Re: Problem on server side
I would put all your code in
try{}
catch(Exception e)
{
System.out.println(e.getMessage());
System.out.println(e.getStackTrace());
}
that should give your a clue ;-)

Re: Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M)
You should also increase the heap size for your application itself. You can find it under "Run configurations"->Arguments->VM Arguments. Set it to -Xmx512m - works fine for me.

Underlying TabPanel components
One thing I've learned in my experience with designing a gwt app: look
for lots of nesting. Once you understand how something is built, you can
correctly implement and style it. That being said, while it works fine
in terms of the javascript output, the tabpanel's HTML output has me
slightly confused.
The tab panel, as I understand, is created via a tabbar and deckpanel
inserted into a verticalpanel. So, that should mean the HTML would show
a two-row container table (the verticalpanel) with the top row housing
the tabbar table and the bottom row housing the deckpanel div. However,
when I create a tabpanel in gwt and then view in Firefox, trusty Firebug
indicates there is an extra div between the deckpanel div and the child
widget. Here's a very simplified example:
//gwt-code:
final TabPanel pUserTabs = new TabPanel();
pBody.add(pUserTabs);
final Button btnTest = new Button("test");
pUserTabs.add(btnTest, "Test");
pUserTabs.selectTab(0);
Test
test
Why is an extra div thrown in here? While in the above example there's
not much of a problem, I'm currently trying to tame two nested tabpanels
with further nested children, and it can be difficult to style
everything when there's something extra thrown into the inheritance that
I wasn't expecting and can't reach. Anyone ever seen this or have any
suggestions as to why it's there?

Re: GWT 1.6.4 fails to load
In case anyone is still hitting this problem... I ran into it today
and figured out that it is caused by using the same identifier for the
GWT module and the DIV that you're injecting the GWT module into (I
have a feeling it would be a problem if any DOM elements have the same
name as the GWT module, actually).

Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M)
Hello all, I created a sample GWT application using GWT1.5. then i moved this application to GWT 1.6 as instructed in the tutorial provided at the google web toolkit. after finishing i am getting the error of "Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M) ".

Multiple Entry Points in the same module
I have multiple entry points in the same module.
For example I have an Home entry point for the home page and an Admin
entry point for the admin page.
The way I am setup now - I need to check somt like this in my
OnModuleLoad:
if((RootPanel.get("someHomeWidget")!=null)&&
(RootPanel.get("someOtherHomeWidget")!=null))
{
// do the stuff
}
in order the the Admin Entrypoint not to be executed when the Home
page gets open and the other way around.
Not doing the check above also involves that if I have a div with the
same name in both the Home and Admin page whatever I am injecting in
it shows up twice on each of them.
This stinks 1000 miles away and is obviously wrong: what's the correct
way to do this in people experience?
Any help appreciated!

Problem on server side
Hi guys,
I'm facing a very strange problem. I can access the app server side, and
operate partially on it. The problem is this "partially" thing. I'd like to
know if someone can help on figuring out this issue, here is the code and
the trace of execution with prints ;)
-
Code:
public class TransactionServiceImpl extends RemoteServiceServlet implements
TransactionService {
public String startBD() {
try {
System.out.println("I'm here!");
Controller c = Controller.getInstance();
} catch (Exception e) {
return "Problem during DB start.";
}
return "DB Start succeed.";
}
}
private Controller() {
System.out.println("There it goes!");
this.bdFacade = new BDFacade();}
public DBFacade() {
System.out.println("Please get to this code!");
}
--
The execution trace is:
I'm here!
There it goes!
The call failed on the server; see server log for details
It means that I can't access the BDFacade, or any other class; instead, I
can call any Controller method, that it works fine. HELP, please! ;(
Thanks in advance.

RequestBuilder and native XSL stylesheet processing
Hello all, Here's what I have: - I have a bunch of XML file on a server describing data, and a bunch of XSL file defining transformations to HTML code. - Each XML file contains the reference to its dedicated timesheet (so that basically, using a browser to view the XML file will render it more or less correctly). Here's what I want: I want the browser's native XSLT processor to apply the XSL transformations to the XML file, so that I can inject the resulting HTML code within another page. Here's what I've done: So far I am using the RequestBuilder to fetch the XML file, which works OK, but of course the response's content is the raw XML file, and not the processed result. Which makes sense (I guess, otherwise that could be pretty annoying in other cases). My question is, how do I, preferably from GWT, have the browser's native XSLT processor do its magic and then get the result to inject it? Any ideas or suggestions? In the meantime, because I didn't find anything to do this so far (but I might have missed it in the docs), I was thinking of improting ajaxslt-0.8.1 [1] in my GWT module and call it using JSNI, as it seems it is powerful enough to process my stylesheets. (but I would have to modify both the stylesheets and the XML files to remove the declarations, or maybe remove them dynamically) Another possibility was to use Johann Burkard's excellent "xslt.js" [2] library, which wraps the native XSLT processor of the browser, but I would have preferred a more "GWT-only" solution, in case there's already one.

SOP and linker cross-site
I have spent a lot of time on this, and gotten myself totally confused. At this point I'm not even sure how to clearly frame the question! Let me try this: With Eclipse, and the Google plug in, I create the simple "greeter" example. Now, I deploy on Google AppEngine (Java). All goes well. Now I want to create an HTML page on a totally unrelated domain and have the greeter application run on this page. 1. we add the to module.gwt.xml 2. we change the relative address of the nocache.js to absolute like: src="http://location-app.appspot.com/jplocation/jplocation.nocache.js"; All is well, except that the RPC fails, presumably because it can't find the location of the servlet. Perhaps I need to be looking at web.xml and tweaking the url-pattern? However, when deploying to AppEngine, it's pretty fussy about what goes in as url-pattern. Assuming there is some way of doing what I want, how do I hook up with the servlet? Again, hopefully this is helpful: we use a totally standard Google Plugin New Application Builder, only the cross-site link statement added, and only the one change on the html host page (don't care about css at this point). If you can throw any light on what I'm missing, I would appreciate it. John --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Will GWT meet my needs?
Oops! Sorry for the double reply. I thought the first one hadn't gone through. I think I've found what the problem is with what I was doing..it seems GWT isn't designed to be added dynamically to a page after the fact. A blog post here alludes to the problem: http://www.pathf.com/blogs/2007/08/bjax-a-quick-ha/ The fix there worked with GWT 1.4, but I've hacked through my own nocache.hs to make similar changes, and now it appears to be loaded properly to my pages 'after the fact', after onLoad's already fired etc. I do wonder if this is 'safe' though? Does GWT make other assumptions that would make it dangerous to dynamically add it to a page after the initial page load, or am I OK?

Re: Will GWT meet my needs?
Hey Ian, Thanks very much for your reply. I don't absolutely need the widget-y stuff, no.. I gave this a quick bash to see if I could get something working quickly. I have a simple GWT app that should add a button to the end of the page it loads in. It works OK in a test page on my machine, loading the .js file from a remote server (I have compiled it for cross site access). However when I get a firefox extension to embed the script in a page on page load, it seems to lock up the page.. it'll load the right page initially, but then it 'redirects', almost, to a blank page and loads i perpetually. Not sure if there's a quick and easy answer to that question, maybe there's more configuration that needs doing in order to allow a gwt app to be dynamically added to an arbitrary page (?)

Re: Will GWT meet my needs?
Hey Ian. Thanks for your reply :) I don't absolutely need the widget stuff, no.. FWIW, I just tried out a very naive first attempt with a simple gwt app that just adds a button to the end of the page. I compiled it for cross-site access ( in the .gwt.xml file), and embedding it in a test page on my computer, it seemed to work. But now, getting a firefox extension to add it to the page on a page load..the page just spins forever on a blank page. It'll momentarily load the right page, then 'redirect', almost, and show a blank page that's perpetually loading.. Not sure if there's a quick and easy answer to that one! Maybe I've missed another thing you have to do for embedding a gwt app into a page not hosted on the same domain.

Re: Will GWT meet my needs?
I think it depends on what you're doing when you "modify the page". As of GWT 1.5 (the last version I've used personally), it's difficult to construct a Widget around an existing DOM element. On the other hand, if you don't need GWT's Widget API, then GWT is exactly what you need. Some people are confused by GWT's offering, but it's really important to remember that it's a very modular tool. The only thing you need to have in order to say you're "using GWT" is the GWT compiler. The download also includes various modules for doing things in a web page, though, that make your life easier. At the very bottom is the DOM API that mirrors the browser's DOM API into Java. There's also a module for doing AJAXy stuff, and an RPC-over-HTTP module that's built on top of that. If it suits you, you can use the Widget API, but it's not necessary. Ian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Will GWT meet my needs?
Hi there, I'd appreciate any advice on this. I currently have a javascript application that serves as the base of extensions for various browsers, for a service I run. Basically the extensions pull this javascript into whatever webpage the user loads, and the javascript does some stuff with the webpage, and so on, making calls to a server (hosted on AppEngine :)), sending it data and retrieving json (getting around Javascript's same origin policy to do this. The Javascript may be embedded into, say, cnn.com and making calls to my appengine hosted backend). I'm wondering..could I replace my Javascript with a GWT-compiled Javascript file in this scenario? I'm not sure if the nature of GWT deployment would preclude me from embedding a GWT JS file in arbitrary webpages..? I'm sort of tempted by the idea of having 'google optimised' javascript code for my app, and benefiting from GWT's other features and community, but I'm not sure if this is really feasible.. Can anyone say if my scenario is suitable for GWT or not?

Frame.setURL in IE6/7 always cause's refresh of contents? (even if just the #token changed)
Ive notice that, under IE browsers (-sigh-) that setting a frames Url
always seems to cause the whole frames contents to refresh, even if
its only the history token thats changed;
eg.
Frame.setURL("www.existingurl.com#old")
..
Frame.setURL("www.existingurl.com#new")
Firefox and Opera neatly change the token of the Frames url without
refreshing its contents.
Is this intended? Any work arounds?
I tried using setPropertyString and setAttribute to directly change
the url of the Frames element, but that didnt help. (in fact it made
it worse...Firefox and Opera both refreshed the contents completely
too).

Re: Validation problem
Try

You can amend the regular expression to validate pretty much anything

Re: Handling focus/change events on composite widgets
Ah, I get it now. Have a timer. Start the timer when either box onBlurs. A few ms will do (25?) - you'll have to test, but even quite large delays (500ms) might be acceptable. Cancel the timer if either box gets focus The timer validates the boxes when it runs. It doesn't really matter whether the text has changed or not since the validation is not time consuming. OR Have one box and validate for acceptable strings - 1' 2" or 1ft 2in etc Ian http://examples.roughian.com 2009/5/27 retro > > Hi Ian, > Sorry for being vague.

Re: Problem with using History tokens and Frames in IE (very basic code included)
Ok, an update on progress in case anyone finds it usefull;
The above overkill method does work;
If the HTML is loaded as part of the main DOM, gwt hyperlinks changing
the history token wont refresh the page anymore in IE.
If anyone else's use's this message, I'd suggest only using it for IE,
and to put a message up blaming the users choice of browser for the
extra second or two loading time.

Re: Handling focus/change events on composite widgets
Hi Ian, Sorry for being vague. The use case is having a item height widget with separate boxes for height in feet and one for inches. I need to be able to fire validation on this box as a whole when one of the box changes but only if the focus is not in the other boxes, so this logically needs to behave as one box for focus lost events. This could be true for another use case as well where widget has 3 textboxes but they need to fire focus lost as one when some boxes value changes, but not if user is still focused on the other two boxes. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT design question
I do this type of thing also. For us it comes down to packing the deployments correctly. We have multiple client applications in the same gwt project (we use eclipse). We then have a gwt xml file for each. During our build process we build each of the applications separately and the last step of the process creates a war with the client apps and server classes. We then have different html entry pages for each app. If you want 1 entry page,the other option is to use deferred binding and use a different main module with the entry point for each different platform. One for desktop browsers (the default one) and a different one for the iPhone which would then be overriden in the gwt.xml. Since I haven't done this before, I'm not sure if the entry point can be replaced, but it should be possible - even if all the main entry point does is call another class that can be deferred bound.

On the Desktop-Page the user has the full functionality of my webapp. But on the iPhone he should only be able to use certain functions due to simpler navigation. Both pages use the same business logic on the server. Only the view is different. I thought of this approach: If the user comes from a desktop my initial servlet will dispatch him to the desktop version of my site If the user comes from an iphon my initial servlet will dispatch him to the iphone page The problem: i do not want to combine the iphone version and the desktop version since then the user would have to load both apps although he would only use one part at a time. Therefore i want to split up both parts. What is the best approach for this? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Wierd errors when trying to test GWT app in IE 7.0
Hi, I am working on a database driven GWT application. In my application I have a Multi Column Tree control which again is populated by db values and it allows user edits also. I have used Smart GWT in my application to create the Multi-Column tree. My application runs fine when I run it in hosted mode but when I try running it in IE (by using Compile/Browse) button it the following compile errors : [ERROR] The type com.google.gwt.dev.js.rhino.ObjToIntMap$Iterator cannot be resolved. It is indirectly referenced from required .class files [ERROR] An internal compiler exception occurred com.google.gwt.dev.jjs.InternalCompilerException: Failed to get JNode at com.google.gwt.dev.jjs.impl.TypeMap.get(TypeMap.java:75) at com.google.gwt.dev.jjs.impl.BuildTypeMap $BuildDeclMapVisitor.createParameter(BuildTypeMap.java:392) at com.google.gwt.dev.jjs.impl.BuildTypeMap $BuildDeclMapVisitor.mapParameters(BuildTypeMap.java:514) at com.google.gwt.dev.jjs.impl.BuildTypeMap$BuildDeclMapVisitor.visit (BuildTypeMap.java:314) Could you please help me out in resolving these issues ? I want to deploy my application but due to these errors I am not to proceed. Please help me.

Re: Hibernate and GWT - location for hibernate xml mapping files under a GWT project - org.hibernate.MappingNotFoundException
Do not put the file anywhere inside WEB-INF directory. Put it inside the root directory of your class path. i.e. say you are modifying the sample Guestbook application. then put it just inside the src directory like. src hibernate.cfg.xml GuestBook GuestBook.client GuestBook.server war WEB-INF classes lib web.xml GuestBook.css GuestBook.html The compilation unit automatically place it under war/WEB-INF directory wherever it would need to be.

Re: Is there a Java URL encoder class that can be used in both Java/Javascript?

Just a note on URLEncoder/URLDecoder, keep in mind that they are only equivalents of the encodeURIComponent/decodeURIComponent JS methods; *not* encodeURI/decodeURI. I've seen (reported, actually) this error in Alfresco (and their might be many other apps out there with this same issue), where it causes problems with "+"s: https://issues.alfresco.com/jira/browse/ETWOTWO-1153 (the workaround was to use a servlet-filter to replace "+" with "%2B" in all but the query-string part of the request URL) > Does anyone know if a Java class out there on the web that implements > a good-enough URL encoding/decoding mechanism and which does not > depend on any disallowed classes? I'd go the same way as Ian said; or maybe rather take advantage of in GWT: instead of using an interface, make a class that does the "Java" thing; and in a , re-implement that class deferring to com.google.gwt.http.client.URL) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: AJAX app stuck when running Selenium RC
Not sure if this is the same issue but Selenium has a clash with GWT that causes certain operations to "freeze" (namely RPC calls after clicks). The answer was to compile with Obfuscated mode (-style OBF). The issues is reported here: http://code.google.com/p/google-web-toolkit/issues/detail?id=2861 At the very least it proves that Selenium does indeed disrupt the application execution.
