Re: RequestBuilder, safely send data to server
Seconded. One of the best bits of advise I ever got is, "if you have a validation on the client, re-validate on the server". The JSR validation makes it easy to be sure validation is consistent, but I've not tried it now that the validation is a library.

Re: GWT RPC in GWT 3.0+

Re: How to make my app more secure. URL token
Your GUI needs a check, then. I handle this by having every Place (and even some sub-forms) check for a user on display and display a logged out UI if there is no current valid user. Of course, I'm using a login dialog instead of a Place, so if someone's session times out they can re-authenticate without losing any data...

Re: Getting username from url only works after refresh
For some reason, passing the username around via the URL seems like a code
smell to me.
I'm not sure if it's actually better or not, but I store the User object
from the server (less password hash) in a singleton (and the session, in
case of a full refresh). I also have all my Place content setup so I just
change it within a Panel (TabLayoutPanel, though Dock or Stack would work,
too) while leaving navigation and header alone.
This removes putting user information in the URL, so people can share
deep-links to content without sharing usernames by default.

Re: Why can I not extend java.util.Date?
If you do extend Date, I would not use any 3rd party library calls that
take a Date and may use Day of Week, as they might well explode on Sundays.
And that has the same problem as a util class, you may forget and make the
call somewhere. It's really a lose-lose situation.
You're not really saying what you're doing with the ISO DOW, but you do
know that SimpleDateFormat supports the ISO enumeration, right? Looks like
"u" is the Monday = 1, Sunday = 7 version, though "F" may also work.
As for the Java 8 java.time support, it appears it is planned but not yet
in-progress: https://github.com/gwtproject/gwt/issues/611

Re: Third Party Library for GWT validation
So you never convert the JSON to a POJO client side? (GWT responses use
GSON, a Google-modified JSON, and are converted to POJO post-receive.)
My best suggestion then is to just walk the JSON as a Map and use a custom
validator interface...

Are you not marshalling the response into a POJO? GWT Validation can be

Chrome prompts me to install GWT Developer Plugin even though the plugin is already installed
I've been working with this plugin, using Dev Mode Classic for several weeks without issues. All of a sudden, this morning, it now continually prompts me to install the plugin, even though it already has been. I have rebooted, uninstalled/re-installed first the plugin, then Chrome itself. Is it possible a recent plugin update broke the plugin? Does anyone have any ideas?

Re: Unable to use memcacheservice in gwt module
Not directly. You'll have to write a service/servlet to provide Memcache access to the client. Alternately, HashMap can be used in GWT as a Cache, as can some of the Guava Caches.

Re: Unable to use memcacheservice in gwt module
The problem is that you've put server-side code in your GWT. Whatever is asking for the memcache needs to be moved out of your client or shared packages.

Re: GWT + GAE : how to handle communication failure...
Reduce the size of SaveBarterItemResult. If the whole 3MB of data is
required, but causes disconnects frequently, return a smaller/lighter
object from the save call, and then retrieve the full data set in a more
resilient manner.

Hello.
I have a question concerning: how to handle communication failure...
The best way to explain my problem is to give an exemple:
In my app, the user has a gwt UI page where he creates an item when he
has finished to fill all the requested information, he clics on a save
button which is going to call the server using RPC:
serverService.saveBarterItem(saveItemRequest, new
AsyncCallbackSaveBarterItemResult() {
public void onSuccess(SaveBarterItemResult result) {}
public void onFailure(Throwable caught) {}
});
in my exemple, when everything is going ok, the server returns an object
SaveBarterItemResult.
imagine that the object that should be returned is very big in size (for
exemple 3 MB).
NOW imagine the following scenario:
the client (the browser of the user) successfully reach the server.
the server (which is a GAE) save the item in the DB and starts returning
the result.
then the internet of the client is lost
--
the onFailure function is called in the browser...
which makes the user think that the item has not been send
successfully... (whereas in fact it has been send successfully and it has
also been saved successfully)
THE PROBLEM THAT I HAVE is that I have no way to know that the item has
been saved successfully on the server.
(so the normal way for my gwt app to behave would be to let the user click
on the save button again... but if he does, then his item will be saved two
times...)

Re: Load/Display KML file in GWT Google Maps
Irene,
I don't have a tutorial for you, but it is rather simple and
straightforward. The process goes like this:
pre
GeoXmlOverlay.load(key, new GeoXmlLoadCallback() {
@Override
public void onSuccess(String url, GeoXmlOverlay overlay) {
map.addOverlay(overlay);
overlay.gotoDefaultViewport(map);
}
@Override
public void onFailure(String url, Throwable caught) {
Window.alert(Retrieving data for the overlay caused the
+
following error:\n\n + caught.getMessage());
}
});
/pre
It's a simple call to the static load method of GeoXmlOverlay. It
takes the url of the KML/KMZ file (must be a public location) and a
callback. The callback will contain an actual GeoXmlOverlay object
that can be added to your map via addOverlay. It also has a method
that lets you recenter the map to the overlay itself so in the example
above, I add the overlay to the map and then make sure the new overlay
is visible to the user.

Re: Manipulate localized date on the server side
Sydney,
I don't know if it's the best approach or not, but keep all dates and
times in GMT on the server side. I simply add or subtract the local
offset on the client. In places where the user enters a date/time, I
offset it to GMT before passing it to the server. The conversion is
very fast and I never have to worry about any conversions on the
server side. I do the conversion on the client only when I want to
show it in the local time zone (which is all the time at this point).
For reports/exports, I let the user choose to export the data in their
local time or GMT.

locale en-US: November 1, December 0
locale fr-FR: Novembre 0, Decembre 1
1/ I understand that to use this algorithm it needs to be executed on the
server side, but the method is part of an object Facility that can be shared
client and server side. Where should I put this method to be able to run it
on the server side? Also this version does not use any locale, so how can I
get the client locale?
2/ Another solution is to return the list of date and run the algorithm on
the client side by using DateTimeFormat but I am wondering if it's a good
solution since you have to send a lot of data over the wire.

Re: Get a PDF from the Server
Sean, The way I do it (and this may not be the best way) is to use RPC to send the user requests to the server. Then, I store the request data in a table on the server, generating a unique id for that data. The unique id is returned to the user via the RPC callback. Then, a new window is opened with the url set to the servlet address and the unique id as the token in the url. In the servlet, I use that token to look up the request data, build the PDF, delete the request data, and return the PDF. This method allows me to send as much data as I want via RPC and then I only need to send a single parameter with the url to the servlet.

Re: Deploying GWT project on Tomcat
After you compile your project, go into the war folder and zip up the contents of that folder. Name the zip file something.war where something will be what you want your url to be.

Re: Handling ClickEvents with custom composite widgets
nathan, When building composite widgets, it is up to you, within the composite widget, to handle and/or expose whatever events you want. So, if you want to be able to expose click events for multiple buttons in a composite, you may be best off doing one of two things: 1) Create a public enum that contains an entry for each of the buttons. Then, provide a method to get which button was clicked so that when someone handles the click event, they can query for the most recently clicked button. 2) Create custom events for each action that can be taken by the composite widget and you other classes would handle those custom events rather than a click event. Option 2 is better, but more complicated. Generally, when you create a composite widget, the internal widgets are all handled by the composite. If you want access to all the internals, then you aren't really wanting a composite widget at all.

Re: Route animation in google maps with GWT
Jan, You can do it all with GWT. You can see a partial example of it here: http://www.dtrac.us/hmr.html I say partial because that page is setup for a race that takes place in the future so there aren't any position reports to show yet. But, even without that, you can see how the time line and animation works. There is a time line (slider control) that can be manipulated manually. There is a spinner control to allow user control over the speed (forwards and backwards). There are also overlays that can be turned on and off (and zoomed into). And the main race course can be zoomed to (target images). We will also be tracking Marco Nannini in the Route du Rhum next month. You can see the tracking page for his race on his site: http://www.marconannini.com/tracking You'll notice the sites look very similar. The fact is, I did this data driven. This way, I can just add a few rows to a few tables to create a new event. It also supports multiple devices (boats, cars, people, whatever) in a single event. It's not hard to do. Brian pretty much hit it on the head when he said to use an array and a timer. Mine was a little more complex since I keep the slider, the polyline, and the position reports all in sync.

Re: Sending mails from GWT-App
He meant it isn't a GWT issue. The code you are trying to make work
has nothing to do with GWT other than it is being referenced from the
server-side code compiled by your GWT app. That said, here's some code
I use to send emails:
pre
try {
Session mailSession =
Session.getDefaultInstance(getProperties(hostRow));
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
String body = emailRow.getBodyText();
message.setSubject(emailRow.getTheme());
message.setContent(body, text/plain);
message.addRecipient(RecipientType.TO,
new InternetAddress(userRow.getEmail()));
transport.connect(hostRow.getHostName(), hostRow.getHostPort(),
hostRow.getAuthUser(), hostRow.getAuthPass());
transport.sendMessage(message,
message.getRecipients(RecipientType.TO));
transport.close();
} catch (Throwable caught) {
throw new Exception(caught.getMessage());
}

I was wondering why I do not have to enter a password for the smtp-

Smtp-Host at props.put() again ...
Thanks!

Re: Crop a photo stored locally
Josh, If I were doing it, I think I'd start off with a route something like this: - User uploads photo - Servlet saves the photo somewhere (database or file system) - Client page displays the image (using Image widget) - User can drag and drop to create a cropping rectangle over the image - When user is done, use RPC to send the size and location (relative to the Image widget) to the server - Server side code crops the image based on that size and location and saves to database or file system HTH, Chad On Sep 22, 10:02 pm, Josh Tinkham unitin...@gmail.com wrote: I'm building a costume database program for a local high school.

Re: How to add a widget as a Panel on top of the MapPanel
Kiarash, What are you trying to accomplish? You want to cover the map with a panel, but still have the map work? If the panel contains an image that you are simply trying to overlay on the map, use the map.addOverlay method. With that, you can put images or just about anything else you want right on the map and it becomes part of the map so that the map keeps all of its functionality. If that's not what you're after, please try to explain what you want a bit more clearly.

Re: Returning values, next try. Sending was too fast for me
When you call loginUser, you will create an instance of
XGENgwtModelCallback (I'm assuming that's what you called
LoginCallback). In that instantiation, you will need to define the
onLogin method:
loginModel.loginUser(user, passwd, false, new XGENgwtModelCallback() {
@Override
public void onLogin(int feedback) {
// Decide what to do using the feedback parameter which contains
your value
});
If you want to use the same interface for multiple callback types, you
can add methods, but then you'll have to implement them in every case.
So, you will end up implementing methods that won't get called. It's
better to create a specific interface for each type of callback you
need.

Chad

I'm using gwt-mvc. So, the described Method is located in the Model.
What to do in the Controller exactly? After calling loginUser, my
program decides which way to go by taking the feedback.
So should I do the following?
loginModel.loginUser(user, passwd, false, new XGENgwtModelCallback(
/* Decide what to do, but how to get the loginFeedback */
));
Thinking Async almost drives my crazy :-(
BTW: I've got other methods, which return DB2-SQL-Queries as a

ModelCallback and add another Method public void
onSQLQuery(VectorVectorString vec) as well, should I?

Learning to develop Custom Widgets :: onAttach
I am working on developing a few custom widgets in order to learn how GWT works. One of these widgets is a custom scrollbar similar to that used by Google Wave. I have most of the widget working using nested DIV elements to display the visual elements. However, I am having difficulty getting the controls Up Button, Down Button and the Drag handle to provide events to my widget instance. These elements were created using nested DIVs as well. This scrollbar is not nested in a parent widget, but scrollbar itself is attached to the root of the DOM and is positioned dynamically. I cannot receive the events on the nested DIV elements unless I call the onAttach method in my constructor.

Re: How to put same widget under multiple tabs in TabLayoutPanel?
One option would be to add a selection handler to the TabPanel and
when the tab changes remove the controls from the display and attach
them to the new tabs content.

theming CssResourse and ClientBundle
I am working on creating a number of custom widgets and would like to enable the user of my modules jar to customize the appearance of these widgets. In the process of creating the widgets I have used a ClientBundle to hold the ImageResources and an embedded CssResource. Is it possible for the end user to override style properties and/or provide alternate images for these widgets? What is the best practice for creating a theme-able widget library?

Re: load content of directory server side Options
On the server, you can use Java (or whatever else you want). So, make
an RPC call from the client to the server to get the file names. You
could return a string array. On the server, it could be as easy as:
public String[] getImageNames() {
return new File('images').list();
}
Obviously, you would want to throw in some error checking and such.

Can you define the images using a client bundle? See

if i understand it right
using the above i have to manually define all the images
i would prefer reading the content of the directory 'on the fly'
there can be a lot of images

Re: Multi-tenancy in GWT
Kyle, While you *may* be able to do that, the general GWT way would be to have your urls look more like this: mysite.com/myapp.html#/acmeHairSalon mysite.com/myapp.html#/genericDogCollars And you can easily access the tokens via the History class (the getToken method).

Both URLs should map to the same instance of the application but in it, I'd check the URL to see which company was being used and filter all the data in it accordingly. I know how to do the filtering and can probably figure out how to check the URL for a company token.

Earth Map won't load
Hi all,
I have an app that has been working fine (in development and on the
web) with the map integrated. Now, I want to add the Google Earth plug-
in as a map type. When I first added the code to set the current map
type to the earth map, it didn't work in Chrome, but it did work in IE
and FF. This was in development only. Then, it stopped working in all
browsers. I would just the the page that says my key isn't right.
After searching the web, I found that this is a generic error message
and not representative of the actual error that is likely occurring.
My map setup code is as follows:
private void setupMap() {
map = new MapWidget();
map.setStyleName(mm-Map);
map.getEarthInstance(this);
map.addMapType(MapType.getPhysicalMap());
map.addMapType(MapType.getEarthMap());
setInitialMapType();
map.setScrollWheelZoomEnabled(true);
map.addControl(new LargeMapControl3D());
map.addControl(new MenuMapTypeControl());
map.addMapClickHandler(this);
map.addMapMouseMoveHandler(this);
map.addMapMouseOutHandler(this);
map.addMapTypeChangedHandler(this);
}
At first, I didn't have the getEarthInstance call, but I added it
trying to get it to work. Right now, when the callback from
getEarthInstance fails, I remove the earth map type from the map to
keep users from seeing the error page.
What should I have to do to be able to have the earth view in the map?
TIA,
Chad

GWT RPC behind an Apache Proxy

Re: NT User name
Ben, You can use NTLM, LDAP, or Kerberos for that. The easiest (for both you and your users) is NTLM. You'll want to use the Jespa library (http://www.ioplex.com/). I am not affiliated with them in any way, but I do use the product. With that, all you need to do is add some settings to your web.xml file and you will be able to get the username from your server-side code. Everything you will need is in their documentation and they have a 60-day trial. After that it is limited to 25 users. If you have 25 or fewer users, you can use their product for free.

Jie,
Subclass the StackPanel and override the showStack method:
@Override

You could also add more methods to allow adding handlers/listeners if
you want.

Re: Panel whose which can expand past the dimensions of the screen
Perhaps a different approach may work better (and more efficiently). What if you only add the child widgets that were visible (or maybe one or two extra)? Then, as you press the buttons to scroll, just add and remove the child widgets as needed. You could probably do that with a single panel instead of two. You could keep a List of child widgets. Keep an index of the one in focus and load and unload as needed. Otherwise, I suspect you will need to add the getOffsetWidth of each child plus the width of whatever margin you have between each and set the inner panel size directly. It sounds like you already tried that, but I'm not sure why it wouldn't be an exact thing for you.

The problem is this: Upon populating the HorizontalPanel, it will expand up to a certain width, maybe 1200-1300px, then it will stop and squish together and clip the child widgets. I can sort of solve the problem by dynamically increasing the width based on the width of each child but this is inexact and looks bad. Is there a certain type of panel I can use which can automatically resize itself beyond the 1200px-1300px limit?

Re: question from a novice in GWT
@nyankov: Simple, really. Leave your current (non-GWT) site intact. Then, create a separate application (GWT) with a vertical panel containing a frame and the toolbar. Disable the window scroll bars. Add a window resize handler to keep your vertical panel sized full page (or maybe just set the vertical panel height and width to 100%). Make sure the toolbar height is set absolutely. Set the url of your frame to that of your original site (relative path should work being on the same server). The frame will have scroll bars if needed. That should do it, I think. If you don't like that idea, you could always use frame sets (yuck) and create two frames (vertically). Just put your current site in the top frame and your GWT site (toolbar) in the bottom frame. Assuming you want to change pages via the toolbar, you'd be better off with the solution above over frame set. @Ian: I think that's what the OP was doing originally, but was unhappy with the jumpiness on scrolling and resizing.

Re: how to determine when StackPanel index changes?
Phineas Gage,
I haven't tried it, but you could probably override either the
showStack or onBrowserEvent method. Probably showStack, something like
this:
@Override
public void showStack(int index) {
super.showStack(index);
if (index == getSelectedIndex()) {
onShowStack();
}
}
And, of course, create an onShowStack method that would only be called
when the stack is changed.
HTH,
Chad

When using a StackPanel, is there any way to listen for when the

I see that it can be retrieved with getSelectedIndex() and set with
showStack(index), but there is no apparent way to be called when
someone clicks to set the current index. I'd like to do this so that I
can set a history token and restore the StackPanel to its original
state when the back button is pressed or an external link is used...

David, You don't have to do all that. Just reference your images as: images/status.png Notice the lack of the slash before images. If your images folder is in your war folder, it should work in both hosted mode and web mode. That slash would force a non-relative path requiring you to go through the extra hoops you found.

Re: Refresh page on loading
Rahul,
Instead of trying to refresh the page, you should probably defer the
loading of your buttons, labels, and tabs. Use a DeferredCommand for
making the call to the method(s) for creating those widgets. It sounds
like they are loading before something that they rely on loads.
Although, this may have no effect whatsoever. :-/

First problem is that you are asking a JavaScript question in a GWT

:-)
Second problem is that your webpage will loop, endlessly loading and
reloading. This a pretty basic a mistake, so maybe it would be a good
idea
to search for some JavaScript tutorials or sign up to a JavaScript

Re: Displaying a loading image while waiting on RPC
Nick,
Obviously, that works, too. You can also show/hide your image with the
RootPanel instead of the DOM class (I don't know which would be better
-- someone else may be able to chime in on that) by doing:
RootPanel.get(ajaxloader).setVisible(true); // or false as needed
I just took a look at your site. I like it. You may want to fetch
listings on map resizing as well. If you zoom out, you still have to
move the map before listings load into view. Zooming in wouldn't be a
problem. Overall, I think it's very nice.
Good work,
Chad

Thanks! You got me on the right track. I ended up embedding an

I put the following at the beginning of my onModuleLoad():
final Element ajaxloader = DOM.getElementById(ajaxloader);
DOM.setStyleAttribute(ajaxloader, display, none);
(where ajaxloader is the id of the loading icon in my HTML file)
and then, as you two suggested, I exposed the icon at the beginning of
my click handler (in my case, calling DOM.setStyleAttribute
(ajaxloader, display, block);) before doing the RPC and then hid
it in both the onSuccess() and onFailure() of my AsyncCallback (in my
case, by calling DOM.setStyleAttribute(ajaxloader, display,
none);). The result can be seen at nicksmap.org (still very much a

Re: Changing a GWT css default
Charlie, Look in the GWT SDK in your project. Look into com.google.gwt.user.theme.standard (or dark or chrome if you are using those instead). Drill down into the public/gwt/standard folders and you will find the standard.css. You can open it and find the gwt- DialogBox css classes that are used for the dialog box. Copy all of those classes into your project's css file and replace all of the gwt- DialogBox with whatever you want to call them (gwt-DialogBoxCustom or charlie-DialogBox or whatever). Make sure you only replace the primary style name, not the dependent style names. Then, make the few little changes you need. In your code, call setStylePrimaryName(charlie- DialogBox) on your custom dialog box. That should get you what you want.

So, for the caption style class, it has this:
.gwt-DialogBox .Caption {
background: #e3e8f3 url(images/hborder.png) repeat-x 0px -2003px;
padding: 4px 4px 4px 8px;
cursor: default;
border-bottom: 1px solid #bb;
border-top: 5px solid #d0e4f6;
}
If you want to call your class styling my-DialogBox, you would change
the above to this:
.my-DialogBox .Caption {
background: #e3e8f3 url(images/hborder.png) repeat-x 0px -2003px;
padding: 4px 4px 4px 8px;
cursor: default;
border-bottom: 1px solid #bb;
border-top: 5px solid #d0e4f6;
}
Notice, I only changed the primary style name (gwt-DialogBox), not the
dependent style name (Caption). So, once you have the entire section
of the css copied into your css file, you should be able to do a Find/
Replace on gwt-DialogBox with whatever you want to call it. Again, you
would only need to do this if you wanted to use both the default GWT
styling on some controls and custom styling on other controls (which
is what you are wanting).
What you may want to do is copy the needed css into your project's css
file, do the Find/Replace on the primary style class name, then test
your app. It should look just like the default dialog box at this
point since it's an exact copy. Then, make your changes to your css
file and test again to see the changes reflected.

Look in the GWT SDK in your project. Look into

Re: Modelling framework
Kaspar, While you probably can find the kind of tool you are looking for (I don't know of any since I don't have a need for them), I would question your data design. You should be able to design your data so that users can add questions without changing the data structure, just the data content. Then, you can build your app with a set data structure, but the data can be completely dynamic. This would result in the same experience for the user, but a lot less work for you and most likely less fragility for your data.

Re: Export GWT app as WAR file - EASY tutorial for this?
Martin, It can depend on your version of GWT. If you are using the GWT-Eclipse Plugin (GEP), you can just click the GWT Compile button from the toolbar. After it compiles successfully, open your project folder (outside of Eclipse). You will see a war folder inside your project folder. Open that war folder. You will see a few files and folders. Select everything and create a zip file (this should be a right-click action). Name the zip file something.war and that's it. When you drop that war file into your Tomcat webapps folder, it will get automatically expanded into a folder named the same as the war file name (without the extension). If you are using an older version of GWT, then the manual steps I outlined a while back may help and can be found: http://milamade.com/code/gwt/createwar.htm HTH, Chad On Jul 20, 8:01 am, martinhansen martin.hanse...@googlemail.com wrote: Hi, I want to export my GWT app as a WAR file and deploy it on a tomcat server.

Re: Copying from Result Set to Array List
Rahul,
Based on your query (select SourceTableName from SourceTables), I
would guess that your result set would contain a single column with
string data (char or varchar in SQL). If that's correct, then your
loop should look more like this:
while (rs.next()) {
rowArray.add(rs.getString(1));
}
You can also use the column name, as in:
while (rs.next()) {
rowArray.add(rs.getString(SourceTableName));
}
Your code would only work if the SourceTableName column in the
SourceTables table is of an integer type.
HTH,
Chad

Re: Copying from Result Set to Array List
Well, just that. The code you originally posted showed you trying to
retrieve integer data from your result set, but your table contains
string type data so your code wouldn't have worked. Now, the error you
posted looks like you are trying to cast your result to a String in
your onSuccess method. Your result will be an ArrayList. You need to
iterate it and read each string in it.

Re: Display tables of database in tree fashion
Rahul, That should be relatively simple to do. Use RPC for your client-server communication. On the server side, query your database for table names and send a ListString back to the client. Iterate the list, adding each item to the root of the tree and give each a child node with the text of Loading... (or something of your choosing). On the expand of the tree nodes, check the text of the first child node. If it is your stub text, make another call to the server for the columns of that table. When that call returns (callback onSuccess), remove the child node and add each item in the list returned. That will give you a dynamically loaded tree with table and column names. If you don't want it done dynamically, you can create a slightly more complex object to pass from the server to client with all of the table and column names and just the entire tree at once. As far as getting the table and column names, that will be specific to your database product, but it should be supported by all products. The drag and drop stuff isn't very hard either. You may want to use the dnd library from the incubator if you're not comfortable coding it yourself. When doing the drag and drop, you generally have a reference to the object being dragged, which in your case would likely be the TreeItem. Once the drop happens on the target, your TextBox, you just set the text to the value from the TreeItem. I know this is all very generic, but that describes how I'd implement it. Oh, I usually go the dynamic loading route when dealing with trees. HTH, Chad On Jul 9, 9:21 am, Rahul Mukhedkar coolrahul18...@gmail.com wrote: any suggestions anyone?

Re: show/hide widget based on user's credentials
Permissions aren't really checked on the server. I have tables in a database for users, roles, and rights. And I have tables that link them together users_roles and roles_rights. When the user logs in, and authentication is complete, the user data is retrieved along with the roles the user belongs to and the rights that belong to each role. The roles and rights are added to the user and sent back to the client. From that point on, the application can just query the user object for everything that it needs to know about the user.

Re: show/hide widget based on user's credentials
Well, my current application is an intranet application and uses NTLM authentication and that's what I was referring to. It's constantly authenticating the user I believe. On internet apps (and even some intranet apps), I generate a session id on the server side (something like a guid from the database), and store it in the user object and a session table in the database. Then, with all requests, I pass either the session id or the user object to the server with the request (depending on what data is needed for the request). The server will check the session table to make sure the session id is valid. I also sometimes store this session id in a cookie valid for a couple weeks to allow user's to stay logged in in some apps. If I'm not mistaken (which I very well may be), aren't these methods secure? I grant you, I'm by no means a security expert.

The roles and rights are added to the user and sent back to the client. From that point on, the application can just query the user object for everything that it needs to know about the user.

Re: Very basic LoginSecurityFAQ and GWT-RPC questions
eags,
In my apps, I generally keep a reference to the User object within the
app. Since, my current app works with browser history and can be
called with various urls, I check for the existence of a User object
after I parse the url, but before I load and show the content
referenced by the url. If there is no User object, I know the user is
just coming in and I can force a login.
HTH,
Chad

Someone I talked to in person (who otherwise didn't know about GWT
RPC) suggested I also store the role as in

otherwise mess with the user object every request. Does that seem
sane? I suppose I could also store a reference to the User object
since that is likely to get referenced pretty regularly. Any issues
with that scheme? (again assuming that storing the sessionID manually
is what I'm supposed to do at all).
On Jun 8, 11:27 pm, eags eagsala...@gmail.com wrote:
So I read the LoginSecurityFAQ (http://code.google.com/p/google-web-
toolkit-incubator/wiki/LoginSecurityFAQ) and I plan on implementing
logins exactly as in the FAQ. At a high level I believe I get it but
need help on the specifics so please be as detailed and specific as
possible in your responses. A link to an actual implementation of the
LoginSecurityFAQ's method would be ideal.
So here is my notion of what I need to do with some questions about
details:
1. I'm planning on using the google app engine's JDO implementation to
store all data. For each User object I intend to store the userID and
the jBCrypt hash of the password along with whatever other user data
in the same object. When a new user registers, I'll create a new User
object and store it.
2. When a user tries to log in the server uses the username to fetch
the User object and the associated hash to check if the supplied
password is validated by the hash.
Here is where I get confused and am not sure but here is my best
notion of what I should do:
I return a sessionID to the client. I have seen people mention in
other posts that a sessionID can be fetched by doing:
getThreadLocalRequest().getSession(); on the server. (Also do I want
to return the HttpSession or the use getSession.getID()???) Or can I
use any random number?? (sounds wrong). However I generate it, Is
this session ID something I need to store using JDO along with the
username and a timeout value so that I can subsequently validate that
the session exists and is still active? Or is the session and
sessionID something that just exists on the server and I just need to
get a reference to?
Either way I'm still fuzzy on details. If I do store
{username,sessionID,timeout} in a DB, do I then need to periodically
clear stuff out of there?? If they explicitly log out I can see
removing the object but if they just close their browser it would just
grow and grow right? I guess if don't duplicate usernames when adding
new sessionID at worst this table would contain all my users all the
time and have a bunch of timed out sessions.
Also, How do I invalidate a session ID right when they close their
browser? I guess I could first check for the existing session ID and
if the timeout indicates it shouldn't persist over browser restarts or
page closing then I can compare to getThreadLocalRequest().getSession
() and see if they are the same (will subsequent calls result in the
same sessionID iff the browser window hasn't been closed)?? Also how
do I know there are no duplicate sessionIDs handed out over time where
more than one might be active at once (if I wanted to allow users to
stay logged in perpetually?). I'm trying to answer some of my own
questions but I'm very fuzzy here.
If I don't store {username,sessionID,timeout} in a DB (and always just
use getSession().getID() to compare what the client sends me), how
then can sessions remain active for weeks even across closed browsers,
etc (assuming I do the thing where I store the sessionID in a cookie
and retrieve and try it before trying a new login).
Also, I never saw any mention of sending the username along with the
sessionID. Is that right?
Anyway, moving on to more confusion:
The FAQ mentions specifically that the sessionID should be included in
the *payload* of every subsequent RPC request. Does payload just
mean an additional argument in the interface methods in the service
like (from the GWT StockWatcher tutorial):
StockPrice[] getPrices(String[] symbols,String sessionID) throws
DelistedException;
Or are we talking about some other way to pass this to the server?
OK. Now on to a couple related GWT RPC questions.
So I have a few things the server will be handling for me, for
example:
String sessionID login(username,password);
String sessionID register(username,password);
bool isLoggedIn
Phantom Code Running
Hi all, I recently removed a column from a database. And, in turn, I removed references to it from my Java code (both client and server sides). Now, when I run my project, one of my RPCs throws an exception from SQL stating that the column doesn't exist. This exception is expected if I try to access a column in a result set that doesn't exist, but I'm no longer referencing that column. I deleted all references to it. I've done full text searches across my whole project. That column name isn't found. I've done a clean on the project. I've compiled the project. I changed obfuscation level and compiled again. I've exited Eclipse and gone back in. This exception keeps getting thrown. I even added a new method to my server side implementation class where the reference was just to make sure it should have to be recompiled. Nothing seems to help. I rebooted my machine and that didn't make a difference either. Any ideas how to make this deleted code not run?

Re: PushButton w/ image: How to avoid grey background
Anders,
I do this in my app. I call it an InvisibleButton. All you need to do
is alter the CSS. I copied the CSS from GWT's PushButton and renamed
the gwt-PushButton part to mm-InvisibleButton. You don't even need to
do that if you want that behavior for all of your push buttons. Simply
alter the gwt-PushButton CSS. Here's the CSS I use for my
InvisibleButton:
.mm-InvisibleButton-up,
.mm-InvisibleButton-up-hovering,
.mm-InvisibleButton-up-disabled,
.mm-InvisibleButton-down,
.mm-InvisibleButton-down-hovering,
.mm-InvisibleButton-down-disabled {
margin: 0;
text-decoration: none;
}
.mm-InvisibleButton-up,
.mm-InvisibleButton-up-hovering,
.mm-InvisibleButton-up-disabled {
padding: 3px 5px 3px 5px;
}
.mm-InvisibleButton-up {
cursor: pointer;
cursor: hand;
}
.mm-InvisibleButton-up-hovering {
cursor: pointer;
cursor: hand;
}
.mm-InvisibleButton-up-disabled {
cursor: default;
opacity: .5;
filter: alpha(opacity=40);
zoom: 1;
}
.mm-InvisibleButton-down,
.mm-InvisibleButton-down-hovering,
.mm-InvisibleButton-down-disabled {
padding: 4px 4px 2px 6px;
}
.mm-InvisibleButton-down {
cursor: pointer;
cursor: hand;
}
.mm-InvisibleButton-down-hovering {
cursor: pointer;

}
.mm-InvisibleButton-down-disabled {

Re: Composite - can click on one widget inside look like click on the Composite itself?
I do something similar with other events, so I would imagine it should work the same way. I have a class extending Composite that contains, among other things, a button. When that button is clicked, a CloseEvent is raised by the class. This is accomplished by having my class (extending Composite) implement ClickHandler (to receive the button clicks) and HasCloseHandlersBoolean (so other classes can receive the CloseEvent being raised). In my onClick method, I issue a statement like this (this statement exactly to be precise): CloseEvent.fire(this, true); I also do something similar with ValueChangeHandler and HasValueChangeHandlers to allow this class to raise ValueChangeEvent caused by internal controls. In your case, you will need to create a ClickEvent with the class as the source and fire it.

I call initWidget(the Grid). The issue now is that I register a click handler for the Label which should determine if the MenuItem was clicked or not. The Grid should not react on clicks, thus I do not register click handler for it. Now, naturally, the source of the click event will be always the Label. But in my application I need to get as the source of the event the MenuItem object, not the Label which composes just a part of the MenuItem Composite. Is there any smooth way to do that? My only idea is not to extend Composite class, but the Label itself and add it in a Grid. Is this a correct solution?

Re: how to overlay one grid over the other?
Suren, You could just put two grids in a HorizontalSplitPanel and set the splitter bar so that only the left column is visible. Or create two grids where the first grid only has one column and the second grid has all but the first column and put them side by side. You would have better control over the second scenario. Of course, in either scenario, the trick will be getting them to scroll together, but I'll leave that small detail to you. ;) HTH, Chad On May 14, 3:38 am, Suren nsurendi...@gmail.com wrote: Hi All, I want to overlay one grid over the other, so that I can create an impression that the first column can be a fixed/freeze when scrolling right.

Re: Getting User Credential from IE
Julian,
I did that here this way. I used jcifs (1.2.13 to be exact). You can
find it at this website:
http://jcifs.samba.org/
You'll need to add a filter to your web.xml file to specify your
domain controller. An example (the file I created) can be seen here:
http://www.milamade.com/code/gwt/web.xml.htm
You will have to change the ip address of the domain controller to
suit your needs. You will need to include the jcifs jar file in your
war when you deploy. To access the network alias, I added this method
to my server implementation class:
pre
package com.tuesdaymorning.datawarehouse.server;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class RPCsuperImpl extends RemoteServiceServlet {
private static final long serialVersionUID = 200611201219L;
protected String domain = TM\\;
public String getUserName() {
String user = getThreadLocalRequest().getRemoteUser();
if (user == null) {
return default;
}
if (!user.toLowerCase().startsWith(domain.toLowerCase())) {
user = domain + user;
}
return user;
}
}
/pre
One thing to note, if you are using IE, you will be signed in
automatically as IE does this invisibly. If you are using any other
browser, you will prompted with a browser dialog asking for your
username and password, IIRC.
HTH,
Chad
