GWT Debugging with an external server
Hi, I used to use GWT's internal server to debug my code but I now have the need to use an external server. I followed the instructions in the gwt eclipse plug-in (http:// code.google.com/eclipse/docs/faq.html#gwt_in_eclipse_for_java_ee) and I indeed was successful but I now lack a very needed feature that I previously had. Hot-swapping code does not work when editing an rpc-service (myClass extends RemoteServiceServlet) because GWT uses reflection in it's code and that crashes JPDA. Now, having explained why it does not work, I still hope for a miracle. Has anyone found a work-around or solution for this issue?

Re: Possible problem with GWT URL mechanism and cache
Hi Chris, I'm sorry but as I first stated I'm not sure what underlying server I'm using as the problem arises when using the built-in server in the GWT Eclipse plug-in Is this apache? Do you know? If so, do you know where I should look for its htaccess file?

What does issue accepted means?
Hi All, I've recently run into a bug (Issue 2759 to be precise) and when I found that it existed in the issue tracker I was very pleased only I saw that it's status is accepted but the Milestone is 1_6_RC which confused me. Is it only a matter of workload which has this bug (and other bugs which are just accpeptaed) delayed for 3 versions? (if so it is understandable even if annoying) or is this bug just buried but not rejected?

Re: About GQuery
If you're using eclipse you can just add the jar to your build path :right click on project--build path--configure build path, there in the libraries tab you can select to add a jar. Once you've added it you can click on the plus sign right beside it, select source attachment and click on edit- point to the Javadoc file and you're done.

How to get a reference to the Window object using GWTQuery?
The title pretty much says it all. I'm trying to use jQuery's ability
(hoping GWTQuery has implemented it) to pass a callback function to
the window.resize something like this(example from jquery site):
$(window).resize(function(){
alert(Stop it!);
});
but when I tryi to type $(window) in Eclipse I get an error that
window can not be resolved. If anyone's interested in the bigger
picture I'm basically trying to get an indciation from the window that
is has finished the resizing operation and thus available for further
resizing.
Thanks for any help
Ittai
P.S. please no lectures about browser development and resizing as I'm
developing an in house app which just happens to use a browser.

Re: VerticalPanel insert and index
If anyone else ever wonder about this issue
I looked in the source code and the index range is actually set using
the getWidgetCount() which I think is wrong but nevermind.
As a workaround I'm using another grid with 1 column and k rows for
each column so I can have an uneven grid

Isn't this some sort of bug that you have no way to set or query an

Re: JSNI and resizeTo(height,width)
So, to summarize what I discovered is that, again, it is my fault and
not GWT's (sorry GWT team).
The resizeTo method relates to a single tab opened window and it
refers to the whole window size and not only the content size.
These two points failed me.
That's it, hope someone will benefit from this

Re: Defining a source package out of the module heirarchy (from a JAR for example)
Is there any one who can give me a direction on how I can have the common classes truly common (i.e. out of my web project) but still be able to use them on the client side (i.e. have GWT compiler translate them into JS)? Thanks a lot in advance On Oct 8, 4:21 pm, Ittai etai...@gmail.com wrote: I've thought some more about what you said and I'm still not sure of how this can work: If I add a common.jar to my project then where can I put the commonData.gwt.xml file?

Re: Defining a source package out of the module heirarchy (from a JAR for example)
That's what I was saying. Why are you saying false package? Why does it sound just wrong? I'm saying false package because the package has no correlation to the structure of the rest of my GWT project which starts with com.company.web that's why it just sounds wrong. Because it's more of a hack than a logical way. Put the gwt.xml a level higher, e.g. in com.company, with a source path=common/, but that's nowhere different from the above... Funny enough this does sound different to me. Mainly because no special package needs to be created and this path already resides in my project; Still this is a bit of a hack to me and I'd rather have the option to define a source package to a module which is not the sub- package but as I have no other option I think I'll use your suggestion. Thank you very much.

GWT-RPC and Long Polling
Hi, I have a GWT app which is currently up and working and which uses GWT- RPC for passing objects between the client and the server. The current communication is via old fashioned polling. I tried moving my app to long polling, i.e. start a request and wait until new data or timeout and only after that initiate another request, but I'm having a problem where I try to sleep myServiceImpl thread during the waiting for 500ms and it gets woken up by the GWT doPost code. Just to make things clear I would really rather not use any extension or modifying of the gwt-code and I have no problem with the threads being occupied while they wait (it's a long story but currently I'm ok with this). Has anyone any experience with this? I just want to keep this request idle until it has something new but I'm afraid I'm missing something.

Multiple modules and Servlet mapping (not RPC but RequestBuilder)
Hello all,
I'm going through my first project which has multiple modules and I'm
getting a bit stuck.
First of all I'll say that all the things I'm trying to do here I've
done already in a small one module project based on the StockWatchers
tutorial and that for all sorts of reasons I need to use my own
customized servlets extending HttpServlet and the Glassfish Server.
I'm having two problems (the project is called NewMCPU):
1. I have a module called: com.aaa.bbb.ccc and in it I build a
RequestBuilder which uses GET method and this url: http://localhost:
8082/NewMCPU/com.aaa.bbb.ccc/mcpu by calling GWT.getModuleBaseURL()
+mcpu; my servlet is defined via annotations (supported from
Servlets 3.0) like this: @WebServlet(name=mCPUServiceImpl,
urlPatterns={/com.aaa.bbb.ccc/mcpu}, asyncSupported=true)
and when debugging I see that the server returns a 404 error code so I
don't understand how or where I'm mixing up the url? I think this is
connected to multiple modules because I have 3 modules and like I said
in the smaller one module project this worked, only there the url in
the client was hardcoded http://localhost:8082/NewMCPU/mcpu; and in
the servlet just /mcpu.
2. I can't seem to debug my server side code. In the project there are
two other modules who for the time being use RPC which I was able to
debug before I started to using my server and not the built-in one but
now I can't seem to debug the server side code.
What I do is launch the Glassfish in debug mode and then start my app
in the debug as web application in eclipse.
The hosted mode shell launches and so does my app but all my server
side breakpoints are being ignored (not my client side).
I really would appreciate any help granted as I've been trying to
figure these out for the past two days...
Ittai

GWT-RPC and using my own Servlet
Hi, I'm new to GWT so I'm still trying to learn the ropes. I went through the StackWatcher tutorial and used the GWT-RPC mechanism and I think I have a basic understanding of it. I currently have a GWT application which uses the RequestBuilder to send messages to a servlet I have (using POST and GET), and my servlet (in doPost and doGet) pauses the request (this is done by using Servlets 3.0 spec) and adds it to a queue. Additionally I have a Daemon thread which runs in the background and plays the request when there is new data. This works great for me apart from the fact that I'm just sending strings for now and I'd like to utilize the RPC mechanism to send Objects. My question is this: If I create my myServiceImpl which extends RemoteServiceServlet how should I handle the doPost and doGet? I'm not sure I even understand how GWT handles the call from the client side of that asynchronous interface. Does it by any chance call the doGet for example of the servlet and makes sure it calls the required RPC method? I'm sorry if I made a mess of things it's just that I can't find more detailed technical information as exactly how this RPC business works.
