Exception in server log

Classic Servoy

Hi guys,

I just saw this error in our server log. Anyone knows where it might be? I do not remember to change anything to a form using that table. There are more errors like that in the log.

thats just a warning stacktrace that something is in a state that we don’t expect.
Is reported before and we did do some fixes in servoy for the next release (6.0.1)

OK, Thanks Johan!

I’m having another error in servoy.log file. Can you please let me know what can be wrong there or if it may affect the server memory.

You can check the attached log, but in general this is the exception:

it is just a warning, not a real error
But what are you doing there exactly?
Somehow you have a Java ArrayList inside js directly, are you using json or something like that? Or specific plugins that are returning scriptables?

6

I don’t know exactly where it come from. Indeed the form flight_reservations_webclient it’s using some javascripts in a HTML_AREA and calls javascript using WebClientUtils.

But I also see the error for other forms: contacts, flight_plan_list

Rhino runtime detected object [contacts, flight_plan_list] of class java.util.ArrayList where it expected String, Number, Boolean or Scriptable instance. Please check your code for missing Context.javaToJS() call.

Hi, I have found other exceptions which I don’t understand them. Also please let me know if they are dangerous for the server stability.

  1. This one it says that can’t find a function of my own, but the function is there. There is a form with an OK button that is opened in a dialog from the forms.fleet_edit when it calls a method of forms.fleet_edit.
function onOK(event) {
	
	var engineTime = globals.durationTextToHours(newEngineTimeInitialText);
	if (engineTime < 0) {
		return;
	}

	engine_time_initial = engineTime;
	tacho_current_initial = newTachoInitial;
	hobbs_current_initial = newHobbsInitial;
	engine_time_initial_date = newEngineInitialDate;

	databaseManager.recalculate(foundset);

	forms.fleet_edit.initEngineTimeText(); // This is line 70

	application.closeForm();
}

first, which version is it exactly that you use?

1>
i don’t know, it just really doesn’t seem to find that function.
Are you sure it is there? And by that i mean did you really check what is running on the server?
Can you for example test once with the soluton model?
solutionModel.getForm(“fleet_edit”).getFormMethod(“initEngineTimeText”)
does it then really have it?
Are you getting this thing constantly? or did it just happen once? (and you know that onOK is executed way more often?)

2>
where do you try to get a snapshot of?
What is your first argument?

3>
You get here a request to a image/resource for a soluton that doesn’t exists…
I guess it is something what was cached in a browser and you then removed a solution having that media?
I improved the code so that this will just return an empty byte because that is what it is i gues

4>
this sounds a lot like a dialog and for that we have put in quite some changes in the next releases of 5.2 and 6

5>
this could be 2 things, or you really had a long running process and 1 other request just waited for more the a minute
or there is something else going on, if you see this happening in the log make a thread dump to look for the thread that has that stack:

at org.apache.wicket.session.pagemap.LeastRecentlyAccessedEvictionStrategy.evict(LeastRecentlyAccessedEvictionStrategy.java:61)
at org.apache.wicket.Page.endVersion(Page.java:1236)
at org.apache.wicket.Page.onDetach(Page.java:1571)
at com.servoy.j2db.server.headlessclient.MainPage.onDetach(MainPage.java:990)

if that is the case please send that stack dump over.

6>
this one i really can’t explain, that just shouldn’t really happen or you have to have 2 request at the same time 1 closing the solution
when another request (that we see here) opens the solution…

The exception says that the files are missing?

Yes, indeed the files were missing. :oops:

those are both related to shutdowns of clients.

The first is a webclient that is being shutdown and tries to handle some pending events.
You can’t do much about that, you could create a case with that stacktrace.

the second also look that there you have a batch or headless client, that is running so long running recalculate stuff
an that client is then somehow also killed or called shutdown on.
That exception is can’t really be avoided, because a client is killed when it is really still doing something
