Developer crashes on Linux Ubuntu

Classic Servoy

Inmediately after installing Servoy 4.1.3 in Ubuntu 9.04 - the Jaunty Jackalope - with Java™ SE Runtime Environment (build 1.6.0_13-b03), when trying to open any form of the sample solutions, Developer crashes.

Can it be related to the following topics ? :

viewtopic.php?t=12275 Mozilla export

http://www.servoy.com/forum/viewtopic.php?f=11&t=12488 New Install on Ubuntu - No Start?

Unfortunately, I will not have access to the Ubuntu PC until monday to test Topic 12275 suggestion.

Any idea ?

Hi achiary,

Are you actually using Sun Java? Servoy supports only the Sun JVM.

3

Yes, we are using Sun Java. And we have set MOZILLA_FIVE_HOME as suggested in topic viewtopic.php?t=12275 , but the problem remains : developer crashes.

Hello achiary.

I had the same problem and I resolved it fixing some wrong database connections.

Regards. Roberto Blasco.

Hello Roberto !

You had the problem in Linux Ubuntu ? Can you please provide more information about “wrong connections” ?

We are having the problem with Servoy sample solutions and databases.

what do you mean with crashes?

because that stacktrace (the nullpointer) is ofcourse not ok. But your servoy shouldnt really crash (be terminated) because of that
the only thing that should happen with that error is that a certain typeahaed will not paint correcty in the designer.

that nullpointer does seem to point to a wrong database connections or something like that.
are you sure everything is fine in this area?

When I say Developer crashes I mean its screen dissapears with no error message.

As I mentioned in my previous post, Developer´s screen dissapears and Developer is no longer running in the machine; there is no error message.

Regarding wrong database connections : it is happening with Servoy sample solutions and sample databases.

I can edit a relation, a valuelist, a form´s javascript code (.js) but when editing a form with form designer it crashes.

please search for you system to the real crash file
i think those should be generated. Its very weird that just such a nullpointer can crash the whole jvm. That looks like a very buggy jvm to me.

We found a transitory work around with Java 1.5 .
