Super Dev Mode times out on launch
Hi. I have just installed GWT 2.7.0 with the Eclipse Luna plugin, all under jdk7, When I try Super Dev Mode, I get the URL briefly in the Eclipse console, but then it appears to timeout after about 1-2 seconds, before I can even paste it into Chrome. The relevant part of the error log is: ...

Handling inbound soap message
I would like to use GWT in my next project but a non-negotiable requirement is the ability to receive an incoming soap message and parse through the xml information. Essentially we are registering to be notified of events and the notification is delivered to an endpoint you supply (which would be the GWT service) and is a POST of a soap message, with a content type of text/xml. I'm unable to figure a way to allow GWT to receive this message. I have tried to override doPost (like doGet) in my implementation that extends RemoteServiceServlet but doPost is final in GWT. I also noticed that for post's GWT expects text/x-gwt-rpc, unfortunately I have no control over the service so text/xml is sent. My hope is that there's a way I can intercept or receive the POST within my GWT implementation and then subsequently parse the soap message which should just be parsing xml at that point.

Re: how can I start a HttpServlet in an Eclipse GWT project?
Never mind, it was a silly typo of mine, I transposed the org and au in the web.xml file. ClassNotFound meant exactly that. Sometimes it pays to go to bed when tired and look at it with fresh eyes in the morning. It really does work to write a class to extend HttpServlet to handle parts of the URL space for use in development, and also production if you wish. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Chunking File Upload
So there is now way to take a file that has been selected for upload and process it before it goes to the server? I looked at Google Gears and it doesn't look like it is suitable for us to use either. I might go with a Java applet to handle the upload, but then it would have to be signed. I guess we'll see.

Chunking File Upload
I'm looking at a problem that I think I might be able to solve using GWT. We're considering using GWT for the client of our application for other reasons, but I think it might also solve this issue. We're developing a Google App Engine application that processes data uploaded to it. As you may know GAE has quota for various things, including total connection time. In our case we're running into another quota regarding database access. If our uploaded file is longer than 8500 lines, we exceed our quota and get an exception. We can envision upload files much larger than this that need to be processed by our customer. So what we need to do is process the file before it is uploaded and then uploaded it to our application in chunks, say 5000 lines at a time. Can GWT help us here? Basically when someone selects a file with 1,000,000 lines in it to upload we would like to pre-process it and change it to 200 GWT RPC calls, instead of a standard file upload. In addition, we would like to provide a progress bar, of course. Thank you. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT Grid vs. SmartGWT grid
I'm exploring using GWT for future work and for a project I'm looking at now I'm particularly interested in the Grid widget. The GWT Grid just doesn't compare to that provided by SmartGWT, but I'm concerned about using the SmartGWT libraries for several reasons: 1) It requires taking the whole library whole and it doesn't do things in really the same way that GWT does in many cases. 2) I'm concerned about browser compatibility since it relies on JSNI calls to the Smart Client library and not the Java->JavaScript transformation provided by GWT. 3) I'm concerned that by using the SmartGWT library I will be increasing the load time of the application since it will require downloading the entire library again. So what I would really like is a grid control that has a similar feature set as that provided by SmartGWT, but doesn't come with all the extra baggage. Does such a widget exist? Is there at least a JavaScript grid that can be used with GWT that doesn't come with all the baggage of SmartGWT? Am I wrong about the disadvantages to using SmartGWT? Is it a better choice than I have been led to believe by my research? Thank you. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Supported Browsers
I know this was posted over a month ago, but I would like to revive the thread. I'm writing a proposal and I'm suggesting using GWT to implement the client's front end. I would like to be able to tell him exactly which browsers are supported and which aren't and if possible tell him exactly what market share of the browsers are supported. I can't find this information anywhere. If I could just get the names and versions I can calculate the market share myself. This is the first job I've proposed using GWT on and I would really like to get it, but just saying "all the popular browsers are supported", probably isn't good enough. Is there a list somewhere?

DomEvent.preventDefault() doesn't work in IE
Hi, All,
I try to catch key down event for "F1" key and display my own help
popup. I wrote following code to handle KeyDownEvent. The method is
bind by UI Binder.
@UiHandler("takenByTextBox")
void handleKeyPress(KeyDownEvent event) {
int key = event.getNativeKeyCode();
if (key == 112) { // F1 key
event.stopPropagation();
event.preventDefault();
Window.alert("F1 pressed.");
}
}
The method firstly check if F1 is pressed. If yes, stop propagation
and preventDefault, then popup alert window. It works in Firefox. But
IE still pops up its own help window, event my alert window is also
popped up.
Does anyone have the same problem, and would you give me a hand? Thank
you in advance.

Re: mvn gwt:run vs. tomcat path conflict
David,
Thank you for replying, but your answer does not solve my problem. To
be clear, I have some non-gwt web pages that I need to navigate to, so
in my application I am navigating between plain old html web pages and
gwt pages (unlike what you described where it appeared your entire web
application lived inside gwt).
The easiest solution to the problem I described would be to find a way
for gwt:run to add a /myproject/ in front of all the pages and gwt
code under war. I.e. to get gwt:run to behave just like tomcat in the
way that tomcat prefixes all war urls with the name of the war.
I have seen some references to calling gwt:run in a "tomcat" mode, but
I did not see in any of these examples where a "/myproject/" prefix
could be specified.
In all the ways I can think of to resolve this, it will just result in
a /myproject/myproject/ url showing up in tomcat which is of course
not what I want. I need a url prefix that is just constrained to
gwt:run.
Is there a solution?
Thanks,
Ken

mvn gwt:run vs. tomcat path conflict
When I test my gwt app using mvn gwt:run, it puts the application at
the root of the URL, e.g.
http://localhost:/com.foo.bar.App/App.html
However, when I run it in tomcat, if my war is called myproject.war,
then the URL is
http://localhost:8080/myproject/com.foo.bar.App/App.html
When "/myproject/" appears in Tomcat but not in mvn gwt:run, it makes
testing a pain because any web navigation links (like Window.open("/
index.html", "_self", ""); ) will work in mvn gwt:run but break in
tomcat (since tomcat would require the URL to be "/myproject/
index.html).
Please help!

Re: Line 3: The import java.math cannot be resolved
I once needed BigInteger in GWT and took the source code for the BigInteger class and with minor editing it worked fine in GWT. Perhaps this would work with BigDecimal as well. Maybe someone on this list will know if there are any legal issues with doing this? -ken --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: gwt linux 1.5.3 oophm?
SUCCESS!
i did the webAppCreator thing, still no go.
but i finally figured out what is going wrong.
ok, get this...
it's because the laptop i've
been doing all this on uses
the XiG commercial X-windows driver, instead of Xorg.
@#$*&^!
i figured this out by replicating all this on another machine,
which has identical os version, java, version, etc. and it
worked there, scratched my head and finally realized the
only difference was the X windows software.
so, i can make everything work off my original system
by just setting a remote display to the Xorg on the new system.
i won't run it like this but at least it verifies that everything
works fine, including my original app in Eclipse, as long
as i use Xorg.
jeff, thanks so much for all your help! and everybody else
who replied too.

Sorry, Ken, that's not what I meant.
Try building a sample application as documented at this link:
http://code.google.com/webtoolkit/doc/1.6/RefCommandLineTools.html#webAppCreator
You can use the generated framework as what we used to call an
"installation verification procedure".
You do mention below that you got the hosted mode browser working; which
success means you now have an idea of what you're working toward.
With the command line tools you have an option of generating an Eclipse
project that you can import into your workspace then mash with your
Eclipse problem child into something that has better odds of working.
Bueno suerte,

ant oophm
and that seems to hang too. i get this:
Buildfile: build.xml
libs:
javac:
oophm:
then nothing.
i've tried building trunk with both jdk 1.5 and 1.6.
if i run ant hosted in HelloWorld that works fine and launches the
hosted mode browser with the app.
any other thoughts on how i could debug this? seems like others have
gotten this working in linux so i assume it's something with my
environment, or something i'm doing wrong.
thanks!

good point. i don't know if snapshot is trunk, i just assumed it is a weekly

Wow, thanks for this tip! I've been meaning to explore App Engine, and this gave me even more reason to. I just tested it all out and it works like a charm. I was worried it wouldn't allow the quick turnaround, but you can use GWT hosted mode with it. They did a really sweet job with this. Thank you also for filing the bug report. You got the gist of it. It's not just generics, it's other 1.5+ features too (like "for each" loops) but it's probably not a huge deal.

Re: GWT 1.6, JSP's wont compile.
The app server is the one bundled with GWT hosted mode, I believe it's Jetty. If you use a servlet that has 1.5 stuff in it, it works fine. When I was investigating, I noticed that the JSP does successfully produce a servlet. I copied this servlet and compiled it myself and it worked fine, even in hosted mode. I believe it's failing at the point where the generated servlet (.java) is being compiled into a class (.class). Like you said, it seems like for some reason it's targeting version 1.4 or something like that. It's confusing though that the problem is during compilation, because if you start with a servlet (rather than a JSP) it compiles with no problem. I have a feeling this might have something to do with it: http://code.google.com/p/google-web-toolkit/source/detail?r=5109 It appears that something different happens underneath when a servlet is compiled as opposed to when a servlet generated by a JSP is compiled.

Some opensource frameworks (Spring, Hibernate, etc.) are used in server side. I have configuration in web.xml. That is why I prefer to use a standalone web server.

A thought about GWT project structure
In GWT recommended project structure, client code and server code are placed in one project. I find this structure is not so development- friendly in practice. (GWT 1.6 has some new update to the project structure to make it more like standard WAR project, but client and server code are still in one project.) Client code will be eventually compiled to Javascript and run on web browser. Server code will run on web server. These two parts of code shouldn’t reference to each other. The only connection between them should be the RPC interface (sub-interfaces of RemoteService) and DTOs (the Java objects get transmitted between client and server). Any attempt to let your widget reference to an RPC implementation Servlet or let the Servlet reference to a widget is wrong. However, your Java compiler (not GWT compiler) can not detect this kind of error, as these Java classes are all in the same project, and they are “allowed” to reference to each other. You can’t detect the error either in hosted mode, because client and server code run in same JVM in hosted mode. You only can find out half the issue when you call GWTCompiler (Compiler in GWT 1.6) to translate the client to Javascript. I say half because GWTCompiler only shows you the toxic references from client to server, but not the other way. A solution would be to have three projects instead of one: MyProjectRpc MyProjectGwt MyProjectWeb MyProjectRpc is a GWT module. It only contains RemoteService interfaces and DTOs. It has no UI or widgets. MyProjectGwt is your client module. It inherits MyProjectRpc, and contains widgets. MyProjectGwt’s Java build path includes MyProjectRpc. MyProjectWeb is your server project. It is a standard WAR project. Your RPC implementation servlets go here. Its Java build path includes MyProjectRpc. Therefore, both MyProjectGwt and MyProjectWeb reference to MyProjectRpc only. If your widgets incidentally reference to a servlet, Eclipse (Java compiler) will tell you right away. To make above solution work, you need to configure GWTCompiler to output to MyProjectWeb instead of the default folder www. (-out argument will do the job.) You also need to run your own web server for hosted mode instead of GWT’s internal Tomcat. (Pass –noserver to GWTShell.) There may be better way to do it. Please share your idea for a better project structure.

Suggestions for improving GWT group
I would find this group more useful and would participate more if there were "sub-groups" of some kind. I see similar "newbie" questions over and over again, or questions about the same topic repeated many times. Searching is NOT a solution. Searching might be OK, if you are just looking for the answer to a problem and you hope someone else has already expressed the problem in the same way that you would and it has been answered, BUT ... if I am browsing through looking to help by answering a few questions, I don't want to wade through the same stuff over and over again. I also see no current way in which useful answers are retained. So kind of categorization would be useful. ? Major catagories ? Experience level ? Tags ?

Re: Your opinion sought: Jetty or Tomcat?
I will be using TOMCAT as the target server for the foreseeable future. My concern with switching to JETTY within the development environment is that bugs / issues with the interaction of GWT and TOMCAT may not be seen / address as quickly as they might otherwise be. There may also be some "psychological / political" effect --- "oh, GWT is something that works with Jetty, it used to work with Tomcat but they changed it" On Oct 20, 10:46 am, John <[EMAIL PROTECTED]> wrote: > Manuel Carrasco wrote:The most annoying issue with GWT is performance in > development mode.

Re: how to redirect to another EntryPoint class
The following code was 'hand extracted and modified" from a project I
am working on. Therefore there maybe typos.
There are also references / usages of classes not shown here, but you
do not need them.
The basic flow is:
1. In your class which implements "EntryPoint" create an instance of a
Logon panel class (of your own design) --- here mine is called
"MyLogonPanel"
2. Pass a reference to the Entry Point class ("this") to the Logon
Panel class --- so that later you can call back into this class
2. Add the logon panel to the "RootPanel"
3. In the constructor of the Logon Panel - create the necessary UI
components to display a logon message and places to enter UserId and
password.
4. Call your server code to verify the UserId and Password --- onSucess
() should call back a method in the Entry Point class
--- (here "loggedOn() ) which then removes the Logon Panel from
the Root Panel and replaces it with the main application screen.
I hope this helps.
Regards,
Ken.

MyEntryPoint.java :
public class MyEntryPoint implements EntryPoint
{
MyMainScreen screen;
MyLogonPanel logon;
public void onModuleLoad()
{
logon = new MyLogonPanel(this);
