Best practice to serialize a org.w3c.dom.Document over RPC?
Hi guys, A (hopefully easy) question: what is the GWT 'best practice' to take a server-side DOM built with org.w3c.dom.Document and pass it over RPC? Clearly once on the client-side it needs to become a com.google.gwt.xml.client.Document, and I can achieve this by serializing to and from a String of XML, but is there a better way? Something more performant that uses some built-in DOM serialization capabilities?

Re: align the widgets in DocLayoutPanel
Hello Roliveria, Thanks, you right, p.addEast(sampleWidget,20); adds a new East edge every time.

Re: Best practice to serialize a org.w3c.dom.Document over RPC?
I agree with Thomas. XMLParser.parse(xmlString) uses the browsers xml parser which should be reasonable fast. If you want to further process the XML document (e.g. map it to POJOs) feel free to take a look at Piriti: http://code.google.com/p/piriti/.

How to put a CellTable into a fixed relative sized div?
Hi! I'd like to put a CellTable into a fixed size div element, but my problem is that when the table's setData method is invoked, the table changes the size of the wrapper div element somehow, but only in the case when width and height is specified in percent. If I specify sizes in px, the result is satisfactory, however I'd like to work with relative sizes. Here is my code: g:HTMLPanel div style=border: 1px solid red; width: 600px; height: 600px; overflow: scroll; c:CellTable ui:field='table' / /div /g:HTMLPanel do you have any ideas or suggestions? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How GWT-RPC handles polymorphic serialization?
The GWT has the standard GWT-RPC to make easier to create RPC calls and fetch data from the server, but this tool only works if we have Java on the server side. In my current project, the server side will be .NET based. So I wrote a JSON-RPC library which implements the JSON-RPC standard to provide RPC facilities. The library is OK but I don't have the serialization facilities and I need to manually populate a JavaScriptObject with the information that i want transfered. I started now to write a automated serialization for the objects based on Annotations and Generatos, but i don't know how to discover the type of my object at runtime. I have a lot of polymorphic associations and will be nice to have some of those in my DTO's. So is there a way that I can get the type of a Object in GWT at runtime or I need to provide some Interface that my DTO's will need to implement that will have a method which returns some value that identify the type? If I need to use the Interface approach, is there a way that using generators I change the code of the class and then implement in a automated way? (Whithout defining the generator for each class in the module.gwt.xml) Thanks. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

iOS (iPhone/iPad) breaks the GWT spinner
This isn't strictly a GWT question; it affects any JavaScript application deployed to iOS. Any time the user touches an image for a second or so, a popup menu appears with the options Save Image and Copy. This is just a nuisance with simple button images, but it completely breaks the GWT spinner. You can see the problem if you navigate here in an iPhone or iPad: http://collectionofdemos.appspot.com/demo/com.google.gwt.demos.spinner.SpinnerDemo/SpinnerDemo.html You can tap an arrow to move a spinner a single 'tick'. But if you press-and-hold the arrows (the core functionality of the spinner), that iOS popup image menu interrupts the operation. Has anyone else struggled with this and found a way to suppress that behaviour? Jim. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JSON Problem

In ther server the json-string will be accessible by the parameter
jsonrpc-call.

XMLParser Question
StringBuffer xmlBfr = new StringBuffer();
xmlBfr.append(Layout);
xmlBfr.append(Column type=\Middle\/Column);
xmlBfr.append(Column type=\Middle\/Column);
xmlBfr.append(/Layout);
String xml = xmlBfr.toString();
Document document = XMLParser.parse(xml);
Element element = document.getDocumentElement();
NodeList layouts = element.getElementsByTagName(Layout);
for (int k = 0; k layouts.getLength(); ++k) {
Element layoutElement = (Element) layouts.item(k);
NodeList columns = layoutElement.getElementsByTagName(Column);
for (int i = 0; i columns.getLength(); ++i) {
Element columnElement = (Element) columns.item(i);
String type = columnElement.getAttribute(type);
Window.alert(type);
}
}
I try run the code above, i found that the XMLParser is not working
well.
NodeList layouts = element.getElementsByTagName(Layout);
layouts.getLength() should return 1, but it is return 0!
XMLParser just cant parse the xml string.
May i know, am i doing any mistake when using XMLParser as above?

Re: Eclipse plugin suggestion
This is right, what we really need is Google to open source the plugin, but they don't want to I wouldn't confuse don't want to with not quite yet. From the FAQ: http://code.google.com/eclipse/docs/faq.html Q:Is the Google Plugin for Eclipse open-source? A: Not yet. For the initial release, we wanted to get you the plugin as fast as possible. However, we expect to make the source public in the near future. This is no different than GWT itself. The stated intention since GWT was released was to make it open-source, but it took almost six months I think before they were able to do so. It will get there.

Perhaps there can be an option on the new project dialog that lets you turn off the sample code, and only created the entry point, module config, and a deployment descriptor with only the default page name? This seems to be fairly standard in project creation wizards. I couldn't find a thread or issue on this, but it seems like their should be one. Anyone disagree with this?

how to make this mouse over effect?
i have a flextable where there an anchor link in cell(0,0), and there is a button in cell(0,1) which is invisible by default. how to make it such that, when mouse over the flextable, the button in cell(0,1) becomes visible; when mouse out the flextable, the button becomes invisible again? the difficulty is, flextable does not have mouseover and mouseout handler. but if i add the flextable to a focuspanel, the anchor and the button would then be 'masked' by the focuspanel then cannot be clicked. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JSON Problem
The response comes async.
When the response from the server arrives at the client the method
onResponseReceived in the RequestCallback object is called, if an
error hapens the the onErrormethod is called.
The RequestCallback object is the second parameter in the sendRequest
function call.

== 200 || response.getStatusCode()

JSONP + parameter signature
Hi, As many other frameworks, on each JSONP request, GWT creates a new randomly named callback function. That's great, except when the web service (as Flickr) that you are requesting requires the sent parameters to be signed. As the callback function is passed as a parameter in the URL, the web service requires it to be in the parameter list that will be signed. As the random name is generated just before sending the request, I just cannot sign the parameter list. I found no direct way (except re-implementing the internal GWT classes) of knowing the callback's name before making the call, and then signing the parameters. Any idea of how I can do that ?

Easily fixable: Issue 2892 Option Element warnings
I would like to bring an old Issue 2892 to your attention. Some option fields used as date selectors in our application keep outputting many annoying warnings. Causing a 15 to 20 second wait before we could continue on some views. Particularly year selection has a lot of years because they are for selecting birth days of older people. We could set the logging level higher but then we don't see the normal logs we included in testing. The fix is very simple. Somebody could remove the returns from the methods that should return a void to remove the warning. This is a very small task but not yet done in the years in the existence of the issue report. It would make us very happy to properly test those views with option elements in our app. :) The issue with a proposed fix: http://code.google.com/p/google-web-toolkit/issues/detail?id=2892 (I am arquelis in the issue and posted a possible fix months ago) Could somebody in the list find a way to have this issue fixed?

GWT lifecycle
Hi, I'm working with GWT and I have a couple of questions. I need to know the exact life cycle. How is the project created? How can you define what is changed into **.nocache.js?

Image Format Conversion + alternative to FileOutputStream
Hello,
I firstly made a simple program that converted images to any of the
desired format by user using JAI.
Then i thought of trying similar stuff on GWT.
As FileOutputStream idoes not work with GWT, i first tried to make a
program where user can upload an image and then download it.
Now i want to kind of merge these two and i'm really very confused.
String fileName = (String)req.getParameter(fileName);
File file=new File(c:/users/rohit/desktop/+fileName);
int length=0;
// Load the input image.
RenderedOp src = JAI.create(fileload, file);
// Encode the file as a JPEG image.
OutputStream os=null;
try {
os =new FileOutputStream(file);
} catch (FileNotFoundException e) {
System.out.println(Cannot write the JPEG File);
e.printStackTrace();
}
JPEGEncodeParam param = new JPEGEncodeParam();
ImageEncoder enc = ImageCodec.createImageEncoder(JPEG, os,
param);
try {
enc.encode(src);
} catch (IOException e) {
System.out.println(Exception in encoding);
e.printStackTrace();
}
try {
os.close();
} catch (IOException e) {
System.out.println(Error in closing file);
e.printStackTrace();
}
ServletContext context =getServletConfig().getServletContext();
//String mimetype=context.getMimeType(fileName);
String mimetype=image/jpeg;
resp.setContentType(mimetype);
//resp.setContentLength((int)file.length());
resp.setHeader(Content-Disposition, attachment; filename=
\+fileName+\);
ServletOutputStream op = resp.getOutputStream();
byte[] buffer = new byte[4096];
DataInputStream in=new DataInputStream(new
FileInputStream(file));
while ((os!=null)((length = os.read(buffer))!=-1)){
op.write(buffer, 0, length);
}
os.close();
op.flush();
op.close();
}
above is the code of the server side. I store the file on hard disk
after getting it uploaded from user.
The above code is wrong. Basically i need an alternative to
FileOutputStream.

the difficulty is, flextable does not have mouseover and mouseout

the button would then be 'masked' by the focuspanel then cannot be

I18N and dynamic texts
Hi there, For a client i'm in search for a solution to I18N and dynamic texts. Could you help me out in finding the most suitable design strategy for this problem? The application has some texts like menu items, headers, introduction paragraphs and help texts. These texts should come from some database tables and should be in different languages. Texts may also very on the user role and the company where the user is employed. Of course i would like to inject the views (i'm using the MVP pattern from the Contacts example) with some class that implements a textBundle interface or something like that. The Messages and Constants strategy comes very close, but it depends on property files. The client really wants to connect to the database with a homebrew MS Access client.

Re: RPC - which exception types may be used???
From what I know you can use any type of exception, but: - GWT needs to know the source (file) of the exception (it's either in an inherited module or in your 'client' code or what ever package you declared in your *.gwt.xml) - it needs to be serializable (implement Serializable and do not forget empty constructor) That's it I think.

Re: No source code is available
It may be that you already know this but, the very important attitude to acquire before starting to use GWT is - GWT is not Java runtime, GWT is Javascript runtime - All GWT Java code is compiled to Javascript runtime - GWT is compiled to run on the browser client - Any Java code hoping to be used for GWT must implement Serializable. - Therefore, any Java lib called by your code must have their source code available to the GWT compiler to translate into Javascript. - Consequently, any lib called by a lib called a lib ... called by a lib has to have its source code available to the GWT compiler. If the Java source dependency is broken at any point due to unavailable source code, your GWT compilation will fail. - Your Java source code dependency chain can be broken by your Java lib calling a library that does not implement Serializable, or calling a library written in another language. You seem to be confusing between the Java code in GWT and Java code for JVM. GData libs and UserService runs only on the JVM and do not run on the browser. The last time I used GData, I wrote the Java code calling GData libs to run only on the server. I used GWT RPC for the GWT client to call the server-side to trigger GData calls, and after that, the server passes the results of the calls to the RPC callback of the GWT client. Similarly for GAE userservice - there is no Java source code available for UserService. If your GWT app needs to call UserService, you need to call UserService on the server only and pass any UserService info as serialized structures to the GWT RPC client callback. To effectively use GWT in client-server mode, you should familiarise on how to exploit GWT RPC. Attitude-wise, always treat GWT client Java code as though it is written in a language other than Java to avoid confusing between JVM Java and GWT Java. You cannot willy-nilly lift off any Java code and bind them to your GWT Java code. (Defn of willy- nilly: taking actions by random will without considering their implications/complications). This is an 8-part series I blogged about combining GAE, GWT and GDATA: http://h2g2java.blessedgeek.com/2009/08/tablemgr-gae-gwt-gdata-with-rpc.html.

Part of my isLoggedIn method looks like this: HttpServletRequest req = getThreadLocalRequest(); getThreadLocalRequest().getSession(false); getThreadLocalRequest() returns null.

Re: how to enable scrolling for app using DecoratedTabPanel?
Hi Ingo, First of all, CSS(3) is a failed descriptive language. Inspite of its complexity it does not support some basic requirements of layout management. So you have to choose a layout which is possible with CSS. You can't define a layout and find out how to do it with CSS. I watched your video. I detected things which went wrong. The TabPanel has still a flow layout. It grows when a inner div moves to the next line. You probably want the tabPanel grow and shrink with the browser window. This is possible with an absolute layout (LayoutPanel) However, the panel with search has actually a flow layout, but this conflicts with the above. You should give this panel a fixed height. My proposal without looking into your source, use RootLayoutPanel add SearchPanel with TopHeight (0, height) add TabPanel with TopBottom (height, 0) (both panel with LeftRight (0, 0) This should make your TabPanel grow and shrink with your browser window. A the very moment the TabPanel could not grow on inner changes, the scrollbar has a chance to appear because the inner needs to be larger than the outer.

Re: I18N and dynamic texts
Well, You can create a class that wraps a JavaScriptObject which contains a Dictionary with your keys and values. And before starting your application you can make a HTTP Request to fetch the JSON data (or part of it). Than in the server-side your write some code that send the values from the database in the JSON format. Of course you should not download all the keys from the DB at the same time, but you can download part of it when you need. Since you will use the MVP, you can write custom events when the download of the JSON strings success or fail.

Re: Role-based security and widget visualization
acris-security depends on some core modules and tries to be as separated as it is possible. It is designed to fit into (hopefully) any environment but currently we have integration with Spring Security only. Nevertheless we are open to any discussion regarding extensions. The client is built in javascript and transferred to the user thus the logic primarily shows/hides or enables/disables the components. Server side security is always required because you cannot rely on the information sent by the client. Regarding documentation - it is not complete yet, we are working on it these days. @Secured annotation on top of the class propagates authorities to field's @Secured so you don't have to repeat it. For each field that has to be secured the @Secured annotation must be put on top. Interface must be implemented so generator can process it. Approximately in two days the showcase will be available.

Re: iOS (iPhone/iPad) breaks the GWT spinner
This same basic issue breaks the SliderBar in iOS: http://google-web-toolkit-incubator.googlecode.com/svn/trunk/demo/SliderBar/index.html The SliderBar is affected by two different issues: (1) Click-and-hold on the slider image brings up that iOS image menu; and (2) Click-and-drag would be intercepted by iOS to drag the entire screen.

Well, that's certainly one example.
I was looking for something that would get to the 2.1 stuff from Fred
Sauer's logging.
Here's what I've found so far:
o Using the following idiom in each class that used the FS logger:
final private Logger logger;
ctor {
logger = Logger.getLogger(this.getClass().getName());
}
then, where I used
Log.debug(msg); // where msg included the class name
switch to
logger.fine(msg);
is a bit verbose in that certain GWT classes are also intruding at the
FINE level. I will switch to a different log level. Otherwise, all is
copacetic.
o Go through /all/ the log handlers and disable the ones you don't want.
I forgot SimpleRemoteHandler and it took a few minutes to discover the
problem.

Re: need help on JSON request and response on UI only
On the server-side, I use
com.google.gson.*
On the client-side, I use
com.google.gwt.core.client.JavaScriptObject;
com.google.gwt.json.client.*;
There are two modes to using these APIs.
- Use GWT RPC to send Java structures back and forth.
In this mode, you are blind to JSON and never need to even refer to
any JSON API.
- Send JSON explicitly and therefore having to be aware of JSON APIs
on both client and server side.
What concerns you is the second mode.
For example, I am writing a framework which inspects the DAO on the
server-side to construct the JSON representing those structures. The
GWT client reads the server's JSON representation and data and builds
the GWT (or SmartGWT) Ui dynamically and fill them up with data
spontaneously.
On the server-side, using com.google.gson.*, for example,
final JsonObject schema = new JsonObject(); // construct the schema
root as hash node.
schema.addProperty(name, name); // add key-string value pairs
JsonArray elements = new JsonArray(); // create a JSON array
schema.add(elements, elements); // add key-child node pairs to hash
node.
JsonObject elem = new JsonObject();
elements.add(elem); // json obj to jsonarray.
Gson gson = new GsonBuilder()
.setPrettyPrinting().create();
gson.toJson(schema); // print the JSON representation to output.
On client-side, read this article
http://code.google.com/webtoolkit/articles/using_gwt_for_json_mashups.html.
And then you could use my library by extending
JsonRemoteScriptCall.java at
http://code.google.com/p/synthfuljava/source/browse/#svn/trunk/gwt/jsElements/org/synthful/gwt/javascript/client.
This library works on the premise of jsonp. The principle is, you
modify your server-side JSON provider to do envelope the JSON
structure as executable javascript:
var jsdata = {
// json structure
}
eatJson(jsdata);
On client-side:
import com.google.gwt.core.client.JavaScriptObject;
import com.google.gwt.json.client.*;
JsonRemoteScriptCall myJRSC = new JsonRemoteScriptCall() {
extends JsonRemoteScriptCall {
@Override
public void onJsonRSCResponse(JavaScriptObject jso) {
if (jso==null) return;
this.ignite();
JSONObject json = new JSONObject(jso);
// traverse your json tree here.
}
}
What you need to take note is how to trigger reading in the JSON:
myJRSC.call( url of json data source, eatJson);
Notice that the callback onJsonRSCResponse is mapped to eatJson by
this utility, so that at the end of the json file, eatJson is executed
as a javascript call which actually runs the callback
onJsonRSCResponse.
Take note that on the client-side use of com.google.gwt.json.client.*
APIs, you have to be quite explicit in testing if a node is another
node, is an array, is a string, etc:
static public String getStringValue(JSONObject json, String key){
if (json == null || key == null )
return null;
JSONValue typejsv = json.get(key);
if (typejsv!=null){
JSONString typestr = typejsv.isString();
if (typestr!=null)
return typestr.stringValue();
}
return null;
}
static public JSONArray getJSONArray(JSONObject json, String key){
if (json == null || key == null )
return null;
JSONValue jsv = json.get(key);
if (jsv!=null){
return jsv.isArray();
}
return null;
}
static public JSONObject getJSONObject(JSONObject json, String key){
if (json == null || key == null )
return null;
JSONValue jsv = json.get(key);
if (jsv!=null){
return jsv.isObject();
}
return null;
}

unfamiliar with for setting up properly with respect to the
appropriate libraries being available. I really just want log messages
to go to the console... any information leading to this situation will
be rewarded with beer. :-)

Re: GWT printing on dot matrix printer
What example? As far as I know it would be the browser and css (in addition to the printer driver) that would control the printing. Look into those three areas (browser, css, and driver). I think you may have a misunderstanding of what GWT is.

Cross Site Linker Code Splitting
The Developer's Guide mentions that Code Splitting is not supported by the cross site linker http://code.google.com/webtoolkit/doc/latest/DevGuideCodeSplitting.html What are the technical reasons for this? Can we expect support for this in the Cross Site Linker soon? Thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: xs linker does not support all GWT features?
Is there an issue in the issue tracker in regards to this? I would like to track when and if this fix makes it into a release, but couldn't find anything by searching on xs linker and code splitting On Jul 3, 12:31 pm, Brendan Kenny bcke...@gmail.com wrote: Not sure if you meant to write just to me or reply to the list, but I'll forward this on to everyone. Shortly after I wrote that post it was discussed on the Contributors list that there was indeed a fundamental issue preventing the xs linker from working with code splitting, but that a patch was in the works. The fix landed on trunk in March http://code.google.com/p/google-web-toolkit/source/browse/trunk/dev/c... but I'm not sure if that made it into 2.0.4 (or whatever) or if it will be released with 2.1.

Are there any other features that are not fully supported? I am currently trying to build a framework that allows for easy wave gadget development in GWT (including side-by-side testing of gadgets in hosted mode). Given the shortcomings of the gwt-gadget linker (which produces only one huge code file instead of one for each permutation), we were trying to figure out what else we could do over at the wave dev group. (you can follow the discussion here:http://groups.google.com/group/google-wave-api/browse_thread/thread/2... ) It would be nice to get some statement on this from a googler. Since Wave is developed using GWT I would like to be able to develop extensions using GWT, as well. Cheers, Jonas -- Jonas Huckesteinhttp://thezukunft.com Hi Jonas, Yes, the iframe (std) linker was the only official primary linker set up to handlecode splitting. I only use that linker and haven't dug too deeply, so I don't know if that was done because of a fundamental problem, for performance/efficiency reasons, or if was just left as an exercise to developers since there wasn't much of a call for it. If it's one of the latter two, it shouldn't be hard to adapt code from the iframe and selectionscript linkers and incorporate it into a version of thexslinker. If you aren't already familiar with it, the key method is doEmitCompilation() in SelectionScriptLinker. CompilationResult artifacts have a String array of the js code associated with that permutation, each entry containing a code fragment. The linker prepares the primary fragment to load correctly, but subsequent fragments are just output directly to a matching subdirectory. http://www.google.com/codesearch/p?hl=en#A1edwVHBClQ/dev/core/src/com.. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to get the row number of a flex table
you can set buttons ID by the method getElement().setId(); you can set Id as row number and as whenever button get clicked you will have to check its id by getElement().getId() which is row number that we had set. -- Aditya On Mon, Jul 5, 2010 at 8:53 AM, Vik vik@gmail.com wrote: Hie I have a table extending a FlexTable.

UIBinder and SmartGWT 2.2 : how to get them working
hi there, does anyone have a comment on what it takes to get UiBinder and SmartGWT 2.2 up and running ? We are using SmartGWT v 2.2 Tree and Grid Controls on top of GWT 2.03. Can someone suggest what techniques can be employed for both to play together ? We saw http://code.google.com/p/uibinding-smartgwt/. Is that the recommended approach ? If someone already has UiBinder working fine with SmartGWT, that would be of great use to us. Any tips/pointers appreciated very much, BR, ~A -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
