hello every body;
i created a web application with GWT and for persistence i use the google
app engine datastore but , to transfert data between server and client i
should use DTO(data transfert object) but i don't know how can i do it,
so i will be grateful if someone can help me with example
Hello Akram,
Data Transfer Objects are just simple POJOs which are used to transfer
data to the client.
Take a look at Dozer to map data from your business objects to DTOs:

You have to make sure that you directly call Window.open() in the

Use pure JSON with overlay types (almost no overhead) and if its still too

You could create one dialog and four widgets that are the dialog content.
When the label is clicked, call setWidget() for the desired contents (and
