Я работаю с проектом GWT (2.6) вместе с Spring, используя библиотеку «gwtrpc-spring».

Я пытаюсь отправить POJO с сервера на клиент, я получаю экземпляр POJO, получающий компонент Spring, и работает хорошо, но когда я пытаюсь отправить его клиенту, я получаю это исключение:

 [WARN] Exception while dispatching incoming RPC call

Мой POJO:

 import java.io.Serializable;

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

public class ApplicationItem implements Serializable, IsSerializable
{
    private static final long serialVersionUID = 1L;

    private long id;
    private String name;    
    private String path;
    private String grant;
    private String icon;

    public ApplicationItem(){}

    public void setId(long id)
    {
        this.id = id;
    }

    public long getId()
    {
        return id;
    }

    public void setName()
    {

    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getName()
    {
        return this.name;
    }

    public void setPath(String path)
    {
        this.path = path;
    }

    public String getPath()
    {
        return path;
    }

    public void setGrant(String grant)
    {
        this.grant = grant;
    }

    public String getGrant()
    {
        return grant;
    }

    public void setIcon(String icon)
    {
        this.icon = icon;
    }

    public String getIcon()
    {
        return icon;
    }

    @Override
    public String toString()
    {
        return "ApplicationItem: [" this.id ", " this.name ", " this.path ", " this.grant ", " this.icon "]";
    }
}
  

Я действительно ценю вашу помощь.
