Validation-api-1.0.0, Doesn't work

[MaximeMularz]

Hi,

I tried to use Validation-api-1.0.0 with GWT 2.3 but it didn't
work !!!

My Code :
Line 32. : Validator validator =
Validation.buildDefaultValidatorFactory().getValidator();

The Error :
09:18:57.323 [ERROR] [validation] Line 32 The method
buildDefaultValidatorFactory() is undefined for the type Validation


Thanks for your help

Maxime

Hi Maxime,

I also am trying to test the validation api.

The fact that no work for you is normal, generic classes are calling facto standard.
You should call the classes implemented by google.
Before you continue writing, you could say that you imported libraries anddependencies on other projects are you working?

A greeting.

Hi Adolfo,

I added in web-inf/lib "Validation-api-1.0.0.GA" and "Validation-
api-1.0.0.GA-sources", What are the classes implemented by google ?

Hi,

First, I recommend that you download the repository gwt development [

http://google-web-toolkit.googlecode.com/svn/trunk/

]. 

The project amountsto eclipse gwt-user and the project sample / validation.

Once you do that look in src/com.google.validation (here there is the GWT class validation) and src/org.hibernate.validation.

Those are the two main projects of validation for google. In addition to the standardbase classes Bean Validation JSR-303 (coming in the package javax.validation).

Once you've done this, you must import your project in the gwt-user and use in your***. gwt.xml one similar to that comes in the sample project.

Now I'm at that point, when you add the gwt-user project to my main project,something is wrong.

A possible hand solicion would compile the gwt-user project and use the classes ofthe packages described above (these classes do not appear in the distribution of theSDK provided by Google). This step I am not able to do so because as I can compilewith ant. If you are able to do it yourself, then you explain step by step how to run thevalidation api.

Greetings!.

Hi,

I compiled the sources but when I'm using Validator validator =
Validation.buildDefaultValidatorFactory().getValidator(),

these are the errors :

Try it with: 

Validator validator = GWT.create(SampleValidator.class);

Other thing, send us the modules that you are inhertir in your project.

If you use your form, you must specify in your xxx.gwt.xml the change of the class (remember, you must use the gwt class and not the standar class), like this:

<generate-with class="com.google.gwt.validation.rebind.ValidatorGenerator">

<when-type-assignable class="javax.validation.Validator" />

</generate-with>

Please, send me the jar that you are compiled at adolfo...@gmail.com ?? If I have the gwt-user.jar that includes all the packages of validation y can do it an example and I can solve your problems.

Thank you very much.

Another thing I forgot, you could specify the steps you have done to compile the gwt-user project?

Thanks in advance.

Hi Maxime,
I answered for you in the mail from which you sent me the link.

While I wait your answer I am working to see if I can fix it.

Thank you very much for everything.

Hi,

1/ I did the tuto : http://code.google.com/webtoolkit/makinggwtbetter.html#workingoncode.
2/ I visited this page "http://subversion.apache.org/packages.html"
3/ I downloaded and Installed : Win32Svn (32-bit client, server and
bindings, MSI and ZIPs; maintained by David Darj)
4/ I added SVN.exe to the PATH
5/ and the command ant !!!

Hi, 

[I feel like a complete idiot right now. XD. There is a tutorial on google!]

Ok. I'm putting to work to try to compile everything on my own in the meantime, if youmanage what you put in the mail to compile all the SDK and get it, accelerate the whole process and so I can create the complete sample validation .

We are in touch, thank you very much for everything.

You've read the email you send to another address? Is there a problem that prevents theapplication run.
I need all the sdk result of the compilation not only gwt-user.

I copied the email you send:

Listen, now there is another problem, when I substitute the "gwt-user"original, foryours in the GWT SDK and run the project. There's something I do not like eclipse.

[I have no choice but to do this because if I include your lib in the classpath when the module of my project runs collides thw sdk of google and your library compiled]

I enclose a picture.

Would you know how to fix? I believe that through a compilation entire google sdk(which if you look very similar to what you've done just that by running the ant.xmlgeneral) would end the problems.

[Adolfo Panizo Touzon]

Hi Maxim!!!

It works!!!

I have made a very simple example based on Google (because if you have a problemthat I do not solve, sure there are people that if you could lend a hand.)
The steps you follow are the following:

-Add the project (which I attached) to your workspace.
-Select your gwt sdk 0.0.0.0
-Add the libraries to your classpath you in the picture attached.
-Run it.

If you have any questions or comment on it is a problem here that I miss you a hand with any thing.

Greetings!

Now I work as an example to finally understand itself completely.

Adolfo Panizo.

You can save the errors strings in an arrayList<String> and transpor by rpc to the client side.

I don´t understand. ¿What´s the problem?

Maybe you can declarate HashMap in the client side and can´t transport by rpc.

I´m not sure, but, what´s the problem?

Try adding gwt-servlet-deps.jar and gwt-servlet,jar to your build path.

These Classes are not in the api :

javax.validation.ConstraintViolationException_CustomFieldSerializer

org.hibernate.validator.engine.PathImpl_CustomFieldSerializer

How can i add them ?

I have hibernate-validator-4.1.0.Final.jar and validation-api.1.0.0.GA.jar in my lib

I downloaded them from the Hibernate Validation project at

http://www.hibernate.org/subprojects/validator.html

Hibernate Validator 4.x is the reference implementation for JSR 303 - Bean Validation of which Red Hat is the specification lead.

You will need to do something like this.

public class ExposeImpl implements IsSerializable {
  
  @SuppressWarnings("unused")
  private ConstraintViolationImpl<?> constraintViolationImpl;
  
  @SuppressWarnings("unused")
  private PathImpl pathIpml;
  
  @SuppressWarnings("unused")
  private HashSet<?> hashSet;
}

And then Create a dummy method like the following in your RemoteService

 ExposeImpl dummy();
 

I am working on a simpler solution.

more details ?

Maybe it can help you

http://stackoverflow.com/questions/2116583/gwt-java-security-accesscontrolexception-access-denied-for-serializer-in-ubunt

revise, maybe that this exception can not serialize. 

Also revise the configuration of the server.

engine ?"

Thanks
