Upload request cancelled

I am trying to upload files using FormPanel and FileUpload. The moment the I submit the form, I see this in the network console:

The request does go to server though and completes successfully but the browser receives no response and my FormPanel.SubmitCompleteHandler is not executed. Any idea why this could be happening?

It does work sometimes though and once it works, it does not fail thereafter.

Thanks,

Tushar

Re: With ie9 I get: XMLParserImplIE6 Could not find appropriate version of DOMDocument ?

Thanks for the insight @Jens.

Re: java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor

Ok. Is this something that has changed between gwt 2.7 and 2.8? Is there a reason it is not a dependency already?

Thanks.

Re: With ie9 I get: XMLParserImplIE6 Could not find appropriate version of DOMDocument ?

IE 8 and IE 9 are using the IE6 implementation of XMLParserImpl. For some reasons this implementation fails to create a document using:

private static native JavaScriptObject selectDOMDocumentVersion() /*-{
 try { return new ActiveXObject("Msxml2.DOMDocument"); } catch (e) { }
 try { return new ActiveXObject("MSXML.DOMDocument"); } catch (e) { }
 try { return new ActiveXObject("MSXML3.DOMDocument"); } catch (e) { }
 try { return new ActiveXObject("Microsoft.XmlDom"); } catch (e) { }
 try { return new ActiveXObject("Microsoft.DOMDocument"); } catch (e) { }

 throw new Error("XMLParserImplIE6.createDocumentImpl: Could not find appropriate version of DOMDocument.");
}-*/;

Maybe the IE9 user that produced the exception has disabled ActiveX in the browser?

With ie9 I get: XMLParserImplIE6 Could not find appropriate version of DOMDocument ?

I see somebody starting the site leuker.nl with ie9 that does get the following exception:

--------------

The user agent: user-agent=Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)}

Why do I get this IE6 error (using gwt 2.7.0) when IE9 is used ? And how to solve it?

Re: What are the latest browser supported by GWT 2.6 (MOZILA,CHROME,IE)

I guess you could try searching the GWT issues to figure that out. Generally GWT only has minimum browser requirements as it assumes that future versions of existing browsers should generally not break existing GWT apps. Sometimes they do, then GWT gets a bug fix.

Generally IE 11 might cause some trouble because it has a User-Agent string that causes GWT to choose the Gecko/FireFox permutation. Could be that GWT 2.6 has some issues with that. But I am surprised that Chrome / Firefox do not work.

But maybe the issue is in your app and not in GWT, who knows. First you should try figure out why you app does not work in these browsers. There must be some sort of JavaScript exception (use browser debugger and pause on any exception) or a HTTP 404 request or similar.

Re: GWT and GA and analytics.js usage ?

Well, I didn't try to use it on the server side, but I think you'd have to isolate it as well, or use some nasty reflection stuff to get the job done.

I don't - I haven't found any. The page you posted is the most authoritative page but it refers to the old scheme (#!, ?_escaped_fragment) and I can't tell with certainty what stays true for the new scheme.

So I am thinking about using #! instead of # and see what happens, or using the History.pushState() (I not support IE 9 anyway), as I get the idea that these url's (created with the pushState()), can be indexed by Google. But I am not sure.

I don't know about pushState(). I am using GWT History.newItem(). Looks like pushState() requires some reading from my part :-).

What do you think? Are your ur's with the # fragment indexed by Google?

The point is: I am not sure. I switched to #! from # and I can't go back because the old scheme with _escaped_fragment_ is honored from LinkedIn, Google+, Facebook, Twitter and Bing so I will support nevermind what google does. FYI google crawls my pages both new style and old style - but my pages have #!

If I find anything new I will post it here.

Re: JsInterop: Casting native javascript objects in gwt

You can only implement java contract (e.g. PayLoad class) in javascript if they are marked as isNative. See the related section in the new jsinterop doc.

Once again, everything works if I use the concrete type and remove the cast.

I tried using @JsType(namespace = "acme", name = "MyJavaScriptObject"), as described in the new version of the JsInterop document, but apparently the namespace and name attributes are not there in the jar file.
Same thing with the @JsExport and @JsNamespace, I currently have to use them or things stop working.

The new annotations have a different package: jsinterop.annotations. Also @JsExport does not exist anymore in the new JsInterop version, you just use @JsType.

To activate the new annotations you also have to change the JsInterop mode via -jsInteropMode JS_RC

JsInterop JS_RC JsProperty name on method

Hi all,

Is seems like the following construction is not working when using the new JsInterop (JS_RC):

@JsProperty(name = "facets")

public Facet[] getFacetArray() { ... }

@Override // This method is defined in an interface

@JsIgnore

public List<Facet> getFacets() { ... }

The result is that the compiled property is still called facetArray.

Does anyone perhaps have any suggestions of how to work around this or why it is not working? If not, I will raise an issue in the GWT bug tracker, but I wanted to check here first.

Thanks!

I find it hard to find the exact details, often you will find the old details.

I notice in the Google Webmaster tools that the ur's with the # url fragment aren't indexed, which is also mentioned in the following article: https://www.deepcrawl.com/knowledge/best-practice/guide-to-url-design/

So I am thinking about using #! instead of # and see what happens, or using the History.pushState() (I not support IE 9 anyway), as I get the idea that these url's (created with the pushState()), can be indexed by Google. But I am not sure.

What do you think? Are your ur's with the # fragment indexed by Google?

Re: SEO Google Crawlable experience ?

I have seen this page before. Where did you see that google requires #! (vs plain #) in its new scheme?

One question is: What happens if I choose not to implement #! on my AJAX site?

Answer:

In the near term your pages may not appear properly in Google's search results pages. However, we are continously working to make Googlebot behave more like a browser. As features required by your site are implemented, Googlebot may start to index your pages properly without help. However, this AJAX crawling scheme provides a solution for sites that are already using AJAX and wish to ensure that their content is properly indexed today. We expect that it will be a good solution for anyone who already has HTML snapshots of their pages or who chooses to use a headless browser to get such HTML snapshots.

That implies that plain # will suffice in the feature. A feature that may have arrived already.

According to the last steering group meeting minutes, the release of 2.8 is only waiting for JsInterop 1.0 to be finalized. The meeting minutes say that this is expected to happen at the end of september. If this holds true you will see a release relatively shortly after that. The lack of Java 8 API emulations (java.time, streams, etc) is not considered a blocker and is expected to be provided by contributors. I have already done some work on that and together with Colin Alworth and James Nelson we plan to tackle java.time and streams. But as we will work on that in our free time, chances are that it will not be part of GWT 2.8 yet.

So with a 2.8 release the worst thing you can get is Java 8 syntax (lambdas, method references, default/static interface methods, intersection casts), stable JsInterop annotations, better SDM, lots of bug fixes. In the best case you also get some Java 8 API emulations. I guess there will be a 2.8.1 shortly after with additional Java 8 API emulations.

Also according to the meeting minutes the new GWT compiler is expected to work at the end of the year. This would then act as the base for an upcoming GWT 3.0 release.

Remove client side javascript from server

Hi Everyone,

For security reason, we don't want user be able to download client side javascript from web server. Instead, we want to package client side scripts into a chrome app (.crx) and hand it to user offline. So when visiting our web page, people who don't have this chrome app pre-installed will not work.

Is this possible? How should I configure chrome app (manifest.json) and web application (web-inf/*)?

Thanks a lot!!

I understand that you want to run everything in a single JVM (why? I can only see drawbacks, apart from "there's only one thing to launch and thus no need to remember the order you have to launch things") but that's just not a usecase GWT was designed to support. It could be made to work, and you're encouraged to come discuss this in the gwt-contrib forum and possibly send in patches, but it's low priority – plus, supporting other use cases also means making sure you don't break them moving forward, so it's not just a one-time effort, but a continuous one).

Re: SEO Google Crawlable experience ?

I just noticed that GoogleBot is coming by and resulted in an error when the site tried to perform an animation through a javascript function that isn't present.

It's because I use GreenSock animation that is loaded in the index.html, but apparently the function $wnd.TweenLite function isn't present :(...

Strange, any idea why this is ? Why isn't this created on the "Dom" when GoogleBot visits the website ?

Re: How to eliminate extra balnk column in CellBrowser

Yeah, I guess I was assuming that the last column only contains leaf values so that the right-most splitter was unnecessary, but that might not be the case in general (although in my case it is).

I now dynamically compute and set the default column width to be 1/5 of the total width of my CellBrowser. This way I don't have any empty space after the last "HDragger".

Thanks for the help.

Oh, there's no "last column", it's "empty space".
CellBrowser is given some width, then each column is created with a default width (configurable), filling empty space until they overflow and then an horizontal scrollbar appears.
BTW, I think you notice this behavior only because the last column contains only leaf values, but what if it contained both leaf and non-leaf ones?

So in your case maybe "just" configure a larger default column width?

Re: Progress bar during GWT bootstrap process?

I used GWT Lightweight Metrics in several of my projects. The progress looks real and gives some idea to a user how long he has to wait.

More info here:

http://www.gwtproject.org/doc/latest/DevGuideLightweightMetrics.html

Basically you have to put static script before nocache.js file that registers for metric events and from it updates the length of the progress bar.

Most of the time I just counted the amount of events required to show the actual app (I used a splash div with progress bar which hides the app until it's ready) including bootstrap and rpc events and used it as total amount for progress bar.

The drawback is, there are only 2 events fired when GWT loads scripts from gwt.xml. If you load big js libraries let me know so I can post a workaround for that :)

One other idea that pops to mind is the browser's developer's tools net tab to make sure that the problem is indeed in the loading of resources. Maybe you can identify a problematic resource? Or that the problem is not in the GWT script?

Otherwise I agree with Peter Donald post above for the most effective way to have a spinner/blocker element during load.

Make sure your webserver/tomcat serves compressed content.

I'd like to show a progress bar which indicates how much longer there is to go.

Worst case, I can override the Dom function for injecting a script, and use that to request the scripts over websockets, and update the progress with each frame sent.

Is that what I have to do, or is there a better way?

Like Peter and Jens said, put a loading indicator in your host html page, and remove it in onModuleLoad.

For example. Put in your html :

<h3>Launching application<BR/>Please wait....</h3>

And then in your onModuleLoad

RootPanel.getBodyElement().removeChild(DOM.getElementById("splash"));

Re: Progress bar during GWT bootstrap process?

As I said check that the content you serve is compressed.

One other idea that pops to mind is the browser's developer's tools net tab to make sure that the problem is indeed in the loading of resources. Maybe you can identify a problematic resource? Or that the problem is not in the GWT script?

Otherwise I agree with Peter Donald post above for the most effective way to have a spinner/blocker element during load.
