Re: Unit testing classes that depends on RequestFactory
I'm pretty new to RF but by reading through various posts regarding
the testing of RF i came up with the following solution that seems to
work well so far with spring
First an abstract test case that your unit test would extends
@TransactionConfiguration(defaultRollback = false)
@ContextConfiguration({ "classpath:spring/somecontext.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public abstract class SpringRequestFactoryServletTest{
@Autowired
SpringRequestFactoryServlet springRequestFactoryServlet;
protected MockServletConfig servletConfig = new
MockServletConfig();
protected MockServletContext servletContext = new
MockServletContext();
protected T requestFactory;
private SpringRequestTransport transport;
private final Class requestFactoryClass;
public SpringRequestFactoryServletTest(Class
requestFactoryClass) {
this.requestFactoryClass = requestFactoryClass;
}
@Before
public void init() {
requestFactory = create(requestFactoryClass);
springRequestFactoryServlet.setServletConfig(servletConfig);
springRequestFactoryServlet.setServletContext(servletContext);
String[] contexts = new String[] { "classpath:spring/
somecontext.xml" };
XmlWebApplicationContext webApplicationContext = new
XmlWebApplicationContext();
webApplicationContext.setConfigLocations(contexts);
webApplicationContext.setServletContext(servletContext);
webApplicationContext.refresh();
servletContext.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,
webApplicationContext);
}
private T create(Class requestFactoryClass) {
T t = RequestFactorySource.create(requestFactoryClass);
transport = new SpringRequestTransport(springRequestFactoryServlet);
t.initialize(new SimpleEventBus(), transport);
return t;
}
/**
* Allows firing a Request synchronously. In case of success, the
result is
* returned. Otherwise, a {@link RuntimeException} containing the
server
* error message is thrown.
*/
public T fire(Request request) {
return fire(request, null);
}
public T fire(Request request, String loginname) {
ReceiverCaptor receiver = new ReceiverCaptor();
MockHttpServletRequest httpRequest = new MockHttpServletRequest();
MockHttpServletResponse httpResponse = new MockHttpServletResponse();
transport.setRequest(httpRequest);
transport.setResponse(httpResponse);
if(loginname != null) {
httpRequest.setUserPrincipal(new PrincipalMock(loginname));
}
request.fire(receiver);
handleFailure(receiver.getServerFailure());
return receiver.getResponse();
}
private void handleFailure(ServerFailure failure) {
if (failure != null) {
throw new RuntimeException(buildMessage(failure));
}
}
private String buildMessage(ServerFailure failure) {
StringBuilder result = new StringBuilder();
result.append("Server Error. Type: ");
result.append(failure.getExceptionType());
result.append(" Message: ");
result.append(failure.getMessage());
result.append(" StackTrace: ");
result.append(failure.getStackTraceString());
return result.toString();
}
}
The SpringRequestTransport looks like this
public class SpringRequestTransport implements RequestTransport {
private final SpringRequestFactoryServlet requestFactoryServlet;
private MockHttpServletRequest request;
private MockHttpServletResponse response;
public SpringRequestTransport(SpringRequestFactoryServlet
requestFactoryServlet) {
this.requestFactoryServlet = requestFactoryServlet;
}
public void setRequest(MockHttpServletRequest request) {
this.request = request;
}
public void setResponse(MockHttpServletResponse response) {
this.response = response;
}
@Override
public void send(String payload, TransportReceiver receiver) {
try {
request.setContentType("application/json");
request.setCharacterEncoding("UTF-8");
request.setContent(payload.getBytes());
requestFactoryServlet.handleRequest(request, response);
String contentAsString = response.getContentAsString();
receiver.onTransportSuccess(contentAsString);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
The SpringRequestFactoryServlet
@Controller
@Transactional
public class SpringRequestFactoryServlet extends RequestFactoryServlet
implements ServletContextAware, ServletConfigAware{
private static final ThreadLocal perThreadContext
=
new ThreadLocal();
private ServletContext servletContext;
private ServletConfig servletConfig;
public SpringRequestFactoryServlet() {
super(new DefaultExceptionHandler(), new
Spri
Re: Requestfactory : best practice for persisting updates with Locator
Perhaps a small test case might better explain what problem i'm facing
with the delta's send from request factory to the locator class (the
fire() method is in order to do synchronous testing of the requests
sent)
@Test
public void testPersistAndUpdate() throws Exception {
SomeRequestContext addRequest = requestFactory.someRequest();
FooProxy fooProxyCreated = addRequest.create(FooProxy.class);
fooProxyCreated.setName("fooname");
BarProxy barProxy = addRequest.create(BarProxy.class);
barProxy.setName("barname");
fooProxyCreated.setBars(Arrays.asList(barProxy));
IntegerResponseProxy addResponse =
fire(addRequest.persist(fooProxyCreated));
assertEquals(null, addResponse.getErrormessage());
assertNotNull(addResponse.getValue());
Integer id = addResponse.getValue();
SomeRequestContext findRequest = requestFactory.someRequest();
FooProxy fooProxyFound = fire(findRequest.find(id).with("bars"));
SomeRequestContext updateRequest = requestFactory.someRequest();
fooProxyFound = updateRequest.edit(fooProxyFound);
BarProxy bar = fooProxyFound.getBars().get(0);
bar.setName("newname");
IntegerResponseProxy updateResponse =
fire(updateRequest.persist(fooProxyFound));
assertEquals(null, updateResponse.getErrormessage());
assertEquals(id, updateResponse.getValue());
}
So on the server the service method just looks like this
public IntegerResponse persist(Foo foo)
and the
public class Foo{
Integer id;
String name;
List bars;
|
and Bar might have a composite id
public class Bar {
BarPK barPK;
}
public class BarPK{
Integer fooId;
String name;
}
When it is created all properties gets sent to the persist() method
and the full object can easily be persisted using hibernate. The
second time an update is occuring on that object the fooId will be
null as no changes have been made to that on the client evidently.
This makes working with the Foo foo object in the persist method quite
manual. And how would i differentiate if some null property is just
not sent because no update has occured or because it has been reset to
null? Is such a use case not supported by RF and i have to stick with
RPC?
Thanks for any hints
Dominik

Requestfactory : best practice for persisting updates with Locator
Hi, I finally did a first try at RF and am wondering what is the best way to implement the persist method on a Locator class in order to deal with only the deltas send from the client? As right now my persist(T objectToPersist) method on the Locator is doing a create if the object has no id associated to it. This use case is pretty similar to what i would have done with RPC as the whole object is being sent evidently. But when i then reload the object from the server, change some properties on it and call persist again a pretty 'light' objectToPersist appears in that method which seems to even have lost the PK on the associations in that object. So am i missing something or is there a good way to implement those updates especially when dealing with associations in that object?

Re: OOPHM memory leak?
Thanks kozura for your reply, here with me I see an increase of around 40 MB on each reload, and my app already starts with java allocating 200 MB on the first load. Not sure if the project size correlates with the amount of memory that leaks, here with me I have around 700 classes on my project? Also not sure what eclipse is doing in the background and perhaps is holding the threads until garbage collecting them, but I see 3 new threads added each time when i relaunch the application. Thanks again for your information Dominik Same setup, I do see a slow increase of about 10-20MB per page upload in the Developer application. Eventually this might lead to out of memory exception; you could always increase the heap size for now to avoid that for awhile longer, -Xmx512 or whatever. I see nothing maintained in the app that should be causing extra memory to be take for each reload, so seems there may be a legitimate memory leak here. I don't see the consistent thread increase, although it does seem to go up by one occasionally on restart. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

OOPHM memory leak?
Hi there, I'm using eclipse 3.5 on Mac OSX with the google eclipse plugin and GWT 2.0. What I see is that every time I reload my gwt app that I'm debugging using the Web Application launch configuration from the plugin and OOPHM in Firefox 3.5, the memory usage of the java process that is being started when i start the Web Application via OOPHM is constantly rising until reaching 400 MB where i get an OutOfMemory exception. Basically I can thus only 4 or 5 times reload the web page until having to close the Web Application from within eclipse and start a new one. Besides that I'm seeing that everytime I launch a new Web Application (having terminated the prior one) the threads in my eclipse process is steadily rising too, so that after a while i get like > 150 threads which is bring down my eclipse performance. I really like the way OOPHM works, but did someone else experiment the same performance/memory problems while using it?

Re: Alternative for Class.isAssignableFrom() ?
@Chris, yes, thanks for the tip, I already tried that by getSuperclass() will not get any classes that are implemented by this class but only a superclass. So I would not be able to use interfaces but only extend from a base class to which i could also attach a listener too and that would be triggered if a subclass event would be fired, but that's not the same than having the power and flexibility of interfaces. @Nathan, your solution is what I tried first and my junit tests would run just fine with this but GWT doesn't implement the isAssignableFrom() method, so that's why I'm looking for some alternatives if there are? Thanks again for your great help and perhaps there are other solutions out there still? Dominik The JRE Emulation Reference says, that getSuperclass() is supported. http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html Maybe you can make do with this?

Re: MVP - interface that implements setVisible()
Hi Davis,
thanks for the fast reply.
That is actually a good idea, I was always looking for getters to
implement on the Display, never occured to me that simple methods that
go the other way might be as efficient too.
Thanks again for your help.
Dominik
Hi Dominik, why not have a display interface like this?
interface Display {
void toggleVisible(boolean toggle);
}
If you need the presenter to toggle specific widgets on the display
create an enum:
interface Display {
enum WidgetType {
BUTTON,
TEXTBOX
};
void toggleVisible(boolean toggle, WidgetType type);
}

Re: com.google.gwt.junit.client.TimeoutException: The browser did not contact the server within 60000ms.
I haven't tried the UiBinder yet, but if i remember right I read
somewhere that it is now prefered to use HtmlUnit tests instead of
using the GWTTestCase.

Re: How do I get the current position of a widget within a Absolute Panel?
Hi,
did you try to use the getAbsoluteLeft() or getAbsoluteTop() methods
of the widget class?
So you could query those for the child widget and for the absolute
panel and simply substract both in order to get the relative position
of the widget inside the panel.
also if the widget is a direct child of the absolute panel you might
want to have a look at
/**
* Gets the position of the left outer border edge of the widget
relative to
* the left outer border edge of the panel.
*
* @param w the widget whose position is to be retrieved
* @return the widget's left position
*/
public int getWidgetLeft(Widget w) {

Re: Horizontal Panel isn't displaying
Hi Brendan,
for such problems I would recommend using GWT 2.0 and the OOPHM so
that you can debug your application from within FF for example and use
FireBug to inspect your HorizontalPanel (which will be a in
the DOM) and look with Firebug why the anchors are not visible in it.
(which could be then a css problem or something)

Re: GWT PHP HTML 5 interaction
Hi,
to be honest I'm no php guy, so I'm not sure about the implementation
details of the hessian control on php side.
on gwt side you simply implement an interface, for example like this
public interface HelpHessianService {
public List getHelpTopics(String search);
}
and you then instantiate this interface via a helper method
import com.caucho.hessian.client.HessianProxyFactory;
String hostUrl = getHostUrl(request);
String url = hostUrl + "/index.php?
main_page=gwt_handler&hessian=true";
HessianProxyFactory factory = new HessianProxyFactory();
HelpHessianService helpHessianService =
factory.create(HelpHessianService.class, url);
and then you can just call helpHessianService.getHelpTopics(search);

Re: Announcing GWT 2.0 Milestone 1
Hi Jospeh,
did you consider to install the Google Plugin for eclipse?
You will even then run into problems, but reading through this post
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/527518f17e7a484e/28e2bbd2786143f3
you should be up and running pretty soon.

Re: OOPHM GWT 2.0 Milestone 1 on Mac
Hi Christian, I moved to the ms1 yesterday but had been playing around with OOPHM with a version that i built from the trunk before and also got into problems when FF 3.5 came out and broke the OOPHM mode that i was using. Now yesterday with the ms1 release and the plugin already installed i tried to connect to the url that the OOPHM gave me but it always told me that there was no plugin available. I first tried to deactivate the plugin and reinstall it, but with no luck. So what I did was to remove the plugin from FF 3.5 first and then reinstall it from the link that the "no plugin available" page gave me. After that the OOPHM is now working fine.

Re: GWT Performance issue in IE browser.
pal, you could try using IE8 and the profiler it is shipping with to determine which methods are being called (compiling your code first with -pretty) and which one take more time than others. In our project we thus found out that IE was behaving bad on equals() and equalsIgnoreCase() methods which we replaced then by using hashmaps.

Thanks Chris for the link, as described in the link just copying gwt-dev.jar and renaming it to gwt-dev-mac.jar tricks the eclipse plugin and let's you easily start the OOPHM mode.

Re: Announcing GWT 2.0 Milestone 1
Congratulations! That was way faster than I expected, thanks for getting this release out that early. One remark: seems like the eclipse plugin is not accepting the current release with the message after selecting the gwt-dev-ms1 folder that gwt-dev-mac.jar (in my case) is missing. So I guess that a new eclipse plugin version will have to handle that accordingly.

Re: Hosted Mode very slow on Mac
i'm running gwt with eclipse and on osx leopard too and haven't had any problems with it for years, so i would guess that the problem will be hidden somewhere in your code. You might try to uncomment temporarily parts of your code that you could think problematic and see if that fixes it and thus being able to track down the exact point that is causing that problem.

Re: How to initiate a event inside a KeyPressHandler
you could do something like this
public void onModuleLoad() {
// Create a tab panel with three tabs, each of which
displays a
different
// piece of text. VerticalPanel
formSelectPanel = new VerticalPanel();
formSelectPanel.setSize("150px", "400px");
final TextBox formFilterBox = new TextBox();
formFilterBox.setFocus(true);
formFilterBox.setSize("150px", "20px");
formFilterBox.addKeyPressHandler(new KeyPressHandler
(){
@Override
public void onKeyPress(KeyPressEvent event) {
int index = 0;
//implement some logic to set index according to key pressed
formFilterBox.setSelectedIndex(int index); });
formFilterBox.addChangeHandler(handler)
ListBox formList = new ListBox(false);
formList.setVisibleItemCount(10);
for ( int i = 0; i < 40; i++){
formList.addItem("form"+i);
}
formList.setSize("150px", "380px");
formSelectPanel.add(formFilterBox);
formSelectPanel.add(formList);
RootPanel.get().add(formSelectPanel);
}
I haven't tested the code, you might need to adapt the syntax, but i
hope that you get going like this

Re: Character.isWhitespace alternative? (whitespace check)
Hi Ed, for performance reason I would definitely recommend you to actually use regex instead of equals or equalsIgnoreCase methods of the String class.

Hi Henrique, I know that if you would use RPC you could be canceling the com.google.gwt.http.client.Request.cancel(); but as you have to upload a file and using a FormPanel probably I don't see any other way than handling the canceling on GWT side, ie set a variable isCanceled = true and when the form returns handle according to that variable any further action in order to rollback the action.

Re: Cookies and RPC
Hi Tom,
not sure I understand your cookie question, but in GWT you can query
for cookies using the class
com.google.gwt.user.client.Cookie
and there have a look at the method
/**
* Gets the cookie associated with the given name.
*
* @param name the name of the cookie to be retrieved
* @return the cookie's value, or null if the cookie
doesn't exist
*/
public static String getCookie(String name)
So in your GWT code you would check if a cookie exists like this
String cookie = Cookie.getCookie(myCookieName);
if(cookie != null){
// cookie exists
}

Re: GWT performance
To add my two cents here too, for our large GWT app we found out that IE especially was getting slow because we had a lot of equalsIgnoreCase () method called in our controllers that checked for property changes of the model objects. Changing this to equals() already helped a bit, and using maps instead was getting the performance back to what it was in the other browsers.

Hi Vruddhi, I would suggest trying to do setting the background color of a button from within a CSS file and just set a classname from within GWT.

Re: GWT testing without GWTTestCase and the DOM
Hi Eugen, I would recommend you to read this post http://robvanmaris.jteam.nl/2008/03/09/test-driven-development-for-gwt-ui-code/ There's currently also the MVP (not MVC) design approach being discussed on this forum, you might also be able to use that for testing with normal Junit tests and not GWT tests.

Page flickering on FF 3.5
Hi there,
we have a web app based on GWT that you can see at
http://beta.homeprodigy.com/index.php?main_page=map
this page is now flickering when you load it with FF 3.5. On FF 3.0 it
was working fine.
My only guess is that it might have to do something with
DeferredCommand.addCommand(new Command(){
public void execute() {
as we add the main UI components to the RootPanel using above commands
in order to break those tasks into smaller ones. As the page is
flickering while those elements are added my assumption goes into that
direction.
Anybody has run into similar problems?
Thanks for any answers in advance.
Dominik

Re: Regex issue with IE
Hi davis,
I'm using the following regex to match addresses in the format of 123
west road
public static final String ADDRESS_REGEX =
"[0-9]+\\s*\\D+";
and it works fine on IE too. Note the double slash before s and D
So I don't think that the double slash is the problem.

a print killer for IE?
Hi there, I have the feeling that the tag that is used on IE7/IE8 for the image bundle I guess is breaking printing of GWT pages on IE. I also have the feeling as that tag is new, that means we moved to gwt 1.7 recently and that is when I first saw that tag and when printing stopped working. What I had to do was to parse the whole html and remove those gwt:clipper tags and all their content. Then printing in IE worked again. Anybody with some similar experience or thoughts out there?

Real estate website using GWT
Hi there, right now we are building a leading real estate website for all of Northern Texas which is using GWT to first include some components on php side as you can see at www.homeprodigy.com where the search box on the top right is fully built with GWT. And we have a 100% GWT part of the website, a dynamic map which filters over 6 properties at real time to the many filters that you can set and displays all of them on the map even when you are way zoomed out at www.homeprodigy.com/index.php?main_page=map I think that GWT is really a great technology, most of all being able to debug the code in the GWT Shell, the pain it takes from having to deal with the DOM and different browsers. What we learned during this project and having for the dynamic map already quite a huge application is the extensive of LazyWidget in order to instantiate the widgets only when they are needed. Especially for IE we had performance problems because of extensive equals() or equalsIgnoreCase () methods which we switched to the use of hashmaps. Items that we are looking for would certainly be OOPHM and the possibility to set points in the code so that the GWT code could be loaded lazily and thus speeding up load time of our application. Thanks for this great product and keep on with the great work! Dominik --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Memory Leak in IE7
I can recommend to everybody with performance problems on IE6 or IE7 to download IE8 and use it's javascript profiler in order to check your js calls and time they take in order to see bottlenecks. For example I found out that in my code (a big application) a lot of equalsIgnoreCase() calls were made that slowed down IE7 dramatically. I refactored the code where possible to even avoid having to use equals () by simply using maps to store the data which was way faster.

Re: Load gwt module before image are loaded on IE7
Thanks for all your responses, at the end we didn't change anything because the image provider fixed the problem on his side and now images are loading fast as before. But I think that the loading image from within gwt would have been a feasable solution. Dominik On 15 Apr., 10:26, Vitali Lovich wrote: > Try putting your
Re: Load gwt module before image are loaded on IE7
Ok, i must have understand something wrong then, but from the wiki i read the last four sequences as following 9. ...cache.js completes. onModuleLoad() is not called yet, as we're still waiting on externalScriptOne.js to complete before the document is considered 'ready'. 10. externalScriptOne.js completes. The document is ready, so onModuleLoad() fires. 11. reallyBigImageTwo.jpg completes. 12. body.onload() fires, in this case showing an alert() box. So as described in the wiki the onModuleLoad will fire once the last js script is loaded, but before the reallyBigImageTwo is loaded. This applies to all normal browsers it seems except IE...

Re: Load gwt module before image are loaded on IE7
Thanks Salvador for pointing out the interesting link above. I read through it and I must admit that I found an error in it, namely exactly my problem on IE7, that the will block on IE7 the firing of the onModuleLoad() event in GWT until the image has finished loading. I will post back once I implement a working solution.

Re: Load gwt module before image are loaded on IE7
Thanks for your answers. Ok, i can see the javascript solution, in our case a php backend would rewrite the html and add unique ids to the divs where the images will be added and call a JSNI method that will be triggered on gwt module load and pass the image urls to that method in an array or something. Any other possible solutions out there? Thanks for the input. Dominik On 14 Apr., 18:16, Vitali Lovich wrote: > A browser will fetch all resources from a page before executing any > Javascript.

Re: Load gwt module before image are loaded on IE7
Thanks Jeff for your response, the problem is that the images are within the html page and the gwt module is just a component that has to be included into that html page. So what i would need would be a way that the onModule() method of that gwt component is triggered without having to wait that the images from the html host page finish loading.

Load gwt module before image are loaded on IE7
Hi, I have a page that contains a lot of images and some of those images take a long time to load (in total like 1 min) I have searched the forum and found this similar post http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/d0f0f71ebfd74f0/ff7cc59bd0cb3447?lnk=gst&q=ie7+images+load#ff7cc59bd0cb3447 but with no concrete solution to the problem, that IE7 will wait until all the images are loaded until it will then load the GWT module. Is there a work around for this so that the gwt module will be loaded before the images have finished loading?

Re: StackOverflowError with OOPHM GWTCompiler
I get the same StackOverflowError but on a version build from the 1.5.2 trunk on the 30th of September. I also have a big application and I get that error when i'm launching the GWT shell and then try to Compile/Browse. (on Windows XP SP2) On a mac leopard machine with the same build for mac I don't get this error. I understand that we are on the bloody edge when building from gwt trunk but perhaps some GWT guys have an estimate on when a new release is due?

Re: Invalid version number "null" when using the hosted mode
Ok, i have something to add here too. I had the same issue and my maven build was using the correct new gwt vars, but i wasn't able to connect to a remote url as i was before moving to gwt 1.5.2. What helped for me was to load the hosted.html url directly in the gwt shell, so something like this http://urlToConnectTo:8080//hosted.html (the same url loaded into a browser did show that it was using the "1.5" string, so that it was the correct one) And then at least here on Mac i could make a right mouse click on the page and select Element-Information which brought up the source code of the hosted html page, where i could see that the "1.5" was missing and thus the GWT shell was still loading a stale one. So i had to make another right mouse click on the GWT shell and select "Reload" which then after again inspecting the source code brought up the correct hosted.html page with the correct "1.5" string. After this reload of the hosted.html I could connect to the remote url without problems. So it seems that the GWT shell is doing some caching that could only be fixed like this.
