OutOfMemoryError with lots of unit tests

[Swanthe Lindgren]

Hello
Has someone got any good tips about performing lots of render tests? We 
are using TestNG and maven/surefire test runner which results in 
OutOfMemoryError for our about 500 tests, where each test tries to 
render a page or panel. After a bit of redesigning our test classes and 
call WicketTester.destroy()  after each test, we were able to run about 
50 more tests, but now we are back at OutOfMemoryError.

Try this as args:

-Xms356m
-Xmx1024m
-XX:MaxPermSize=356m
-XX:HeapDumpPath=c:/temp
-Xss1024k


Also you can reuse Application instance etc.

Hi,

Try something like this:

org.apache.maven.plugins
maven-surefire-plugin
true

false
once
-Xmx512m -XX:MaxPermSize=256m



maybe check out the perTest forkMode.

Re: How do you create a toolbar of buttons for a datatabe?

[vov]

Look to DefaultDataTable addBottomToolbar(new NoRecordsToolbar(this));
You can append custom Bottom Toolbar to your table instead NoRecordsToolbar:

public class MyBottomToolbar extends AbstractToolbar
{
  public MyBottomToolbar(DataTable table)
  {
super(table);

RepeatingView headers = new RepeatingView("bottoms");
add(headers);

final IColumn[] columns = table.getColumns();
for (final IColumn column : columns)
{
  WebMarkupContainer item = new
WebMarkupContainer(headers.newChildId());
  headers.add(item);

  WebMarkupContainer header = new WebMarkupContainer("bottom");
  item.add(header);
  item.setRenderBodyOnly(true);
  header.add(new Button("button", new Model("asdf")));
}
  }
}









in your DateTable constructor addBottomToolbar(new MyBottomToolbar(this));

Also you can create custom Column class for getting uniques property for
every Button(for example instead new Button you will call
column.getButtom())

TagTester after Ajax

[Wolfgang]

TagTester works on the content of the last response which, in case of an Ajax
response, is not the whole page but only a small snippet. Even worse, this
snippet doesn't contain the wicket:ids anymore I use for testing.

Is there a way to Ajax-enable TagTester such that...
...you can use TagTester after Ajax refreshes without bothering about this
fact?
...you can use wicket:id attributes to evaluate the result?

It is because I want to test certain Ajax-relevant features that cannot be
tested using the component-based assert... methods on WicketTester and that
cannot be tested if Ajax is disabled.

I know it is a certain additional work for Wicket to enable that kind of
testing because, from the technical point of view, the required document is
not naturally available. However, since Wicket defines its own Ajax engine
it should be able to mock this one such that the Ajax responses are
incorporated in the document and the result can be evaluated as a whole.

Announcing WicketObjects v0.1

[Dan Haywood]

Hi all,

I'd like to announce a new open source (ASLv2) project to help develop 
Wicket applications - Wicket Objects.  This is an integration between 
Wicket and the Naked Objects framework.  The idea is that you can 
develop full webapps just by writing domain objects pojos, and Wicket 
Objects (with a little help from NOF) then renders your objects 
automatically.  You can then use your Wicket skills to customize the UI 
as need be.


There's some screenshots and a quick start on my blog 
(http://danhaywood.com) and there's a website too 
(http://wicketobjects.sourceforge.net).  To get started all you'll need 
is SVN and MVN.


I'm looking for feedback, and I'm also hoping that some of you smart web 
UI guys (not my strongest suit!) might be interested in helping me 
develop it up to a v1.0 release.


Thanks for reading,

Cheers
Dan Haywood

Reading cookies on first/each request

[Bilgin Ibryam]

Hi all,

I want to implement "Remember me" functionality  by storing the encrypted
and base64 encoded username in a cookie.
Then I'd like to check for the cookie on the very first request (or every
request) to the application.

Any tips whats the best way to access httpRequest object on each request to
the application? I suppose it has to do something with RequestCycle object,
but not sure.


Thanks in advance
Bilgin Ibryam

regarding IModel's

[Marzia Forli]

I have a problem with IModel's... Right now I am doing my homework with 'Wicket 
In Action' and I know that models are connections to a data...
What I need to know if there is some kind of design pattern/advice about 
handling the models...
For example there are some typical scenarios that appear in the apps'
1) login form with some ILoginService which have: login (String username, 
String password) and returns User. Would I have to have user and password 
Strings as Form attributes or something else ?
2) user profile data which are in db
3) detail of shopping cart
Are there some guidelines regarding the models and how and where to place them 
and in general what are you guys do... Thanks...

Jwicket and Wiquery

[Josh Kamau]

Hi team;

Whats the difference between jwicket and wiquery? I have already read
wiquery tutorials and seen some examples, but i dont need to find any for
jwicket. any help from jwicket team will do

Kind regards.

Re: Reading cookies on first/each request

[M. Hammer]

Quoting Bilgin Ibryam :

I want to implement "Remember me" functionality  by storing the encrypted
and base64 encoded username in a cookie.
Then I'd like to check for the cookie on the very first request (or every
request) to the application.

Hi,

I do this in the newSession() method of my Application subclass. This  
method is called for the first request of a user, and possible for  
subsequent requests if the requested page is stateless. If a cookie is  
found, I copy the contents to the user's session and use it from there.
You have to cast Request and Response to WebRequest and WebResponse,  
and you can use getCookie() and addCookie(), respectively.


Regards,
  Moritz

There is no tutorial for jWicket yet. Take a look at the javadocs or look into

AW: Jwicket and Wiquery

[Stefan Lindner]

Hi Josh,

yes, jWicket does it the Wicket way.
Generally you have a Behavior (e.g. DraggabeBehavior) extending wicket's 
AjaxBehavior.

The you have some own component (a Panel e.g.)

Now you simply do

myPanel.add(new DraggableBehavior(...));

And DraggableBehavior let's you override some callbacks e.g.

DraggabeBehavior draggable = new DraggabeBehavior() {
onDragStop(final AjaxRequestTarget target, final SpecialKeys 
specialKeys) {
// react when dragging has stopped
}
};
Draggable.setWantOnDragStopNotification(true);


class MyPanel  extends Panel implements IDraggable { // only implements 
IDraggable if you need to react here
onDragStop(final AjaxRequestTarget target, final SpecialKeys 
specialKeys) {
// or react here when dragging has stopped
}
}

MyPanel myPanel = new MyPanel();
myPanel.add(draggable);

That's all.

Stefan

Upgrade wicketstuff-push to Cometd2

[Martin Grigorov]

Hi,

Last weekend I felt a bit bored and I decided to take a look at one of
the cool wicketstuff projects that I had on my list for quite some time
- wicketstuff-core/push-parent. Few minutes later I decided to upgrade
it to Cometd version 2.0.0.RC1 because this is how I understand how the
things work - by debugging them.

And the outcome is: http://github.com/martin-g/wicket-cometd2
It is almost the same as the original code:
- upgrade Maven dependencies
- upgrade it to the new API (just the Java part for now)
- code formatting

Next steps are:
- upgrade Dojo to its latest stable (+ dojox.cometd)
- add implementation with jquery.cometd
- upgrade Wicket to 1.5-SNAPSHOT

At the end I will probably merge it back to wicketstuff-core if the
other developers/maintainers are OK with that.
Until then don't hesitate to fork it or comment here or in github.

Cheers
martin-g

Something like this can be done with a regular Model for each of the Strings
- the default implementation of IModel.  It simply holds a serializable
value.  Or, you can have two String properties in your SignInForm class
(which is probably a panel containing a form), and then give the TextFields
each an instance of PropertyModel that connects it to those properties on
the form class.

A LoadableDetachableModel should be in charge of loading these domain
objects from the database.


> 3) detail of shopping cart

Again, probably a LoadableDetachableModel.  It depends on where you're
storing it.  You will likely store this in the Session (remember that the
session is not thread safe by default).  But, you may be storing it to the
DB so that it outlives the session.  Your call.

perTest is deprecated I think, you should use "always" - although it adds

including wicket component into jsp

[rikizz]

Hi all,

I know the many posts have been written on the same problem, but I have been
looking at the answers for 5 hours without having a simple example to work
with..
I basically need to include a single component (a menu) into my jsp pages,
because we are migrating the application from struts/jsp to wicket.
I tried with the following code but it didn't work:

WICKET APPLICATION:

public class WicketApplication extends WebApplication
{
public WicketApplication(){}
public Class getHomePage(){   return HomePage.class;}
@Override
protected void init(){
getMarkupSettings().setStripWicketTags(true);

getRequestCycleSettings().setRenderStrategy(IRequestCycleSettings.ONE_PASS_RENDER);
}
}


PAGE MARKUP:
http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";
>
  
Wicket Quickstart Archetype Homepage


Wicket Quickstart Archetype Homepage

message will be here



PAGE CODE:

public class HomePage extends WebPage {
public HomePage(final PageParameters parameters) {
add(new Label("message", "If you see this message wicket is properly
configured and running"));
}
@Override
protected void onRender(final MarkupStream markupStream){
System.out.println("RENDER OF THE PAGE!!");
}
}

JSP PAGE:


WEB.XML:



wicket.embedwicket
embedwicket.WicketMenuFilter

applicationClassName
embedwicket.WicketApplication



 
  wicket.embedwicket
/wic/*
INCLUDE
REQUEST
FORWARD
 



WicketMenuFilter:
THIS IS MY CUSTOM WICKET FILTER TO MANAGE INCLUDE URI, AS IT WAS SUGGESTED
BY A GUY HERE:
http://apache-wicket.1842946.n4.nabble.com/embedding-Wicket-into-JSP-td1867715.html
http://apache-wicket.1842946.n4.nabble.com/embedding-Wicket-into-JSP-td1867715.html
 

Basically I overrided the method
public String getRelativePath(HttpServletRequest request)

buy copying it and replacing the following lines:

String path = Strings.stripJSessionId(request.getRequestURI());
String contextPath = request.getContextPath();

with:

String requestURI = (String)
request.getAttribute("javax.servlet.include.request_uri");
if (requestURI == null) {
requestURI = request.getRequestURI();
}
String path = Strings.stripJSessionId(requestURI);


I tried to debug the code and the filter is called, but then nothing is
displayed on the browser.. just a blank page..
If I call page directly(not the jsp) , it renders correctly..



Has anyone got a simple working example of this situation?

I would really appreciate id because I am going crazy..

Thank you very much.

Riccardo

Re: including wicket component into jsp

[bht]

Have you checked that the wicket filter is called?

I found that the struts filter does not call filterChain.doFilter().
That may or may not be your problem depending whether anything else is
in its path after it. I suspect however that this is what you need
otherwise how can Wicket get the request if the wicket filter is not
called?

Bernard

passing a map into PageParameters

[Fernando Wermus]

Hi all,
I need to pass a map into PageParameters. But I failed.

Map swfParameters=new HashMap();
...
swfParameters.put("token", "abc");
p.put(PanelIframe.SWF_PARAMETERS, swfParameters);

...
RequestCycle.get().urlFor(clazz, p);

The map is converted to "{token=abc}" like.

But when the Page for this request is called, there is an empty map into
PageParameters,

Is there a way to pass a map into PageParameters?

Why is getCallbackScript(boolean onlyTargetActivePage) is not called in the

called, but not the getCallbackScript method..

Could anybody please help me?

PageParameters parameters = new PageParameters(swfParameters);

This is how the hashmap is constructed in PageParameters..

Re: passing a map into PageParameters

[Fernando Wermus]

This is not what I want to achieve.

I need to pass a map of  parameters as just an entry into PageParameters and
other entries too.

For instance,


Map swfParameters=new HashMap();
swfParameteres.put("a", "1");
swfParameteres.put("b", "2");

PageParameters p=new PageParameters();
p.put("swfParameters", swfParameters);
p.put("other", "other");

Re: including wicket component into jsp

[rikizz]

Hi,

thanks for the reply. Yes i checked, and the wicket filter is called but
debugging wicket code i found that is not calling the onrender method. I
will investigate to find out way..
If anyone has a working example it would be great..

Generating static HTML pages with Wicket

[jverstry]

Hi,

I am new to Wicket. I would like to use Wicket to generate static html pages
from a Java application. I have created a MyPage.html and corresponding
MyPage.java files. MyPage extends WebPage.

I would to know if it is possible to generate the 'final' html page that
would be sent and displayed in a browser and save it in a local html file
instead. Is there a special method I could call on WebPage? Can you give an
example?

Many thanks, 

JVerstry

Thanks Stefan.

Actually i have an idea that jWicket is what i want. I have read that it
allows me to do the UI the jquery way but send events via ajax to the
server. The only thing stopping me here is lack of documentation.

Let me check out the demo .

Thanks again.

Links in DataTable

[Nelson Segura]

I am trying to create a table based on DataTable, in which one of the
columns has links on it.
I tried to use the strategy described here (LinkPanel):

https://cwiki.apache.org/WICKET/adding-links-in-a-defaultdatatable.html

But this has a problem: clicking in the links in succession soon causes
"component not found exceptions", or opening the link in a new window or tab
renders the current page unusable, with the same exception.

rg.apache.wicket.WicketRuntimeException: component . not found on page ...
 at 
org.apache.wicket.request.AbstractRequestCycleProcessor.resolveListenerInterfaceTarget(AbstractRequestCycleProcessor.java:426)
 at 
org.apache.wicket.request.AbstractRequestCycleProcessor.resolveRenderedPage(AbstractRequestCycleProcessor.java:471)
 at 
org.apache.wicket.protocol.http.WebRequestCycleProcessor.resolve(WebRequestCycleProcessor.java:144)
 at org.apache.wicket.RequestCycle.step(RequestCycle.java:1310)
...

I believe this is due to the fact that a new LinkPanel is created when
rendering each column cell, and that when the click happens, the current
LinkPanels are replaced by new ones, and so the original page is not usable
anymore, because it is referring to the original LinkPanels.

Our users make heavy use of opening links in a list in new pages or tabs, so
this is a big deal for us :(

Is there any solution for this problem? The only one I can think of is to
use AjaxLink instead, but I am not sure whether that is correct, or if it
could cause even more problems.

Any help?

-Nelson

Hi,

I figured out the issue for panel being rendered twice :)

The addresspanel.html was not started  with  tag... It directly has a
 tag..

It worked fine, when I constructed the tags with proper

Re: Links in DataTable

[Nelson Segura]

Jeremy, the code is below.

I did notice something while researching/testing more.
The LinkPanel solution DOES work for a DataTable. The problem starts when
changed to a AjaxFallbackDefaultDataTable.
I did testing based in the datatable example in the wicket examples.
Maybe using an AjaxLink instead of a normal link in the table is the right
answer.


Code is mostly taken from the page linked in the original email

public abstract class LinkPanel extends Panel {

private static final long serialVersionUID = 2062173455224348354L;

public LinkPanel(final Item item, final String componentId,
final IModel model, final String property) {
super(componentId, model);

AjaxLink link = new AjaxLink("linkCell") {

private static final long serialVersionUID =
2574434147588617330L;

@Override
public void onClick(AjaxRequestTarget target) {
LinkPanel.this.onClick();
}


};
add(link);
link.add(new Label("label", new PropertyModel(model,property)));
}

protected abstract void onClick();
}

- Usage ---

public class LinkPanelPage extends WebPage {

public LinkPanelPage() {
Form form = new Form("form");
final LinkPanelListProvider provider = new LinkPanelListProvider();
List columnList = new ArrayList(3);
//columnList.add(new PropertyColumn(new
Model("eMailAddress"),"eMailAddress"));
columnList.add(new AbstractColumn(new Model("eMailAddress"),
"eMailAddress") {
private static final long serialVersionUID =
-1822504503325964706L;

@Override
@SuppressWarnings("unchecked")
public void populateItem(Item cellItem, String componentId,
final IModel rowModel) {
cellItem.add(new LinkPanel(cellItem, componentId, rowModel,
getSortProperty()) {

private static final long serialVersionUID =
-4615958634366803506L;

@Override
protected void onClick() {
System.out.println("clicked on link");
}
});
}

});

columnList.add(new PropertyColumn(new
Model("firstName"),"firstName"));
columnList.add(new PropertyColumn(new
Model("lastName"),"lastName"));
AjaxFallbackDefaultDataTable table = new
AjaxFallbackDefaultDataTable("link-panel-table", columnList, provider, 3);
form.add(table);
add(form);
}
}

So does Wiquery:

label = new Label("item-name", model)
draggableBehavior = new DraggableBehavior
draggableBehavior.setOpacity(0.75f)
draggableBehavior.setRevert(new DraggableRevert(true))
label.add(draggableBehavior)

Re: Links in DataTable

[Nelson Segura]

Since AjaxLink is AJAX and not a proper link, then it does behave as a
normal link, i.e. middle click (open link in new tab or new window) does not
trigger the AJAX click even, which means you cannot chose to open the link
in a new page.

back to square one, except that know I know is a problem with
AjaxFallbackDefaultDataTable, not with DataTable.

extending AbstractFormValidator as a validation adapter

[Ray Weidner]

Hi all,

The application that I'm current writing already has its own validation
logic, but I would like to integrate its results into the existing Wicket
form validation so as to unify the feedback.  To this end, I'm trying to
extend AbstractFormValidator to wrap my system's logic.

The way my system's validation works is pretty simple and self-explanatory:

*public interface Validator {*
* **public ValidationResult validate (Record record, Action action);*
*}*
*
*
*public interface ValidationResult {*
* **public boolean isValid ();*
*
*
* **public Set  getGeneralErrorMessages ();*
* *
* **public Set  getFieldErrorFieldNames ();*
* *
* **public Set  getFieldErrorMessages (String fieldName);*
*}*

The ValidationResultImpl is pretty much a simple bean for setting and
getting error messages, both general, and by field.  Validator
implementations are specific to the need, and the specifics aren't important
here.

For my adapter, I'm able to get to a certain point, and I'm not sure what
call to make next:

*public class RecordFormValidator extends AbstractFormValidator {*
* **private Validator validator = null;*
* **private Action action = null;*
* *
* **public RecordFormValidator (Validator validator, Action action) {*
* **this.validator = validator;*
* **this.action = action;*
* **}*
*
*
* *...@override*
* **public FormComponent  [] getDependentFormComponents () {*
* **return new FormComponent [0];*
* **}*
*
*
* *...@override*
* **public void validate (Form  arg0) {*
* **Record record = ((Form ) arg0).getModel ().getObject ();*
* **Validation result = validator.validate (record, action);*
* *
* **for (String generalErrorMessage : result.getGeneralErrorMessages ()) {*
* **// TODO: ???*
* **}*
* **for (String fieldName : result.getFieldErrorFieldNames ()) {*
* **for (String fieldErrorMessage : result.getFieldErrorMessages (fieldName))
{*
* **// TODO: ???*
* **}*
* **}*
* **}*
*}*
*
*
In examples I see online, validation errors seem to be registered by calls
of the #error method.  It seems like I should be doing that here, too, but
what I don't know is:

   - Which object's #error method should be called?  The validator's?  The
   FormComponent corresponding to the field in question?  I want field-specific
   errors appropriately associated with their fields, so I can use filters for
   field-specific feedback, etc.
   - I already have my actual error strings, so how do I skip around the
   resource logic to just set the error message?
   - What should I do with my "generalErrorMessages," which aren't tied to
   any specific field?

Any help would be appreciated, thanks!

Re: handling error in DataProvider

[Igor Vaynberg]

the exception will be thrown as many times as there are tables. but
this exception does not fill in the stack trace so it should be fast.
profile the code and see where the time is.

Re: passing a map into PageParameters

[Ray Weidner]

I haven't had any success storing anything other than Strings in
PageParameters objects.  It makes sense, since these are supposed to
represent bookmarkable (i.e. GET) parameters.  If you're hoping to throw
arbitrary Maps into a PageParameters, you're going to be disappointed.  But
if you have an idea what kind of data is going to be in the Map (especially
if you're using generics, unlike your example), then you can write a pair of
methods to translate between Map and String for this purpose.

I'm not sure what limitations on characters that you might run into due to
the fact that they have to be embedded in a URL, so you have to try it out.
 However, I wouldn't be surprised if Wicket escapes everything cleanly,
meaning that you don't have to worry about such things.

Of course, you don't have to embed your Map within a PageParameters if the
page that you want to go to doesn't need to be bookmarkable.  In that case,
just pass your Map to the destination page object through a constructor of
your design, and call #setResponsePage on the page object.

Re: fast user input speed

[Igor Vaynberg]

this is not your typical usecase for a web application :) web
applications are limited by the round trip to the server - which is
limited by how fast your server is and what the user's connection
speed is.

i would try to profile your application and see if you can make it
faster, but i dont think you can do anything about a super fast enter
key double hit, the browser will lose the second key event while
trying to process the first.

i think you may be better off using something like gwt and pushing as
much of your business logic into the client as you can.

Re: CryptedUrlWebRequestCodingStrategy with JMeter

[Igor Vaynberg]

it is very hard to test this with jmeter because urls generated will
be different every time since a new random key is generated for every
session. you will be better served by turning off the crypted url
coding strategy for your junit tests.

if you want formcomponent specific errors then you have to map the
errors from your business logic to the wicket components and call
error on them.

there is error(IValidationError) but there is also error(String), call
the latter.

i usually report these kinds of errors on the form itself and have a
special feedbackpanel that filters those.

org.apache.wicket.WicketRuntimeException: Unable to write the response

[tommaso]

Hello,

This is my first post. I am not a web developer, I usually develop other kinds 
of systems, but for a quick project I have to do, I looked at JSF and I really 
did not like it. Finally, I have come across wicket and it was love at first 
sight. 

Now, so far everything has been straightforward, but I am now facing the first 
puzzle...

I have a page that takes a while to render and, while it's rendering, if the 
user does anything, then I get:

org.apache.wicket.WicketRuntimeException: Unable to write the response
 at org.apache.wicket.Response.handleException(Response.java:286)

 etc ...

Now, this would be ok, I suppose. The user clicks something while wicket is 
sending stuff and that operation has to abort. However, this except really 
corrupts things, after this exception the web page behaves very strangely, some 
of wicket:ids do not update well anymore etc...
In the book Wicket in Action it says that a page is single threaded and all I 
am doing here is using one single page, one sesion, two request, quickly one 
after the other, before the first one completes.

I am using: INFO  - WebApplication - [QuickStartApplication] 
Started Wicket version 1.4.8 in development mode
And I have downlowded a hello world project (quickstart) adapted it to 1.4.8 
(generics pretty much) and not yet refactored things as I am concentrating on 
business logic for a quick prototype. The webserver is jetty.

Ok, sorry for the long post, and I hope someone of you will be able to give me 
a couple of hints/tips (tried to google it, but did not find much).


Thanks,

Tommy
