No source code is available for type javax.xml.parsers.DocumentBuilderFactory

2011-09-01 Thread Vrushali Patil

Hi,

I am new to Java and GWT. I am trying to parse a xml, which I have
written as stringbuilder.

1) I tried using XMLParser.parse(xmlstring); but it gave a
DOMException tat string is crossing max length. Is there any way to
work around this.

2) I used DocumentBuilderFactory ... the code is as follows. It gives
the error as

No source code is available for type
javax.xml.parsers.DocumentBuilderFactory - It is some sort of
Inheritance issue. But I am unaware of what exactly inherit name i
should be using. Please guide.

Seperating the hosting of the client and server

2011-09-01 Thread Sander Smith

I'm trying to seperate the client side of my GWT app (the JS files)
from the server side by hosting them in different places. So the
static JS is at www.host1.com and the Java web app stuff is at www.host2.com.
To communicate, I simply pass the fully qualified URL (http://
www.host2.com/...) into setServiceEntryPoint().

Things aren't working, and I don't know why. I've looked through the
documentation to see if this is allowed, and can't find anything that
says it's not. I have a gut feeling that this is violating some sort
of JS security issue, so I wanted to check before continuing.

Am I able to do what I want?

Re: Extra Outer ScrollPanel in Firefox

2011-09-01 Thread leslie

A beautiful thing happens.  The extra scroll bars go away and the
ListBox contains it's own vertical scroll bar which functions in the
expected and desired way.
Great stuff.  Michael I thank you very much.  This is a big help to

 What happens if you drop the scroll panel, and just add the list box?

  I'm having difficulty with my application rendering in Firefox.  I've

  ScrollPanel.

  ListBox list = new ListBox();
  ScrollPanel scrollpanel = new ScrollPanel( list );
  VerticalPanel main = new VerticalPanel();
  main.add( scrollpanel );

  When the component appears in the Firefox browser, horizontal and the
  vertical scrollbars appear on some sort of outer component, as an
  extra ScrollPanel even before the list is populated with names.
  Moreover, when the listbox becomes populated, I see the proper
  Vertical scrollbar for the list box but the outer scrollbar remains.
  That is, I can see a properly configured ListBox within a ScrollPanel,
  within some form of unknown ScrollPanel.

   By contrast, In Safari I observe the desired behavior.  That is, the
  scroll bars do not appear until the list is populated with names.  At
  that time, the vertical bar appears and it functions in the desired
  way, scrolling the list so that the names become visible.  There are
  no other scroll bars other than what are expected.

  I've come across a thread somewhere that suggested I must resize the
  ListBox because it is too wide.  But too wide for what?  What is
  causing the extra ScrollPanel to appear in Firefox and how can I
  remove it?  Many thanks.

For anything going over the wire via RPC, yes.

For anything that stays within the client, it doesn't matter.

If your HTML host page is on host1, then you won't be able to use GWT-RPC, 
RequestFactory or RequestBuilder to communicate with host2 (well, that's not 
entirely true, but if IE is to be supported, then consider it's simply not 
possible).

You can however deploy your HTML host page on host2 and your JS at host1. 
You'll have to use the xsiframe linker for your code to be loaded in the 
web page though, but it's as easy as adding a line to your gwt.xml:
add-linker name=xsiframe /

How to mock Listbox when testing the Presenter class?

Presenter:
public interface Display  {
HasText ageTxtBox();
HasClickHandlers incrementButton();
}

View implements Presenter.Display interface:
@UiField Button incrementButton;
@UiField TextBox ageTxtBox;

@Override
public HasText ageTxtBox() {
  return ageTxtBox;
}

@Override
public HasClickHandlers incrementButton() {
  return incrementButton;
}

How do we do this for a Listbox in a view?

@UiField ListBox listBoxAdmin;

The methods on listBox I am using are:
addItem
getItemCount
getSelectedIndex
getItemText
getValue
removeItem
clear


How can I test my listbox functionality which is in Presenter with a
mock Listbox? What interface it need to implement?

[ANN] Scala+GWT 0.1-M1 released

2011-09-01 Thread Grzegorz Kossakowski

Hello,

I'm excited to announce first milestone of Scala+GWT project.

Download (and then follow README instructions) from here:
http://goo.gl/Ym3xU

Release notes (included below) can be found here: http://goo.gl/H8san

Scala+GWT 0.1-M1

The first official milestone release from the Scala+GWT project.

This release consists of just samples packaged along with snapshot
of jars needed to build them. Those jars include our own version
of both GWT and Scala.

This release doesn't come with any official artifacts apart from the
tarball you can download from http://github.com/scalagwt/scalagwt-sample.

### What works

Samples show it the best. Here are some highlights:

* Mixed Scala/Java projects work very well (for GWT-supported Java subset)
* Most of Scala language constructs are supported
* Most of Scala library code that makes sense in a browser context is
supported, including Scala collections

It's fair to say that we are not sure how far one can go with this release.
It might be that you can already
build something useful with what we already have. The only way to be sure is
start hacking!

### Known issues

* Compilation is very, very slow.
* `scala.immutable.{TreeMap, TreeSet}` are not supported due to various
bugs (thus sorted collections don't work)
* many patterns in pattern matching logic are not supported (tough issue)
examples include
* pattern alternatives (`|`)
* guard patterns (`if` guard)
* GWT's development mode is broken
* We are compiling with all optimizations turned off. This results in a
slow and very large JavaScript code.

### Reporting issues

We appreciate feedback. If you find something that doesn't work (e.g.
crashes either Scala or GWT compiler)
or JavaScript gives you weird results we'd love to hear about it. The most
effective way of reporting issues
is to modify `Hello World` sample to show your problem. Exact steps are:

1. Fork `scalagwt-sample` repo from here:
http://github.com/scalagwt/scalagwt-sample
2. Clone it: `git clone git://
github.com/YOUR_USER_NAME/scalagwt-sample.git`http://github.com/YOUR_USER_NAME/scalagwt-sample.git
3. Modify hello world sample located in
`src/com/google/gwt/sample/jribble/client`
4. Commit and publish your example.
5. File a ticket here: http://github.com/scalagwt/scalagwt-sample and
mention your
fork while explaining your issue.

If you want to discuss your problem before reporting it, join
[scala...@googlegroups.com](http://groups.google.com/group/scalagwt).

### What if I don't know GWT?

That shouldn't be a big problem. You've got Scala source code for samples
that show basic functionality
and provides basic setup. You may want to start with channging hello world
sample, recompiling it and
testing in a browser.

### What if I don't know Scala?

You might still want to check out samples to see how they might look like in
other language than Java.
We'll be cutting a lot more of boilerplate code once GWT libraries and APIs
receive enough of Scala's
[pimp-love](http://www.artima.com/weblogs/viewpost.jsp?thread=179766).

### Need help? Want to discuss something?

Join us here: [scala...@googlegroups.com](

Happy playing!

Re: Requestfactory : best practice for persisting updates with Locator

2011-09-01 Thread Dominik Steiner

Perhaps a small test case might better explain what problem i'm facing
with the delta's send from request factory to the locator class (the
fire() method is in order to do synchronous testing of the requests
sent)

@Test
public void testPersistAndUpdate() throws Exception {
SomeRequestContext addRequest = requestFactory.someRequest();
FooProxy fooProxyCreated = addRequest.create(FooProxy.class);
fooProxyCreated.setName(fooname);
BarProxy barProxy = addRequest.create(BarProxy.class);
barProxy.setName(barname);
fooProxyCreated.setBars(Arrays.asList(barProxy));

IntegerResponseProxy addResponse =
fire(addRequest.persist(fooProxyCreated));
assertEquals(null, addResponse.getErrormessage());
assertNotNull(addResponse.getValue());
Integer id = addResponse.getValue();

SomeRequestContext findRequest = requestFactory.someRequest();
FooProxy fooProxyFound = fire(findRequest.find(id).with(bars));

SomeRequestContext updateRequest = requestFactory.someRequest();
fooProxyFound = updateRequest.edit(fooProxyFound);
BarProxy bar = fooProxyFound.getBars().get(0);
bar.setName(newname);
IntegerResponseProxy updateResponse =
fire(updateRequest.persist(fooProxyFound));
assertEquals(null, updateResponse.getErrormessage());
assertEquals(id, updateResponse.getValue());
}


So on the server the service method just looks like this

public IntegerResponse persist(Foo foo)

and the
public class Foo{
   Integer id;
   String name;
   ListBar bars;
|

and Bar might have a composite id

public class Bar {
BarPK barPK;
}

public class BarPK{
   Integer fooId;
   String name;
}

When it is created all properties gets sent to the persist() method
and the full object can easily be persisted using hibernate. The
second time an update is occuring on that object the fooId will be
null as no changes have been made to that on the client evidently.
This makes working with the Foo foo object in the persist method quite
manual. And how would i differentiate if some null property is just
not sent because no update has occured or because it has been reset to
null? Is such a use case not supported by RF and i have to stick with
RPC?

Thanks for any hints

Dominik

Re: How to mock Listbox when testing the Presenter class?

I'd highly encourage you to use the pattern from the MVP - part 2 article 
from the GWT doc, where the presenter itself implements an interface that 
the view calls back, rather than exposing the view through HasXxxHandlers 
and the like. It makes mocking so much painful! (having to mock 
HasXxxHandlers is a PITA compared to simply mocking your View interface, and 
capturing the presenter from the setPresenter method so you can call methods 
on it as if the view did it).

To answer your question, your view should expose the methods you use from 
the ListBox (and simply delegate them to the listbox); you shouldn't try to 
expose the listbox as an object from your view (because as you said, 
there's no matching interface). So you'll add those 7 methods to your view 
(possibly using a naming scheme such as getAdmin, setAdmin, etc.).
Also, instead of a ListBox, you could use a ValueListBox so you can directly 
push your model to your view, and get the selected object back from the 
view.

Aw: No source code is available for type javax.xml.parsers.DocumentBuilderFactory

2011-09-01 Thread Jens

In general you can only use Java classes on the client side (everything that 
is in your client and shared package) listed 
in: http://code.google.com/intl/de-DE/webtoolkit/doc/latest/RefJreEmulation.html

So you can not use most of the classes in your code on client side. 

You have to:
- use XMLParser 
(http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/gwt/xml/client/XMLParser.html)
- write your own client side string parser that converts the xml string to 
something you want to have 
- parse the XML on server side and ask the server for the information you 
need

I haven't used XMLParser yet but it seems to me that the xml string you want 
to parse isn't that long so I think it should work.

Re: How to mock Listbox when testing the Presenter class?

My ListBox is inside a custom composite widget I have created. I am
using this widget in my different views in my application.

Just to elaborate more on this widget which I created, it is a Dialog
Box which has Left ListBox and Right ListBox. There are 4 buttons on
the center which allows to move items from Left to Right or Right to
Left. They can be moved one at a time or all at once. So when I
created this ListBox using GWT Designer as a New-Windows Builder-
UIBinder - DialogBox I don't get any presenter or activity with that.
Plus I don't want an activity simply because I don't want a new place.
I am opening this custom dialog box within my same place and I don't
want to write the processing code of moving items from either side
inside my current activity because then If my two different views want
to use this custom dialog box I have to duplicate the code. The whole
idea of this Widget was to have self-contained code.
The problem I see with GWT designer is all the event handling code
goes inside UIHandler method which is still inside my
CustomWidget.java file.

How do I then test my widget not inside GWTTestcase?

I introduced a presenter to use classic MVP approach and move my
processing logic inside presenter that way I can test my presenter my
mocking GWT widgets as my own custom widgets.

MVP-Part 2 deals with Activities and Places which works fine when you
are using GWT widgets inside a View. But when you have a re-usable
widget you created I don't want to assign new place and activity for
every custom widget I create. Because I really want to test my widget
and not the view here. See the difference here?

 To answer your question, your view should expose the methods you use from
 the ListBox (and simply delegate them to the listbox); you shouldn't try to
 expose the listbox as an object from your view (because as you said,
 there's no matching interface). So you'll add those 7 methods to your view
 (possibly using a naming scheme such as getAdmin, setAdmin, etc.).
 Also, instead of a ListBox, you could use a ValueListBox so you can directly
 push your model to your view, and get the selected object back from the
 view.

Hi I tried using XMLParser as u suggested. But getting this error.

length());


xmldoc = XMLParser.parse(xmlstring); *\\ Error at this line*

 In general you can only use Java classes on the client side (everything

 So you can not use most of the classes in your code on client side.

 You have to:
 - use XMLParser (
 http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/gwt/xml/client/XMLParser.html
 )
 - write your own client side string parser that converts the xml string to
 something you want to have
 - parse the XML on server side and ask the server for the information you
 need

 I haven't used XMLParser yet but it seems to me that the xml string you
 want to parse isn't that long so I think it should work.

Re: How to mock Listbox when testing the Presenter class?

I think I got it what you saying. I got caught up with MVP-Part 2 in
terms of activities and places and kind of lost the major
understanding of what it is ultimately trying to tell you to avoid
HasXxxHandlers.

So I have one question here.. If my presenter implements the interface
which view calls back and how does presenter will get hold of my
listbox defined in the view?

Re: How to mock Listbox when testing the Presenter class?

It won't; it only talks to the view through the Display interface (or 
possibly if it's really complex, through sub-objects, but try as hard as 
possible to keep them seen as interfaces or mockable objects –i.e. objects 
that you can extend to remove all JSNI dependency– or you'll need a, 
sluggish, GWTTestCase).

(to quickly answer your previous message, which I didn't read 'til the end, 
it doesn't really matter how your view is implemented, what matters is how 
your presenter talks to it, the granularity of the protocol/contract 
impacting how much code you can unit-test without a GWTTestCase: the more 
code in the presenter, the more code can be tested without GWTTestCase, but 
also the more complex the presenter, which makes it less readable and 
maintainable)

mailto: links in Google Chrome

2011-09-01 Thread melody

I am trying to implement mailto: links in my application. When I use
the mailto: link with the target attribute as shown below, the browser
opens the email program fine but closes my GWT program by moving the
browser to about:blank page.

a href='mailto:myem...@mail.com'Send Email/a

The same link works fine in Firefox without closing my GWT application/
page.


If I use the following link with the TARGET attribute, the email
program is opened correctly but Google Chrome annoyingly opens a new
tab with the URL about:blank

a href='mailto:myem...@mail.com' target='_blank'Send Email/a

Again the same links work fine in Firefox.

Is there a way around this Google Chrome problem with email links?

Re: Is it still preferable to have HashMapString, Panel over MapString, Panel in GWT client side code?

2011-09-01 Thread Colin Alworth

In general the compiler will select the most specific type it can - if you 
write
MapString, Panel map = new HashMapString, Panel();
it will change that to
HashMapString, Panel map = new HashMapString, Panel();
as it is clear that the object can only be a HashMap at that location. In 
other cases it may not be able to make that promotion, but there is no 
'extra code' to convert from one to the other, as HashMap implements Map, 
and Map's methods may then be invoked on HashMap.

The one slight cost that could exist would be when the compiler attempts to 
turn instance methods into static methods, as to avoid the small cost for 
dynamic dispatch. It is worth noting that making this change throughout your 
codebase is unlikely to cause a significant size difference, as Widget has a 
HandlerManager, and HandlerManager has an EventBus, usually of type 
SimpleEventBus, which has a Map in it, where the actual value is a HashMap. 
Thus both classes are necessary (assuming you use any Widget or Widget 
subclass in your app), as is the ability to refer to a HashMap as a Map.

This is the key to your issue - if the client can't de-serialize it (because 
the code only exists where the server can see it, not the client), it can't 
allow it to be thrown to the client. 

Unless I've misunderstood, and all three are declared in the client package, 
but only AException is declared as part of the RPC method signature. If that 
is the case, this should work as you expect. A few other things could B, C 
from being available to be deserialized, such as being blacklisted in your 
module file, or not having default (i.e. no-arg) constructors, things that 
would affect any other DTO expected to work with RPC.

Locking bottom panel of SplitLayoutPanel to bottom of viewing area

2011-09-01 Thread Rike255

The basic design of the page I'm building is a SplitLayoutPanel with a
north and center panel.  The north panel has the body of the page
(TabLayoutPanel and ScrollPanel) and the center panel holds a
HorizontalPanel with textbox+buttons.

What I'm trying to do is have the page load with the center panel
taking up a certain part of the window (say 40px) every time and if I
resize the browser window the center panel stays the same height so
the north panel either grows or shrinks with the window.  The center
panel will always take up only the bottom 40px of the browser window.

I'm not very strong in css so this is proving way over my head haha.
Any thoughts?

Thanks!

Re: mailto: links in Google Chrome

2011-09-01 Thread karim duran

Hi Melody,

In my opinion you shouldn't use target attribute with an email link. Target
attribute tells the browser how it should manage the link (e.g in the same
window, in the parent window, in a new window). It's appropriate for Web
browsing, not for email.

When the browser meet a email link mailto, it just asks the system to open
your client mail software as you said.

I agree with you, it's strange that you are redirect to about:blank page. I
can't reproduce this incident in a simple exemple. But my Google Chrome
version is old.

Does this pb happen in dev/test mode ? Or in deploiement mode ?
May be you can try to use a GWT link instead of hard coded HTML mailto link.

I hope it helps.

Editor and RequestFactory

2011-09-01 Thread Brian Chapman

I have a question about using the RequestFactoryEditorDriver. I am trying to 
use the editor with request factory on the client side. On the server side I 
am using Objectify which is modeled after the 
listWidgethttp://code.google.com/p/listwidget/example. I have a 
ProjectRequest class (implementing RequestContext) that 
defines a save method. 

My question is how do I invoke the save method from the editor. It appears 
that after a driver.flush() I only have a RequestContext object to work 
with. That object only has the fire method, but I cannot tell it to use my 
save(project) method. When I invoke the requestContext.fire() method after 
doing a .flush(), the request factory appears to contact the server but 
nothing is persisted. Are there implied methods that the editor or 
RequestFactory is expecting to be implemented on the server? Should I be 
using the SimpleBeanEditorDriver instead?

My Editor: 

public class ProjectEditor extends Composite implements EditorProjectProxy 
{
interface Binder extends UiBinderHTMLPanel, ProjectEditor { }
private static Binder uiBinder = GWT.create(Binder.class);
@UiField
TextBox name;
public ProjectEditor() {
  initWidget(uiBinder.createAndBindUi(this));
}
}

 My workflow class:

public class ProjectAddPresenter extends
PresenterProjectAddPresenter.MyView, ProjectAddPresenter.MyProxy {
...
interface Driver extends
SimpleBeanEditorDriverProjectProxy, ProjectEditor {}
@Inject private CommonRequestFactory commonRf;
private Driver driver;
@Inject
public ProjectAddPresenter(final EventBus eventBus,
final MyView view,
final MyProxy proxy) {
super(eventBus, view, proxy);
this.view = view;
view.setPresetner(this);
driver = GWT.create(Driver.class);
}
...
public void edit() {
ProjectRequest request = commonRf.projectRequest();
ProjectProxy project = request.create(ProjectProxy.class);
ProjectEditor pe = view.getProjectEditor();
driver.initialize(pe);
driver.edit(project, request);
}
public void createProject(ProjectEditor projectEditor) {
RequestContext request = driver.flush();
request.fire(new ReceiverVoid() {
...
});
}
...
}

My ProjectRequest class:

@Service(value = ProjectDao.class, locator = DaoServiceLocator.class)
public interface ProjectRequest extends RequestContext {
  ...
  RequestVoid save(ProjectProxy project);
  ...
}

 Thank you.

[gwt-contrib] Re: Scripts and configuration to upload GWT bits to Maven repos (issue1520810)

2011-09-01 Thread t . broyer


This is a big step forward but:

 - none of the GAE POMs have dependencies, which is very strange.

 - many artifacts are already in Central, geronimo-* ones under the
org.apache.geronimo.specs groupId (e.g.
http://search.maven.org/#artifactdetails%7Corg.apache.geronimo.specs%7Cgeronimo-jta_1.1_spec%7C1.1.1%7Cjar
), jdo2-api at javax.jdo
(http://search.maven.org/#artifactdetails%7Cjavax.jdo%7Cjdo2-api%7C2.3-eb%7Cjar
) and datanucleus-* at org.datanucleus; so unless GAE requires modified
artifacts, there's no need to deploy them under com.google.appengine.

 - the push-* scripts call other scripts which are missing from the
review

[gwt-contrib] Re: Serialization of Final Fields in RPC (issue1380807)

2011-09-01 Thread stephen . haberman


Thinking about it some more; it would be the easiest if GWT just started
serializing final fields across the board, and only skipped them if they
were marked with a GwtTransient.

That is basically what the current patch does (except for ignoring sets
on the client-side).

Anything else requires making the server-side aware of the
rpc.final.serialize value. Maybe that is easier than I'm imagining.

Anyway, it'd be a breaking change, so perhaps it's not an option, but I
just thought I'd mention it.

There is a risk that existing users were relying on current behavior to not
send sensitive data in final fields across the wire, and changing it without
some form of opt-in seems a security risk.

It could be adding an inherits tag that sets a config property or
annotating service interfaces/etc, but it needs to be opt-in.

If the server needs to behave differently depending on this setting, then
either it should be included in the RPC payload or in some deploy artifact,
such as the serialization policy file.

It's fair to say that we are not sure how far one can go with this
release. It might be that you can already
build something useful with what we already have. The only way to be sure
is start hacking!

### Known issues

* Compilation is very, very slow.
* `scala.immutable.{TreeMap, TreeSet}` are not supported due to various
bugs (thus sorted collections don't work)
* many patterns in pattern matching logic are not supported (tough
issue) examples include
* pattern alternatives (`|`)
* guard patterns (`if` guard)
* GWT's development mode is broken
* We are compiling with all optimizations turned off. This results in a
slow and very large JavaScript code.

 to not send sensitive data in final fields across the wire

Agreed, that is the worst case scenario.

 such as the serialization policy file.

Yeah, my concern would be that the policy file is still somewhat
optional, right? At least personally I end up occasionally using the
legacy policy because I don't keep policy files across builds.

I suppose we could use the policy file if available, otherwise
default to the existing behavior.

In that regard, I'd encourage any GWT contributors interested in the

Greg sits next to the Scala guys at typesafe, but, other than Lex, we

We could alternatively bring up questions and issues here in

[gwt-contrib] less name mangling

2011-09-01 Thread Stephen Haberman

Hi,

One of the challenges we hit with scalagwt was source -
internal/binary name conversion being hueristic. Greg started a
prior discussion about this, with the summary basically being yeah,
it's a heuristic, and yeah, it's a problem.

To get scalagwt working in the least-hacky-way possible, I ended up
refactoring a lot of the source/internal name handling. We're concerned
it might be more changes to GWT core than you guys would be willing to
accept, so I'd like to outline my approach and see what you think.

If okay'd, it could potentially even be merged in prior to scalagwt, as
a separate/orthogonal cleanup of GWT. Which would probably make the
review process easier all around.

Anyway, the crux of the issue was BinaryName.toSourceName and friends. I
basically tracked down find-references on those and killed as many
as I could. I was mostly successful, except for deferring bindings,
which is still done by source names that are lossly converted from
internal names.

Per the last discussion, solving this problem really just requires
keeping two maps--one by source, one by internal or binary, and
then being able to look up either as needed.

Serendipitously, having two maps was mostly already being done, in
CompilationStateBuilder and TypeOracle. Only JProgram needed a
new/extra map.

So, the changes are, briefly:

1) Keying CompilationStateBuilder's allValidClasses by internal name
(that is what most clients had already)

2) Changed CompiledClass.getSourceName to be done deterministically by
probing instead of name mangling

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#L9R114

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#L5R105

It uses the inner class names as reported by ASM, which is stored in
CollectClassData:

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#L17R158

3) Adding methods to TypeOracle to do lookups by non-source names:

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#diff-2

This is probably the most controversial change. However, many clients of
TypeOracle were doing:

findType(InternalName.toSourceName(...))

So, TypeOracle was actively being used to do lookups by non-source
names, it was just not explicit in the API and something clients were
doing by hand. Adding the methods that I did allows clients to pass in
the names they have as in (be in internal/whatever) and TypeOracle will
handle the lookup deterministically (it has two (pre-existing) maps, one
by source, and one by internal).

findTypeBySourceOrBinaryName is particularly odd, but that is what
CompilingClassLoader needs:

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#L42R248

3) TypeOracleMediator lends it by-internal map to TypeOracle (which has
a by-source map), so that TypeOracle has both maps.

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#L16R351

4) JProgram gets a new map and requires the TypeOracle to look
up types by binary name to populate this new source name map.

https://github.com/stephenh/scalagwt-gwt/compare/stephenh:master...stephenh:scalagwt#L32R1038

---

So, in summary, yeah, this is a lot of changes. But a lot of name
mangling is gone and we've been using this in scalagwt with more success
than we had before.

I'd be glad to answer any questions, comments, concerns about the
approach. Obviously I'd really like to get it to the point of being
acceptable to GWT upstream (either the name cleanup by itself or
eventually with the rest of scalagwt).

Thanks,
Stephen

+#summary Notes on working with GWT, Maven, and Google Plugin for Eclipse
+
+This page is intended to serve as the canonical reference for working with  
Maven in the latest GWT and GPE releases. New releases of 3rd-party  
projects like Eclipse don't necessarily correspond to GWT releases, hence  
the need for a place to publish new notes independent of a release.

+
+wiki:toc /
+
+= Maven GWT Plugin =
+In order to include GWT in a Maven POM, you'll want  
[http://mojo.codehaus.org/gwt-maven-plugin/ Maven GWT Plugin], a  
third-party project with its own community support.

+
+= Sample Projects =
+The easiest way to get a GWT POM going is to snag one from of the GWT  
Maven sample projects below. There are currently issues with the  
gwt-maven-plugin archetypes, so a good starter POM is the best way to go  
until those issues are resolved.

+
+The GWT team maintains two sample projects using Maven in GWT trunk. These  
are

+
+ *  
[http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/expenses/  
Expenses sample]
+ *  
[http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/mobilewebapp/  
Mobile Web app sample]

+
+Several other Maven samples are available from the GWT community:
+
+ * [http://code.google.com/p/listwidget/ listwidget (App Engine,  
Objectify)]
+ * [https://bitbucket.org/gardellajuanpablo/gwt-sample/wiki/Home  
gwt-sample (Spring, JPA2)]

+
+= Using Maven with Google Plugin for Eclipse =
+[http://code.google.com/eclipse/index.html Google Plugin for Eclipse]  
(GPE) makes it easy to import Maven projects using GWT and App Engine. To  
get started, first
+[http://code.google.com/eclipse/docs/getting_started.html install GPE] and  
the additional Eclipse plugins required for your version of Eclipse:

+
+== Eclipse 3.5 (Galileo) and 3.6 (Helios) ==
+ # Install m2eclipse from update site  
http://m2eclipse.sonatype.org/sites/m2e
+ # Install m2e-extras from update site  
http://m2eclipse.sonatype.org/sites/m2e-extras

+
+== Eclipse Indigo Java IDE (*not* Java EE) ==
+ # Install m2e-wtp from update site  
http://download.jboss.org/jbosstools/updates/m2eclipse-wtp. Only one  
feature is required:

+ ** Maven Integration for WTP
+
+== Eclipse Indigo Java EE IDE ==
+ # Install m2e-wtp from update site  
http://download.jboss.org/jbosstools/updates/m2eclipse-wtp. The following  
features are required:

+ ** Maven Integration for Eclipse
+ ** Maven Integration for WTP
+
+After installing GPE and the required plugins for your version of Eclipse,  
you're ready to work with a GWT Maven project.

+
+== Configure a Maven project in Eclipse ==
+To configure an existing GWT Maven project, simply choose File | Import |  
Existing Maven project in Eclipse and browse to the project's pom.xml file.  
Google Plugin for Eclipse will automatically configure the project source  
folders and the GWT and App Engine SDKs if present in the POM. You can then  
run the project using Run as | Web application or by running Maven from the  
command line or the project's Maven menu.

+
+== Troubleshooting ==
+If you have problems importing a Maven project with Google Plugin for  
Eclipse, verify the following:
+ * You have installed the correct Maven helper plugins above for your  
version of Eclipse

+ * You have installed the most recent Google Plugin for Eclipse
+
+If a project has been imported correctly, you should see the following:
+ * Under project properties, Google  Web Toolkit, the Use Google Web  
toolkit box should be checked and Use specific SDK should point to GWT  
in your local Maven repository
+ * Under project properties, Google  Web Application, the This project  
has a WAR directory box should be checked and WAR directory should be  
src/main/webapp
+ * src folders should appear as Eclipse source folders in Package Explorer  
(except src/main/webapp, which will show as a normal folder)

+
+If project import fails due to a POM error, fix the error and retry the  
import as follows:

+ # Remove the project in Eclipse (but don't delete source folders)
+ # At the command line in the directory containing the POM, run mvn clean  
eclipse:clean

+ # Try the import again
+
+In most cases, after making a POM change in Eclipse, you should be able to  
right-click on the project, then click Maven  Update project configuration  
and/or Update project dependencies. However, the steps above are the surest  
way to pick up all changes.

I'd prefer this problem to be addressed in separate CL independent from of

At the time I was looking into this problem I was coming to similar
conclusions as Stephen did. They never materialized into clean patches,
though. This time it seems like we have a chance to fix it which would be
great.

+== POM changes needed for Eclipse Indigo ==
+Due to changes in the m2e Eclipse plugin for Indigo (3.7), plugin  
execution no longer happens directly, but rather must be configured through  
m2e's lifecycle-mapping plugin. In order for a plugin to be invoked within  
Eclipse, you must define a pluginExecution in the lifecycle-mapping plugin  
corresponding to the execution tag in the plugin definition itself. To  
achieve this, add a new section within the build section of the POM. The  
sample below shows the definitions needed to support maven-gae-plugin,  
maven-datanucleus-plugin (also for App Engine), and exec-maven-plugin,  
which is used by the new RequestFactoryInterfaceValidator.
