Re: transfer Objects between GWT and EJB
Hi, thank you for your answer, but this isn't my problem. I already know the links you have posted. It wasn't a problem fpr me to send Strings between GWt client and a Session Bean and to store an entity in a database. My problem is that I want to send Objects between GWT and EJB Project like the Example Company object above. The communication between GWT servlet and Ejb project works fine. I can call methods and so on. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: transfer Objects between GWT and EJB
Hi, but how should I represent the entities on my gwt Side? When I create a Company Pojo there on the gwt side I would't anyway not be able to transfer it. Or you mean I should use Wrapper on the Servlet to transfer the Entites from my EJB Project to Pojo's from the gwt side? On 2 Dez., 02:53, Mark wrote: > I dont know that you can do that directly.

transfer Objects between GWT and EJB
Hello, I have got a question because of the architectur of my project. At the one side there is a GWT Package with the Client Side and also a Servlet to communicate with an EJB Project. On the other Side there is a EJB Project with Session Beans and Entities which schould be stored in a database and send between GWT Client and the database. But I don't know how I can realize that. how can I send an Object from my Session Bean to the GWT Servlet, because the GWT Servlet don't know about the Entitities Classes. Thats my Project Structur: Entities + Session Bean: http://pastebin.com/anAbCqgd GWT Servlet: http://pastebin.com/Ujjka9vT I hope that it is clear where my problem is ;) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT + EJB + MYSQL
Thank you for your answer. I use glassfish app server for my project, maybe there is something wrong? To clarify my project structur: Entities + SessionBean: http://pastebin.com/4zRHMrcA GWT Servlet: http://pastebin.com/rSUSymNi I have got a GWT Client Side where I temporally want to use POJOs from the EJB Project. Then there is a GWT Servlet, which is there to communicate with my EJB Project. At least I have got a EJB Project with my Session Beans for managing the Persistence Entities, which should be able to be transferd to GWT Client Side. When I want to test if I could persist this little example, I got the following Exception: http://pastebin.com/DEYjBrvY Seems like I couldn`t use Transactionmanagement..

GWT + EJB + MYSQL
Hello, I have got some Question concerning Serialization and persistence. At First I have got a GWT project with Client code and a Servlet to communicate with my EJB Project. In the EJB project there are some Persistent Entitie Classes with references among each other and beans to manage them. The Reference may look like this: Object A /\ Object B Object C \ Object D Mostly there are 1:n Relationships, which i have to modelling with oneToMany or something like this.. I store them into a MYSQL Database which already work with Strings. With Strings I haven't got Problems to transfer them from the GWT Client Side over the GWt Servlet to the EJB Bean and then into the Database and the same way back to the Client Side. But when I try to transfer an own created Class object (POJO?) between GWT Client and EJB, I always get an Serialization Exception. Is it because of the GWT Servlet? I read something that you have to use DTo or Value Objects? Is this correct? or isn't there a easy way to solve this? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Centering text in a Label
Hello,
I try to centering text in a Label with following CSS:

It works all except of "vertical-align: middle". The text is always at
the top of the Label.

Ok, but when I attached the Label to the AbsolutePanel and do "getOffsetWidth()", I get for Example a width of 700px for the AbsolutePanel and a width of 698px for the Label.

Is it because of the ArrayList? Thats my Class:
public class Feature implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
private ArrayList subgroups = new ArrayList();
private String context;
public Feature(){
}
public Feature(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public void addSubgroup(Group group) {
subgroups.add(group);
}
public ArrayList getSubGroups() {
return subgroups;
}
}
And that is my Call:
public void test() {
AsyncCallback callback = new AsyncCallback() {
public void onFailure(Throwable caught) {
caught.printStackTrace();
}
public void onSuccess(String result) {
Window.alert(result);
}
};
Feature feature2 = new Feature("test Feature");
Feature feature = new Feature("root");
Group group = new Group(GroupType.mandatory,feature2);
feature.addSubgroup(group);
SpeicherService.Util.getInstance().test(feature, callback);
}

Thank for your help so far. I clear the cache with no effect. Maybe i
show you my other classes.
I think the service interface have to be correct. the problem might be
by calling the service?
I call both method, test1() and test2() and only test1() get served.
@RemoteServiceRelativePath("SpeicherService")
public interface SpeicherService extends RemoteService {
String getName(String name);
String getName2(String name2);
public static class Util {
private static SpeicherServiceAsync instance;
public static SpeicherServiceAsync getInstance(){
if (instance == null) {
instance = GWT.create(SpeicherService.class);
}
return instance;
}
}
}
public interface SpeicherServiceAsync {
void getName(String name, AsyncCallback callback);
void getName2(String name2, AsyncCallback callback);
}
public void test(String ausgabe) {
AsyncCallback callback = new AsyncCallback() {
@Override
public void onFailure(Throwable caught) {
System.out.println("Server Fehler");
caught.printStackTrace();
}
@Override
public void onSuccess(String result) {
Window.alert(result);
}
};
SpeicherService.Util.getInstance().getName(ausgabe, callback);
}
public void test2() {
AsyncCallback callback = new AsyncCallback() {
@Override
public void onFailure(Throwable caught) {
System.out.println("Server Fehler");
caught.printStackTrace();
}
@Override
public void onSuccess(String result) {
Window.alert(result);
}
};
SpeicherService.Util.getInstance().getName2("miau",callback);
}

You mean something like this, or is it ok?
public static class Util {
private static SpeicherServiceAsync instance;
public static SpeicherServiceAsync getInstance(){
if (instance == null) {
instance = GWT.create(SpeicherService.class);
}
return instance;
}
}

RPC RemoteServiceServlet multiple methods
Hey,
I have got some questions about the RPC.
Is it possible to define more than one method in one
RemoteServiceServlet? And does this make any Sense?
Like this:
public class SpeicherServiceImpl extends RemoteServiceServlet
implements SpeicherService {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public String getName(String name) {
return("Server hat folgendes empfangen: \n" + name);
}
public String getName2(String name2){
return("Test2" + name2);
}
}
I tried to call both methods. The first method was served, but the
second throw the following Exception:
[ERROR] javax.servlet.ServletContext log: SpeicherService: An
IncompatibleRemoteServiceException was thrown while processing this
call.
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
This application is out of date, please click the refresh button on
your browser. ( Could not locate requested method
'getName2(java.lang.String)' in interface
'de.fhdo.kuss.client.SpeicherService' )

RPC Error: No file found for..
Hello,
sry I am newbie to this Topic. I have searched the whole day for a solution,
but I can't find the problem.
I've tried a lot, without any bettering. Hope you can help me.
When I tried to call a RPC Service, I get always this Message:
[WARN] No file found for: /kuss_projekt/SpeicherService
Thats my source code:
web.xml:
SpeicherService
de.fhdo.kuss.server.SpeicherServiceImpl
SpeicherService

-
Speicherservice:
@RemoteServiceRelativePath("SpeicherService")
public interface SpeicherService extends RemoteService {
String getName(String name);
public static class Util {
private static SpeicherServiceAsync instance;
public static SpeicherServiceAsync getInstance(){
if (instance == null) {
instance = GWT.create(SpeicherService.class);
}
return instance;
}
}
}
-
SpeicherServiceAsync:
public interface SpeicherServiceAsync {
void getName(String name, AsyncCallback callback);
}
-
SpeicherServiceImpl:

// TODO Auto-generated method stub
}
@Override
