Re: How to use JavaScript to customize both the client and server in a consistent way?
It's true that I can hand-write these explicit bindings for client and
server, and if I can manage to unit test it, it might not be too hard to
maintain, but the writing of these bindings is what I wanted to avoid. It's
looking more and more like I can't avoid it.
For security, I embedded Rhino on the server and implemented a ClassShutter
(http://blog.notdot.net/2009/10/Server-side-JavaScript-with-Rhino) to
restrict all classes except java.lang, and may add a few others. I'm not
yet 100% convinced that this is enough.
I still would _really_ like this to work client-side, if possible, because
while getPrice could be a server call, I have cases where I'd like to call
the customer's script repeatedly to test for something across multiple
dates, for example, which would mean many round-trip calls. Yes, I could
architect the call to call the server only once, but so far doing this
client-side still seems the easiest and lowest latency way, if it's
possible.
In my case, getSomethingUseful is just a placeholder for many methods. I've
got a number of custom methods on my own BasicDate class I've written, for
example (because I need a consistent date class between the client and
server, and since there is no java.util.Calendar on the client side, and
the Date methods are deprecated, using those is too risky.) I would rather
they just be able to call into the classes that I allow them to.
I like Groovy, and wish it could be made to work client side. I'm going to
try this custom glue / explicit bindings approach with JavaScript, and if I
get lost in the woods, I might end up right where you are! Thanks for your
response.

Thanks for the idea. The options expand if they can call back to the server, but I was trying to make something work both client and server side.

determine if running on client or server OR synchronize time on server/client?
Hi,
my chess application should trust only the server time.
However, I have a shared class that is used both on server and client.
Within this class I determine the current time by creating a new Date
object.
When running on the server, this object represents the correct time. When
running on the client, I would like to synchronize it with the server
before using it.
But how can I tell if I am running on the server or the client?
Below is a short pseudo code for illustration.
Thanks

{

d = new Date (ms);

sharing XML binding classes between client and server side of a GWT-RPC app (no need for marshaling/unmarshaling on the client)
Hi, I've seem the same question a lot of times in this list, but no answers to the problem of having XML documents on the server side of a GWT-RPC application and binding classes that can be reused on the client side. The use case is as follows: - Binding classes automatically generated from XSD schemas. - Marshaling and unmarshaling occur on the server side (no XML to class/class to XML conversion takes part on the client side). - XML documents are consumed on the server side (client side consumes Java classes). - Binding classes consumed both on the client and the server side of the application. - GWT-RPC. What is a valid approach to share XML binding classes between client and server side? I've tried with JAXB, JiBX and XMLBeans, but always find problems with the serialization of the binding classes. All these technologies produce classes that implement Serializable, but for one reason or another, GWT fails to serialize them.

Hi Everyone, I have a requirement that, I have to search something from the db and get back some results(Like a search button functionality).For this I am giving some inputs. I have to send these inputs(like Beans) to server side. I am using GWT2.4 request factory. How can i do this? do i need to use value proxies here? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

do i need to use value proxies here?

Thanks for the reply. I have one more small doubt. Shall i use the same proxy for the return result. could you please provide me the sample for this criteria.

Re: sending data from client to server
Shall i use the same proxy for the return result. Sounds like it doesn't make sense but I don't know your app nor what you want to search. If you search for some data in your database then you probably want to return a list of EntityProxy-s as a search result (if you want to display the search result). If your search is more like a server side calculation, e.g. How many matches do I have for that search query?, then you would return an Integer for example (or a ValueProxy / List of ValueProxy if the result is more complex and does not represent a database entity). -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Is it possible to transfer list of EntityProxy between client and server using Requestfactory
HI:
Just like below, Is it possible to transfer list of EntityProxy between
client and server using RequestFactory? i didn't see any spec related to
this in RF doc. And i always get NPE when using maven processor plugin to
validate. Thanks.
@Service( value =foo.class, locator = bar.class )
public interface CustomerRequest extends RequestContext
{
RequestLong count( ListString searchparams,* ListMyEntityProxy
parent* );

Why don't you use the com.google.gwt.regexp.shared.RegExp on the server too?

Re: Bean Validation: Client vs Server
I thought about just using RegExp on the sever, but it just seemed wrong to rely on that on the sever. Not sure why, since I'm pretty coupled to GWT in any case. :) The super-source idea is interesting. I didn't know about that feature before. Googling it, it seems pretty interesting.

Re: Bean Validation: Client vs Server
Yeah, String.matches only matches the entire input. I need to see if the string contains a regular expression, as in pattern.matcher(string).find().

How do I throw all kinds of objects back and forth between client and server?
I want to be able to have the same object do client-specific behaviour when on the client-side (UI etc.), and do some server-specific behaviour when on the server-side (database etc.). So I want the same object to hold both a Widget (unused/null on the server side) and a server-specific Java object (unused/null when on the client side). To achieve this, do I have to create some dummy GWT emulation for the unused/null server-specific object on the client side and can I do the same for the unused/null Widget on the server side? Or does it work straight out of the box when you put it in the shared package? If not, what's the best way of making this work? My reason is simplicity. I don't want to have to put their respective client and server behaviours away from the object. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Or does it work straight out of the box when you put it in the shared package? shared is nothing special, just a convention. There's no such things as shared code in GWT; everything that GWT sees (in the source/ paths of your modules) has to be translatable to JS (i.e. client code); the client vs. shared vs. server is just a convention, where server code shouldn't use client code, to make it clear which code an run in both a browser (compiled to JS) and standard VM (server, or possibly Java client, such as Android, an applet or a desktop app). But having a field of type Widget won't harm as long as you don't initialize the class (i.e. use it); so there's nothing special to do on the serer side. My reason is simplicity. I don't want to have to put their respective client and server behaviours away from the object. But then you don't have a clear separation of concerns, as a single class plays all shared, client and server roles, where client and serer are mutually exclusive. You'd probably better abstract things behind an interface, and implement it in both your server-side specific object and your widget. It would have the benefit of adding testability of your code using a mock of that interface. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Pack as much as possible in the shared code, that is, to the extent the emulated JRE admits of. Have helper classes in your server side for database etc and in your client side for UI. This is close to developing a client-server application in java swing. The emulated JRE has nice java.util.Collection which is handy for domain modelling, UI handling and persistence. I think this is not only a simple way of developing but also maximally takes advantage of GWT.

Trying to get the simplest communication between the client and server.
I'm new to GWT and trying to get the simplest project under my belt.
I've got a project that does nothing but send a string from the client
to the server. The server adds a string to that string and returns
it. I've been spinning my wheels on this for days and don't know
where to go from here or what to even ask at this point. I've read
numerous tutorials and sample projects on the subject and it all makes
sense.
My project compiles fine. Then when I try to run web application i
get the following message in the browser (Chrome):
HTTP ERROR 404
Problem accessing /MyGWTModule.html. Reason:
NOT_FOUND
I also get the following warning in the eclipse console.
[WARN] No file found for: /MyGWTModule.html
[WARN] No file found for: /favicon.ico
I compile and then run web application. Am I missing a step?
If I zipped the project would someone be willing to take a quick look
at it (via email). Or let me know if there's a better way of sharing
it. Meanwhile, I'll post the project files in this post in hopes that
it will be enough for someone to help.
Also, could someone fill me in on what the Util class is for in the
MyRemoteService interface is for?
Thanks, the help is much appreciated.

Aw: Trying to get the simplest communication between the client and server.
I think your code looks fine. Do you actually have a MyGWTModule.html file inside your war folder or any html page that includes the generated .js files from GWT? If not you have to create one (New - HTML Page. The one with the GWT icon). You can also create it by hand. Just make sure you have script type=text/javascript language=javascript src=your module name/your module name.nocache.js/script in the html page's head tag and if you ever want to have history support you need iframe src=javascript:'' id=__gwt_historyFrame tabIndex='-1' style=position:absolute;width:0;height:0;border:0/iframe inside the body tag. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Trying to get the simplest communication between the client and server.
Thanks for the response. Yes, the HTML file and the CSS file are there in the war fiolder. It was created manually when I generated my GWT module. Possibly the path is messed up somewhere? I also tried to create a new HTML file as you suggested (not manually) and when I clicked on finish, nothing happened. Any other ideas?

Caching large datasets on Client or Server?
Hi there, I am struggling in finding a good solution for a caching method in my application. The client is sometimes retrieving more than 5000 rows which will be displayed in a pageable grid for now. In my first solution everytime the users clicked on next page the server only send the data snapshot of this side which works ok. But it always gets the complete dataset from the database. Now we are adding sorting which should also be done on the server. My question is now what is the best strategy to follow here? I thought about caching the complete 5000 rows on server side but I really dont know how to do this as the server is stateless. The only thing I have is httpSession to identify but i dont know if its a good idea to store this cache in a httpsession. Another problem is that my app supports a filtering option which could change the data of 5000 rows so the cache would be invalid. Is it a good idea to cache to rows on client side? I am not sure as the sorting would be done in Javascript right? Thanks for your help -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Problem in sending large size of data from GWT client to server by cross domain scripting
Dear All, I have followed the tutorial and the application is able to make cross site communication with GET request and query string in the URL. However, one of the function of my application is to send the XML String to the server from the GWT client in cross domain environment. The GET request cannot fulfill my need as it exceeds the standard query string size. What should I do to make it work? Can I make a post request to the the servlet in cross domain environment? Please kindly show me some tips on this. Thanks a lot. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Problem in sending large size of data from GWT client to server by cross domain scripting
There are tricks using a hidden form (FormPanel in GWT), but well, they're a bit hackish... (what's hackish is communicating the result back to your app: you have to send a redirect to a page that's the same origin as the app, and this will call 2 FormPanel.SubmitEvent to be fired; or you could use the window.name trick...) Maybe not that helpful to you as i'm a bit vague, but the point is: yes, it's possible. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How to get hand on serialized data sent between Client and Server (using GWT RPC)
Hey there, i would like to ask if there is a way to get hand on the serialized data sent between Client (RPC Call with AsyncCallback) and Server (RemoteServiceServlet) to do some stuff with it ;) For Server-Side i found that i could overwrite the processCall() method to do execute my desired code on the serialized data. But i have no idea how to achiev this on clientside. all i found until now is the com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.class in gwt-user.jar having a onResponseReceived() method where i should be able to do my stuff inside, but here i have no idea, how to get my class/method in place of this original code. Is there a way, to modify the request data sent from my client to the server, and also the response from server to client?

Data Structure between client and server
I have just started working with GWT, for an University Project. I have to create a classic client-server sistem. The client and the server must communicate exchanging some information.

How to automatically download image to client from server when button clicked
I am having the user click a button that will generate a report on the
server side. The report has embedded charts and graphs but since the
report is generated server side with BIRT libraries, when I return the
report as an HTML string, the images aren't displayed. What I'm trying
to do is have those images downloaded to the user's machine
automatically and then adding an image widget to the panel to display
the charts and graphs. Is there some sample code I can use to do this?
I have the server side servlet code I found from and example and
modified it for my code. I am missing the client side code. Can anyone
help? Also, I'd appreciate any suggestions or advice if I'm not doing
this correctly or if there's some better way to do this.
Server side:
public class FileServlet extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse
resp) throws
ServletException, IOException {
// set the responses content type
resp.setContentType(image/svg+xml);
// set the header for the response
resp.setHeader(Content-Disposition, attachment;
filename=image.svg);
// get the output writer
PrintWriter out = resp.getWriter();
// display a simple message
out.println(This is the output content);
out.println(Probably something dynamic should go in here);
}
}

I'm looking at this as if Entitiy/Value classes on the server implement EntityProxy/ValueProxy interfaces declared by the client. Even though Entitiy/Value classes do not implement the interfaces using Java *implements * keyword, the implementation is enforced by the GWT compiler. This makes the server classes completely decoupled from the client interfaces while the contract is being enforced at the same time. This system is more flexible then Java-based implementation because it allows using legacy server classes with the new GWT applications.

Re: How to solve this design problem, when using RequestFactory ? (how to enforce client and server to use same interface)
Thank You. I am trying to breaking my app into: client, server, and shared modules. in the shared module, I would like to put RequestContext, and Entity/Value Proxy interfaces, as well as server side Interfaces corresponding to RequestContext, for example, this shared module: EmployeeProxy - used by client EmployeeRequest - used by client EmployeeService - used by server, conceptually equivalent of EmployeeRequest and then on server modules, I implement interfaces defined in the shared module above (EmployeeService for example) but not doing anything about EmployeeProxy and EmployeeRequest. because they are going to be implemented by client. so although the module is shared, client and server implement different interfaces. this made me wonder, whether I have to make it a shared module after all ? what do you think ? do you think this way of partitioning is ok ?

Re: How to solve this design problem, when using RequestFactory ? (how to enforce client and server to use same interface)
Breaking the app into server, client and shared is a right thing to do, but placing proxies, requests and services there does not seem right. Proxies and requests belong to the client, services to the server. Shared packages should contain code used by both the client and the server (common constants, enums, common algorithms, etc). When using request factories, there is no need for DTOs in the shared packages. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How to solve this design problem, when using RequestFactory ? (how to enforce client and server to use same interface)
It is often recommended that, it is a good practice, for components, such as client/server communicate through interface. when working with RequestFactory, we need to define RequestContext, which makes use of Entity/Value Proxies. these are all interfaces. however, Server side code, cannot implement this RequestContext interface. server-side code, has no notion of RequestFactory, EntityProxy, etc. in other words, client and server do not implement the exact same interface, they use a conceptually equivalent interface, but it is not the same. if we think of client/server being separate projects, how can we enforce the contract ? I would like to have a shared interface FooService, declaring my services or DAOs, (findFooBy(id)) and use ClientFoo implements FooService ServerFoo implements FooService ClientFoo uses RequestFactory related code, ServerFoo, a serverside framework but these two communicationg through SAME interface, not conceptually similar. is this possible ? (I'm afraid it is not, what can be done to minimize the impact) ? Thank You -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Client en Server side validation
I've got 2 types of validation. Syntax and business rules.
The syntax can be solved in the presenter, but i don't want to
validate the whole bean if i only want to validate one property of
that bean.
I'm thinking to make it like this:
Class Foo() {
Date date;
String otherfield;
public validateAndSetDate(String textFromWidget, Error errors) {
// try to make the string into a valid date with some date utils
if not ok, than fill the errors object with an error message
}
Now i can try to set the value after a onBlur() in the presenter to
try to update the model (Foo)
But i want to do the same on the server after a RPC call because the
user could possible tamper the data somehowshould i than check all
the validateSetters? of all my properties with
validateAndSetDate(foo.getDate.asString(),errors) ??
I would be nice that i only check the changed properties after my last
RPC call. Any ideas?
Thanks.

Client en Server side validation
Hi, there has been a lot of discussion already in this group about validation and the frameworks that can help with it. Now i'm in a big project which need form/field validation onChange focus events and the same field validation need to be done on the server when the domain objects are being send via RPC to the server. Based on the concept: Always validate your input. The data coming in on the server is also input that we want to validate. Is this a right approach? If so, why can't i find this issue more spoken of...or does anybody thrust the rpc input? How do you slove this problem? If i make the presenter responsible for validating the widgets input, how does i know on the server which validator to use because on the server i have no presenter. Do you have patterns for this problem? Thanks, Jeroen Wolff -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Client en Server side validation
The correct thing to do, in my mind anyway (admittedly an odd place), is never trust a client and do your own validation of the data and operation requested. This contrasts with my professional experience, which has been that pretty much everyone just trusts the client and mindlessly follows its directions. I should mention that most of the applications I have dealt with are internal to an organization, so a rogue client isn't as big of a risk there. -Ben On Jan 19, 2:06 pm, Jeroen Wolff jeroen.wo...@gmail.com wrote: Hi, there has been a lot of discussion already in this group about validation and the frameworks that can help with it.

Re: Client en Server side validation
It depends on what you mean by validation. If you mean that the data conforms to the business rules then IMO you can validate on the client and all you need to do on the server is authenticate the user. A practice that I follow is storing the user's session id in encrypted form on the client. I obtain the session id on the server when the user first authenticates and I encrypt it and send it back to the client. When the client communicates with the server I send the encrypted session id as part of the data payload to the server where it is validated again the user's current session id. If it isn't the same I force the user to login and authenticate.

Re: How to use JSONObject with common code shared between client and server
Sorry, under com.google.gwt.json.client

The whole point of using JSONObject is that I have a java API that I
can use to marshall/unmarshall DTO objects regardless if I'm sending
them from client to server or vice versa.

Hi everyone,
I have a class that I want to share both with client and server code,
in my particular case it's the JSONObject.
It has different implementations on client
(com.google.gwt.json.client.JSONObject) and server
(org.json.JSONObject), but same interface.
So I have a DTO class like this shared between client and server, so I
can use JSON to pass objects around and wrap them in JSONObjects for
easy API access:
class Person {
String firstName;
String lastName;
public JSONObject toJson()
{
// code to convert firstname + lastname to JSON
}
public fromJSON (JSONObject x)
{
// code to read from JSONObject and set firstName and lastName
}
}
There is no way for me to tell GWT to use
com.google.gwt.json.client.JSONObject when compiling this class on
client, and likewise use org.json.JSONObject on server. I would have
to resort to Java String.
Now I could do the following, but I would have to re-write the toJson/
fromJson methods for each implementation - not acceptable to me!
class PersonBase
{
String firstname;
String lastname;
}
class Person_Client extends PersonBase
{
public fromJSON (om.google.gwt.json.client.JSONObject x)
{
// code to read from JSONObject and set firstName and lastName
}
public com.google.gwt.json.client.JSONObject toJson()
{
// code to convert firstname + lastname to JSON
}
}
class Person_Server extends PersonBase
{
public fromJSON (org.json.JSONObject x)
{
// code to read from JSONObject and set firstName and lastName
}
public org.json.JSONObject toJson()
{
// code to convert firstname + lastname to JSON
}
}
There must be an easier way!

Re: Client Vs Server and Google app engine
Hi, I would also advise you to give a try to Objectify: I abandonned jdo for it. Very efficient and much simpler!

Extra methods do not affect the serialized size.

Re: How to determine if running on client or server?
Make a factory, in the client code initialize to a client- implementation creating factory, and on the server to a server factory. Note that to pass it through RPC you'll need to use/convert to the client side class.

Re: Sharing code between client and server
You may try to:
1) Find a library which could be compiled/run for both client and
server sides
2) Use generic type (then wrap/extend it for client/server) such as:
public class XmlUtilsNode {
public String getTextNodeValue(Node node) {
Node txNode = getTextNode(node);
return (txNode==null)? : (txNode.getNodeValue());
}
}

Sharing code between client and server
I have some XML helper functions that I would like to share between
client and server. For example:
public class XmlUtils {
public static String getTextNodeValue(Node node) {
Node txNode = getTextNode(node);
return (txNode==null)? : (txNode.getNodeValue());
}
}
The only difference between client and server versions is:
import com.google.gwt.xml.client.*;
vs.
import org.w3c.dom.*;
What would be the simplest way to share as much of the XmlUtils code
as possible?

RPC communication between client and server running different GWT versions
Greetings! I'm trying to develop my first web application that uses GWT. I'm using GWT 1.7.1 to develop the client, since I'd like to use SmartGWT and it requires at least GWT 1.5.3. However, my server is running JRE 1.4.2. Therefore, I can only use GWT 1.4.x. To achieve this, I'm generating the client-side stuff with java 6 and GWT 1.7.1. Then, I create my servlet with java 1.4 and GWT 1.4.62. Unfortunately, this does not seem to be working. It works fine when I have the server using the same GWT/Java version... but when I switch to an older version it's not communicating. I tried to check the release notes to see if something changed in RPC communication, but apart from generics I couldn't find anything relevant. Eitherway, I think I'll check version 1.5.3 for the client.. the closest version to the server's that fits my needs. It may be some other issue, but if some one could tell me for sure that it is/it is not possible to get/send data via RPC under such conditions I'd be very grateful!

For that purpose I created a shared package (com.app.shared) in which to put the Contact class. But gwt (client side) only sees classes in com.app.client package. How can I use the Contact class on client side for the com.app.shared package? Do I have to add a inherits tag in my .gwt.xml file ? Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
