Re: authentication in GWT
In answer to the criticisms of HTTP authentication: 1. The generalilzations above about user experience don't click with my experience with users. No one ever reported a broken application on seeing the login dialog. THey really don't care if it's modal, if the background is grey, or any of that stuff that seems to drive developers to reinvent the authentication wheel in cookie-based sessions. 2. It's not that HTTP Auth is better than what you can build with cookies. I don't know if it is or it isn't. It's about not reinventing a stack that's already there and functioning. A decade ago HTTP auth was not well implemented across browsers, but that was a decade ago. 3. Digest Authentication does not send plain text, and is as easy to setup as Basic. The last paragraph, Reinier, the one that starts There really is no problem here..., I'm not getting your meaning. HTTP Auth is just another session that the developer doesn't have to program. But it's also a session that's maintained on the client, so it's consistent with the stateless server constraint of REST, and general network application scaleability. My application has a logout feature. It's a nice-to-have, especially for me if I have to troubleshoot the appliation from a user's terminal. But as a real security feature, it doesn't get much use. If a user has to leave her work area and is concerned about someone gaining unauthorized access, she is more likely to CTL-ALT- DEL,k (which locks the entire computer) than to start logging out of individual applications. It's easy to implement logout properly in IE, harder with other browsers because they don't support a clear identity cache function, but still possible. In fact, I wonder why it is that the other browsers are not better in this respect.

I thought you were referring to a more fine grained authorization scheme where certain widgets appear only for certain users. That sort of entitlement management goes beyond authorization, and the point I was making was that it seems somewhat orthogonal to what protocol you use for auth.

Re: Open url with POST parameters
What I am hearing here is that in the existing system, a response or redirect occurs after you POST to the action_script URL, which replaces the document in the current window. But you want to use GWT to make that same document open in a new window? And you have no control over the server side implementation? I think you're stuck. What comes back from the POST is a page reload, and that means your GWT javascript in the original page is gone. Did I misunderstand the plumbing? If you want to open a new window to a known location in GWT, it looks like this: Window.open(new_url_string, unique_window_name, ); I don't know if that helps though.

Re: Single application .. multiple RPC services
Muhannad, I agree with Litty and Gregor. Probably the best thing to bring clarity to you at this point would be for you to develop the canonical GWT single-page rich client application and use a single GWT RPC Service for all data needs. Get comfortable with that model (you can do a lot with it!) before you try to hybridize with standard page-load- page web application style. In particular, drop the idea of Service- per-URL. Yagni. Walden On Nov 6, 2:35 am, Muhannad [EMAIL PROTECTED] wrote: Hi Walden, I'm not sure that I got your idea, but I always had a concern about that so I'll share it with you: 1. Does the GWT application have just one html page (module-name.html) that all the content should be rendered there? What I mean is that Litty wrote if the URL ends with /about then the AboutService will be called. Well but what if that AboutService does not extends or consists of any UI element? What is gonna to be displayed on the browser? 2. What I've received from your idea above is, each service should have its own (index.html)??!! If that was the case, each time I click on a menu item then a whole new page is going to be rendered and the browser will send an HTTP request and page will be rebuilt and displayed, which is not the case here:http://extjs.com/Please try to click any menu item and notice that only a portion of the page is rendered (the section under the menu) and not the whole page. Actually, this is exactly what I need to do but I think I was not clear enough. 3. Suppose that I want to pass parameters in the URL in some customized format; not using the regular wayhttp://domain/service?param1=value1¶m2=value2. For example, something like that: http://domain/service/param1/value1/param2/value2. Where should I write my own code that should take care of this customized URL encoding?? I mean, is there any place in GWT application where I could capture the URL and manipulate it before redirect it to some place depending on some parameters passed?? I guess there is something in .NET called HTTP Handler or Generic Handler to deal with that. I think this is an issue that the Web Server should deal with it not the GWT application???!!!

When a user clicks on your about menu link, she's not going to get a Panel, she's going to get a whole new page fromhttp://domain/about/index.html. That page can be a GWT host file if you like, but this is regular HTML pages, not a rich GWT client showing and hiding content based on menu navigation. I think you'd better get your head around that first, and then tackle the RPC URL binding question next, if it's even an issue at all. Walden On Nov 5, 5:12 am,Muhannad[EMAIL PROTECTED] wrote: Hi, I want to build a website with (Home, about, products, ...) menu. I need to build multiple forms (panels), each panel corresponds to one menu item, e.g. aboutPanel for about menu item, productsPanel for products... Moreover, I would like to implement that panel in terms of RPC services; I need to correspond each panel to a single RPC service that communicates with the server to get its data, build the whole form, and return the result as a panel to be displayed somewhere in the home page (for example). Of course, GWT allows us to define multiple services and add multiple servlet path=/service ... to the module XML file. My problem is how to know which service should I instantiate depending on the URL mapping, i.e. suppose that the menu is defined as follow: div id=menu a href=index.htmlHome/a a href=/aboutAbout us/a a href=/productsProducts/a ... /div So when someone clicks the About us link, the URL would be http:// domain/about. So I should instantiate the about service and create an aboutPanel to display it. The same thing when s/he clicks the Products link, then the URL is http://domain/products; and, in this case, I should build the product panel... So, is there somewhere in GWT application that I could parse the URL and depending on the mapping portion of it /about or /products could I decide which service to instantiate? Or is there another better way to do that?

Re: can the gwt compiler compile files outside the module
AB, You could go that way. Cobbling together a module using a script will defeat some of your IDE features, though, depending on what IDE you use. GWT Modules are transparent and non-intrusive to javac compiling, so you should be able to accomplish what you need with a small number (one?) of gwt.xml files strategically placed in your existing hierarchy. If I were you, I would probably refactor for GWT/Java reuse, though. Take your util files, put them together somewhere in GWT module arrangement, include that location on the javac classpath if not already there, and inherit the module wherever your GWT code needs util services. It's not necessary for every Module to have an entrypoint. It's necessary that the transitive closure of inherited modules for a given compile have an entrypoint. Hope this helps, Walden On Nov 4, 3:13 pm, AB [EMAIL PROTECTED] wrote: Thanks all. I guess Ill create an ant task that cobbles together various util classes that we want and build a module.

Re: Event driven communication between independent GWT modules
Joe, You don't need DOM events, per se. Use Observer Pattern. Your Login module doesn't need to know who's subscribed. It just needs to implement the Observable interface (register listeners, fire login state change events). Your other modules are in fact dependent upon Login. They need to know how to register listeners, receive events, recognize Login events, and then I would suggest you let them probe the Login module directly for login state. If you look at how ChangeListener and SourcesChangeEvents work in GWT, there are all the elements of the Observer pattern you need, and you can copy that. Walden On Nov 3, 3:33 pm, JEA [EMAIL PROTECTED] wrote: I have a web site that has pages that each can contain a variety of independent apps embedded in a different positions within an otherwise conventional HTML page. Although independent, they can affect one another. For example, there is a login box that authenticates a user. Based on the user login status, the other apps may appear or disappear or change their behavior. Since a user can log in or out at any time, the apps should be able to detect the change when it happens and modify their behavior appropriately. The login box doesn't know what other apps are on the page so it can notify them directly. I didn't code all the apps as part of one large app because I didn't want them all to load for every page when only a small subset would be visible. My plan was to create some type of shared bulletin board object (maybe a hidden div with custom attributes set) on which the login box would post changes to the login status then fire a DOM event to notify anyone who cares. The other apps would register listeners to receive the change event and check for the status changes by looking at the bulletin board, adjusting their behavior appropriately. Problem is, I can't figure out how to implement this. I can see I can use eventPreview to process a DOM event but I don't see a method that lets a GWT module programatically fire an event on a DOM element. Is this possible in GWT or GWT-ext? Perhaps there is an altogether different and better way to achieve my intended effect. -Joe --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Event driven communication between independent GWT modules
Brian, I think it should be made clear that GWT Modules are reuse packagings, just like Java classes, and don't even imply a runtime application architecture. The only reason for breaking code into Modules is to reuse it by inheritance rather than duplicating code. Walden On Nov 4, 11:58 am, Brian [EMAIL PROTECTED] wrote: Err, size and speed were increased by keeping it in one app should have read, size was decreased, speed was increased by keeping all the modules in one app. On Nov 4, 11:56 am, Brian [EMAIL PROTECTED] wrote: I wanted to do something similar to having a bunch of independent modules interacting on a page, but gave up, and stuck with the monolithic app. I think you really need to analyze if it's worth breaking up the app into modules and trying to work with all this glue you'll need. For instance, there's quite an overhead in size for just a hello,world gwt app. You'll be paying this overhead for each module. Also, once the monolitic app is cached by the browser, it's there until cleared, so there's basically no penalty for having the app on multiple pages, even if it's not used that much (ie, not all modules are visible). Also, you can break up your monolitic app so you only create the classes needed in the given state, so you don't eat up memory for modules you're not displaying, etc, etc. It just ended up not making sense to break up the app -- What are the advantages to breaking the app into modules? Size? Speed? In my case, size and speed were increased by keeping it all in one app, and relying on browser caching.

Re: Event driven communication between independent GWT modules
@Thomas, If you could define *application* then I could figure out if I can make any sense of your comment. There may be confusion arising from my sloppy use of the term 'module'. I was talking runtime architecture, not code organization. So maybe I should have said 'component' instead. Anyway, to be clear, I was not talking about GWT Modules. I was talking about components with state, optional user interaction, and an event bus for implicit invocations triggered by other components. I think that's what the OP was describing. FWIW, I read the post below on monolithic solutions, and I concur with that approach, which is consistent with what I was proposing.

You say you're not that professional with GWT. The problem may be

MyDataStructure
for example:
private MyDataStructure my_data = new MyDataStructure();
public void OnModuleLoad(){
MyDataStructure = load_data_from_db();
.
b. pass this data structure to a child (not in terms of
inheritance, composition maybe) object (let's say MyObject) that could
manipulate this data structure (set some attributes to that data)
...
MyObject my_object = new MyObject(my_data);
...
c. display that object (MyObject) in some container, taking into
account its data (already passed by its parent)
...
Panel my_panel = new Panel();
my_panel.add(my_object);
...
2. on MyObject class
public class MyObject extends Composite{
private MyDataStructure my_data = new MyDataStructure();
public MyObject(MyDataStructure my_data){
this.my_data = my_data;
}
//here somewhere and depending on some actions MyObject class
could add some attributes to its data e.g. setVisible(false)...
}
So, I need, depending on an action button to reflect that changes on
that displayed object on the panel but I don't need the whole data to
be reloaded .. how could I do that?
Tell your MyObject that the MyDataStructure has changed and that it
should refresh. To do that, you could have MyDataStructure fire
events and MyObject register to handle them.- Hide quoted text -

Re: Tooltips for GridPanel cells
Sascha, It seems Tooltips and GridPanel are GWT-Ext features, so your question on that is off topic in this forum. It may be that you can just figure it out if you read the code though. For text underlining, check out CSS text-decoration. But again, to discover the hooks into GWT-Ext for applying that style in a data cell, you'll have to check the other forum or do your own homework with the source.

This is a plus if you're shuffling lots of data around, but I don't know how to define lots for you. - There's plans to make the deserialization of RPC responses asynchronous so you don't tie up the browser thread reading large responses. You'd have to do the same thing manually with large JSON responses. - Using RPC is a nice way of abstracting the transmission details and saying I don't care about the wire format of your requests and responses. This means client-server interface management is reduced to managing the evolution of a Java interface, rather than worrying about whether or not the client and server are in sync. It also means that some mismatches between client and server can be caught by the compiler. - It _might_ be easier to re-use an RPC server-side than a JSON server-side because the RPC-specific details are already pretty well isolated from the business logic.

Re: Httpsession and GWT
Hi Paul, Responses inline... On Oct 27, 6:50 pm, Paul van Hoven [EMAIL PROTECTED] wrote: Hi Walden, thanks for the answers. Sorry, I have to ask you again: You answerd: Once you've ascertained the user's identity and bound it to the session, sure. Do you mean that one should use the session object to identify the user for each request? Because my question was negated (...recommandable not to use a HttpSession...)? No, sorry. I read carelessly. First, I think using a session object to identify the requestor is not the best idea. Second, yes many applications do that, but what I was pointing out that this does not replace an authentication protocol. To my alternative suggestion: What I mean is when the user logs in then I generated a random id that identifies him a long as he is on my page. This means he recieves this id from the server on the login procedure and the server on the other hand also keeps this id. If the user now sends any request to the server, then the user sends everytime also this id, such that the server can verify that this user is logged in. If the user does not continue to use my webage then after for example 30 minutes or so this random id is deleted on the server side and the user is regarded as logged out. Or it is deleted when the user logs out manually. That is essentially your handmade rendition of a session token. It's no better or worse than JSESSIONID, provided that there has been a successful exchange of credentials. In fact, it's worse, because it intrudes into your application data semantics (ie., it pollutes your RPC requests). If you setup Digest authentication, the browser and the server would negotiate credentials following a login prompt, then all your future requests will carry both an identity and a credential (which can change over time), without you having to program those into your RPC API. If you need logouts and/or session expiration, then you will need to do some work.

Re: Integrating GWT application with existing java project
VK, For starters, why don't you create a 'gwt' folder in your source hierarchy that is outside the scope of all your Java EE classes, and preserve the canonical gwt project structure there. It could be just as simple as that. In future, if you have GWT remote services, you may want to move their implemtnations to your servlet folder, if you have one. There are other things you might need to do if you intend to share model classes between EJB3 and GWT, but let's talk about that later, as it involves creating additional GWT package(s). The important thing at this stage is not to try to shuffle GWT client classes in with other stuff that does not need to meet up with the GWT compiler. Keep life simple.

I've numbered the questions below: 1) If we can't trust cookies, what's the point of using cookies at all? If it's just so the browser UI thinks the user is logged in, why not just store it in some local client side variable since GWT applications are contained within a single page. * Make RPC call with user/pass * Server says pass = OK * In User.java, call setLoggedIn(true) 2) That leads me to my next question, how should the sessionID be stored in the client? Do I just store it in some class, let's say User.java as a String or whatnot in plain text? 3) Then, in any RPC request that needs the user to be logged in, I pass thissessionID along with the rest of the objects? 4) How does the server then take this sessionId and authenticate it? Is the approach the same whether I'm using Java/RPC with Tomcat or JSON with php on an Apache server? Can you give an example (or a link to a page the explains this?) 5) Finally, is there any situation where you would store the username/ pass on the client in order to authenticate each RPC call?

Re: module source path element
Step 1: Please categorize your java classes as follows: A. any class that will be compiled to javascript (including any class that will also be compiled to bytecode for the server) B. any class that does not belong to A. Step 2: Decide on a GWT module scope and location: ~/project/gwt/module1 That's the root of your module. In that folder, place your Module1.gwt.xml file Step 3: Create client/ and server/ folders to house java class categories A and B, respectively: ~/project/gwt/module1/client/ ~/project/gwt/module1/server/ Now build out your Java package structures under those, as you wish. You don't need the source path=... in your module file because client/ is the default. Some notes on what you've said above: 1. classes destined to webapp/WEB-INF/classes may come partly from category A, partly from category B. Make that separation at deploy time. You can use java packages below client to help separate pure client classes from shared classes, and write your ant scripts to copy by package. 2. your common bean, e.g., needs to be under client/, but can be in a java package recognized by your build script as needing to get deployed to the server. 3. your client code which gonna be translated to javascript must also be under client/, but can be (packaged separately so as not to copy to the server, although it wouldn't do any harm to copy these .class files as well. Here's a banal example of what I mean, but you can do better: ~/project/gwt/module1/client/pure - classes needed on client only ~/project/gwt/module1/client/shared - classes needed on both client and server 4. your module description needs to be at the root of the module filesystem, as shown above 5. your entry point is just another client side only file; see point 3 just above. That should do it.

Re: Does panel has border?
You can add a style name at any time. If the UIObject had no style
name at the time, that would be the same as setting style name.
You can set style name at any time. It blows away any pre-existing
style name(s).
You can only add dependent style name when there is a 'primary' style
name in place (see above).
So in your case, if you say fp.setStyleName(foo-FlowPanel), then you
can make up a css rule for .foo-FlowPanel {}, and you can also say
fp.addStyleDependentName(bar), and the full style name will now be
foo-FlowPanel foo-FlowPanel-bar.

Re: size of a unvisible widget
PopupPanel uses a different technique for setVisible. Since you're reading the code (good idea) you should read the comment there. By the way, I was wrong about deferred positioning, at least in the sense I meant it. I assumed there was a DeferredCommand down in there, but there isn't. 'visibility: hidden' allows the element to take up space in the layout without being visible, which allows its size to be sampled.

Re: RPC Collections Syntax
Service:
public ArrayListT getCollectionOfT(String stringArg);
AsyncService:
public void getCollectionOfT(String stringArg,
AsyncCallbackArrayListT callback);
Class T:
private ArrayListB bs;
public ArrayListB getBs() {
return bs;
}
public void setBs(ArrayListB bs) {
this.bs = bs;
}
Class B:
- nothing -
Something like the above. By the way, ArrayList is not by accident.
If you're not using any other list implementations, then for GWT don't
over-generalize the interface.

Re: Ant tasks ZipException
Isaac, Since the GWT compiler has specific needs pertaining to classloading, I think it's appropriate to try to manage the problem internal to the compiler. I have not looked at this in detail for a long time, so I was wondering if anybody on the list was more conversant with how this works. Your points are well taken. Maybe a warning rather than an outright fail would be better. Just something so people don't keep getting stuck in this particular bit of tar (I noticed another incidence of this on the list yesterday). The custom ant task is a fine idea, but its failing is that not everyone will use it, and we're right back here.

Is there a practical way of knowing if any given classloader would be compatible? Just giving up if you don't find one specific classloader would cause GWTCompiler to fail in any environment that replaced that classloader, even with a compatible substitute. What I can suggest is a GwtCompilerTask for Ant that I've started working on in the Incubator. It's very much an alpha version, but it works in my tests and handles forking automatically. You can find it in the Incubator trunk and I also did a quick write-uphttp://publicint.blogspot.com/2008/10/introducing-gwtcompilertask.htmlabout it yesterday. Feedback is very much appreciated.

Re: Collections of Serializable
Well, you're already doing that, but you don't like the performance
consequences.
I think the answer is to get out of the heterogeneous mindset. This
isn't Java. Adopt a less elegant looking solution in which you
structure up your responses using specific type references. How to
apply that strategy to your particular case is really a project-
specific design issue. There may need to be some give and take
throughout the design.
As a note, I've seen non-GWT Java projects in which the developers
(probably coming over from Perl) prefer to represent everything as
maps of objects. So instead of a class with clearly typed properties,
everything is a bag of anything. This pretty much defeats the purpose
of a strongly typed language, although you can get it to work. It's
like implementing everything through reflection.
So, if you take my advice above, you may also end up with a better
designed product, from an OO point of view, which means better compile
time error removal, etc.

Re: controlling outbound port range for XMLHttpRequest??
As far as I know, every OS out there has a primitives, available to programs through a socket library, which choose the ephemeral port for the client side of the binding when a client opens a TCP connection, cycling through the high range of numbers designated for that on each new connection request. It is unlikely that your browser is getting one of the low reserved numbers for its binding. More likely is that one of your custom applications has reserved something in the ephemeral range. That can work ok, as long as your custom application starts early enough to get its port bound before it's given out for some other purpose.

Re: Problem import class external path /client/ HELP!
You need to work on carefully separating classes that will be compiled by the GWT compiler from those that will not. Classes shared between server and client are in the first category. Isolate those under the / client folder before you try to configure your module. Then you won't need any source tags. If they cannot be isolated under a single path, then you will need source tags, but it will still be true that any location on the source path for the compile must not contain classes unsuitable for the GWT compiler.

Re: how to proxy all the methods in my RemoteServiceServlet
Dean, GWT RPC clearly does not have the security aspect designed in; it seems designed for use with an orthogonal security mechanism, such as found in the HTTP specs. A bit of a leap, but have you mentally walked through what would happen if you ditched SESSION-based security and went with Digest? I think this approach would sidestep a huge amount of custom programming for you. Question is, what would you be losing that you can't live without? In my application, if I start up a browser and type the URL of my RPC service (before authenticating), the JAAS system in JBoss issues a challenge from way down in the stack (my RPC code never sees it), and the browser puts up a login form. This is pretty much what should happen when your logged in user encounters a session timeout.

Re: Newbie question - adding GWT to my existing application
Suri, Let's take it one step at a time. The first problem is your source directive. It should look like this: source path=./ The path is the folder at the root of a hierarchy, not a single file. Since your path was defective, the Client1 source was not found, and that caused the import statement to fail the compile. The rest of the diagnostics you can just ignore. As for you later question, GWT does need the Java source (and does not need the .class files). GWT does have a limitation that inherited source needs to be packaged for inheritance. You can't just throw arbitrary jars at a GWT compile the way you can in actual Java. That's because of the limitations inherent in compiling to Javascript.

Your current Java code will have to be findable by the GWT compiler, which means there must be a .gwt.xml file on the classpath when you run the GWT compiler (you'll need to create that), and it needs to indicate where the compile sources are. There are basically two ways to approach this part: 1. keep your sources exactly where they are; place your Pkg1.gwt.xml file in the root folder of the smallest containing sub-tree for all the classes you need to include, and use the source path=x/ tag as many times as necessary to indicate (and hopefully isolate) just the classes you want compiled by GWT. 2. do a little folder reorganization so that the classes you will share between server and client side are isolated cleanly; have a 'client' folder at the root of that sub-tree, and place your Pkg1.gwt.xml file as a direct sibling to the client folder.

Re: redirect problem
Hi Dean, In my earliest prototypes with GWT RPC, I decided I didn't want to bother with failed calls, so I implemented my own AsyncCallbackAdapter which stubs out the onFailure with a Window.alert(). Then I extend that for the specific RPC cases. Strangely enough, I haven't had to revisit that decision. I think the same approach would work for you, except your default onFailure would inspect the exception to ascertain that it represents a session timeout, and then effect the location change to the login page. There would of course be a one-time effort to put this in place of what you have now. And you would still need to educate developers to always extend the adapter when implementing new remote services.

Re: Fire TableListener Event from inside a TableListener
Bear, I don't think it's covered by documentation, and I also don't think it's really a simple thing to do. I have implemented something like this relative to the 1.4 codebase, so it may not take advantage of features in 1.5, I don't know. One issue is that whatever you use as a cell editor needs to recognize the TAB key as a commit trigger (this assumes you let your user abandon a change in progress). Then you need something of a PositionController which maintains a cursor on the grid, and knows how to navigate the grid. For instance, a TAB would behave as you said, but a DOWN arrow might behave differently. To support such a PositionController, I found I needed to extend the Grid widget to instrument it with Keyboard and Mouse listeners, in addition to the Click listener. Then I let my PositionController subscribe to the events that can cause position changes, and so on. Hopefully you get the idea.

Re: GWT and servlet session
Sim123,
I'm sorry, I didn't write the GWTLogin Security paper, which documents
an approach other than what I use. I think that if you buy into the
idea of using session cookies for security (i.e., reinventing the
security wheel in order to get control over login/registration form
look and feel), then you need to go all the way and follow the advice
in the paper.
However, I'm suggesting a simpler approach, one which I'm using on my
project, which is simply configuring your server to protect the
resources you want protected using HTTP Digest authentication.
Depending on what your server is, find the documentation on
configuring that. There's not a whole lot more to it.
For instance, using JBoss/Tomcat for my web container, I deploy a
jboss-web.xml file that sits right next to the standard web.xml file
and contains the following:
jboss-web
security-domainjava:/jaas/digest/security-domain
/jboss-web
.
In the default JBoss configuration, there are digest-users and digest-
roles xml files. It's not difficult to switch to a JDBC-based
authentication, though, which is what I do.

Thanks for reply, actually I don't know where exactly the problem is,

First thing is : Compile/Browser option is not working when Filter is

request.getSession(false), if session exists request is valid other
wise I am throwing an error message saying session is null.
In hosted mode everything works fine, no issues at all.
Another thing which I noticed is strange behavior of
request.getParameter method in case of RPC. RPC method are http POST
method and now I am passing sessionID with request payload i.e.
another parameter in my method
public String getData(String studentID, string sessionID);
I am trying to get this sessionID in my filter's dofilter method
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) ServletException {

session = ((HttpServletRequest) request).getSession();

if ( session.getID().equals( sessionIDFromReq) ) {
chain.doFilter(request, response);
} else {
throw new ServletException(session is null);
}
}
}
The only thing I know is for some reason I am not getting sessionID in
filter even thought session is created. Please help, I hope I made
things little more clear this time.

Re: Combobox Display problem
Mark,
I'm not sure about your ComboBox. That's a Gwt-Ext widget, something
whose internal structure I'm not familiar with, and for support with
that you ought to consult the right group.
However, I can clear up a CSS misunderstanding for you. The 'dot' at
the beginning of a CSS selector means that the string of characters
that follow are a style class name, so .img would apply to elements
that look like this:
div class=imgstuff/div !-- this is not an img element --
That's not what you want. Without the 'dot', the selector refers to
an element type, in this case all img elements. The question is
whether you want that kind of margin setting on all images, including
those in your ComboBox. I suspect not. In order to cancel that, you
need to either override that same rule
img { margin-top: 0;}
or supercede it in the cascade with a more specific rule. For
example, if the img element in your ComboBox has a CSS class of
foo, then you can do
.foo { margin-top: 0;}
There may be many ways, depending on the tag structure and the
associated style classes, to accomplish this, but it entails detailed
knowledge of how the widget is composed and classed, which I don't
have.
Hope this gives you a start...

Re: common stuff
In my project, I have my own data proxy class that behaves pretty much like what you describe. It's a singleton that proxies all requests to the actual RPC (generated) proxy. It is the layer into which I make all RPC calls. It performs caching and notification for certain data queries. It supports a 'reference data set', which is expected to be static for the duration of a client session, which is retrieved once and cached. It has the ability to register listeners on certain data sets (including the refrence data), and will invoke their callbacks whenever that set gets refreshed from the server. Is this what you had in mind? BTW, Remember that after your code is compiled by the GWT compiler, it's not Java, and so Java class loading is the wrong paradigm.

Re: linkable resources, caching, xslt xhtml generation with embedded js
Hi Lawrence, That's life I guess. You still have some options, though. For instance, what if you create an alternate set of transforms that output JSON, and again just concentrate on outputting application data, not HTML elements. Then you can do RequestBuilder requests from your client to fetch application data, not pages, and still use GWT widget programming to control the UI. You really need to find a bridge from your current stuff to *widget programming* on the client, or else I fear that GWT will give you little for your investment. If your management wants to ride the web 2.0 wave, they're going to have to invest something too. It ain't free. Walden On Sep 30, 5:45 am, Lawrence [EMAIL PROTECTED] wrote: Walden, What you say is quite true. Transformation/XSLT is not ideal. However, our system is all written in C++ and generates XML. I can't change that. I can't put java on the server and I'm not sure it would make any sense. So basically no RPC, no serialization of objects .. i'm stuck with xml. The xml transformation is done by a stylesheet that is very old, about 750 lines of xsl. It takes the xml and transforms it in a xhtml form with tabs, fields, drop downs, etc .. Actually, it shouldn't be too hard to rewrite that in java .. its just about 1500 words. So I guess I will look into it..Its always hard to convince management that rewriting/refactoring something is *that* necessary..

Why don't you try writing a simple client in GWT that gets Java Objects from the server, and constructs Widgets to display information and ineract with the user? Calling a widget constructor automatically invokes the right code for the browser where your application is running, where doing an XSLT transform puts you back in charge of managing N transforms for N browsers. As a bonus, you get to design, write and debug your entire application as if it were Java, including the user's interaction with it. Who wants to debug an xslt transform session?

The old one was hand crafted to work only with IE6. The idea is to use gwt and get coding on business requirements rather than trying to work around all browsers .. but I have a few question : Currently we serve dynamic pages and we use ajax just to get notifications if something changed. We then recreate the page with the updated content and send it back to the browser. Part of this pages is generated via XSLT (on server) We have our XML data we transform it via xslt with our stylesheet (xhtml) and we return the new consturcted page. This styleshee converts our data to all sort of controls : checkboxes, date pickers, drop down, labels, buttons, etc. Every data page can be bookmarked. What I would like to do is recreate the web app via GWT, but instead of retrieving an entire page every time some data is requested I would prefer to only do an ajax request for the xml and then to the transformation locally on the client. I saw someone porting sarissa to GWT so this should be possible. The only problem is that we embedded quite a few js calls in the stylesheet, and those now will need to be handled by GWT rather than the old, IE6 only, js scripts. I know that gwt compress/obscure the output js to make it faster, so I wonder, how can I mix the two ? Is it possible ? Also, if I do everything via ajax/xml, does this mean people can no longer save link to pages, bookmark them ?

Re: Newbie question - adding GWT to my existing application
Suri, If the current Java code is in the same project where you are adding GWT on the client, you don't need a jar. Your current Java code does have to be sanitized to meet the 'closed world' requirements of the GWT compiler. Read the documentation on the GWT compiler and JRE emulation classes for details. Your current Java code will have to be findable by the GWT compiler, which means there must be a .gwt.xml file on the classpath when you run the GWT compiler (you'll need to create that), and it needs to indicate where the compile sources are. There are basically two ways to approach this part: 1. keep your sources exactly where they are; place your Pkg1.gwt.xml file in the root folder of the smallest containing sub-tree for all the classes you need to include, and use the source path=x/ tag as many times as necessary to indicate (and hopefully isolate) just the classes you want compiled by GWT. 2. do a little folder reorganization so that the classes you will share between server and client side are isolated cleanly; have a 'client' folder at the root of that sub-tree, and place your Pkg1.gwt.xml file as a direct sibling to the client folder. Then you don't need source tags. Try that, report any errors you get, and we'll sort it out from there.

Re: GWT with struts
Yes, and it usually makes sense to approach this in a two-tier fashion: 1. Client Tier. Depending on what roles your user is in, the screen you paint for them should not even contain the links or buttons used to invoke operations or services they are not entitled to. In my application, I push entitlement information out to the UI so these decisions can be managed there during the rendering of a screen. For example, I have a Portfolio Browser which, if the user is in the Trader role, supports a right-click context menu which supports trade order entry. For all other users, the context menu is never even created. 2. Server Tier. You can implement the same role-based authorizations you currently have on the server. Your single entry point action class sounds a lot to me like the equivalent of a ServletFilter. The client side authorizations should mean that a request never fails on the server due to unauthorized use, but it is safer to have more than one checkpoint. So the answer is Yes.

Re: FlexTable odd behavior
Grundle, Whenever things that should obviously be displaying are not, the first thing I do is dig into the document's structure using a DOM inspector to see if the elements are even appearing. If the elements are not there, then there is a procedural problem with your code. Maybe you can single-step it in Hosted Mode to see why your widget is not getting attached. If the elements are there, then it is usually a styling problem, and again you can use the DOM inspector to see what styles did actually get applied, and then trace those back to their source -- a CSS sheet, or perhaps an inline style that was set in code. Finally, the code you posted is not the real code of your application. This is evident in the way you are using FlexTable as though its methods were static methods. If you post code other than a literal copy/paste of your actual code, you are probably hiding the best clues anyone could use to find your problem.

Re: GWT+JEE+jBoss
The best system to develop on depends on what you know about the ultimate production platform(s). For instance, I don't develop on Linux because I know all my users will be using the product on Windows, and in IE7 for that matter. Even though my deployed server environment is Linux with Oracle database, I do my JBoss development on Windows using MySQL. I have found the JPA layer sufficiently neutral that I don't get bit often. Also, I develop on a laptop, and I like having a completely self-contained and mobile development environment that I can crank up in the shoe store while waiting for my wife to make a decision, if need be. Rapid feedback is a key quality in a development environment. I set up my RPC like this: 1. My service servlet has a 2-phase service location algorithm: it finds JBoss JNDI first on a well known port, then it tries to get the local EJB, and only if that fails it gets the remote EJB. In production, it will end up using the local; in development the remote, which is fast enough for testing. 2. When I test in Hosted Mode (launched from IDEA in debug mode), I have the shell/browser/servlet in one JVM and JBoss/EJB in another. 3. Client side code changes can be quickly refreshed and debugged in hosted mode. I do a lot more fidgeting with my client side than my server side, so the main part of development testing is this. 4. If I need to patch a server class, I start a second remote debug session to JBoss and let IDEA do hot code swap. This works as long as the Java schema does not change, else I have to re-build and deploy my server, which does incur a slightly longer wait (about 1 minute). 5. When the widgets are stable and the client logic is working, I switch to Compile/Browse to fine tune CSS in a real browser, where feedback is lightning fast, much faster than refreshing the shell.

IThe error I am getting is: Resource not found: images/imagePath/Image1.jpg could a file be missing from the public path or a servlet tag misconfigured in module The images folder is in the public folder of the Module that display the images. I upload images from another module and sometimes from the same module. On Sep 23, 8:56 pm, walden [EMAIL PROTECTED] wrote: You have a successful image upload, and then the server can't find it? Or is it some other kind of file not found?

I was searching for a way to view the image but I could not view any image that is uploaded in the session that I am trying to view it in. I am getting the error file not found. If you have any idea how I can solve this issue, I will appreciate it. Thank you. On Sep 23, 4:15 pm, walden [EMAIL PROTECTED] wrote: GWT is not Java; it doesn't have dynamic class loading. Maybe someday. In the interim, is there a way to describe your goal without making technology assumptions like this? Maybe there is a way to get the behavior you want using GWT in its current form, but you'll need to say more. Also, the in a new Window is not usually the best way to design with GWT.
