Re: SecureRemoteService and Servlet. The battle against XSRF.
Hey everyone, thanks for the big replies. There is a lot of info in there, but I still have some questions. I understand that Mallory will always be a problem and that Eve might be one, however, defeating them is not part of what I want to do. The only thing I want to guard against are XSRF attacks. I understand that to prevent these I must put some identifier (let's use sessionID) and store it in a cookie to survive browser reload and I must pass it inside my GWT RPC request and not rely on the cookie in the header. So far so good, this is exactly what I am implementing right now. Gregor suggested that I create an interface that would extend the RemoteService, this is along the lines of what I was thinking as it would make the whole XSRF system transparent to the programmer, I have also understood from the later posts between you and Reinier that the visibility of the actual sessionID on the wire is not a problem here, so is there any substantial objection to use this approach? Shawn suggested I use his implementation with JSON, however, I have read the readme and the fact that exceptions are not thrown over the line is too big of a drawback for me as I use these in the app already. Reiner, you really seem to know your stuff, thank you for your clarifying posts and your enjoyable cynical take on the world. I think I understand what you are saying. Last question, would using SSL (which will be implemented on the server within a week or two) also prevent XSRF? From what I have read, I cannot draw a conclusion one way or the other.

Re: Remember user information
The only way to remember user information in the browser between reloads is to use cookies. However, be VERY carefull about what you store there as these are sent over the wire with every request aswell as headers. There is one other way, and that is to allow the browser to store them. To do this, you have to put the username and pass textboxes into a div that will load normally in the HTML. This allow the browser to recognize them and store the info in it's own way. When you need someone to log in, you simply set it to visible, and when you don't need it you can make it invisible with one call.

Re: Is Run Time Annotation Possible?
You can have a look the Wiki page :
http://code.google.com/p/gwt-ent/wiki/UseReflection
need include GWT-ENT module into your project.
then include "Reflection" flag interface into your class
ClassType classType = TypeOracle.Instance.getClassType
(YourClass.class);
done :)

Re: SecureRemoteService and Servlet. The battle against XSRF.
Your plan to use an interface extending RemoteService to be consistent
in how you read the sessionID out of the request body and not the
cookie sounds excellent.
SSL does not protect against XSRF by itself. However, it does turn
moot the general issue of having session IDs hit the line. The long
talks about attempting to hide the sessionID by hiding the cookie and
using some whacky crypto scheme are experimental craziness without
SSL, and if you're already using SSL, utterly pointless.
In other words, SSL + your XSRF protection plan = security sweetness.
I run my website that way. (tipit.to)
You could hack in some sort of exception-over-JSON protocol, where you
build a custom class in between the HttpServlet and YourOwnServlets
class inheritance, which makes it easier to output JSON (for example
by allowing you to output a hashmap), as well as wrapping the actual
doGet()/doPost() calls (by overriding service()) in try/catch, and
having a standard way of conveying the exception to the client. e.g:
{ "error": true, "errorType": "java.io.FileNotFoundException",
"errorMessage": "/foo/bar" }
Going JSON with your API isn't really "better" than using GWT-RPC
unless you have very specific needs (such as: I'll be accessing my
servlets from something other than GWT as well), so only do this if
you really really need it.
One last security note on tossing exceptions across the line
automatically: That can be a security leak, in the sense that you tend
not to think about the exception when considering the type of data
that a servlet will send out onto the internet. It's rare that useful
info leaks out that way, but it does happen, and often it helps a
cracker determine fruitful attacks. Unless you run a very security-
sensitive app, I would accept the risk, but think about what info
might be available in an exception, and if its really bad, do
something about it. Example:
You need to read the password to the database off of disk, because you
use some horribly outdated database layer. The filename contains the
name of the db server and db name. This is info a cracker didn't have
before, but if that file doesn't exist or can't be read, now he does,
because FileNotFoundException, IIRC, has as message the filename. So,
the cracker sees /dbPasswords/localhost_1234_myServerDB or some such.
More info than he had. If he's found a different app on your site that
can be coerced into returning any given file anywhere on the system,
but not directory listings, he now has his puzzle complete and knows
the location of your db and the password. Again - don't abandon the
idea of swapping exceptions across the wire, just try to be aware that
it happens and that exceptions thrown by your servlet is essentially
public info.
NB: Bedankt :)

Re: GWT with non-Java backend
Yes, tons of people have used GWT on the front and something that isn't java on the back-end. You can transfer data using JSON, XML (but, really, don't. XML is stupid as a wire protocol), or whatever binary format you think is useful. The only caveat (and this applies to using GWT-RPC as well), is that GWT apps can only receive data 'whole'. You can not stream. So, if you were thinking of pumping 50 megabytes worth of data down to the client, you need to split it up into pieces and have the GWT client app request and process each piece one at a time. The general idea of processing 50 MB worth of stuff in a javascript app also doesn't sound like a good idea in general, as javascript isn't really fast enough to do it unless you're on WebKit+SquirrelFish, Google Chrome+V8, or Firefox 3.1 beta + tracemonkey. (Those are all beta or small market share browsers with amazing javascript interpreters).

Hi @all, is there an easy way to upload or download some data from a users computer to a form?

I have 2 questions: - Is this possible with Google Web Toolkit? - Is this possible without sending the data to the server and then to download the xml-file? Many thanks!

Re: @EJB annotation during junit testing doesn't work
Hello
Thanks for your reply
The thing is when I run hosted mode everything works fine.
Hosted mode runs gwt embedded instance of tomcat, so does GWTTestCase.
This is why I believed it was connected with GWT.
Anyway, in this situation, how can I run tests in the container?

Re: SecureRemoteService and Servlet. The battle against XSRF.
Hey Reinier,
I am happy to hear that you agree with my approach so far (and even
use it yourself). Since I will only use GWT to communicate with the
app on the server I see no reason to adopt JSON, so were almost there.
Problem here is that I still need somewhere to add that sessionID into
the request from the client to the server. I have to admit that my
basic Java knowledge now seems to fail somehow here. I have attempted
to use the method suggested by Gregor earlier in this thread, however,
I can't figure it out.
>From what I can figure out about the code from Gregor one would
subclass (or subinterface I guess) the interface of the RemoteService
into the SecureRemoteService for instance. However, I do not
understand how to proceed from there.
I think I modified the example enough to show how far my knowledge
goes right now, but there are some issues with my idea: First the code
example:
--- Code, I hope this formats reasonably in the post. ---
public interface SecureRemoteService extends RemoteService {
/**
* Utility/Convenience class.
* Use SecureRemoteService.Async.getInstance() to access static
instance of IpsvRmapServiceAsync
*/
public static class Async {
private static Async ourInstance = null;
public static synchronized Async getInstance() {
if (ourInstance == null) {
ourInstance = (Async)
GWT.create(SecureRemoteService.class);
}
return ourInstance;
}
public void setServiceEntryPoint(String entryPoint) {
// This is where the magic happens.
((ServiceDefTarget) ourInstance).setServiceEntryPoint
(GWT.getModuleBaseURL() + entryPoint + "?sessionID=" + getSessionID
());
}
private String getSessionID() {
// Do stuff to get sessionID
return "SessionID";
}
}
}
--- End of code ---
>From what I can see, this should work if the interface extends the
SecureRemoteService instead of the normal one. However, to properly
create an instance of this class, the programmer now has to do
something different from the normal procedure. Instead of calling the
normal GWT.create(someService.class) and casting it to the Async
version, he has to call on GWT.create(someService.Async.class). This
means he has to modify all of his proxy creation statements as well.
Is there any way to get around this?
Thanks, Patrick

Re: SecureRemoteService and Servlet. The battle against XSRF.
Hi Patrick,
I think you probably want to call the static async instance according
to usual RPC protocol, i.e. in this case SecureRemoteServiceAsync,
otherwise you might get confused as to what's going on

Then you use it like so in code:
SecureRemoteServiceAsync async
= SecureRemoteServiceAsync.App.getInstance(); //
the URL will now have the SessionID param
async.someMethod(param, new secureRemoteServiceCallback());
Note that this does not work across the board, you have to do this
once for each RPC service separately (i.e. once per RPC service
interface declared), but if you extend RemoteServiceServlet and
override the processCall() method to grab and check sesionID
parameter, then use this extended RemoteServiceServlet this for all
your RPC services, they will all validate the sessionID.
I guess it's a matter of taste and situation, but I think I prefer the
second method (the Command pattern variation) becasue a) if you want
to change the way you handle this session thing, you just do it the
Payload base class and the extended RemoteServiceServlet.processCall
(), you do not have to change all your RPC Async interfaces and b)
this Payload pattern is useful for a lot of other reasons in handling
objects over the wire. I think it deals with the XSRF issue too (but
I'm sure Reinier will nail me to wall again if wrong!)

Re: GWT-ext or ext-GWT?
That's fine, but you also need to consider future maintenance of your application. If your application is going to have any substantial life time and going to have to be extended and maintained, you're going to have a pretty hard time with gwt ext or ext gwt. However, I know the mentality of "quick, get it out the door, I don't care that there aren't any test cases" is still very prevalent. If that's the type of work environment one is in, they have little choice. -- Arthur Kalmenson On Thu, Nov 27, 2008 at 9:57 AM, Niklas Derouche <[EMAIL PROTECTED]> wrote: > > > On Thu, Nov 27, 2008 at 2:52 PM, Arthur Kalmenson <[EMAIL PROTECTED]> > wrote: >> >> I disagree, you don't need any exotic graphic needs to use GWT.

Re: SecureRemoteService and Servlet. The battle against XSRF.
Another thing you can do in order to always send your session
identifier as part of your request is use the RequestBuilder and add
the identifier as a request header.
RequestBuilder requestBuilder = new RequestBuilder("POST", "/
myServletUrl");
RequestBuilder.setHeader("X-Session-Id", mySessionIdFromCookie);

Re: Masked Input
Hi all..
I saw GWTTiger, but this doesn't work with complex masks, then I found
jQuery Mask and Money plugins. These two have a fine-grained mask
sintax.
http://digitalbush.com/projects/masked-input-plugin/
http://inovaideia.com.br/maskInputMoney/
See what I did:
public abstract class Presenter extends Composite {
private String name;
public Presenter(String name) {
this.name = name;
initWidget(getWidget());
}
public String getName() {
return name;
}
public void maskCurrency() {
DeferredCommand.addCommand(new Command() {
public void execute() {
jQueryMaskCurrency(getWidget().getElement().getId(),
SiteManager.getNumberConstants().monetarySeparator(),
SiteManager.getNumberConstants().monetaryGroupingSeparator());
}
});
}
private native void jQueryMaskCurrency(String id, String decimal,
String thousands)/*-{
$wnd.jQuery(function($) {
$wnd.jQuery("#" + id).maskMoney
({"decimal":decimal,"thousands":thousands,showSymbol:false});
});
}-*/;
public void mask(final String mask) {
DeferredCommand.addCommand(new Command() {
public void execute() {
jQueryMask(getWidget().getElement().getId(),
mask);
}
});
}
private native void jQueryMask(String id, String mask)/*-{
$wnd.jQuery(function($) {
$wnd.jQuery("#" + id).mask(mask);
});
}-*/;
protected abstract Widget getWidget();
public abstract void setEnable(boolean enabled);
public abstract String getValue();
public abstract void setValue(String value);
}

Statement that GWT can be used to drive the UI of entire webapp is incomplete
The correct statement is that if you want to build the UI of a webapp that cannot be indexed by search engines only THEN you can use GWT to drive the entire UI. Otherwise stick to jsp, html, javascript and code it by HAND. Basically, I was in a state of rapture being able to write the kind of UI that's possible using GWT without having to bother about javascript and html. Then I realize that the thing cannot be read by search engines because they like to browse it as "text". They see what a browser like Lynx will see. Well, Lynx will see jack on my website so it means all search engines see that. So that's what I have created as far as everybody else on the internet is concerned. Ian Bambury's website at http://examples.roughian.com comes to the rescue. I can pick ideas from there and salvage my months effort. What I have to do now is create a parallel structure to my website - parallel webpages and parallel navigation. I have to use Firefox web developer extension to inspect the pages/elements I created and write code to create them BACK AGAIN by HAND so that they can be read by "Lynx". Awesome! And while doing this I expose myself to the nonsense of dealing with exposing the same content to search engines and users otherwise I get penalized for misrepresentation. Double awesome! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

I'm going to try the BulkTableRenderer today. I want to be able to catch button right click events on the row and don't see text being able to catch those and therefore made labels for each cell.

Re: SecureRemoteService and Servlet. The battle against XSRF.
Someone seems to disapprove of Reinier's views here and appears to
have awarded a "poor" rating to each of his contributions to this
thread. This is presumably calculated to deter the community from
taking what he says seriously. For my part, especially in the light of
the many other contributions he has made to this group on the subject
of security, I would comment Reinier has almost certainly forgotten
more than I have ever known about web security.
Now one thing I could do is add an excellent rating here to each of
his posts to balance things up, but that's just playing silly buggers,
isn't it. Teenage/crank YouTube stuff.
So whoever you are, why don't you state your case openly? I'd guess
Reinier himself doesn't give two hoots about this (and probably
wouldn't admit it if he did) but I do not think the community is best
served by this sort of shenanigans. For the little I myself know about
web and network security, Reinier's posts chime right in with it. If
you think he's wrong, off the wall or something, then explain - oh,
and at something even half approaching the detail.

Configuring GWT in WepSphere Application Server
Hi, I am new to GWT, Planning to repalce a good presentaion layer alone without changing any other layer into an existing web app which is developed in JSP?servlet combination. It is confusing the GWT setup into any other server, Not sure what file is required. Requesting anyone who reply steps configuring a simple GWT example in WepSphere application.

Popup center problem
Hi all,
I have a little problem with the PopupPanel. There is my class :
public class PopupImage implements ClickListener, PopupListener {
private static PopupImage singleton = null;
private PopupPanel popup = null;
private PopupPanel glass = null;
private Image image = null;
private PopupImage() {
image = new Image();
image.addStyleName("popup-image");
image.addClickListener(this);
glass = new PopupPanel(false, false);
glass.setStylePrimaryName("popup-glass");
popup = new PopupPanel(true, false);
popup.setWidget(image);
popup.addPopupListener(this);
popup.setAnimationEnabled(true);
}
public void show(String imageURL) {
image.setUrl(imageURL);
glass.show();
popup.center();
}
public void onClick(Widget widget) {
popup.hide();
glass.hide();
}
public void onPopupClosed(PopupPanel popup, boolean autoClosed) {
if (autoClosed) {
glass.hide();
}
}
public static PopupImage getInstance() {
if (singleton == null) {
singleton = new PopupImage();
}
return singleton;
}
}
As you can see the only way to use this class is to call :
PopupImage.getInstance().show("anImageURL");
So when I use it, on the first call neither the animation nor the
center method works. Indeed the image appear directly and not on the
center.
But when I recall the show method then all works correctly only if I
use the same url, e.g the same image size's.
I thought the problem was that my popup doesn't know the size of the
image before showing it, and I tried to fiw this by many ways but I
failed each time :'-( .
Someone have an idea ?
Thx.
Regards,
Rimimi

Re: Statement that GWT can be used to drive the UI of entire webapp is incomplete
I'm not sure where you are going with this, but I will state that GWT's "issue" about not being indexed by search engines is hardly unique to GWT. All Ajax apps that reside on the web and dynamically produce their UI components, and shove that content into a single (or minimal) amount of pages have this issue. Site map xml and other SEO techniques are needed on any Ajax app...GWT or otherwise.

Re: How to upload xml file with out writting servlet in the server side (using RPC call)
I believe the only way you're going to easily upload a file to a webserver is using servlets. You "could" move the XML content up to the server via an RPC call, and then on the server writing a new file to the server filesystem and stuffing the content into this new file. The problem that I can see is that if you want to have the user just point to a file on their local machine, you will have to do some serious magic to get that dragged into the web browser space. Again, fileupload and using servlets would be way easier in my opinion Why are you opposed to servlets, if I may be so bold to ask?

Re: Popup center problem
you need to set the size of your popup before you show/center it.
glass.setSize("300","300");

Re: How do I separate static files?
But gregor.. The problem is with my GWT configuration... Look... I've already configurated IIS and JBoss. They are working together. So.. I've splited the Applicatoin in static and dinamic. The static is on IIS (www folder), and can be acessed on http://apl/ The dinamic is a war file on JBoss and can be acessed on http://apl/Apl So... I acess http://apl/index.html that has an GWT interface, and use a RPC (the remote service module is called "Ctrl") So... Ctrl is provided by JBoss, on http://apl/Apl/Ctrl But, when I try to execute RPC, It returns an 404 error, on exception com.google.gwt.user.client.rpc.StatusCodeException. I belive I need to do something to say that the url isn't http://apl/Ctrl. The right is http://apl/Apl/Ctrl. I think this config is on GWT application. But I don't know what I have to do.

Re: How do I separate static files?
The simplest thing to do would be to put your module files in your war, that way the module and your service implementation are in the same context, and you can do GWT.getModuleBaseURL()+"Ctrl"; to build your url. by placing your gwt files in IIS (using the paths you supplied) you'd have to do GWT.getModuleBaseURL()+"Apl/Ctrl"; -jason On Dec 1, 2008, at 11:43 AM, thitoh wrote: > > But gregor..

removing attributes from FlexTables
Hi,
I am running gwt-1.5.3 under linux and java-1.6.something.
I have just gone through the following exercise. I created a
FlexTable, added content and then was messing with the styling for the
table. I decided that the default "styl" for FlexTables was not
helping me so I wanted to remove it. The default styling includes
"cellpadding", "cellspacing", and a ''style="width:100%; height:
100%;"'' string.
I tried:
Flextable body = new FlexTable();
body.setText(0, 0, "");
body.setStyleName("body");
body.getElement().removeAttribute("style");
body.getElement().removeAttribute("cellpadding");
body.getElement().removeAttribute("cellspacing");
but nothing changed. I found a thread on a slightly different topic
here that used something like:
DOM.removeElementAttribute(body.getElement(), "style");
DOM.removeElementAttribute(body.getElement(), "cellpadding");
DOM.removeElementAttribute(body.getElement(), "cellspacing");
This has worked. I don't know what the difference really is but FYI
in case it is useful.

Lazy Loading (Tier 2 GWT Roadmap) - Status update
I'm sorta directing this to the GWT developers but... all input is
welcome.
The GWT Roadmap identifies "lazy loading" as a Tier 2 priority ("more
complex but important"). As of today, it is the only tier to item
that is not already "done" or at least "in progress".
This is something my project could really use. Is there any kinda
estimate that can be made as to when and if this might be started and/
or available?
Lazy loading has been mentioned here and there in other topics, but
I'm asking in the context of the roadmap item.
Our project demonstrates a fairly common scenario where lazy-loading
might be used. We have an application composed of many small-to-middle-
sized modules.At the moment, we have little choice but to load all
modules which is (now) somewhat large.
Thanks

Reinier, Why do you advocate rewriting your web stack's session management when you could just as easily let it continue to use the cookie as long as you validate that it matches the sessionid passed up via the parameter list? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Lazy Loading (Tier 2 GWT Roadmap) - Status update
...and runAsync() is already in the trunk if you are comfortable
building from there (http://code.google.com/webtoolkit/
makinggwtbetter.html#workingoncode).
I use it in a similar situation to what you describe and see good
results. My usage so far is along the following lines:
GWT.runAsync(new RunAsyncCallback() {
public void onFailure(Throwable caught) {}
public void onSuccess() {
cssEffectTester.init();
}
});
where the code associated with cssEffectTester.init() becomes a new
download.
I'm sure better/other patterns will come out as time progresses.
There's another approach here:

Re: Statement that GWT can be used to drive the UI of entire webapp is incomplete
The thing is this - there are individual URLs and there are backend calls. You can browse to those URLs but you can't do a GET on them. Entire content is delivered in those backend calls in JSON which gets displayed by the web page. That's the content that should be indexed. Search engines won't make this association between URL and the backend calls, they want text. So for their benefit I have to dump those contents into an html page and thereby open a whole new pandora's box. That's the page they will oblige me by indexing and by directing users to. Then I do a redirect and send the users to a sensible web page. This is broken. I should never have attempted this. All this treachery about redirect/forward was what I wanted to get away from. But I couldn't. I didn't want to end up coding html and javascript by hand but now I have to. All over. From start to finish. This is not about optimization, this is about feasibility. I do not want a search engine optimized website. I do not want a good ranking. I want the poorest ranking. I just want the thing to get *indexed*. But I am going to have to write html and javascript by *hand* to do that.

History and Frames
Hi, I have a simple test page: top widget is just an image, bottom widget is a Frame. I have a History listener setup which simply does "Window.alert (token)" whenever the history changes. If I add a link to the top of the page and click on it, then I get the window alert so I know that the history listener is setup and working. However, if I fill the frame widget with a web page, then in that page click on a link, I don't get any history alerts. The api docs for Frame state: "Note that if you are using History, any browser history items generated by the Frame will interleave with your application's history." To me that means that I should be getting history events in my listener for links that are clicked on in a Frame widget, but I don't get them. I am using GWT 1.5.3 on linux. Does anybody have any tips / tricks/ docs to correct this?

Re: SecureRemoteService and Servlet. The battle against XSRF.
Hmm.. I ve a stupid question now..
Can't we use RemoteServiceServlet.getThreadLocalRequest().getSession()
to get the current session?
I found 'using the session' working in GWT 1.5.

Re: Statement that GWT can be used to drive the UI of entire webapp is incomplete
But again I repeat: your beef is with AJAX as a whole. GWT doesn't make the issue you've described better or worse. It is endemic of all AJAX based technologies. That's my only point on the topic.

Re: For what this files?
Hi rov.ciso, I'm not very familiar with GWT-Ext, but I imagine the generated output consists of the CSS file containing the styles applied in your application and the JavaScript files necessary to realize the application itself. Similar to the standard GWT application bootstrap model, you probably need to include an emitted .nocache.js file generated in the js directory in your host HTML page to load up your GWT application. It's possible that the bootstrap procedure and load up convention differ in GWT-Ext, in which case I recommend posting up about the problem on the GWT-Ext forums (link below).

Re: Problem with the import java.security.*;
Hi Phani,
I can confirm that the java.security package is not supported in GWT.
Keep in mind that GWT is for Ajax application development on the
client-side, so all code gets cross-compiled from Java to obfuscated and
optimized JavaScript that can run in the browser. Therefore, you are bound
by the same browser limitations as any other Ajax framework, hence
java.security functionality not being available on the client.
What you could do to solve the unique number generation problem in the code
snippet above is have it run on the server and pass back the number to the
client through a GWT RPC call or a RequestBuilder callback.
For more information on either technique, check out the GWT docs linked
below.
GWT Developer Guide:
http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=google-web-toolkit-doc-1-5
Hope that helps,
-Sumit Chandel

GWT DateTimeFormat Bug?
I am using the com.google.gwt.i18n.client.DateTimeFormat.parse method
to parse data from thmy RSS feed. I am having a problem because we
want all of our RSS feed dates to be in GMT-00:00 and it is throwing
an error when my current time zone(GMT-07:00) is on Dec 01 and the
dateTime it is parsing is on Dec 02. An example of the code is as
follows:
DateTimeFormat dtf = DateTimeFormat.getFormat("EEE, dd MMM
HH:mm:ss ");
pubDate = dtf.parse(node.getFirstChild().getNodeValue().replace("GMT",
"GMT-00:00").replace("Z", "GMT-00:00"));
java.lang.IllegalArgumentException: Tue, 02 Dec 2008 06:24:49
GMT-00:00
at com.google.gwt.i18n.client.DateTimeFormat.parse
(DateTimeFormat.java:1120)
at com.google.gwt.i18n.client.DateTimeFormat.parse
(DateTimeFormat.java:601)
Which should parse to Mon, 01 Dec 2008 11:24:49 GMT-07:00
Also, can anyone tell me why GMT, Z or UTC are not in the time zone
abbreviations?

Re: Compilation Problem
Hi Sandile, Are you running into compiler problems as a result of a recent upgrade to GWT 1.5.3? If not, can you try compiling the sample applications in the GWT distribution to see if those work? I'm not able to reproduce the problem here, so we'll have to narrow it down to what's happening on your end. It could either be a forgotten step while upgrading to 1.5.3 or incorrect code that isn't behaving like you expected.

Re: Compilation Problem
Hi Rahul, When editing your sources in Eclipse, do you first refresh the hosted mode browser before hitting Compile / Browse, or go straight to Compile / Browse? If you are skipping the refresh step, it's possible that that's what responsible for the NullPointerException you're encountering. In fact, I've reproduced a similar error on my side by doing just that. However, it does seem like the right thing that should take place would be the hosted mode console warning the user that they didn't refresh, or better still have hosted mode perform an implicit refresh when necessary. We should create an issue report to track this problem. Feel free to create a new report on the Issue Tracker (link below): http://code.google.com/p/google-web-toolkit/issues/list Hope that helps, -Sumit Chandel On Sat, Nov 29, 2008 at 6:14 PM, rahul <[EMAIL PROTECTED]> wrote: > > I am seeing the same issue with 1.5.3. > > I am seeing a NullPointerException when I edit my app sources in > Eclipse and use the Compile/Browse option in the Hosted browser. > > Rahul > > > On Nov 28, 12:16 pm, Sandile <[EMAIL PROTECTED]> wrote: > > I get an error every time that I try to compile my code: > > > > [ERROR] Errors in 'jar:file:/C:/dev/gwt-windows-1.5.3/gwt- > > windows-1.5.3/gwt-dev-windows.jar!/com/google/gwt/dev/jjs/intrinsic/ > > com/google/gwt/lang/Stats.java' > > > > [ERROR] Missing message: compilation_internalError in: > > org.eclipse.jdt.internal.compiler.messages > > java.lang.NullPointerException > > > > at com.google.gwt.dev.javac.JdtCompiler > > $CompilationUnitAdapter.getContents(JdtCompiler.java:65) > > > > at > org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java: > > 9236) > > > > at > org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java: > > 9208) > > > > at org.eclipse.jdt.internal.compiler.parser.Parser.dietParse > > (Parser.java:7864) > > > > at > org.eclipse.jdt.internal.compiler.Compiler.internalBeginToCompile > > (Compiler.java:587) > > > > at org.eclipse.jdt.internal.compiler.Compiler.beginToCompile > > (Compiler.java:357) > > > > at > org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java: > > 371) > > > > at com.google.gwt.dev.jdt.AbstractCompiler$CompilerImpl.compile > > (AbstractCompiler.java:84) > > > > at com.google.gwt.dev.jdt.AbstractCompiler$CompilerImpl.compile > > (AbstractCompiler.java:180) > > > > at > com.google.gwt.dev.jdt.AbstractCompiler$CompilerImpl.access$400 > > (AbstractCompiler.java:70) > > > > at com.google.gwt.dev.jdt.AbstractCompiler.compile > > (AbstractCompiler.java:493) > > > > at > > > com.google.gwt.dev.jdt.WebModeCompilerFrontEnd.getCompilationUnitDeclaratio > ns > > (WebModeCompilerFrontEnd.java:73) > > > > at com.google.gwt.dev.jjs.JavaToJavaScriptCompiler. > > (JavaToJavaScriptCompiler.java:277) > > > > at com.google.gwt.dev.GWTCompiler.distill(GWTCompiler.java:353) > > > > at com.google.gwt.dev.GWTShell.compile(GWTShell.java:639) > > > > at com.google.gwt.dev.GWTShell$BrowserWidgetHostImpl.compile > > (GWTShell.java:220) > > > > [ERROR] java.lang.NullPointerException > > java.lang.NullPointerException: null > > at com.google.gwt.dev.javac.JdtCompiler > > $CompilationUnitAdapter.getContents(JdtCompiler.java:65) > > at > org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java: > > 9236) > > at > org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java: > > 9208) > > at org.eclipse.jdt.internal.compiler.parser.Parser.dietParse > > (Parser.java:7864) > > at > org.eclipse.jdt.internal.compiler.Compiler.internalBeginToCompile > > (Compiler.java:587) > > at org.eclipse.jdt.internal.compiler.Compiler.beginToCompile > > (Compiler.java:357) > > at > org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java: > > 371) > > at com.google.gwt.dev.jdt.AbstractCompiler$CompilerImpl.compile > > (AbstractCompiler.java:84) > > at com.google.gwt.dev.jdt.AbstractCompiler$CompilerImpl.compile > > (AbstractCompiler.java:180) > > at > com.google.gwt.dev.jdt.AbstractCompiler$CompilerImpl.access$400 > > (AbstractCompiler.java:70) > > at com.google.gwt.dev.jdt.AbstractCompiler.compile > > (AbstractCompiler.java:493) > > at > > > com.google.gwt.dev.jdt.WebModeCompilerFrontEnd.getCompilationUnitDeclaratio > ns > > (WebModeCompilerFrontEnd.java:73) > > at com.google.gwt.dev.jjs.JavaToJavaScriptCompiler. > > (JavaToJavaScriptCompiler.java:277) > > at com.google.gwt.dev.GWTCompiler.distill(GWTCompiler.java:353) > > at com.google.gwt.dev.GWTShell.compile(GWTShell.java:639) > > at com.google.gwt.dev.GWTShell$BrowserWidgetHostImpl.compile > > (GWTShell.java:220) > > at com.google.gwt.dev.GWTShell$BrowserWidgetHostImpl.compile > > (GWTShell.java:227) > > at com.google.gwt.dev.shell.Brows
Re: TextArea cannot be resolved to a type
Hi Moe,
In addition to Reinier's suggestions, you could also try using JSONP or a
mashup service depending on how much control you have over the servers
hosting the external URLs that you are requesting from.
You can read more about the technique on Dan Morrill's article on the
subject (link below), which I've personally been meaning to update. If you
have access to the external server that you want to interoperate with, you
could potentially create a mashup service that your main application could
use through the JSONP technique.
"Using GWT for JSON Mashups":
http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=Article_UsingGWTForJSONMashups

Re: FileUpload and Chrome
Hi Michel,
It seems like this is a problem specific to Google Chrome (see Issue #1269
or search for others like it on the Chromium Issue Tracker). One way to make
sure is to test out your FileUpload widget in Safari to make sure this isn't
a more fundamental problem (unlikely).
Issue #1269:
http://code.google.com/p/chromium/issues/detail?id=1269
I would recommend starring the issue to keep an eye out for updates and
fixes.
Hope that helps,

getThreadLocalRequest() is returning Null request
Hello All, I have one servlet for login, which sets the session id in cookies, then I have different services to be called after user is logged in. I have one service which gets user preferences another service which gets all the products which a user would like to buy etc. When I try to validate the session against first service (getUserPrefrences) by this String sessionId = this.getThreadLocalRequest().getSession().getId(); I get a sessionId do the validation on it and everything works fine, when I try calling another service (getProducts) getThreadLocalRequest () returns null request and I get a null pointer exception. Can someone please help me with this. Thanks for all the help and support. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: javascript error getBoxObjectFor ?
Hi Ed, I haven't seen too many posts about Selenium testing going wrong in GWT, but from the issue report linked in the thread you mentioned above it seems that developers who are writing Selenium tests and using GWT RPC would have experienced the issue described therein. According to the issue, however, the workaround was to use the -style PRETTY or DETAILED flag when running the compiler, but it seems like that isn't working in your case. In fact, it seems that the issue you're experiencing has a different root cause all together (please correct me if I'm wrong). In the output you pasted above, the line: "function BBc(a)" leads me to believe that this is obfuscated code that is breaking when running the Selenium tests. When you mentioned that using -style PRETTY didn't work, do you mean that the error message still contained the garbled "function BBc(a)" or that it was just the same error again? If it is the latter, the output should be more humanly readable and I should be able to infer a bit more about where this code is being called. As it is, I'm not sure I have enough info to pass along to figure out what's going on. Please let me know if you were able to get -PRETTY output and an error message with meaningful function and variable names. Hope that helps, -Sumit Chandel In your case, however, it seems like the issue has a different root cause (please correct me if I'm wrong).
