Using a proxy in dev mode
In my prod setup I would like to have a proxy (nginx, apache), in front of my jetty server, to handle the https, static file transfer, etc... In dev mode I would like to have the same setup, but only install the proxy and use the existing embedded jetty. I would also like to be able to not use the proxy sometimes. Before I start diving into doc + attempts, is there an obvious reason why this would not be possible? has anyone set up such a configuration before? any recommendations?

Removing war directory from GWT project
Hi. I have such a project structure that there is one root project and several subprojects. Subprojects are treated only as modules and are not compilable in sense of regular servlets. Thus, I wanted to remove all war directories, because they are useless (except from the root project's war). The problem is that GWT throws en error when there is no web.xml file in project. Do you have any idea how to get rid of these wars? Thanks! Cheers -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Confusion with MVP.
As in many cases, I'd say that “it depends”. Would there be a value in using MVP for the tile? assuming a yes, would there be a value exposing the use of MVP to the *user* of the tile? (for instance CellTable and friends use MVP, but it's an implementation detail; from the outside they're just widgets like any other). If you go the MVP route, have a look at http://www.google.com/events/io/2010/sessions/gwt-continuous-build-testing.html; it explains how Apache (ex-Google) Wave uses MVP all the way down (down to the level of buttons!)

Re: Using a proxy in dev mode
I am developing on Mac and I am using the bundled apache server as proxy. The document root is my project's war folder and server requests are proxied to the backend. The backend could be an external server or the embedded jetty that comes with GWT. You could also configure multiple vhosts along with corresponding host entries in /etc/hosts and different server proxy rules, e.g. https://app.embedded.local proxies to jetty and https://app.remote.local proxies to an external server or something like that. In production we use nginx instead of apache in front of our app servers to serve static content and to proxy server request to the backend using nginx load balancing. Works pretty well for us. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to change css style during runtime?
Rather than setting the primary name, you could create a new style that
modifies the property, and add or remove that name. I'm assuming below
that cellTableKeyboardSelectedCell is for that purpose, so you could do
widget.addStyleName(cellTableKeyboardSelectedCell). If so, I'd make the
rule .cellTable.cellTableKeyboardSelectedCell.
Even better would be to use a dependent style:
.cellTable.cellTable-keyboardSelectedCell {
border:
}
and then in your Java code:
widget.addStyleDependentName(keyboardSelectedCell);
or, to remove it:
widget.removeStyleDependentName(keyboardSelectedCell);

Probably it has to do with cellTable.setStylePrimaryName(), but I could

Re: Confusion with MVP.
As Thomas says, it depends. But, I think that for many cases where you have a UI element that isn't too complex and doesn't really allow much user interaction (or have mutable state), it makes sense just pass an event bus to the widget and have it fire events for actions a presenter higher up might care about. MVP is great, but it's also coupling and additional boilerplate, though events and hanlders also require boilerplate. But, you also get some help, eg the event bus passed to Abstract#start() removes handlers automatically.

Re: Confusion with MVP.
I've seen many developers turned off MVP by this very issue. While not prone to absolutes, I'd assert that no framework/pattern should be used as a rule. Use it when it has benefits and makes sense. In the case of MVP to the level of buttons, that might have a benefit at some obscure point in the future, but will result in a lot of code and boilerplate. I was considering the same issue when building a full page calendar widget with GWTP last week and could have made everything down to the day cells MVP, but it just did not provide extra benefit for all the code. So when thinking of MVP, then about the *other* MVP: *Minimum Viable Produc*t. Do you need a few dozen extra interfaces to make those tiles? Do your requirements call for swapping out the views for say different platform views (i.e. mobile) right now? If not, use the Widget pattern until it no longer meets you needs.

IncompatibleRemoteServiceException : The response can not be Deserialized
Folks,
I try to answer as many questions on the GWT forums as I can, but alas this
one has stumped me the last few evenings. I'm converting RunPartner.com, my
hobbist distance running site, from ExtJs to GWT having built GWT apps for
the last 2 years since GWT rocks.
I searched the old postings and found that the following two had the same
issue, but both traced it to the wrong version of gwt-servlet. I'm using
GWT 2.5.0 compiled via the gwt-maven-plugin and with all 2.5.0
dependencies. Also using GWTP. A check in the output war shows only the
gwt-servlet-2.5.0.jar there. So I'm stumped.

- Cannot deserialized ArrayList object in GWT
2.3https://groups.google.com/forum/?fromgroups=#!topic/google-web-toolkit/4ixQaJ4ixUM
*The issue*
I know there are a bunch of
reasonshttps://developers.google.com/web-toolkit/doc/latest/tutorial/RPC#serialize
things
could fail to serialize, and I've checked all of those and I kept getting
this issue. At first I though it was because of my custom serializers, or
Hibernate usage, or constructors. But, when you hit one of those, the error
message tells you so. This one tells nothing extra:
https://lh6.googleusercontent.com/-UGLHDDbNiYs/USWyg1U1cLI/CJ0/cA2AmUxcX9w/s1600/Selection_002.png
So, I got rid of all of that. I just made a method that passes a Double.
Nothing magic there. And the issue persists despite Maven clean/rebuild or
Eclipse clean or building the whole thing and just running it as JS/Tomcat.
So, I'm curious if there is any stone I've left unturned. Note that I know
the wireup is correct however as when I pass a boolean through as the
return type it jives, but not any non-primitive. On sending the Double
below, I can see it serialized coming over the wire in the XHR fine, but
the client always throws the error whether in DevMode or as a compiled war.
Hopefully I've missed something simple. Thanks for any pointers you can
provide. :)

@Override
public void onFailure(Throwable caught) {

}

Re: IncompatibleRemoteServiceException : The response can not be Deserialized
But this code still runs in the context of your app or does it also fail as a standalone mini example? Things I would do (in this order): - make sure you use source/target version 1.6 for Java7 (client and server code) - recheck that gwt-servlet.jar belongs to 2.5.0 and you are compiling with 2.5.0 (client 2.5.1-rc1 and server 2.5.0 doesn't work for me for example although its only a minor update). - As it also happens in DevMode: Breakpoint in RequestCallbackAdapter.onResponseReceived() and stepping through the deserialization process (or stop on any exception and take a look at the call stack). - upgrade GWTP to trunk/0.8 (not sure if any server stuff is included in GWTP, never used it) - Try Java6 if you have installed it -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: RPC call in Activity onStop()
Sorry for my late reaction. Indeed I don't need the callback, I just need to send a terminates message to the server to release some temporary work data. As it didn't worked, I removed this part of the code, so I can't give right now an example. But the fact is that the server didn't received the call (checked with a lot of debug logs and breakpoints). I'll try again, also with the addClosingHandler() which I didn't knew. Thanks for the suggestion. I'll come back soon. Yves Le mardi 19 février 2013 23:45:32 UTC+1, Jens a écrit : I don't see why it should not work. You can do an RPC request in Activity.onStop() but you have to be aware of the fact that the activity will continue to stop while the request is pending. So your request's callback should not do anything that depends on the activity state or its view (which will be detached after the activity is stopped). You can also do a RPC request in Window.addClosingHandler() which will be called before the window/tab gets closed. But again in this case the callback is probably never called as the window/tab gets closed while the request is pending. All you could do here is telling the server that the app terminates now and let the server invalidate the users session for example. Have you checked FireBug/Chrome Devtools and verified that no last request is made? -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: RPC call in Activity onStop()
Actually it is a subclass of AbstractActivity and onStop() is overridden. The fact the widget is being destroyed (? I am not sure of what really happens at this moment) could be the source of the problem because I have a lot of things to do during the onStop() call and something might go wrong in the client.

Re: RPC call in Activity onStop()
Try to send request in mayStop method. It may work as widget is still not destroyed nor deatached.

EAR application with war (GWT) and JPA
I have a maven project consisting of a parent project with 3 modules. 1. Modul is a GWT webapp. 2. Modul is a jar module using session beans and Hibernate. called server module 3. Modules is module that builds the ear file ( maven-ear-plugin ) In the webapp I created a GWT gui than can create records in the database. It does that with an injected session bean from the server module. Second I can search for records in the database. This is also done vie the session bean. And here is the problem. I have a hibernate entity bean in the server module. Product When searching the session bean returns a list of product beans to the GWT server implementation. The webapp knows about the product bean cause maven dependencies. I would like this list of products to be listed in the gui. But when compiling : No source code is available for type com.xx.yy.server.model.Product Sure enough, the product bean in a maven dependency. I can of cause create a new product DTO in the webapp an convert the product bean to this product DTO... but that sounds stupid. Anyone got a good solution for this. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: IncompatibleRemoteServiceException : The response can not be Deserialized
Well, seems things are quite odd. First, Tried all the suggestions:
- Now on newer GWTP v0.8.4
- Confirmed only gwt-servlet-2.5.0.jar present
- Confirmed that mvn (single prop is used) loads all GWT dependencies as
2.5.0
- Tested on Java6, Java7
Note: on Ubuntu 12.10, OpenJDK 6/7
But here is the interesting part. The exception is being thrown on line 153
of SerializerBase
private TypeHandler getTypeHandler(String typeSignature)
throws SerializationException {
String typeHandlerClass = methodMapJava.get(typeSignature); // returns
NULL
if (typeHandlerClass == null) {
/*
* Probably trying to serialize a type that isn't supposed to be
* serializable.
*/
throw new SerializationException(typeSignature);
}
The request payload:
7|1|4|http://127.0.0.1:/main/|136A4F582E1FABB50338F54C89DA7F0C|_|getDouble|1|2|3|4|0|
The response: //OK[0.44995762496622327,1,[java.lang.Double/858496421],0,7]
The value of typeSignature: java.lang.Double/858496421
But methodMapJava has the following entries
- 3=com.google.gwt.user.client.rpc.XsrfToken_FieldSerializer,
- 2=com.google.gwt.user.client.rpc.RpcTokenException_FieldSerializer,
-
1=com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException_FieldSerializer,
- 4=com.google.gwt.user.client.rpc.core.java.lang.Double_FieldSerializer,
- 8=com.google.gwt.user.client.rpc.core.java.lang.String_FieldSerializer
This looks totally incorrect. The keys are numeric (strings) in the map,
but the passed signature is just that, a signature. So it seems the map is
being populated incorrectly, or the signature sent is bonk.
So I'm left wondering why everything compiles without an issue (string mode
on) while it seems like the serializers are not correct.
Sincerely,
Joseph
P.S. The fact that primitives work is explained because all primitives have
hardcoded deserializers in RequestCallbackAdapter. Thus they don't do any
such map lookup.
