Wicket URL Encryption Key
On page 331 of Wicket In Action is the following excerpt, Note that you
should modify the default encryption key that is stored in
ISecuritySettings to prevent malicious hackers from using the default
publicly available key as an attack vector. Does this only pertain to
when Sun JCE is not available and Wicket defaults to no encryption? From
what I can gather, the key should be generated by...
KeyInSessionSunJceCryptFactory.java
if (key == null)
{
// generate new key
key = session.getId() + . + UUID.randomUUID().toString
();
session.setAttribute(keyAttr, key);
}

WicketFilter Config
Due to the fact that SpringWebApplication is deprecated, we evaluated several ways of configuring Wicket using WicketFilter. I found ContextParamWebApplicationFactory to work with a Spring Annotation approach. SpringWebApplicationFactory also works with a Spring Annotation approach, but since it returns a SpringWebApplication (deprecated) should it be avoided?

Encrypt Form Fields Using JS
Problem: Encrypt sensitive form fields (ie ssn) on client (javascript) Solution: Create behavior which fires javascript to hash field value and replace original value (###-##-) This sounds simple enough, but since the length of the hashed string will be considerably longer than the original string, validations on this field (ssn must be nine digits) will fail. I've considered placing the hashed value into a hidden field, but then the unencrypted value will be posted and the hashing accomplishes nothing. If I clear out the original value I lose server-side validations. Anyone have any ideas of the best way to accomplish this?

Re: Encrypt Form Fields Using JS
The only thing I've come up with to meet all the requirements is to set the hashed value to a hidden field, and replace the original value (123-45-6789) with all nines (999-99-). This would allow the validator to pass but puts a requirement on the js to validate the original value, ie it should not replace a 'Q' with a '9' Igor Vaynberg igor.vaynb...@gmail.com 08/02/2010 03:46 PM Please respond to users@wicket.apache.org To users@wicket.apache.org cc Subject Re: Encrypt Form Fields Using JS so how do you expect to validate on server side??? -igor On Mon, Aug 2, 2010 at 12:29 PM, mzem...@osc.state.ny.us wrote: Thanks for the reply, that would work however per our business rules the encryption must be one-way and will not be decrypted...

Re: Wicket adds jsessionid to redirect onto external page
On a related note...
The Wicket Strings class provides the method stripJSessionId...
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/util/string/Strings.html#stripJSessionId(java.lang.CharSequence)
And the Wicket SEO wiki provides a way to remove the JSessionId...
https://cwiki.apache.org/WICKET/seo-search-engine-optimization.html
@Override
protected WebResponse newWebResponse(final HttpServletResponse
servletResponse) {
return new BufferedWebResponse(servletResponse) {
@Override
public CharSequence encodeURL(final
CharSequence url) {
final String agent =
((WebRequest)RequestCycle.get
().getRequest()).getHttpServletRequest().getHeader(User-Agent);
return isAgent(agent) ?
url : super.encodeURL(url);
}
};
}
Would it be nicer to do something like this...
@Override
protected WebResponse newWebResponse(final HttpServletResponse
servletResponse) {
return new BufferedWebResponse(servletResponse) {
@Override
public CharSequence encodeURL(final
CharSequence url) {
final String agent =
((WebRequest) RequestCycle.get
().getRequest()).getHttpServletRequest().getHeader(User-Agent);
CharSequence encodedUrl =
super.encodeURL(url);
return isAgent(agent) ?
Strings.stripJSessionId(encodedUrl) : encodedUrl;
}
};
}
I understand why you would want to remove the jsessionid for bots, would
it be safe to remove the jsessionid for all users to pretty up the urls?
What are the implications of this and which method described above would
be preferred?

Hi Martin,
Yes, I've encountered this. I think it's a bug in WebResponse.
The culprit
is the line:
url = httpServletResponse.encodeRedirectURL(url);
The url should only be encoded when redirecting to the originating
site, but
the code doesn't check.
One workaround (short of fixing the bug) is to duplicate the
functionality
of WebResponse, commenting out the offending line. Then use it as
such:
getRequestCycle().setResponse(new
NonEncodingWebResponse((WebResponse)
getRequestCycle().getResponse()));
getRequestCycle().setRequestTarget(new
RedirectRequestTarget(url));
The source code is attached.

Hi!
I am doing something wrong? I am using:
getResponse().redirect(getParameterFromRequest(RETURN_PAGE));
But the URL contains jsessionid. I think this is wrong because the
target server does not understand the jsessiond and it returns 404
page not found.

As a side effect you will disable session for cookieless connections. Wouldn't this be desired, ie bots...

public void onClick(AjaxRequestTarget target) {
panel.setOutputMarkupPlaceholderTag(true);
target.addComponent(panel);
panel.add(new UploadFilePanel(filePanel));

i understand that i didnt declare the things in the markup, but thats
what i want (create them not at the start, but never or later, when the

thanks for help
1-Put
uploadPanel2.setOutputMarkupId(true);
uploadPanel2.setOutputMarkupPlaceholderTag(true);
uploadPanel2.setVisible(false);
when you create the panel.
2- on
public void onClick(AjaxRequestTarget target) {
uploadPanel2.setVisible(true);
target.addComponent(uploadPanel2);

Subject:Re: Feedback messages with parameter substitution
Folks,
I found the solution from the thread Using getString with
parameters
http://apache-wicket.1842946.n4.nabble.com/Usage-of-getString-with-parameters-model-td1875254.html
.
And this is what I did in the properties file..
premessage.fileAlreadyUploaded=The file ${0} is already uploaded/pre
(Note the $ sign)
And in the java code..
error(getString(message.fileAlreadyUploaded, new Model(new
String[]{fileUpload.getClientFileName()})));
It worked like a charm.

Dear friends,
Please forgive me if this question is asked before and answered. I
seriously searched for this in the mailing list and other areas and
couldn't
find any solution.
I've seen great examples of using StringResourceModel for parameter
substitution in components like Label.
But what I want is to display a feedback message, say an error message
with
some dynamic values in it. Something like The file abc.txt is already
uploaded, where abc.txt shall be dynamic.
So the localized text in the properties file would be something like
message.fileAlreadyUploaded=The file {0} is already uploaded.
I've tried using something like this...
code
error(getString(message.fileAlreadyUploaded, new Model(new
String[]{fileUpload.getClientFileName()})));
/code
but that' doesn't work..I also tried using StringResourceModel but to no
avail.
I know I'm doing something wrong, please guide me to solve this problem.

Re: Using Wicket with businness model classes that check for rules
Ok but if the conversion has to be done multiple times why not encapsulate
it and clean up your code, rather than coding a conversion for each dto
every time its needed. With my suggestion the frontend calls a service to
do the conversion, then supplies the primed object to the service to
persist it. I somewhat agree the service perhaps should not need to know
about the frontend's model to do its task.
Never the less its probably a matter of taste...
Back to the original question...what if you extract your business object
validation out into a service. Then your business objects can call that
service to validate, and you can write custom validators for wicket that
call the same validation service. This would prevent you from having to
write validations twice in both the business layer and frontend and gives
you the ability to attach an error at the component level, no?

I don't know that I would agree that the conversion logic needs to be
taken out of the front end. The front end is where the data is
collected. It may have to be collected in a specific way
(FileUploadField perhaps) that is connected with the chosen
presentation layer (Wicket in our case). It is the UI's
responsibility to translate the input it receives from its user(s) and
transform it into a format that the business model requires. That's
my $0.02

Re: Just 100K per session? That would be my dream come true! (Anyone here who has tuned session size before?)

Hi Johan and Igor, well, on one hand I am using App Engine, and puts are limited to 1MB. Even with pagination and limitation of each page to 50 users (totalling 200Kb in memory for the whole page), I had to limit the pagemap size severely to ensure I am always below 1M. In Wicket 1.5 it's a lot easier to write an adaptive EvictionStrategy to control memory usage, so I can be more flexible and evict large pages more aggressively than smaller ones. Still, displaying say 500 users at once will still not be possible if each user-row can take as much as 5K. But I am not complaining. I knew that App Engine has this limitation, and I make my own product specifications, so I can live with it. On the plus side, App Engine (due to its restrictions) scales really well, and I am not worried if some day thousands of users will use my app concurrently. But although a typical server may have many Gigs these days, you'd still be in trouble if thousands of users came slurping 40M each, that's why I do think that session size remains an important consideration. I would strongly recommend anyone not to leave optimisation till the very last, but plan ahead and spike some of the most complex screens first, since Wicket *is* different in that respect. Sorry to hear I can't optimise easily, but thanks for the quick responses Johan and Igor! Your support on this forum is truly legendary! Will try to figure out the autoAdd() soon :-) Per but if you have it down to 200K then 50 users it is nothing... thats 10MB on memory If if both where 2X so 400K and 100 users thats still only 40MB in memory Thats for a server nothing..

Despite LDMs, CompoundPropertyModels, and no, there are no domain objects in there, and no finals. What on earth am I doing wrong? My goal is to display a long list of, say, users. Each users should list a few labels (name, position, location, etc) and images to show who's an admin/poweruser. Each user has a profile picture. Each user who is also a manager should have image icons of their subordinates' profile pictures (e.g. a nested ListView) And I want 5 or 6 AJAX labels so I can quickly lock/unlock users, delete them, give and revoke certain rights. Despite lots of profiling each row is still 4K to 6K. This adds up for even just 50 users. Can this be reduced, at all? I mean, it seems that 56 Bytes is the minimum for a Label, 32 for a PropertyModel, 80 for a ListItem, and some 200 for an AjaxLink. 400 for an Image (or alternatively 272 for a label with 2 AttributeAppenders to also render an image), and unless the whole list disappears from the page's object graph, all those small numbers DO add up. My final hope was the RefreshingList, but no, it also keeps the list items stored in the page. What I really would like is a list that does not maintain all its items, but throws them away, just like a LDM throws away the domain object, and just reloads when needed.

little misleading. Some ways to think about it differently...
id is synonymous with a small sub-set of the entire result-set which
can be used to rehydrate the detached model
The model is the data you want to provide to a repeater for instance, so
this can be a single Contact model (one query for each row) or a
ContactList (one query per page with pagination). Retrieving a list
instead of each contact individually would be more efficient.

If I understand where you are going I completely agree the example is a
little misleading. Some ways to think about it differently...
id is synonymous with a small sub-set of the entire result-set which
can be used to rehydrate the detached model
The model is the data you want to provide to a repeater for instance, so
this can be a single Contact model (one query for each row) or a
ContactList (one query per page with pagination). Retrieving a list
instead of each contact individually would be more efficient.
If you need an example let me know...

First render thanks for your replies.
@vov: If i use this:
public IModelEntity model(Entity entity)
{
return new ModelEntity(entity);
}
In this case the memory footprint of the session grows because you return
Model object that is not a transient object(or this is what I've read in
wicket documentation...!!) . ¿This means that if you dataview have 100
rows
you have 100 ModelEntity stored in your session?

Re: Perfomance of IDataProvider
super(l) stores the model as an instance variable on the superclass. When
getObject() is called on the LDM, it checks to see if the instance
variable (the model object) is null. If it is null, load() will be called
to populate the model. Once the request is complete the model is detached
(instance variable set to null). Then the cycle repeats...
A use case for super(l) is SortableDataProvider (SDP) seen below and taken
from Wicket repeaters example. The SDP retrieves the records of interest
for pagination using iterator(), then creates a model. If the object was
not passed into the DetachableContactModel, the load() method would make
another db call to populate the model.
public class SortableContactDataProvider extends SortableDataProviderContact
{
public SortableContactDataProvider() {
// set default sort
setSort(firstName, SortOrder.ASCENDING);
}
public IteratorContact iterator(int first, int count) {
return service.find(first, count, getSort()).iterator();
}
public int size() {
return service.getCount();
}
public IModelContact model(Contact object) {
return new DetachableContactModel(object);
}
}

It is referenced by the superclass (LoadableDetachableModel in this
case). It will cache the list until after the request cycle is
complete. Upon subsequent request cycles, the load() method will be
called to re-load the list.

In this example , the object that you're wrap in the inner model (List
l
that you are send in super() constructor) is not used anywhere... ¿i'm
wrong? in this case , ¿why should be using this (in reference a List l
in
constructor)?

RE: mountSharedResource() on huge amount of images
For that many photos I would suggest storing them in a database. Storing
that many images on the file system is cumbersome and inefficient in my
opinion. You might run into many headaches especially around backups,
deploys, upgrades, performance, file names, storage space, etc...

Re: mountSharedResource() on huge amount of images
No offense Bas but that seems like a major hassle, especially considering
with an ORM its a simple update/delete/find. When it comes time to build
out new servers now you have to shuffle around 300k photos instead of
simply replicating a database. Also sounds like it would make debugging
more difficult when your images are three or more folders deep. And what
if you want to store attributes along with the photos? Like say user
comments, or flag them for inappropriate content, copyright infringement,
etc. What if there is an open file handle when you try to delete the
image? Just seems to me a much smoother solution to put in a db. But
with that I'm bowing out because as you said it's a heated debate and
comes down to personal preference.

Subject:Re: mountSharedResource() on huge amount of images
Now you're talking about rendering them, which is a different topic than
mounting a resource which serves said images.
You'll only need to mount a single shared resource which serves all the
images. However, given the amount of images you can consider allowing
your front-end (e.g. apache httd) or a dedicated webserver serve the
images.
Since you mention that the amount of images can be potentially large
(250), I'd suggest removing the show all option, or using an ajax
viewport (max 20-50 images on-screen at a time, when the user scrolls
you load new images over ajax).
Someone else just suggested storing images in the database. While there
is usually heated debate about this topic (files on disk vs in the
database), let me just say that simply having lots of images is no
reason to move images into the database. For starters, you can always
store your files in a hashed folder structure, e.g. when the ID is 1234,
store the image in a file/folder called /1/2/3/4.jpg

Re: PackageResourceReference, MetaInfStaticResourceReference and timestamps
Hi, I made a new test (serving a png and a js) with current trunk and the gap is much smaller now: tomcat is 25% faster on average. Attila Attila can you elaborate on your tests? Are you comparing the difference between using a resource reference (js) and image component (png) in wicket vs linking straight the to the files in html? If so, what relevance does whether the static files are in META-INF or WEB-INF have? Not that much because if I am correct the extra overhead is introduced by having wicket process the resource and spit out the markup...

Re: model help
Not sure what your objects look like but I will try to answer question

Not sure if this will work for you...sometimes I find myself using
PropertyModels mixed with CPMs...
new ListView(myId, new PropertyModel(foo, widgets))
And it may not be entirely obvious you can use dot notation to access
nested objects...new PropertyModel(foo, bar.name) for the following;
class Foo() {
private Bar bar;

Subject:model help
1. first I'd like to ask if there is any good reading material out there
regarding models. In particular I want to figure out all the nifty things
you can do with them via nesting/chaining etc. I've read Wicket in Action
..
but it seemed to gloss over the advanced stuff you can do with them .. and
I've read the docs.. and just from reading those, well it's not obvious
what
you can do with them and why...
2. I have a specific problem and I'm looking for some hints. I have a foo
bean that I get from a DAO layer. The foo bean has the usual name,
description String properties. It also has an array of 'widget' beans
called
'widgets'. The widget beans also have a name and description properties
ans
well as various others.
So I have a form and I map the foo.name, foo.description properties to
TextField components using a compundpropertymodel. The 3rd component is a
ListView, which I want to use to display the widgets.
First problem I run into is that the ListView model needs to be a List,
not
an array of Widget. So the compoundpropertymodel barfs at this point. I
don't have any control over the beans and I'd rather not wrap them .. I
want
to bind the components directly to the bean properties.
I'm wondering if there is a neat trick I can use involving model nesting
or
something like that to solve this problem? Or maybe there is a way to tell
the CPM that for property 'widgets' .. do something different.. like
array-to-List conversion ..
I'm a wicket newbie and the model-penny hasn't quite dropped yet.. so any
help would be most appreciated.
TIA

Re: flexible authentication
I think you could do it by using a base role that all users receive,
then add additional roles to tighten it down. You would then need to fake
authentication of the base users by calling session.authenticate(user,
pass) and assigning the BASE role, even though the user won't
explicitly log in. Users who do log in will receive the correct role such
as ADMIN
Some users secure (ADMIN), some users wide-open (BASE)
@AuthorizeInstantiation({ADMIN, BASE})
All users secure
@AuthorizeInstantiation(ADMIN)
You might also consider subclassing the page and marking that with the
annotation, then handle the response to the secured or unsecured version
by checking if the user is signed in. I'm not sure where you are going
with this because I'm not sure why you have the requirement of being
secure for some users but not secure for others.

Subject:flexible authentication
Hi all,
my web application is using the wicket authentication approach
(AuthenticatedWebSession) and all my secure java files are marked with
@AuthorizeInstantiation(ADMIN)
So once I added this annotation there is no chance to bypass the
authentication.
But what if there is the need to be flixible? What if for some users the
page A should be secure and for others don't?
Let's assume there is is page with e.g. contact informations and a user
can
decide for his own if the page should be accessible with or without
authentication. How can I achieve that without using the wicket approach?
At
the moment it don't think that the wicket approach is the right one?!
Thanks in advance.

Re: [VOTE] Behavior of CheckBox With Respect to setRequired(true)
I second Daniel's comments. +1 for option 1 From: Daniel Neugebauer mailingli...@energiequant.de To: users@wicket.apache.org Date: 04/01/2011 02:56 PM Subject:Re: [VOTE] Behavior of CheckBox With Respect to setRequired(true) I would stick with 1 (required to be checked). The main reason would be not to break compatibility with old versions. I actually used .setRequired(true) on legal checkboxes (disclaimers) in one of our applications because if I have a required checkbox I expect it to be needed to be checked. Although I will change that in our project now that I know such a change is being discussed, I wouldn't expect others to be that observant of the issue and have unit tests that prevent anything from breaking on a future upgrade. BTW an empty string (that's not null) is a string nevertheless. Following the argument that an unchecked (false) checkbox should be regarded as valid if it is required, an empty string should be accepted as a valid input as well. I've just tested it with Wicket 1.4 and actually both of the following TextFields validate to a failed state: TextField tf1 = new TextField(text1, new PropertyModelString(this, test1)); tf1.setRequired(true); tf1.setConvertEmptyInputStringToNull(false); form.add(tf1); TextField tf2 = new TextField(text2, new PropertyModelString(this, test2)); tf2.setRequired(true); tf2.setConvertEmptyInputStringToNull(true); form.add(tf2); So, TextField.setRequired doesn't validate the syntactic meaning as well, instead it validates the semantic meaning, just as CheckBox.setRequired does. If that's consistently used throughout Wicket, I would expect CheckBox.setRequired to validate false unless the CheckBox is actually checked.

UploadProgressBar Possible Bug
Sorry but I do not have the time/resources to create a quickstart (I don't use Maven) but I wanted to alert the group to an issue I had in case anyone wanted to test/fix it.

There also seems to be some difference between Wicket 1.4.16 and 1.4.15. Using 1.4.15 the progress bar disappeared but the page continued to refresh repeatedly.
