Re: Server cannot find /app url after migration to 1.3 filter
Hi , I think it seems resin's problem (2.1.7). After a lot of combinations , I still cannot make the wicket filter work. The error (URL not found) is reported by apache , not by resin . which means the filter request is not passed to resin. After I assign port ( http://foo.bar.com:8080/app ) , everything works fine now. But other servlets are not required to assign port , it means http://foo.bar.com/servlet/OtherServlets works very well. ( servlets are mapped to /servlet/* URL pattern ) Therefore , it maybe resin's problem I think. To avoid exposing port 8080 , maybe I have to set a reverse-proxy in apache's config. ...
Re: Server cannot find /app url after migration to 1.3 filter
Yes , I use Apache as a front end. If any configuration goes wrong , servlets' requests will not be processed by resin, either. But http://foo.bar.com/servlet/other.servlet just works fine. (No port assign) It means resin (2.1.7) seems doesn't intercept filter's requests. I've also reported this issue to resin's maillist. 2007/10/2, David Bernard [EMAIL PROTECTED]: If I understand right you use Apache as a front end ? If it work when you access to resin via a direct call ( http://foo.bar.com:8080/app) then I don't think it a problem with resin but with your apache front-end configuration. What do you map from apache to resin (1)/app, (2)/app* or (3)/app/* ? In my experience you need to map (1 and 3) or 2. You don't need to map 1 and 3 only if you have a rewrite rule /app = /app/. Yes , I tried but in vain.

Re: Server cannot find /app url after migration to 1.3 filter
2007/10/2, David Bernard [EMAIL PROTECTED]: It depends of how you map/forward from apache to resin. What is your apache configuration? If it works when you access resin directly, what is done when you access throught port 8080, then it's not a resin problem.

Re: Server cannot find /app url after migration to 1.3 filter
Hi , I had a strong suspicion that WicketFilter (from 1.3 b3) not compatible with Resin ( I tried 2.1.17 and latest 3.0.24 ) I can install a very simple filter , just doing this : public void doFilter (...) System.out.println(before doFilter); chain.doFilter(req, res); System.out.println(after doFilter); And mount this test filter to /* , it works. That means it can intercept http://foo.bar.com/servlet/foo.bar.test.TestServlet; , and print the messages. But WicketFilter just cannot work correctly with Resin_with_apache. I have to manually assign to port 8080 to make the filter work. Anybody successfully install WicketFilter with Resin_with_Apache (mod_caucho.so) ?

WebPage for serving binary image data
Hi
I hope I can use wicket to serve image data.
I know I can extend org.apache.wicket.markup.html.image.Image and provide a
DynamicImageResource
but the generated image link is
http://localhost/app/?wicket:interface=:0:customImage::IResourceListener::
The image data is stored in the session and not bookmarkable, which is not
what I want.
I then created an ImagePage extends WebPage and override onBeforeRender() ,
and coding below :
HttpServletResponse response = ((WebResponse)
getWebRequestCycle().getResponse()).getHttpServletResponse();
try
{
response.setContentType(image/png);
OutputStream responseOutputStream = response.getOutputStream();
responseOutputStream.write(myImageBytes);
responseOutputStream.flush();
responseOutputStream.close();
}
catch (IOException e)
{
e.printStackTrace();
}
It works !!! And I can bookmark the image.
But there are warning output :
2008-12-26 02:20:42,919 ERROR wicket.RequestCycle -
org.apache.wicket.Component has not been properly rendered. Something in the
hierarchy of foo.bar.ImagePage has not called super.onBeforeRender() in the

at org.apache.wicket.Component.beforeRender(Component.java:1034)

Is this the standard way of outputing binary data ?
If not , what is the better way (wicket 1.3.5) ?
thanks.
Re: WebPage for serving binary image data
Well , What I need is parsing URL and generating a corresponding image from BufferedImage , not a bookmarkable link to internal file resource... for example : http://localhost/app/myImage/text/Hello/width/500 This will generate a 500x500 png , containing a Hello String.

This doesn't preload the images, but it is a simple way to do a Mouseover.
You could easily add a header contributor within the constructor of this
class that outputs some javascript to preload the images.
public class MouseoverImage extends Image {
private static final long serialVersionUID = 1L;
private final ResourceReference mImage;
private final ResourceReference mMouseoverImage;
public MouseoverImage(String id, ResourceReference image,
ResourceReference
mouseoverImage) {
super(id, image);
mImage = image;
mMouseoverImage = mouseoverImage;
add(new AttributeModifier(onmouseover, null, true, new
LoadableDetachableModelString() {
private static final long serialVersionUID = 1L;
@Override
protected String load() {
return this.src=' + urlFor(mMouseoverImage) + ';;

Re: [jira] Resolved: (WICKET-1712) Inheritance inside a Container throws WicketRuntimeException
But if I implement this Window-like panel by extending Border I have no way to notify the collapse/expand events to the containing content . In my previous implementation , the AbstractPullDownPanel defines two methods invisible()/visible() for successor to override , if they want to handle the collapse / expand events. But if I implement it in Border , and place the expand / collapse link to the top of the Border . Because the border is added to the panel , I find no way to notify the expand/collapse events to its containing panel.

Re: [jira] Resolved: (WICKET-1712) Inheritance inside a Container throws WicketRuntimeException
Thank you for such a practical IVisitor tutorial.
But I have another problem :
When traversalling the nodes , it cannot find any Component that implements
ExpandCollapseListener.
But the Panel that wrapped by the Border indeed implements
ExpandCollapseListener
Can you check where goes wrong ?
Here is the code :
public class PulldownBorder extends Border
{
private final WebMarkupContainer content;
private boolean expanded;
public PulldownBorder(String id , String title , boolean defaultShown)
{
super(id);
Label titleLabel = new Label(title , title );
expanded = defaultShown;
content = new WebMarkupContainer(content);
content.setOutputMarkupPlaceholderTag(true);
content.setVisible(defaultShown);
add(content);
content.add(getBodyContainer());
final Label collapseExpandText = new Label(collapseExpandText);
collapseExpandText.setOutputMarkupPlaceholderTag(true);
if (content.isVisible())
collapseExpandText.setModel(new StringResourceModel(collapse , this
, null));
else
collapseExpandText.setModel(new StringResourceModel(expand , this ,
null));
Link collapseExpandLink = new AjaxFallbackLink(collapseExpandLink)
{
@Override
public void onClick(AjaxRequestTarget target)
{
expanded=!expanded;
target.addComponent(content.setVisible(expanded));
PulldownBorder.this.visitChildren(new IVisitor()
{
@Override
public Object component(Component c)
{
if (c instanceof ExpandCollapseListener)
{
System.out.println(c + is ExpandCollapseListener );
((ExpandCollapseListener)c).setExpanded(expanded);
return CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;
}
else
{
System.out.println(c + is NOT ExpandCollapseListener );
return CONTINUE_TRAVERSAL;
}
}
});
if (!expanded)
target.addComponent(collapseExpandText.setModel(new
StringResourceModel(expand , this , null)));
else
target.addComponent(collapseExpandText.setModel(new
StringResourceModel(collapse , this , null)));
}
};
add(collapseExpandLink);
collapseExpandLink.add(collapseExpandText);
collapseExpandLink.add(titleLabel);
}
}
Here is the Panel that wrapped by PulldownBorder :
public class MyPanel extends Panel implements ExpandCollapseListener
{
public MyPanel(String id)
{
super(id);
PulldownBorder border = new PulldownBorder(border , Test Title ,
true);
border.setTransparentResolver(true);
add(border);
// blah
}
@Override
public void setExpanded(boolean value)
{
// blah...
}
}
Here is the output (click collapse, and folding the content) :
[MarkupContainer [Component id = content]] is NOT ExpandCollapseListener
[MarkupContainer [Component id = _body]] is NOT ExpandCollapseListener
[MarkupContainer [Component id = collapseExpandLink]] is NOT
ExpandCollapseListener
[Component id = collapseExpandText] is NOT ExpandCollapseListener
[Component id = title] is NOT ExpandCollapseListener
Why it cannot find any component implementing ExpandCollapseListener ? Where
goes wrong ?
Thanks a lot

Border fails to render if its contents are not visible by default (WICKET-1789 ?)
I don't know if the problem has any relation to WICKET-1789 https://issues.apache.org/jira/browse/WICKET-1789 But I have a very similar situation : My problem traces back to WICKET-1712 https://issues.apache.org/jira/browse/WICKET-1712 I want to create a component which can Expand and Collapse its content , just like a window. I originally inheritd Panel to implement it , but Igor Vaynberg told me that is wrong , the correct way is to use a Border. But several days passed by , I still cannot finish the component , I am stuck to the situation very much like WICKET-1789 : That the border fails to render if its contents are not visible by default. According to WICKET-1789 , it says 1.3.5 has fixed the problem , but I still have this problem. The attachment is my quickstart code , which draws two panels in one page , one panel is default expand , another is default collapsed. The default_expanded panel can successfully collapse and expand again and again. But the default_collapsed panel just has no response I tried every way I can think , but still find no solution. Can somebody help me check the code , telling me where goes wrong .

igor: Thank you very much , it works ! BR -- smallufo 2009/2/5 Igor Vaynberg igor.vaynb...@gmail.com remove border.settransparentresolver(true); instead of add(listViewContainer.add(listView)); do border.add(listViewContainer.add(listView)); now your component hierarchy is proper, things are actually inside the border - which is how the border is meant to be used. your main problem was this line: listViewContainer.setVisible(defaultExpanded) ^ you never reset this to visible when the border is expanded, simply removing this line will work since you are now using the border there is a problem with component use check when it comes to doing this sort of visibility https://issues.apache.org/jira/browse/WICKET-2079 so simply disable it in your application.init() getDebugSettings().setComponentUseCheck(false); and now you have a working collapsible border. -igor

[1.3.5] Wicket POST leaks backend server with apache's mod_rewrite
I have a front apache server (httpd-2.0.52-41.ent.centos4) , with a backend db/servlet server (internal IP). I want to use apache's mod_rewrite to redirect the jsp/servlet/wicket requests to the backend server. So I add these lines in httpd.conf : IfModule mod_rewrite.c RewriteEngine On RewriteLogLevel 0 RewriteRule ^/app(.*) http://192.168.1.2:8080/app$1 [P] RewriteRule ^/jsp(.*) http://192.168.1.2:8080/webtools$1 [P] RewriteRule ^/servlet(.*) http://192.168.1.2:8080/servlet$1 [P] /IfModule /app rewrite wicket requests , /jsp rewrites JSP requests , and /servlet rewrites servlet requests The backend server is 192.168.1.2 , which runs Resin 3.2.1 , listens port 8080. With this setting , JSPs and servlets both works correctly. All GET/POST requests work like a charm , users don't know their JSP/servlet requests are redirected internally. BUT , things not work with wicket's requests (from url '/app' ) In wicket , GET request works OK , the URL is correct . but every POST request are redirected to http://192.168.1.2:8080/app/xx , which is not connectable from internet.

wicket 1.4 : Link with no model
Hi
I am migrating my wicket 1.3 project to 1.4.
One problem is this :
Link personPageLink = new Link(personPageLink)
{
@Override
public void onClick()
{
setResponsePage(PersonPage.class);
}
};
add(personPageLink);
Because Link is generized , eclipse reports :
- Link is a raw type. References to generic type LinkT should be
parameterized
but , this link doesn't bind any model , it is just a redirection.
How do I parameterized this link ?
[1.4] override getObject() return type not the same with original model ?
Hi all
I've already converted most of my code from 1.3 to 1.4 , except this
situation :
Label intToStringLabel = new Label(intToString , new
PropertyModel(this , integer)
{
@Override
public Object getObject()
{
int value = ((Integer) super.getObject()).intValue();
switch(value)
{
case 1: return one;
case 2: return two;
case 3: return three;
}
return ;
}
});
add(intToStringLabel);
In the code , I want to output Integer of 1,2,3 to one , two and
three
In the code , PropertyModel is not parameterized , so I change to :
new PropertyModelInteger(this , integer)
and eclipse warns getObject() 's return type should be Integer
But what I want to return is String , not Integer . This doesn't work.
OK , then , I change my code to
new PropertyModelString(this , integer)
and eclipse warns
((Integer) super.getObject()).intValue();
Cannot cast from String to Integer.
I don't know what else can I do , How to parameterize this situation ?
Re: [1.4] override getObject() return type not the same with original model ?
2009/11/18 Jeremy Thomerson jer...@wickettraining.com Well, you can't make a subclass a different parameterized type than it's parent. It won't work. You should be using an Integer model for this and using a converter rather than a nested model to make it a string. That's what converters are for. Hi , Do you mean AbstractConverter ? Is there any code snippet that demonstrates how to implement a Converter and hook it into a page ? Thanks a lot.

http://cwiki.apache.org/WICKET/using-custom-converters.html
Thanks a lot , this solves my problem...
But , there is a more complicated situation :
Old code : (works in 1.3)
ListView poem = new ListView(poem , new PropertyModel(model , poem)
{
@Override
public Object getObject()
{
ListString result = new ArrayListString();
String poemString = (String) super.getObject();
StringTokenizer st = new StringTokenizer(poemString);
while(st.hasMoreTokens())
result.add(st.nextToken());
return result;
}
})
{
@Override
protected void populateItem(ListItem listItem)
{
listItem.add(new Label(poemLine ,
listItem.getDefaultModelObjectAsString()));
}
};
add(poem);
In the above code , it get poem ( a String ) from a PropertyModel , and
convert it to ListString ,
and then render each String in the populateItem() method.
I look into IConverter and AbstractConverter , both need to convert Object
to String , not what I need ( ListString )
How should I solve this problem ?
[1.4.3] RequestUtils.toAbsolutePath() skips the last value

Re: How to tackle Ajax Flooding
Wow , thanks for this great tip ...
But I have problem applying to Gmap2 :
I hope when user clicks the map , the map won't be able to receive any

Is there anything I missed ?

doesnt look like a lot of javascript to me. further you can factor it

Inject object to Wicket session by Servlet Filter , but : you can only locate or create sessions in the context of a request cycle
Hi all :
I'm trying to inject something to the Wicket Session by a Generic Servlet
Filter :
public class UserFilter implements Filter
{
private UserDao UserDao;
@Override
public void init(FilterConfig config) throws ServletException
{
WebApplicationContext wac =
WebApplicationContextUtils.getWebApplicationContext(config.getServletContext());
UserDao = (UserDao) wac.getBean(userDao);
}
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain
chain) throws IOException, ServletException
{
System.out.println(getClass().getName() + : UserDao = + UserDao);
// ... blah...
// do something , get user from cookie , authenticate cookie , and set
it to Session
// ... blah...
MySession s = MySession.get(); // error occurs !
chain.doFilter(req, res);
}
It seems I cannot get Wicket's session outside wicket's request cycle.
I searched and found WicketSessionFilter , but it seems it is for
Retrieving objects from wicket's session , not for Filter to inject
something to wicket's session...
How to solve this problem ?
How to create Wicket's session and inject to Wicket's life cycle using Servlet Filter ?
2010/1/9 smallufo small...@gmail.com

I searched and found WicketSessionFilter , but it seems it is for
Retrieving objects from wicket's session , not for Filter to inject
something to wicket's session...
I've almost solve this problem by looking into
org.apache.wicket.protocol.http.servlet.WicketSessionFilter , and
implements my Filter :
public class UserFilter implements Filter
{
private String sessionKey;
private UserDao userDao;
@Override
public void init(FilterConfig config) throws ServletException
{
WebApplicationContext wac =
WebApplicationContextUtils.getWebApplicationContext(config.getServletContext());
userDao = (UserDao) wac.getBean(userDao);
}
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain
chain) throws IOException, ServletException
{
HttpServletRequest httpServletRequest = ((HttpServletRequest)req);
// create a httpSession if there is no session
HttpSession httpSession = httpServletRequest.getSession(true);
WebApplication application = (WebApplication)Application.get(MyApp);
if (application != null)
{
sessionKey = application.getSessionAttributePrefix(null, MyApp) +
Session.SESSION_ATTRIBUTE_NAME;
//MySession extends WebSession
MySession mySession = (MySession)httpSession.getAttribute(sessionKey);
if (mySession != null)
mySession.setUser(getUserFromCookies(httpServletRequest));
else
{
//No mySession , need to create a MySession and inject to
httpSession
MySession newSession = new MySession(application , ); //
- How to get Request ?
newSession.setUser(getUserFromCookies(httpServletRequest));
httpSession.setAttribute(sessionKey, newSession);
}
}
chain.doFilter(req, res);
}
}
The problem is : when there is no Wicket's session , how do I create a
Wicket's session outside wicket's request cycle ?
WebSession needs a org.apache.wicket.Request to construct , how do I get
this Request in the filter ?
Thanks a lot.

Any servlet filter- like WebRequest interceptor or filter ?

Re: Any servlet filter- like WebRequest interceptor or filter ?
For example : A Wicket application may have many WebPages or Wizards which are inter-connected ... The interceptor(or filter , whatever called) can monitor the user's cookie , when some situation matches , he will be redirected to a specified page, after filling some forms , he will be redirect back to the original target page or wizard step...

Yes , indeed , if the form is in the second row (default invisible) , it
works , But I cannot get the first row's data (such as radioGroup's model
object will become null ).
Moreover , Form with multiple row , with something visible and something
extensible (default invisible), it is not so rare.
If the form is not inside a ListView , it will work.
But it just fails if it is inside a ListView.

I stepped through the code and found that the convertedInput is null when

from wicket.I look forward to seeing what the wicket developers have to
say.

Re: Cannot get default invisible TextField's ModelObject ?
I think it is a bug , and already submitted to JIRA https://issues.apache.org/jira/browse/WICKET-2694 https://issues.apache.org/jira/browse/WICKET-2694 2010/1/21 Chuck Brinkman chasb1...@gmail.com I looked some more and found the following: When it works, with my modification, FormComponent.getInputAsArray tries to get parameters for the TextField named more:moreForm:textfield. I looked in the parameter map or the RequestFacade object and found these: wicket:interface, wicket:ignoreIfNotActive, random, more:moreForm:textfield, radioGroup and more:moreForm:submit. And it finds the TextField. The version that fails is looking for TextField named more:textfield. The RequestFacade object has: wicket:interface, wicket:ignoreIfNotActive, random, forma_hf_0, radioGroup and more:submit. Is there a problem with forma_hf_0?

[Bug 1.3.6] Inconsistent RequestUtils.toAbsolutePath()
This is my code :
String s1 =
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(CurrentPage.class ,
pps).toString());
System.out.println(s1 = + s1);
Link link = new AjaxFallbackLink(link)
{
@Override

{
final String s2 =
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(CurrentPage.class ,
pps).toString());
System.out.println(s2 = + s2);
}
};
This is the result :
s1 = http://foo.bar:8080/app/CurrentPage
s2 = CurrentPage/foo/bar/para/meters
String s1 is what I need , it has http://foo.bar:8080/app/; in the head of
the string.
But why s2 don't have host and context name (app) in the head ?
It is inconsistent

Re: RequestUtils.toAbsolutePath()'s bug ?
I don't know if this is related to WICKET-1599 : https://issues.apache.org/jira/browse/WICKET-1599 2008/5/7 smallufo small...@gmail.com Environment : Wicket 1.3.3 Suppose the following code in a bookmarkable page , say FirstPage : When user pushes an AJAX button , the page builds a bookmarkable link : MapString , Object parameterMap = new HashMapString , Object(); parameterMap.put(index , myObj.getIndex()); PageParameters pps = new PageParameters(parameterMap); String absUrl = RequestUtils.toAbsolutePath(getRequestCycle().urlFor(SecondPage.class , pps).toString()); If the user navigates properly (by clicking links to the FirstPage) , the absUrl is correct : foobar/SecondPage/index/1/ after pre-adding http://; + req.getServerName() + contextPath + / , I can correctly build the (bookmarkable) link like this : http://www.foobar.com/app/foobar/SecondPage/index/1 BUT , if the user directly links to the FirstPage(copy / paste the FirstPage's url in the browser's url bar) , or clicks the SecondPage's link and back (by browser) , and pushes the AJAX button again... SOMETIMES , absUrl becomes : http://foobar/SecondPage/index/1/ , the preceding http://; is redundant !!! And , my bookmarkable link becomes : http://www.foobar.com/app/http://foobar/SecondPage/index/1 I can not successfully re-produce this error every time. but sometimes it just occurs . It seems it is a bug... PS : I know how to build a BookmarkablePageLink in the wicket way , But I have to do this for a special purpose.
Re: [Bug 1.3.6] Inconsistent RequestUtils.toAbsolutePath()
I don't know if this is related to WICKET-1599 :
https://issues.apache.org/jira/browse/WICKET-1599
2009/6/7 smallufo small...@gmail.com
This is my code :
String s1 =
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(CurrentPage.class ,
pps).toString());
System.out.println(s1 = + s1);
Link link = new AjaxFallbackLink(link)
{
@Override
public void onClick(AjaxRequestTarget target)
{
final String s2 =
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(CurrentPage.class ,
pps).toString());
System.out.println(s2 = + s2);
}
};
This is the result :
s1 = http://foo.bar:8080/app/CurrentPage
s2 = CurrentPage/foo/bar/para/meters
String s1 is what I need , it has http://foo.bar:8080/app/; in the head
of the string.
But why s2 don't have host and context name (app) in the head ?
It is inconsistent
Is it possible to make it consistent with s1 ?

2009/6/7 Johan Compagner jcompag...@gmail.com
can you debug and see what this returns for both situations?
((WebRequest)RequestCycle.*get*().getRequest()).getHttpServletRequest()
.getRequestURL().toString()
ok , here is my test :
String a1 =
((WebRequest)RequestCycle.get().getRequest()).getHttpServletRequest().getRequestURL().toString();
System.out.println(a1 = + a1);
String s1 =
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(CurrentPage.class ,
pps).toString());
System.out.println(s1 = + s1);
Link link = new AjaxFallbackLink(link)
{
@Override
public void onClick(AjaxRequestTarget target)
{
String a2 =
((WebRequest)RequestCycle.get().getRequest()).getHttpServletRequest().getRequestURL().toString();
System.out.println(a2 = + a2);
final String s2 =
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(CurrentPage.class ,
pps).toString());
System.out.println(s2 = + s2);
}
};
a1 = http://foo.bar:8080/app/CurrentPage
s1 = http://foo.bar:8080/app/CurrentPage
a2 = http://foo.bar:8080/app/
s2 = http://CurrentPage/
a1 , s1 are correct ,
a2 , s2 are totally wrong.
Re: [Bug 1.3.6] Inconsistent RequestUtils.toAbsolutePath()
I've attached a quickstart code , including error case , to WICKET-2312 https://issues.apache.org/jira/browse/WICKET-2312 I think the problem may come from bookmarkablePage parsing parameters... The CurrentPage is mounted to /CurrentPage by mountBookmarkablePage(/CurrentPage , CurrentPage.class); Test steps : Step 1: user browser to link to http://foo.bar:8080/quickstart/app/CurrentPage outer = http://foo.bar:8080/quickstart/app/CurrentPage inner = http://foo.bar:8080/quickstart/app/CurrentPage both are correct. But ... Step 2: Open browser to connect to : http://foo.bar:8080/quickstart/app/CurrentPage/key/value outer = http://foo.bar:8080/quickstart/app/CurrentPage/key/value/ inner = http://foo.bar:8080/CurrentPage/key/value/ outer is correct , but inner is wrong ! inner lacks of context(quickstart) and path(app) here.

[1.4.6] inconsistent setResponsePage behavior in AjaxButton , with 1.4.5
Suppose inside a BookmarkablePage which is mounted to CurrentPage , there is an AjaxButton , when clicked , it will setResponsePage(CurrentPage.class , pps) If a user is browsing http://foo.bar/app/CurrentPage/key/value , and submit the AjaxButton , In 1.4.5 , he will be redirect to http://foo.bar/app/CurrentPage/key/value , it is correct But in 1.4.6 , he will be redirect to http://foo.bar/app/CurrentPage/key/CurrentPage/key/value , it is WRONG I think it is related to wicket2312 patch.

Inject Dao ( with JPA impl) into Wicket without Spring ?
Hi
Is there any way to inject a DAO into Wicket without Spring ?
ex :
public interface PersonDao { some methods... }
public class PersonDaoImpl implements PersonDao , Serializable {
@PersistenceContext(unitName = data, type =
PersistenceContextType.TRANSACTION)
EntityManager entityManager;
.. other method implementations ...
}
public class CurrentPage extends WebPage {
@javax.inject.Inject PersonDao personDao;
}
It's not working , anybody know how to achieve this ?
server :
Resin 4.0.4
Re: Inject Dao ( with JPA impl) into Wicket without Spring ?
Is it possible to 'not' introduce any 3rd library / annotation to enable
this feature ?
Will a custom IComponentInstantiationListener be able to do this ?
2010/3/23 Igor Vaynberg igor.vaynb...@gmail.com
something has to do the injection, if not spring you can try
salve.googlecode.com or aspectj, etc

Re: Inject Dao ( with JPA impl) into Wicket without Spring ?
I am just curious :
I am trying Resin 4.0.4 , which natively supports JSR 330's
@javax.inject.Inject .
And I am able to inject the Dao to one Servlet without any problem :
public class HelloServlet extends HttpServlet {
@Inject
private PersonDao personDao; // it will automatically create PersonDaoImpl
(and inject PersistenceContext ) and inject to here.
...
}
Since WicketServlet is essentially a HttpServlet , there should be a way to
intercept the injection when in a JSR-330-enabled container (like Resin 4 ,
JBoss , Glassfish v3) ... But I don't know how ...
I think it will greatly reduce the webapp size (and memory footprint ,
probably) without spring.

I think yes, Wicket is already depending on cglib, so you could create
something like this:
http://fisheye6.atlassian.com/browse/wicket/branches/wicket-1.4.x/wicket-spring/src/main/java/org/apache/wicket/spring/SpringBeanLocator.java?r=HEAD
or for non-spring code check out the wicketstuff javaee-inject project.

Is it a good practice to use intern() in all ids ?
I am using a profiler to analyze an OOM heap-dump file , and find tons of duplicated Strings . These strings are mostly IDs of wicket components or PropertyModel's expression ... I wonder if it a good practice to intern() all these Strings ? such as : private final static String TIME_STR = time.intern(); add(new Label(TIME_STR , foobar));
How to get other page's localized messages ?
If I have two WebPages : Page1.java Page1.properties , which stores default value Page1_zh.properties , which stores Chinese translations And Page2.java How do I get Page1's specific localized message in Page2 ? I noticed the StringResourceModel , but it seems not what I want. StringResourceModel's constructor must pass a Component object , but I cannot new Page1 in Page2 Is there anything like : SomeModel(key , Page1.class) , so that I can get key bound to Page1 ? Thanks.

implicit key in PageParameter ?
Hi , I wonder how to build an implicit key when a Page is mountBookmarkablePage() ? Suppose I have a TagPage , that accepts a parameter : name , and if the TagPage is mounted to /tag prefix The url will look like : http://foobar.com/app/tag/name/abc I feel the name is redundant I hope I can achieve shorter url like this : http://foobar.com/app/tag/abc http://foobar.com/app/tag/other Is is possible ?

I have a page with such definition :
public class CrudPageT extends Serializable extends WebPage
{
public CrudPage(PageParameters pps , AbstractDaoT dao)
{...}
}
and here is how I initialize the page :
CrudPageUser page = new CrudPageUser(pps , userDao);
the userDao is a Spring injected DAO :
@SpringBean private UserDao userDao;
And in fact , UserDao extends Abstract Dao Pattern :
public interface UserDao extends AbstractDaoUser {...}
Here comes the problem :
I want to know which type is passed to CrudPage , I use the code :
ParameterizedType genericSuperclass = (ParameterizedType)
dao.getClass().getGenericSuperclass();
this.clazz = (ClassT) genericSuperclass.getActualTypeArguments()[0];
But it throws exception :
java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType
I then print the type :
System.out.println(dao.getClass() = + dao.getClass());
System.out.println(dao.getClass().getGenericSuperclass() = +
dao.getClass().getGenericSuperclass());
and found the dao is proxied :
dao.getClass() = class org.apache.wicket.proxy.$Proxy101
dao.getClass().getGenericSuperclass() = class java.lang.reflect.Proxy
Maybe that's why I cannot get the type ...
And ... how to solve the problem ?
Thanks a lot !
Re: How to I get an un-proxied Spring Bean ?
Hi , I tried : dao.getClass() = class org.apache.wicket.proxy.$Proxy101 dao.getClass().getGenericSuperclass() = class java.lang.reflect.Proxy dao.getClass().getSuperclass() = class java.lang.reflect.Proxy But still unable to get the dao class 2010/12/14 Pedro Santos pedros...@gmail.com proxyClass.getSuperclass() gives you the dao type
How to programmatically get PlatformTransactionManager of a DAO ?
I am developing a generic CRUD app , that can edit any Spring/JPA entities
with a AbstractDao pattern's implementation , such as UserDaoImpl ,
ForumDaoImpl ...etc
In my wicket page : I have to use @SpringBean to identify which
PlatformTransactionManager to use , such as :
@SpringBean(name=transactionManagerUser)
private PlatformTransactionManager transactionManagerUser;
private TransactionTemplate txTemplate;
public CrudPage(final PageParameters pps , final AbstractDaoT dao)
{
super(pps);
txTemplate= new TransactionTemplate(transactionManagerUser);
}
The problem is , these DAOs are using different transaction managers , such
astransactionManagerUser , transactionManagerForum ...etc.
I cannot hard-code these txManager's name in my code. I have to
programmatically get the dao's txManager . How to achieve that ?
Thanks a lot !
Environments : Spring 3.0.5 , Hibernate-3.6 , JPA2

ResourceReference.getResource() returns NULL ?
I want to build a DynamicImageResource which can scale internal (packaged)
images (with name : {index}.gif ) .
In getImageData() , I try to load a truly existing image , but cannot
getResource() , it returns null !
Here is my code :
public class ScaledImageResource extends DynamicImageResource
{
private ThreadLocalInteger index = new ThreadLocalInteger();
private ThreadLocalInteger width = new ThreadLocalInteger();
private ThreadLocalInteger height = new ThreadLocalInteger();
@Override
public IResourceStream getResourceStream()
{
ValueMap map = getParameters();
index .set(map.getAsInteger(index , 1));
width .set(map.getAsInteger(width , 50));
height.set(map.getAsInteger(height, 50));
return super.getResourceStream();
}
@Override
protected byte[] getImageData()
{
ResourceReference imageResource = new ResourceReference(MyPage.class ,
icons/byIndex/+index.get()+.gif);
http://foobar.com/app/resources/foo.bar.MyPage/icons/byIndex/1.gif does
exist !
try
{
System.out.println(imageResource.getResource() = +
imageResource.getResource()); // returns NULL
InputStream is =
imageResource.getResource().getResourceStream().getInputStream();
BufferedImage bufferedImage = ImageIO.read(is);
BufferedImage scaledImage = BufferedImageTools.getImage(bufferedImage,
width.get() , height.get());
byte[] bytes = null;
//scale image , build bytes , skipped here.
return bytes;
}
catch (Exception e)
{
}
return null;
}
}
And in Application's init():
getSharedResources().add(IMG_KEY, new ScaledImageResource());
mountSharedResource(/scaledImage, new
ResourceReference(IMG_KEY).getSharedResourceKey());
Note , the image file does exist there ,
and http://foobar.com/app/resources/foo.bar.MyPage/icons/byIndex/1.gif does
browsable !
But why cannot I getResource() of the imageResource ?

[6.7] How to set header of DynamicImageResource ?
Hi :
I wonder how to set header of DynamicImageResource ?
In 1.4 , it just override setHeaders(WebResponse response)
{
response.setHeader(Cache-Control , no-cache);
}
But , how to do this in 6.7 ?
If I override setResponseHeaders(ResourceResponse data , Attributes
attributes) ,
It seems there are two ways to setHeader :
data.getHeaders().addHeader(Cache-Control, no-cache);
and
((WebResponse) attributes.getResponse()).addHeader(Cache-Control ,
no-cache);
Which is correct ?
And...
in 1.4 , there is an isCacheable() method , where is it in 6.7 ?
Thanks .
Re: [6.7] How to set header of DynamicImageResource ?
Hi I just take Cache-Control:no-cache for example. What if I want to add additional header information, which is correct ? data.getHeaders().addHeader(key, value); ? or ((WebResponse) attributes.getResponse()).addHeader(key , value); ? Thanks.

[wicket 6] How to get InputStream from ResourceReference ?
In wicket 1.4 I can get InputStream from a ResourceReference : ResourceReference resRef = new ResourceReference(Page.class , xxx.png); InputStream is = resRef.getResource().getResourceStream().getInputStream(); But it seems invalid in wicket 6 I need to build a DynamicImageResource , which returns byte[] in getImageData() ResourceReference resRef = new PackageResourceReference(Page.class , xxx.png); (in fact , the true resRef depends on the attributes parameter) but I am stuck here.

[wicket 6] Modal unable to see page's properties anymore ?
I have a LoginModal which binds a LoginPage . In LoginModal.setWindowClosedCallback() method , I use LoginPage.isSuccessful() to judge if the user login successful. If login successful , I refresh the page , or do nothing. LoginModal code : http://pastebin.com/nLU2akzV LoginPage code : http://pastebin.com/PqfLwsNg It works in wicket 1.4 , but failed in wicket 6 In LoginPage , I can see user correctly login , and the successful = true is set. But LoginModal can only see the old successful value (which is FALSE). No matter I read the property (isSuccessful() ) or through reflection PropertyModel : boolean successful = (new PropertyModelBoolean(loginPage, successful)). getObject().booleanValue(); It just returns FALSE. I notice it may be page serialization problem introduced in wicket 1.5 . My page has an integer attached , such as /app/?1 , no matter how I refresh the page , I just see the LoginPage's isSuccessful is FALSE. But if I manually browse /app/ (no trailing integer) , the user is logged in. (I set something in the httpSession in LoginPage) I searched the maillist , try to override *isVersioned() and return false*, but everything is the same How to solve the problem , making LoginModal able to see LoginPage's latest property ? Thanks !
Re: [wicket 6] Modal unable to see page's properties anymore ?
Hi , I found no IPageReference class . If you mean PageReference , I finally found the solution: http://pastebin.com/bes3H9w3 Though the solution seems not so intuitional compared to wicket 1.4 2013/5/7 Martin Grigorov mgrigo...@apache.org Hi, You should not keep references to other page instances. Instead pass IPageReference: page.getPageReference(). Later you can do: MyPage page = (MyPage) pageRef.getPage(); page.setXyz(); But in your case I think you should use the Session. If the login is successful then bind a session and set the flag. Then redirect to LoginPage and in its constructor check whether there is a session, and whether the flag is set and redirect to the post-login page.

[wicket 6] Create/Register Spring Bean in wicket ?
Hi , I wonder if it possible to programmatically create / register a spring bean in wicket? maybe in Application.init() ... Most documents about spring are making use of existent beans , and inject to WebPage or Panel via @SpringBean , and it indeed works well.

Re: [wicket 6] Create/Register Spring Bean in wicket ?
2013/5/11 Marco Springer ma...@glitchbox.nl
Maybe this is too simple but:
Did you define this bean in the applicationContext.xml?:
bean id=myobj class={impl. class}{possible properties}/bean
No this is not what I want.
The whole story is ...
I have two maven repositories :
One is *business-layer* , which defines whole business objects , service
layers , and make use of SpringConfig and package scan to build a lot of
beans .
Another is *wicket-layer* , which depends on business-layer , and makes use
of beans scanned in the business-layer and serve the web.
The problem is :
All the beans are defined ( package scanned ) in the business-layer.
There is no spring's xml or spring's @Repository class or SpringConfig
settings in the wicket-layer.
But I have some idea of implementing some interface which depends on
wicket's library.
Such as getting absolute url of a DynamicImageReference or a
PackageResourceReference
, which depends on RequestCycle and wicket's components.
I wonder how to programmatically generate such bean and inject to the
spring ?
class MyApplication extends WebApplication {
@SpringBean dao; // defined in business-layer , and injected
successfully.
public init () {
getComponentInstantiationListeners().add(new
SpringComponentInjector(this));
Injector.get().inject(this);
*URLGetter urlGetter = new URLGetterDynImgRefImpl(dao);*
// How to inject this urlGetter to spring ?
}
}
In the above code , how to inject the urlGetter object to Spring ? so
that other wicket WebPage or Panel can use @SpringBean(name=urlGetter) to
get the object ?
Thanks.
Re: [wicket 6] Create/Register Spring Bean in wicket ?

Deserialization InvalidClassException : no valid constructor
Today I encountered one famous deserialization problem :
InvalidClassException : no valid constructor
I googled and found some solution , but all are in-vain.
The solution says the first non-serializable super class should define a
no-arg constructor.
But I try to define a no-arg constructor to EACH class of the HIERARCHY ,
and EACH class implements Serializable... (which is not necessary , but I
want to make it simple , to pinpoint the problem)
My base class is an abstract class extends BufferedImage (java 2D)
while BufferedImage is not Serializable
So I make my abstract class implements Serializable and define a no-arg
default constructor.
The total hierarchy is :
public abstract class AbstractChart extends BufferedImage implements
Serializable {
public AbstractChart() {// I try to remove this constructor ,
but in vain
super(0 , 0, TYPE_INT_ARGB);
}
}
and first child class :
public class ChildChart extends AbstractChart implements Serializable {
public ChildChart() {
super(); // or not calling super()
}
}
and the grandson class :
public class GrandsonChart extends ChildChart implements Serializable {
public GrandsonChart() {
super(); // or not calling super()
}
}
No matter I calls super() in ChildChart or GrandsonChart ,
Caused by: java.io.InvalidClassException: foobar.GrandsonChart; no valid
constructor
It happens when I click a button ,use ajax to paint this GrandsonChart ,
and click another page , and use browser back .
The browser will be redirected to /context/wicket/page?xxx (The error page)
The screen shows :
Could not deserialize object using:
class
org.apache.wicket.serialize.java.JavaSerializer$ClassResolverObjectInputStream
and in the console log , I can see this InvalidClassException is thrown.
Any way to solve this problem ?
(I've already added default no-arg constructor , and make each class
implements Serializable , but still not working )

Re: Deserialization InvalidClassException : no valid constructor

But in my example , I cannot modify BufferedImage (to add a no-arg
constructor)
What should I do if I want to output a BufferedImage (and make back button
work) ?
2013/5/14 Jonas barney...@gmail.com
This could only work if BufferedImage itself had a no-arg constructor.
It is it the first non-serializable class in the hierarchy that needs to
have it,
not the first serializable one, like in your example.
Besides, you would still lose all data stored in the BufferedImage's fields
(i.e.
the image stored in it).

Re: Deserialization InvalidClassException : no valid constructor
I solve this problem by making the BufferedImage transient.
2013/5/27 Jonas barney...@gmail.com
Well, you can't serialize the BufferedImage, but maybe you can serialize
whatever data you've used to render BufferedImage's contents,
i.e. instead of saving the image, save whatever is necessary to recreate
the image?
Or, you could store the BufferedImage's content to an actual image file
(using ImageIO)?

I see the src, saying : @deprecated use [EMAIL PROTECTED] #Fragment(String, String, MarkupContainer)} But I don't know what should I fill in the MarkupContainer . ... ? span wicket:id=myPanelExample input (will be removed)/span wicket:fragment wicket:id=frag1panel 1/wicket:fragment wicket:fragment wicket:id=frag2panel 2/wicket:fragment add(new Fragment(myPanel1, frag1); Just like this easy example above (in the JavaDoc) , what is the recommended way in 1.3 ?
FormComponentPanel and setConvertedInput()
Hi , I am evaluating FormComponentPanel .
I looked into the document , it seems setConvertedInput() is the proper way
.
I use another method , which skips the setConvertedInput() , I don't know if
it is suggested :
Here is the code :
public class TimePanel extends FormComponentPanel
{
private Time time;
public TimePanel(String id , Time time )
{
super(id);
this.time = time;
add(new CheckBox(beforeChrist , new PropertyModel(time ,
beforeChrist)));
add(new TextField(year , new PropertyModel(time , year)));
add(new TextField(month , new PropertyModel(time , month)));
add(new TextField(day , new PropertyModel(time , day)));
add(new TextField(hour , new PropertyModel(time , hour)));
add(new TextField(minute , new PropertyModel(time , minute)));
add(new TextField(second , new PropertyModel(time , second)));
}
}
I embed this TimePanel to a form :
Time time = new Time(); //my custom Time class
add(new TimePanel(timePanel , time));
add(new Button(button)
{
@Override
public void onSubmit()
{
System.out.println(time = + time);
}
});
It works .
It seems by this way , I can skip implementing setConvertedInput() , right ?
Is there any drawback ?
Is this a suggested way ?
How to get a form component's value that is not a sub-node of the Form.
I have a Form component : SomeCheckGroup added to a SomePanel. For screen arrangement purpose , this SomePanel is not a sub-node of the Form , it's outside of the Form . It looks like this : OutmostPanel add FormPanel FormPanel add MainForm MainForm add other form components OutmostPanel add SomePanel SomePanel add SomeCheckGroup1 SomePanel add SomeCheckGroup2 SomePanel add SomeCheckGroup3 ... How do I get the value of SomeCheckGroup when MainForm submit() ? Now , I could only use AjaxCheckBox in SomeCheckGroup to update the MainForm's model , but sometimes , it seems maybe network delay problem , cause some synchronized problem , which set null to the form's model , it's hard to debug , and I feel it is bandwidth consumptive... But I cannot find a way to not using AJAX and notify the checkGroup latest model to MainForm's model . Can somebody give me a hint . Thanks in advanced.
Re: How to get a form component's value that is not a sub-node of the Form.
Can you specify details more precisely ? According to http://www.thescripts.com/forum/thread95602.html It seems nested forms is forbidden. 2008/1/25, Eelco Hillenius [EMAIL PROTECTED]: You could try nested forms.

Wicket as a front controller ?
Hi . I wonder if wicket can act as a servlet front controller ? I have a normal wicket webapp , but I need one endpoint to process Yahoo's bbAuth's request. Yes , I can write normal servlet to process this , but normal servlet lacks of spring injection and cannot access to wicket's environment. Therefore , I need a specialized wicket endpoint , and that endpoint must coexist with my wicket app . How to do that ?
Re: Wicket as a front controller ?
Thank you , but I want a (bookmarkable) page without HTML Is it possible ? 2008/2/24, Kent Tong [EMAIL PROTECTED]: smallufo wrote: I have a normal wicket webapp , but I need one endpoint to process Yahoo's bbAuth's request.

Something like http://foo.com/MyApp/app/?wicket:bookmarkablePage=:com.foo.MyApp.MyPage
Re: Wicket as a front controller ?
I just need to redirect. If bbAuth token is correct , then set correct Wicket Session and redirect to proper page. If incorrect , then redirect to another page. If I use pure servlet to implement this , I have to hard code the redirecting URL , and can only use HttpSession ... 2008/2/24, Kent Tong [EMAIL PROTECTED]: smallufo wrote: Thank you , but I want a (bookmarkable) page without HTML Is it possible ?
