using OpenJPA with wicket?
I'm just getting my feet wet with Wicket and OpenJPA. I've got the basics of both and have started prototyping parts of an upcoming project in each and everything was going great. Then I tried to put the two technologies together and hit a wall. I'd written the OpenJPA pieces in a standalone application. Moving to a web container (Tomcat), I saw a recommendation to annotate the servlet code with something like: @PersistenceUnit private EntityManagerFactory emf; Of course, with Wicket, we don't write a servlet...and now I'm drawing a blank as to where I should go next?.

there is absolutely nothing wrong with having authenticate() on

session is an object in wicket, why should it fall prey to the anemic
data model antipattern? why should it contain data only and no
behavior?
what looks better?
session.setuserid(long id);
session.getuserid();
or
session.authenticate(credentials cred);
session.getuserid();
the former has absolutely no encapsulation or protection of data,
anyone can set whatever id they want via a simple call to setuserid().
the latter properly encapsulates the user id and protects against code
abuse.
there are a number of technologies that allow you to break out of the
anemic data model mold by allowing, in this case the session, objects
to hold on to references to services and yet remain lightweight.
wicket provides the lightweight serializable proxies which can be used
inside any object.
class mysession extends websession {
@SpringBean/@Inject
private SessionFactory sf;
private long id; <== id is private with no direct setter
public mysession(webrequest req) {
super(req);
injectionholder.getinjector().inject(this); <== injects sf var
}
public void authenticate(credentials creds) throws AuthException {
user u=sf.getnamedquery("auth")..
id=u.getid();
}
salve.googlecode.com removes the reference field altogether and
rewrites field access with a lookup.
class mysession extends websession {
@Dependency
private SessionFactory sf; <== field will be removed via bytecode
instrumentation leaving the session object lightweight and
serializable
private long id; <== id is private with no direct setter
public mysession(webrequest req) {
super(req);
}
public void authenticate(credentials creds) throws AuthException {
user u=sf.getnamedquery("auth") <== this access to the removed sf
field will be rewritten as a lookup from configured ioc container
...
id=u.getid();
}

wicket URL rewrite in Opera
Hi,
My wicket site works in IE6, IE7, Safari, Firefox 2,3 but not in Opera. When
first visiting the site everything works fine but when requesting an item
opera gives me an error message.
The message is in swedish but this is a free translation ( "URL is
redirected to .Click on the link to visit the page." )
Here are some links to the webpage.
www.eddyemery.com
www.eddyemery.com/items/brand/17
the first time I visit the link it works but if I refresh the page it does
not. I use NonVersionedHybridUrlCodingStrategy that I have copied from a
user from this forum ( can not remeber from who )
public final class NonVersionedHybridUrlCodingStrategy extends
HybridUrlCodingStrategy {
public NonVersionedHybridUrlCodingStrategy(String mountPath, Class pageClass) {
super(mountPath, pageClass);
}
@Override
protected String addPageInfo(String url, PageInfo pageInfo) {
// Do not add the version number as super.addPageInfo would do.
return url.replace( ".", "" );
}
}
Re: How to remove a row from DataTable?
Thanks, your suggestion works like a charm.
I like the technique of using abstract method, you have a Swing development

Thanks again.

Re: Weird DatePicker / DateTextField off by one hour
Hi Ryan,
this should be a timezone issue. The date is timezone sensitive, so take
a look at java.util.TimeZone and especially at what timezone your
datepicker / datefield is set to use. You might have to override that.
Have a look to the Timezone of the Date object in your debugger before
persisting to DB, and afterwards.
I bet there's a TZ conversion happening somwhere that subtracts that one
hour you are missing. Also check for Daylight Savings time, that might
explain why it only happens with certain dates.
BR,
Stephan

Re: Tools for Managing a Wicket Project
No tools require an internet connection all the time. The repositories Nexus, Archiva etc are local to your site. They only download from the internet when you ask for something the first time. That is one reason for having a local repository manager. Then you have your personal repository as always with Maven. If you are offline, but have a class library on some media, e.g. a USB stick, you can deploy that to your local repository. Hope this helps. /Per On Thu, Apr 30, 2009 at 12:47 PM, Geeta Madhavi wrote: > Hi... > > U can use Maven,Eclipse latest version for development..Server as Tomcat or > any other you wish..but use Maven instead of ant.

Re: How to remove a row from DataTable?
I don't know if you can remove one row and just update the row as you can
with TreeTable but maybe some here could guide you.
If it is good enough to update the whole table then maybe somthing like
this. this is typed from my head so there may be errors.
public abstract DeleteContactPanel extends Panel{
public DeleteContactPanel(String id, final Contact contact) {
super(id);
setOutputMarkupId(true);
final Form form = new Form("form");
form.add(new AjaxSubmitLink("delete") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
service.deleteContact(contact);
onDelete( target );
System.out.println("OK Deleted");
}
});
add(form);
}
public abstract void onDelete( AjaxrequestTarget target );
}
final List columns = new ArrayList();
columns.add(new AbstractColumn(new Model("Delete")) {
public void populateItem(Item cellItem, String componentId, IModel
rowModel) {
Contact contact = ((Contact) rowModel.getObject());
cellItem.add(new DeleteContactPanel(componentId, contact){
public void onDelete( AjaxRequestTarget target ){

Re: Tools for Managing a Wicket Project
What does sonar do? Where can I get "effective java"? That's one of our problems actually. When we go on site in clients we have a hard time going to our centralized tools. I have been looking for an offline bugzilla or trac of some sort. Similar to offline gmail. I'm looking to also setup a distributed maven repository. Per our experience, all our tools become useless when there is no internet connection available, and sadly, most of our clients don't provide on.

How to remove a row from DataTable?
Hey,
I employed AjaxFallbackDefaultDataTable to list contacts.
The last column contains a delete link that I created it this way:
final List columns = new ArrayList();
columns.add(new AbstractColumn(new Model("Delete")) {
public void populateItem(Item cellItem,
String componentId, IModel rowModel) {
Contact contact = ((Contact)
rowModel.getObject());
cellItem.add(new
DeleteContactPanel(componentId, contact));
}
});
public DeleteContactPanel(String id,
final Contact contact) {
super(id);
setOutputMarkupId(true);
final Form form = new Form("form");
form.add(new AjaxSubmitLink("delete") {
@Override
protected void onSubmit(AjaxRequestTarget target,
Form form) {
service.deleteContact(contact);
System.out.println("OK Deleted");
}
});
add(form);
}
When deleting the contact from the database, I want to
remove its row also from AjaxFallbackDefaultDataTable
and display a message.
But I'm not sure how to accomplish this?
I mean how to communicate between DeleteActionPanel
and the DataTable?
Would you please help me?
Thanks for help and time.

Nope. How should wicket decide on that? It's business logic. And so you have to present the dialog (modal window?) yourself. Alternatively you could an javascript alert.

Re: Wicket-Guice: Inject into Session
Hello Igor,
I really like the idea behind Salve.
Are there any open source applications using it, except elephas [1] ?
I already got a lot of inspiration from the elephas source code, but
that project seems to have stalled a bit, right ?
[1] http://code.google.com/p/elephas/
Thanks,
Maarten

May be you can get the database connection from inside the method for
authentication purposes,
Then you haven't got any private or public members which should be
serialized and contains a database connection.

Not a Wicket question but ...
Hey, I understand this is not a Wicket question but I hope I can get some help. Our application uses c3p0 connection pooling. How to set the character encoding for database connection? Even if you aware of how to set the character encoding for Apache DBCP, I will be thankful. The application is built on: Spring 2.5 / Hibernate 3 / Wicket 1.3.5 Thanks. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Need to Understand CheckGroup and Check
The selection variable is a collection or a wicket model with an object of
collection. You can preselect you values by using the same classes there.
Consider this
Form form = new Form( "form" );
String[] someStrings = new String[]{ "Wicket" , "Hibernate", "Maven",
"Spring" };
String[] other = new String[]{ "Wicket" , "Hibernate", "Maven", "Spring",
"C#", "NHibernate" };
CheckGroup group = new CheckGroup( "group", Arrays.asList(
someStrings ) );
ListView stringView = new ListView( "stringView" ,
Arrays.asList( other ) ){
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem item) {
item.add( new Check( "item", item.getModel() ));
}
};
group.add( stringView );
form.add( group );
add( form );
Here the someStrings will be checked, that is ( "Wicket" , "Hibernate",
"Maven", "Spring" ). NHibernate and C# will not be checked.
Hope this helps.
