[matipblaiso30000]

i have some problem with the RPC

[WARN] greetServlet: An IncompatibleRemoteServiceException was thrown
while processing this call.
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
Invalid type signature for com.gpac.cmtid.client.UI.VO.ParametreVO

her it is my class ParametreVO :


package com.gpac.cmtid.client.UI.VO;

import com.google.gwt.user.client.rpc.IsSerializable;

public class ParametreVO implements IsSerializable{

private static final long serialVersionUID = -5216120643768806605L;

private String temperature;
private String tad;
private String tas;
private String poids;
private String pouls;

public ParametreVO() {

}

public ParametreVO(String temperature, String tension, String
tad,String tas, String poids, String pouls) {
this.temperature = temperature;
this.tad = tad;
this.tas = tas;
this.poids = poids;
this.pouls = pouls;
}

public String getTad() {
return tad;
}

public void setTad(String tad) {
this.tad = tad;
}

public String getTas() {
return tas;
}

public void setTas(String tas) {
this.tas = tas;
}

public String getTemperature() {
return temperature;
}
public void setTemperature(String string) {
this.temperature = string;
}
public String getPoids() {
return poids;
}
public void setPoids(String poids) {
this.poids = poids;
}
public String getPouls() {
return pouls;
}
public void setPouls(String pouls) {
this.pouls = pouls;
}
}

please help me

It looks like the problem is with your greet service, not this class.
Everything looks good here to me. It may help if you post the greet
service(not the async version) and it's implementation.

[matipblaiso30000]

here my greet service :

named Iconsultation
@RemoteServiceRelativePath("greetDesktop")
public interface Iconsultation extends RemoteService{

public Boolean
MettreEnInstanceAbstractConsultationVO(connexionParametres
param,ParametreVO parametre,SymtomesVO symptomes,String
idconsultant,String idpatient,String idtypeconsultation,Date
dateconsultation) ;
}

his implementation :

public class IconsultationImpl implements Iconsultation{

//private static final Logger log =
LoggerFactory.getLogger(IconsultationImpl.class);
private IAbstractConsultationSVCO
consultation=(IAbstractConsultationSVCO)(new XmlBeanFactory(new
ClassPathResource("applicationContext.xml"))).getBean("iabstractConsultationsvco");

public Boolean
MettreEnInstanceAbstractConsultationVO(connexionParametres
param,ParametreVO parametre,SymtomesVO symptomes,String
idconsultant,String idpatient,String idtypeconsultation,Date
dateconsultation) {
return
consultation.MettreEnInstanceAbstractConsultationVO(param,parametre,
symptomes, idconsultant, idpatient, idtypeconsultation,
dateconsultation);
}
}

Just in case, have you read the doc?
http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideHandlingExceptions
and http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/rpc/IncompatibleRemoteServiceException.html

The "invalid type signature for" message indicates that the object
used by the client is different than the one known to the server (at
compile-time, a checksum of the object's fields is computed and sent
along with the object's class in the RPC payload; the same checksum is
computed at runtime on the server and compared to the one received
from the client).
See
com.google.gwt.user.server.rpc.impl.ServerSerializationStreamReader#validateTypeVersions
http://www.google.com/codesearch?q=%22invalid+type+signature+for%22+package:http://google-web-toolkit\.googlecode\.com&origq=%22invalid+type+signature+for%22

It can be the case that you didn't re-deploy the *.gwt.rpc files to
your server after making some change to the object (in case you're
using the -noserver mode):
