Debugging GWT app running on external container

[Hussein Baghdadi]

Hi.
I decided to reimplement some of my application (based Hibernate, Spring and WebWork) using GWT.
I coded my new GWT application then I deployed the application to
my Tomcat container.
My main problem is how to debug my application (the GWT parts)?
With the original GWT hosted mode, this is easy as the GWT application
will run on its own container, but what if the application is deployed
on an external containter?
Thanks for your time.

Is it exhibiting different behavior under Tomcat than in hosted mode?

[Hussein Baghdadi]

I'm not sure Sir.
My problem is my GWT application is compiled to JavaScript, no more Java code is avaliable.
In GWT host mode, the application is still at the Java code level (AFAIK).
Please correct me if I'm wrong.

That's true, currently in Hosted Mode you are still dealing with Java code; once compiled and deployed it is JavaScript code - I assume you are talking purely about the client side aspects?

But Bear's comment is also true - are you seeing different behaviour in your deployed version than in Hosted mode?

There are a couple of tactics you can try.

1) You can try running Hosted mode using an external server by adding the -noserver switch to the hosted mode command. This allows client side code to be debugged as normal, but server side code comes from your own server.

2) use -style PRETTY or -style DETAILED in the compilation script and this will produce more human readable JavaScript output which you can then put various JavaScript debug statements in and debug as JavaScript.

If you suspect a JS problem you can compile the GWT code with the -pretty or -detailed (pretty plus some more) style switch. The resulting JS code will be a lot larger, but the method names in the JS will reflect the original Java class/method names.

My problem is I can't use Hosted mode since my GWT part should talk to other objects (the session object, the service layer ...)
I don't know how to use hte Hosted mode in my case since my application is deployed on external container, other than GWT built-in one.
This is why I'm building my application and compiling my GWT to JavaScript.
