Could not launch from cache

In the java console, on Windows clients we always see this:
- Code: Select all
Could not launch from cache. Will try online mode. [Some of required resources are not cached.]
On MAC this never happens, or we dont see this message.
both Windows & Mac are on Java 1.6_22.
Can someone explain what this is? and why it is different on both platforms?

A brief google search on that message seems to suggest that this is related to starting from cache using an old shortcut, created with an older version of Java.
What happens is you remove the shortcut and let Java webstart create a new one?

So, you clear the cache, delete the shortcut, start the Smart client by accessing the JNLP on the server and then what? You get this message directly in that first session after clearing the cache? Or in the second session after clearing the cache?
Wish I had the same message here, but unfortunately not...

and does it then really download the entire client again?
If not can somebody see with wireshark or fiddler or any tool, what it does download?
Do you also have this with a basic servoy install without any 3th party plugins?

ofcourse in the first session, but also in the session after that.
I will send Johan a PM, with a link so he can see.

I have upgraded today from Servoy 5.2.3 to 5.2.4 on a Debian 5 Linux Server and cannot launch now the Smart Client. The same error on Win and Mac clients (Java 1.6.0_22):
Could not launch from cache. Will try online mode. [Some of required resources are not cached.]

I have loaded a new servoy_client.jnlp and deleted the Java resources, but no success. A quick help and fix would be appreciated.

the first error:
"Could not launch from cache. Will try online mode. [Some of required resources are not cached.]"
is because of a 3th party plugin as far as i know (we don't have that in a basic install but i have seen it with an install of harjo)
the second error is weird, do you have any (smartclient) solutions on the server?
Somehow it can't get any solutions from the server, and because of that you get that error
But i dont see any other problem like a remote call problem, so the call to the server is fine, it just doesn't return anything...

It is only a basic installation without plugins from other ventors!

I don't understand this and of coures I do have an imported solution on the server. I have made a clean import of the solution on the servoy-admin of vers. 5.2.4. Servoy is running as application server on that server machine like the other installed versions before.
I switched back to Servoy 5.2.3 and all is running well!

i can't explain it then, also that first one, but that shouldn't affect your problem.
As i said that one i did see on servers from harjo, but none of our own have that.
But the second issue, do you have then any error report on the server?

I saw something similar a few weeks ago when upgrading from 5.2.2 to 5.2.4. After trying a bunch of things including a clean install of 5.2.4, I compared the servoy.properties file I was using against one from a virgin 5.2.4 install. The only difference was on the servoy.vmClientArgs line. Removing this line allowed clients to launch again. Of course you'll want to go back into the admin pages after removing that line and put the things back in that you need.
As an aside, I didn't keep a copy of the servoy.properties file around that didn't work, but the issue may have been that it started with a space. Maybe try verifying first that in the admin pages this line does not begin with a space.

I could solve the problem by making a complete new clean install of the Servoy 5.2.4 instance!
Happy new year!
