setResponsePage in AjaxSubmitLink causing AjaxError
I'm using Wicket 6.6.0, in an AjaxSubmitLink when I do a setResponsepage(myclass.class) or (throw new RedirectResponse) i get the following error in the wicket ajax debug console: *ERROR: * Wicket.Ajax.Call.failure: Error while parsing response: Error: Invalid XML: !DOCTYPE html The error console also includes the full HTML of the destination page. Any idea whats going on here? -- Jeremy Levy
Re: setResponsePage in AjaxSubmitLink causing AjaxError
I figured it out- further up in the code I was calling: new PageReference(new PageProvider(MyPage.class).getInstance().getPageId()) which was causing the problem.

Re: HttpsMapper broken with Mounted pages
Just to close the loop here. If setRootRequestMapper(new HttpsMapper... is done before you add your mounts, they will not be enabled for SSL. I've added and updated the Wiki to reflect this as well as requested the line in the javadoc where this is be mentioned be made more prominent.

Terracotta Sessions and Wicket
We've been using Terracotta Sessions with Wicket successfully for some time now with a fairly onerous side effect. The DiskPageStore temporary directory grows steadily and never gets cleaned up, eventually leading to us having to manually go and clean up the directory. The issue appears to be that if a session fails over to the other node it maintains the sessionid from the other server (as expected) however, because we use sticky sessions via the jvmRoute in tomcat a session ID looks like 2uWDurCx3V07Oe8LBn0V.node1 even if its currently on node2. Therefore when the unbind/cleanup method of DiskPageStore/SessionEntry attempts to clean it up it doesn't find anything and leaves the orphaned session on the node where the session originated. I was thinking that a easy fix for this would be to extend the DiskPageStore and have it ignore the jvmRoute when serializing the session. Does this sound like a good idea? Thanks. Jeremy -- Jeremy Levy
Re: Terracotta Sessions and Wicket
Actually, after thinking about this some more, it has nothing to do with the jvmRoute on the session per se, it's because the node from which the session originated never has the unbind/method called for that session.

Re: Configure http and https with apache and jboss
Thats correct, your entire HTTPS set up can be only from Apache outwards and
AJP/HTTP between Apache and JBoss/Tomcat.

Re: POST path via Ajax erratically invalid when used with #
Thanks for the reply, as I already mentioned I've tried running this in the
debugger in Chrome but it's not clear to me where the HOST part of the URL
is being generated all I see is the path.
The full URL that is getting posted to is:
http://mobile/MyPagescreen-two?x=1cBpJXjtIYZljhKs29abIqj8*YDCtKbjg*TV2waFYQRLE*9vNYy87LLwY1SctZ0Ck8iPyZttk0qfiInaa9kSd98b1moKXZbN-yjDEBXqdDnU4WkRPLW5AArandom=0.7044208080042154http://mobile/webkitregscreen-two?x=1cBpJXjtIYZljhKs29abIqj8*YDCtKbjg*TV2waFYQRLE*9vNYy87LLwY1SctZ0Ck8iPyZttk0qfiInaa9kSd98b1moKXZbN-yjDEBXqdDnU4WkRPLW5AArandom=0.7044208080042154
The mount is actually just /MyPage 'screen-two' is the value after the #,
the URL in the browser looks like http://mobile/MyPage#screen-two.
As you suggested I also tried
debugging
org.apache.wicket.ajax.AjaxEventBehavior.generateCallbackScript(CharSequence),
but from what I can tell that generates the relative URL to POST to.
Ex: var
wcall=wicketAjaxPost('?x=3NGhze8Hqqc*UOnOuxCljvnljwk0iN2tSqud8EMVbEweya7HhUn*6fgOmnCv6OwW',
wicketSerialize(Wicket.$('username101')),function() {
}.bind(this),function() { }.bind(this), function() {return
Wicket.$('username101') != null;}.bind(this));
From debugging the javascript, best I can follow is that the actual POST is
made at line 938: t.send(body);
However, looking at all the objects until that point still only describes
the url as ?x=
3NGhze8Hqqc*UOnOuxCljvnljwk0iN2tSqud8EMVbEweya7HhUn*6fgOmnCv6OwW.
What's interesting is that clearing the session seems to fix the problem
until I try it a second time. It's also worthwhile to note that if I load
the page and include '/' at the end of the URL it works perfectly,
repeatedly.
It's still not clear to me where the http://xxx/xxx or BaseURL comes from in
the wicket JS, is that a function of XMLHttpRequest? location.href
references the correct Host..
Any ideas or insights?

Re: AjaxButton and HTML5 fields
Thanks Martin, that worked beautifully, well perhaps not beautifully but

Hi Jeremy,
Yes, this is the way to make it working.
In Wicket 1.5 all this is already improved and Wicket provides Number,
Url and Range TextFields out of the box but it is quite easy to use
the other types too.
To make it work in 1.4.x you'll need to use the monkey-patch approach.
You can see the history of
https://github.com/wicketstuff/core/tree/master/jdk-1.6-parent/wicket-html5-parent/wicket-html5
.
There is a Behavior which did exactly this before the improvements in
Wicket 1.5.

DiskPageStore with Terracotta
When using Terracotta WebSessions 3.3.0 with Wicket 1.4.9 on JBoss 4.2 / Tomcat6 the DiskPageStore grows infinitely. After a few days our jboss/server/myserver/work/jboss.web/localhost/[context]/[filtername]-filestore is filled with gigabytes of data. The terracotta folks say that they aren't doing anything specifically with the pagestore. I was hoping some of the wicket folks had an idea. How does cleanup normally work, and any ideas on how I should debug it? Should I try setting an explicit limit on the disk page store size? JL

Thread.dumpStack();
}
StackTraceElement[] out = e.getStackTrace();
StringBuffer sb = new StringBuffer();
for (StackTraceElement ex : out) {

if (out.length == 0) {
log.error(The exception had a length of 0, dumping Stack);

What I have seen so far is that e.getStackTrace() has a length of 0, so I
added the thread dump...

In my own RequestCycle I've done the following:
@Override

super.logRuntimeException(e);
log.error(e);
}
Which doesn't help because I'm just doing the same thing twice:

I tried e.printStackTrace(); but log4j SMTPAppender takes each line of the
stacktrace and emails it which generates way to much volume. Any
suggestions?

I have seen other things cause this however, if you are using jvmRoute with a node that is down and your don't properly fail over you will consistently get this error.

I had a problem with session ids changing when trying to swtich between secure/insecure pages. If your first request to a tomcat server is secure, and a session is created, tomcat will create a secure session id cookie that will only be sent in https requests. If you request a non-secure (http) page request it will not send the cookie, and a new insecure session cookie is created. One way to fix* this is to use a http request filter that checks for new session id cookie creation, and writing a new insecure cookie if a secure one has been created. Something like this: http://forum.springsource.org/archive/index.php/t-65651.html *when I say fix, I mean make the system less secure :) Igor Vaynberg wrote: yes, a changing sessionid will cause a page expired error because the client all of a sudden gets a new blank session. changing session ids can be caused by either session expiration or a manual session invalidation - like during a logout procedure. you have to figure out what causes the session to get dumped and a new one to be created in your application/servlet container. -igor On Thu, Jun 11, 2009 at 9:56 AM, Dane Laverty danelave...@gmail.com wrote: I'm trying to track down the source of frequent PageExpiredExceptions that we're getting on our deployment server.

Re: Some SignInPanel Questions
1) No valuemap is a cheap model, the only value is using it in this cause is
that it's quick to write, see models for more information.
2) That example is designed to show you how to do sign in, not necessary the
best way to handle getting data from forms. From looking at the code you
highlight I'd say it's duplicative.

I don't know if these are actually SignInPanel (from wicket-auth-roles)
questions or if they're in fact more general wicket questions; probably
the latter, but the SignInPanel class is where I noticed these things.
1) In the SignInPanel I notice that instead of having a couple of private
String variables to represent the username and password, a ValueMap is used
instead. I'm curious as to why. Is there some benefit to using a ValueMap?
2) When the values that are typed in the username and password fields are
needed to pass to the signIn() method, they are retrieved in ways that I
would not have normally considered. The username value is retrieved with
the
getDefaultModelObjectAsString() method of the username's TextField
component
and the password is retrieved with the getInput() method of the password's
PasswordTextField component. Why are the values retrieved this way? I
assume
there's a good reason, but because I don't understand it, I'm a bit unsure
as to where in my own application I should be using the same techniques.
My first instinct for a panel like this would have been to add two String
variables to the class to act as the model for the username and password
TextFields and then to access those values with normal getter methods. I'd
would find it quite instructive to know why these other approaches were
used
instead so that I can take similar actions in my own application.
Thanks!
I'll include some snippets from the SignInPanel class below so that it
doesn't have to be looked up:
-
private final ValueMap properties = new ValueMap();
-
add(username = new TextFieldString(username, new
PropertyModelString(properties,
username)));
add(password = new PasswordTextField(password, new
PropertyModelString(properties,
password)));
-
public String getPassword()
{
return password.getInput();
}
-
public String getUsername()
{
return username.getDefaultModelObjectAsString();
}

Hi!
Just wondering how this works, precisely, since I've been having some
intermittent problems.
I have a link that has an onClick() method that looks something like
this (in principle):
public void onClick()
{
String token = checkForToken();
if( token == null )
// Do something that will cause token to be non-null next time
throw new RestartResponseAtInterceptPageException( SomePage.class );
doSomething( token );
}
During the process of doSomething(), I make the call to
continueToOriginalDestination. This returns to the URL that includes the
ITargetListener, so my expectation is that the onClick() above will be
called again. Since this time checkForToken() returns the token, I can
continue processing normally.
This is working intermittently for me, so I believe that the way I
_think_ things work is correct, but it would be really nice for somebody
to confirm this for me.
Thank you!

Problem with WebRequestCodingStrategy's and mobile phones
We figured out something very interesting with the default URL coding strategy's that Wicket uses when using mobile phones / devices. We run a fairly heavily trafficked mobile site, and having been using CryptedUrlWebRequestCodingStrategy for sometime. While attempting to debug some page timeout issues we switched to UrlCompressingWebCodingStrategy and we started getting compaints from users that they were getting HTTP error 400's. We were able to repeat the error locally, it happened only when using some specific phones and mobile browsers. Specifically on the Motorola V3 (useragent: MOT-V3re/0E.40.29R MIB/2.2.1 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Link/6.3.1.20.06.3.1.20.0) and other UP.Link browser moble phones. We noticed that when the user got the 400 error there was nothing in our tomcat logs, or even in our apache logs. Switching to standard WebRequestCodingStrategy had the same issue. I suspect that there are some characters in the form submit url ( :'s ?) that this crappy browser can't figure out to post to. Swiching back to CryptedUrlWebRequestCodingStrategy fixed the problem. We tested this on several other handsets that we have available and can confirm that it breaks all form submits. This is a some what obsecure case, and perhaps irrelvant if you don't run a mobile site, but we saw our number's drop by about 20% - 50% until we figured this out. Hope this helps someone else.

When searching for the term acct, the form redirects to a BookmarkablePage with a URL that looks like: http://jetty-host:port/app/FindTagByName/tagname/acct/ and on that page there are Javascript and CSS elements with SRC and HREF attributes like this: ../../../css/standard.css Links in the PagingNavigator point to pages like this: http://jetty-host:port/app/?wicket:interface=:6:1::: and the SRC/HREF attributes here look like this: css/standard.css Which works fine.

Another approach to solving this is to block all the stateful pages in my

no, you are not missing anything. you see, when you go stateless, like
what you want, then you have to recreate all the magic stuff that
makes stateful links Just Work. Without state you are back to the
servlet/mvc programming model: you have to encode the state that you
want into the link, then on the trip back decode it, recreate
something from it, and then apply that something onto the components.
This is the crapwork that wicket does for you usually.

no, you are not missing anything. you see, when you go stateless, like

servlet/mvc programming model: you have to encode the state that you
want into the link, then on the trip back decode it, recreate
something from it, and then apply that something onto the components.
This is the crapwork that wicket does for you usually.

What I think is happening is this: 1) Wicket says: redirect to /web/ 2) Tocmat makes the url absolute by prepending the virtual host. Since you have ProxyPreserveHost on, tomcat sees the virtual host as localhost and NOT localhost:8080, and returns http://localhost/web/xxx as the new lcoation. 3) Apache mod_proxy does NOT reverse proxy the url, because it does not have the :8080 on it and does not match your rule. If you remove the ProxyPreserveHost on, tomcat will return http://localhost:8080/web/x as the redirect location and Apache will reverse proxy it. The only downside of this is that your wicket app will not know the REAL virtual host, and so automatically generated absolute URL's (for example in emails) will be wrong.

Re: After 1 minute the Pagemap null is still locked
Thanks Igor / Martijn for your help. As you mentioned Wicket had nothing to do with it. I had a piece of code that was executed when a user clicked a certain link and was blocking by accident, caught in a loop peging the CPU. Your suggestions of kill -3 to get the thread dump over a couple of samples helped me to narrow down the issue and fix it. Thanks very much.

Overtime the CPU usage progressively gets more and more backed up (I assume because this issue keeps happening and compounds the load). The longest page request on the site is a panel which has 4 child lazy loading panels but none of them take longer then a max of 4 seconds, which is pretty strictly enforced. The CPU getting pegged is a huge problem because it is forcing us to restart the server every some often.

We have been thinking about this a little bit as well... It broke down into two parts: Making FaceBook Wicket components that represent and render the corresponding FBML.

Re: DropDownChoice with -1 value
If you create a properties file for the page class and use dot notation
matching your page hierarchy but leave the last value as null you can set
the default value:
For example:
theForm.birthdayMonth.null=M
theForm.birthdayYear.null=Y
theForm.birthdayDay.null=D

Hello Everybody
I'm using wicket.markup.html.form.DropDownChoice and it
works fine until now, when I got a suspicious behavior (maybe bug)
Into database I have one data called TEMP CUSTOMER that has
id = -1 (it's business logic of our client, that data came through
database importation, and I can not update that data)
Following my code:
List relations = relationManager.list();
final DropDownChoice ddRelations = new DropDownChoice(relation, (
task.getRelation() == null) ? new Model() : new Model(task.getRelation()),
relations, new IChoiceRenderer() {
public Object getDisplayValue(Object object) {
return ((Relation) object).getName();
}
public String getIdValue(Object object, int index) {
return String.valueOf(((Relation) object).getId());
}
});
form.add(ddRelations);
and HERE is the source code generate on html :
select name=relation
option selected=selected value=Choose one/option
option selected=selected value=-1TEMP CUSTOMER/option
option value=1CUSTOMER 1/option
option value=2CUSTOMER 2/option .. and so on ...
As you can see, there are two options with selected attribute,
therefore always TEMP CUSTOMER will be selected.
When I saw this, I though why in all other dropdownchoices
that I had already implemented following the same sample are working very
well ?
I had no doubts, and I changed the TEMP CUSTOMER id
on database to 1 and ... sup.. the dropdownchoice works fine.
But I can't change that data, so I rollback, and also the
problem rollback.
I ask to you , experts guys, if I put a negative value into a
dropdownchoice, it will be the default value if none is selected ?
How I can do Choose one be the default value in this specific case ?
Any idea to solve this problem ?
Thank you

So you can do a dictionary attack on MD5 hashes or brute force on short plaintexts if you don't use a salt. Weeha. So what else is new? This has ABSOLUTELY NOTHING to do with MD5. This works with SHA1, and ANY other hash. That's why you use salts. When you store a hashed password in the database you generally do something like this. Take a random generated alphanumeric string of 10 chars: GXSYvmzz0y Then take the plaintext password, i.e., test123 and append it to the salt: GXSYvmzz0y$test123 Now make an MD5 hash: ca62c4bd0a5094d9198112a6ce6ab4f4 Now prepend the salt to the hash, and store this in the database. In other words, store this: GXSYvmzz0y$ca62c4bd0a5094d9198112a6ce6ab4f4 in the database. To verify the password for a user, split the stored value, use the salt to compute the required hash, and compare. Good luck cracking that.

For example, the 36GB md5 table allows you to find which string of 1-8 characters from the lowercase alphanum charset was used to generate a specific has. To be specific, if I provided the hash: 4a251a2ef9bbf4ccc35f97aba2c9cbda rainbow crack would find the key: test123. However, if I provided the hash: 36a03a8a4c00e81f03d62d8b04bbbf4d rainbow crack would *NOT* find the key: Test123, since it contains a character not in their character set. Furthermore, it would find no key at all if it so happens (which is overwhelmingly probably the case) that there exists no 1-8 string lowercase alphanum string which has this hash. with classic rainbow tables or hybrid rainbow tables you get a 99,9% chance to score a hit for under 1h time... sounds not very secure to me Only for specific plaintexts, after precomputing the tables. Nope, MD5 password hashes are still perfectly fine. sure? Yes, secure enough. In practical use, passwords are rather weak, and there are many easy attack points (social engineering, reading passwords from an unprotected password vault of the browser, dictionary attacks, etc.). Hashing the password is (in general) used to hide the plaintext from view (in a DB for example). Furthermore, anybody can gain access to an account if they have write access to the DB by simply putting in their own hash. Hashing the password client side is actually UNSAFE. This means the hash goes over the network, and somebody else can just send the same hash to the server to log in without ever knowing the user's password. and its more save if the md5 sits in the RDBMS that may be breached? Yes again. If your RDBMS is breached you've got far more serious issues. Futhermore, somebody sniffing a hash going of the network (especially LAN) is *EASY*. If you have a secure setup with your RDBS, it's on a safe network, behind a DMZ, and not accessible from the internet directly. Apart from other confidential data that will be leaked (e.g. credit card numbers, or whatever), I think hashed MD5 passwords are the least of your problems. But I agree with one thing: since it's free in Java to use SHA instead of MD5 (all you have to do is change 1 little string), you may as well use SHA. Regards, Sebastiaan

possible bug in 1.2.6 / 1.3 Include
I found this while working on 1.2.6 and checked it out in 1.3 and it's the
same. It appears as though Include does not pay attention to the contextpath
if it is explicitly set.
Line 162 (In 1.2.6) or line 233 (in 1.3b4) of Include is the following line
which as I understands it builds a absolute URL from a relative path from
the model:
buildUrl.append(req.getContextPath()).append('/').append(url);
It's using the request's context path to build the absolute URL, if this is
behind a proxy it will fail, I changed my copy to this:
buildUrl.append
(getApplication().getApplicationSettings().getContextPath()).append('/').append(url);
Am I misunderstanding this?

Using mod_proxy / mod_rewrite to hang app off root
I've having trouble getting my application behind apache hanging off the root, my application servers url are as follows: http://localhost:8080/context/servlet/bookmarkpage I'd like the URL to be: http://localhost/bookmarkpage I've set up Apache 2.2 in from of it. I can get Apache2 working so that the url is http://localhost/servlet/bookmarkpage, however I want to get rid of the servlet as well. To do that I am aware of two options, one is to write a rewrite rule which removes the servlet from the url and exclude any resources from the rule. I can't quite figure that rule out but I am sure I can given some time. The other option is to set the wicket servlet to /* which is simple and works very nicely, however then ajax calls backs fail. Is there a way to fix that? Perhaps a rewrite rule? What are other people doing? j
Custom Content
I'm attempting to load the markup for a page based on values that are available when the page is constructed. For example, I want to be able to pass a parameter into a page and then lookup the name of the content file in my database based on this parameter and then have the page load and display the appropriate content. I've tried looking at the custom resource loading example in the examples package but that seems to work by loading content based on the class name and I didn't see a way to extend it. I've tried overwriting the newMarkupResourceStream method, but it seems to be called before the constructor is called as well as before the session is available. Any suggestions? j
Re: Custom Content
Will that work if the content includes a form? I would like to be able to have a page which includes a form but have a couple of different versions of the HTML and be able to select the one I want based on the param... In otherwords the HTML will contain form elements with wicket:id attributes which I want to be associated with elements I've added in the form class.

Re: Custom Content
Igor, I was afraid you were going to say that, we are still on 1.2.5 and I think those are 1.3 features :(. We aren't planning to upgrade until it's released. Can you think of any alternatives? I've divided the entry page and the form page into two separate pages, the first page figures out which html file to use, stores it in a static hastable somewhere else, using the sessionid as the key and forwards to the page that loads the HTML file. ( I know thats very unwickety, not to mention hacky). I then load the value out of the hashtable in newMarkupResourceStream and that works. Only issue is that newMarkupResourceStream is only called on the first time the page loads when it's compiled with the HTML i suppose. Is there any way to prevent that for one class / page?
