sending data from client to server

[Ashu]

Hi Everyone,

 

I have a requirement that, I have to search something from the db and get back some results(Like a search button functionality).For this I am giving some inputs.

I have to send these inputs(like Beans) to server side.

I am using GWT2.4 request factory.

How can i do this?

do i need to use value proxies here?

Yes, with ValueProxys you can send data/bean like objects between client/server that do not have a database identity.

Thanks for the reply.
I have one more small doubt.
Shall i use the same proxy for the return result.

could you please provide me the sample for this criteria.

Sounds like it doesn't make sense but I don't know your app nor what you want to search. 

If you search for some data in your database then you probably want to return a list of EntityProxy-s as a search result (if you want to display the search result). If your search is more like a server side calculation, e.g. "How many matches do I have for that search query?", then you would return an Integer for example (or a ValueProxy / List of ValueProxy if the result is more complex and does not represent a database entity).

it returns the listof value proxy.

i have one more query that how can i set data from client side to value proxy.
if possible could you please provide me the sample example to meet my criteria.
Thanks
