gwt rpc generics java.lang.ClassT
Hi to all,
i am facing a problem with the java generics in rpc. I have implemented a
rpc service using the java.lang.classT generic and while it works fine
when i test it, it cannot be compiled. I have serialized the class that i
need to pass through the rpc and i have implemented the default empty
constructor but it still does not compile.
Here is my service and the class that i need to pass through the generic.
package com.client.model.mybay.browse;
import java.util.ArrayList;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import com.shared.source.MySource;
@RemoteServiceRelativePath(categoryService)
public interface CategoryBrowseService extends RemoteService{
ArrayListMySource getSourceList(Class? extends MySource classType);
}
package com.client.model.mybay.browse;
import java.util.ArrayList;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.shared.source.MySource;
public interface CategoryBrowseServiceAsync {
void getSourceList(Class? extends MySource classType,
AsyncCallbackArrayListMySource callback);
}
package com.sourcebay.shared.source;
import java.util.Date;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.Inheritance;
import javax.jdo.annotations.InheritanceStrategy;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
import com.google.gwt.user.client.rpc.IsSerializable;
@PersistenceCapable
@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)
public abstract class MySource implements IsSerializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
private String userId;
@Persistent
private String title;
@Persistent
private String description;
@Persistent
private String blobKey;
@Persistent
private String youtubeLink;
@Persistent
private String personalLink;
@Persistent
private Date submitedDate;
@Persistent
private float price;
public MySource() {
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getBlobKey() {
return blobKey;
}
public void setBlobKey(String blobKey) {
this.blobKey = blobKey;
}
public String getYoutubeLink() {
return youtubeLink;
}
public void setYoutubeLink(String youtubeLink) {
this.youtubeLink = youtubeLink;
}
public String getPersonalLink() {
return personalLink;
}
public void setPersonalLink(String personalLink) {
this.personalLink = personalLink;
}
public Date getSubmitedDate() {
return submitedDate;
}
public void setSubmitedDate(Date submitedDate) {
this.submitedDate = submitedDate;
}
public Long getId() {
return id;
}
}
I am using AppEngine 1.7.1 and GWT 2.4.0. Does anybody have any idea how to
fix this?
Thanks in advance,
Ste

gwt application using hibernate and postgresql
Hi to all, i have implemented a new gwt application without any app engine integration and i need to use postgresql as a database . I have managed to integrate postgresql but one of the prerequisites is to use hibernate. I am searching for about 2 days for a solution but i haven't found any and the jboss hibernate examples are not working. Has any a complete gwt example with hibernate and postgres integration? Thanks in advance. Best regards, Stefanos Antaris -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Wait dialog on rpc interaction
Hi to all, i am facing a problem while developing a web application. I have some rpc interactions with the server (appengine) and most of them are really time consuming as i am having some data analysis. Due to the delay of the response, most of my beta testers press more than one time the request button and so does this duplicates the analysis phase. How do i popup a dialog box or whatever in order to notify them that we are processing his/her request and he has to wait for a while?

http and https on google web toolkit
Hi to all, i am totally newbie on gwt and i have to implement a new web application for a company. The web application should be placed on http protocol as long as the user is not signed in and when he/she signs in the whole web application should use https. Is there any sample code, tutorial of how can i support that feature? I am thinking on using rpc. Is this the best approach for that specification?
