The fact that it works when in Hosted mode in IE, but not when it's
deployed is making me think it is a security thing. I'm just not sure
the work around. I've tried various security settings, but can't get
it to show up. THe path looks right to the clear cache, not sure waht
else could be messing this up. Cause it looks like it's putting the
correct image sizes (Things next to it are pushed over correctly).

Very peculiar. I've even noticed that Tree +/- are missing as well as
disclosure panel's arrows. So it's not just my image bundles, but
GWT's are having a hard time. Very confusing. I'll keep playing with
it, see if I can figure something out.

 It could be two things:
  - a bad path to the bundle (IE is known to have some bugs re.
 resolving relative paths, though it shouldn't affect ImageBundles; but
 maybe if you're playing with the paths when deploying your app)
  - ImageBundles use an ActiveX (filter: AlphaImageLoader), so it might
 really be a security thing.

Export GWT app as WAR file - EASY tutorial for this?


Hi,

I want to export my GWT app as a WAR file and deploy it on a tomcat
server. I've read dozens of threads about this topic, and I understood
nothing. I do not know anything about WAR files, ANT build scripts or
tomcat server, I'm totally new to that stuff. I tried to figure it out
by myself, but I couldn't get past the first few steps. When I right-
click my GWT project in eclipse and select export/web/WAR file, it
always says Module name is invalid when it asks for a web project
name. What to do now? Can someone give me a really basic instruction
for this, or a good link to a tutorial? I'm really confused by this, I
need to know the very basics.

Thanks a lot in advance!

Cell width in DockPanel

2009-07-20 Thread badgerduke


Hello:

I have the following code in a DockPanel:

this.add(mainEastPanel, DockPanel.EAST);
this.add(mainWestPanel, DockPanel.WEST);
this.add(mainSouthPanel, DockPanel.SOUTH);
this.add(mainNorthPanel, DockPanel.NORTH);
this.add(mainCenterPanel, DockPanel.CENTER);
this.setCellWidth(mainWestPanel, 100px);
this.setCellWidth(mainEastPanel, 100px);
this.setCellWidth(mainCenterPanel, 800px);
this.setCellWidth(mainNorthPanel, 800px);
this.setCellWidth(mainSouthPanel, 800px);


This code changes the style attribute on the cells.  But the cells
still have 'width= height=' which is negating the style attribute:

td width= height= align=left style=vertical-align: top; width:
800px; colspan=1table cellspacing=0 cellpadding=0tbodytr/
/tbody/table/td

How do I get rid of the width and height attributes?  Thanks.

Re: Automatic Testing

2009-07-20 Thread Carl Pritchett


We are testing our app with Selenium. I've written some wrappers from
common components (only for GXT at the moment) and also common actions
like select tree item x etc. I'm setting Id's on components of
interest.The balance is to write locators (XPath) that are specific
enough with out being fragile.

The tests are running reliably, although they are quite slow so we've
kept these integration and acceptance tests to a minimum. As unit
tests are much faster, we separate all controller and view code so
we can test with plain junit / EasyMock.

 To add temporary DOM IDs which only appear for testing (which will

Re: JSNI issues

2009-07-20 Thread Adam T


Hi,

It might be the case that in both cases your GWT code is loaded and
executing before the browser has loaded your externally referenced
JavaScript file.  To remove that possiblity, you can place the
script tag you have in the HTML into your module's .gwt.xml
definition, i.e.

module
   inherits name='com.google.gwt.user.User' /
   script type=text/javascript src=protovis.js
/module

With this sett up, the GWT boostrap code should ensure the library
JavaScript is loaded before your GWT code executes.

Re: Export GWT app as WAR file - EASY tutorial for this?

2009-07-20 Thread Chad


Martin,

It can depend on your version of GWT. If you are using the GWT-Eclipse
Plugin (GEP), you can just click the GWT Compile button from the
toolbar. After it compiles successfully, open your project folder
(outside of Eclipse). You will see a war folder inside your project
folder. Open that war folder. You will see a few files and folders.
Select everything and create a zip file (this should be a right-click
action). Name the zip file something.war and that's it. When you drop
that war file into your Tomcat webapps folder, it will get
automatically expanded into a folder named the same as the war file
name (without the extension).

If you are using an older version of GWT, then the manual steps I
outlined a while back may help and can be found:

Re: Export GWT app as WAR file - EASY tutorial for this?


Hello Chad,

I'm using GWT 1.6.4 with the Google plugin for Eclipse.

thank you very much, it worked fine. Great! Unfortunately, I can't get
my application to run. My RMI call fails on the server. When I look
into the tomcat server logs, it says:

com.google.gwt.user.client.rpc.SerializationException: Type
'java.rmi.UnmarshalException' was not included in the set of types
which can be serialized by this SerializationPolicy or its Class
object could not be loaded. For security purposes, this type will not
be serialized.

My server code tries to connect to a remote service. In hosted mode,
it works fine. But not when my application is deployed. Why is an
UnmarshalException being thrown? How can I debug the server-side code
with tomcat? After some research, I found out that it's possible to
debug tomcat java code, but apparently, it's so complicated that I'm
not able to do it. Unfortunately, I haven't found an easy tutorial for
this. Can someone give a little hint on how to do this?

Re: Dose GWT 1.7 support debug on java 6?

2009-07-20 Thread Rajeev Dayal

Hi,
Downgrade to JDK 1.6.0_13. As Paul mentioned, there is a known issue with
debugging when using JDK 1.6.0_14.

Also, the issue does not have to do with the JDK that you use to compile
GWT_TRUNK with - it has to do with the JDK that you're using when you're
debugging your application. So, make sure that the JDK associated with your
project in Eclipse is NOT JDK 1.6.0_14.

Re: Image Bundle not working in IE

2009-07-20 Thread Rajeev Dayal

It is odd that it works in hosted mode, but not in web mode - because the IE
settings (security even) should be the same for IE6 hosted mode, and the
normal IE6 browser.
Actually, here is one thing you can test - try hitting your deployed app
with the hosted browser. Launch hosted mode with the -noserver option, which
will prevent GWT's default server from starting up. That way, we can
determine if this is an issue with the hosted browser, or something wonky
with your deployment.

On Mon, Jul 20, 2009 at 11:59 AM, Sean slough...@gmail.com wrote:


 The fact that it works when in Hosted mode in IE, but not when it's

 the work around. I've tried various security settings, but can't get
 it to show up. THe path looks right to the clear cache, not sure waht
 else could be messing this up. Cause it looks like it's putting the
 correct image sizes (Things next to it are pushed over correctly).

 Very peculiar. I've even noticed that Tree +/- are missing as well as
 disclosure panel's arrows. So it's not just my image bundles, but
 GWT's are having a hard time. Very confusing. I'll keep playing with
 it, see if I can figure something out.

Add external java project to GWT project in Eclipse


Hello,

my GWT server-side code needs an external java project. I have added
the project under Configure build path / Projects. It works fine in
hosted mode. But when I deploy my application on a server, I get lots
of ClassNotFoundExceptions. Obviously, GWT cannot find the external
java code. When I look at the war\WEB-INF\classes folder, I see that
the external java classes have not been included.

How can I get GWT to include the external classes?

Re: Add external java project to GWT project in Eclipse


Hello Sean,

thank you very much. I've thought of that solution too, but it is not
appropriate for my GWT project. I have to add 4 external projects to
my GWT project, and all of these 4 projects are subject to change
every day. It would be too much work to export them to a jar file
every day. Is there some way to automatically add the external project
sources to the GWT output folder?

Re: JSNI: window vs $wnd

2009-07-20 Thread Darth

It's explained here:
http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideJavaScriptNativeInterface
Right after the first example.

window = host page
$wnd = the nested iframe page where your scripts reside

From the tutorial you cited, I'm not sure why it doesn't work when
using $wnd. Maybe the nested page can't write to the host page?

Cheers,

What is the best way to enable save/apply button on TextBox edit

2009-07-20 Thread Bakul


Hi,

I have added:

 myTextbox.addChangeListener(new ChangeListener(){
public void onChange(Widget sender) {
onEdit();
}
});

and onEdit() I am enabling Save/Apply button.

Problem:
ChangeListener() get fired when myTextbox loses the focus. So when a
person start typing on myTextbox, he is done with entering data but
save/apply button is still not enabled as still focus is on myTextbox.

If I goes and add KeyBoardListener and try to handle it on onKeyDown
(), for which keyCode I should fire onEdit() which enables save/apply
button. I mean it should not be enabled if person press up/down/left/
right arrow key or any function key or insert/delete key and many
more.

Is there any known solution to handle this problem?

Thanks,
Bakul.

if (text.getText().length() != 0) {

Determining a specific cell in a FlexTable

2009-07-20 Thread jeffdonthemic


I'm working on my first project using the FlexTable and am developing
a time entry POC. Essentially users can click a button to add a new
row to the entry screen, select a project for that row and then enter
time for 7 days. I then total the 7 days for the line and then sum all
of the lines for a grand total. Not rocket science.

I'm using a few handlers to determine which cell and row the user is
currently entering time for but it seems like a hack. Is there an easy
way to determine which widget in the FlexTable (row x, column x) the
user is currently interacting with?

Thanks!

Is GWT's compiler java-javascript or java bytecode - javascript?

2009-07-20 Thread Mathijs


Hello,

I would like to know at which level gwtc works. Is it purely at the
source level (.java) or more low-level (bytecode)?
I'm a ruby developer, using jruby (which runs on JVM). jruby is able
to compile ruby code to .class files. Also, I'm able to interact with
other java libraries, so in theory, I should be able to use the GWT
classes from ruby.
I would like to use GWT, but I don't want to switch to java. If GWT's
compiler would be able to process the .class files jruby creates for
me (without having a .java source file) this would be very cool.

Googling didn't turn up much for this subject so I'm affraid I'm out
of luck.
Thanks for any help

gwt:run command, I get the window of the hosted mode.
Is there a configuration to do?
Thank you!

Re: JSNI issues

Adam, I added

No change!

 Hi,

 It might be the case that in both cases your GWT code is loaded and
 executing before the browser has loaded your externally referenced
 JavaScript file.  To remove that possiblity, you can place the
 script tag you have in the HTML into your module's .gwt.xml
 definition, i.e.

 module

    script type=text/javascript src=protovis.js
 /module

 With this sett up, the GWT boostrap code should ensure the library
 JavaScript is loaded before your GWT code executes.

map, add marker and remove marker

2009-07-20 Thread Irwan Hendra


Hi

I'm new with GWT so please bear with me
I'm using GWT EXT and openlayer map, i'm using mapPanel to display map
and markers on it

following example from here:
http://abhijeetmaharana.com/blog/2008/04/07/gwt-ext-and-google-maps/

however, when i tried to remove the markers using
mapPanel.removeAllMarkers() all markers got removed fine, except it
doesn't purge the memory used, so in the end the browser (both ie and
firefox) used up 1gb memory and then crashed

I know this should be posted in GWT-EXT forum, but for some reason I
never received activation email from them, so I have no choice


please help thanks

Re: Is GWT's compiler java-javascript or java bytecode - javascript?

It uses the source code, not the bytecode. It can't be made to work at

 I'm a ruby developer, using jruby (which runs on JVM). jruby is able
 to compile ruby code to .class files. Also, I'm able to interact with
 other java libraries, so in theory, I should be able to use the GWT
 classes from ruby.
 I would like to use GWT, but I don't want to switch to java. If GWT's
 compiler would be able to process the .class files jruby creates for
 me (without having a .java source file) this would be very cool.

 Googling didn't turn up much for this subject so I'm affraid I'm out
 of luck.
 Thanks for any help

Re: JSNI issues

2009-07-20 Thread Adam T


It could still be a similar thing; I'm not 100% clear what you are
trying to do above, but it looks like your steps are:

1) Load an external JavaScript library, e.g. protovis.js
2) Run some other JavaScript which creates something in the DOM, e.g.
the vis = new pv.Panel().canvas(PVis); .vis.render(); part
3) In GWT access the rendered PVis component.

If that's correct, then by moving the protovis.js to the .gwt.xml
part your ensuring that the library loads before your GWT, but it is
still possible that part (2) is executing after your GWT code, and
hence it is not available to your GWT code when it runs.  You could
wrap that code in it's own file and load through the script tag
(though I'm not sure about ordering in the gwt.xl file).

I'd also suggest you use some debugging tools (Firebug for example in
Firefox) to look at what your code is doing, that should show you the
scoping of pv etc.

(though you might be better off writing a wrapper using JavaScript
Overlay types (http://googlewebtoolkit.blogspot.com/2008/08/getting-to-
really-know-gwt-part-2.html) that would let you merge GWT and the
protovis library in a more natural style, than the approach you're
taking just now)

Good luck,

Drag and Drop, how to activate an action when dragging over a widget?

2009-07-20 Thread Memo Sanchez


Good morning.

I created an special scrollPanel, which scrolls when clicking into the
right or left button. Does anyone knows how can I activate the onClick
behavior of the left and right buttons when I am dragging a widget
over them?.

Thank you for your time.

Re: Add external java project to GWT project in Eclipse

Hi Martin,
You may try using the link source option, as suggested by the thread at
http://groups.google.com/group/google-appengine-java/browse_thread/thread/1908b3bedf954b75/ca0370ae3ae5a394?lnk=raot.
If that doesn't work, you could set the output directory of your
dependencies to be the GWT output folder.

Common parent project - How?

2009-07-20 Thread Wualla


Hi

Scenario:

Core client and server code needs to be shared among several projects
(referred to as child projects)

My try was ro create the core project as a GWT project, and add it to
the build path of the child projects as a dependency project.

Under Jetty, everything works OK except I get this message:

[WARN] Server class 'com.mycompany.core.client.domainObjects.User'
could not be found in the web app, but was found on the system
classpath
[WARN] Adding classpath entry '.../Core/war/WEB-INF/classes/' to the
web app classpath for this session

When deployed - to Tomcat - I get:

...
javax.servlet.ServletException: Error instantiating servlet class
com.mycompany.myProject.server.MyServiceImpl
...
java.lang.NoClassDefFoundError: com/mycompany/core/client/domain/User
...
java.lang.ClassNotFoundException:
com.mycompany.core.client.domainObjects.User
...

What should I do? Help please...

Re: GWT UI design best practices

 I have worked with web for ages, and although I am not that good at

 not sure how to set things up to look good. One approach I am trying a
 bit now is to have panels, and have the elements as anonymous class
 extensions off the fields:

 public class SomePanel extends FlowPanel {

             addStyleName(span-10);
             addKeyUpHandler(...);

 I am also considering now to just write things up in HTML, then
 convert it all to DOM.create, but that seems overly verbose. I really
 hope UiBinder becomes available soon, as that seems to be closer to
 what I would like to have. Anyone got any good advice for how I should
 organize classes and panels?

Problem with Horizontal Panel

2009-07-20 Thread Rahul


Hi,
I am not able to see the Horizontal Panel
this is my code

public void onModuleLoad() {
HorizontalPanel panel = new HorizontalPanel();
Label L1 = new Label();
Label L2 = new Label();

L1.setText(Hello);
L2.setText(Hello 22);
panel.add(L1);
panel.add(L2);
RootPanel root = RootPanel.get();
root.add(panel);
}
}

When i change horizontal Panel to horizontal shift panel its works,
but it does not works with horizontal panel
why is that?

Re: Add external java project to GWT project in Eclipse

2009-07-20 Thread Donald W. Long


I looked at the linked source method and you have to have the linked
source fully qualified.  Thats nice if you always have your source in
the same place.  You could try using the linked variables but then
thats also work.  Do not see this as a real option for projects that
will be worked on by many developers at the same time.

If I am wrong please let me know.

Re: Add external java project to GWT project in Eclipse


Hello Jason,

thanks for your interesting hints. I tried the Google App Engine
first, but to no avail. I tried to convert my project to use the
Google App Engine, but then I got some errors referring to missing XML
files.
The second approach sounds also interesting, but I need a little hint
there. Where exactly do I have to set the output folder to?

Let's say, I have two Projects:

GwtApp
--src
com.company.gwtapp
--GwtApp.java


DataProject
--src
com.company.data
--Employee.java


And I want Employee.java to be available in my Gwt App, what do I have
to do? In Eclipse, Configure build path on DataProject, then
source, then change default output folder? If so, to what value
should I change it to?

Re: What is the best way to enable save/apply button on TextBox edit

2009-07-20 Thread Donald W. Long


You just need to write your code to keep track of the state.  If data
is in the text box and then it goes to delete then its changed and
enable the buttons.

Its all in tracking the state of the contents.

On Jul 20, 2:29 pm, Bakul bakul.ku...@gmail.com wrote:
 I appreciate your quick replies. Suggested solution looks promising.

 However, my confusion is:

 What will happen if user select the content, that is already there by
 mouse double click and press delete.

 As in this case, on load buttons are disabled, now user has selected
 it through mouse and pressed delete button, so onKeyUp length is '0',
 hence it will not enable the buttons even though there is a change in
 value.

 I know thats its a rare case, but I am writing a framework related to
 it for a large scale project.

If I goes and add KeyBoardListener and try to handle it on onKeyDown

Re: JSNI: window vs $wnd

Darth, ...ahh, great thanks.

I got to $wnd to work for code in the cross-site communication
tutorial. I think the problem was that I was using document and $wnd
rather than $doc and $wnd. I haven't completely worked out in my
head why the former wouldn't work but it seems sensible that you would
need to make sure it's all either happening on the host page or all in
the iframe.

Any guess why the tutorial uses window/document rather than $wnd/
$doc ?

Thanks again,

 Right after the first example.

 window = host page
 $wnd = the nested iframe page where your scripts reside

 From the tutorial you cited, I'm not sure why it doesn't work when
 using $wnd. Maybe the nested page can't write to the host page?

Hello Sean,

thank you very much. I've thought of that solution too, but it is not
appropriate for my GWT project. I have to add 4 external projects to
my GWT project, and all of these 4 projects are subject to change
every day. It would be too much work to export them to a jar file
every day. Is there some way to automatically add the external project
sources to the GWT output folder?

Re: JSNI issues

2009-07-20 Thread wsaleem


2) is the pure JS scenario, which I trying to port to GWT using JSNI.
I fail, though, as the very first command
  vis = new $wnd.pv.Panel().canvas(PVis);
fails with the following JavaScript exception
  $wnd.pv has no properties
I will see if the overlay types help. Thanks for the pointer!

 It could still be a similar thing; I'm not 100% clear what you are
 trying to do above, but it looks like your steps are:

 1) Load an external JavaScript library, e.g. protovis.js
 2) Run some other JavaScript which creates something in the DOM, e.g.
 the vis = new pv.Panel().canvas(PVis); .vis.render(); part
 3) In GWT access the rendered PVis component.

 If that's correct, then by moving the protovis.js to the .gwt.xml
 part your ensuring that the library loads before your GWT, but it is
 still possible that part (2) is executing after your GWT code, and
 hence it is not available to your GWT code when it runs.  You could
 wrap that code in it's own file and load through the script tag
 (though I'm not sure about ordering in the gwt.xl file).

 I'd also suggest you use some debugging tools (Firebug for example in
 Firefox) to look at what your code is doing, that should show you the
 scoping of pv etc.

 (though you might be better off writing a wrapper using JavaScript
 Overlay types (http://googlewebtoolkit.blogspot.com/2008/08/getting-to-
 really-know-gwt-part-2.html) that would let you merge GWT and the
 protovis library in a more natural style, than the approach you're
 taking just now)

 Good luck,

 //Adam

   Hi,

   It might be the case that in both cases your GWT code is loaded and
   executing before the browser has loaded your externally referenced
   JavaScript file.  To remove that possiblity, you can place the
   script tag you have in the HTML into your module's .gwt.xml
   definition, i.e.

   module
      inherits name='com.google.gwt.user.User' /
      script type=text/javascript src=protovis.js
   /module

   With this sett up, the GWT boostrap code should ensure the library
   JavaScript is loaded before your GWT code executes.

I am not a JS developer and use it pretty much by example, so it might
be that I am missing something really basic below.

I have come across problems using JSNI in the following 2 scenarios:

1.
I use Google Visualization API successfully in JS as follows:

HTML file
    script type=text/javascript src=http://www.google.com/jsapi;/
script
JS file
    google.load('visualization', '1', {'packages':['piechart']});  //
== future JSNI problems occur here
    var chart = new google.visualization.LineChart
(document.getElementById('GoogleVisChart'));
    // other JS commands to draw the chart
**
and then try to write a wrapper using GWT JSNI as follows:

HTML file
    script type=text/javascript src=http://www.google.com/jsapi;/
script
JAVA file
    class GChart {
      static { _init(); }
      private static native void _init() /*-{ // === ERROR at this
function
        $wnd.google.load('visualization', '1', {'packages':
['piechart']});
      }-*/;

      JavaScriptObject gvis;
      public GChart( String id ) { gvis = _chart( id ); }
      private native JavaScriptObject _chart( String id ) /*-{
        return new $wnd.google.visualization.LineChart
($wnd.document.getElementById( id ) );
      }-*/;
      // methods to draw the chart through native functions
**
The GWT compiler gives the following error for the above code

for details)

Hi Martin,
For the Linked folder location, ensure you have the trailing src
included.

 Now I tried the link source function without Google App Engine. At

 The only problem is: The package declarations produce errors. Eclipse

 What to do?

  Hello Donald,
 
  I already tried the Google App Engine approach, but it didn't work for

  Meanwhile, I tried the output folder approach. I tried to change the
