There isn't any way to host an entire website on AppEngine is there?
It doesn't seem like it, I just thought I'd ask. So if that's the
case, how am I supposed to integrate GWT into my application? an
iFrame? Does GWT have any write-ups about this? What if I need the
rest of my website to have access to the same database my application
is using. Is my only option at that point alternative hosting?

What if I want my entire website to use GWT components, and a GWT RIA
integrated into a specific part? That's what I'm trying to accomplish,
and I don't know javascript worth squat, so what am I supposed to do?
I need the entire site to have access to the database, so I'm thinking
about buying hosting, and using my-sql as my db, but I'm not sure what
hosts can run gwt server side applications either. Any information you
guys have or experiences with this would be great!

Re: Hosting Entire Website on AppEngine? Integrating GWT into your website?

Joe,

Thanks for your fast reply. I figured you'd have you use google's
database solution, but I thought it was called datastore. Either way
I'm fine with that as long as it works, however using multiple less
than operators across multiple entities would be convenient.

One of my questions was how would you have a gwt application (or
applicationS) spanning multiple html files, however you have your
entire website it seems on a single html file. I'm not sure how you
did that with your GWT app, but I'm gonna look through your source
code and see if I can't figure out how. Through doing that, AppEngine
is able to host your entire website, which is what I'd like.

I actually have a good portion of my GWT app written. I've got RPC
calls working, and I have the ability to use JDO, and make objects
persistent, however I've been getting weird errors, and haven't been
able to get my queries to work once. So I started thinking about other
things and these questions started coming to mind. I thought that if I
wasn't going to be able to host my site completely on app engine, why
would I even bother with this, and not just use SQL? So apparently I'm
going to keep chugging it out with AppEngine. Thanks!

 Hi Scott,

 That is what I am doing withhttp://www.gwtmarketplace.com.  The catch

 You need to register an app engine account and then register a google

 account to that domain.  You can browse the source code for
 gwtmarketplace here if you are

 I am using Objectify (http://code.google.com/p/objectify-appengine/)
 as the data access utility but you could also use JPA as well.

 As far as what hosts can run GWT - a simple web server like Apache can
 do that as your GWT application will be compiled to static recources
 to be served.  You will still need servlets or some other mechanism
 for data access - I use servlets with RPC calls (http://

 Hope this helps...

UIBinder + DOMHandler?

Hey guys, I know that UIBinder disables DOM Events, but I have an
application that uses DOM Handlers in order to tell when a mouse up
event, or mouse over event has taken place on my grid, and what cell
it took place with. The issue is that since UIBinder disables DOM
Events, I can't get my DOM handlers to work either. I'm making an
application with GWT, that I'd like to use UIBinder, but there is this
one part of the application that will being used maybe 10% of the time
that requires DOMHandlers to work until GWT adds more mouse event
options for Grid. Is there any way that I can get UIBinder to work for
most of my program, but for part of my program get it to work through
building the UI with function calls?

Or perhaps is there a way to get my dom handler to work with UIBinder?

Any help at all, or even ideas would be great! Thanks!

Re: Hosting Entire Website on AppEngine? Integrating GWT into your website?

Thank you very much for your replies earlier today. Due to the link to
your app (and even the source code!), you've completely changed/
corrected my view of how GWT is supposed to be used. I was stuck in
the PHP mindset of multiple websites, and I've read that GWT is used
to make Rich Internet Applications probably 15 times, but I didn't
really understand how it was supposed to fit together until I saw your
app, so thank you very much.

 As far as the multiple files, you can have as many GWT application
 files as you  want - the each require an EntryPoint class though.  And
 if you want just plain static files and resources, you can do that as
 well... you would just put them directly under the war directory of
 your application.  One thing to note - AFAIK, you can't make a change
 to a single resource and upload that - you have to upload the whole
 site again.  But, google has a nice versioning system so you can
 upload multiple versions of your app to test and then move a version
 to the default version when you are ready.

Exception while dispatching incoming RPC call Object Manager has been closed (repost)

Hey, I've been trying to get my RPC Call to AppEngine to work since
last Wed, with no luck. My issue now seems to be with my query. I'm
willing to post any code needed, but I just want to get this working,
as this has completely halted me on any further progress on my app.
Everything looks like it should be working. Here is my
TestServiceImpl.java :


package com.spierce7.gwt.test.server;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.logging.Logger;

import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManager;
import javax.jdo.PersistenceManagerFactory;
import javax.jdo.Query;

import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import com.spierce7.gwt.test.client.TestService;
import com.spierce7.gwt.test.shared.PersistentShift;

public class TestServiceImpl extends RemoteServiceServlet implements
TestService{
private static final Logger LOG =
Logger.getLogger(TestServiceImpl.class.getName());
private static final PersistenceManagerFactory PMF =
JDOHelper.getPersistenceManagerFactory(transactions-optional);

public void addShift(Date startDate, Date endDate) {
PersistenceManager pm = getPersistenceManager();
try {
pm.makePersistent(new
PersistentShift(startDate, endDate));
} finally {
pm.close();
}
}

public ListPersistentShift getShifts() {
PersistenceManager pm = getPersistenceManager();
ListPersistentShift results = new
ArrayListPersistentShift();

Query query = pm.newQuery(PersistentShift.class);
query.setFilter(search == 1);

try {
results = (ListPersistentShift)
query.execute();
} finally {
pm.close();
}
return results;
}

private PersistenceManager getPersistenceManager() {
return PMF.getPersistenceManager();
}
}

___

My addShift function works fine, and I can add objects to the database
just fine. I just can't retrieve them. I finally changed the objects
in the database to all have an int variable called search, and it's
always set to 1. When I call the getShifts() method though, it gives
me this error:

javax.servlet.ServletContext log: Exception while dispatching incoming

... (it goes on)

I saw some examples where queries are ended with query.closeAll(), and
I tried that also, but I get a different error telling me something
couldn't be serialized from the datanucleus. At this point I just want
it to work. Any help, or any ideas would be great. Let me know if
you'd like some other code posted.

Re: onModuleLoad() Before Page Load

I'm not familiar with a lot of the things that you are using, however
GWT has a method that it calls after the widget that the method is
attached to is loaded. It's called onLoad(). Typically, when I've used
it in the past, it's because I was extending a widget, say a Grid, and
then I would override the onLoad() method. I'm not sure how you would
implement it into a completely custom widget though. You might be able
to put the iframe in a HTMLPanel or something, and call the onLoad()
method. Either way, I think this may be what your looking for. Hope
this helps!

On Aug 6, 9:54 pm, Ryan McDonald ryan.mcdona...@gmail.com wrote:
 To my understanding, the compiled GWT file module-name.nocache.js
 blocks page evaluation when it is loading. When it finishes, it
 creates a hidden iframe that begins to load the module-name.cache.js
 file but it does NOT block page evaluation and loads asynchronously.

 In my GWT module I define a native Javascript function using JSNI that
 adds a widget to the page.

 I use a Velocity Template that dynamically generates divs with unique
 ids, then call my Javascript method that I defined using JSNI to
 attach the widget to the specific div.

 The problem is that when my page is loading, and the Velocity Template
 calls my Javascript method, the hidden iframe has not finished loading
 the module-name.cache.js that defines the method.

 Is there a way to make the module-name.cache.js file load
 synchronously so that it will block page evaluation until it finishes
 loading? Or make onModuleLoad() run before the page loads completely?
 Something along these lines?

Re: bug in Animation class

I'm going to be delving into the animation world in the next few
weeks. Thanks very much for this. I'll try to keep this in mind if I
have any issues.

On Aug 6, 11:24 am, Michael michael.vill...@gmail.com wrote:
 Hi,

 I didn't see a place to post bugs, so I am submitting it to the group.

 I've been working with GWT for a one off project on our 
 website,www.studyisland.com. I was attempting to use the Animation class (in
 package com.google.gwt.animation.client) and could not figure out a
 way to get an animation of an Image object to replay when I clicked on
 it. I tried both rerunning the original Animation instance recreating
 the instance and attempting to run it. My code is identical to the
 example in the GWT showcase, with the exception that I create 3 unique
 animations, one for each image on the page.

 The showcase animation can be replayed, but in my case, where 3
 animations existed the animations could not.

 Digging into the Animation class, it is obvious why this is by the
 line of code in the method run(int duration, double startTime):

 // Restart the timer if there is the only animation
     if (animations.size() == 1) {
       animationTimer.schedule(DEFAULT_FRAME_DELAY);
     }

 So, you can't re-run an animation if you create more than one
 animation instance on your page. Thats fine, there may be some
 limitation that I'm unaware of to prevent this. I'll just reset the
 Animation class back to its initial state and start over... but I
 can't because the animations are driven by an array called
 animations that is a private static member of the class, and there
 are no accessible methods to reset it.

 Fortunately the easy solution for me is to just copy all of the code
 in the Animation class into a new class, and add a method
 resetAnimations to take care of this.

 public static void resetAnimations() {
   animations.clear();
   animations = null;

 }

 I just call this before re-running any animations, and everything
 works fine.

 Now, I consider myself pretty good with Java, but I'm not a javascript
 expert so I can't say for sure whether doing this is safe or why the
 original programmers didnt include this functionality initially.
 However, I think it very likely that there will be other GWT users in
 the future who might encounter this issue, hence I think it should be
 addressed.

 If you have any questions about my writeup here, or would like some
 code or something like that, feel free to email me:
 michael.vill...@gmail.com.

 I'm loving GWT by the way. Thanks to everyone who has contributed!
 -Michael

Re: Cell click events for incubator's FixedWidthGrid

Are you only wanting to tell if a cell was clicked, or are you wanting
to use specifics, such as the MouseUpHandler, MouseOverHandler, etc.?

If you are using the Grid and all you want to do is tell which cell
was clicked, Grid has a function called addClickHandler() (only works
with the click handler to tell if it was clicked), and you can use the
getCellForEvent() method to retrieve the actual cell object, and from
there call the methods (I think getRow(), and getIndex()), to get the
row and column that it's in.

If you want to do MouseUp handlers etc, shoot me an e-mail and I can
help you with that. That's a bit more convoluted.

On Aug 7, 7:55 pm, Strannik outofvo...@gmail.com wrote:
 Hello,

 Does anyone know how to figure out which cell was clicked on in the
 FixedWidthGrid from the gwt incubator?

 Using grid.addTableListener(...) seems to be deprecated a while ago
 and does nothing (it probably worked in pre gwt-1.6).

 The GWT API reccomends to use:
 HTMLTable.getCellForEvent(com.google.gwt.event.dom.client.ClickEvent)

 however the incubator FixedWidthGrid extends it's own HTMLTable which
 does not even support adding click handlers.

 It is still possible to use .addRowSelectionHandler(..) though that
 does not appear to tell you which cell on a row was clicked.

 Thank you

Re: GWT Popup Menu - Close on losing focus

Are you wanting it to close when you lose focus, or simply when your
mouse exits the panel? In my mind, the popup would lose focus when
you actually click outside of the popup, rather than just moving the
mouse out of it. I'm going to address the question in regards to your
mouse exiting the panel as it would be the more difficult thing to do.

I'm not sure what you are using for a pop-up method, but I would
recommend taking a look at the MouseOutHandler, and the
MouseOverHandler. I would add a MouseOutHandler to the popup, so if
they moved the mouse out, it would call a method where you could close
the popup. Another way to do this is if when the popup comes up, you
could create an invisible panel that is in front of your entire
program, but still is behind your popup popup, and give it a
MouseOverHandler so that whenever it is moused over (meaning whenever
you mouseover any part of your program that is not your popup) it will
call a method, that you can have close the popup. Something I'd
consider beforehand is, what if their mouse is not in the popup when
it's created, then it will close really really fast before they have
time to read it. You would have to make sure they mouse over the popup
prior to it being able to close.

If you wanted to do it the focus way, I'd do the latter method listed
above, but rather than using a mouse over handler for the invisible
panel, I'd use a mouse click handler, or MouseDownHandler.

If you are new to GWT Events, I'd recommend taking a look at the
following links:

http://code.google.com/webtoolkit/doc/latest/DevGuideUiHandlers.html

I saw some examples where queries are ended with query.closeAll(), and
I tried that also, but I get a different error telling me something
couldn't be serialized from the datanucleus. At this point I just want
it to work. Any help, or any ideas would be great. Let me know if
you'd like some other code posted.

Transferring data from client to server: Do extra methods add more information that is sent to the server?

If I'm transferring an object that has some persistent data in it to
be saved on the server, from the client to the server (or vice versa),
does me having extra methods in the object, increase the amount of
data transferred between the server and the client? What about extra
variables that are not persisted?

Re: Please help - GWT application will not load in IE!

I hate issues like this. Unfortunately, particularly since GWT is
young, I've gotten something working in one browser, only to find it
doesn't work in another browser. Typically I just find a more common
way of going through something.

What I'd recommend is (although it's time consuming), is to comment
out the method that builds your entry GUI, and start adding stuff back
slowly until you get the issue. Try to get it down and figure out
exactly what isn't able to load in I.E. The fact that nothing is
loading makes me think it might be one of the outside layers, perhaps
try some inner layers of the GUI and see what works and what doesn't.

If I got your code, that's what I'd end up doing any ways. Errors like
this can just happen for random reasons, and to my knowledge there
isn't a well this works in all the other browsers, but not I.E.
error. Google has been good about fixing those if I'm not mistaken.

Alright, so I tried RootLayoutPanel.get() instead of RootPanel.get()

Not sure if that helps... Will keep looking for answers - but please,
if you require any more information to try and help me solve this just
ask away!

Other information I can give you is I am using the MVP design pattern
as suggested by the GWT team based off their contacts example. So
while I don't necessarily call
RootLayoutPanel.get().add(myMainLayoutPanel)) directly I do set
RootLayoutPanel.get() as a container and then later add the
myMainLayoutPanel to it. Comes to the same thing I suppose. Just
trying to think of anything that may help!

Thanks!

Maybe it's just me, but it's kind of hard to tell from your description what
could be wrong.

I do see that you're using RootPanel mixed with LayoutPanel. Try adding the
LayoutPanels to the RootLayoutPanel (something like
RootLayoutPanel.get().add(myMainLayoutPanel)).

Also, I assume you compiled your app for the IE permutation(s)?

Hi there,

Can somebody please assist me - I have spent the last 3 months writing
a GWT application and I cannot get it to work in Internet Explorer.
It's my first GWT application. It works fine in Firefox and Chrome. In
internet explorer it just doesn't load up.

Here are some details:

I am using GWT 2.0.3 developed on Ubuntu 9.03 using Eclipse. At first
my application was loading from a div tag deep within the DOM's body
tag - it was like this because I was making use of html and css to
build a friendly border around the app. All that would happen was
that the html and images would all load - but my app wouldn't show. I
have now since moved the application to use the RootPanel.get() so
that it loads straight from the body tag - no luck, nothing loads up
at all.

While my app is simple, it contains a lot of panels within each other
to build the layout, the main panel being a LayoutPanel. I have tried
it in quirks-mode and standards-mode and both don't seem to work.

Another problem I was having which seems to have gone away I described
on this post on StackOverflow:

http://stackoverflow.com/questions/3033073/gwt-in-ie8-exception-throw...

Please can somebody help me. I have already posted on this forum and
received no help. If anyone has any ideas, or suggestions - I really
will be appreciative! I can also provide the link to the site on
request.

Thanks in advance - if anyone actually sees this.

Xandel

Re: add mouse handlers for document body?

What do you mean by document body?

You might want to look into a DOMHandler. That's how I got mouse move
handlers to work on my grid. Grid's don't have an obvious method that
allows you to add a MouseMoveHandler like a lot of other things do
(grids only have addMouseClickHandler). I'd take a look again at what
you want to add the handler too and make sure it doesn't have an
obvious method like that.

Another option is wrapping things in an HTMLPanel, which would allow
you to add a MouseMoveHandler, etc.

 Hi,

 I have a question on using css in gwt.

 I know you can give the ui:style component a src to a css file.
 But what if you want to use the css that is linked in the html page
 from which the javascript from the gwt project is called?

 i tried this:

 g:Button addStyleNames=action ui:field=btnSearch/g:Button

 And in the css file from the host html page i have put:

 .action {
    background-color: green;

 }

 Is this possible?
 Because our javascript that was compiled is called from other html
 pages to.

 kind regards,
 Thomas

Error Doing RPC Call with my own return type: org.datanucleus.exceptions.ClassNotResolvedException

Hey, so I can save data to app engine in an entity of type
PersistentShift, a class I made to save shift information. I've got
2 objects I'm saving within the class. Both are Date objects. One is
startDate, one is endDate. I wanted to be able to query the server,
and have a return type of PersistentShift. In order to do this it was
recommended that I put my Persistent shift class in the Shared
package, as opposed to having one in the client package, and one in
the server package. I've done this, and got it to where I can save
data again, but now I'm getting an error when I try to query that
data. Below is the relevant code. My code compiles with no errors:


package com.spierce7.gwt.scheduler.client;

public class Scheduler implements EntryPoint {

private final SchedulerServiceAsync schedulerService =
GWT.create(SchedulerService.class);
public boolean timerSet = false;


public void onModuleLoad() {
//Date startDate = new Date();
//Date endDate = new Date();
//endDate.setHours(endDate.getHours()+1);

//addShift(startDate, endDate);

loadShifts();

}

private void loadShifts() {
schedulerService.getShifts(new
AsyncCallbackListPersistentShift() {
public void onFailure(Throwable error) {
Window.alert(error.getMessage());
}
public void onSuccess(ListPersistentShift results) {
Window.alert(Shift Retrieved Successfully!);
}
});
}
}

==
package com.spierce7.gwt.scheduler.shared;

@PersistenceCapable(identityType = IdentityType.APPLICATION)
public final class PersistentShift implements IsSerializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
public Long id;
@Persistent
public Date startDate;
@Persistent
public Date endDate;

public PersistentShift() {}

public PersistentShift(Date startDate, Date endDate) {
this.startDate = startDate;
this.endDate = endDate;
}

}

===
package com.spierce7.gwt.scheduler.server;

public class SchedulerServiceImpl extends RemoteServiceServlet
implements SchedulerService {
private static final Logger LOG =
Logger.getLogger(SchedulerServiceImpl.class.getName());
private static final PersistenceManagerFactory PMF =
JDOHelper.getPersistenceManagerFactory(transactions-optional);

public void addShift(Date startDate, Date endDate) {
PersistenceManager pm = getPersistenceManager();
try {
pm.makePersistent(new PersistentShift(startDate, 
endDate));
} finally {
pm.close();
}
}

public ListPersistentShift getShifts() {
PersistenceManager pm = getPersistenceManager();
ListPersistentShift results = new 
ArrayListPersistentShift();

try {
//Query query = pm.newQuery(PersistentShift.class);
//query.setFilter();
//query.declareParameters(SchedulerDate startDate 
SchedulerDate
endDate);
//query.setOrdering(startDate);
Query query = pm.newQuery(SELECT * FROM 
PersistentShift);
results = (ListPersistentShift) query.execute();
} finally {
pm.close();
}
return results;
}

private PersistenceManager getPersistenceManager() {
return PMF.getPersistenceManager();
}
}

===

My server is calling the get shifts method, and this is the error I'm
getting:

org.datanucleus.store.query.AbstractJDOQLQuery init: Candidate class
for JDOQL single-string query (PersistentShift) could not be resolved
