Re: [Wicket-user] library example using Shades for O/R mapping
I also read your blog, and it sounds very interesting.
Just a quick question (probably should've done so on the blog though):
Does it hold that after getting a book and author from the results that:
aBook.getAuthor() == anAuthor
and/or
aBook.getAuthor().equals(anAuthor)
?

have

I understand your position... Shades is your hobby, pet project and it would be nice that people find it helpful. I think there is a market for it, as other people have come to the same conclusion. At my company at least I and a collegue of mine are very interested in trying out http://www.simpleorm.org/ It seems like this is very similar to your proposition. Their goals are about the same but they took a different direction. The name 'Shades' is not a pun directed to 'The Shades', from Terry Pratchett's Discworld, would it? :) Martijn On 8/26/06, Geoff hendrey [EMAIL PROTECTED] wrote: Sure - but honestly I don't want to convince anyone they need Shades.

Ohh my god yes
I ran into all these problems in JDOMax, and they are
all solved in Shades.
I won't drop the name, but some very influential
person on EJB and JDO specs now believe that exposing

I agree -- you will notice shades has no methods to
retrieve an object by identity. Shades only has
queries.

a much more fluid concept in Shades, due to the

implement on the fly as an anonynmous inner class.

Re: [Wicket-user] library example using Shades for O/R mapping
Most ORMS have 2 kinds of L1 caching:
1) caching of compiled queries
2) caching of POJOs, where the cache is keyed by
identity
Shades does (1).
Shades does not do (2).
I found that the L1 cache was actually redundant. Why?
Because most modern frameworks, like Wicket, take the
pojo, and hold onto it. The caching is implicit in the
application. In JDO, the L1 cache is implemented using
WeakHashMap. So it's sort of a pseudocache anyway. We
(the JDO EG) actually had a long debate about changing
some of the JDO method names to not use the term
cache. If your application does not keep a reference
to the pojo, the pojo doesn't stay in the cache. What
kind of cache is that? :-)

Re: [Wicket-user] library example using Shades for O/R mapping
No doubt L2 caching can speed up apps. Most databases
implement caching already. With L2 cache comes another
set of problems, and when you get deep enough into
them, you may wish you had not used the L2 cache, but
simply relied on effective caching in the database. On
the other hand, many L2 caching layers are out there,
and can be easily used with a pojo, whether the pojo
was retrieved by shades or not.
WeakHashMap will discard your key/val pair during the
first garbage collection cycle after your program
holds no references to the key.An entry in a
WeakHashMap will automatically be removed when its key
is no longer in ordinary use...from the javadoc.

Re: [Wicket-user] library example using Shades for O/R mapping
I haven't profiled L2 caching done by database, if someone has I'd
really be interested in results.
Anyway, I wouldn't use WeakReference for caching, SoftReference seems to
be better alternative.

[Wicket-user] wicket:head in page template...
Hi, In some of the documentation it is mentioned that wicket:head is not supposed to be used in pages (e.g. http://www.wicket-wiki.org.uk/wiki/index.php/Including_CSS_resources). However, if I use markup inheritance for all my pages, then the base markup will contain a head section. This head section could be insufficient since I might need some special css or javascript for some pages. To do this, using wicket:head in those pages to include the extra content (e.g. style sheets or javascript) solves the problem. Therefore, I think wicket:head in pages is still useful. Is this a good use of wicket:head or should I use some other means to add specific content to the head section for some pages? Cheers Erik - Using Tomcat but need to do more?

Re: [Wicket-user] library example using Shades for O/R mapping
the spec says:
When instances are queried,
navigated to, or modified, instantiation of instances
and their fields and garbage collection
of unreferenced instances occurs without any explicit
control
So that means that whatever implementation is used to
map between identity and Object, it can't be a hard
reference. So pojo's get garbage collected out of the
L1 cache. So that lends even more weight to your
statement that you need an L2 cache. Half the time the
implementation is going out to the DB to repopulate
the cache (like if you have a pojo and it's in a
wicket session that gets serialized, welll whoops, the
JDO implementation is going to query the DB to
repopulate the cache the when you deserialize and do
getObjectById).

[Wicket-user] Wicket 1.2.2 available
The Wicket team is proud to announce the availability of Wicket 1.2.2, the second maintenance release for Wicket 1.2.This release contains several bug fixes, and some major improvements by receiving backported components from our
2.0 branch, most notably: modal window support and a fully ajaxified Tree and TreeTable. These components can be found in the Wicket Extensions package.Wicket 1.2.2 is a drop-in replacement for Wicket 1.2 and Wicket
1.2.1, however we urge you to test before you put things into production, especially if you are using prototype.js and Wicket ajax. We have put a lot of effort into testing the compatibility between Wicket ajax and prototype, but you may never be sure.
DownloadThe Wicket 1.2.2 release can be downloaded from the sourceforge.net servers at a location near you. Follow the next link to go to the downloads page:
http://sourceforge.net/project/showfiles.php?group_id=119783RoadmapThe Wicket roadmap is as follows (no dates available). Our main development effort will focus on Wicket 2, which will be Java 5 based. For providing support to those projects already in production or that are bound to Java
1.4, we will continue development of Wicket 1.x, which will consist mainly of backported functionality from Wicket 2 and bug fixes. The next minor release for these projects will be Wicket 1.3.
List of changes in Wicket 1.2.2o Wicket - Added Application.exists() and Session.exists() to check for existence of threadlocals - Backported 2.0 CompressedPackageResource and CompressedPackageResourceReference
- Backported 2.0 _javascript_ console (much faster) - New wicket-ajax _javascript_ with support for channels - default validator rethrows any exception as ConversionException - Opened up MarkupParser so that it can be used by other components
- Close input stream in AbstractResourceStream.asString() - CryptedUrlWebRequestCodingStrategy is spammy - Support for showing expired page from an AJAX request, through identification. This replaces the fix for issue 1528244 in a more generic way.
- Error page no longer alters the url so the refresh button will rerun the code that caused the error - RestartResponseAtInterceptPage(Class) will now generate bookmarkable urls - Implemented ajax support for palette
- Support for conditional comments such as lt;!--[if IE]gt;..lt;![endif]--gt; - AjaxLink can now be attached to anything that supports onclick - Link.getBefore/AfterDisabledLink() now behave properly when overridden
- Dynamic resource support for portlets - Navigate to another page from ajax request (in other words break out of the ajax request). Like: public void onClick(AjaxRequestTarget target){ setResponsePage(LinksPage.class
); } - Render number of rows properly on ListChoice o Wicket Extensions - Backported AJAX header contribution code from 2.0. - Backported 2.0 Modal Window - Backported 2.0 Ajax enabled Tree and TreeTable
- Fixed markup-id issue of datepicker so it works with ajax - Backported 2.0 wicket-ajax.js compatible version of the autocompleteHave fun!- The Wicket Team-- Download Wicket
1.2.2 now! Embed Wicket components in your portals!-- http://wicketframework.org

Re: [Wicket-user] Fom validation
thanks. it's working, but like this, i always have to overide the
Form.validate() and it won't work with normal Form. What do you think about
this solution:
class MyComponent extends Panel {
private IFormValidator formValidator;
setValidation(...){
formValidator = new IFormValidator(){
public FormComponent[] getDependentFormComponents() {
return null;
}
public void validate(Form form) {
if (checkerrors()) {
error(foo);
}
}
};
}
protected void onBeforeRender() {
if(formValidator != null){
Form form = (Form) findParent(Form.class);
form.add(formValidator);
}
super.onBeforeRender();
}
}

[Wicket-user] New subversion repository structure
All, We have had a long and interesting discussion about what to do with our releases and our repository. As you know, we are working in a forked mode: wicket 2.0 is under active development, and we also provide support for wicket 1.2 (1.2.2 has just been released), and will start work on 1.3 soon (if it hasn't started already). This message tries to clarify where you can find stuff in our subversion repository. If you look at the repository you will see the following root structure: /trunk/ /branches/ /tags/ /releases/ trunk trunk is used for the development of the most recent major release of wicket. In this case, that is wicket 2.0. When Wicket 2.0 is released, trunk will be used for the development of Wicket 2.1, etc. branches branches is used for the development of older major versions, when these are in active development. It is also used for bug fixing older releases. Currently you'll find the following directories there: branches/wicket-1.0.x- bug fixes for 1.0 (now unsupported) branches/wicket-1.1.x- bug fixes for 1.1 (now unsupported) branches/wicket-1.2.x- bug fixes for 1.2 (actively mainained) branches/wicket-1.x - development for newest minor version of wicket 1 (currently wicket 1.3). So if you are asked to check out wicket 1.3, then you'll have to check out branches/wicket-1.x. If you want the latest sources for Wicket 1.2, then you'll have to check out branches/wicket-1.2.x tags The tags directory is used for creating patches against a particular release. For instance, if you have a patch that you want to submit for wicket 1.2.2, then you'll have to create the patch against: tags/wicket-1.2.2 releases The releases directory contains all project files that were used for building a release, after creating the release. This means that the maven pom.xml files are changed to reflect the specific versions. So if you want to rebuild a particular release yourself, say 1.2.2 you can checkout releases/wicket-1.2.2. This will give you the exact sources that went into the release, including correctly dependent project files. Do not use these releases to create patches against, use tags/ for that! If you have questions, please don't hesitate to ask on ##wicket or here. Martijn -- Download Wicket 1.2.1 now!

Re: [Wicket-user] wicket:head in page template...
Igor Vaynberg wrote: afaik it should be ok, where does it say otherwise? Well, on the wiki it said today: " If you are authoring a page, you don't need (and shouldn't use) wicket:head tags but instead put it in the page's head section directly.". But Eelco edited the wiki page today, and modified it to: "The wicket:head pair can be used in Panels, Borders and Fragments, and is used for doing a 'header contribution', meaning that the contents will be written to the head section of the page the component is placed in. If you are authoring a normal page, you don't need wicket:head tags but instead put it in the page's head section directly. The exception to this is when you use markup inheritance, and one of the pages to extend wants to contribute to the header of some extending page, and the header is not part of the wicket:extend region. In that case, you can use wicket:head. " Problem solved! -Igor On 8/27/06, Erik Brakkee [EMAIL PROTECTED] wrote: Hi, In some of the documentation it is mentioned that wicket:head is not supposed to be used in pages (e.g. http://www.wicket-wiki.org.uk/wiki/index.php/Including_CSS_resources). However, if I use markup inheritance for all my pages, then the base markup will contain a head section. This head section could be insufficient since I might need some special css or _javascript_ for some pages. To do this, using wicket:head in those pages to include the extra content (e.g. style sheets or _javascript_) solves the problem. Therefore, I think wicket:head in pages is still useful. Is this a good use of wicket:head or should I use some other means to add specific content to the head section for some pages? Cheers Erik - Using Tomcat but need to do more?

Re: [Wicket-user] Fom validation
the problem with that is that once you added the form validator there is no way to remove it - so things like switching forms around that add their form validators will not work.also because you are doing it in onbeforerender() means you will be adding the form validator multiple times.
yes it sucks you have to subclass the form all the time - but you can create your own subclass of the form and always use that instead of wicket's form.-IgorOn 8/27/06,

Re: [Wicket-user] Dynamic Images
sounds like what you need is to stream the file to the output stream when the browser requests the image.easiest way to do this imho is the following (pseudocode)/** resource that can read a file given a name */
class FileResource extends Resource { private final String pathToFile; public FileResouce(String pathToFile) { this.pathToFile=pathToFile; } IResourceStream getResourceStream() { return
new IResouceStream() { int length() { return new File(pathToFile).size(); } InputStream getInputStream() { return new FileInputStream(pathToFile); } ...}so now you have a resource that can stream a file off disk - now to stream it just do
add(new Image(myimage, new FileResource(/tmp/myfile.gif)));not sure if it fits your usecase exactly - this is not for throw away images. if this is not what you need can you define your usecase better.
if it is what you need mind making a wiki page after you get it working? :)-Igor On 8/27/06, Brian Glynn

I've been pouring over the
documentation last few days trying to figure out how to use dynamically created
images in my application, with no luck.
Here's a little background: The
image is created by supplying a directory path, getWicketServlet().getServletContext().getRealPath(/tmp)
in this case, to the image creation method. The method then returns base
file name of the newly created image (example: foo123.png). I have
verified that the images are being created in the supplied directory, but
I'm not sure how or the preferred way of getting them in the application
I've tried adding the folder
location to the getResourceSettings().addResourceFolder(path)
and then passing the base name to the Image component. This
seems like the ideal solution, but by looking at the error page it seems that
the addResourceFolder() goes unnoticed and as the page only shows current class
package directory (/com/something/foo123.png) as been searched for the image.
I've also tried using a ResourceReference new Image(img, new
ResourceReference(path+name)), but it never seems to find the
right location of the image.
I am able to use the images by sub
classing DynamicImageResource and reading a File object of the image to a byte[]
in the getImageData() method, but that seems like overkill and clunky. There has
to be a way to just specify a url or path in the Image component, doesn't
there? I'm clearly missing something.
Thank you very much for your help,
Brian
