Re: GWT RPC synchronic calls

Yes, running in the JVM is better. I've tried pretty hard to make this work well and as a result, I don't recommend writing integration tests in GWT (or JavaScript). Integration tests are naturally represented as a sequence of actions that perform I/O, and this works better on a platform that supports blocking I/O natively. There are design patterns to make a chain of async callbacks look more sequential, but the resulting code still ends up looking pretty unnatural and hard to debug.

Aja Jens I understand now thanks.  Tests are normal java programs that perform RPC targetting your  running gwt application somewhere else.Trying to get it work that way. Thanks again.

Jens, thank you but as I suspected I have troubles. What do you mean with "a pure JUnit test" ? you mean a non gwt program ? A pure junit test launched from a "normal java runtime", not in GWT ?

Yes. See the provided tests of gwt-syncproxy (e.g.: http://code.google.com/p/gwt-syncproxy/source/browse/trunk/test/com/gdevelop/gwt/syncrpc/test/EnumsTest.java). These are normal JUnit Tests. 

 

I thought syncproxy was a library for the gwt client side, so it is strange to me that dodn't come with a gwt module definition. The docs says (http://code.google.com/p/gwt-syncproxy/) I must instantiate the service class on the client side like this: 

private static GreetingService rpcService =
  SyncProxy.newProxyInstance(GreetingService.class,
        "http://example.com/helloApp", "greet");

When the docs say "Java Client code" it means the client side code of the server service. It does not mean GWT client code. SyncProxy.newProxyInstance() will never work in GWT client code.
