i looked around on stackoverflow , google's results , couldn't find headlessexception being excepted.

here code on button click:

      private void jbutton1actionperformed(java.awt.event.actionevent evt) {                                                  string titleval=titlefield.gettext();         int yearval=integer.parseint(yearfield.gettext());         string actorsval=actorfield.gettext();         double ratingval=double.parsedouble(ratingfield.gettext());         string formatval=formatfield.gettext();         int copiesval=integer.parseint(copiesfield.gettext());          insertdvd(titleval, yearval, actorsval, ratingval, formatval, copiesval);     }          

the code web service call method:

    private static string insertdvd(java.lang.string title, int year, java.lang.string actors, double rating, java.lang.string format, int copies) {         webservicepackage.newwebservice_service service = new webservicepackage.newwebservice_service();         webservicepackage.newwebservice port = service.getnewwebserviceport();         return port.insertdvd(title, year, actors, rating, format, copies);     } 

and web service's web method:

      @webmethod(operationname = "insertdvd")     public string insertdvd(@webparam(name = "title") string title, @webparam(name = "year") int year, @webparam(name = "actors") string actors, @webparam(name = "rating") double rating, @webparam(name = "format") string format, @webparam(name = "copies") int copies) {         //joptionpane.showmessagedialog(null, (title+" "+integer.tostring(year)+" "+actors+" "+double.tostring(rating)+" "+format+" "+integer.tostring(copies)));         joptionpane.showmessagedialog(null, "values received");     return null;     } 

edit: though other question here:java.awt.headlessexception thrown headlessgraphicsenvironment.getdefaultscreendevice has similar error, error arises when trying image processing. error arises without call whatsoever such library, class, or method. i'm not trying complex, it's simple thing, throws exception isn't supposed to!

well, seemed message dialog can't created within web service. had no idea happen, since in c#.

sorry if question seemed unnecessary.
