Using java.util.Collections in GWT application

[fjarenales]

Hi folks,

I'm trying to use Collections and the method synchronizedList. I have
something like this:

private List<UserBean> myList = Collections.synchronizedList(new
ArrayList<UserBean>()), where UserBean is a java-bean used in my
application.

When i try to compile this, i get the next error:

The method synchronizedList(List<UserBean>) is undefined for the type
Collections.

May i have to configure or, maybe, inherit something in my GWT
application.

Kind Regards,

Javier

If the code you have posted is meant to run in the client, the synchronized if I am not mistaken does not apply. There are no threads there.

Alfredo

Collections.synchronizedList() is not emulated by GWT (see: http://code.google.com/intl/de-DE/webtoolkit/doc/latest/RefJreEmulation.html)

Your client code runs in a single thread in the browser so there is no need for synchronizedList.
