Re: GWT: Decoupling Client code dependency in Server Code

Thanks Jonl for your reply.

So as per my understanding, correct me if I am wrong. when you tried to implement this separation of jars and client war. You created some rpc.blacklist as well to avoid some client classes to get converted to .js.

So what are the roadblocks you come across apart from the one mentioned above in order to implement it.
Did you get success in decoupling client/server/shared package.

I do something similar, but I decided that three jars were pointless.  I have a -user jar, which contains everything and a -server jar that I use for deployment which contains everything, except source, in shared/server.

So your hotfix, then would be for the -server.jar instead of the -user.jar.  The -user jar is only needed during client side and GWT compile.

To enforce the separation and reduce the possibility of unneeded serializers, I also have a common extensive rpc.blacklist that blacklists everything in a .client. package.  There are a few exceptions to this list though, because GWT does not enforce its own client/shared/server convention in some of the older code for RPC And Servlets so there is some serializable RPC things and exceptions in the client packages that are needed if you want to do remote logging or RPC.

My requirement is to modularize existing GWT application so that whenever required Client code can be updated and just hot fix for Client jar can be done rather than complete application war deployment.


To achieve above requirement I modularize my existing Smart GWT code into Parent-Child modules where Child modules will be Server, Client and Shared Modules. Client, Server, Shared package of application will be present in Client, Server, Shared modules respectively.

I am packaging:-
Server Module in war.
Client Module in Jar,
Shared Module in jar as well as jar containing Source code.

I put dependencies relative to Shared package in Client and Server Module code as both will be accessing Shared Module codebase.

But when i am introducing Server Module's dependency in Client Module I am getting compilation errors in Server Module as this is against GWT convention wherein Client interface is extended in Server implementation.

Can you please help me out how can i introduce server dependency in client module to achieve my requirement.

Do let me know if you need my POC code for reference.
