Invoke GWT Entry point from extrenal java script included in separate/external HTML
Hi everybody, Thanks all for great co-operation and support. I am a bit new to GWT Though i have learnt a lot from this mailing-list in last couple of weeks I am stuck up with How to call GWT component ( mean to say ,give the the control to GWT entry point class for excuting onModuleLoad ) from extrenal HTML document. While working on integartion of GWT with external component, I am bit confused. My requirement is like this : I have a html displayed in the browser which is having mutiple buttons. This HTML is not part of GWT .This is being displayed in browser by some other component(currently .Net). On click of HTML Button in the browser I want to call gwt component that makes a call either to external tomcat server or displayes GWT widgets (widget button click , it also makes a call to external tomcat). One more thing is that can I have mutiple HTML for a single entry point so I can display various widget on requirement.I want to handle mutiple condition in a single own entrypoint class( inside the method onModuleLoad ) . Can anybody please provide ideas to get rid of this.

IE8
I've searched around this group, the buglist, googling keywords like 'gwt ie8' and 'gwt ie8 compatability', etc and I find little all together on GWT and IE8. I know IE8 is in beta, but still It makes me nervous when QA gives us blocker bugs like "Does not work in IE8 Beta". Obviously I need to (somehow) install IE8 and replicate the bug my QA team encountered and report it to the bugilist, but I was just curious if there was some official line on IE8 compatibility? You don't even have to go as far as "Google is fully supported to supporting IE8 when it emerges from beta", but maybe just a something like http://extjs.com/forum/showthread.php?t=45610";>this just to let us know you have your eye on the ball? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Google, how do I use your toolkit and make a site that is also searchable by your webcrawler?
I don't work for Google, and I'm not doing anything with GWT that I want to be crawlable, but you might search the web for "hijax", and see what you can make of it.

Google, how do I use your toolkit and make a site that is also searchable by your webcrawler?
I don't want to create two websites, one that is "traditional" i.e. link driven, and another that is ajax driven. I'm not even sure how to really manage that either, as any google search that hit the site would go to the link driven site, when I really want visitors to go to the ajax driven part. AFAIK, I also can't "fake it" by showing your crawler the the link driven site, and then somehow sending customers to the appropriate Ajax part of the site. IIRC, that is a quick trip to getting delisted. Is there some way to manage it with the "hyperlink" classes that I just don't understand? If I am missing something obvious, then please feel free to heap scorn upon me, after you give me a good link. So please Google, I want to use your uber-cool toolkit, but I need to know how to make it work with your webcrawler.

Re: Gwt with php
Another way to get PHP responses in hosted mode is like this
Create the url...
String url = Framework.getBaseUrlWithSlash() + filePathAndName;
where getBaseUrlWithSlash() is
public static String getBaseUrlWithSlash()
{
String url = GWT.getModuleBaseURL();
String baseUrlSplitOnSlash[] = url.split("/");
if(baseUrlSplitOnSlash[2].equals("localhost:")) url = "
http://localhost";;
return url + "/";
}
Then point your web server at your /public/ folder
If you regularly swap between projects, it can be a pain to reset the doc
root and restart, so you can have different projects using different ports.
Abyss is good for this. the free version only allows you to have one site
per server, but you can run as many copies of the server as you like, and
start them up as and when and if you need them.
Don't forget that if you are developing the client side, you can put a valid
response as plain text in the (supposedly) PHP (*.php) script file and then
you don't need PHP or a web server. You can also test invalid PHP responses
this way without having to screw up your system to get the invalid response.

In the project explorer, right click the project and select properties. Then select run/debug settings and click edit. Select the arguments tab. Under program arguments you need something like: -out www -noserver -whitelist "^http[:][/][/]127[.]0[.]0[.]1" http://127.0.0.1:4000/yourindex.html Under VM arguments you can do something like: -XstartOnFirstThread -Xmx1024M -Xms512M You don't need the -XstartOnFirstThread if you are not running on OS X. Note, you will need to have your server up and running or the host window will default to it's built in url.

Re: FlexTable odd behavior
Zach/Grundle/Whatever,
The setup you describe works perfectly OK.
If posters to this group don't post real code which exhibits the behaviour
they are complaining of, then it wastes the time of anyone trying to
help and also reduces their chance of being helped the next time. "Wolf!"

Re: FlexTable odd behavior
We have experienced issues with flextable when setting up the table in
DeferredCommands
e.g.:
List commands = new ArrayList(){{
add(buildStructure());
add(buildCellWidgets());
add(setInitialValues());
add(setBackgroundColors());
}};
Incrementally.execute(commands);
I am not sure what was happening, but basically it just didn't show &
no amount of debugging helped.
Perhaps this is what you are running into as well? We just reverted to
the non-deferred method of building the table.

private ChangeListenerCollection listeners = new
ChangeListenerCollection();
public abstract void manageAllListeners( ListBox listBox); // you
need to have this method that will manage your listener in this class
public iCombo () {
hPanel.add(ListA);
hPanel.add(ListB);
hPanel.add(ListC);
FillList();
ListA.addChangeListener(new ChangeListener() {
public void onChange(Widget arg0) {
// listeners.fireChange(ListA);
manageAllListeners( ListA); // use this
}
});
ListB.addChangeListener(new ChangeListener() {
public void onChange(Widget arg0) {
manageAllListeners( ListB);
}
});
ListC.addChangeListener(new ChangeListener() {
public void onChange(Widget arg0) {
manageAllListeners( ListC);
}
});
initWidget(hPanel);
}
private void FillList() {
ListA.clear();
ListA.addItem("ListA1");
ListA.addItem("ListA2");
ListA.addItem("ListA3");
ListB.clear();
ListB.addItem("ListB1");
ListB.addItem("ListB2");
ListB.addItem("ListB3");
ListC.clear();
ListC.addItem("ListC1");
ListC.addItem("ListC2");
ListC.addItem("ListC3");
}
public void addChangeListener(ChangeListener listener) {
listeners.add(listener);
}
public void removeChangeListener(ChangeListener listener) {
listeners.remove(listener);
}
}
now in the ComboParent when you try to create an instance of iCombo
it will ask you to add unimplemanted method ..see the example
/
* ComboParent.java
/
public class ComboParent extends Composite {
private VerticalPanel vPanel = new VerticalPanel();
private iCombo MyCombo = new iCombo(){
public void manageAllListeners( ListBox listBox){
// here you can add what you want
}
};
private Button btn1 = new Button("OK");
private TextBox txt1 = new TextBox();
public ComboParent() {
vPanel.add(txt1);
vPanel.add(MyCombo);
vPanel.add(btn1);
initWidget(vPanel);
}
}
in the same way you can go through the other class.
hope that will help you .

Re: GWT and servlet session
Thanks for reply, actually I don't know where exactly the problem is,
please bare with me.
First thing is : Compile/Browser option is not working when Filter is
enabled, this filter just checks for existing session using
request.getSession(false), if session exists request is valid other
wise I am throwing an error message saying "session is null".
In hosted mode everything works fine, no issues at all.
Another thing which I noticed is strange behavior of
request.getParameter method in case of RPC. RPC method are http POST
method and now I am passing sessionID with request payload i.e.
another parameter in my method
public String getData(String studentID, string sessionID);
I am trying to get this sessionID in my filter's dofilter method
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) ServletException {
if ( ! isLoginRequest(request) ) {
session = ((HttpServletRequest) request).getSession();
String sessionIDFromReq =
((HttpServletRequest)
request).getSession().getParamter("sessionID"); //this ID is null
if ( session.getID().equals( sessionIDFromReq) ) {
chain.doFilter(request, response);
} else {
throw new ServletException("session is null");
}
}
}
The only thing I know is for some reason I am not getting sessionID in
filter even thought session is created. Please help, I hope I made
things little more clear this time.
Thanks

Re: Remote exception cause is lost during serialization
We are using the following approach.
1 - On serverside, MyException is generated as we generate any other

2 - On Frontend, get the message using myExcepiton.getExcMessage();
Let me know if it help.

using OOPHM with a query string
I'm running GWT OOPHM on Linux with Eclipse and Firefox. In my
application's HTML file, have a Javascript object declared:
var myObject = {
param0: null,
param1: null,
param2: null
};
In the HTML file's tag, I call a Javascript function to read
and parse window.location.href, assigning the results to myObject,
which I later retrieve within my my widget via JNSI.
This all works fine if I compile my application, build a WAR file, and
run it under Tomcat. However, it will not work in hosted mode. I can
launch my application, and modify the query string:
http://...QSTest.html?gwt.hosted=127.0.0.2:9997¶m0=foo¶m1=bar
However my JNSI code sees $wnd.myObject.param0, etc as null.
So, (1) How do I use a query string in OOPM? and (2) How can I set the
query string in Eclipse 3.4?

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

Re: FlexTable odd behavior
Can you post code or sample of the code?
FlexTable table = new FlexTable();
table.setText(0,0,"hello");
table.setWidget(0,1, new Label("World");
table.setWidget(0,2, new TextBox());
perfectly works for me.

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

Re: linkable resources, caching, xslt xhtml generation with embedded js
Lawrence, To paraphrase you, what you would like to do is switch to a client- centric model of writing your client. That's good. GWT is good for that. The part that doesn't make sense to me is to keep the XML->HTML via XSLT transformations. That's not the way to build portable widgets in GWT. Why don't you try writing a simple client in GWT that gets Java Objects from the server, and constructs Widgets to display information and ineract with the user? Calling a widget constructor automatically invokes the right code for the browser where your application is running, where doing an XSLT transform puts you back in charge of managing N transforms for N browsers. As a bonus, you get to design, write and debug your entire application as if it were Java, including the user's interaction with it. Who wants to debug an xslt transform session?

confusion about gwt-tmp
when I start the gwt-compiler I can specify the -out parameter. This output directory also contains following dirs: * .gwt-tmp * myModule * myModule-aux I could not find the purpose of the .gwt-tmp directory in the docs. However, I think it's only needed by the gwt-compiler during the compilation process, because all files in this directory also show up in the myModule directory (except for the files in compilations, but I think those relate to the ALPHA.cach.html files in the myModule dir) If the above is true, I'd like to specify a separate location for .gwt- tmp much like the -gen switch spedifies a separate location for the .generated directory.

Re: FlexTable odd behavior
After trying the suggestion to use pixels instead of percent in the
flexTable.setWidth() method I have determined that the same error as
before repeats.
flexTable.setText(0, 0, "foo");
appears easily, but any instance of
flexTable.setWidget(0, 0, new Label("foobar));
where anything is put into the Widget, will not appear.
Any thoughts or advice?

Re: FlexTable odd behavior
Srini,
Thanks I will try that and let you know what happens. This still does
not adequately explain to me why a Text portion will show up, but not
a widget, including a Label widget that contains text. What is
different about setText and setWidget that a pixel width setting would
make a noticeable difference?

As I said, a Composite is meant to encapsulate (hide) the internals of
your widget.

Then either:
- don't implement SourcesChangeEvents but have 3 add* and 3 remove*
methods (one pair for each list). Each pair of methods will "drive"
its own ClickListenerCollection (hint: instead of implementing
ClickListener to fireChange on the collection, use a
DelegatingClickListenerCollection which does the job for you; see
below my rewrite of your ComboParent)
- use another kind of event where you can pass a "name" for the thing
that has changed (PropertyChangeEvent for example)
- somehow "abuse" the sender of the events (i.e. you register an
event on a widget but when it fires an event and call back your
listener, it isn't itself the "sender").

The argument to fireChange will be the "sender" passed to the
listeners. In the code I gave you, it was "this", i.e. the Composite
(see above, third choice, if you intend to change the value of this
argument).

OK so you chose to "abuse" the "sender"...
So how about setting a name to your lists (ListA.setName(...)) and
calling ((ListBox)sender).getName() in your listener? Kind of hackish
but "abusing" the sender is not better so...
> /
> * iComboParent.java
> /
> public class iComboParent extends Composite implements

DelegatingChangeListenerCollection
> public iComboParent() {
> vPanel.add(MyCombo);
> vPanel.add(btn1);
>
> initWidget(vPanel);
And just get rid of the following, which is already done by the
DelegatingChangeListenerCollection in its constructor:
> MyCombo.addChangeListener(new ChangeListener() {
> public void onChange(Widget sender) {
> listeners.fireChange(sender);
> }

If I were you, I'd really either
- create a new kind of listener communicating the changed "list name"
and selected value;
- expose the ListBoxes with getters (bad looking but I don't really
understand your layout, so...)
- use 3 pairs of add/removeChangeListener so by registering a
ChangeListener you know where to put the value; and expose the
selected value with a getter:
cp.addListAChangeListener(new ChangeListener() {
public void onChange(Widget sender) {
txtlistA.setText(cp.getSelectedValueA());
}
});
Anyway, your arrangement looks weird (to me)...

FlexTable odd behavior
I am currently developing an application where GWT has been the
primary API. So far things have gone fairly well until I began trying
to implement a data entry portion. I am experience strange behavior
with FlexTable where if I use
FlexTable.setText(0, 0, "foo");
FlexTable.setText(0, 1, "bar");
The data shows up as intended. However if I do
FlexTable.setWidget(0, 0, new Label("FooBar"));
FlexTable.setWidget(0, 1, new TextBox());
suddenly the components are not appearing on the screen. I cannot
figure out why setText data appears, but setWidget does not want to
render. I experienced the same behavior using Grid as well, so I am
at the point where I feel like I have missed something obvious. I
feel like I have tried everything, such as TextBox.setVisible() ,
TextBox.setVisibleSize("5"), FlexTable.setWidth("100%").
This really makes no sense. As for the other Widgets/Panels that are
being used see the following:
Specifically I am adding the FlexTable to a VerticalPanel, which is
then being added to a DockPanel.
i.e.
VerticalPanel.add(FlexTable);
DockPanel.add(VerticalPanel, DockPanel.CENTER);

Re: How to add thrid party Jar file
Hi, When using a GWT java resource 2 step are need: * the class file must resolved (add jar to classpath) or you IDE will complains with "unresolved classes". * the module "owning" that java resources must be inherited from your application GWT module, or the GWT compiler will fail (even if you add the jar to the classpath).

Re: Accessing gwt javascript from swing based web brower
Hi Frank, You should be able to make a call to GWT methods in JavaScript from within the WebRenderer Swing browser, and that would be through something called a JSNI bridge method call (JavaScript Native Interface). The idea is to call your GWT method from within a JSNI method, and bind GWT method to the $wnd variable (which represents the standard window object). Instead of going into all the detail here, check it out in our docs :-) It should help get you on your way: See "Calling a Java method from handwritten JavaScript": http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideJavaFromJavaScript Before trying that, though, is there any reason why you couldn't just pass in the Maps data coordinates through the URL. Is it because the size of the URL would surpass some browser URL size limits?

linkable resources, caching, xslt xhtml generation with embedded js
Hi all! Been lurking for a while now and I like this vibrant community a lot, so, thank you for that :) I need to redesign our web app so that it can support IE 7, gecko, Opera, webkit (one day IE8). The old one was hand crafted to work only with IE6. The idea is to use gwt and get coding on business requirements rather than trying to work around all browsers .. but I have a few question : Currently we serve dynamic pages and we use ajax just to get notifications if something changed. We then recreate the page with the updated content and send it back to the browser. Part of this pages is generated via XSLT (on server) We have our XML data we transform it via xslt with our stylesheet (xhtml) and we return the new consturcted page. This styleshee converts our data to all sort of controls : checkboxes, date pickers, drop down, labels, buttons, etc. Every "data" page can be bookmarked. What I would like to do is recreate the web app via GWT, but instead of retrieving an entire page every time some data is requested I would prefer to only do an ajax request for the xml and then to the transformation locally on the client. I saw someone porting sarissa to GWT so this should be possible. The only problem is that we embedded quite a few js calls in the stylesheet, and those now will need to be handled by GWT rather than the old, IE6 only, js scripts. I know that gwt compress/obscure the output js to make it faster, so I wonder, how can I mix the two ? Is it possible ? Also, if I do everything via ajax/xml, does this mean people can no longer save link to pages, bookmark them ?

Sure you can: specifies that the package $basePackage.data should be considered as client-package as well. So if your GWT.xml-file resides in com.example.mygwtproject, the package com.example.mygwtproject.data is regarded to contain client-classes as well. I haven't tried it with "absolute" package-names, so I'm not sure if you can specify org.example.someotherpackage as source-package.

Re: Newbie question - adding GWT to my existing application
Hi Walden,Thanks for that. I'm going to give this a try and let you know what I have. To clarify though, whenever we use the tag in the pkg1.gwt.xml, is there not a way to have this defined for a whole package as opposed to each singular class? I would think that many large projects would find this an annoyance if it had to be done for each class right? Or are there are considerations I am not thinking about?

Re: Background color for DecoratedTabPanel
You might try 'background-color' instead of 'background'. But if that doesn't work, then you might as well roll up your sleeves and learn to debug the DOM. Get one of the DOM inspector browser plug- ins and learn how to use it.

Re: Best practices
Hi Stefan, Maybe because there are so many different kinds af application you can build with GWT that it's hard to say if there is any one "best practice" - perhaps there there are number of good blueprints suitable for particular types of application. But for me there are a few guiding principles I adhere to: 1) GWT, based on Java, is fully object oriented, so all OO principles apply - they are well known. 2) Use the GWT event model for sending messages between widgets, do not hold any direct internal references to peer widgets to call peer methods directly. In the face of complexity this simplifies code and makes it more robust. It also means that pieces can be easily swapped in and out of the application and it makes testing and maintenance a lot easier. This is the Observer pattern, it has stood the test of time and it avoids tight coupling between components. In practice this means that a parent widget typically instantiates and lays out its child widgets and then hooks up their event listeners etc for them, but the children have no idea who their parent is or who their peers are - they just broadcast events which other widgets might listen out for. 3) The exception to this rule is where you have a group of widgets that work very closely together for exactly one purpose - in OO parlance are highly cohesive - so that to all intents and purposes they have little or no relevance to anything outside that purpose. In this case it can be not only acceptable but probably desirable to use direct method calls between them. I'm not sure that there is an accepted name for this pattern - I've seen things like "goal-oriented windows" etc - and in GWT it is tempting to call it a Composite, but although related, GWT's Composite isn't exactly the same thing, nor is the GoF definition of it. Two examples of what I mean by this are a) a form with a number of input fields, list boxes etc, where you might want to do validation/auto-suggest work on the fields, and b) a navigation structure, e.g. a Tree, where you also have a button bar with a range of tool buttons driving functions off the tree's selected item and might need to turn themselves on/off depending on the item selected. It can be more efficient and basically easier to put everything in one class and have the individual field/buttons etc call each other directly via private access in this situation. You would typically use a GWT Composite to implement this pattern. 4) However you need to be careful with this exception and use the concept of "granularity" - a component should be neither too big nor too small, but just "right". What "right" is is matter of judgment. When I was learning C++ in college I was taught that the "right" size of a function was usually between 5 and 12 meaningful lines of code. My own rules of thumb on this are that I do not like GWT classes to have more than about 100-150 LoC max. If they go over this and the class qualifies as a "single purpose unit" then I tend to break it up using private internal classes. If it looks like it's going over about 500 LoC, then I break it up into separate public classes if I can and go back to using the Observer pattern and the event system. But this a judgement call, a matter of craft IMO rather than science and situation vary widely. 5) Decide early on whether you are after an application that looks and feels like a web page or like a desktop application. Outside of aesthetic considerations, it is technically more difficult to get a GWT UI to work perfectly completely contained within the browser's window area, resizing itself perfectly etc and it will cost you some to do so. The browsers think of everything as a document so their natural tendency is to extend the height of the document, invoking scrolling, and not to contain within the available visible client area height. if you want a desktop style app, then it's probably a good idea to do extra work up front on the overall layout mechanisms until you get it working properly. If you are used to windows style GUI programming, maybe Swing or SWT, or you are writing a business application, it can be difficult to choose on this one. At the end of the day customer perception is all, but I think that if your users will be happy with a more "web style" layout then it's probably best to go that way. I would recommend you trial some prototypes early on to find out. Ask yourself whether Google tried to copy Outlook when they made GMail. 6) Plan your asynchronous RPC calls out in the large up front and plan for them to change as you find out if your initial decisions where good - in most non-trivial apps I think some changes in approach will become necessary as real performance figures start coming in. RPC is a trade off between keeping the number of calls to a minimum whilst at the same time keeping the size the packets to a reasonable level, and no two situations will be identical. Aim for a response time of <1s except for situations where that is
Re: GWT with struts
Please be careful with terminology. When you say "GWT to call struts action", do you mean a remote procedure call, or do you just mean a link to a new page that happens to be built by a struts action? A GWT page is like any other page in its ability to embed links to other pages. Could you explain more about how calling a struts action from a GWT page gives security (and we're not talking "job security", I assume ;-).

Re: how to access event from another widget
Thank you very much, thomas
here's the final sample code and it really works... :)
but the problem is, in the MainMenu, I don't know which listbox that
send the listener.
in the MainMenu, I provide three textboxes
txtListA = catch the event from listA
txtListB = catch the event from listB
txtListC = catch the event from listC
so, I have to know first, the name of the sender widget, (which is
listA? listB? or listC?)
then set the txtListA.setText(listA); and so on
I have no idea, how to get the sender name.
I have tried sender.getclass().getname() but the result is not what I
want.
please help me (again) ;)

Re: GWT and servlet session
I'm not sure, but I think Tomcat should treat http://localhost and http:// as different origins requiring separate sessions. If this is your only problem, then don't use the IP address to access your site. If it's not the only problem, then post some meaningful diagnostics from your server log. You should have done that in your first post.

Re: Hmmm - new analytics (ga.js) integration?
Hi Pete,
In my experience, when work with com.google.gwt.dom.client.Element on JSNI,
it's simple if we consider that Element as javacript object directly(in
fact, Element is instance of JavaScriptObject). So we don't need to use JSNI
access method like
@com.google.gwt.dom.client.Element::setInnerHTML(Ljava/lang/
String;)'. We can call that method by element_instance.setInnerHTML ,
probably using elementInstance.innerHTML="and others"
I hope that will be usefull for U

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

then you use your ImageBundle and pass the image to this widget...

I still don't see a need for the creation of files but it is looking more like a special URL to be constructed. Again RequestBuilder would be the class of choice in that case. On the other hand, if your JSP- page expects a previous file-upload, you're screwed. In that case, before starting a Signed Applet Project, you should consider extending your JSP-page/servlet to accept the "file" as content of a POST-request. > Sorry to ask Once more about (2) as I am bit confused , does RPC mechanisnm > work on production environment also. If yes ,Can I process as mention in RPC works on production systems as well. gwt-servlet.jar and your server- classes must be in the classpath of your web-application/server.

Hi, I'm not sure if I got exactly what you mean but there's a widget in GWT called PopupPanel. > But I can't make it not disappear after a certain time In PopupPanel you can set in a constructor the "auto-hide" property which tells the panel whether to close automatically or not. For more info about PopupPanel see: http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/PopupPanel.html Or, you can create a custom class based on DialogBox. PopupPanel does not contain the "close button" and with DialogBox you could add it in your own. The DialogBox docs can be found there: http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/DialogBox.html Be careful, the PopupPanel and the DialogBox are both not accessible with keyboard.

iCombo has to fire events on listbox's change event; and ComboParent
has to fire events on iCombo's event; then MainMenu can register as a
listener to the ComboParent instance.

The goal of a Composite is to mask the internal implementation
(encapsulation) and expose its own API. It doesn't matter to iCombo
users that it's made of three ListBoxes or a set or RadioButtons or
whatever other widget; what matters is that some events are fired in
response to changes (generally in response to user interaction).
(note: I wouldn't implement ChangeListener on iCombo, it's an
"implementation detail"; I would rather have a ChangeListener stored
in a private field: private ChangeListener listener = new
ChangeListener() { ... }; )
iCombo should implement SourcesChangeEvents:
private ChangeListenerCollection listeners = new
ChangeListenerCollection();
public void addChangeListener(ChangeListener listener) {
listeners.add(listener);
}
public void removeChangeListener(ChangeListener listener) {
listeners.remove(listener);
}

Re: * No source code is available for type java.io.BufferedWriter; did you forget to inherit a required module?*
Hi Lothar, Thank you for providing such great help. The Actual requirements is to add the comments for each item appeared on the browser. I have created a richtextArea with the buttons for entering the comments for each clicked item shown on the browser. Now, once click over the buttons, It should be submitted to web server( tomcat ) already running for the whole product to save in the server filesystem.This is external webserver not gwt tomcat web server. The main issue is that jsp existed on external webserver accepts only file path to save the comments content. So I am force to create file having comments for each clicked item on the browser.For avoiding the creating files on client, I had suggested no (1) mentioned below. Is this right fit? .

My googlebot approach for GWT: UserBotRouter
Please advise concerning my approach for enabling googlebot to index my GWT site: http://www.SudokuComplete.com/ First, I needed to create a static, flattened, html-only view of my website. To do this, I created a simple .Net program that uses the IE WebBrowser control to navigate to my GWT site. The program takes a URL with a history token, let's the browser run through the GWT javascript, and then saves a copy of the resulting DOM html to a file with a name based on the history token. This file is essentially an html-only view of the site as-of the history token. I use the program to save static versions of each of the major history tokens on the site. These files are the ones I want googlebot to index. And to provide navigation for googlebot, I add links between all the files at the end of each of them. Next, I created my "UserBotRouter", a .Net HttpModule (analagous to a J2EE Web Filter) that analizes the incoming requests to the website. It checks the UserAgent header to see if the request is being made by a bot or a standard browser. If it is a bot, then it routes the request to the appropriate static html page (created in step #1). If, however, a standard (non-bot) browser requests one of the static pages, then my module sends an HTTP redirect to send the user's browser to the corresponding GWT page including the respective history token. In this manner, I am able to route users to the GWT pages, and bots to the static HTML pages. Am I missing anything? Does this sound like a workable approach? Can GWT build something like this into their compiler? That is, if GWT compiles different versions for the different browsers, why not create a set of standard "bot" pages. In the module XML file the developer could specify the tokens for which GWT should create html pages. GWT would use an approach similar to mine above to create static html files for the tokens. Then, in these static html files, some javascript could redirect the browser to the corresponding GWT url. This javascript redirect would affect actual user's browsers, whereas bots would continue to read the page as-is, following links to the other static pages. Please let me know what you think, john... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

If it's for a file-upload, there is a HTML-tag for that, i.e. you can use that inside GWT as well (using the FileUpload-widget). So if it's a file-upload we're talking about, use that, otherwise you will have to go the Applet-way or try to think over your concept and find a solution that doesn't need a local file-system.

Place a
GWT.log("submitted", new Exception());
next to the Window.alert and look into the log-window where the
second call comes from. This should help you to find the reason
why you call it twice.

Re: * No source code is available for type java.io.BufferedWriter; did you forget to inherit a required module?*
Hi Everybody, Thank you all of providing much needed support. Though I have implemented this by calling external java script using JSNI , I would like to change the way if it doesn't last long. Actually,I wanted to send the request parameters for file information to Tomcat webserver( already implemented for whole application. ). But The main problem is that I have to use already existing jsp which takes only file path.So, 1) Would this be good if I write a servlet on webserver which would write the file and use sendredirect to jsp? 2) Can I make a call rpc call to my own servlet in gwt tomcat server which will write a file and sendredirect to my jsp on application web server.? But , As per my study , rpc call is only for debugging so, it wouldn't valid for production server.is this correct.? 3) or, as one of u suggested , write a applet with extended signature and use some magic of JSNI.( for this, can anybody provide some more detail. ) please provide the suggestions and ideas if any others.

Re: Form submitted twice?
Hi
hmmm...you should only see it once, as mentioned.
1) Are you sure you haven't added the listner twice?
2) Can you post you code up?
3) Are you sure you're not submitting twice?
mon3y.

Urgh, Sunday evening mistakes - it is of course a link to classes available on client side; on server side you can use all of Java. //A On 29 Sep, 01:11, Arthur Kalmenson <[EMAIL PROTECTED]> wrote: > That link is for Java classes that can be used on the client side, not > the server side.

Re: connect to mysql datbase

First of all, you can't connect to MySQL using JDBC inside the GWT-client (there are about thousand threads about this in this forum, so I'm not going into detail here), so you have to implement a RemoteServiceServlet that is called by the GWT-client (I assume that you use Java on the server-side). Inside the servlet, you connect to the MySQL-database. There are a couple of examples out there, here is one: http://www.stardeveloper.com/articles/display.html?article=2003090401&page=1 After that you execute the SQL-statement and return the result to the client. To be able to do that you have to create a resultset that can be serializied (java.sql.Result is not part of the JRE emulation of GWT), e.g. a String[][].

The JRE Emulation is valid for the client-part. Because it's a subset of the Java Runtime Library, it's of course valid for the server-side as well.

There is no Javascript-function that allows you to write to the local filesystem. There are only hacks taking advantages of bugs in browsers to achieve that but this kind of thing don't last very long and is nothing I would expect inside a widget-library. > Please correct if I am wrong at any point.
