Announcing Screencast on how to setup Gin for IOC

2012-10-05 Thread gpike
Hi everyone just wanted to let you know I released a screencast on using 
Gin in your GWT application to control the lifecycle of your objects. Gin 
extends the features of Guice for use in your client code. It can be 
beneficial in writing more componentized code, that is easier to test and 
or mock. Check it out and the source code is available on GitHub.

Re: Help in JSNI callback in javascript object

2012-10-02 Thread gpike
If you want the callbacks to call into your Java methods one way to do that 
is to assign those methods to a globally accessible Javascript variable. 
Then you can register those as callbacks to your on_event calls. The 
example I'm showing is static but you may be able to use instance methods. 
Something like (keep in mind I'm writing on the fly so may not be exactly 
right): 

public static void onSipEventStack(JavaScriptObject evt) { ... }
public static native void exportStaticMethod(JavaScriptObject tsip) /*-{
   $wnd.onSipEventStack =
  $entry(@mypackage.MySipClass::onSipEventStack(evt));

tsip.on_event_stack = $wnd.onSipEventStack;

 }-*/;

You could also setup a Javascript overlay object for the tsip object so 
you can make calls to it from you Java code. I hope that helps. 
Thanks,

Re: GWTRuby? How to communicate?

2012-09-25 Thread gpike
I agree with tc. In your rails controllers set your respond_to blocks to 
render json then you can use RequestBuilder to make your rest calls. You 
can then create jsni methods that eval the json and return Javascript 
Overlay object that you can use in your app. During development you may 
want to setup Apache as a reverse proxy so that you can run your GWT code 
in dev mode and call your Rails services running on a separate port 
(because of the cross site scripting limitations they need to be on the 
same domain, which means same port too). Alternatively you probably could 
use JRuby during development and make sure you can still deploy to MRI.

Re: How get iFrame contents with different domains ?

2012-09-25 Thread gpike
Hi,

  You can't directly in GWT it honors cross site scripting you can however 
drop down to Javascript. Write a JSNI method that accesses the containing 
docs parent (your app) by accessing top, then in your code you can access 
the iFrame and then it's document. Something like this:

public static DocumentElement getFrameDocumtent() {
FrameElement top = getTopDocument().getElementById(MyiFrame);
return top.getContentDocument();
}

public static native Document getTopDocument() /*-{
return top.document;
}-*/;

I haven't tested this code but pulled pieces from some of my working code 
to give you an idea.

Hope that helps,

Re: How get iFrame contents with different domains ?

2012-09-25 Thread gpike
After sending this I realized I sent it too early. The code below only 
works after you get both documents under the same domain because of 
cross-site scripting protection in the browser. To bring them both under 
the same domain you can either setup Apache or Nginx as reverse-proxy or 
write a servlet deployed with your GWT server side code that proxies 
requests to the other domain. If you just have a couple of pages to proxy I 
would do the servlet approach. I've done both methods. There are a couple 
of example proxy servlets you could start with and deploy one of them in 
your web.xml.

Re: Logging in GWT

2012-09-23 Thread gpike
I use the built in GWT logging. It works for us, and we can use the remote 
logging so that info can be included in the server log in production. Your 
classes use java logging classes. Add the import and configure the loggers 
you want in the module file something similar to:

inherits name=com.google.gwt.logging.Logging /

set-property name=gwt.logging.firebugHandler value=ENABLED /
set-property name=gwt.logging.enabled value=TRUE/ 
set-property name=gwt.logging.logLevel value=FINE/
set-property name=gwt.logging.consoleHandler value=ENABLED /
set-property name=gwt.logging.developmentModeHandler value=ENABLED /
set-property name=gwt.logging.popupHandler value=DISABLED /
set-property name=gwt.logging.systemHandler value=ENABLED /
set-property name=gwt.logging.simpleRemoteHandler value=ENABLED /

If you use remote remote logging make sure to add the servlet to your 
web.xml.

Re: preview in case of iframe

2012-07-02 Thread gpike
  The document inside you iFrame is a completely separate document and can 
be from a different domain as well so won't get any events just like you 
don't get events from other browser tabs. However you could communicate 
across the boundary by defining your own api's. What I mean is you can add 
Javascript methods to the containing document and call them from the child 
using top.insert method name. 

  What I've done in the past is create 2 entry points (and 
modules), essentially two GWT apps,  one for the parent window and the 
other for the child window. Using JSNI expose a well know method name on 
the parent that can be called. It can be a pain but we had an app that 
could be hosted in another app using a iFrame and could have hot key 
support for both passing key events to the parent. By the way this only 
works when both apps are from the same domain.

Good Luck,
 
Gordon Pike

 I have been struggling with this for the whole day and can't crack the

 I know how things work when you call 
 Event.addNativePreviewHandler(handler) to trigger event preview. The 
 preview is meant to be a global concept so that anything events 
 happening else where would get previewed. However, if an iframe is 
 added into the picture, the previewer is apparently not so global. 
 things happening inside the iframe does not trigger DOM.preview(evt), 
 and therefore does not get previewed. 

 I suppose this makes sense, that the iframe has an independent DOM 
 structure from the parent. Does any one know of a way to bridge the 
 two so that the two parts together still behaves truly in a GLOBAL 
 way?

Re: pass variable from JavaScript to GWT

2011-05-12 Thread gpike

If I understand your question correctly, you want to use a value that has 
been populated by JavaScript then it should be as simple as:


public final native String getValue() /*-{
return $wnd.a;
}-*/;

but if you are wanting to pass the value to the JavaScript then it would be 
like:

public static final native void setValue(String myValue) /*-{
$wnd.a = myValue;
}-*/;

Is that what you are asking for?

Re: GWT RPC + Spring (saga)

2009-07-15 Thread gpike

Hi,

  You can use the Spring listener in the web.xml:

listener
listener-class
org.springframework.web.context.ContextLoaderListener
/listener-class
/listener

   Then in any of your Servlets you can use the context:

   WebApplicationContextUtils.getWebApplicationContext
(getServletContext()).getBean(someBean);

Re: GWT and Hibernate XML files vs Annotations

2009-05-20 Thread gpike

Rafael,

 You could use annotations to describe the mappings but if not use the
following. Since you are using Spring you can use their Hibernate
support to look for mapping files in a particular directory. This way
you don't have to call them out in the hibernate file. Lookup
org.springframework.orm.hibernate3.LocalSessionFactoryBean. Here is an
example:

bean id=sessionFactory

class=org.springframework.orm.hibernate3.LocalSessionFactoryBean
property name=dataSource
ref local=dataSource /
/property
property name=hibernateProperties
props
prop key=hibernate.cache.provider_class

org.hibernate.cache.HashtableCacheProvider
/prop
prop key=hibernate.dialect
org.hibernate.dialect.Oracle10gDialect
/prop
prop key=hibernate.show_sqlfalse/prop
prop key=hibernate.format_sqlfalse/prop
/props
/property
property name=mappingDirectoryLocations
list
value

classpath*:/org/myexample/server/dao/hibernate
/value
/list
/property
/bean

The mappingDirectoryLocations property tells spring to look for
hbm.xml files in the org.myexample.server.dao.hibernate package. Then
you need a *.hbm.xml for each table and the relationships are defined
in those files. You also need a datasource described in your
application context.

Hope this helps.

 Hello everyone!

    I have the following problem and was hoping you guys could help me
 out. I have the need to implement a relation inheritance (table per
 subclass) so i searched the hibernate documentation.
    The thing is that i am using a project structure which i took from
 a tutorial i found, and i have the following configuration files:

 applicationContext.xml (Spring stuff i suppose)

 hibernate.cfg.xml (mappings)
 database.hbm.xml (hibernate query definitions)

 My question is where should the code to define complex relations
 should go, hibernate.cfg.xml or database.hbm.xml?

 Is it possible to take care of everything with annotations
 (eliminating the need to change xml files)?

 Thanks in advance y'all!

 PD: Thank you Eggsy for your tutorial on GWT, Hibernate ans Spring
 combined! very enlightning :)

Re: Failed to import and run gwtrpc-spring example with Google plugin

2009-05-19 Thread gpike

Sorry I missed this thread before. Yes it was compiled for 1.6. I
should have targeted 1.5 and will in the next release since there is
no dependency on 1.6. It probably would be safe for 1.4 but I use
Annotations so haven't needed it.

Thanks,

 Hey again Hez,

 I think you're right -- it turns out that gwtrpc-spring-1.0.jar (if
 you downloaded it from the gwtrpc-spring project [0]), is compiled for
 Java 1.6.

 [0]http://code.google.com/p/gwtrpc-spring/

 Thankfully, it's open-source, so you can probably grab their code and
 compile it for 1.5, or possibly poke the gwtrpc-spring developers and
 get them to make a 1.5-compatible build.

 If you take out your dependence on gwtrpc-spring and remove that jar
 from your classpath, does it prevent that error?

 Thanks!

Re: Bar code scanner

2009-05-06 Thread gpike

Hi Hez,

  It's been my experience that most if not all scanners come with
either a hardware or software keyboard wedge. If it doesn't you may
want to look at the problem differently. Provide a software keyboard
wedge, what this will do is receive the input from RS-232 or USB and
emulate keyboard input for the platforms you want to support. Then
your GWT app doesn't have to worry about it. The one thing you may
need to account for is sometimes the input is wrapped in a beginning
and end character i.e. 1234 becomes *1234*.

Gordon

 Hi
 My customer is asking if my GWT application is able to accept input from the
 bar code scanner.

 I have not done anything with bar code scanner before this, but this is what
 I got from Google:
 A bar code scanner is typically comes with a keyboard wedge output or
 a RS232 output.

 I think there is no problem if using bar code scanner with keyboard wedge
 output,
 the scanner will input the string into the text field as if the user is
 typing it from the keyboard.

 The problem is when the customer is using bar code RS232 output, how do I
 populate the string into the text field?

Announce: Simple GWT and Spring integration

2009-05-05 Thread gpike

If your looking for a clean simple way to allow your RPC services to
hosted in Spring or have existing Spring services that you would like
to access as RPC services then take a look at 
http://code.google.com/p/gwtrpc-spring/.

GwtRpc-Spring provides a RemoteServiceDispatcher that takes rpc
requests from the client and looks for the service in your Spring
Context. Your service only needs to implement the particular remote
service interface and be defined in your application context.

The project can be found at:  http://gwtrpc-spring.googlecode.com

 An example project can be found at: 
http://gwtrpc-spring.googlecode.com/files/GwtRpcSpringExample.zip

 And a tutorial at: 
http://devbright.com/2009/05/gwt-and-spring-introducing-gwtrpc-spring-project/

Enjoy,

Re: GWT and Spring annotation

Can you provide more information? Are you including one project in the
other by including a jar etc..? What annotations are you using?
(@Component, @Service etc..)

 Hi,

 I have a problem with GWT and Spring integration. On Eclipse, I have 2
 projects : GWT project (presentation) and Spring project (service). I
 am calling the spring context from a GWT remote service
 (WebApplicationContext).

 If I declare spring beans in a spring XML, I see them no problem.
 but if I try to declare beans with annotations I can't see them. If I
 declare these beans in the presentation project, then I can see them !

 In conclusion, I have to put annotated beans in the another project
 than GWT one I can't see them...

 Do you have an idea of the problem ?
