Re: cross-project gwt problems

It looks like you've already decided to nail one foot to the floor. If you can't share common code w/ the client, you'll have to make due with providing a least common denominator format (the server will pre-digest the data for the client) and use RPC to transfer the data.

Hello everyone,

currently I am working in a Project, which may use GWT to realize a
GUI. Right now i am evaluating wich advantages and disadvantages GWT
has in stock for us. Within that research i stumbled across a few
Problems which i need some opinions on from other people.

The project itself is split into two Java-projects, one of which
contains the GWT-GUI, the other one offers the infrastructure behind
the GUI, which will be shared amongst several other projects too.
Therefore, modifying the shared project should not be an option.

Now, I created a Widget for the GWT-GUI, which is able to visualize a
certain complex datastructure from the shared project. The problem I
have is the fact that the Widget makes it necessary to have the
datastructure compiled into JavaScript, since the Widget is part of
client side code. If i now break my rule of not modifying the shared
project, i can declare the shared project as a GWT-Module, and have
the datastructure in question compiled into JavaScript by GWT.

However, the datastructure has dependencies to most of the shared
project, so i would have to let GWT compile most of that shared
project, making the JavaScript file which is handed over to the client
enormously large. Moreover, the datastructure depends on classes in a
third-party .jar file, which i can not easily make a GWT-Module.

My question about these circumstances is: Is there any elegant way to
make the datastructure compilable to JavaScript, WITHOUT having the
whole shared project compiled, especially the external jar must not be
compiled. Or is there any other way to visualize that datastructure
without exposing it to the client-side of GWT?

Any suggestions on this topic will be appreciated.
