  • This message appears on a Win2003 Server, but works fine on my developer and my Win2008 Testserver.

  • The bean exists on the Win2003 Server.

  • The bean directory looks absolute the same like in my Developer, and absolute same like on my Win2008 Testserver

  • Problem in the smart client it looks like this:

		cRepMsg = globals.gPrtParms.cRepMsg
		cReportsDir = plugins.jasperPluginRMI.reportDirectory
		cPluginVersion = plugins.jasperPluginRMI.pluginVersion
	}	

	if(globals.gPrtParms.cDirektTo == 'scrn'){
		// ---- Report is shown in Bean  ----
		forms.ProzedJasperFrm.elements.bean_Jasper.displayMode = 'display_mode_fit_page' // JR_SVY_VIEWER_DISPLAY_MODE.FIT_PAGE
		forms.ProzedJasperFrm.elements.bean_Jasper.showReport(	globals.gPrtParms.oDummyFs,
																globals.gPrtParms.cRepNam,
																null)
	}
}

Thank you for any help.

What cold be the right procedure to find the problem ?

I just checked if all files exist and checked also the

D:\Programme\servoy6\application_server\server\work\Catalina\localhost\beans*jrbean.jar1330621547000.gz*

Thank you for any suggestions

Hi, Alessandro.

I think you are having the same problem I had a while back. See Andrei Costache’s explanation and solution at the following link and see if that helps:

Thank you for your suggestion.

If I understood it right, you mean specially this:

before using the constants provided by the Jasper plugin, first the plugin has to be touched

I have done this before (part of my code example of my later post):

if(firstShow){
      // Till Servoy 6.1 Plugin must be loaded bevor because of the Bean
      cReportsDir = plugins.jasperPluginRMI.reportDirectory
   }

And also, the absolute same code works fine on my Win2008 Testserver and works fine on my XP-Developer-Installation,
but NOT an the clients Win2003 Server…

Hi Alessandro,

Are you able to use any other Servoy bean without problems?

Regards,
Andrei

Hi Andrei,
I updated to Servoy 6.0.6 for other reasons and now, after weeks of wondering, the problem is gone !

thank you for your help
