GWT RPC was a must to have 10 years ago but nowadays all modern projects 
use REST/JSON API (it makes your APIs really easy to mock/test with all 
modern REST/JSON frameworks like Spring / Resteasy / Jersey vs GWT RPC APIs 
that are complex to test)

You can "easily" migrate your GWT RPC project to GWT RestyGWT (and use 
Spring boot / Resteasy on server side with a shared JAX-RS interfaces with 
your client)

I have a demo project using this approach:

Re: GWT with Spring Boot

Hi, 

How could you not be sure why I'd want to use one of the fundamental 
principles of GWT, which is GWT RPC? Either I'm missing something, or you 
are! 

What is "Gwt web builder"? I've never heard of it and Googling it finds 
zero results.

Re: GWT with Spring Boot

Hi 
i am not sure why you need RPC when using springboot or any webservice 

you can try Gwt web builder 
which will call directly from your gwt client to springboot .. without RPc

Hi, 

I'm trying to convert a GWT project over to use Spring Boot. I'm not able 
to find an example anywhere that uses GWT RPC with Spring Boot. 

Is this possible? Can anyone point me at an example please?

GWT into Spring Boot with remember-me is not working

[Josep Llort Tella]

Hi

I have an application based in Spring Boot and the latest GWT 2.8.2. In the 
application I have some protected resources one with GWT and others with 
standard Servlets and JSP pages. 
Now I have included remember-me feature, the remember-me feature is working 
with all the protected resources except with GWT section what fails

My GWT Servlets extends RemoteServiceServlet

It is raising this error:
org.springframework.security.web.authentication.rememberme.CookieTheftException:
 
Invalid remember-me token (Series/token) mismatch. Implies previous cookie 
theft attack.
at 
org.springframework.security.web.authentication.rememberme.PersistentTokenBasedRememberMeServices.processAutoLoginCookie(PersistentTokenBasedRememberMeServices.java:120)

I have debug the internal spring security class 
PersistentTokenBasedRememberMeServices and the error it is raised because 
the initial tokenValue for some reason is changed in the middle:

@Override
protected UserDetails processAutoLoginCookie(String[] cookieTokens,
HttpServletRequest request, HttpServletResponse response) {

if (cookieTokens.length != 2) {
throw new InvalidCookieException("Cookie token did not contain 
" + 2
+ " tokens, but contained '" + 
Arrays.asList(cookieTokens) + "'");
}

final String presentedSeries = cookieTokens[0];
final String presentedToken = cookieTokens[1];

PersistentRememberMeToken token = tokenRepository
.getTokenForSeries(presentedSeries);

if (token == null) {
// No series match, so we can't authenticate using this cookie
throw new RememberMeAuthenticationException(
"No persistent token found for series id: " + 
presentedSeries);
}

// We have a match for this user/series combination
if (!presentedToken.equals(token.getTokenValue())) {
// Token doesn't match series value. Delete all logins for this 
user and throw
// an exception to warn them.
tokenRepository.removeUserTokens(token.getUsername());

throw new CookieTheftException(
messages.getMessage(

"PersistentTokenBasedRememberMeServices.cookieStolen",
"Invalid remember-me token (Series/token) 
mismatch. Implies previous cookie theft attack."));
}

Yes. If you want to use default implementaion of the "filter chain", you 
have to use namespaces () for configuration or you may use JavaConfig 
aproach.

When you removed spring security filter-chain stuff, ability to inject 
SecurityContext to HttpRequest has been removed too (that's what one of the 
security filters does). 
So all requests handled on behalf of Anonymous user (even after 
authentication in RPC service).

I suggest to use separated page for "plain" login HTML form without gwt 
rpc. Thus, you can use default form login support from spring security.
Then, you should configure access rules for http requests (by using  
namespace or JavaConfig... there is a lot of info and samples):

1. Allow login page for all.
2. And restrict all other URLs for authenticated only.

And, there is some example with custom implementation of the 
AuthenticationProvider [1] if you do not want to implement separated login 
page.

Re: GWT and spring security integration,DelegatingFilterProxy has a dead loop

[Alex Luya]

Does this mean if add  added blow to web.xml:



springSecurityFilterChain

org.springframework.web.filter.DelegatingFilterProxy


springSecurityFilterChain
/dp_web/service/*



I must use  to configure something in applicationContext.xml?

In my case,I removed above stuff from web.xml,added 

@Secured({"ROLE_USER"})

to class ServiceBase and let all other service inherit from it,and added 
this:

 

to applicationContext.xml,and remove all other spring security related from 
it,rerun my web app,all inherited service invoking
give 500 error,so security mechanism do works, but obviously,following code 
is not enough:

User user = new User(login, password, true, true, true, true, new 
ArrayList());
Authentication auth = new UsernamePasswordAuthenticationToken(user, password,
new ArrayList());
try {
auth = this.authenticationProvider.authenticate(auth);
} catch (BadCredentialsException e) {
throw new ClientSideBadCredentialsException(e.getMessage(), e);
}
SecurityContext sc = new SecurityContextImpl();
sc.setAuthentication(auth);
SecurityContextHolder.setContext(sc);


So question is what else I should do except:

1,add @Secured({"ROLE_USER"}) to parent service
2,add  to 
applictionContext.xml

GWT and spring security integration,DelegatingFilterProxy has a dead loop

[Alex Luya]

There is a pure GWT solution here:GWT Spring Security Integration (PURE 
GWT, NO JSP)

1,Do not use http element at all (http tag from config namespace)

2,Define your AuthenticationRpcService

3,Add AuthenticationRpcService.authenticate(user,password) method

4,Inject into AuthenticationServiceImpl AuthenticationProvider bean from 
security-context.xml

5,Implement AuthenticationRpcService.authenticate(user,password) as :

User user = new User(login, password, true, true, true, true, new 
ArrayList());
Authentication auth = new UsernamePasswordAuthenticationToken(user, password,
new ArrayList());
try {
auth = this.authenticationProvider.authenticate(auth);
} catch (BadCredentialsException e) {
throw new ClientSideBadCredentialsException(e.getMessage(), e);
}
SecurityContext sc = new SecurityContextImpl();
sc.setAuthentication(auth);
SecurityContextHolder.setContext(sc);

6,Ensure that spring security filter chain is executed during processing of 
each your GWT RPC call (to be sure that SecurityContext populated into 
SecurityContextHolder).

For this sixth step, added blow to web.xml:



springSecurityFilterChain

org.springframework.web.filter.DelegatingFilterProxy


springSecurityFilterChain
/dp_web/service/*


and blow to applicationContext.xml:



Then call authentication service,got blow error:

As you can see there is a *dead loop* that causes StackOverflowError,and I 
am not good at spring,after two hours googling,can't figure out a way to 
solve this problem,so can anybody help me?Thanks.

GWT and Spring Boot with gwt-maven-plugin

[apanizo]

Hi all,

I am trying to integrate GWT in a given spring boot project (Kurento Room 
). Everything looks good until I 
launch SpringBoot. The error that I see is:

*Caused by: java.lang.IncompatibleClassChangeError: Implementing class*


*over some server classes*. After googling a bit, normally that is because 
I have two versions of the same library/classes in my Tomcat. So far so 
good.

The thing is if I comment in my *pom.xml *everything related gwt 
(*gwt-maven-plugin, 
gwt's dependencies...*) *the problem disappears*.  The gwt classes are 
minimal, just an empty EntryPoint with an:
 

*Window.alert("Hello World"); *

 
So, I imagine is something related with *gwt-maven-plugin*. What am I 
missing? Can you give me some ideas?

Some notes:

I have searched inside the final jar and using "find" command only shows 
one class.
I have run the duplicate-maven-plugin 
 and there 
is no strange things related with the classes.

I am running in GWT 2.8-SNAPSHOT with 2.7.0 maven plugin. Java 1.8 

I have attached *pom.xml* and *exception stack strace( *
https://docs.google.com/document/d/1LuJ5oJ4rwbMl9Wbx881XyN5GwI2mCdhKk6L_RdIIoCM/edit?usp=sharing
 
*)* just in case I am missing something. 


Thanks in advance,

Adolfo.

[gwt-contrib] Problem deploying GWT+Maven+Spring War on tomcat 6

[efsiken]

Hello,

I developed a GWT+Spring+Maven application on eclipse helios and all works 
well on eclipse. I clean, compile and install the application without any 
problem. But when deploy the generated war file on tomcat 6, deployment is 
successful, but the application doesn't start.

Here is the error I get on the tomcat application manager:

 ECHEC - L'application pour le chemin de contexte /test1 n'a pas pu être 
démarrée

and here is the tomcat6-stderr.log file:

Re: Lessons learned moving from GWT to Spring MVC

[Ed Bras]

To be honest: I don't even know another  framework like GWT that match my
desired setup ... Do they even exists? So it's like comparing peers and
bananas...

My setup (which I love).. A separate backend (Spring) and frontend (GWT),
that are deployed separately in respectively Tomcat and Apache httpd.
A few nice things:
1) Separate development of backend and front end.
2) Separate teams for backend and frontend (RPC communication through
contract interfaces). Overcomes unncessary dependencies that slows down
development... As such: fast development, changes and bug solving...
3) Fast startup of dev mode due to noserver mode (no need for gwt
yetty/tomcat).
4) Full control/inside of communication between backend and front-end, that
leads to easy performance optimization.
etc...

Which frameworks can offer this?
Note: before I also had both frontend and backend in one war, which is ok
for smaller projects, or if it's required by the client environment, but
the separation of frontend and backend works very nice...

Lessons learned moving from GWT to Spring MVC

[Ed]

Just wanted to share the following webinar:
Lessons learned moving from GWT to Spring MVC
I was just listening to it (it's live now)... and really didn't like it...

The speaker wasn't talking very nice about GWT, not very objective...  all 
the little negatives things where made BIG...
Or maybe they had very bad developers as they talked about slow 
development, hosted mode startup times with over a minute :( etc.. 
etc...
Or maybe they were just using gwt 1.1 ;)

Strangge not my experience at all...

How can one compare something what  lives almost entirely in 
presentation-layer and has none strong dependencies on server-side (GWT) 
with framework which is focused on server-side without any real widget 
library?

Every SpringMVC app I developed used jQuery to add better experience to 
users.

Re: NullPoniter when calling the DAO object (@Autowired) - GWT and Spring problem integration

Following the linked wiki page you should have

servlet-mapping
servlet-namespringGwtRemoteServiceServlet/servlet-name
url-pattern/springGwtServices/*/url-pattern
/servlet-mapping


and

@RemoteServiceRelativePath(springGwtServices/spring bean name)

So in your case probably: 
@RemoteServiceRelativePath(springGwtServices/GestionUserService)

You don't need to map your GestionUserService at all in web.xml, as its 
managed by Spring and not your servlet container. It doesn't even have to 
be a servlet anymore. Its just a Spring bean.

Re: NullPoniter when calling the DAO object (@Autowired) - GWT and Spring problem integration

[Mathieu Lorber]

Jens, are you sure of what you're saying ? The GWT services have to be 
servlets AFAIK, and are actually managed by the servlet container in the 
given wiki page.

BTW, I'd *strongly* recommend to remove the spring4gwt dependency and 
understand what it does. That is to say :

@SuppressWarnings(serial)
public class SpringRemoteServiceServlet extends RemoteServiceServlet {
@Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
ApplicationContext context = 
WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());
AutowireCapableBeanFactory factory = 
context.getAutowireCapableBeanFactory();
factory.autowireBean(this);
}
}

Your services have to extend SpringRemoteServiceServlet instead of 
RemoteServiceServlet.

That's it. Less than 10 lines of code do not deserve a dependency =)

 servlets AFAIK, and are actually managed by the servlet container in the 
 given wiki page.


Re-read point 2.) + 3.) of the wiki page. If the wiki page isn't wrong you 
only have to declare a name for your GWT-RPC service implementation 
(@Service). In the example GreetingServiceImpl does not extend anything. It 
just implements the service interface. So its not a servlet.

The only servlet you need in web.xml is the spring integration servlet.

You're right, i wanted to go too fast... Actually spring4gwt does not use 
the method i talked about. And as you have to write spring beans, it's 
simpler to add services.

But i continue to think it does not deserve a jar dependency =/

I'd like to see a native (aka gwt sdk) mechanism to do this. Does the 
dependency on servlets has a sense ?

Hi, im writting the code for a console using GWT and Spring integration. I

I'm at the point that the RPC call is returning null and i can't seem to 
see why. As english is not my native language and i'm pretty new to this, 
I'm just going to put my code here to see if someone can help me with it.

Re: NullPoniter when calling the DAO object (@Autowired) - GWT and Spring problem integration

[Jens]

Its not a GWT issue. You have either spring4gwt or spring itself 
misconfigured as it seems like that utilDb is null and thus @Autowired 
simply does not work.

You should start 
re-reading http://code.google.com/p/spring4gwt/wiki/SimpleRPCExample and 
make sure that your config is correct. I would guess your servlet mapping 
is wrong.

GWT with Spring Webflow

[Inko37]

Hey,

is it possible to use GWT and Spring Webflow? I don't know if there are any 
problems with the asynchronous calls. If it will work, is there any ready 
solution for it? Or is there any other solution to manage the webflow with 
GWT?

best regards,
Inko

 ready solution for it? Or is there any other solution to manage the webflow
 with GWT?

 best regards,
 Inko

GWT 2.4 Spring Integration Using RequestFactory

[POODevelopper]

I'm currently Working on a GWT 2.4 / Spring 3 application and want to
use the RequestFactory API to communicate with Spring services.

I searched and find that to integrate GWT integrate with Spring
beginning from 2.4 you just need to create a custom ServiceLocator
that expose your Spring beans.

public class SpringServiceLocator implements ServiceLocator {

public Object getInstance(Class? clazz) {
ApplicationContext context =
WebApplicationContextUtils.getWebApplicationContext(
RequestFactoryServlet.getThreadLocalServletContext());
return context.getBean(clazz);
}

}

And you need to configure you RequestFactoryServlet as mentioned on
the Google documentation.

I followed theses steps but my when GWT client make a Request to the
Back-end i receive this Exception :

Re: GWT 2.4 Spring Integration Using RequestFactory

[Kevin Jordan]

From that, it sounds like you may have a 2.3.0 version of
RequestFactory on there too if you are indeed trying to use 2.4.0.
The line in question in the top of the stack trace makes no sense for
the 2.4.0 source, but in the 2.3.0 source it does:
Method contextMethod = service.resolveRequestContextMethod(
operation[0], operation[1]);

which in 2.4.0 became:
Method contextMethod = service.resolveRequestContextMethod(operation);

Re: GWT 2.4 Spring Integration Using RequestFactory

You are right, It was because on the build Lib Folder there was GWT
2.3 and 2.4 libraries, I just removed the 2.3 and everything worked.

Re: gwt 2.3 + spring 2 + maven 2

[Mike Chai]

Thanks for the responses. To clarify, I want to use GWT to build an
interface for an existing Java backend that is using Spring.
Integration using the STS isn't needed but I'll probably do it
anyways. Is there a way to do this without using hackish methods?

  Nop. It's works in dev mode inside eclipse. I don't use mvn jetty:run so

 Bienvenido a la comunidad. Yo te puedo recomendar que veas el siguiente

Re: GWT and Spring

[Jeff Larsen]

Si estas interesante en usando RequestFactory, es facil usar Spring con 
RequestFactory en 2.4-RC.

Hacer un class se llama SpringServiceLocator

public class SpringServiceLocator implements ServiceLocator {

public Object getInstance(Class? arg0) {
ApplicationContext ctx = WebApplicationContextUtils

.getWebApplicationContext(RequestFactoryServlet.getThreadLocalServletContext());
return ctx.getBean(arg0);
}
}

y usarlos en totas sus RequestContext annotations

@Service(value=MyService.class, locator=SpringServiceLocator.class)
public interface MyRequestContext extends RequestContext{
 
}

Re: GWT and Spring

[Juan Pablo Gardella]

Thanks Jeff!!

2011/8/2 Jeff Larsen larse...@gmail.com

 Si estas interesante en usando RequestFactory, es facil usar Spring con
 RequestFactory en 2.4-RC.

 Hacer un class se llama SpringServiceLocator

 public class SpringServiceLocator implements ServiceLocator {

 public Object getInstance(Class? arg0) {
 ApplicationContext ctx = WebApplicationContextUtils

 .getWebApplicationContext(RequestFactoryServlet.getThreadLocalServletContext());
 return ctx.getBean(arg0);
 }
 }

 y usarlos en totas sus RequestContext annotations

 @Service(value=MyService.class, locator=SpringServiceLocator.class)
 public interface MyRequestContext extends RequestContext{
  
 }

Hola José

Bienvenido a la comunidad. Yo te puedo recomendar que veas el siguiente
prototipo:

https://bitbucket.org/gardellajuanpablo/gwt-sample/wiki/Home

Si bien es un poco avanzado porque tiene varios frameworks, te puede servir
de guía.

GWT and Spring

[João Peixoto]

Hi everyone
First post, so lets not blow it
I did post this in the Spring forums as well.

I've been searching quite a lot for ways to integrate GWT with Spring,
but so far I haven't found any working method.
I think that the problem is that some detail step is missing, but
nevertheless here goes what I have and hopefully someone can help me.

The APP I'm trying to create right now is a Spring enabled greeting
service. What I've done:

com.demo.client.DemoService
com.demo.client.DemoServiceAsync
com.demo.server.DemoServiceImpl

The classes themselves are pretty straight forward.

web.xml added the following:

Code:
servlet
servlet-nameDemoSpring/servlet-name

servlet-classorg.springframework.web.servlet.DispatcherServlet/
servlet-class
load-on-startup1/load-on-startup
/servlet
servlet-mapping
servlet-nameDemoSpring/servlet-name
url-pattern*.rpc/url-pattern
/servlet-mapping
DemoSpring-servlet.xml has the following:

Code:
?xml version=1.0 encoding=UTF-8?
!DOCTYPE beans PUBLIC -//SPRING//DTD BEAN//EN
 http://www.springframework.org/dtd/spring-beans.dtd;
beans
bean id=demoService class=com.demo.server.DemoServiceImpl /
bean id=urlMapping
class=org.gwtwidgets.server.spring.GWTHandler
property name=mapping
map
entry key=/demoService.rpc 
value-ref=demoService /
/map
/property
/bean
/beans
The way I instantiate the service on the client is:

Code:
private final DemoServiceAsync demoService =
GWT.create(DemoService.class);

The problem I'm currently getting is Class Not Found, regarding
GWTHandler in the urlMapping bean.

I understand that URL requests have to be redirected to the Spring
dispatcher, however I'm having a hard time to understand how a
@Service Spring stereotype will relate to a GWT
@RemoteServiceRelativePath and most of all, how to achieve it..

Any tips would be much appreciated.
Best regards

Re: GWT and Spring

Welcome to GWT. You can try read this first:

1) Best Practices!!! gwt

http://dl.google.com/io/2009/pres/Th_0200_GoogleWebToolkitArchitecture-BestPracticesForArchitectingYourGWTApp.pdf

2) gwt-dispatch + spring
http://pgt.de/2009/09/16/use-spring-with-gwt-dispatch/
http://pgt.de/2009/12/09/sample-gwt-dispath-project/

gwt-dispatch implement a best practice to communicate to server via
GWT-RPC.

Isn't there a step-by-step tutorial at least on GWT + Spring Roo ?!  ...
I've searched on Google but can'T find any resource..even only Spring Roo
will suit...Do you have any suggestion? And one more question, do I have to
start with Spring MVC first? Or are Spring Roo and Spring MVC different
subjects ... and that would be better to start directly with Roo maybe?

Re: GWT + MVP + Spring + Hibernate

[Jan Mostert]

ROO is just a console that generates a scaffold for you containing
Spring-MVC code with a JPA (Hibernate) and then you can slap any UI on top
of it, like GWT using the gwt setup command

This page will take you through it step by step:
http://www.springsource.org/roo/start

Once you've done the tutorial, you'll have a scaffold in place on top of
which you can work or which you can modify to your liking.

GWT 2.0 spring hibernate gilead

[Twentyseven]

Hello,

I'm using GWT 2.0, Spring, Hibernate and Gilead for some time now.
Gilead allow me to use the DTO pattern and give me the availability to
update my  DTO's directly.
But my problem is that I have a big  apps and that the merge and clone
are very expensive in cpu and in time.

For now with  GWT 2.0 could I use directly the entity  bean  from
Hibernate (the lazyinitializationexception is not a preoblem for me) ?
I know that Hibernate has his own List implementation could I have
some problems with that ?

Thank's by advance,

you could play with Spring Roo.

Re: GWT-Platform spring integration

[PhilBeaudoin]

Hi Travis,

The feature has been contributed only recently and has not even
compiled in the default jar. Some people have successfully compiled
and used the feature and are working on a sample and it will make it
in the soon to be released 0.5. You can star and follow this issue to
be notified of progress:
http://code.google.com/p/gwt-platform/issues/detail?id=44

Also you will get more answers if you post directly on the gwtp forum:
http://groups.google.com/group/gwt-platform

Cheers,

   Philippe

   Hello Stefan,

   Thanks for the question.

   First let me say that I am a fan of the work that is being done by the
   Roo and GWT teams.  Our goal in releasing additional generative
   tooling forSpringhas always been to give developers additional
  optionsand capabilities that largely complement the freeoptions
   available from SpringSource.

   We have a page that highlights some of the key differences in approach
   between Roo 
   andMyEclipseforSpringhere:http://www.myeclipseide.com/me4s/faqs/faqs_tool_comparison.php

   Specific to GWT, the most important difference for developers to
   consider is the GWT version.  ME4S supports GWT 2.0.x which is the
   current GA version and is based on the best practices presentation
   from Ray Ryan at Google I/O 2009. You can find that presentation 
   here:http://www.youtube.com/watch?v=PDuhR18-EdM

   The Roo integration for GWT is targeted at GWT 2.1 which looks to be a
   great set of additions to GWT, however it is still a work in progress.
   Most of the low level variances in the code that is generated reflect
   the difference in GWT version supported.

   Another difference is that ME4S generates code that does not use
   separate aspect files or design time annotations .  Our goal is to
   generate reusable software components from your existing technology
   assets like RDBMS tables, WSDL Documents, POJO's or Entities as
   quickly as possible giving youoptionsas to which project, source
   folder, and package you would like the generated code to go into.

   You can review videos of the GWT and other scaffoldingoptionsfrom
   ME4S in action here:http://www.youtube.com/user/myeclipseforspring

   Finally, we have an option to let you generate JUST the GWT front end
   and Service stub without requiring the use of any specific back end
   implementation includingSpring.

   ME4S can start from your existing Java code, WSDL, or RDBMS definition
   and generate reusable GWT front end components that are tied to your
   data model and which follow a strong MVP / Command pattern.  These
   components can be mixed and matched together to buildmorecomplicated
   downstream applications that go beyond CRUD.  The Remote Services are
   stubbed out to allow you to integrate with the server side technology
   of your choice, or you can accept the defaults and let ME4S build out
   a layered CRUD backend that includes JPA Entities, DAO’s, and Services
   all wired up usingSpring.

   I hope this helps, but let me know if you would like to havemore
   detail.

Re: Integration of GWT in Spring

[Sebastian Rothbucher]

Hi,

I guess it is a little more difficult than that as you have to
integrate two paradigms here: one is request-response (classic
webapp style of spring web mvc), the other is requesting on demand by
google web toolkit. Possibly the easiest way would be rendering a gwt
carrier page via spring - or embedding GWT via an invisible IFrame; I
don't think it is that easy to just submit the contents of a GWT app
along with other classic form fields...

Hope this helps - good luck and best regards
Sebastian

 assets like RDBMS tables, WSDL Documents, POJO's or Entities as
 quickly as possible giving you options as to which project, source
 folder, and package you would like the generated code to go into.

 You can review videos of the GWT and other scaffolding options from
 ME4S in action here:http://www.youtube.com/user/myeclipseforspring

 Finally, we have an option to let you generate JUST the GWT front end
 and Service stub without requiring the use of any specific back end
 implementation includingSpring.

 ME4S can start from your existing Java code, WSDL, or RDBMS definition
 and generate reusable GWT front end components that are tied to your
 data model and which follow a strong MVP / Command pattern.  These
 components can be mixed and matched together to build more complicated
 downstream applications that go beyond CRUD.  The Remote Services are
 stubbed out to allow you to integrate with the server side technology
 of your choice, or you can accept the defaults and let ME4S build out
 a layered CRUD backend that includes JPA Entities, DAO’s, and Services
 all wired up usingSpring.

 I hope this helps, but let me know if you would like to have more
 detail.

 Thanks

Re: GWT and Spring - More Generation Options

[Niel]

Yes, it does use Hibernate.

The scaffolding functionality of  MyEclipse for Spring generates the
GWT front-end integrated with the Spring (Spring/JPA/Hibernate) back-
end application.  The back-end is a Spring application that uses
Hibernate as the JPA provider, and the Spring Services (@Service)
provide the RPC interface/services for the GWT front-end.  The GWT
front-end (MVP, UI Binder) is generated to call the Spring services.
The GWT portion of the application has no notion of JPA (or even
Spring for that matter).  If you are interested in Hibernate without
JPA, the back-end application can be refactored without impacting the
GWT front-end.

I hope that helps.

Re: GWT and Spring - with Spring Web MVC or without it?

[Richard Allen]

For operations like file upload which cannot be done with Ajax, GWT
provides no server-side facilities. With Spring MVC, you can easily
wire up a Spring Controller that handles the file upload request that
a GWT client submits to.

See: 
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-multipart

Yes, Spring MVC is a page-based framework with both server-side and
client-side facilities, and GWT is a component-based mostly client-
side only framework that was designed for web applications that
execute in a single page, such as Gmail, Google Maps, and Google Wave.
However, even an app like Gmail has a login page that is separate from
the actual application which submits a form post, then redirects the
browser to a separate page that loads the application. Spring MVC is
well suited for serving pages like that login page and handling the
form post.

Additionally, there is great benefit derived from using Spring Core
for dependency injection and AOP of your server-side code. All serious
Java web applications that I have worked on have significantly more
server-side code than client-side code.

Re: GWT and Spring - with Spring Web MVC or without it?

[George Georgovassilis]

I'll go with Stefan here.

MVC implies that the server handles much of the view - with a GWT
application the server is reduced to a glorified DAO. All you really
need is integrate services from the backend into the frontend. What we
really missing is something like RMI for the browser - GWT's RPC is as
good as it gests for this purpose and and libraries like the GWT-SL
allow you to directly publish Spring managed POJOs as services over
RPC into the client.

If you want to use GWT RPC for client server communication, there is no need
for Spring Web MVC. If you want to provide a RESTful API and use it for GWT
too, Spring Web MVC is a good choice for realizing RESTful APIs.

Re: GWT and Spring - with Spring Web MVC or without it?

[Richard Allen]

There is also the GWT Server Library from the GWT Widget Library
project: http://gwt-widget.sourceforge.net/

You should also check out the support for GWT that is now built into
Spring Roo. If you already use (or want to use) the technologies that
Spring Roo builds in, like JPA, then Roo will get you running fast
with a solid architecture that uses best practices:
http://www.springsource.org/roo
http://blog.springsource.com/2010/05/19/spring-roo-1-1-0-m1-released/
http://blog.springsource.com/2010/06/02/using-springsource-tool-suite-2-3-3-m1-with-roo-and-gwt/

I don't think there is one right answer to your question. How you use
Spring with GWT depends on your project and your team's preferences.
However, it is quite useful using Spring MVC (or some other Java web
framework) with GWT because GWT doesn't provide much server-side
facilities. In a large project, you are likely to need some static web
pages that do not use GWT, and Spring MVC makes that easy (among many
other things). Additionally, we have used Spring MVC controllers for
file upload and download, and to serve up resources from the
classpath.

I also believe it is very useful to avoid having your actual service
implementation extend from GWT's RemoteServiceServlet. Spring MVC
allows your controllers to be implemented as POJOs, and most Spring-
GWT integration libraries strive to allow you to use GWT RPC while
still implementing your services as POJOs. Some benefits to this
approach are the ease of unit testing POJOs and no dependence on GWT
libraries in your services.

Hope that helps,
-Richard

Re: GWT and Spring - with Spring Web MVC or without it?

[Brian Reilly]

I've had good luck with the second (non-invasive) approach. A coworker
of mine implemented the first (using Spring MVC) approach and it did
work for the most part. However, we aren't otherwise using Spring MVC
and don't have any broad expertise in it, so I was initially confused
when looking at it. Specifically, I didn't know about the relationship
between the servlet name and the -servlet.xml file, the contents of
which require some learning to understand (i.e.,
SimpleUrlHandlerMapping and its mappings property). I also didn't
like the additional wrapper GwtRpcController around the actual
service; it seems like an unnecessary layer. I think this setup keeps
you from having to extend RemoteServiceServlet, but you still have to
worry about GWT serialization of parameters and return values so I
don't see it as a big gain. Also, the proxy means that you lose
getThreadLocalRequest unless you add code to the GwtRpcController to
forward it to your service.

I like the non-invasive approach because it keeps the setup of the GWT-
RPC servlet exactly as explained in the GWT documentation. Your spring-
configured services don't change either. You just gain the ability to
inject those services into your GWT-RPC remote servlets.

I think it comes down to where you're coming from. If you already use
and like Spring MVC, you'll probably prefer the first approach. (I
hope someone with that perspective also responds to describe the
benefits of that setup.) If you like GWT and just need to integrate
with your spring-configured services, you'll probably prefer the
second approach.

Re: GWT and Spring

[olivier nouguier]

Server side or Client side ?

Client side you should take a look at GIN.
Server side, many solution exist IMHO I prefer solution without xml
configuration (annotation  detection based).
It very easy an instructive to build your own solution.
You can take a look at my (hobby) project
http://code.google.com/p/orcades-gwt-spring/wiki/orcadesGWTSpringHandler
http://code.google.com/p/orcades-gwt-spring/wiki/orcadesGWTSpringHandlerI
think this solution i rather simple.

GWT and Spring Security in Eclipse IDE

[Marley]

I am using Spring Security with my GWT application and have it
working.  however, to get it working in the Eclipse IDE i have to
include the gwt.codeserver in the url of my default-target-url as
in

security:http auto-config='true'
security:intercept-url pattern=/login.html* filters=none /
security:intercept-url pattern=/** access=ROLE_USER /
security:form-login login-page='/login.html' default-target-
url='/MyApp.html?gwt.codesvr=55.55.55.55:9997'  always-use-default-
target='true'/
security:logout logout-success-url=/login.html/
/security:http


While this works in development i do not want this in my production
environment.  Can anyone offer any advice?  I guess worst case i could
have my Ant build script overwrite that value when i build for
production although it seems sub-optimal.

Best practices/ideas for GWT with Spring Security (or equivalent)

[Paul S]

I would like to debate some ideas for how to secure GWT apps in
different ways and their pros and cons. It is important to remember
that there will be different needs and so different approaches will be
more suitable in certain cases, but I just want to be aware of what
people are doing.

I am using Spring Security because it is excellent, and whilst I am
aware that there are many other solutions available this is not the
focus here, so I'll just call it Security from here on.

Security offers protection of URLs and also some more fancy AOP style
protection like protection of specific functions. To keep things
simple here lets just look at protection of URLs.

1. Without Ajax - Protecting URLs that relate to pages

Before the days of Ajax where a URL effectively corresponds to a state
you can see how the model becomes straight forward. Adam accesses /
home.html, it loads and Adam gets to read a bunch of content. At this
point Adam is considered to be a Guest. Adam is curious about a link
called Administration, when he clicks it he is sending a Request.
That Request has some header info embedded in it (which the user never
sees but you can see if with Firebug or whatever). Sadly Adam is not
signed in so Security redirects him to a login page, but remembers
everything about that original Request. Adam suddenly remembers he
does have a user name and password so he logs in. Security processes
his login and then redirects him to the exact equivalent of what would
have been the original Request. Adam is happy because his work flow
continued seamlessly despite being asked to login.

(Ok, Spring Security can be configured to replay the original Request
upon successful login (default), or it can be forced to send you to a
particular default login success page. If you use the latter then
Adam's work flow will not be seamless because his original request for
the Administration page has been forgotten. Though sometimes you
might need a set up like this?)

Now Ajax comes along, and in particular I'm going to talk about GWT
here but the principles apply.

2.a. With Ajax - but still protecting URLs that relate to pages

If we use Security to protect the URL of container page (in GWT that's
the page that hosts the bootstrap javascript code for your GWT app)
then, just like normal if Adam visits /home.html he will be able to
read the content on that page. The Administration link has been
modified to take you to /admin.html which is in fact the host page the
GWT administrator module. Adam clicks Administration which Security
knows requires the Admin role so he is redirected to the login page.
Adam logs in and whether Security is configured to play back the exact
Request or whether you specifically move the browser along to /
admin.html, at this point doesn't matter. Adam is now looking at a
fully loaded GWT application. Lets say also that Security is told to
protect every GWT RPC call. Well Adam is logged in so he is allowed
access to the server services via GWT RPC and all goes smoothly...
until Adam leaves his computer for an hour and comes back to continue
his work. When the next server call that occurs is met by Security who
says, since your session has expired you are not logged in, so I'm
going to redirect you to the login page. XmlHttpRequest obeys the 30x
response code which is telling it to actually load the resource at /
login.html. In GWT this amounts to an InvocationException where the
error message content is your /login.html page markup. That's no good!
The XHR cannot interpret this as your browser would, so what to do?
The answer is pretty straightforward here. Design your /login.html
page to contain a text token that you can search for. So for example
in my /login.html code I have places an html comment right at the top
like this
!-- SECURITY-LOGIN-PAGE --
so when the browser hits the /login.html page it just looks like a
regular login page. But when the RPC call encounters this
InvocationTarget exception I have an onFailure handler that looks like
this:

   public void onFailure(Throwable t) {
  if (t instanceof InvocationException){
 if (t.getMessage().split(!--\\s*SECURITY-LOGIN-PAGE\\s*--
).length  1){
onLoginRequested();
} else {...}
  } else {...}
   }

My onLoginRequested() method could be any of a few styles. The most
obvious is to have it call a native method that looks like this:

   private native void redirectToLogin() /*-{
  $wnd.location.replace(/login.html);
   }-*/;

Now at this point we have to get clear on the behaviour of Security
with regard to where it redirects the browser after successful login.
In this case you would have to specify that it ALWAYS redirects you
to /admin.html so that when Adam signs in again he is taken back into
the Administration app. But sadly his page state (history tokens) is
lost and he's back on the front screen of your app and is now required
to put the app back into the state it was before (i.e. Adam may have
had some
