When I was trying 3.5 on my server, I was able to start developer then access the active solutions from other computers. Now that I’ve installed 4.1, I can’t get around this error: _Starting of webstart clients not possible from developer (running an application server)_ It doesn’t matter if I start the application server as a service or not, or if I am running developer or not, or if I try the web client or smart client. I am testing the community edition. It’s supposed to be fully functional, is there something I’m missing? I opened developer, “checkout” the sample\_crm and it seems to be active, but I can’t access it from another computer. Thanks Bill Belanger ---

For some reason I reinstalled the JRE and now everything runs properly. Maybe there was a newer edition needed for 4.1 Bill Belanger ---

Hi Bill, What version of Java were you running before ? ---

> Starting of webstart clients not possible from developer (running an application server) BTW this is new for Servoy 4. You really have to start the application server to be able to run any client other than debug clients… ---

Thanks Marcel It seems I remember that I had to have developer running in 3.5 to access the solutions. Didn’t make sense, but it seems to work the way I expect now, developer closed. app server running. I really don’t know what version of Java I had. I just had a button that said to check if I had the correct version of the java client, and I had to wait for the coffee cup, then everything worked. Bill Belanger ---

I have the same error message, but only from one machine. If I connect from another machine, everything works fine. The problem occurs after a black out in the office. When I connect via Powerbook over a VPN connection I can start the Servoy Client without problem. I checked the Java Versions and both are on Java SE 6 (64 bit) and on both machines I have not yet done the new OS X (10.6.3) “Java for Mac 10.6 Update 2”. Should I do that? Does it work? On another machine I did the Java update a little while ago, but now can’t connect to Servoy anymore, however, this installation or machine is messed up anyways, so I did not pay much attention to the Servoy problem there… Any help appreciated! Thanks Reto – Servoy version 4.1.5 -build 687
