Hi Wicket Team and Wicket Mailinglist!
As this is my first post on this list, I would like to introduce myself.
My name is Sebastian and I am working on a university project, comparing
Java web frameworks. As you might guess, my primary topic is the Wicket
framework ;). I am not what one would call a programmer or coder, I
guess.
Rather someone familiar with the underling concepts, but sometimes a bit
lots with the actual implementations of a certain language. So please
excuse
me, if my questions are stupid ;).
My problem at this moment is the following. I need to implement a feature
in wicket that lets me upload images to a webpage and then use those
images
to be displayed on certain pages. It doesn't really matter if the images
are
stored on the file system or in a database. I am not looking for a
solution
to an explicit problem but rather for a best practice that shows how the
wicket framework supports such a feature.
I have tried to read up on anything I could find addressing such a
feature. But everything I got so far is either way beyond my scope of
understanding, not offering enough to archive the goal or just not
working
as I understand it should.
I have tried to read the example in the wiki (
http://www.wicket-wiki.org.uk/wiki/index.php/*UploadDownload*http://www.wicket-wiki.org.uk/wiki/index.php/UploadDownload),
but I can not really follow it. Too many libraries used that are not
included and overall to confusing for a non professional like myself.
I did understand the example for the upload in the wikiexamples though.
No
problems writing files to disk or even to database, following that
example
code.
My attempt to store images in the Database is looking something like
this:
To write to the Database, I use this code sniped:
public final void onSubmit()
{
try
{
// get the content of the upload field
final FileUpload upload_image =
upload.getFileUpload();
// create a byte array of the uploaded item
byte[] bild = upload_image.getBytes();
if(upload_image != null)
{
**write byte[] to database**
}
}
catch (Exception e) { }
}
So far so good. Got my byte array stored. The source file is a jpeg
image.
I am not sure if I miss some kind cast here to let the system know what
*sort* of byte array it should use.
When I try to retrieve the image from the database, I use the following
code:
public ResourceReference getImage()
{
return new ResourceReference(some.class, bild)
{
public BufferedDynamicImageResource newResource()
{
try
{
// get the byte[] from DB
byte[] bild = a.getBild();
// create a buffered image template
BufferedDynamicImageResource resource = new
BufferedDynamicImageResource();
BufferedImage image = new BufferedImage(200,
200, BufferedImage.TYPE_INT_RGB);
// transform the byte[] back to an image (does it work that way? How does
// java know it was a jpeg before and not a gif for example?)
java.awt.Image i = Toolkit.getDefaultToolkit
().createImage(bild);
// convert image to buffered image
image.getGraphics().drawImage(i, 0, 0,
null);
Graphics g = image.getGraphics();
g.drawImage(i, 0, 0, null);
g.dispose();

Re: [Wicket-user] creating a javascript prompt component
Okay, that could work, but in my case I'm not wrapping each led-sign element in a form. What I've come up with, after looking at the Link class, is registering a new IRequestListener, my PromptResultListener.Then, when rendering i get the url for the listener and append a parameter, like this: String url = "" Then I get the p value from the request and dispatch that. It feels a bit hacky but it looks like the way the Ajax stuff is working right?Maybe in the end I'll conclude that I need a form element for all of this after all, but so far it seems to be working like I want it :) Thanks,HugoOn 8/21/06, Martijn Dashorst [EMAIL PROTECTED] wrote: Probably the simplest way to go is to create a panel with a hiddenfield, or a textfield with style='display:none', and a label. the restis left your _javascript_ guru-ness.wicket:panelspan wicket:id=text >'bar');text comes here/spaninput wicket:id=value type=hidden id=foo //wicket:panel MartijnOn 8/20/06, Hugo Visser [EMAIL PROTECTED] wrote: Hi, I'm toying around with wicket some more and I'm working on a kind of editor application for my led-sign which I have at home.

this is Java - we have no pointers :P
basically, if you want to get the data from a file you do it a bit different
as from a DB stream, if you look here, youll see the basic behind IO here:

Re: [Wicket-user] How to Implement Looping in wicket
for records in a database it is better to use a Repeater then the Listview.Especially if you have call backs (like edit or delete to it)because you have to specify your own model then that holds the record of the database.

[EMAIL PROTECTED] wrote: Hi Wicket Team and Wicket Mailinglist!
As this is my first post on this list, I would like to introduce myself. My name is Sebastian and I am working on a university project, comparing Java web frameworks. As you might guess, my
primary topic is the Wicket framework ;). I am not what one would call a programmer or coder, I guess. Rather someone familiar with the underling concepts, but
sometimes a bit lots with the actual implementations of a certain language. So please excuse me, if my questions are stupid ;).
My problem at this moment is the following. I need to implement a feature in wicket that lets me upload images to a webpage and then use those images to be displayed on certain pages. It
doesn't really matter if the images are stored on the file system or in a database. I am not looking for a solution to an explicit problem but rather for a best practice that shows how the wicket framework
supports such a feature. I have tried to read up on anything I could find addressing such a feature. But everything I got so far is either way beyond
my scope of understanding, not offering enough to archive the goal or just not working as I understand it should. I have tried to read the example in the wiki (
http://www.wicket-wiki.org.uk/wiki/index.php/*UploadDownload*http://
www.wicket-wiki.org.uk/wiki/index.php/UploadDownload), but I can not really follow it. Too many libraries used that are not included and overall to confusing for a non professional
like myself. I did understand the example for the upload in the wikiexamples though. No problems writing files to disk or even to database, following that
example code. My attempt to store images in the Database is looking something like this:
To write to the Database, I use this code sniped: public final void onSubmit() {
try { // get the content of the upload field
final FileUpload upload_image = upload.getFileUpload(); // create a byte array of the uploaded item
byte[] bild = upload_image.getBytes(); if(upload_image != null)
{ **write byte[] to database** } }
catch (Exception e) { } } So far so good. Got my byte array stored. The source file
is a jpeg image. I am not sure if I miss some kind cast here to let the system know what *sort* of byte array it should use.
When I try to retrieve the image from the database, I use the following code: public ResourceReference getImage()
{ return new ResourceReference(some.class, bild) { public BufferedDynamicImageResource newResource()
{ try { // get the byte[] from DB
byte[] bild = a.getBild(); // create a buffered image template BufferedDynamicImageResource
resource = new BufferedDynamicImageResource(); BufferedImage image = new BufferedImage(200, 200, BufferedImage.TYPE_INT_RGB
); // transform the byte[] back to an image (does it work that way? How does // java know it was a jpeg before and not a gif for example?)
java.awt.Image i = Toolkit.getDefaultToolkit ().createImage(bild);// convert image to buffered image
image.getGraphics().drawImage(i, 0, 0, null);Graphics g = image.getGraphics
(); g.drawImage(i, 0, 0, null); g.dispose();
// return the image resource.setImage(image); return resource;
} catch (Exception e) { } } };

Re: [Wicket-user] How to Implement Looping in wicket
Using the repeater examples, the looping is done by the framework as it walks the Iterator that's returned by the IDataProvider.iterator() implemention (ContactDataProvider).

Re: [Wicket-user] How to Implement Looping in wicket
the looping itself is implemented by the repeater component - DataView,GridView,DataTable,RefreshingView,ListView,Loop,etc. the populateItem method is called for every element in the iterator/list and builds the component hierarchy to represent that element. -IgorOn 8/23/06, sathya81 [EMAIL PROTECTED] wrote: Hi,I was going through the repeater examples , i just wanna know how can iimplement looping in wicket, for example i have vector populated with somerecords fetched from a database , now how can loop through the vector and display the records in the html page?

[Wicket-user] set focus on TextField
Hi, I've got a panel for adding dates with an add link, when the link is clicked I replace it with a small form with a single TextField (input type=text..). What I would like to do is to set focus on the textfield when I switch panels. Is there an easy solution for this? I guess I could add an onLoadEvent but that would imply that my panel would add an onLoad-script to the page, which seems complicated. /Mats - Using Tomcat but need to do more?

[Wicket-user] getParent() is null
I am using a special IFeedbackMessageFilter to basically scope feedback messages to a particular component and all of it's children. The problem I am having (and this problem has existed for quite awhile, I just haven't had the time to look into it all that much) is that in some circumstances the children that are creating the feedback messages cannot resolve the parent that the actual feedback panel is tied to. IE:
Parent
- ListView
- ListItem
- Reporter (creates error message via error() call)
Parent is the component I assign to the FeedbackPanel to scope all of the displayed messages to the Parent itself and any of it's children via this:
@Override
protected IFeedbackMessageFilter getFeedbackMessageFilter()
{
return new IFeedbackMessageFilter()
{
public boolean accept(FeedbackMessage feedbackMessage)
{
return parent == feedbackMessage.getReporter() || parent.contains( feedbackMessage.getReporter(), true );
}
};
}
The problem is that the parent.contains( ... ) is failing. I debugged the component tree by doing this in the debugger:
feedbackMessage.getReporter().getParent().getParent().getParent()
This returns a ListItem component in which the parent is null. Meaning the reporter - parent link is broken. In what circumstances can a ListItem's (or any component for that matter ) parent be null?

I personally dislike their UI. The technology might be nice and well but they need some UI guy to clean things up. Just my 2 cents.

Re: [Wicket-user] getParent() is null
I think i've fixed the problem. The problem was I was overriding getVisible() and checking for the presence for feedback messages there, but at that point the hierarchy is already altered. After looking over the source code, I noticed that IFeedback instances get updateFeedback() called before the hierarchy is rebuilt. So I did a setVisible() from within updateFeedback and everything seems to work fine now. Aaron On Wed, 2006-08-23 at 18:28 -0700, Aaron Hiniker wrote: - Using Tomcat but need to do more?
