Hi
I have posted this uder new releases and raised a ticket with Servoy and had no response on how to fix this except to clear the java cache.
This problem accured when i upgraded the server from the previous release to Version 3.5.1-build 514.

Thanks

We have the same problem. We get this error:

Anyone else with this problem? Any ideas?

The issue was caused by the fact that the Server version of Java 1.5 was beyond 1.5.0_07 and the mac clients (are at that version) did not like that.
Seems to be an incompatibility issues with Server versions of Java 1.5 being higher...
After upgrading to 1.6 the issue was gone.

Hmm. It's not so much fun to upgrade Java on Linux. Is there a version 1.6 for Linux at all (not really my world...)?

by **IT2Be** » Fri Sep 21, 2007 5:18 pm

I do think so since it is maintained by Java but I also believe it depends much on the linux distro you use how you can get it.

It's not dependent from the distro, you have to dowlnoad directly from Sun website, the difference between distros is only the installation procedure and the configuration of the JAVA_HOME shell variable.
Anyway I would be very careful before upgrading to Java 1.6 on linux...

That's what I thought. In short: after installing Servoy 3.5.1 the smart client is broken on Intel Macs, it seems. Maybe Servoy can figure out what has changed that now disturbs the Mac and fix that? I don't think that it should be necessary to spend a day playing with Java on Linux just because you updated Servoy to the next (minor) version...

Can I get a confirmation on this?

Servoy 3.5 Client will not work with Intel Macs.

And it's due to Java.

by **patrick** » Wed Dec 05, 2007 10:14 am

No. It does work. But it requires Java 1.6 on the server.

Lately I've tested Java 1.6 on Ubuntu server (6.10) and I have to say that it's working perfectly now so you can ignore my previous post and go for it.

Which Mac OSX 10.5 doesn't have.

And more bad news... I think trying to install the 3.5 Client
does something to the existing 1.5 Java so that a 3.1 Client now won't work...

Anything I can do about that?

Servoy really needs to update the information on the
downloads page.

Servoy does absolutely nothing to the Java install.
I have been testing with different Servoy version clients yesterday and have seen nothing like that...

The Servoy download page says

- - - - - -

1. Requirements

Java:
Servoy is a Java application - you will need a Java SDK 1.4 (or higher) compatible virtual machine installed on your system.
The latest SDK for Windows, Linux and Solaris is available from Sun for free, a suitable Java is already installed on
Mac OS X 10.2 and higher if you have run all Software updates provided by Apple.
Click here to download Java JRE 1.5 (needed for Servoy 3.x or later)

If it had said Java 1.6 that would have saved me some time!

There is a signature problem with certain versions of Java on the Mac only. It also works with some 1.5 versions, but not with the latest. Strange problem, yes. There has been some discussion about this here, however. It took me a while to find out also.

We have also the major problem that the servoy client 3.5.3 will not start on Intel Macs with OS X 10.4.11 and the latest release of Java. For that it is regardless of witch system the server is running. We have testet it with Servoy Server 3.5.3 on WinXP, Win 2003 Server and Mac OS X Server 10.4.11, all of this with the latest Java release.

Any ideas how we can fix this problem?
