Re: Can't deploy to appengine with Eclipse Google Plugin 2.5 (using maven)

 Hello,

 I'm developping a gwt/gae project on eclipse indigo.
 It's a maven project.
 I'm using the google plugin, and the m2e plugin to manage the project.

 The project has a maven webapp folder : src/main/webapp
 When using the develop server, all is put by the maven plugin in the
 folder target/m2e-wtp/web-resources

 Since I upgraded to the version 2.5 of the google plugin, deploying to
 appengine isn't working anymore.
 The GWT compilation is now built in the folder target/xx-1.0-SNAPSHOT
 (created from the project info of the pom.xml)
 But data from src/main/webapp are not copied to that folder, so deploying
 failed telling me it cannot find appengine-web.xml.

 I fixed it by puting a symbolic link from target/xx-1.0-SNAPSHOT to
 target/m2e-wtp/web-resources , but it would be nice to fix this.

 Regards,

 Mathieu

Re: future of gwt who use gwt

2011-11-01 Thread David Chandler

Hi Warren,

Glad you found my SenchaCon slides (thanks, Thomas--I should have posted
them here, too). Let me put some context around fewer releases, less
overhaul. Sencha's Darrell Meyer and Sven Brunken did a huge refactoring
of Ext GWT last year to make it more compatible with mainline GWT. This was
in part necessitated by all the major changes in GWT since 2.1: Cell
widgets, Activities Places, RequestFactory / AutoBeans, etc. The GWT team
has heard from the community quite a few times please slow down and just
make it solid, and we're listening.

As to the first point (Google is heavily invested), many of Google's
largest projects are built with GWT, and it is widely used within the
company. Because GWT is open source, the community will continue to benefit
from all the work that Google does on GWT in support of our own projects.
This remains one of the great benefits of using GWT.

I apologize for the relative silence on this issue. In general, Google is
very careful about making public commitments of any kind and rarely
discusses future plans, in part because plans are subject to change.

There is no CCAT classification that I'm aware of. The incubator is not
strictly part of GWT, but would likely have the same classification as it
is also open source. There is some drag  drop support within GWT, and
there are also various 3rd party open source projects that provide drag 
drop functionality for GWT; however, Google would not have an ECCN/CCAT #
for those.

Re: Permutation, code splitting and deferred property

2011-10-04 Thread David Chandler

 /
   /none
/set-property
 
and I have a generator with the following code that generates one
implementation depending on this deferred property value:
 
public String generate( TreeLogger logger, GeneratorContext context,
String typeName ) throws UnableToCompleteException {
 String value = propertyOracle.getSelectionProperty( logger,
myProperty );
 if(value1.equals(value)){
 return generateImpl1();
 } else {
 return generateImpl2();
 }
}
 
According to my settings for each browser, you can have only one
value, ie for each permutation my generator should generate either
Impl1 or Impl2 but not both. However in my soyc report, I noticed
 that
for each browser/permutation, both implementations are generated.
 
The issue I have is that my generator generates the same GWT.runAsync
call for both implementation and since the 2 implementations are
generated for each permutation (even if only one can be used for each
permutation), GWT believes there are 2 split points and since it's
 the
same code inside the 2 split points, all the code is added to the
 left
fragment code.
 
My question is how come my generator is called twice for each
permutation? Since only one value is possible for each permutation
shouldn't it be called only once? Am I doing something wrong in my
configuration which could explain why my generator is called twice?
 
Thanks for your help,
Pierre

Re: GWT Community size ?

2011-10-03 Thread David Chandler

Hi Jonathan,

There are a couple ways to gauge this. You can see the number of times each
version of GWT is downloaded here:

http://code.google.com/p/google-web-toolkit/downloads/list

This does not include downloads from Maven Central or Google Plugin for
Eclipse, the sum of which is typically about the same as from the main
downloads page.

Also, there are 27k members of this group, which continues to grow at
~10%+/yr. Based on downloads of recent versions, this represents perhaps a
quarter of active GWT developers.

As for # of Web sites and/or businesses, we really don't know. We do know
from interacting with the community that many, if not most, GWT applications
are behind firewalls or paywalls, because GWT is especially well-suited for
making desktop-like apps that run in a browser.

RequestFactory does not provide built-in XSRF protection. You can set a

use HttpSessions. That would be a sensible default, though.

For RPC Requests I see the XsrfProtectedServiceServlet.
But I don't see a XsrfProtectedRequestFactoryServlet or similar.
While the documentation states that RequestFactory is better and newer

Does this mean it has XSRF protection included, or would one have to
rebuild what XsrfProtectedServiceServlet does for the
RequestFactoryServlet?

And why does the XsrfProtectedServiceServlet need the session cookie
name injected?
Why doesn't it simply use HttpServletRequest.getSession().getId()
which wouldn't need any manual configuration?

Re: The RequestFactory ValidationTool must be run for the RequestFactory type

Hi Eric,

Look for a class named *YourRequestFactory*DeobfuscatorBuilder in the WAR.
This will be present if the RF validation tool has run.

We're currently working on an issue where it gets wiped out in Maven
projects in Eclipse Indigo.

Is there anything else I need to do in order to convince the deployed

Re: The RequestFactory ValidationTool must be run for the RequestFactory type

2011-09-15 Thread David Chandler

Thanks, Jeff. That's some pretty fine Maven wizardry.

What we've discovered is that with the lifecycle mapping POM hacks in place,
the ValidationTool does in fact run under Indigo, but the WTP publish
operation that happens just prior to launch does not have access to the
newly-generated sources in the workspace without a refresh. We're working on
a GPE fix to address this as well as simplifying the POM by using built-in
annotation processing rather than a separate exec.

Re: Was the Lightweight Collections in GWT effort killed off?

2011-09-13 Thread David Chandler

Yes, the LWC effort was abandoned. After a lot of benchmarking, it was
determined that the GWT implementation of Java libraries perform reasonably
well, even when compared to a simple encapsulation of Javascript
datastructures. HashMap even provides specialized behavior for string keys.

The main performance gain was determined to be getting rid of boxing of
primitive types, but that had little to do with Lightweight Collections and
more to do with deeper changes to the compiler.

 Can anyone recommend the LWC code in that branch for client code as it
 stands today?

 I find myself with a UI with many instances of java.util.HashMap

Re: 2.4: Is gwt-servlet still necessary when using RF instead of RPC?

2011-09-09 Thread David Chandler

Hi Alexander,

If using RF only, you no longer need gwt-servlet, just
requestfactory-server, which is now available in Maven Central. The POM for
requestfactory-server also declares the javax.validation and json
dependencies so you no longer need them explicitly in your project POM;
however, you do need requestfactory-apt as shown in the wiki page below. You
can pull in requestfactory-server as follows:

dependency
groupIdcom.google.web.bindery/groupId
artifactIdrequestfactory-server/artifactId
version2.4.0/version
/dependency

For a working POM that puts it all together, see

http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/mobilewebapp/pom.xml

For explanation on using RequestFactory with Maven, see

Re: Does the last Google Plugin for Eclipse update install the Maven plugin too?

GPE does not install the Maven binary or Eclipse plugin (m2eclipse/m2e), but
will work with Maven projects if those dependencies are available. Beginning
with Indigo, m2e (formerly Sonatype m2eclipse) is bundled with the Eclipse
Java IDE (but not Java EE IDE), which is what you may be seeing.

Re: [gwt-contrib] maven source jars

2011-08-29 Thread David Chandler

Thanks, Daniel, it's an interesting idea toward Mavenizing GWT, but I don't
think we're ready to bite off much more than simple deployment to Central
just yet. I plan to post the current script and POMs for code review this
week. The script does a bit of custom packaging since we include Java
sources needed by the GWT compiler in the gwt-user jar itself. Let's
continue the discussion once the script is available for review.

 Hey Guys,

 I just noticed this thread, and wanted to suggest Maven Ant Tasks (
 http://maven.apache.org/ant-tasks/index.html). It includes Ant tasks for
 installing build artifacts to local Maven repositories, or deploying them to
 remote Maven repositories, both with arbitrary POMs. It can also generate
 POMs with given dependencies, and download/manage dependencies using Maven.

 It seems like a good road to take, given that it integrates better than
 tools/scripts/maven_script.sh with the existing build (Ant scripts), and
 means that you wouldn't have to store your dependencies in source control
 (apart from the patched/rebased ones, though you could deploy them to
 Central too). It could also replace your script that deploys to the remote
 Maven repository (I haven't seen that one, but I'm assuming it's a shell
 script too:
 http://code.google.com/p/google-web-toolkit/issues/detail?id=4853#c12),
 and allow you to automate the deployment to Sonatype's repo (and
 consequently to Central). If the plan was to eventually try to remove the
 dependencies and manage them with Maven, this would be a step in that
 direction too.

 Cheers,
 Daniel

 That's actually not enough though, because GWT jars are created with a
 JarIndex, and a JarIndex contains the name of the JAR, so renaming it
 without regenerating or stripping the JarIndex (META-INF/INDEX.LIST)
 generates spurious exceptions in DevMode (caught internally, but very
 annoying if you suspend executions on unhandled exceptions when launching
 DevMode with a debugger attached: the CompilingClassLoader looks up classes
 in a gwt-user.jar instead of the gwt-user-2.4-SNAPSHOT.jar).
 Removing the JarIndex, or regenerating it, is easy, but still.

Re: N-tier with RequestFactory is possible?

Hi Rafael, try the 2.4 RC (expected later today) and be sure to see

 Hi guys,

 The RequestFactory could be used for comunication between logic tier and

 It's the best choice?

 Other question: The GWT 2.4 beta avaliable for download already support
 polymorphism in RequestContext? Because a get error when add generics type

Re: GWT Developer Plugin on Safari 5.1 (OS X Lion 10.7) doesn't load

2011-07-26 Thread David Chandler

Eric,

Thank you for your investigation and for dialing down the tone a bit.
I'm pleased that the GWT team has done such a good job in the past
that you've come to expect not only a great, free toolkit, but also
updates delivered within days of new browser and OS releases. Unfortunately,
the Google instant search team hasn't yet tackled the instant dev mode
plugin problem ;-) The recent FF and Safari changes caught us by
surprise. The timing is particularly bad as lots of folks are on
summer vacation, and hiring doesn't happen overnight. Rest assured
that engineering management is aware of the plugin crisis and we are
working to address the situation; however, I cannot give you an ETA.
Please be patient.

Also, please be advised that I will be on vacation for the next couple
weeks. I will not be reading this group during that time, and very
likely no one will be responding to general GWT inquiries during that
time, although engineers will continue to chime in on specific
technical issues as always. New member moderation may also be slower
than usual. It is not typical to announce vacation on the GWT group,
but I wanted to give Thomas Broyer a message to link to in response to
any Why hasn't the GWT team responded to X threads that may emerge.
Thanks for all you do, Thomas :-)

Best,
/dmc

 Good luck, Eric :-) It likely requires non-trivial changes (which is

 It's not clear yet what'll be required.  It looks like whoever wrote
 the current plugin did a pretty decent job of separating concerns.

 What's required is a ton of work.  The current plugin is tied directly
 to the JavaScriptCore API which, as best I can tell, can't be made
 available via the NPAPI.  (if it could, the conversion would likely be
 straight forward).

 And since Safari 5.1 (WebKit2) runs plugins out-of-process, it makes
 me think that the plugin would be terribly slow... similar to Chrome's
 performance.  But that's just conjecture.

 If I had 2-3 weeks I could definitely get the plugin working, but
 alas, hacking GWT Plugins is not in my RealJob description.  Jurriaan
 Mous' workaround is good enough for now.

 And David, for what it's worth, the fact that this likely requires
 non-trivial changes is all the more reason why the GWT team should
 have started on it already.  GWT is billed as being cross-platform,
 and y'all have definitely put in tremendous effort making that true.
 You've created something extremely powerful and developed a very large
 and dedicated community.  With that comes responsibility.

 Your other email that said Dev mode plugins are open source, so if
 someone has interest in keeping them up to date, we're all ears... is
 a bit disingenuous.  Sure, all of GWT is open source, but frankly, the
 community views it as being developed and maintained solely by Google.
  If what you're saying is that Google isn't going to maintain the
 plugins anymore, that's a pretty big deal.  But if you're just
 complaining that the GWT team doesn't have the internal resources to
 keep pace with browser vendors, then my previous suggestion stands...
 hire someone to do that work.

Thanks.

I don't think that's the case per se. The Plugin API still exists
within the WebKit.framework. I saw some rumblings on the 'net about
the API being deprecated, but couldn't find anything definitive on
Apple's developer website.

I'm no Cocoa expert, so there's probably a thousand reasons why I
failed, but I couldn't even get the WebKitPluginStarter example from
developer.apple.com to work. Looks like it was created long ago, so
maybe it's bit-rotted. Safari did load it (unlike the GWT plugin),
but it didn't actually work.

I really wish somebody from the GWT development team would see this
thread (and issue #6601
http://code.google.com/p/google-web-toolkit/issues/detail?id=6601) and
reply.

Lion Safari 5.1 are definitely brand new, but I find it hard to
believe that nobody on the GWT team was involved with the developer
previews of Lion.

GWT-RPC no, RequestFactory yes. GWT-RPC services work only with a GWT
client, but the newer RequestFactory has been designed to support

If you just want a REST interface, however, you might want to look at
resty-gwt on github, which makes it easy to consume REST services from
a GWT client.

I want the GWT app to support live users via the UI and a web API

3rd party library that's worthy?

Re: RequestFactory issue: proxy must include getter if it is to include setter

2011-07-20 Thread David Chandler

Thanks, Ryan. It's a bug.

 I haven't seen this documented anywhere, and I've scrutinized much of
 the documentation, so I don't think I missed it.

 From what I can tell, if you have a proxy that contains a reference to
 another proxy, then you must have a getter in order for the setter to
 work properly.

 If the getter is missing, then the code for the setter will compile
 just fine, but at run-time an IllegalArgumentException is thrown when
 the setter is called, even with an appropriate parameter value.  This
 exception is thrown in AutoBeanCodexImpl.doCoderFor.

 Drilling down into the source code shows that the lack of a getter is
 the problem.

 If this is intended behavior, then it seems to me that it should be
 documented somewhere.  The closest I see is this statement in the
 Getting started with Request Factory document:

 It is not necessary to represent every property and method from the
 server-side entity in the EntityProxy, only getters and setters for
 properties that should be exposed to the client

 This doesn't explicitly say that both getters and setters are required
 for a property.

 The following were two direct quotes from Joseph Smarr (tech lead of google
 plus -- plus.google.com):
 (FYI: The full Q  A with the Google+  Tech Lead can be found
 at: http://anyasq.com/79-im-a-technical-lead-on-the-google+-team)
 we often render our Closure templates server-side so the page renders
 before any JavaScript is loaded, then the JavaScript finds the right DOM
 nodes and hooks up event handlers, etc. to make it responsive (as a result,
 if you're on a slow connection and you click on stuff really fast, you may
 notice a lag before it does anything, but luckily most people don't run into
 this in practice).
 The cool thing about Closure templates is they can be compiled into both
 Java and JavaScript. So we use Java server-side to turn the templates into
 HTML, but we can also do the same in JavaScript client-side for dynamic
 rendering. For instance, if you type in a profile page URL directly, we'll
 render it server-side, but if you go to the stream say and navigate to
 someone's profile page, we do it with AJAX and render it client-side using
 the same exact template. 

 Going from the tone of the above two quotes, it seems to me that the lack of
 server-side templating  system in GWT (GWT has client-side templating in the
 form of UiBinder but not server-side templating) , could have been one of
 the reasons for  not choosing GWT for  the Google+ project.
 What do you guys think??
 Was the lack of server side templating  in GWT one of the reasons why
 Google+ team did not choose GWT ??

 PS: If you guys haven't tried Google+ yet, I would recommend you try it.
 Setting aside how good of a social network/social collaboration tool it is,
 I suggest you guys try it just to get a feel of its UI architecture. Every
 once in a while, an application comes along and raises the bar(eg., Gmail in
 2004) in the area of UI design/UI development and I think Google plus has
 done it this time around.
 Also, I really appreciate the fact that GWT is an exceptional work of
 engineering.  My desire is to just provoke discussion in a direction that
 hopefully leads to making the product even more better and increases its
 technological moat (Warren Buffet

Re: Maven Production Mode

2011-07-18 Thread David Chandler

Hi Kerem,

GWT production mode just means running the compiled JS as you would
any other Web app.

To test production mode, deploy the maven-generated WAR to your
production Web server and start the server. There are Maven plugins
for various servers (Tomcat, jetty) that can automate this, but
discussion of those is beyond the scope of this forum.

You can also start dev mode as usual and just strip
?gwt.codesvr=127.0.0.1:9997 from the end of the URL in the browser.

 A pretty nice way to call server side methods. You are certainly not

Re: Tutorial Create your first web application: application does not work in production mode.

2011-07-13 Thread David Chandler

Hi Scott, your post makes me think it might be time to retire the
webAppCreator Getting Started tutorial in favor of Google Plugin for
Eclipse. It used to be that webAppCreator produced custom shell scripts to
start/stop the app; however, they were a pain to maintain on all platforms
and the Google Plugin for Eclipse offers a better experience overall, so the
only way to start the built-in Web server with the webAppCreator-generated
build.xml is to run ant devmode. The way to switch from dev mode to
production mode is simply to drop ?gwt.codesvr=127.0.0.1:9997 from the
URL. That's the hook that invokes the dev mode plugin in the browser, and
without it, you'll be running the compiled JS instead.

I think it's easier to get started with GWT by working your way down the
left nav in the Google Plugin for Eclipse user guide:
http://code.google.com/eclipse/docs/users_guide.html

Feel free to post back with anything you find confusing.

Re: requestfactory-*.jar libs in GWT 2.4

Hi Alex,

The requestfactory jars in 2.4 are much smaller than gwt-servlet and are

communication. Validation will not be bundled with RF jars. You must
continue to obtain validation from gwt-servlet-deps and/or validation-api +
hibernate-validator jars.

Re: requestfactory-*.jar libs in GWT 2.4

2011-07-13 Thread David Chandler

Minor clarification: a validation impl like hibernate-validator is not
required except for some configurations of Spring, in which case the
presence of validation-api without a corresponding impl will cause server
startup to fail. IIRC, that's why we had to unbundle validation-api from
gwt-servlet.

 Actually, hibernate-validator (or any other JSR303 validator) is not

 (my unit tests are green despite the absence of hibernate-validator FWIW).
 And you can easily turn the warning off if it bothers you, as it's using

 OK, so Spring is worse that I'd imagined ;-)


 IIRC, that's why we had to unbundle validation-api from gwt-servlet.


 Oh, I thought it was because of Maven, and overall dependency management
 (where you'd then have, for instance, to exclude the validation-api
 dependency from hibernate-validator because the lcasses are already in
 gwt-servlet or live with potential conflicts if validation-api is updated to
 1.1 or 2.0 but the 1.0 version bundled in gwt-servlet would be used because
 it comes first in the classpath –i.e. gwt-servlet defeating version conflict
 resolution of Maven, and possibility leading to breakages of third-party
 libs that depend on a newer version).


Yes, it was definitely about Maven. Folks using Maven with Spring were
unlucky enough to spot the problem first.

Re: Anybody has simple way to get Token when implement XRSF protection.

2011-07-12 Thread David Chandler

It depends on what you specify as your token in XsrfTokenServiceServlet (see
the Javadoc). If you use JSESSIONID, then you would need sticky sessions or
session replication as with any use of server sessions.

 On Jul 6, 4:32 pm, David Chandler drfibona...@google.com wrote:
  Hi Joey,
 
  The XSRF token is stateless so you only need to call the XsrfTokenService
  once per server session to obtain it. You can save it as a static
 variable
  in a service helper class. Thereafter, you just need to call setRpcToken
 for
  each service.
 
  Some projects GWT.create() all services in a helper or factory class like
 
  public class ServiceHelper {
 
  private static SomeServiceAsync someService;
 
  static {
  (SomeServiceAsync) someService = GWT.create(SomeService.class);
 
  }
 
  public static getSomeService() {
  return someService;
 
  }
  }
 
  If you do this, you might initialize each service with the token when you
  create it. Thereafter, client code can call
 ServiceHelper.getSomeService()
  in order to make a request. For example, you could put the following in a
  static initializer in the ServiceHelper to obtain the XSRF token when the
  app loads:
 
  XsrfTokenServiceAsync xsrf =
  (XsrfTokenServiceAsync)GWT.create(XsrfTokenService.class);
  ((ServiceDefTarget)xsrf).setServiceEntryPoint(GWT.getModuleBaseURL() +
  xsrf);
  xsrf.getNewXsrfToken(new AsyncCallbackXsrfToken() {
 
   public void onSuccess(XsrfToken token) {
 initSomeService(token);
 initNextService(token);
 ...
 });
   }
 
  As far as handling the XSRF exception centrally, you can wrap
 AsyncCallback
  with your own class like XsrfProtectedCallback in which you implement
  onFailure(). This is a good practice anyway in order to provide uniform
  error handling for your RPC calls. See HupaCallback in the Apache
 HupaMail
  project for an example of a wrapped callback.

Re: Ways to reduce GWT compiled code size

2011-07-11 Thread David Chandler

Have you seen
http://www.google.com/events/io/2011/sessions/high-performance-gwt-best-practices-for-writing-smaller-faster-apps.html?
Also check out the performance-related sessions from previous years at I/O.

Your observations appear sound: if you add a widget with lots of
dependencies, you're going to see a significant bump in code size. It has
often been noted that RequestFactory is bigger than RPC in terms of initial
download; however, if you include a Command pattern implementation and the
extra classes required to use Command pattern with GWT RPC, I doubt it's
much different. And RequestFactory should give you smaller payloads than GWT
RPC because it sends only deltas and doesn't send the whole object graph by
default.

It sounds like you're taking the right approach. Try out different widgets /
features for your application and measure the resulting size (hopefully
you're using -compileReport to get additional size-related info?) Because
the GWT compiler does whole program optimization, this is the only way to
get results that are accurate for your app.

On Sun, Jul 10, 2011 at 1:20 AM, Andrei vol...@spiraluniverseinc.comwrote:

Concerns about the size of GWT complied code has been raised several
times in this forum, but a typical response was Relax, dude! with
slight variations like It can be cached and Don't forget about
gzip. I am still concerned, though, that even the most simple GWT
app easily tops 150kB in compile size.

I started looking at the compile reports, and I noticed some
interesting things.

(1) I imported java.util.Comparator in one place in the app, and it
immediately added a ton of Java classes to the compiled code,
including Java.util.Date, java.lang.Float, java.lang.Double, and so
on. I don't use this classes anywhere in the app, and the compile
report traces them all to java.util.Comparator. I did not measure
precisely, but I've got around a 10kB bump in the compiled app size
after using comparator once (and I use it to compare String properties
of two objects).

(2) I don't use dates or time anywhere on the client side. I have one
server-side method which uses dates by adding a timestamp to an
Appengine Datastore. So I was very surprised to see
java.sql.Timestamp, java.sql.Date, and java.sql.Time, in my compile
report. These classes are not big, but why they were included? I don't
send date or time over the wire (and I don't use sql), but I see them
traced to

com.google.gwt.user.client.rpc.core.java.sql.Time_CustomFieldSerializer::instantiate.

(3) In my app many classes are traced exclusively to DockLayoutPanel,
including java.util.AbstractHashMap, java.util.HashSet, and the like.
Is there an assessment anywhere of how heavy each widget is in terms
of its impact on the compile size? It's very hard to figure out as
each widget has a different impact based on which other widgets are
already present, and some widgets have no real alternative anyway
(CellTable is very heavy, for example, but I have to use it
regardless), but any tips/guidance would be appreciated.

(4) I never used anything touch-related in the app, but
com.google.gwt.touch.client is present in the compile report. All of
its subclasses trace back to ScrollPanel. I guess it may be useful in
some use cases, but I would like to have a way to turn it off when I
offer a separate GWT file for mobile devices.

(5) I replaced RPC calls with RequestFactory, and the compile size
ballooned by 150kB (the app had only two RPC calls at that stage). The
benefits of RequestFactory quickly paled in my eyes. Did I do
something wrong, or other people had similar results?

I understand that as the app gets bigger and bigger (and the Internet
faster), these issues will be comparatively less and less important. I
do have, however, customers with slower connections / in remote
locations / on expensive mobile data plans, for whom initial download
size matters. Not to mention extra bandwidth costs which grow in line
with the number of customers (Isn't that the reason Gmail, YouTube,
and Google+ are not written in GWT?). I would be grateful if the
experts on this forum share their tips on reducing the compile size of
the app.

Re: GWT Developer Job Openings

2011-07-11 Thread David Chandler

As a moderator of this group, I reject almost a dozen job postings per day.
Several per week actually relate to GWT, but even so are inconsistent with
this forum's mission. However, I approved Jeff Burnham's post because I
think there is some benefit in this discussion.

The GWT team doesn't feel that it's our place to maintain a GWT jobs forum;
however, if the community wants to take this on, we'll certainly be glad to
help promote it. Also, if there are things you want recruiters to know, I'll
be happy to write up a sticky post with info for recruiters (as well as a
restatement of the job postings ban on this forum).

In the mean time, if you're a GWT consultant looking for work, here's some
advice I can offer as a former consultant.

1. The best jobs are those that find you, so make yourself findable. Write a
GWT blog. Put GWT developer in your Google+ and LinkedIn profiles with a
link to your Google Groups profile so recruiters can see how often you post
on this group. Also put GWT consulting or something more descriptive in
your signature so it shows up in every post on this group. Good recruiters
know how to search Google Groups and StackOverflow to find the real experts.

2. Give a GWT talk at your local JUG or GTUG. Recruiters often frequent the
larger JUGs and if you're giving the talk, you're their expert.

3. Get your resume in the database of every credible technical staffing shop
you can find. Apply for every GWT job. Even if it's slightly over/under your
abilities, that will get you in the recruiter's resume database. Put a link
to your online profiles in your resume so they can read your blog, see how
long you've been posting on this group, etc.

4. Post your resume in the various online job services like Dice and
Monster. Don't just search for jobs--make yourself searchable. Many jobs are
never posted--the recruiters search the online databases and contact you
directly. Also make sure you update your resume in these services every
couple months as recruiters tend to look for recent updates.

Again, let me know where you want me to direct GWT job postings, and I'll be
happy to help out.

Re: Request Factory More Secure ?

2011-07-11 Thread David Chandler

Hi Vincent,

RequestFactory is not inherently any more or less secure that GWT RPC. With
either approach, you should protect RPC calls for sensitive data with SSL
and protect against XSRF attacks by sending a token with each request
payload. For more info, see

http://code.google.com/webtoolkit/doc/latest/DevGuideSecurity.html
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/f0f74b0734f04a1c

As for the second part of your question, you are correct. On the client
side, RequestFactory works with proxy (interface) representations of
entities. RequestFactory automatically converts between the proxy
representation and the server-side entity when sending / receiving.

2011-07-07 Thread David Chandler

Certainly you can deploy an HTML+JSP Web site in Google App Engine.

You don't mention what you're comparing it to, but App Engine Web servers
are located in data centers all over the world and there is built-in edge
caching of static resources (HTML, CSS, images), so it's quite fast from
most locations.

The free quotas are generous--give it a try.

 Certainly you can deploy an HTML+JSP Web site in Google App Engine.

 You don't mention what you're comparing it to, but App Engine Web servers
 are located in data centers all over the world and there is built-in edge
 caching of static resources (HTML, CSS, images), so it's quite fast from
 most locations.

 The free quotas are generous--give it a try.

Re: Anybody has simple way to get Token when implement XRSF protection.

2011-07-06 Thread David Chandler

Hi Joey,

The XSRF token is stateless so you only need to call the XsrfTokenService
once per server session to obtain it. You can save it as a static variable
in a service helper class. Thereafter, you just need to call setRpcToken for
each service.

Some projects GWT.create() all services in a helper or factory class like

public class ServiceHelper {

private static SomeServiceAsync someService;

static {
(SomeServiceAsync) someService = GWT.create(SomeService.class);
}

public static getSomeService() {
return someService;
}
}

If you do this, you might initialize each service with the token when you
create it. Thereafter, client code can call ServiceHelper.getSomeService()
in order to make a request. For example, you could put the following in a
static initializer in the ServiceHelper to obtain the XSRF token when the
app loads:

XsrfTokenServiceAsync xsrf =
(XsrfTokenServiceAsync)GWT.create(XsrfTokenService.class);
((ServiceDefTarget)xsrf).setServiceEntryPoint(GWT.getModuleBaseURL() +
xsrf);
xsrf.getNewXsrfToken(new AsyncCallbackXsrfToken() {

 public void onSuccess(XsrfToken token) {
   initSomeService(token);
   initNextService(token);
   ...
   });
 }

As far as handling the XSRF exception centrally, you can wrap AsyncCallback
with your own class like XsrfProtectedCallback in which you implement
onFailure(). This is a good practice anyway in order to provide uniform
error handling for your RPC calls. See HupaCallback in the Apache HupaMail
project for an example of a wrapped callback.

HTH,

Re: Google Products using GWT

2011-07-06 Thread David Chandler

Fundamentally, it's because engineering teams at Google are free to choose
their own tools. The Architecture Police don't work here. There are many
instances where Google tools or products compete with each other like GWT
and Closure. In Google culture, that's generally viewed as healthy as it
allows freedom of choice and provides incentive for competing frameworks to
continually improve.

As for Google+, I don't know any specifics, but lots of factors typically
come into play as with any company: the team's skillset and preferences,
whether the app is in framework X's sweet spot, etc. I don't understand it
personally, but some people really like JS, and Google has a lot of (very
good) JS developers.

Re: Should gwt-dev.jar be on classpath on webmode?

Make sure you have only one GWT version on your classpath. The gwt/dev/asm
classes are in gwt-servlet.jar, which should be the only GWT jar you need on
the server side (along with validation-api.jar and json.jar).

Also, in order to get the benefits of Guice injection for RF services,
you'll need a little more sophistication. See

Re: GWT RPC Service Proxy/Wrapper

2011-07-01 Thread David Chandler

Hi Andreas,

This is exactly why using the Command pattern a la gwt-dispatch is
recommended :-) You can use a servlet filter for basic centralized handling
such as authentication or have all your service impls extend a base class
that extends RemoteServiceServlet, but those are the only ways I know of to
get the low-hanging fruit.

 Hi all.

 I'm currently working on a project that has both client side and
 server side components. The server side code and the RPC services have
 already been defined and implemented by one party and my team is now
 about to develop the client side GWT app.

 I have previously worked on projects where we used gwt-presenter and
 gwt-dispatch using a Command pattern style for RPC. However, in this
 project the services have been implemented more as an API with named
 methods that each maps to underlying DAOs.

 We are now looking at how to implement client side caching and other
 centralized request/response handling around the RPC services. The
 problem we're having is that there are a large number of service
 methods defined, as opposed to one execute() method that you typically
 find when using dispatch/Command pattern. Hence, it is not straight
 forward as to how we would hook into these services and implement
 caching and other generic handlers without re-writing the services and
 it's server side implementation.

 We have something like 3 services each looking like this.
 Service
 methodA(...)
 methodB(...)
 methodC(...)
 ...

 What is the best or preferred way to wrap or hook into these calls to
 provide caching and any other generic handling we may want to provide?
 It doesn't seem very efficient to wrap the services and hook into each
 separate method. We are looking to solve this client side rather than
 re-writing the server-side implementation.
 Note that the server-side component was implemented without our
 involvement.

 Thanks in advance.

 Andreas

Re: Google Products using GWT

2011-07-01 Thread David Chandler

Hi Kevin,

There are several hundred projects within Google using GWT and more are
being written or rewritten all the time. Some of the major ones:

AdWords UI
AdSense UI
Blogger (
http://techcrunch.com/2011/03/14/half-a-billion-blog-posts-later-google-to-give-blogger-a-revamp/
)
Groups (new UI)
Doclist (the folders in docs, both desktop and mobile versions)
Parts of Maps / Geo

For a broader view of companies using GWT, have a look at the companies
featured in this year's Developer Tool Sandbox at I/O (
http://www.google.com/events/io/2011/sandbox.html#developer-tools) as well
as the case studies posted on the GWT doc site (
http://code.google.com/webtoolkit/casestudies/index.html). Also note that
this forum continues to add members at the rate of ~500 / mo. GWT is still
growing.

Also watch trunk on SVN. Googlers continue to improve GWT every day, and
lots of the new features in the last year have been driven by Google
projects (notably UIBinder, Activities and Places, and cell widgets).

The real question is whether GWT is a good fit for your project. We
generally find that teams with strong Java experience writing rich,
desktop-like apps benefit the most from GWT. Lots of people on this forum
will tell you that if you start with pure JS and your code base grows,
you'll soon reach a point where you wish you'd written in GWT. Don't kid
yourself--there is a learning curve, especially for server-side developers
not used to writing asynchronous, event-driven clients, but if your project
is a good fit, you won't look back.

I realize that this question was asked in this thread, but seeing as the
response was a few years old I thought I would pose the question again.

At work there has been a ton of discussion (putting it nicely) about the
use of GWT inside the organization. It doesn't seem to be enough to those
opposing the use of GWT to point out the several production applications
running to the not so many pure javascript applications running. With the
recent release of Google+ the topic has arisen again with those in the
opposite camp pointing out that Google+ source appears to not be using any
GWT. They are using this to argue that not even Google is using GWT to build
their suite of products.

So, sorry for posing another question about this, but I would be curious
about an updated list of Google products that use GWT. Thanks.

Re: Very confusing aspect of MVP documentation!

2011-07-01 Thread David Chandler

While it's true that gwt-platform is not supported or endorsed by Google,
note that gwt-platform creator Philippe Beaudoin was invited to present at
Google I/O this year (see the video at
http://code.google.com/p/gwt-platform/). Also note that both gwt-platform
and Activities and Places are built on the same core History support in GWT,
which did not change with the 2.1 release and is unlikely to change. While
GWT may continue to add new features in Activities and Places, I don't
anticipate any changes that would break gwt-platform. The GWT team values
the many 3rd party projects around GWT and generally tries to keep core GWT
APIs as loosely coupled as possible in order to permit different development
styles.

 I would imagine that GWT-Platform is better than GWT's native MVP (by

 sufficient but it has worked well for us. It's not unreasonable to
 assume that Google will enhance it in the future. What happens then
 for development shops that have migrated to GWT-Platform and they are
 tempted to switch back? They have existing code that uses another

 Messy right?

   Personally, I think that the reference to these articles should be

  What is the best MVP we can use with GWT? I am currently looking for
  some lightweight MVP framework with some samples that will give me the

Re: How do you guys solve this problem?

Magno is correct. You can create multiple proxy representations of an
entity, so could have ClientProxy with accessor methods for all properties
and LightweightClientProxy with only getId() and getStringRepresentation().

 With Sale being:

 }

 John Doe(2) is the name of the client and 2 is the id. Same thing for
 Product.
 The problem is that to find out the Client's name I need to send it to the
 client (in the case of RequestFactory as a ClientProxy).
 I don't want to send the whole Client throw the wire when I only need the
 id and a string representation. Plus, the example being a table, it may be
 listing 30+ Sales, and include the relationship makes it really heavy to
 load.

 The question is how can I do with RF to get a string representation and
 the id of a Proxy without loading it all?

 Before using RF I used two object i.e: Sale and SaleDto, and I made the
 conversion myself on the server.

Good point, Thomas. Agreed, the POMs should be part of the open source
project, and community participation is welcome. I'll work on getting them
checked in.

As for the group/artifact IDs, I expect we'll want to use groupId
com.google.web.bindery with artifacts requestfactory-server and
requestfactory-client. I'll double-check to make sure there are no GWT
references in the jars, but I'm sure that was the intent of moving to
com.google.web.bindery. Does this make sense?

Hi Aidan,

I also see the AutoBeanFrozen error with persistAndReturn in GWT 2.3.0 and

And yes, Request.fire() just calls RequestContext.fire(), so the effect is

ObjectifyDao dao = new ObjectifyDao();
this.aBool = true;
KeyParent key = dao.ofy().put(this);
return dao.ofy().get(key);
}

 In my App's RequestFactory interface, I have this:

   @Service(Parent.class)
interface ParentRequestContext extends RequestContext {
InstanceRequestParentProxy, Void persist();
InstanceRequestParentProxy, ParentProxy
 persistAndReturn();
}
ParentRequestContext getParentRC();


 Then when I want to create and persist a new Parent object, I do this...

  ParentRequestContext rc = rf.getParentRC();
  ParentProxy proxyObj = rc.create(ParentProxy.class);
 (.. set some properties..  )

 RequestParentProxy fetchRequest = rc.persistAndReturn().using(proxyObj);
 fetchRequest.to(new ReceiverParentProxy(){
   (... onSuccess Handler.. )
 });

 fetchRequest.fire();

 However I get the 'autobean has been frozen' error (stack trace:
 http://pastebin.com/NZ7280B9 )
 Its clear from the stacktrace and other debug messages that the object
 is persisted, but returning it fails.

 So...

 Is this possible?  Is it desirable?

 Also, if we look at the last line, fetchRequest.fire(), we could also
 do rc.fire()  instead of it, and get the same result.. Are we doing
 the exact same operation when we call either 'fire' method?

 Thanks,
 Aidan.

Re: RequestFactory - persist method that returns the saved Entity.

2011-06-29 Thread David Chandler

Aidan, thanks so much for sharing your success!

   This was failing:


KeyNamedList key = this.put(list);

return this.get(key);


but this works:

KeyNamedList key = this.put(list);
return list;

I'll have to look closer at what changed between 2.2 and 2.3 that might be
causing this.

Re: .setVisible(true); // I can't see what I am missing

2011-06-27 Thread David Chandler

The implementation of RootPanel.setVisible() uses the style attribute
display, which is orthogonal to visibility:hidden.

 public static native void setVisible(Element elem, boolean visible)
/*-{

elem.style.display = visible ? '' : 'none';

  }-*/;

Best form is to control visibility using styles directly OR by calling
setVisible(), but don't mix the two.

Re: GWT integration to the cloud

2011-06-24 Thread David Chandler

We've seen very little interest in GWT-Roo integration on this forum. It
seems that most folks want to use GWT RequestFactory and Activities  Places
without code generation, so we've chosen to prioritize effort around making
that easier (for example, ServiceLocators and issues 5807, 6234 make it
possible to inherit generic service methods vs. generate them).

Technically, GWT-Roo integration is structured as a Roo add-on so Spring
needs to be at least involved in any further work.

Are you just wanting to kick the tires or have you already adopted Roo and
have a really strong use case for GWT integration also?

 Also what is the reccomended way for integration of GWT with the cloud

The proxy you get from RequestContext.create() won't be updated

 saving it, because a database trigger populates some tables associated
 with the object when it is first created.  On the server side, I see
 those fields being assigned values in my debugger after the refresh.
 I do update the version number field for the object on the server in
 my service method.

 However, on the client side, the proxy returned by
 RequestContext.create does not have those new values; the collection
 containing them is still null, as it was before I persisted the
 object.

 I have some ideas on how to fix this, but I'd love to hear suggestions
 on the best way to do it.  I feel like the client-side event bus stuff
 could be involved here, but honestly I don't know much about how that
 works - where is a good place to look for docs (the getting started
 with RequestFactory guide doesn't really talk about it).

  Ryan, you're correct. Nothing on the server gets called until you fire()
 the
  request, so your default properties won't be immediately available on the

   I think you're referring to the client-side create method; my question
   about create is mostly what the server-side version is used for.
 
   The context of the question is this:  I have a Boolean property for my
   domain object.  If I RequestContext.create a proxy and then try to
   access the Boolean, I get null.  My domain object sets this property
   to a default value in its constructor, but the constructor is not
   called if all I do on the client is RequestContext.create the proxy.
   I was hoping to be able to write default values for properties in a
   single place.  The domain object on the server seems to be the most
   logical place.  Currently it seems that I need to save the new proxy
   on the server after RequestContext.create'ing the proxy for this to
   happen.

Also search these archives for eventbus example. There are several. Apache
HupaMail source makes nice use of the EventBus, IIRC.

Re: extending requestContext fo common functionality?

2011-06-23 Thread David Chandler

Server-side inheritance of RequestFactory services with generics works
fine. See
http://turbomanage.wordpress.com/2011/03/25/using-gwt-requestfactory-with-objectify/

Client-side inheritance of RequestContext interfaces is coming in 2.4. See
http://code.google.com/p/google-web-toolkit/issues/detail?id=6234

Happy generifying!

 i know this has been asked before, but i'm not sure how to respond to
 it.

 given that requestContext and it's implementation parallal the Dao's
 of jpa, it's plausible to create a generic dao with entity methods
 like persist

 so i thought i would create a generic interface like
 CommonRequestContext that would extent the RequestContext and define
 persit method with the same signature of edit ... create etc. (using
 base proxy)

 i also thought about creating a common base class of the actuall dao
 that would define persist in a generic way.

 none of the options and alternatives i tried, worked because the gwt
 compile doesn't treat generics the same way as java..

 anyone tried something similar?
