Re: GWT menu item text alignment issue
Instead of using setText() from menuitem i have created my own
settext() as below
public void setText(String text, String acceleratorKey) {
Element leftDIV = DOM.createDiv();
DOM.setElementProperty(leftDIV, "align", "left");
DOM.setInnerText(leftDIV, text);
DOM.insertChild(getElement(), leftDIV, 0);
Element rightDIV = DOM.createDiv();
DOM.setElementProperty(rightDIV, "align", "right");
DOM.setInnerText(rightDIV, acceleratorKey);
DOM.insertChild(getElement(), rightDIV, 2);
}
This method shows the menuitems but do not show any effect of
DOM.setElementProperty(leftDIV, "align", "left");
or
DOM.setElementProperty(rightDIV, "align", "right");
output from above code is:
CreateAlt+Ctrl+C
EditShift+E
OptimizeCtrl+O
can anyone help if i can create two div elements so that alignment can
be done properly or is there any otherway to achieve this.

Re: how to debug "java.lang.RuntimeException: Deferred binding failed for..."
" Put the persistence.xml in your source in the correct place."
what does this mean?
the persistence.xml is located in myIncluded.jar/META-INF. And in my
webApp.war it is located in /WEB-INF/lib/myincluded.jar/META-INF. Imho
that's the right place, isn't it?
p.s. sorry for double post, don't know how this could happen

RequestFactory+Service Layer with User ID in the HTTP Header
In our application we have implemented the following
1. User security by extending the RequestFactoryServlet and *overriding
the doPost* method for validating the user session.
2. If the user is logged in the request is proceeded further
3. If the user is not logged in Error is sent back as the response ( Have
*custom RequestTransport* for this as Thomas Broyer suggested in the
groups )
4. Also the user id, session id is added to the HTTP Header in the
*RequestTransport's
configureHeader*.
Now what we would like to do is to use the user id as part of the
RequestContext internally.
For example, to retrieve all the record's for a particular user,
@Service(value = IUserService.class, locator = ServiceLocator.class)
public interface UserRequest extends RequestContext
{
abstract Request>* findRecords(String userId);*
}
The service locator locates the IUserService implementation from the spring
layer. The User service also has the method findRecords(String userID) which
returns List objects.
I am wondering whether, Is it possible to have the method signatures on the
RequestContext as follows,
@Service(value = IUserService.class, locator = ServiceLocator.class)
public interface UserRequest extends RequestContext
{
abstract Request> *findRecords()*;
}
The findRecords() is not taking the user id as the parameter. Is it possible
to add the user id from the session to the server call. I just dont want all
the my RequestContext methods to have "User ID".
I feel this is possible but can't figure it out on my own.
Thanks

math performance
Hi there, We are developing an application which neds to do some heavy calculations on the client side. We are using the Java double type, standard arithmetic operations, plus sqrt and power from math. When I run the app on dev mode, the code runs OK, but when I actually deploy it, the time required to perform the same calculation (on the same host!) jumps to ~90 times of the original. I guess this is because when running in dev mode, the calculations happen in the JVM, and when running in deployed mode, they run in JS space, in the browser. But still, is this expected? Is basic arithmetic in JS this slow? (Tried with both FF3.6 and FF4.0 RC.) What can I do to improve this situation?

Unit Testing RequestFactory with ServiceLocator
We have used EntityLocator and ServiceLocator with our Application's RequestFactory. Now that we want to unit test the implementation, What is the best way to unit test ? I have looked at RequestFactoryMagic which creates InProcessRequestFactory but not quiet sure how that applies to a ServiceLocator approach. Here is my thought. 1. Insert test data in to in memory database 2. Create RequestFactory Instance 3. Call a method on a Request object ( This is where the problem is, If the request is to query a table on the database using the ServiceLocator. it does not work. ) 4. Verify the result.

How to pass objects between modules, in a RPC based service
Hi all, I am working on a project, in which RPC based services are implemented using GWT. This project is to be deployed on GAE. The first module contains UI for login. After a successful login, a session id is created and send back to this module (login module). Immediately after this, I redirect the user to a new page using "Window.Location.assign()". My problem is, that I need to send session id to this new module. Please suggest, how can I accomplish this?

Extending a ClientBundle and using replace-with in gxt.xml
I'd like to change the default css for CellTable in my entire
application. I have a subtype defined like so:
public interface MyCellTableResources extends CellTable.Resources {
interface CellTableStyle extends CellTable.Style {}
@Source({"celltable.css", CellTable.Style.DEFAULT_CSS})
@Override CellTableStyle cellTableStyle();
}
And I'd hope to be able to do something like this in gwt.xml:
I expected that GWT.create(CellTable.Resources.class) would
effectively call GWT.create(MyCellTableResources.class) and get the
implementation. But deferred binding just fails because
MyCellTableResources is not an instantiable type. Isn't it a bit silly
that GWT.create fails here, when the type that it is complaining about
not being able to instantiate is a type that can be GWT.create()ed?
Is there a workaround - maybe some way I can bind to the generated
implementation of MyCellTableResources?

Re: MySQL server in development mode
I use maven. So I put this jar as scope provided that meaning that this jar is provided for the environment where I put the WAR. Now, you doesn't need the jar to compile because you use it at runtime, so you can compile your application without the jar in your classpath. Then delete this jar in the classpath and you don't have problem Juan PD: Sorry my english 2011/3/17 Erel Segal > I did 3 and it worked. > > But I still wonder, do I really have to manually delete this jar > whenever I upload my application to Tomcat?

I don't have the answer, but I believe this will come one day or another, particularly given the Cell widgets and the new orientation they're taking for widgets: http://code.google.com/p/google-web-toolkit/wiki/CellBackedWIdgets The real question (other than "when?") is: will they augment UiBinder, create a new thing, or integrate Closure Templates? > For example, like JSP.

No, SafeHtml is about security, and SafeHtmlTemplates is a templating tool producing SafeHtml and enforcing that "security", because many uses of templates are about putting "external values" into the placeholders (whether the user provided the values, or your got them from the server –you shouldn't trust a server, because you cannot trust the network between the app and your server, so it might actually not be *your* server that responded–). > I don't see any performance reasons not to do a templating > tool. > > > In the case of your "Hello MAX", assuming its part of a bigger "UiBinder > > template", I'd rather put the ui:field on the and use setInnerHtml > or > > setInnerText on it, building the "template" in the code (using Messages > or > > SafeHtmlTemplates) > > In this case It's much more simple and elegant to use a template in > only place than make a lot of redundant code throughout application. > > Using a SafeHtmlTemplates, you'd have a single template in one place, and then use it wherever you need. Note that I was presuming this was only a part of a bigger UiBinder file (one with widgets et al.) Otherwise, of course, you'd only use SafeHtmlTemplates or Messages, without UiBinder (but didn't we agree on that already?) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Where placeholders in uibinder?
UiBinder is not a templating tool, it's a "UI building" tool. If you want templating, use Messages or SafeHtmlTemplates. In the case of your "Hello MAX", assuming its part of a bigger "UiBinder template", I'd rather put the ui:field on the and use setInnerHtml or setInnerText on it, building the "template" in the code (using Messages or SafeHtmlTemplates) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Go with UiBinder. Use InlineLabel and simply call setText.

Where placeholders in uibinder?
Let's assume I need to paste some piece of html in my page: e.g.
Hello, MAX
Where "MAX" is a parameter.
If I would do that in the code I would make the next function:
public String getHtmlTemplate(String parameter){
return "
Hello, " + parameter + "
"
}
But If I would use uibinder I should make the next:
Hello, .
+
declare @UiField SpanElement nameSpan; + call
nameSpan.setInnerText(name).
I think the first approach is simpler, has less code and more
effective(no need extra calls to js object-elements). However, the
first approach is maybe less maintainable.
So, in general I think it's better to do html-template in the source
code than uibinder templates! Why does GWT not handle placeholders? I
don't see any hindrances to implement that for GWT. What do others
think about uibinder?

Every time I change a back end Spring service class, my eclipse project doesn't pick up the changes unless I invoke Eclipse/ Project/clean on my project. I've developed similar projects in the past and don't think I was forced to do this. Assuming that this isn't the way that its supposed to work, does anyone have any ideas what my problem might be?

Re: how to debug "java.lang.RuntimeException: Deferred binding failed for..."
I feel a bit sheepish about it.But the Failure was much simpler then
you all could imagine (obviously):
simply i missed "extends RemoteService" !
but now it seems i got a real problem: the 3rd party class the server
side uses jpa2 as mentioned before. and its code now throws "no
persistence unit found". But the unit exists: in fact this 3rd party
jar is executable and its running fine stand alone (the
persistence.xml is contained in jar file, packed by maven-assembly-
plugin).
so it seems that the access to "persistence.xml" is some how
restricted if the jar is accessed through jetty/myApp? Or why i got
this error only if run via myApp?

Re: Proxy & POST
basically what I have done is adding:
gwt-dev.jar in the client classpath, and adding at the file web.xml:
JettyProxy
org.mortbay.servlet.ProxyServlet$Transparent
ProxyTo
http://localhost:8080/
Prefix
/
1
I used localhost:8080 as proxied url, as my server app runs (in
another jetty) under:
http://localhost:8080/myservapp
anyway this code:
final StringBuilder content = new StringBuilder();
content.append("j_username=" + URL.encode("myusername"));
content.append("&j_password=" + URL.encode("mypasswd"));
final RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST, URL.encode(BASEURL + "/
j_spring_security_check"));
builder.setHeader("Content-Type", "application/x-www-form-
urlencoded");
try {
builder.sendRequest(content.toString(), new
RequestCallback() {
public void onResponseReceived(Request request,
Response response)
{
Window.alert("STATUS : " +
response.getStatusCode());
}
public void onError(Request request, Throwable
exception) {
Window.alert("ERROR");
}
});
} catch (final RequestException e) {
Window.alert(e.getLocalizedMessage());
}
returns always status-code = 0...
any help?
Thanks,
Julio

Re: how to debug "java.lang.RuntimeException: Deferred binding failed for..."
Looks like the Java source for AgsService is not available, but it should be
available by default since it's under the client package. However, if you've
put a source path in your gwt.xml to make another package hierarchy
available to the GWT compiler, you have to explicitly include client , as
well.
WRONG
RIGHT

You said:

Does that jar file contain only .class files? GWT needs the .java
files so it can wave a magic wand over them and translate them to
JavaScript.

how to debug "java.lang.RuntimeException: Deferred binding failed for..."
(this is my last attempt to get a message through the moderators - my
last 2 question seem to be ignored)
at the moment i am working on my first gwt application (after going
through the (great) stockwatcher tutorial). I am facing problem on
getting server side services to work. on starting my app in
development mode i get:

Using Ant 1.7.1 with GWT 2.2 in Eclipse Dev Mode
Hello, I want to use Ant 1.7.1 on the server side for some zip tasks. However, if I start the application from within eclipse using the development mode, there is a conflict between the ant library included within the gwt-dev.jar (as it includes ant 1.8.2) and ant 1.7.1 I want to use. If I deploy my webapp to Tomcat 7, I do not have any problems. Is it possible to override the ant 1.8.2 library from gwt-dev.jar with the ant 1.7.1 library and still be able to use the Eclipse Developement Mode for GWT?

Re: Problem porting a GWT application to a Apache web server on a web hosting service
I think, first, you need to deploy your app to the web container (maybe Tomcat, Jetty, ...) on the hosting server, double check the database parameter (url, port, database name, user, password). Then, check the permission of the user on MySQL database. If any error, please show the stack trace / logs. If everything OK, then now setup the Apache HTTP server.

Master-Detail View & Proxies (GWT 2.2)
Hi everyone, I am building a typical business application that manipulates database tables. Most screens of the application manage one datatype with two different views: - a master view that shows all records of a give type as rows in a table - a detail view that shows all fields for a given entry and allows CRUD operations For most screens I use two different proxy classes for the master and detail views: XMasterProxy extends ValueProxy XDetailsProxy extends EntityProxy The XMasterProxy does not need to be an EntityProxy because it is never sent back to the server. But as it is never mentioned that ValueProxy should be used for this kind of scenario, I wonder if I am not mis-using it. The documentation only mentions embedded objects as a case for ValueProxies. The reason I originally changed the type of XMasterProxy to ValueProxy was that each time I requested a list of XMasterProxy (extends EntityProxy) objects from the server, the RequestFactory servlet requested another copy through the findEntity(Long id) method of my locator. This added a huge payload on the server that now had to handle hundreds of db requests instead of a single one. As this the desired workflow? How can you make this behaviour work in a scenario where several entities are transferred in one go?

Re: One Session(HTTP) for multiple GWT-Modules?
It depends how session management is done on the client. If you use cookies to store the session id it should make no difference as long as you communicate with the same domain (Cookies are domain specific). If you open gmail in two tabs in your browser you won't have to authenticate twice only one time right?. Both gmail instances will share the session. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: MySQL server in development mode
Try this: 1) Verify if you put the mysql-connector-java-5.1.15-bin.jar in correct place. See http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html. 2) What version of mysql you use? Is the driver for this version? If yes perhaps the jar is corrupt. Try download it again 3) Delete mysql-connector-java-5.1.15-bin.jar from WEB-INF/lib/ if you have in your war.

Re: MySQL server in development mode
OK, the problem with Tomcat was solved when I deleted mysql-connector- java-5.1.15-bin.jar from WEB-INF/lib under webapps. It probably should be only in the Tomcat lib. Very strange, as it means I cannot just copy my project and paste it into webapps.

Proxy & POST
Hi, I'm using GWT 2.1.1 and in my app there is a RequestBuilder/POST to a different url respect to the client (basically client in dev mode against 8080 localhost server). The POST fails cos of the "XSS" from Firefox. I followed suggestions here: http://code.google.com/p/google-web-toolkit/issues/detail?id=3131#c46 without any luck and as I'm stuck on the same problem since days(!) I'm asking you is someone has got a working configuration/solution for this problem.

Re: How to call existing javascript functions (without arguments) in GWT?
on your EntryPoint:
public void onModuleLoad() {
..
test();
}
private native void test() /*-{
$wnd.testFunction();
}-*/;
or if you want extra time defer it
Scheduler.get().scheduleDeferred(new Command() {
public void execute() {
test();
}
});

Re: Problem porting a GWT application to a Apache web server on a web hosting service
Thanks for the reply. If my web hosting service does not provide Java application server like TomCat, should I be able to install one in the subdomain in the web hosting site or should the web hosting service owners do it?

Re: How to call existing javascript functions (without arguments) in GWT?
It's easy for the 1st question:
addSymbolButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
test();
}
});
private native void test() /*-{
$wnd.testFunction();
}-*/;
where testFunction is the existing javascript function.
I still don't know the answer for the 2nd question which is: how to call an
existing javascript function when GWT finishes its job when a page is
loaded?

Re: Problem porting a GWT application to a Apache web server on a web hosting service
Hi, You need a Java application server like Tomcat (or Jetty or Glassfish, etc.) to run Java. Apache (httpd) alone can't run your java code.

How to call existing javascript functions (without arguments) in GWT?
Hi All,
addSymbolButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
// How to call a javascript function, e.g. buttonClick(),
here?
}
});
and how to call an existing javascript function after GWT finishes
everything on a page? Let me explain it in another way: for example my
page is like this:
http://www.w3.org/
TR/html4/strict.dtd">
I think in MName.nocache.js GWT will catch the onLoad event of the
body or the DOM ready event. What I want is to execute a javascript
function (without arguments) after GWT finishes its job in the body's
onLoad event handler or DOM-ready event handler.
Thank you.

Constant turned into unclobberable portion by I18N.
Hi everyone.
Please look at the below simple UiBinder using a constant:
At we strive
for our customers.
The cons.businessName gets translated properly according to the
'localed' MyCons.properties that are provided:
MyCons.properties
MyCons_fr.properties
MyCons_es.properties
... etc.
But when I18N gets into the game I can't manage to get the constant
internationalized anymore:
At we
strive for our customers.
As soon as I surround the translatable text with the tags it
gets indeed translated according to the various
*GenMessages.properties files but then the previous tag becomes an
unclobberable portion (see
http://code.google.com/webtoolkit/doc/trunk/DevGuideUiBinderI18n.html#Messages_with_unclobberable_portions.)
Here is how the generated *GenMessages.properties looks like:
B572CBEE8B7279CC8CC18CCFA9B9DCE1=At {0}{1} we strive for our
customers.
Does anyone have any idea how to get, on the one side, constants
translated properly according to the various MyCons.properties files
and the other parts of the text, on the other side, translated
according to the various *GenMessages.properties files?
Thank you.
Luc

New project - serialization for gears workers
We hacked GWT compiling/linking process and RPC serialization so that it is possible to write workers in Java and have DTOs only in Java. http://code.google.com/p/gj-workers/ We believe that this code actually belongs to GWT-gears library and we would really like to see this code merged there. If you are owner or contributor of GWT-gears and are interested in doing this, please contact me. We made this code available as a separate project, so that everyone has a chance to evaluate its usability. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Problem porting a GWT application to a Apache web server on a web hosting service
I have developed a GWT application which connects to a MySQL database and returns some value. My application runs fine on a Apache Tomcat server on my computer (with Windows XP Professional). However, I have problems running it when I port it to a web hosting service with a Apache server on Linux OS and a MySQL database. I recreate my table in the database in the web hosting site and make appropriate changes to my GWT files (for accessing the database) and then, transport them. I can see only the main HTML page and I think the java source code is not running at all because I cannot see the output of the Java client- side code. What can be going wrong? Can some one give me the exact steps of porting a GWT application accessing a MySQL database to a web hosting service? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: MySQL server in development mode
It doesn't work at Tomcat either, but I don't know if the problems are related. This is what I did regarding Tomcat: * I put the file "mysql-connector-java-5.1.15-bin.jar" in Tomcat's lib/ folder; * I edited the file conf/context.xml to declare a resource: WEB-INF/web.xml * I edited my application's web.xml file to declare a resource: chatroom gwtchat.server.ChatRoomServiceImpl chatroom /gwtchat/chatroom chatroom /wizardofoz/chatroom DB Connection jdbc/TestDB javax.sql.DataSource Container * I restarted Tomcat. Now, in the Tomcat log file, I get the following exception: "No suitable driver found for jdbc:mysql://localhost:3306/gwtchat?..."
