Plug in External Application to GWT
Hi, I am bit new to GWT and need guidance on following. I am trying to plug in external application (which is developed in different technology) to GWT. Is there any way I can call an external application from GWT and it will be displayed in one of the panel ? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: Migrating a GWT AppEngine App to a Chrome offline app
Ashwin - I am still considering various options. You have a point with offline clearing of cache. I would think that with offline storage like * IndexedDB* would not be deleted if the user clear the cache. At least the user will be prompted if an application data is going to be cleared. I am not sure how it works. My main point is I really do not want to invest in another technology for building a local app. I would want to use all the GWT code written so far. Also it should be easy to update chrome apps. This should simplify the distribution also. Also I think I would have to use hybrid approach of storing data in cloud. But I have the challenge of security. I would may be need to encrypt data using a key which only resides locally. There are lot of unknowns and I would have to figure out.

This maybe a good way to store data offline and probably sync to the server if your customer wants the data to be available online.

Re: Window.open() opens as a popup
Hi,
Directly call of Window.open() works perfectly to avoid popup blocker, but
I need to fetch URL with RPC call
onClick of the same button and open a new window, if I set global variable
to set URL and pass in Window.open() then it takes double click to open
newWindow, how can I achieve all with a single click of button?
thanks,
Vishal Dave

You have to make sure that you directly call Window.open() in the
ClickHandler. Don't to it in a Timer, deferred command or similar inside
the ClickHandler. The Browser must recognize that Window.open() is directly
called because of a user action. It does not matter if its a Button or an
Anchor.
Also don't do Window.open() somewhere deep in a sub function called inside
the ClickHandler.
Something like the following will work:
Button b = new Button(Test);
b.addClickHandler(new ClickHandler() {
void onClick(ClickEvent e) {
Window.open(http://www.google.de;, _blank, );
}
});
If you wrap Window.open() for example in a Timer it won't work anymore.

Need advise on how to organize my sample application.
Hi, I am writing a sample application to get to know GWT and GWT designer. This application requires user to login using Google account. It displays a list of customers and allows adding a customer. Can you please advise on how should I organize the UI? The I have organized the application: 1. I have used UserService for login purpose. 2. I have created 3 composites. Login, Home, Add customer. 3. I have added the composites to a deckpanel in the module with the entry point. 4. Created login service. 5. Created Customer service which handles add and get all customer functionality. When the application starts I check it checks if user is logged in. If not then the login composite is shown in the deckpanel. Once the user logs in the Home page is shown. On the home page the list of customers is shown. Now I click on the Add customer button in the Home composite. It takes me to the Add customer composite. I fill in the customer details and click Save button in the composite. How do I move to the Home page again without the composite knowing about the deckpanel? For now I have put the Save button outside the deck panel.

GWT form upload using BlobstoreService App Engine
I am using GWT and Google App Engine Java for my application. I have a profile screen where user enters profile information like name, age and address, saves it and gets success or failure message. I developed this initial application using GWT-RPC and it worked fine. I had a new requirement where I have to store image of the user. I am using BlobstoreService to store images. This has created complications in the flow. I had to use FormPanel as it is the only way to do a FileUpload in GWT. The BlobStore service servlet expects a redirect on completion. As a result it cannot now return any status back to my GWT application once the profile is saved. Is there easy to store images using GWT along with other form fields and show a status message back to user once the profile is saved. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

this initial application using GWT-RPC and it worked fine. I had a
new
requirement where I have to store image of the user. I am using
BlobstoreService to store images. This has created complications in
the flow. I had to use FormPanel as it is the only way to do a
FileUpload in GWT. The BlobStore service servlet expects a redirect
on
completion. As a result it cannot now return any status back to my
GWT
application once the profile is saved. Is there easy to store images
using GWT along with other form fields and show a status message back
to user once the profile is saved.

Cross Domain Scripting
I have an html page on a loaded on xxx.somedomain:301/some.html This html has script type=text/javascript language=javascript src=http:// yyy.somedomain:301/g-control/gwtc/z/z.nocache.js document.domain = 'somedomain:301'; /script and thus has to load up a GWT generated nocache.js. I have the add-linker name=xs/ added to the GWT.xml to allow Cross Domain Scripting. I am able to execute the nocache.js , but any RPC fail with com.google.gwt.http.client.RequestPermissionException: The URL http://yyy.somedomain:301/g-control/actionservice.foundation is invalid or violates the same-origin security restrictionCaused by: com.google.gwt.http.client.RequestException: What am I doing wrong here ? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Cross Domain Scripting
Thank u for the corrections and your response. To further clarify our problem domain. We want a Microsoft .NET based application to run our GWT app and and that server is on xxx.somedomain.com. To load up our GWT app , we wanted to source in the cache.js and subsequent data transfers through RPC from our java based tomcat server , in the same domain but on a different host yyy.somedomain.com. If I understood u correctly, the architecture that will bypass SOP would be * Create a Relay/Proxy on xxx.somedomain.com.. it is a IIS server and no servlets on that host. * The Relay as a relay should do , forwards the request ( any request ) to yyy.somedomain.com. * In the html src=http:// xxx.somedomain/g-control/gwtc/z/ z.nocache.js. This when loaded by the IIS server , actually relays the request to yyy.somedomain.com. * Any RPC executed on behalf of the downloaded js , will be to xxx.somedomain relayed to yyy.somedomain.com And thus we bypass SOP. Have I understood this correctly.. ( even though it seems I have just repeated your post ) and is it a well known practice top beat SOP ?

It just cannot work that way.You'd have to make requests to xxx.somedomain:301 (either hosting your RPC servlets on xxx.somedomain or setting up a proxy on xxx.somedomain to relay requests to yyy.somedomain); the xs linker only allows you to load the GWT app from another domain, but it doesn't bypass the Same-Origin Policy.

Re: Eclipse - debugging gwt app
I am also facing the same problem. The application does not stop at the break points.
