Re: How to do cross site implementation in GWT
Hi,
There is a bit change in approach. Somehow i am now able to connect to GWT
from my external HTML/website.
The way I have done is on click of a button in my html , I open a new window
which loads the GWT Host HTML which in turns calls a JSNI method.
The problem is now to pass some parameter from my website/HTML to GWT native
method.
Please help me out to get some way.
Thanking you for much needed help co-operation.
Regards
Manish

Subject: Re: How to do cross site implementation in GWT
One thing I just noticed in your code is that you are exporting java
methods to javascript. When I tryied that a few weeks ago I could not
figure out how the instance expression part worked, so I only have
tried this with static methods
e.g.
public static int displayDialog(String companyId, String companyName) {
ResponseDialog.getInstance().doSplash(companyId, companyName);
return 0;
}
public static native void exportJavaMethod() /*-{
$wnd.sendEmail =
@com.fbg.client.Emailer::displayDialog(Ljava/lang/String;Ljava/lang/String;);
}-*/;
and then calling the function from any javascript code in the host as
sendEmail(id, name)
Perhaps you can try changing PMGWTHtmlUtils::invokeGWT to be a static
function

/script
script type=text/javascript language=javascript

in the onModuleLoad() function I call the following native function to
read the javascript variables
public native void getParameters() /*-{
[EMAIL PROTECTED]::parameter_id =
$wnd.fbg_customerId;
[EMAIL PROTECTED]::parameter_format
= $wnd.fbg_type;
}-*/;
and after that I call the makeJSONRequest() function which is declared
as follows:
public static native void makeJSONRequest(String url, JSONHandler
handler) /*-{
$wnd.jsonCallback = function(jsonObj) {
@com.fbg.headlinesreader.client.HeadlinesReader::dispatchJSON(Lcom/google/gwt/core/client/JavaScriptObject;Lcom/fbg/headlinesreader/client/JSONHandler;)(jsonObj,
handler);
}
// create SCRIPT tag, and set SRC attribute equal to JSON
feed URL +
callback function name
var script = $wnd.document.createElement(script);
script.setAttribute(src, url+jsonCallback);
script.setAttribute(type, text/javascript);
$wnd.document.getElementsByTagName(head)[0].appendChild(script);
}-*/;
public static void dispatchJSON(JavaScriptObject jsonObj,
JSONHandler
handler) {
handler.handleJSON(jsonObj);
}
public void handleJSON(JavaScriptObject obj) {
// String s;
if (obj == null) {
// grr
return;
}
JSONArray myarr;
JSONObject myObj;
myarr = new JSONArray(obj);
for (int i=0; imyarr.size();i++) {
myObj = myarr.get(i).isObject();
headlines.add( new Headline(
myObj.get(title).isString().stringValue().trim(),
myObj.get(link).isString().stringValue().trim(),
myObj.get(create_date).isString().stringValue().trim()
) );
}
showNews(); //and this finally adds widgets to the
element
fbgPressReleases in the host page
}
I read that there was an inssue with firefox 3 and IE7 that made
difficult to access the window object of a webpage from a script
loaded from a different domain, so my Assumption is that the
add-linker name=xs / in the configuration signals GWT to work
around this issue

Hi Manuel,
Thanx for response.But I wanna know how do you passing the parameter

SecureRemoteService and Servlet. The battle against XSRF.
Hey everyone, I have been working a while now on properly defending my GWT app against Cross Site Request Forgery (XRSF) with a minimal change in the code of the application itself. My idea has been to create a new RPC call that will be the same from the programmers points of view as the normal, but which will add some value (a sessionID for instance) to the list of supplied parameters just before the call is send. Then, on the server side, the programmer would extend the SecureRemoteServiceSevlet (SRSS) instead of the normal one. This secure version will simply remove the extra paramater, check it's validity and only execute the requested method if the authentication succeeds. So far I have been able to subclass the RemoteServiceServlet (RSS) into the SRSS. It overrides the processCall(String payload) method to implement the verification (in my case the last argument, but that can easily be changed), thus working exactly the same as the normal RSS without any change needed in the code other than changing the extend. The problem is that I really do not understand where I might add the code to modify the sending of the request client side. I have studied the RPC diagrams and almost everything I could find on the group concerning RPC, but I still do not understand what I need to change or override to create a custom RPC call. I have thought about making a subclass of the ServiceDefTarget so that the calling URL could be modified, but this is an interface and not a class, so is not going to work. Does anyone have any idea's on this? Patrick PS: If I succeed at making something useful, I will create a package and a tutorial to share my knowledge.

Re: make my site visible to others
What do you mean with this question? It is a web page, this means that if you put it somewhere where other people can download it, they can see it. If you do not use fancy client-server connection things but only work client side, a free website hoster should do the trick. Look on your fav search engine to find a free webhoster and see their manual on how to upload files. Patrick On Nov 27, 11:41 pm, mskart [EMAIL PROTECTED] wrote: Hello everyone!

Re: SecureRemoteService and Servlet. The battle against XSRF.
Hi Patrick,
You could add parameters to the URL from an inner class inside the
RemoteService interface e.g.
public interface MyService extends RemoteService {
MyReturnValue aMethod();
/**
* Utility/Convinience class.
* Use MyService .App.getInstance() to access static instance of
IpsvRmapServiceAsync
*/
public static class App {
private static MyServiceAsync ourInstance = null;
public static synchronized MyServiceAsync getInstance() {
if (ourInstance == null) {
ourInstance = (MyServiceAsync ) GWT.create
(MyService.class);
// alter the URL here
((ServiceDefTarget) ourInstance).setServiceEntryPoint
(GWT.getModuleBaseURL() + MyService);
}
return ourInstance;
}
}
However that is probably not such a good idea 'cos the session ID
would be visible on the wire.
A second ideas is to use a variation of the Command pattern which
might better be called Payload since it doesn't execute() anything
itself on arrival. Something like
public abstract class Payload implements Serializable {
private String sessionID;
public Payload() {
sessionID = someSessionIDCookieGrabbingMethod();
}
// or alternatively
public Payload(String sessionID) {
this.sessionID = sessionID;
}
public String getSessionID {
return sessionID;
}
}
Then if you then extend this to make individual RPC service parameters
(a sort of bucket for the objects you need to pass over for each
service call (although sometimes they are reusable for several calls)
you can cast them all to Payload in your override processCall and
examine and validate the sessionID before processing the call.

Then to swap out:

That way you get the framework sort out the housekeeping for attaching

q.setMaxResults(request.getNumRows());
q.setFirstResult(request.getStartRow());
entityManager.getTransaction().commit();
result = new SerializableResponseCliente(q.getResultList());
System.out.println(I'm here);
return result;
}

DOM.setStyleAttribute questions
Recently I've found out that DOM.setStyleAttribute as well as getElement().getStyle() do not work for valid properties. At first I thought that it doesn't work at all but lately I found out that there are very few properties for which it works: Image image = new Image(images/someimage.gif); DOM.setStyleAttribute(image.getElement(), margin-left, 15px);// does nothing instead I found out that it works with DOM.setStyleAttribute(image.getElement(), marginLeft, 15px);// works DOM.setStyleAttribute(image.getElement(), coLLLor, red);//does nothing DOM.setStyleAttribute(image.getElement(), color, red);//does nothing DOM.setStyleAttribute(image.getElement(), color, rad);//throws Invalid property value. I found no documentation on such... let's say not evident behavior. Does anybody know why gwt developers changed margin-left to marginLeft? (I guess they use some BeanUtils for this stuff) why they throw exception on wrong property value but not on wrong property name? and why they do nothing when the property name is correct (like with color, yes, I know Image does not have such property).

One thing I just noticed in your code is that you are exporting java
methods to javascript. When I tryied that a few weeks ago I could not
figure out how the instance expression part worked, so I only have
tried this with static methods
e.g.
public static int displayDialog(String companyId, String companyName) {
ResponseDialog.getInstance().doSplash(companyId, companyName);
return 0;
}
public static native void exportJavaMethod() /*-{
$wnd.sendEmail =
@com.fbg.client.Emailer::displayDialog(Ljava/lang/String;Ljava/lang/String;);
}-*/;
and then calling the function from any javascript code in the host as
sendEmail(id, name)
Perhaps you can try changing PMGWTHtmlUtils::invokeGWT to be a static
function

with shortcuts.
public class PopupPanelWithKeyboardShortcuts extends PopupPanel {
private HashMapCharacter, Command keyCommandMap =
new HashMapCharacter, Command();
public PopupPanelWithKeyboardShortcuts(boolean autoHide) {
super(autoHide);
}
@Override
public boolean onKeyPressPreview(char key, int modifiers) {
Command command = keyCommandMap.get(key);
if (command != null) {
command.execute();

hide();
return super.onKeyPressPreview(key, modifiers);

Re: SmartGWT 1.0 Released
Debugging in Firebug is something that I'd like to avoid as much as I can. Especially for a GWT app which usually are pretty big. The nice thing about Ext-GWT is that I don't need to do that (probably once in the blue moon on a very extreme case). Knowing the internal Ext-GWT which is written in pure GWT also helps a lot. How about SmartGWT ? Do I need to know all the JS stuffs? Eventually I do if I want to do something more than the framework has to offer. I suppose one nice thing about wrapping JS is that you only deal with one low-level code-base. Other than that, I don't see any advantage. At the end of the day, I can only wish SmartGWT takes Ext-GWT approach. Last time I did a lame comparison on Ext-GWT and GWT-ext, Ext-GWT is much snappier compare to GWT-ext. I have couple questions though: 1) How do you guys do deferred binding in SmartGWT/SmartClient? 2) How do you optimize SmartClient for a specific browser? 3) How does the serialization work? if I recall last time, in GWT-ext someone has to purchase something else? On Nov 24, 10:56 am, ckendrick [EMAIL PROTECTED] wrote: Lest anyone get the wrong idea from francesco, when using SmartGWT you can debug your GWT *application* code normally within hosted mode. If you had a need to debug the core SmartClient libraries (normal users will not have a need to do this), you'd use debugging tools like Firebug and SmartClient's Developer Console. Calling this being out in the cold is bit of hyperbole given that SmartClient's very long track record of success has always been based on this approach, which works well, and will work even better with the next crop of browsers, *all* of which have Firebug clones. Finally, on performance - the real world performance of enterprise RIAs is dominated by the number of trips to the server and the intensity of database load. In this extremely key aspect - again the primary determinant of real-world performance - SmartClient/SmartGWT has a very dominant lead, which is due to it's sophisticated data binding architecture (particularly adaptive client-side operations and intelligent data caching). By comparison, possible code size differences caused by a different mix of JSNI vs Java code is at best a 3rd or 4th tier performance concern, and is frequently has literally zero impact on actual performance of delivered applications. Using JSNI has distinct advantages - as Sanjiv touched on, we are able to optimize things at a very low level within the SmartClient runtime, and we can more easily profile and tune core framework code because it's not going through a Java-JavaScript translator. This is very much like the mix of native C++ and higher level languages like C# within a .NET CLR - different languages for different tasks. Personally, for the kinds of applications that SmartGWT is designed for, I see it as a tremendous architectural advantage.

Smart Client is an amazing framework, but it is a JavScript framework. Using JSNI leaves you in the cold when you need to debug, as an example, but I am sure you know all that.

There are obviously several aspects to GWT that helps avoid leaks and such but this does not mean that any third party code written in GWT is 100% leak free. The GWT 1.6 event API is really neat andSmartGWTusers it. Well written code is what will perform well and display consistently across various browser.

For the most part it serializes just about anything GWT RPC would serialize, but the object property names appear plain text on the wire. The advantage of course is non-GWT clients and servers can actually speak to each other. Standard JSON along with automatic XSRF were my main requirements. The application I am using it in is open source, I don't want to be obfuscating the wire protocol.

Re: SecureRemoteService and Servlet. The battle against XSRF.
The solution is simple: Rewrite the session management part of your web stack so that it doesn't look at the cookie (it should completely ignore the cookie - it is there only to let the session survive when the user reloads the page / closes their browser), instead lifting the session out of the parameters. You don't need to remove it, really - any framework or servlet engine that gives unfettered access to the parameters also gives unfettered access to the cookies, so there's no point. gregor: What do you mean 'bad idea because the session ID would be visible on the wire'? All session IDs are visible on the wire, unless you set up a scheme where the client javascript does some hashing or encryption. It's been floated as an idea many times on this forum, and it is certainly feasible, but its very much outside of the norm. Virtually nobody on the entire web is doing this today. There are a number of issues I don't really want to get into. Suffice to say: Yes, doable. Yes, very cool. No, not standard or required by any stretch of the imagination. Such a scheme would still be significantly less secure than SSL, because it won't hold up to a man in the middle attack (the man in the middle will just modify your GWT code to send the password to his secret server in nigerussomania.

My idea has been to create a new RPC call that will be the same from the programmers points of view as the normal, but which will add some value (a sessionID for instance) to the list of supplied parameters just before the call is send. Then, on the server side, the programmer would extend the SecureRemoteServiceSevlet (SRSS) instead of the normal one. This secure version will simply remove the extra paramater, check it's validity and only execute the requested method if the authentication succeeds. So far I have been able to subclass the RemoteServiceServlet (RSS) into the SRSS. It overrides the processCall(String payload) method to implement the verification (in my case the last argument, but that can easily be changed), thus working exactly the same as the normal RSS without any change needed in the code other than changing the extend. The problem is that I really do not understand where I might add the code to modify the sending of the request client side. I have studied the RPC diagrams and almost everything I could find on the group concerning RPC, but I still do not understand what I need to change or override to create a custom RPC call.

Re: SecureRemoteService and Servlet. The battle against XSRF.
@Reinier gregor: What do you mean 'bad idea because the session ID would be visible on the wire'? All session IDs are visible on the wire, unless you set up a scheme where the client javascript does some hashing or encryption. Suppose I replaced: sessionID = someSessionIDCookieGrabbingMethod(); with: sessionID = someReinierApprovedEncryptionAlgorithm(); would this meet with your approval? If not can you explain why? regards gregor It's been floated as an idea many times on this forum, and it is certainly feasible, but its very much outside of the norm. Virtually nobody on the entire web is doing this today. There are a number of issues I don't really want to get into. Suffice to say: Yes, doable. Yes, very cool. No, not standard or required by any stretch of the imagination. Such a scheme would still be significantly less secure than SSL, because it won't hold up to a man in the middle attack (the man in the middle will just modify your GWT code to send the password to his secret server in nigerussomania.

My idea has been to create a new RPC call that will be the same from the programmers points of view as the normal, but which will add some value (a sessionID for instance) to the list of supplied parameters just before the call is send. Then, on the server side, the programmer would extend the SecureRemoteServiceSevlet (SRSS) instead of the normal one. This secure version will simply remove the extra paramater, check it's validity and only execute the requested method if the authentication succeeds. So far I have been able to subclass the RemoteServiceServlet (RSS) into the SRSS. It overrides the processCall(String payload) method to implement the verification (in my case the last argument, but that can easily be changed), thus working exactly the same as the normal RSS without any change needed in the code other than changing the extend. The problem is that I really do not understand where I might add the code to modify the sending of the request client side. I have studied the RPC diagrams and almost everything I could find on the group concerning RPC, but I still do not understand what I need to change or override to create a custom RPC call.

Re: Deploying servlets
Hi I am using GWT.getModuleBaseURL(), so I changed my Clod.gwt.xml file, and ive managed to get the RPC services to error now, because it is looking for /Cloud//RPCService. Ive tried getting the 'Service doesnt accept GET' message (when you try to access a sevice directly), but I cant find it now. Ive tried: /Cloud/RPCService /com.cloud.Cloud/RPCService /com/cloud/Cloud/RPCService /RPCService None of these get me the message, so im not sure how to configure my xml file, as I dont know where the service is now mapped to. I am using this line: target.setServiceEntryPoint(GWT.getModuleBaseURL() + /RPCService); and the corespoinding line in my .gwt.xml file: servlet path=/RPCService class=com.cloud.server.RPCServiceImpl / Should I change the servlet-path?

URL listener?
Hi guys! It is nice to alter the url with the content so we can always come back by just accessing the url. I'm sure you know that to do this without actually reloading the page you can append #parameters. For example changing from http://mypage.com/product#id=4 to http://mypage.com/product#id=53 would not reload the page because it's basically the same, but can show different content by parsing the id parameter from the url. My question is if there's a way to listen to a URL change? The only think I've come up till now is to periodically check for a change in the url, but that's always a bad move. Any ideas? Thanks!

XML to UI Forms
Hi, Maybe, I am too lazy but is there a way for gwt to convert whats in XML (formatted according to gwt requirements) which can parse and construct the form and allow the users to edit and once done, saves to the xml again for future processing. I am trying to avoid learning GWT specific UI elements and gain control from some wrappers which load from xml and save to xml. Something close would be http://extjs.com/examples/grid/editable.html http://extjs.com/examples/forms/advanced.html but they should be read from xml and built upon. Sure, I can write the wrappers but I was checking if someone has done this before. A UI-xml framework?

Re: Pass an applicationSessionId in each rpc request
You could just change the request urls: target.setServiceEntryPoint(GWT.getModuleBaseURL() + / + service +;sessionid=+sessionId); I haven't tried it, but assume it would work. You would have to pull out the appropriate information on the server side. Joe On Nov 28, 5:35 am, seb2nim [EMAIL PROTECTED] wrote: Hi everyone.

Drawback is that once passed to client-side code, i need to pass it on every rpc call... and i'm a lazy guy... I dont want to refactor each method signature... As RPC mecanism is now improved in GWT1.5 : The first is that asynchronous interface methods can now return the underlying HTTP request object (http.client.Request) so you can access and tweak it as necessary for your application needs before sending it off through RPC. Asynchronous interface methods can now also return void or http.client.RequestBuilder objects. I think i can tweak my calls to append the appSessId in header or something like that.

File download using GWT?
Here's a tricky one for you GWT experts! In my application, I need to dynamically create a text file (in memory) and allow the user to download it. In a traditional web application, this is easy. However, how can you do this with GWT? Before you answer, keep in mind that the file does not exist on disk anywhere. Therefore, a GWT-RPC service would send a String back to the GWT client and the client would have to do something to trigger the download of that string as a file. I have already searched this forum and there is a thread on doing a file download but that's for a file that exists on disk and for various reasons, my application cannot write the string to a file first. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Timer In Gwt
Hi Guys,
I am Working On A Screen Where i Need to Display some Error Message
and Some Success Messages.What i did is i created my own widget of
some Label type . when ever i need to show a message i would set the
text to label and display it on the top of the screen much like gmail.
the issue i added a timer for the label so that it disappears
automatically after some time.
i have written the code like this,
Timer t = new Timer() {
public void run() {
header.setErrorMessage(Error Message);
header.setVisible(true);
setWidget(0, 1, header);
}
};
t.schedule(500);
header is my label type of element. i was displaying some 30 types of
different message. so my timer code has increased a lot . can any one
suggest me how to use a single timer class for all.

TextArea cannot be resolved to a type
Hello. I have just begun learning java (about 2 months ago) and am now trying to develop a couple applications for the web using java and the GWT. I am having some difficulty and hoping someone can help me out. My first problem I am having is I am getting this error message TextArea cannot be resolved to a type when I am trying to create a text area. I get the error message twice, and for the same line in my code which is TextArea ta = new TextArea(); Is there a line (or multiple lines) of code I have to implement before I can implement the TextArea object? Also, I need to allow the user to paste some information into this text box and allow me to store that information in a variable, and then do something with the information, and then output some information to the user (even in the same text box is fine). Can some one please help me get started on this? Finally, I was wondering if the GWT supports reading the HTML file of a URL, which would normally be done by something like this: URL results = new URL(http://www.some-url.com;); BufferedReader in2 = new BufferedReader( new InputStreamReader( results.openStream())); String inputLine = in2.readLine(); Thank you very much. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: gen2 tables: Create TableDefinition based on annotations
Uuups, only working in hosted mode :-(

Hi,
I've used that Generator stuff in gwt for the first time and I've to
admit that it is really cool!
I've been using it to simplify the creation of model based gen2-
tables. Instead of defining the TableDefinition programmatically you
now have the alternative to do it with annotations in your domain
class.
Example:
public static class Ancestor extends AbstractTreeTableItem implements
RowValue {
private String firstName, lastName;
private double iq;
private Date dateOfBirth;
public Ancestor(String firstName, String lastName, int iq, Date
dateOfBirth) {
this.firstName = firstName;
this.lastName = lastName;
this.iq = iq;
this.dateOfBirth = dateOfBirth;
}
@ColumnDefinition(column = 0, header = First name, filterable =
false)
public String getFirstName() {
return firstName;
}
@ColumnDefinition(column = 1, header = Last name)
public String getLastName() {
return lastName;
}
@ColumnDefinition(column = 2, header = IQ, numberFormat =
NumberColumnFormat.SCIENTIFIC_FORMAT)
public double getIq() {
return iq;
}
@ColumnDefinition(column = 3, header = Date of birth,
dateTimeFormat = DateColumnFormat.SHORT_DATE_FORMAT)
public Date getDateOfBirth() {
return dateOfBirth;
}
@Override
public String getDisplayName() {
return firstName + + lastName;
}
@Override
public String getId() {
return firstName + lastName + dateOfBirth;
}
}
Note that you have to implement the RowValue marker interface. Now you
are ready to create your TableDefinition like this:
TableDefinitionAncestor tableDefinition = GWT.create
(Ancestor.class);
Very cool! Thanks for this brilliant toolkit!!
