Using a common code both at client and server side

[sriram]

Hi,

Do we use a common code written in java, that could be used at both
the client and server side using gwt.

for example, cache a common folder used at both the ends.

Thanks,
Sriram

sure, and in fact it is quite common to use the same code in both
places.

The easy way to do this is to consolidate that shared code into a
particular package ... something like com.foo.bar.shared

Then create a new GWT.xml file com/foo/bar.Shared.gwt.xml and add
<source path="shared"/>

your module containing your entry point would then add <inherits
name="com.foo.bar.Shared"/>

and your server code would just reference those classes like normal.

The trick here is to remember to only place translatable code in
com.foo.bar.shared. Since it is going to be compiled to javascript, it
will have to abide by all of the rules of client code.

Hi Jason,

Thank you very much.
Correct me if i am wrong.
Is this a similar way, to creating a module

[Jason Essington]

Yes, by adding a gwt.xml file, you have basically created a module,
but without an entry point defined the module cannot be compiled on
its own, only inherited by other modules.
