I’m in the process of moving my Servoy application server from a Windows 2000 server box to a machine running Red Hat 8. I have the server running fine on the new machine and new clients have no problems connecting. I’m running into a problem with clients that have been using the Windows box and are now trying to connect to the new server.
Upon the initial load of the client software from the server, I’m getting an error dialog:
“Java Web Start - Launch File Error”
“Unable to launch Servoy Client”
Here is a dump of the contents of the error dialog:
An error occurred while launching/running the application.
do you have a clean install of the servoy 2.0 release (in a different dir) for testing? Because maybe then the server has some mixed up jars (old and new version)
can you give me an dir listing of the servoy\lib dir? (that includes sizes and timestamps_
mpwiedemann:
Should I just perform a clean install on the server?
Will work, or do an install in seperate dir and copy all lib files to current failing 2.0 when no Servoy processes are running (are you sure you where not running the server during autoupdate in developer?, because server has file locks on jars)
This is only happening with clients that have connected to the older Windows 2000 Servoy Server in the past. Newly installed clients connecting to the new Linux server work just fine.
We are unable to explain this currently, there is also no relation between clients having started from other servers.
So when connecting to new server you always will recieve a new client application.
Some questions:
-are you sure the clients you start are all clients from the same server?
-did you shutdown all other Servoy servers so there can be no mistake from which you are starting?
Looked at the users local webstart folder and compared it to a known working system. It seems that the computers that had this problem were missing some of the JAR files that were present on the working machines. We copied over the webstart folder from a worrking machine and it solved the problem. It seems that, in our case anyway, a machine that worked fine connecting to our Win2000 Servoy server, would develop this problem when attempting to connect to the new RH Linux Servoy server.
I guess the main question would be; Why are these machines are not installing/dowloading all the needed JAR files?
I do have the same problem. Clients don’t run on customer OS X 10.3 machines after installing new Servoy solution . Did empty the cache folders but no succes…

Servoy Application Server runs on OS X 10.3.9 Server.
Found out that problem occurs when I use a copy of an excisting Servoy application. Problem is solved (and prevented) by always performing a clean Servoy install.
If the database needs standard data to function properly (for example valuelist data), install new Servoy application and copy nessesary .db files to database folder. Link these files and import solution after that!

Background:
-User has used web client in the past successfully.
-Gave user link to download smart client this week.
-User got in one day.
-User can’t get in now. She gets this message above.
I saw a thread from 2004, but didn’t see any resolution that fit my scenario.
Environment:
-Windows Server 2003
-Servoy 3.5.7 Server
-Mysql 5.0.x
-IT2BE data plugin
-IT2BE datastream plugin
-User is on Windows XP (She’s in a corporate environment that I don’t have access to, physically or remotely)
Things I’ve tried:
-redownload client
-uninstall client
-uninstall client and delete .servoy directory
Any thoughts? This is urgent for my client’s business. Thanks.
