EMF Error

Trying to get RequestFactory to work but I am getting:

Server Error: Could not initialize class myproject.com.server.domain.EMF

at the line that contains this code:

List<Country> list = em.createQuery("select c from Country c").getResultList();

Anyone have any ideas?

Best Practise: Database Java Backend

Hi there,

maybe there were some answers serveral times on this topic but I
couldnt find them.

I am looking for a best practise of gwt project setup with java
backend.

As usual we are setting up our database first and then doing the
object relation mapping afterwards, creating DTOs and client classes.
For now this is a very manual job and we have to do mapping each time
by hand in jpa. This costs a lot of time and its redundant work(db
design and then design it again in orm).

Is there a better way to do this via Spring or Seam automaticaly?
Sorry but now I am a little bit lost what options I could use.

If this is the wrong group to ask please let me know.

Thanks for your help

Re: Action on a ImageResourceCell

I actually followed this tutorial and now it works fine: http://webcentersuite.blogspot.com/2011/03/custom-gwt-clickable-cell-with-images.html

Re: GWT CellList Drag and Drop

Hi,

Its working fine now. Because i have missed one jar file in class
path.
If you have time, please create an article about CellList re-order.

Thanks

Re: SplitLayoutPanel Sizing?

May be you are missing to put SplitLayoutPanel in a RootLayoutPanel.
Alternatively you can provide explicit size, see Recipes here:

Re: Using custom LocalMessages apart from Locales

An <ui:with/> translates into a GWT.create() call (unless you @UiField(provided=true) the field in your Java class). Because you're now GWT.create()ing the LocalMessagesFactory, you'll have to change you ui.xml files to <ui:with field="localMessage" type="net.company.project.common.widgets.client.i18n.LocalMessagesFactory" /> an then use it as {localMessage.get.foo} instead of {localMessage.foo}.

Re: GWT CellList Drag and Drop

Hi,
add draggable-plugin-1.0.4, remove gquery-dnd-bundle-1.0.3. If you're
not using Maven move droppable-plugin-1.0.6 before gwt 2.3 library in
compilation order. Hope it helps.

Luca

Re: Using custom LocalMessages apart from Locales

Hi Thomas,

thanks a lot! I've tried your advice right now and it works absolutely fine for all cases where we can inject the LocalMessages.

There is only one problem since we also use the LocalMessages within the UiBinder xml templates. There we currently reference the LocalMessages as a resource to the common LocalMessages interface like this:

<ui:with field="localMessage" type="net.company.project.common.widgets.client.i18n.LocalMessages" />

But this reference seems to be used / executed before the <replace-with> tags are parsed and GIN is executed?

Is there a possible solution to enable GIN also working in that case?

Best regards and thanks again for your help

Tim

Re: GWT CellList Drag and Drop

You are using an old version of gwtquery.

Download the last stable version of GwtQuery compatible with the gwt
version you are using : http://code.google.com/p/gwtquery/wiki/Downloads
The last version of the draggable plugin :
http://code.google.com/p/gwtquery-plugins/downloads/detail?name=draggable-plugin-1.0.4.jar
The last version of the droppable plugin compliant with the gwt
version you are using :
- for gwt 2.2 : http://code.google.com/p/gwtquery-plugins/downloads/detail?name=droppable-plugin-1.0.5.jar
- for gwt 2.3 : http://code.google.com/p/gwtquery-plugins/downloads/detail?name=droppable-plugin-1.0.6.jar

Put these 3 jars in your classpath and it's should work.

Re: Using RequestBuilder to communicate with a RESTful API on another port

If you do not have server-side code in Java, then you can just start the DevMode in -noserver- mode and point it to your "Go" server, see http://code.google.com/webtoolkit/doc/latest/DevGuideCompilingAndDebugging.html#How_do_I_use_my_own_server_in_development_mode_instead_of_GWT's

Otherwise, you can deploy a "proxy servlet" in the embedded Jetty server, see http://code.google.com/p/google-web-toolkit/issues/detail?id=3131

Using RequestBuilder to communicate with a RESTful API on another port

I want to write a RESTful GWT frontend for a RESTful backend. The
problem is that the backend code (server) is written in Go and can't
run on the same port as GWT's dev server (port 8888 & 9997).

Due to XMLHttpRequest's (the underlying class behind RequestBuilder)
security restrictions I can't communicate with anything that isn't
running on the same port of the same host? Of course I can write GWT
frontend code, compile it and run it on the same host&port but this
dev approach isn't really feasible as I can't test anything while I'm
in dev mode.

So is there a way to make REST calls (via RequestBuilder or
XMLHttpRequest) to a server that isn't running on the same host&port?

Re: how do i add a tooltip to a column header in a celltable ?

hmm looks like i needed to use the new signature of the method :

public void onBrowserEvent(Cell.Context context,
                               Element elem,
                               DemandeBean object,
                               NativeEvent event) { ...}

However the method is called only if i click in the column.
It is not called if i just move over the mouse.
That's one thing.
Another thing is that I want the tool tip only when the user moves the mouse over the column header, not the entire column.
Any idea ?
Thanks

Re: Big Daddy example problems

Can the application runs in other port??

2011/5/30 Zachariah Young <zpyoung@gmail.com>

@bbgott

I'm getting the same issue also on Ubuntu. The solutions work just fine on Windows. Could it be that Ubuntu has the 8888 port blocked or something?

Also what did u hard code to get the Android application to work.

Re: Overriding a css style loclly

Hi lalit, try it with this

<ui:style field='reportStyle'>
@external gwt-Label;
.gwt-Label{ color: #000 !Important; }
</ui:style>

I founded it here

2011/5/30 lalit <lalit.bhatt@gmail.com>

I have a lot of labels in my application.I have overriding the style
as most of the place, I need the new style and it works fines. the
overridden style is

.gwt-Label {
font-size: 15px;
font-weight: bold;
color: #fff;
float: inherit;
}

However at one particular place I need the color of label to be black,
so I was trying to override the style in that ui.xml locally like

<ui:style field='reportStyle'>
@external gwt-Label;
.gwt-Label{ color: #000; }
</ui:style>

However this impacts the style of label at other places also. Is there
a way to override the standard style in a ui.xm so that it impacts the
widgets of only in that ui binder.

thanks in advance,

Re: Canvas dimensions

Hi Cheers,

I read long ago according to where the application runs for certain parameterschanged the settings.

GetOffsetWidth I think is one of them.

Can it be?

2011/5/31 Thomas Lefort <leforthomas@gmail.com>

Hi,

I have a canvas in a hidden panel. It is created before the panel is
made visible. The problem I'd like to set its DOM width to 100% but I
have a problem with the setCoordinateSpaceWidth then as I cannot get
the canvas dimension via getOffsetWidth as the canvas is not visible.
I don't even think I can add a resizeevent to Canvas nor is there a
VisibleEvent. Would appreciate if anybody had an idea as to how to
circumvent the problem?

Cheers,

Thomas

Re: gwt servlet thread, timer,reload

Hi Arno,

I have relatively little experience in this, but if you want some action program for xtime, gwt offers mechanisms for such coordination.

I would recommend that you take a look at Timer.

My philosophy is that if there is already a thing made by Google, no one will do better than them.

I hope it's what you want.

you can start your timer-process from something which starts with your webapp, for example in a ServletContextListener-implementations init method
