java.lang.NullPointerException
at com.dq.foprodex.web.manager.impl.DossierJuridiqueManagerImpl.consultDoc(DossierJuridiqueManagerImpl.java:2195)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) |
l'erreur lié à cette ligne :
ServletOutputStream op = response.getOutputStream();
en faite response est null grace à ce code :
dossierJuridiqueManager.consultDoc(null,null, userid, id);
mais je n'arrive pas à savoir comment remplir response
je pense que je dois le remplir dans la page jsp
merci d'avance
Erreur "NullPointerException" liée à HttpServletResponse
