Servoy 5.1.2 is released to resolve these issues, see Servoy 5.1.2 release
A Servoy 4 release will follow soon...

An explanation for plugin developers to workarround the security level change can be found here, for use with Servoy 5.1.2 or (soon to be released) Servoy 4.1.6

Change for Servoy 3.5.10?

Yes, Servoy 3.5.11 is expected next week ... but it is still far better to move on to Servoy 5
As announced over a year ago, the support on Servoy 3.5 will expire soon.

Of course. Trying...

Can anyone tell me -- we've finally gotten all of our plugins to their signed versions, but we're being forced to clear the java cache of all servoy smart client machines in order to launch properly -- is there any way around this?

yes, look at ALL your jnlp's and change a fixed version number to: "%%version%%"
(make a backup first ofcourse )

Great! I thought of updating their versions in the jnlp from an old piece of advice Marcel gave me, but then didn't know what to do when I see that Marcel's plugins now say %%version%%. So I guess it's not his that I have to worry about. Perhaps its the bean I'm using from ObjectPlanet that doesn't come with a jnlp file -- I just put the jar in the beans folder?

No just look at the jnlp's

also the client that does not start (only after java cache clear) will give you the exact plugin, which give you the problem

Servoy Server 4.1.4 build 681
Windows 2003
Java 1.6.0_17-b04

Some time ago clients logging onto this server exhibited the 'Unable to load resource: (http://192.168.20.13:8080/beans/swingbeans.jar.......' and so I followed advice and removed the swingbeans.jar from the server and restarted

Since then I have been happily opening a client on my macbook pro

It has been 3 or 4 weeks since I last did this and today it gives me that above error - but the jar is not in there to download

Any thoughts on why it should suddenly do this again

Cheers
Harry

maybe there is a cached jnlp file in the cache that still references it.
Wasn't there any change on the server? Not 1 update jar/plugin?

Try to upgrade to the latest release, because there we have a bit better fix that makes sure the the cache on the client can't be out of sync ever again.
(because all the timestamps from all the jars and jnlp's are bubbled up to the top jnlp so everything has a unique version that will change if there is a jar deep down changed)

Hi Johan

I think that I had cleared out all possible java cache data.

It may be that I had updated Java version on my MacBook Pro and that the newer Java version had caused the issue

I updated the server to 4.1.7 and I then managed to launch a client again on my machine, so it seems that the problem has gone away again now

Thanks for the reply any way

Cheers
Harry

Hi there,

I am using Servoy version 3.5.6 and with the Java update 1.6.0_23-b05 (client: Windows Vista. Server: Windows 2003). I think java has been upgraded automatically recently. When I launched the client from servoy launcher page I got the following issue:

Code: Select all

com.sun.deploy.net.FailedDownloadException: Unable to load resource: (http://server:8080/beans/it2be-browserbean.jar?version-id=1174878714062, 1174878714062)

I have copied jnlp as well:

Please help.

Thanks a lot,
Hameed

the only thing you can quickly do besides updating to a later release of servoy is delete the "empty" jars in your beans directory (like swingbeans.jar and i guess it2be-browserbean.jar) on your application server.
