Re: Please help
Hello, You've managed to hit the most common problem that new GWT developers run into. Here's the deal: GWT is written in the Java syntax (which is really cool) and then the GWT compiler converts it into Javascript (since it is running in a browser). So here's the common mistake: not all of Java's huge library base is convertible by the GWT compiler into Javascript. What that error is really saying is you are importing a Java library that GWT can't convert into Javascript. java.io is one of those libraries that everyone wants to work in GWT, but I don't think will ever happen (I'm not affiliated with GWT in any way..) If you think of what java.io can do, it is completely contradictory to what the browser is allowed to do to the native file system. Said another way: there are many things that the browser is explicitly not allowed to do, and reading the local file system is one of them. So if you are going to absolutely need this functionality, you'll have to do it another way using another technology Does this make sense?

Re: Does Timer class only last one session + images as an attachment in an email
Here's how I'd do it...and it has nothing to do with GWT. You server side impl class is just a java servlet with a bunch of methods (assuming here...). At the beginning of each method, add a call to another method, call it checkAndDeleteImages().. Inside that guy, go to your database with today's date and query all images that have a creation date (or something similar) of today - 2 months. Get those images (blobs?, strings?, what?) and fire up good old javamail (javax.mail.Message in particular), create a message (probably MimeMultipart if I remember correctly for the attachment), point it at a valid SMTP server and send. When complete, delete the images. Add this method call to every server side method callsometimes you'll check seconds after checking...if that's oppressive, create a stateful bean on your app server with the timer. Don't try to do this in your client code...you'll go nuts and cause yourself a bunch of head aches, in my opinion.

Re: Problems releated to javaMail in GWT application
One of the biggest concepts to get your mind around with GWT is that while you develop everything in Java, in the end the GWT compiler converts your Java into Javascript (mostly, but some CSS HTML too). So when you create a Java class called foo.java, what will result is something like foo.js. So if in foo.java, you use java.lang.String, you think you're using the one in the standard Java JRE. But you're not. What GWT has is a large set of JRE emulated classes, written in Javascript. So the compiler knows how to convert java.lang.String into something appropriate to run in a browser. So in foo.java, you do what every good Java developer does and import something like javax.mail.Message and so on, and crank out some beautiful code. And you then ask the GWT compiler to convert that into Javascriptand it can't. It has no idea how to do javax.mail type of things in a web browsermostly because it can't. The browser is a heavily constrained runtime environment and things like filesystem access, port/packet operations (which I believe javamail does down in the bowels), data access, and whole bunch of other Java stuff can't be done in Javascript, in a web browser and therefore GWT can't do them on client. The only way to achieve this is to build a GWT client that communicates with a GWT server (preferably with GWT-RPC, but that's your call) where you can run full fledged Java and are not bound by the issues inside a web browser. I write this a lot, but it's worth mentioning again: this is not a limitation per se of GWT...all web browser based clients that run natively in Javascript are bound by the same security rules. Plugins like Flash, Silverlight and Java Applets are outside of this control umbrella. The amount of Java that is emulated in Javascript by the GWT compiler is staggering, but not infinite... Hope this helps. Later, Shaffer On Jun 4, 11:57 am, samounas elmokhtari.as...@gmail.com wrote: Please can you tell me how to use javaMail in gwt application.

Re: GWT Design Problem
Just a quick response...sorry I don't have time at this second for a more thorough one... Items 1, 2 3 are hardly unique to GWT...you've described the standing challenges that DHTML/AJAX clients have dealt with for literally the last 10 years. GWT does have some advantages, especially in history because of the way that the GWT team engineered the whole History subsystem. Item 4 sounds like more of a setup issue for your GWT app as you can use or not use as much standard CSS as you want. We currently have a number of mixed apps consisting of GWT JSP's, using the corporate standard CSS stuff with no issues at all. If I survive this impending 3 hour meeting I might be able to respond with more detail.

Re: GWT RPC calls from java

Re: Opinions on GWT as a platform for web based development
My .02... To Chris's point or if they're written in JavaScript, you won't have much lock-in...true. But you won't exactly be using GWT to it's strength. IMHO the advantage that GWT has over other frameworks is that it's not really a framework like YUI, Scriptaculous, jquery or whatever. Those are Javascript libraries to help you write slicker Javascript for the web client. GWT takes a different and wholly unique approach by nearly eliminating the need for developers to write Javascript in the first place. You write GWT in Java, using nearly full powered Java syntax and let the GWT compiler make the Javascript. You wouldn't be limited or locked in, any more than if you crafted your application around any of the aforementioned Javascript librariesso that means yes. Yes you are locked in, just as locked in if you developed an app in YUI and decided to switch to JQuery. The big, big advantages to GWT are syntax homogeny (Java for the client, Java for the server), Java development strategies for web apps (JUnit, true Java classes and inheritance, etc...) and browser neutral coding (the GWT compiler handles the various implementations of browser quirks). Your team focuses on writing code. Again, to mirror Chris's point, GWT is a web client based product, with a limited amount of server side niceness (but I'm a huge lover of GWTRPC so that makes my statement seem odd...but I digress). So you won't see any issues with hibernate, spring and spring security, because they are server side Java libraries. About the only issue is that you'll have to work with the GWT to Hibernate DTO...since it all ends up on client as Javascript. But what we've done is create pure Java value DTO's that are fully usable on client in GWT and fully usable on server in Hibernate...same exact classes, no cut and paste or tweeking. Try that with a Javascript client language. You mention PHP. GWT is compatible with PHP, mostly in the JSON area...because again, PHP is a server side language and GWT in this case would be your client side. I've seen that done a number of times... As for the dreaded reuse question: it is possible to take your compiled Javascript, which was created by GWT and maintain it. Sadly, I've seen it done. Once you do that, you can't go back. It's not unlike someone skilled back in the old days who would hand modify the compiled out Visual Basic project code and break what the VB IDE could do for them. But then I thought I had a good reason to do that The bottom line is that the resulting Javascript is fairly advanced and likely to be better than anything somebody would write on their own, but a hard core Javascript developer with mad spelunking skills and some time, could maintain the Javascript if you decided to walk away from GWT for some reason. All of the above opinions are expressly my own Later, Shaffer On Mar 9, 5:11 am, Chris Lercher cl_for_mail...@gmx.net wrote: Hi, I don't have an answer on the portal part of your question, but a few thoughts on the other parts: Are there limitations to using GWT, for example can you use, hibernate, spring, and spring security? GWT runs on the client (except for the parts from gwt-servlet.jar, which run on the server if you choose to use GWTRPC). So on the server, you can use whatever you want - this is not restricted by GWT. You just have to make sure, that GWT can handle the objects you transfer to the client - remember that everything used on the client has to be compiled to JavaScript, so it needs the source code for the entire object graph that is used. If you want to minimize these dependencies, you're probably best advised to use DTOs and keep the objects for the client simple. Is there a danger in locking ourselves into GWT for web based application development that we cannot move away from it? This depends on how much you rely on the Java to JavaScript magic (which won't be provided by a lot of other frameworks, I'm afraid). So if the complex parts of your application are either executed on the server side, or if they're written in JavaScript, you won't have much lock-in.

Re: GWT newbie have basic question to increase understanding ...
Fundamentally nothing has really changed. AJAX and therefore GWT is primarily a client side technology. What you've described are primarily server side. The major difference between an AJAX based web client and a traditional web client (like ASP, ASP.Net or even JSP) is how the information is pushed up to the server. In GWT-RPC, a client side proxy of a server based Java class is instantiated. When this is compiled into Javascript on the client this is translated into a client side XMLHTTP request, posting data to a specific server side servlet. If your server is not Java, then your options move to GWT Form Posting, which will end up looking very similar to the old ASP/ JSP form post servers, or there is a GWT-JSON method that allows submission of data to many brand servers using Javascript Object Notation. So to answer your question shorter: it depends on the technology stack that your server has. Good luck!

The first thing I noticed is that at one place in your message it's referred to as SelectionSearchServiceImp and in another it's SelectionSearchServiceImpl.

Re: Third party libraries for GWT
The two major UI libraries right now for GWT are Ext GWT and Smart GWT. There are some similarities and some differences. I've used both and they both allow for a look and feel on your GWT app that would take a lot of custom development to achieve. They both have some very nice widgets in both functionality and look. Ext GWT is a commercial, paid for library, Smart GWT is free and open source. I think that Ext GWT is a bit more stable, but neither is particularly unstable. The Smart GWT guys are also working on some interesting server side linkage to the UI components. Both have features that neither have. Being very attractive modern UI components, neither is light weight as they require a bunch of javascript and some nifty DOM manipulation (like all of the other Javascript UI libraries mind you!). So if your prospective client machines are a bunch of old Pentium III's running IE6 (my current burden!) then neither is particularily a good choice. In the end, I would score them as a tie. If your organization won't pay for their libraries, then Smart GWT is the only way to go. If your organization can't or won't use open source type of stuff, then Ext GWT is the way. Both require a lot of diligence and effort, as any good UI library does. But after a little learning curve, you'll be able to produce web UI's that are in a class equal to the richest heavy client.

Re: ServiceImpl and existing java app
If I'm understanding what you're attempting correctly, that's the easiest way to do it. Your ServiceImpl is still running in pure Java, and that's where an existing Java app can live. Your client will be compiled out into Javascript, so if you wanted your existing Java classes to be available on the client, the will be subject to the GWT compilation process. An amazing and powerful process, but it might yield references to Java libraries that are not compatible with the GWT Java/Javascript library. Good luck!

Re: compiling gwt with classes outside gwt jre emulation library
Without knowing your specifics, you have to evaluate what the additional class is doing. Perhaps there is a GWT compatible class that performs the same functionality. More than likely, what you want to do can't be done on the client. Remember: your GWT Java code is compiled into Javascript and run inside the browser container. That container has many rules that it must follow. And a lot of real basic feeling functionality (like writing to the file system for example) are not allowed. Your best bet is to take a look at the functionality that you using the java.net.HTTPURLConnection in, and see if that functionality can be replicated in GWT. That's about the best direction to go.

Re: Concerns about scalability and limitation in GWT
I can lob out this: on a previous project, not written in GWT but rather the old fashioned way with Javascript, we created a browser app (single HTML page, DOM managed in Javascript and XMLHTTP) that had about 250,000 lines of javascript. We deployed it to some fairly limited (read: old) machines in our call centers and did not have any significant issues relating to performance. We've written a number of smaller apps using GWT and are now in the process of replacing the old first generation app with a new one written in GWT, with significantly more features. We expect it to be very large and we are certain that the GWT compiler will produce tighter javascript code than I could ever write. Just my thoughts Good luck! Later, Shaffer On Jan 23, 5:46 pm, Shawn Pearce s...@google.com wrote: I'm not using GXT, but Gerrit2 (live demo at gerrit2.source.android.com) has its *.cache.html in the 368 KB ballpark, compressed with gzip -9 these deflate down to ~106 KB.

Everything you see is built and rendered in the client using the GWT widgets. The server only produces JSON for the client to parse and render as it wants to. Its not search engine friendly, but my point is, even with all of the functionality in the client, its still only 368 KB. GWT 1.6 will contain a feature to let you split up the application into smaller chunks and load on demand the JavaScript segments necessary for certain portions of the application. But that won't get you very much as most of your core widgets will still be in the initial download, and thus the initial download will still be pretty sizable. In Gerrit2 I plan on using this to segment out the administration screens and the user preference screens. These aren't accessed often and their code is very isolated, so taking them out of the initial download makes sense. But overall I don't expect a very large reduction on the initial download, as there is still quite a bit of shared code.

For GWT plugins there are really to choose from: Instantiations GWT Designer Cypal Studio Cypal is free where Instantiations is not (but is very reasonably priced @ $59). Instantiations value is that they provide a visual UI development tool, drag and drop controls onto a canvas and it generates the GWT UI code. Both also provide support for GWT-RPC and keep your server implementations matched with the client side as well as GWT-XML help. My team uses GWT Designer exclusively and it's great.

Re: What are you using for a backend??
Our primary dev targets are internal and therefore we control the servers...and use Java so GWT-RPC is beautiful. If doing it external and you just want a webhost, there are plenty that offer Java as an option. There are even more that offer PHP, like most everyone does. And then you would use JSON to communicate with your GWT app, not quite as slick as RPC, but still very usable.

Re: Need help with client server auth
The simplest thing I can comment is: that's about your only option. You've got various levels of security issues here, so I'm going to assume the simplest. You need the web client to be trusted by the GWT server (the server end of the GWT-RPC). Then you need the GWT server to be trusted by the application server. In most of our applications, we do server to server trust using Kerberos, service tickets and a whole bunch of authentication that is way beyond anything I want to write here. For GWT-RPC, we do a session id that contains the users Kerberos credentials ticket, which can be verified by a Spring inserted filter on our GWT RPC. We have done cookies in a SQL database, but today we've got code that takes the credentials and sends them to a cookie on the browser. That cookie is then visible to the server as it is included in the web request. We don't use SSL to harden our pipes, but we could and might. All of our users at this time are inside the firewall and we are therefore dealing with them via an LDAP (Microsoft Active Directory in our case). All of this sounds like mumbo jumbo no doubt. To do real security like we're doing, we've had a couple of us working on this for a couple of years. We've also done less secure security (oxymoronic perhaps) where we create a special session key and store it in SQL. We then send it down to the client where it is cookied. Every request has the cookie and our server side then extracts the session and validates against the session table in SQL. Then using the same session id, we can determine the users' credentials that we've also stuck in another table. This has allowed us to do things like certain users can't insert records or whatever rule you employ. But our security auditors haven't historically loved this and that's what prompted us to develop the Kerberos/service ticket solution. Now we are working with WS-Security to truly secure our SOA services...it never ends... Later, Shaffer On Jan 16, 3:58 am, Mikhail M itmo@gmail.com wrote: Need help!

Re: GWT and Business Intelligence.
You're asking an incredibly broad question that can only be answered - yes. My best advice to you is to start working with GWT and build yourself a prototype that will test some of your desired features. If your development team is proficient in Java, then GWT will be fairly easy. You'll need to understand the dynamics of AJAX browser development, and some understanding servlet containers, again this is a browser based web application...you do need to know some of the basics there. If you or your team has done anything like Swing, then GWT will feel very familiar, but browser based.

Re: can gwt work with javax.swing.* ?
OK, one of the things that you have to wrap your head around is how GWT works. You write GWT using Java, but then the GWT compiler converts this into Javascript HTML. It can only do this to Java that it specifically knows about. Your Swing JLabel component is not something GWT understands and therefore it can't compile it out into Javascript. The strength of GWT is that you develop in Java, but if your code is going to be run in the browser, it has to be Java that is compatible with the GWT Compiler. Hope this helps.

Re: GWT vs. Adobe Flex for UI development when J2EE/Spring is used for middle tier/server programming
Based upon your search criteria, it would seem that learning Flex is more marketable and therefore would be a better choice. However, if you are interested in creating solutions that are easier to code, easier to maintain and easier to integrate (when coming from a Java background), GWT is a better choice. That's not intended to sound illogical, that's the nature of the market today. Flex has a lot of buzz, always has. It's perceived as one of the sexy, highly styled UI web toolkits...and in the hands of an expert, you can create nice looking web UI's. But it is just a tool and in the hands of an amateur, equally amateurish results will follow. GWT suffers from two key points (IMHO). One, it's targeted at the Java developer. People like you. Boring, non-innovative Java developers who only know how to do servers and only get excited about connection pools and OR Maps (tongue in cheek here...) Java developers don't know how to create UI's and so a tool that allows the Java developer to create web UI's can't be good. The second point is related to the first. The hard core Javascript guys have been downtrodden and second-class citizens for years. Now with AJAX and the mature libraries that are out there, they've got some time in the spotlight. They're a scrappy bunch, that really know their stuff, and GWT threatens that existence. Surely GWT's compiler can't write Javascript as tight as minethat's the mentality. I speak from direct experience...I've written 100's of thousands of lines of Javascript. But if you're exposed to (or go back to your roots) a mature development environment, where real object oriented development patterns are primary, good design is key, but great maintainability, debuggability and team synergy due to language homogony is paramount, GWT because it's foundation is Java, is a killer. Flex is a bit of an anomally, it's not Javascript really, but it's not Java based either. When it comes down to what the choice is it's simple: is it valuable to your development process to have a second language stack in your solution? If your server side is Java, your client side is either Javascript or Flex (is it still called Actionscript, it's been a while). Or you write your server in Java AND your client in Java, and allow your compiler to optimize the client code to it's application container...that's what GWT does. Plain and simple. So if your criteria is job marketability and what you should learn, both are the wrong choice. Look for AJAX in the job descriptions, there will be zillions. They will require you to have deep domain knowledge of Javascript, along with CSS and HTML, plus a solid understand of JSON and the whole response/request methodology that XMLHTTP uses. You should also plan on getting very familiar with a number of the big libraries, like JQuery, YUI, Prototype, Scriptaculous, Rico, etc... You'll also need to know all the various ways that IE 6, IE 7 IE 8 are different than Firefox 2, 3 and Safari are different and how you code for all of these various browsers.

Re: Login security question
I can answer the 2nd the fastest. It does make sense to have Tomcat or whatever server handle things, until you have a multi-server cluster. Then typical session management ideals are tossed out the window.

How is that any different than getting the SID from the cookie on the server side? Theoretically if an attacker can replace the cookie, then wouldn't the GWT portion of the code that reads the cookie to send it along with the RPC request pick up the replaced cookie anyway? 2) What is wrong with simply relying on the normal Tomcat (et al) method of handling sessions? Perhaps I simply wish to store some information once the client has logged in via an authentication back- end that I do not control. Why do I need to send the SID along with each request?

You can also look at JSNI and the JavaScriptObject subclassing tricks in the

are more directly JavaScript entities, and thus more easily serialized with
JavaScript JSON libraries.

I tried wrapping the json2.js lib in a native method that calls
$wnd.JSON.stringify():
public abstract class JSONSerializer

public static final native String serialize(final Object object)/*-

}
but it pins my CPU and runs for several minutes when serializing
anything but a trivial object. The problem seemed to be the verbosity
(completeness?) of the object when marshalled across the Java-

mapping of Java properties to JSON ones.
Surely there's a better way? Or will I have to roll my own?

Re: how to set default button?
Maybe others with more GWT Form experience can chime in, but adding a KeyboardListener to your text boxes to do a form submit seems completely reasonable and non-hacky. In fact, it's completely in line with traditional UI paradigms, where the whole form submit() concept and all is what's really unusual. Another idea is to extend the FormPanel to something like MyCoolFormPanel and add your own .setDefaultButton method on it. Simply my random thoughts. Good luck!

Litty is correct, this is exactly how we are doing it in one of our applications. GWT-RPC between client and server, the server then manages the connection to a JMS queue.

Re: Does GWT RPC use HTTP?
And to follow up Suri's excellent description, I think it uses plain old port 80, but it is definitely just HTTP. You are just using a browser. If you want to be certain, fire up Wireshark (if you don't have this tool on your machine, shame on you!) and watch on port 80. Now that I'm typing it, I think you can configure Tomcat to use most any port. I think we were using 8080 for a while. But the bottom line is that it is just plain old HTTP. Later, Shaffer On Dec 7, 4:12 pm, Suri [EMAIL PROTECTED] wrote: Hi Venu, My understanding is that RPC is really a layer above the HTTP and if you notice how it works, its not unlike another servlet call.

Re: How to upload xml file with out writting servlet in the server side (using RPC call)
I believe the only way you're going to easily upload a file to a webserver is using servlets. You could move the XML content up to the server via an RPC call, and then on the server writing a new file to the server filesystem and stuffing the content into this new file. The problem that I can see is that if you want to have the user just point to a file on their local machine, you will have to do some serious magic to get that dragged into the web browser space. Again, fileupload and using servlets would be way easier in my opinion Why are you opposed to servlets, if I may be so bold to ask?

Re: Statement that GWT can be used to drive the UI of entire webapp is incomplete
But again I repeat: your beef is with AJAX as a whole. GWT doesn't make the issue you've described better or worse. It is endemic of all AJAX based technologies. That's my only point on the topic. On Dec 1, 2:24 pm, Pradeep [EMAIL PROTECTED] wrote: The thing is this - there are individual URLs and there are backend calls. You can browse to those URLs but you can't do a GET on them. Entire content is delivered in those backend calls in JSON which gets displayed by the web page. That's the content that should be indexed. Search engines won't make this association between URL and the backend calls, they want text. So for their benefit I have to dump those contents into an html page and thereby open a whole new pandora's box. That's the page they will oblige me by indexing and by directing users to. Then I do a redirect and send the users to a sensible web page. This is broken. I should never have attempted this. All this treachery about redirect/forward was what I wanted to get away from. But I couldn't. I didn't want to end up coding html and javascript by hand but now I have to. All over. From start to finish. This is not about optimization, this is about feasibility.

Re: Page navigation in GWT
The GWT (actually Ajax) way to look at navigation is not going from
one page to another, but rather staying on the same page and moving
your content in and out. Take a look at most samples and you'll see
something like
public void onModuleLoad() {
RootPanel.get().add(new MyCoolNewWidget());
}
where MyCoolNewWidget is something you've created that is your first
page. Perhaps on there is some widget that the user clicks to
navigate to the next page. It would look something like:
final Button moveMe = new Button(Next page);
moveMe.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
RootPanel.remove(0);
RootPanel.get().add(new AnotherReallyCoolWidget
());
}
});
In the click listener for the button, you first remove the content
from the RootPanel (basically the Window object in Javascript) and
then insert the new page in it's space.
The whole page based navigation methodology is really a web thing, any
heavy client, like those written in C# WinForms, SWT, Swing or MFC or
even OWL, you moved content in and out of the container which is
what the browser really becomes.
Later,
Shaffer

After a user logs in, I want them to be transported to a different

Where abouts should I be looking to edit? A new .html file? And if so,
what script should I include, as there is only 1 nocache.js file...

Re: GWT hosted mode in infinity loop when debugging
Without going into details, my advice is to first look at everything you added to your project since it stopped working. Speaking from personal experience, more than 99% of the time, it's something I've added that has caused the problem and not the vendor's. One other thing would be to create a new Debug... action in Eclipse. Can you build and run your project outside of Eclipse? Also try doing a Project/Clean Sometimes that helps. Back in the old days of Eclipse 3.1, we had to rebuild the project every once in a while but deleting the source from the project (not the file system) and reimporting.
