Re: Handling 404 in wicket?

[Andrew Lombardi]

Marc,

this has been covered before, and its not too specific to wicket, you  
can add the needed items in your web.xml, here's an example:

Hi,

within a Project there is the need for a "customized" 404-Page.
Users with a misspelled url should get a standard 404-Page and
some "hints" which pages they possible wanted to show. The other
point is that I would like to reuse the templates, inheritance and  
so on

and not to create some "special" jsps for this.

I've some messages on this list in mind which are related to this
topic but I haven't found them anymore.
Ist there anything easy (like an "setErrorPage") to get all requests
which are directed to non existing Pages?


Thanks for your help

Marc

Re: making a HTTP request directly in Wicket

[Marcelo Morales]

It can connect and stall forever. People restart firewalls you know. I
must insist on using at least setReadTimeout(int).

Re: Using Eclipse & Wicket for Modular Webapps

[Fabrizio Giudici]

The conclusion says:

"But most important: it would be really interesting to actually build a 
real Wicket application
with Eclipse. Only real world experience can show whether itʻs worth the 
hassle in the end."


I think it's definitely possible. I'm running two customizations of a 
Wicket application based on the NetBeans Platform (I posted a few weeks 
ago a link about that: 
http://netbeans.dzone.com/articles/using-netbeans-platform-server) and 
so far everything works fine, in spite of the application being 
relatively complex. I was worried about some potential issues with the 
classloaders, which is a constant risk every time you deal with modular 
frameworks such as Eclipse Platform or NetBeans platform, but none 
manifested so far. BTW, I'm trying to understand why I didn't have to 
deal with the IClassResolver for bookmarkable pages...

path to resource ../ attached at the beginning

[Andreas Petersson]

hi!
in the .html file i have references to images such as


in the preview this is the correct path.
as soon as i startup the apllication wicket writes out the image as


1) why is ../ appended at the beginning?
2) how can i replace the path with something like

the css is included via the Start.java with  
add(new StyleSheetReference("mainCss", new CompressedResourceReference(Start.class,"../res/main.css")));

since the pictures are added in the classpath, they must be accessed via 
/resources/
it would be optimal if i can acieve this just by editing the html file, to keep 
the previewability.
i hate to have duplicate references to the same resource. (java +html that both 
contain links to the same images...)

best regards
andreas

problem deploying quickstart application on tomcat+apache (mod_jk)

[Vika]

Hi, 

I have no problem running quickstart in eclipse on jetty. However having
problem deploying it on tomcat/apache. Here are the steps I followed:

1. Modified build.xml - changed wicket-quickstart to quickstart
2. ran ant war and dropped quickstart.war file into ~tomcat/webapps
3. added to mod_jk the following
### 
Alias /quickstart "/usr/local/tomcat/webapps/quickstart"


Options Indexes FollowSymLinks
DirectoryIndex index.html index.htm index.jsp


JkMount /quickstart/app/* ajp13

ErrorLog logs/quickstart-error_log
TransferLog logs/quickstart-access_log

4. after restarting tomcat and apache i went to this url in web browser
http:///quickstart
and got redirected to
http:///quickstart/app 
and got a message
"The requested URL /quickstart/app was not found on this server."


I have several other project with servlets running on the same instance of
tomcat/apache. Any idea what i might be missing with wicket quickstart?

thank you in advance!

Vicky

Re: How to execute Wicket project in Eclipse

You will have to run your Wicket application with a J2EE application server.

I've found Run-Jetty-Run to be extremely easy-to-use:

Handling 404 in wicket?

[Marc Ende]

Hi,

within a Project there is the need for a "customized" 404-Page.
Users with a misspelled url should get a standard 404-Page and
some "hints" which pages they possible wanted to show. The other
point is that I would like to reuse the templates, inheritance and so on
and not to create some "special" jsps for this.

I've some messages on this list in mind which are related to this
topic but I haven't found them anymore.
Ist there anything easy (like an "setErrorPage") to get all requests
which are directed to non existing Pages?


Thanks for your help

Project.

Then it is asking for Project name. So gave some name..

Then it is creating MyApplication which extends WebApplication and
configured in the web.xml file.

then i created HelloWorld.java

package com.example;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;


public class HelloWorld extends WebPage {

HelloWorld()
{
add(new Label("msg","sfjhdsjfdhjdjkf"));
}

}

and modified MyApplication.java file

public class MyApplication extends WebApplication {
public MyApplication() {

}

public void init() {

}

@Override
public Class getHomePage() {
// TODO Auto-generated method stub
return HelloWorld.class;
}
}

and created HelloWorld.html



Insert title here


Message goes here



Now Iam unable deploy and run the application.

Re: IoC: how to best handle non-serializable fields in wicket

[francisco treacy]

another option is to use salve (http://code.google.com/p/salve/).
instead of calling guice's injector as a service locator you use
@Dependency, that will lookup and inject your dependency (behind the
scenes it adds the class a proxy through bytecode instrumentation).

public class myLDM extends LoadableDetachableModel {

 @Dependency myDAO;

 public Object load() {
  return myDAO.get(...);
}

Proper hook for conversational state that also works with tests

[cpopetz]

Hi,

I'm currently responsible for maintaining the Seam/Wicket integration for
the Seam team.  Seam maintains a "conversational" context, a session-based
map that is keyed by an id associated with a set of requests.  Previously
the wicket integration worked by wrapping every redirect or outgoing url and
adding the conversation id as a parameter, and then restoring the
conversation based on that parameter in a servlet filter.  While this works,
it's ugly, and doesn't play with with various URL coding strategies.  

So instead, I've been working on storing the conversational id in Page
metadata.  I did this by providing a new WebRequestCycleProcessor subclass
which in resolve() looks for IPageRequestTarget or
BookmarkablePageRequestTarget, pulls the page out, and restores the
conversation if the parameter is present in metdata.  Correspondingly, in
respond(), I do the inverse.  

This works great when running in-container, but isn't playing well with
tests that use ajax.  When an ajax link is clicked in-container, the full
request cycle is step()ed through.  But BaseWicketTester.clickLink(), which
I presume is the appropriate thing to use, does:

AjaxLink link = (AjaxLink)linkComponent;

setupRequestAndResponse(true);
WebRequestCycle requestCycle = createRequestCycle();
callOnBeginRequest(requestCycle);
AjaxRequestTarget target = new 
AjaxRequestTarget(link.getPage());
requestCycle.setRequestTarget(target);

link.onClick(target);

// process the request target
processRequestCycle(requestCycle);


This means that the link's onClick method is called before my request cycle
hooks have a chance to restore conversational state.  

Is there an alternate way I should be hooking into wicket so that I can
reliably intercept requests to pages and retrieve/store metadata?

Thank you,
-Clint

Using Eclipse & Wicket for Modular Webapps

[Thomas Mäder]

Hi Folks,

I've been experimenting with getting the Eclipse plugin engine up inside a
wicket application. The idea is to build Wicket applications out of plugins.
You can find an article about my experiences (+sample code) here:
http://devotek-it.ch/stuff.html
I'm grateful for any feedback, both concerning the Eclipse/OSGI and the
Wicket part.

enjoy the weekend

Thomas

Re: Another question for best practices

[uwe janner]

ok, i got it :-)

the downside is, that then you have the names of the css in the java  class;
as this is more the duty of the html designer, i looked for a way to let the
html designer say which css to take (and pull it from a static source) and a
mechanism that converts this to the "real" url by wicket.
so i used the  solution.

Re: Another question for best practices

[Thomas Mäder]

No, what I meant was a single tag link and a list view:



and in code:

List cssFiles= Array.asList(new String[] { "base.css", "special.css" });
add(new ListView("cssList", cssFiles) {
  public void populateItem(ListItem item) {
 String cssFile= item.getModelObjectAsString();
 item.add(new AttributeModifier("href",  new AbstractReadOnlyModel() {
public Object getModel() {
   return +"/"+cssFile
}
 });
  }
});

this is off the top of my head, just to see if we're even on the same page.

Re: The same *.css and *.js on multiple pages

[Trent Larson]

One solution is the "extend" functionality (eg. "wicket:child" and
"wicket:extend").  We use a "BasePage" that all our pages extend, and it
contains all our javascript.  It doesn't add anything else, so there is
almost no HTML (just the "html", "head", and "body" tags) and the Java file
for that page is just a blank class.  (Just make sure that, if they add
anything else to the header, all the extending pages use a "wicket:head" tag
for the additional content.)

Hi,

this isn't actually related to wicket, but anyway, I think what you're

Re: example application for spring wicket hibernate

[cmoulliard]

Another very interesting example is described here in the java world
publication :

http://www.javaworld.com/javaworld/jw-09-2008/jw-09-wicket3.html

This is (from my point of view) the best spring/hibernate implementation see
with Wicket (have a look to the code of the example : scramble-spring)

Compare to the phonebook that I know, spring service dependency is injected
in the web page through @SpringBean which is not the case in phone-book
example

For my static pages, I use markup inheritance (as I do with all the

I'm using a servlet error-page mapping to display my custom NotFound

/404


I have some anlayzing code on my NotFound page to check where the 404

This works when I use setResponsePage(NotFound.class) in other pages,

Any ideas on how to get at the original URI that triggered the 404?

If the interface extends Serializable and you implement it, you
implement Serializable.  That's not a good idea for service/dao

Browser auto form filling

[John Patterson]

Hi,

I use generated forms for a "Contact Us" page and have noticed that my email
address is not automatically filled in for me like on many sites.  I guess
this is due to the name of the form input being something like
"rows:0:row:input" which Safari has not come across before.  Is there any
way to change the input name attribute or control this behaviour another
way?

Thanks,

John

Re: Another question for best practices

[uwe janner]

hi thomas,

i dont really get your idea, maybe an example?

what i did was: write the followning in the html:


 and many more ...


and then i "repeat" myself in the page class (CssLink just puts the dynamic
url part before the original href value):

add( new CssLink("baseCss"));
... and many more ...
add( new CssLink("specialCss"));

would look shorter if i do it in a loop iterationg over { "baseCss",
. "specialCss" } but the bad thing about it is that i have to keep
these two in sync;
so i think i would implement it like this:

and in the page i would add my custom ChangeHrefInBodyComponent, which would
directly change the hrefs in the body markup (not the child link components)
- bc i dont want to add those components explicitly by hand:
add( new ChangeHrefInBodyComponent( "cssLinks" );

or even simpler:

  
    and many more ...
  


and nothing to add in the page (as with  )

cheersuwe!

Re: IoC: how to best handle non-serializable fields in wicket

[Sergey Didenko]

Hi Andreas,

Well, may be my question is silly, but:

What about making "dao" a local variable in your component handlers?
Then you can get rid of that serializing-deserializing of dao as a
Component member.

Does this approach have too much overhead? Does it make some things impossible?

Cheers, Sergey.

Btw, we're working with the same combination (spring/ibatis/wicket) and 
you'll love it :)

2) Install a SpringComponentInjector in your application, e.g.
class MyApplication extends WebApplication {
  public void init() {
   super.init();
   addComponentInstantiationListener(new
SpringComponentInjector(this));
   }
}
  

Yes, also did this:

public class JPSApplication extends SpringWebApplication implements
IUnauthorizedComponentInstantiationListener{

@SpringBean private LookupTableDAO ltDAO;

public void init(){
super.init();

addComponentInstantiationListener(new
SpringComponentInjector(this)); //for the SpringBean
InjectorHolder.getInjector().inject(this);



You do not need the last line here. Adding the SpringComponentInjector is
sufficient. AFAIK the InjectorHolder is needed within classes, which do not
extend a wicket component.

Cheers, Kai

No. First of all, your page class should not keep growing larger and larger.
You should put most of the logic into your domain classes, not in the page
class. Once you do that, your page should be clean and easy to understand
despite the presence of an anonymous Form subclass.

Second, the structure of the Java code should match the structure of the
HTML file. This will make it easier to understand how they work together.

Bug in wicket-stuff phonebook

[cmoulliard]

Hi,

I would like to mention that there is a bug in the maven pom.xml file of the
project phonebook because the properties files located here
"wicketstuff-core\phonebook\src\main\java\wicket\contrib\phonebook\web\page"
are not at copied in the WAR generated. In consequence, the following error
is generated :

WicketMessage: Can't instantiate page using constructor public
wicket.contrib.phonebook.web.page.ListContactsPage()

Root cause:

java.util.MissingResourceException: Unable to find property: 'actions' for
component: [class=wicket.contrib.phonebook.web.page.ListContactsPage]
at org.apache.wicket.Localizer.getString(Localizer.java:342)
at org.apache.wicket.Localizer.getString(Localizer.java:118)
at org.apache.wicket.Component.getString(Component.java:1869)
at org.apache.wicket.Component.getString(Component.java:1856)

Can the owner of this application adapt the pom.xml to copy these properties
files in the WAR ?

Regards,

Also had this in my web.xml:

 

org.springframework.web.context.ContextLoaderListener
 

My error was that all my DAOs and my sqlMapClient was defined in a file
called persistance.ibatis.xml.  I needed to include this file in my
applicationContext.xml :




Without this declaration it seems Spring couldn't find the DAOs.

Thank you once again for your assistance!!

Kind regards

Re: Custom Domain Exception Handling

[Sven Meier]

In our projects we let domain and service exceptions trickle down into 
Wicket and be handled in a custom RequestCycle.
Of course this requires them to be RuntimeExceptions, but this seems to 
be en vogue anyway.


Nice thing is this technique works non-form requests (e.g. links) too.

All,

I am working with a domain where the POJOs have a method that checks there
values, and throws an exception with the error message if there is a problem
with one of there property values.  I am using panels to model these
objects, is there something I can do to utilize this behavior when a form
submits.  So that the form submit, and persisting of the models properties
will make the panel aware that there is an error.

I"m not looking for a full explanation of an implementation, just a quick
explanation of how the model objects properties get persisted.

Thanks!
