culprit. This all occurs before the Java console opens, so that doesn't help.

I also have a big speed problem, connecting to the solution over vpn. Loading forms and objects at first takes a lot of time. If forms are loaded they will reopen quick. But first load, changing forms and fireing methods takes so much time that it is normally unusable for productive work. Ok, the solution is really complex and on the forms have to have a lot of objects, but I tried to design the solution forms so easy as they can.
In the last couple of months I tried a lot of configure the connections of servoy server, the firewall and the clients. The result is: The connection only is working or not. Pretty much frustrating...

I'm getting a similar problem.

I've added a new plug-in to the Servoy Developer / Application server.
It works fine in developer.

However the client now stalls when loading.



If I replace the old version of the plugin, the client loads / works fine.

What can I do?

Do you see any errors in the java console on the client or in the log on the admin page?

I'm not entirely sure how to show the console on a mac, but there should be a "show console" option somewhere in your java settings

Hi Alex,

the best you can do is to contact the company/developer where you get the plugin.

I'll check the java console on the client and the log on the admin page,
however I not really sure what I should be looking for...

I don't actually need the plug-in to work on the client.

Is there a way to turn off this plug-in (or any other)
from loading in a client?

Alex

Could it be something to do with the file size of the plug-in?

I notice it's much larger than any other plug-in

It's 9.7 MB for the version that loads in client
and
13.2 MB for the version that won't load in client.

Is there some sort of Java file size setting I need to adjust?

Alex

To Thomas : I'll contact the developer, but I'm 99% sure it's another Java/Mac OSX issue of some kind.
