Hi, if you haven't done it yet you should have a look at WicketStuff data store projects: https://github.com/wicketstuff/core/tree/master/datastores-parent this should give you some good ideas.

Re: SessionStore on database
Hi, There are two options I'm aware of: - You can use a session manager in your application server that stores your session in the database. I.e. Tomcat's JDBC store. - You can use Spring Session with a JDBC store I recently implemented Spring Session for Wicket with Redis as a backing store. There are minor issues with page locking that require some custom code, but otherwise it works fine.

@Sebastien, thanks - works. I had started this way, but didn't get the ListView becoming instantiated. Trying again now worked fine.

Re: Webpage does not refresh when ListView is based on a List supplied by a database
Hi,
PropertyModel pm = new PropertyModel(this, dataList);
ListListData werte = (ListListData) pm.getObject();
final ListView listView = new ListView(listentries, werte )
You need to pass a model to the list view:
final ListView listView = new ListView(listentries, new
PropertyModelListListData(this, dataList))
Also please note that you should avoid unwraping a model (calling
#getObject) in the constructor...
Hope this helps,
Sebastien.

Hi, FileUploadField works with IModelFileUpload only. Usually you keep the fileUpload in your component and explicitly do something with its bytes in your #onSubmit().

new IModelListlt;FileUpload() {
public ListFileUpload getObject() {

}
public void setObject(ListFileUpload object) {

because i am getting error java.lang.NullPointerException when i use

the solution works when i use diffrent object type like these

how to use PropertyModel for saving image to database
hi, i have a file upload process for image. fileupload.java https://gist.github.com/cortix/9079660 User1.java https://gist.github.com/cortix/f5fbc0a137d6acfa9b40 fileupload.html https://gist.github.com/cortix/9082148 i got this error https://gist.github.com/cortix/9079743 ... final FileUploadField fileUpload = new FileUploadField(fileUpload,new PropertyModel(user1, photo)); form.add(fileUpload); ... i think i should change my ProperyModel or the method for images to save database because in my pojo class my object type is byte[]... When i use this way, i get error... i am thinking if this PropertyModel change, i can fix this problem but i don't know how can i use this PropertyModel for byte type..

Paging and excessive database access (repeaters)
Hi, I'm following the example in the repeaters section for paging through large amounts of data: http://www.wicket-library.com/wicket-examples-6.0.x/repeater/wicket/bookmarkable/org.apache.wicket.examples.repeater.PagingPage Based on the example and how I've had to implement this there is a lot of data access. First is in the ContactDataProvider. The function iterator queries for the set of data that will be displayed. Next, all the objects that are returned need to be wrapped in a DetachableContactModel. The load mechanism here then loads each individual object from the datastore. In the example, the data is in memory. In a real world scenario the data is likely to be remote and this setup could have a significant performance impact. Is there some way to cut out some of the data access? For example, can I get rid of DetachableContactModel and just use the data retrieved through the ContactDataProvider? Thanks, Daniel
RE: Paging and excessive database access (repeaters)
Take a look at the Apache Wicket Cookbook: http://www.packtpub.com/article/apache-wicket-displaying-data-using-datatabl e It caches the data for the request. Also others have implemented such caching mechanism: http://opensource.55minutes.com/apidocs/fiftyfive-wicket-all/4.0/fiftyfive/w icket/data/DtoDataProvider.html I usually only cache the count() since it depends on what's in the cell after all (especially for the foreign keys when you want to display a name and not an ID). ~ Thank you, Paul Bors -Original Message- From: Daniel Watrous [mailto:dwmaill...@gmail.com] Sent: Tuesday, June 11, 2013 11:56 AM To: users@wicket.apache.org Subject: Paging and excessive database access (repeaters) Hi, I'm following the example in the repeaters section for paging through large amounts of data: http://www.wicket-library.com/wicket-examples-6.0.x/repeater/wicket/bookmark able/org.apache.wicket.examples.repeater.PagingPage Based on the example and how I've had to implement this there is a lot of data access.

Re: Paging and excessive database access (repeaters)
This example is not quite optimized. The DetachableContactModel's
constructor is
public DetachableContactModel(Contact c)
{
this(c.getId());
}
but it should be:
public DetachableContactModel(Contact c)
{
this(c.getId());
setObject(c);
}
The way it's done in the example although the model is given the contact,
it stores only its id and needs to load it from the database in order to
access it, even while rendering the table. The way I suggest the model is
given the contact and does not need to load it.
So, the way it's done in the example database access is as follows:
- a list query to get the contacts for a given page
- n queries by id, one for each row
The way I'm suggesting database access is as follows:
- a list query to get the contacts for a give page
- no other queties
If the row contains say a link column that accesses the row model in the
ajax click, then you will see an additional database access by id when the
DetachableContactModel is attached.

Re: Paging and excessive database access (repeaters)
So what I'm hearing is that I have to use the Detachable model, but that I
can build in some caching to prevent unnecessary datastore access.
Thanks.

Using AutocompleteTextField with database entries (without a converter)
Hello, I don't know what is the best way of impleting that in Wicket That's my use case: - the user has to select a customer in a field of a form, - he starts to type some characters, - the list shows some possibilities based on a database request using the first and last names, the email, ... - then he selects one item in the list, - the field just shows few informations (Last Name for exemple). I don't want to use a converter because the data in the field could eventually match more than one entry in the database. I can give more context in the list to make the user be sure of his selection. When the selection is made, I can put a title so that on a mouse over event the user visualize the full information on the customer selection. The best solution would be to use the database id of the customer as a key during the selection phase. I don't know what is the best way of implementing this behaviour. Thanks a lot for any ideas, Gaetan,

Need some help creating dynamic resources from database-inputstream please!
Hi, in my project I use a CouchDB with files as attachments. Currently I have a page that makes those attachments available via a ResourceLink. What I do when creating that page is: - I read all attachments (I get them as an InputStream), - create a byte[] out of it, - create a static Wicket ByteArrayResource - and put the link to that resource on the page. That works for smaller files, but a huge problem is of course: it's static, and I get memory problems if the attachments get too big. Also, currently obviously each session does this. What I would like to do instead is: - create Resources that will load my attachments dynamically if the link is clicked, - and add ResourceLinks to those resources on my page instead. - If possible, maybe deliver the attachments directly from the InputStream my CouchDB delivers, so I don't have to have any static byte-arrays on my server. That way I could make the page load immediately and deliver attachments only if required. I've wrapped my head around IResourceStreams, but I just can't see clear anymore and am confused about how to create those dynamic resources (also because some old examples don't work anymore with Wicket 1.5 or 6beta3). I'd be very thankful for a short example, or a hint about how to design this. Thank you!

Re: Need some help creating dynamic resources from database-inputstream please!
Hi, thanks for for quick answer! I already played around with ResourceStreams, but my problem was that I couldn't do the bridge from a Stream to a Resource with a URL. I should add, I'm not offering my ByteArrayResources as a download. I pass the content-type and filename, and (with the help I got from a user here) return it as INLINE. So, when the user clicks, the browser opens the filetype if it can (e.g. a picture, or a PDF with a built-in viewer). Also (and that's important) I then have a real URL which I can pass to Javascript functions. E.g. if the attachment is an mp3 or a video, I additionally use the URL of the ResourceLink to open a custom flash-player (JW Player).. I need a solid URL for that, for that session. When I played around I just couldn't manage to get that kind of URL when I worked with Streams. But I will give it another try.

Re: Need some help creating dynamic resources from database-inputstream please!
I think I just made a huge step forward by overriding getData() of
ByteArrayResource. I've read that in the documentation before, but at that
time was too deep into the concept of resources that I didn't get it (I'm
completely new to Wicket).
So, right now it works that I read my attachment, convert it into a
byte-array and deliver it, only when the link is clicked. I still get a URL
I can use for other functions (pass a .mp4-ByteArrayResource to a JW Player
instance e.g.) No creating of static resources at page-load anymore.
Next step would be to skip the byte-array completely. How could I do my own
Resource that delivers the data as a stream, but has the same functionality
otherwise (usable in some kind of Link so that I can get the URL)?
Something like
Resource attachmentResource = new WebResource() {
@Override
public IResourceStream getResourceStream() {
// return my stream somehow
}
}
doesn't work anymore if I'm not mistaken.
Appreciate your help so far!

before is all the different obsolete examples and tutorials for older
versions. The problem is, when you are new to Wicket, you are still
figuring out how stuff works, and when trying to implement certain things
you hit road-blocks because those code-examples don't work anymore, and you
don't know why.
Here is my solution: http://pastebin.com/yQFh5gk8
This is how I'm doing it for now, returning the stream on-the-fly from the
database when the ResourceLink is clicked.
However, I get huge stacks of exceptions now: *java.lang.IllegalStateException:
Header was already written to the resonse!*
*

Here is an example, I get lots of those: http://pastebin.com/5LuDqp5a
Thanks! I'm almost there I think :)

I think I just made a huge step forward by overriding getData() of
ByteArrayResource. I've read that in the documentation before, but at that
time was too deep into the concept of resources that I didn't get it (I'm
completely new to Wicket).
So, right now it works that I read my attachment, convert it into a
byte-array and deliver it, only when the link is clicked. I still get a URL
I can use for other functions (pass a .mp4-ByteArrayResource to a JW Player
instance e.g.) No creating of static resources at page-load anymore.
Next step would be to skip the byte-array completely. How could I do my
own Resource that delivers the data as a stream, but has the same
functionality otherwise (usable in some kind of Link so that I can get the
URL)? Something like
Resource attachmentResource = new WebResource() {
@Override
public IResourceStream getResourceStream() {
// return my stream somehow
}
}
doesn't work anymore if I'm not mistaken.
Appreciate your help so far!

Hi, thanks for for quick answer! I already played around with
ResourceStreams, but my problem was that I couldn't do the bridge from a
Stream to a Resource with a URL.
I should add, I'm not offering my ByteArrayResources as a download. I
pass the content-type and filename, and (with the help I got from a user
here) return it as INLINE. So, when the user clicks, the browser opens the
filetype if it can (e.g. a picture, or a PDF with a built-in viewer).
Also (and that's important) I then have a real URL which I can pass to
Javascript functions. E.g. if the attachment is an mp3 or a video, I
additionally use the URL of the ResourceLink to open a custom flash-player
(JW Player).. I need a solid URL for that, for that session.
When I played around I just couldn't manage to get that kind of URL when
I worked with Streams. But I will give it another try.
PS: I found this example a while ago, and wanted to implement my own
IResourceStream to fetch the attachments from the DB, but the example is
outdated and I couldn't figure out how to do it with a newer version of
Wicket: http://goo.gl/imGrl

Hi, in my project I use a CouchDB with files as attachments. Currently I
have a page that makes those attachments available via a ResourceLink.
What
I do when creating that page is:
- I read all attachments (I get them as an InputStream),
- create a byte[] out of it,
- create a static Wicket ByteArrayResource
- and put the link to that resource on the page.
That works for smaller files, but a huge problem is of course: it's
static,
and I get memory problems if the attachments get too big. Also,
currently
obviously each session does this.
What I would like to do instead is:
- create Resources that will load my attachments dynamically if the
link
is clicked,
- and add ResourceLinks to those resources on my page instead.
- If possible, maybe deliver the attachments directly from the
InputStream my CouchDB delivers, so I don't have to have any static
byte-arrays on my server.
That way I could make the page load immediately and deliver attachments
only if required.
I've wrapped my head around IResourceStreams, but I just can't see clear
anymore and am confused about how to create those dynamic resources
(also
because some old examples don't work anymore with Wicket 1.5 or 6beta3).
I'd be very thankful for a short example, or a hint about how to design
this. Thank you!
Next database key pre-filled in form and associated with PropertyModel returns null
G'day Short form: how do I pre-fill a form field with the dynamic value of the next free database key Long form: I'd like to pre-fill a form field with the value of the next free database key. I can do this by associating the form input field with a static model of a string value and replacing the field in the form each time the next key value changes. Works, but hardly elegant. So I've associated the input field with a (dynamic) property model. Because the next key value isn't a database field I've created a new class (called State) with a field for the next free database key. The property model I've associated with the form field points to that attribute of State. As each new database row is created I manually update the value of the next free key in State. This value then finds its way into the form when it is next displayed. So far so good. Each time the form is displayed I can see the correct next free key value pre-filled into the form as expected. But when the form is submitted and I do a getModelObject() on the form the gotten object has null in the field that should contain the next free database key. All the other fields are correctly received from the form. (This is true more generally - in more complex forms all the form fields that are not associated with State are correctly received from the form. All those that are associated with State are null.) What is weird is that if I do: Account account = getModelObject(); // returns null in field accountNumber which is associated with State account.setAccountnumber(Integer.parseInt(accountNumber.getInput())); // Gets and sets the pre-filled value then I get the desired result i.e. field accountNumber of account is set to the pre-filled value. So there is no doubt that form field has the desired value - I can see it, and getInput() gets it. But getModelObject() (which I would be expecting to call getInput() under the covers) doesn't get the pre-filled value. I suspect this is a question of understanding about models in general. (I've looked at whether I should add my PropertyModel in some way to the LoadableDetachableModel that is associated with the form but the water got rather deep rather quickly.)

Re: Next database key pre-filled in form and associated with PropertyModel returns null
How do you determine which next key is available? If two users open the form at the same time will they see the same key? If so, then you need to handle errors from concurrent form submissions with the same key. Which means for one of these concurrent requests you will have to issue a different key and show it to the user after the form was submitted. So, why not show the key after form submission all the time?

Re: Next database key pre-filled in form and associated with PropertyModel returns null
G'day In part the question was based on a misunderstanding which I have now overcome. I thought that all the columns of the database table had to be present in the form as form fields. But that is not the case. So any column whose value I know ahead of time I don't present on the form - I just give them values in the code after the user submits the form. I also came to the same conclusion about the database keys. So that reduces the question to form fields that I want to pre-fill with a (context-dependent) default value but whose value I allow the user to change. I can pre-fill the fields using a Property model as described in the initial post, but such values are null after the GetModelObject(). Is this a misunderstanding about models - that the GetModelObject won't get the values of form fields that are linked with a model other than the model the form is linked with. Seems reasonable, except that if the pre-filled fields are linked with a static model instead of the (dynamic) PropertyModel the form values are retrieved correctly by GetModelObject().

G'day In part the question was based on a misunderstanding which I have now overcome. I thought that all the columns of the database table had to be present in the form as form fields. This meant that I had to pre-fill values for the key fields. This indeed has the difficulties that you raise. But it is not the case that all the columns need to be in the form. So I no longer show the key fields but provide values for their columns after I retrieve the form with GetModelObject(). That side-steps the difficulties you mention. And, yes, I now need in some cases to show the user the key value that was generated. I've done that crudely with a form that becomes visible after the database row has been successfully created. But I will replace that with a reusable model window in due course. (Unless Wicket 5 has a simpler dialog box feature that I haven't yet discovered. I don't want to do the dialog box in Javascript). But that still leaves the question of why the pre-filled values weren't retrieved by the GetModelObject(). Their values are associated with a model other than the model that is associated with form - is that the reason ? Seems reasonable, except that if the pre-filled form fields are associated with a static model (rather than the (dynamic) PropertyModel that I currently use) then the pre-filled values are correctly retrieved by GetModelObject().

Re: LoadableDetachableModels for a ListView ( database with Cayenne)
Hi Vineet,
public LoadableDetachableModelYourClass load(final Long xxx) {
LoadableDetachableModelListYourClass model = new
LoadableDetachableModelListYourClass() {
protected YourClass load() {
try {
ListYourClass list = get your liste here( xxx )
return list
} catch (YourException e) {
}
}
};
return model;
}
IModelListYourClass model = load( x );
new ListViewYourClass(id, model) ;
That is ok for a small list.
And if you have to handle large lists, you should use a Dataview with
DataProvider.

guestbook application with database update
I'm creating a small app based on the guestbook:
http://www.wicket-library.com/wicket-examples/guestbook/?1
In the guestbook app, the page view is updated every time a new
comment is added. The variable commentList is initialized at the top
like this
private static final ListComment commentList = new ArrayListComment();
// Add commentListView of existing comments
add(new PropertyListViewComment(comments, commentList)
{
@Override
public void populateItem(final ListItemComment listItem)
{
listItem.add(new Label(date));
listItem.add(new MultiLineLabel(text));
}
}).setVersioned(false);
I wanted to use a database instead, so I made the following changes
private ListMovie movieList = new ArrayListMovie();
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
movieList = session.createQuery(from Movie).list();
session.getTransaction().commit();
// Add commentListView of existing comments
add(new PropertyListViewMovie(movies, movieList) {
@Override
public void populateItem(final ListItemMovie listItem) {
listItem.add(new
TextFieldString(name).setType(String.class));
listItem.add(new DropDownChoiceCategory(category,
Arrays.asList(Category.values()), new
EnumChoiceRendererCategory(this)));
listItem.add(new Label(rating));
}
}).setVersioned(false);
With this change, all the items in the database come up when the page
first loads, but not after each new item is added to the database. I
have to clear out the URL and load the page fresh to see what has been
added since the last fresh load.
I did try resetting movieList in the onSubmit function to load the
current database items into the variable movieList, but that still
doesn't update the list.
Any idea how to update movieList after each new item is submitted.

Re: url for images from database
This works for me, in case anyone's interested in a simple solution.
I have a ListView which outputs Books (their Title, Author, etc., and also a
Book Image which is a JPG stored in a DB), all per row, based on a POJO
called Book which stores all this info. Book also has a byte[] for the
Image field.
add(new ListView(books, books) {
@Override
protected void populateItem(ListItem li) {
Book b = (Book) li.getModelObject();
li.add(new Label(bookId, b.getBookId().toString()));
li.add(new Label(bookTitle, b.getBookTitle()));
li.add(new Label(bookAuthors, b.getBookAuthors()));
li.add(new Label(bookPrice,
Integer.toString(b.getBookPrice(;
// add book image
ByteArrayResource resourceBookImg = new
ByteArrayResource(image/jpeg, b.getBookImg());
TechBooksApplication.get().getSharedResources().add(img +
li.getIndex(), resourceBookImg);
Image imgBook = new Image(bookImg, resourceBookImg);
li.add(imgBook);
}
});
Maybe this isn't quite what Miroslav wants, but for me I don't need to
re-format URLs, so this is working fine for me.

RE: url for images from database
I have the exact same problem. I have Images coming from the DB, along with other stuff, and I need to display them, per row, as , similar to how Amazon.com lists their books next to book title, etc. Is there an easy way to do it? Very common problem. Can someone show what the HTML and Java should look like to support this dynamic image display?

database
Hi folks, I'm newbie in wicket. I would like to make my wicket app to store images in database. No problem but I don't know how to configure tomcat + wicket for database.

Re: database
Hi! Make a separate project for wicket app and database module, so you don't need to worry about where to place what in what combination. This way you can share you db module with both your wicket project and swing project. Also you should keep swing project and wicket project sparate. ** Martin 2011/6/4 Miroslav F. mir...@seznam.cz: Hi Martin, ok, so can I use Hibernate as in my Swing apps?

How to initialize database with Spring in wicketTester/JUnit class?
Hi all,
I have a Wicket application which works with Spring, JPA and Hibernate. I
used this archetype to create the project (archetype found through Wicket
More archetype page) :
mvn archetype:generate -B -DarchetypeCatalog=
http://legup.googlecode.com/svn/repo/archetype-catalog.xml-DarchetypeArtifactId=wicket-spring-jpa-archetype
-DarchetypeGroupId=com.jweekend -DarchetypeVersion=0.8.4
-DgroupId=com.mycompany -DartifactId=mycompany -Dversion=1.0-SNAPSHOT
-Dpackage=com.mycompany
in the project generated, there is a class DataInitialiser which initialize
database and which is called by applicationContext.xml :
bean class=fr.statlife.protoE4N.DataInitialiser
init-method=dataInit
property name=serviceMembre ref=serviceMembre/property
property name=serviceLienBaseE4N ref=serviceLienE4N/property
/bean
it's work well when I test my application manually, but database is not
initialized when I used WicketTester.
This is the setup method used with wicket tester :
public class TestStory04 {
protected WicketTester tester;
@Before
public void setup()
{
final ApplicationContextMock acm = new ApplicationContextMock();
ServiceIdentification serviceIdentif =
Mockito.mock(ServiceIdentification.class);
acm.putBean(serviceIdentif, serviceIdentif);
ServiceInscription serviceInscription =
Mockito.mock(ServiceInscription.class);
acm.putBean(serviceInscription, serviceInscription);
tester = new WicketTester(new WicketApplication(){
/* (non-Javadoc)
* @see
fr.statlife.protoE4N.WicketApplication#getGuiceInjector()
*/
@Override
protected SpringComponentInjector getSpringInjector() {
return new SpringComponentInjector(this, acm, true);
}
});
}
[some tests]
}
In setup method, I tried to add
DataInitialiser dataInitialiser =
Mockito.mock(DataInitialiser.class);
acm.putBean(initData, dataInitialiser);
try {
dataInitialiser.dataInit();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
but it doesn't work : database is not initialized.
So how can I initialize my database ?
Thanks

Re: How to initialize database with Spring in wicketTester/JUnit class?
My mistake : I tried to do integration test with mocks...
I think I have to use @ContextConfiguration instead
ApplicationContextMock...

Re: IStringResourceLoader database implementation
Thanks, My concern is also name component collition. The org.apache.wicket.resource.loader.ComponentStringResourceLoader iterates over the component stack to check for the values but that could leed to 10 times per text string and it would be a heavy load even if I implemented some sort of cache. ( Or used wickets in Localizer ). How did you go about name collition without sinking the database? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/IStringResourceLoader-database-implementation-tp3533408p3534888.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
