Can I HTTP Post from static html page to a Wicket page?
Hi all, I want to post to a Bookmarkable page from a static (non-Wicket page). I am having a tough time figuring out exactly how this can be done. For example, I simply want a static home page to contain a basic form with the form action=/auth/login . Is this possible with a Wicket page? I can't find any examples for pure http posts to a wicket page/form. thanks chris -- View this message in context: http://www.nabble.com/Can-I-HTTP-Post-from-static-html-page-to-a-Wicket-page--tf4289562.html#a12211582 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
A Relative path question
Hi all, I have a non-Wicket domain lets say, www.mydomain.com . This domain passes requests to the Wicket filter via mod_jk to this path: www.mydomain.com/myapp . The home page on www.mydomain.com is completely static except for a wicket form that is dyamically written via a Java script document write (i.e. script src=/myapp?wicket:bookmarkablePage=:com.mysite.LoginFormSnippet.). We dont want the entire domain of www.mydomain.com to be Wicketized, hence the small snipppet writen via the script tag. The problem is everything wicket related is written from the relative path (i.e. / ) not with the /myapp prefixed in front. Therefore, the component, Wicket Javascript references, etc are broke because of the relative path. What can I possibly do to over come this? I have received nothing but great responses from this forum, hopefully I can get one here because I really dont want to mount the entire app at the root of the domain in Apache for various reasons :) thanks in advance. chris -- View this message in context: http://www.nabble.com/A-Relative-path-question-tf4303862.html#a12250696 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: A Relative path question
Ok, I think may see the start of my problem. I have been unable to setup a WicketFilter with JkMount /myapp* . I have only been able to successfully use the WicketWilter if my JkMount is JkMount /* default for example. I have been trying exactly what you mention below but to no success (sorry for the confusion): -- Run a Wicket webapp on http://appserver.com:8080/ --(Note that's a root context path.) -- - Map Wicket to the root using servlet mapping/filter mapping of /*. -- - Pass requests from an Apache which land on www.mydomain.com through --to the Apache, unless they land on /myapp/*, in which case send them --to Wicket. Here is my filter: filter filter-nameMyWebsite/filter-name filter-classorg.apache.wicket.protocol.http.WicketFilter/filter-class init-param param-nameapplicationClassName/param-name param-valuecom.mywebsite.MyApplication/param-value /init-param init-param param-namefilterMappingUrlPattern/param-name param-value/*/param-value /init-param /filter filter-mapping filter-nameMyWebsite/filter-name url-pattern/*/url-pattern /filter-mapping Here is JkMount: IfModule mod_jk.c JkMount /myapp* default JkMount /myapp/* default JkUnMount /images default JkUnMount /IfModule If i could get this to work, I bet all of my hard to explain issues go away. Those JkMounts above result in 404 errors. I have no mod_rewrites of any sort that would be interfering. If I do this though, it works IfModule mod_jk.c JkMount /* default JkUnMount /images /IfModule I have no mod_rewrites or anything that would conflict. I am viewing the source of the WicketFilter and see the filterMappingUrlPattern which i why I included it web.xml init params, although it is not mentioned on the migration docs: http://cwiki.apache.org/WICKET/migrate-13.html#Migrate-1.3-FilterinsteadofaServlet . So, rather than confuse you any more, is it obvious from the the above why the Filter only works when I JkMount /* default ? If I could get it to JkMount /myapp* default, all of my relative path issues would most likely go away according to what you have explained. Thanks again Al Maw wrote: Chris Lintz wrote: Thanks for the response. Yes I am using Wicket 1.3 Beta 2. I First mapped the WAR at root, and let everything fall through Apache with JkUnMounts (i.e. JkUnMount /images default), but the issue is I could not solve the problem of I did not want / served by wicket. Basically it comes down to this. I cannot seem to make a reference to Wicket page on a path www.mydomain.com/myapp from my static home page www.mydomain.com because the relative path is / . I need the Wicket components to render under /myapp even from requests coming from / . OK. I'm slightly confused at the moment, because you haven't quite specified well enough how you're trying to achieve this. Please could you clarify the following points: - What context path is your app running in? Is it the root? - Is Wicket running using a filter or a servlet? - Is Wicket mapped to /myapp/* in web.xml? - What is your mod_jk forwarding set-up, exactly? - You say you're forwarding from www.mydomain.com to www.mydomain.com/myapp, but obviously you're not quite, as otherwise you'd just get an infinite loop there. ;) - Specifically, where are your wildcards if there are any? You seem to be concentrate too much on the specifics of what's wrong with your set-up, rather than what you're trying to achieve here. As far as I can tell, you want to do the following: - Run a Wicket webapp on http://appserver.com:8080/ (Note that's a root context path.) - Map Wicket to the root using servlet mapping/filter mapping of /*. - Pass requests from an Apache which land on www.mydomain.com through to the Apache, unless they land on /myapp/*, in which case send them to Wicket. - You don't want your static resources served from within Tomcat. Is that right? Even if that's so, I still don't understand what specific issue you're having. Actually giving us some URLs might be illustrative here. If you get a request for this: - www.myserver.com/myapp/path/to/mounted/page/ Assuming your context path is /, that will get mapped to: - appserver.com:8080/path/to/mounted/page/ If you add a HeaderContributor with a ResourceReferences, or something similar, Wicket will give you URLs relative to that, so something like this in your generated HTML: - href=../../../../resources/com.company.HomePage/foo.css This will resolve to the following in your browser: - www.myserver.com/myapp/resources/com.company.HomePage/foo.css ...which is perfectly correct, as obviously
Bookmarkable page and session object problem? (1.3 beta3)
Hi all, This seems like a bug to me but I am hoping some one can lead me the right way to a solution. I basically have non-bookmarkable page that puts the a User object in the session. After this, if i click on a bookmarkable page link, that page does not have the user in the session. If I go back to my non-bookmarkable page, the user is there. How can i get this bookmarkable page to see the same session object? Maybe this has something to do with Pagemaps. But in any case, the same session object should be available to bookmarkable and non-bookmarkable pages correct? thanks in advance -- View this message in context: http://www.nabble.com/Bookmarkable-page-and-session-object-problem--%281.3-beta3%29-tf4403473.html#a12562289 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Bookmarkable page and session object problem? (1.3 beta3)
Actually i just realized it has something to do with a stateless form. Maybe
you can tell me if this is a bug or not. I am pasting the code below, but
let me first explain. I basically have a LoginPanel that is included on all
non-bookmarkable and bookmarkable pages. My LoginPanel is using a
StatelessForm. I want this stateless form because generating a Session for
every request for simple login form is a crazy idea to me (especially in a
clustered session environment).
The problem is that it seems you cannot set objects in the session from
within the Stateless form. Although i implemented a work around by getting
the Page from within the stateless form and setting the User object on the
session from the Page itself. When I do so this User object is not in the
session on the non-bookmarkable pages I click on.
Here are the snippets of code (LoginPanel.java and WebPageTemplate.java)
public LoginPanel(String id)
{
Form f = new StatelessForm(lFrm)
{
@Override
protected void onSubmit()
{
try
{
User u = AuthenticationService.login(getUserName(), getPassword());
if (u == null)
{
feedback.error(Invalid login);
return;
}
feedback.info(You are now logged in. Welcome.);
((WebPageTemplate) getPage()).setUserInSession(u);
setResponsePage(getPage().getClass());
}
catch (AuthenticationException ae)
{
error(There was a problem logging in. Please try again later);
se.printStackTrace();
}
}
};
WebPageTemplate.java snippet:
public void setUserInSession(User u)
{
MediumSession session = (MediumSession) getSession();
session.setUser(u);
}

Re: Bug in IndexedParamUrlCodingStrategy 1.3 Beta3
Actually I just realized what causes this but have no idea how to get past
it. The InviteAcceptacePage has a Panel within another Panel. The nested
Panel contains a simple form submit button. The IndexParamUrlStrategy's
appendParameters() function is called with this Map parameters (from an
eclipse debug):
wicket:interface =
:4:moduleColumnPanel:moduleColumnFrag:loginPanel:loginBoxPanel:loginBox:lFrm::IFormSubmitListener::
Here is the appendParameters() function inside
IndexedParamUrlCodingStrategy:
protected void appendParameters(AppendingStringBuffer url, Map parameters)
{
int i;
for (i = 0; parameters.containsKey(String.valueOf(i)); i++)
{
String value = (String)
parameters.get(String.valueOf(i));
if (!url.endsWith(/))
url.append(/);
url.append(urlEncode(value)).append(/);
}
String pageMap = (String) parameters.get(wicket:pageMapName);
if (pageMap != null)
{
i++;
pageMap =
WebRequestCodingStrategy.encodePageMapName(pageMap);
if (!url.endsWith(/))
url.append(/);
url.append(wicket:pageMapName).append(/).append(urlEncode(pageMap)).append(/);
}
if (i != parameters.size())
throw new WicketRuntimeException(
Not all parameters were encoded. Make
sure all parameter names are
integers in consecutive order starting with zero. Current parameter names
are:

parameters.keySet().toString());
else
return;
}
The pagemap is null and the statement if (i != parameters.size()) evaluates
to true and generates the error.
Why does the panel with these Map parameters generate the error inside that
function?

Re: Bug in IndexedParamUrlCodingStrategy 1.3 Beta3
Yes I am using a stateless login form. Wow. Thanks for getting that
response out. I was able to see exactly where it fails inside the
appendParameters() function of the IndexParamUrlCodingStrategy (see my
follow up post). Now that you mention the stateless form, it seems it must
simply not know how to handle the Map parmeters sent in. As well the
pagemap is null.

StringResourceModel toString() changed in Beta4 - why??? Must use getString() now.
Hi all,
I swapped beta3 for beta4 and to my surprise all of my StringResourceModels
that have worked (even back to 1.2) suddenly dont work. The toString() call
no longer returns the resource String. I dont see this in the release notes
so to say the least, this was a very frustrating find.
For example, this use to work:
public String getPageTitle()
{
return new StringResourceModel(page.title, this, new
Model(this)).toString();
}
Now I have to say:
public String getPageTitle()
{
StringResourceModel(page.title, this, new Model(this)).getString();
}
A subtle change that that took some time to finally track down... Why did
this change? I believe the toString() is referenced in many docs.

Re: StringResourceModel toString() changed in Beta4 - why??? Must use getString() now.
I also read documentation - it may have been on the Pro Wicket book.. I dont recall. Nonetheless I thought it was strange to also reley on toString().. but seeing documentation and examples of toString() pushed me into using it without much thought. And like I said this worked all the way back to Wicket 1.2 . I dont care what it is.. I'll refactor to getString(). It would just be nice to know ahead of time whats coming.

I still would not rely on toString() for anything but debugging purposes unless someone passes me an object of a well known, final class right - but there are exceptions to rules. :-) In my case, the documentation for IChoiceRenderer.getIdValue() explicitely suggest using toString().

Button component bug - all uses of a Button cause a 302 redirect
Hey all,
We are quite puzzled why this is happening. Every use of a Button onSubmit
causes a 302 redirect no matter if it posts a form or does a get. I have
simplified this down to a simple page with a Button and guaranteed there are
no Apache redirects or .htaccess files in play. I also ensured the default
WebRequestCodingStrategy is used and the WebApplications
newRequestCycleProcessor() is not overloaded.
We are running Wicket 3 Beta4 inside Tomcat 5.5 (although I believe Beta3
has the same issue) . This only occurs with Buttons. Ajax posts and other
Link components make it through just fine. A Button as simple as this
causes the redirect:
Button testBtn1 = new Button(testBtn1)
{
@Override
public void onSubmit()
{
info(No response page );
}
};
Below is the proof a redirect is sent (with ourdomain.com in replace of our
real domain for privacy).

Re: Button component bug - all uses of a Button cause a 302 redirect
Ok. Its a good thing.. I didnt know it was the default setting. I guess i should thank you because it exposed a classic issue seen when having SSL accelerators proxying requests to port 80 . The redirect was redirecting off https. I have fixed this by setting correct headers at the accelerator box. Anyways, I don't need to change to ONE_PASS_RENDERER but for my knowledge going forward, it appears this cannot be set per request?

Is Beta5 coming soon? Beta4 has caused these issues for us....
Any chance of getting a Beta5 out soon. As luck would have it, Beta4 to say the least has been frustrating for us. So far beta4 has caused these problems in our app (all stuff that worked in Beta3) 1) AJAXLink is broke when using the Crypted URL encoding strategy. 2) StringResourceModel change on toString() method (this is fine, we refactored and are now using getString() ) 3) UpdateFeedback gone - http://www.nabble.com/1.3.0-beta4%3A-updateFeedback%28%29-gone--tf4707707.html 4) Pages are stateful now because of - http://www.nabble.com/Stateless-page-creating-session-tf4604432.html#a13147396 Any chance of getting a Wicket beta5 out with at least the stateless page fix?

Re: How To Change Page Store Size in DiskPageStore?
Guys I am on the same project so I can speak a bit more. The real issue is that on Redhat the default max directories is something like 32K. We ran out of file descriptors.

How can we limit the number of files and/or directories?

Matej, do we actually still need separate directories now that we use a page file? Yeah, we do. We are using one file per pagemap. I believe that the number of files can be limited as well as the number of directories.

This seems like a serious bug to me. I have yet to see a second level cache be removed unless a forced session invalidate() occurs. As far as I know, we do our best to delete those old sessions. AbstractHttpSessionStore puts a HttpSessionBindingListener in the user's http session when it starts so that the gets notified when DiskPageStore#unbind gets called by the second level cache session store and that should then take care of removing the files for that session.

Re: How To Change Page Store Size in DiskPageStore?
Ok here is a bit more clarity after digging further. Timed out sessions do trigger a removal of the of the PageStore file. However if Tomcat is restarted there is no cleanup of the PageStore files on disk. In other words the Page Store will leak those cache files and never clean them up. From these results, here are my questions now on all of this: 1) Shall we file a Jira for a enhancement to the DiskPageStore which would be a cleanup of any dangling cache files not part of the current DiskPageStore instance? 2) I am stlll trying to figure out how to limit the max number of directories and or files created by the DiskPageStore. I am less concerned about max sizes of sessions and page map and more concerned about the numer of directories/files - any ideas? thanks all for your quick responses and insight.

sessions are created (and hence Page store cache files) for an Ajax link.

Why is the link an ajax link?. Because in my eyes if you use ajax you
still
use the old page
and the ajax call just updates parts of the page. But if you do that. Then
ajax can't be that easy
stateless because how are you going to make exactly the same state as the

And ajax clicks should be lean and mean in my eyes because they should be

Re: How To Change Page Store Size in DiskPageStore?
That makes sense. Another thought that possibly makes it a bit easier is to name the page store directories with a unique process identifier. For example, if my session ID is B31598D4B206B75161AFE08FB5610D54.n1 and the process ID is 123456, then the Page store directory would be: MyWebSite-filestore/123456/B31598D4B206B75161AFE08FB5610D54.n1 With a structure like that it would be easy for a thread to remove the Page store directories that do not have the current process ID. Just a thought. Johan Compagner wrote: Yes the pagestore knows which files it makes, but it is not the controller of those files because the only thing that controls if the file must be deleted or not is the servlet container with the session objects. and as far as i know there is no api where i can ask which sessions are still active. So the only thing we could do is have a thread running that is waking up every day once and checks if there are files older then X. And that thread must be configured by you explicitly setting the timeout that you want to have. johan On Nov 14, 2007 12:04 AM, Chris Lintz [EMAIL PROTECTED] wrote: I think from previous threads there was discussion about something that you could do. For instance, the Page store should know what cache files it is controlling. By that logic alone it can deduce what it is no longer referencing and cleanup what was left form it. It seems silly to me to ask people to rely on graceful restarts or write your own cleanup script from a framework that created cache files. It seems fairly standard to ask clean up what was yours. I'd like to hear other input from average users. Johan Compagner wrote: as long as your server doesn't crash and isn't terminate by a kill -9 no files are leaked.. When that does happen then yes you have to clean it up.

Re: How To Change Page Store Size in DiskPageStore?
There are still other ways around this. If every process registered itself via unique file in a known directory and a Page Store thread touched this file every say 5 minutes, this gives more information to a thread to know whether or not delete a Page Store directory associated with unique ID. For example, MyWebSite-filestore/running_processes/uid1 MyWebSite-filestore/running_processes/uid2 MyWebSite-filestore/running_processes/uid2 Each Page store thread would then check the uid files that it did not create. For example, process 1 would check to see if uid1 and uid2 have been touched in the last hour (just making up something way greater than 5 minutes). If not, remove their associated PageStore files. I will admit this is a bit more involved, but i am trying to present a solution that doesn't require any configuration from a user perspective. Johan Compagner wrote: no it doesnt matter what id i generate or get. This is still not enough because it doesnt say any thing if i can delete it or not. i have an id 1 then i restart and i have id 2 can i then delete everything from 1? No i cant because there could be live sessions from 1. On 11/14/07, Chris Lintz [EMAIL PROTECTED] wrote: The process ID is just an idea for a unique ID.

Need to redirect to the current page upon a page expire - how??
Hi, So i have searched the forums regarding overriding RequestCycle#onRuntimeException(Page page,RuntimeException e) . It seems we are completely stuck because there is no way to determine what page threw a PageExpiredException . What I want to do is this: When my SearchPage expires, and the user again clicks a button search, they are immediately returned to the SearchPage potentially with any request parameters the user searched on. It seems the only way to get a custom Page when an PageExpiredException is thrown is to override onRuntimeException and return the custom page. Unfortunately the page is null when passed into onRuntimeException (which makes sense because there is no longer a valid session). How can i accomplish this within the framework? I hope we can avoid a hack like setting a cookie that represents the current page upon every page request. (atleast it seems to me there should be a framework solution for this). thanks for any ideas chris -- View this message in context: http://www.nabble.com/Need-to-redirect-to-the-current-page-upon-a-page-expire---how---tp15602103p15602103.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

That would work, except the search results do contain some AJAX functionality, which of course result in a stateful page.

Hey all, So the HybridUrlCodingStrategy is great for AJAX pages.

Re: How to lookup Page or Class from a URI path ?
Because I need the Class so i can check for the presence of an annotation
(@InternalPage). If that annotation is present, only internal requests from
10.x.x.x are allowed. Otherwise a 403 (Forbidden) will be generated.
Obviously i can control access with Apache, or a ServletFilter..heck for
that matter in the Page constructor itself. I feel the better solution is
with my annotation and before the Page constructor is called.
Thanks for clearing that up for me. Where can I check for this annotation
within the Web Request Cycle before the Page constructor is called?

Re: Invoulentary session sharing/leakage in Wicket 1.3.x
Guys has this been resolved?? We have been having some customers complain as well (some sending screen shots of others peoples data as proof). Because our users click streams are available publically at their control, we had thought jsessionids occurring in the click stream were being maliciously hijacked. We plugged that hole disallowing any jsessionid to be part of url (via Servlet filter) - yes this of course means JavaScript must be enabled. This involuntary session sharing is still occurring. We are running release 1.3.2. Johan Compagner wrote: I know all that, but i dont know how this could happen in wicket. I think it is user code because if you have a bufferedresponse that has a string buffer filled then it is very strange that the output stream is already used, i am very curios how both can be used by wicket in the same request, wicket only uses outputstream itself for resources and a redirect to buffer (the actual redirect) the last part this really cant happen because there shouldnt be anything in the response. The first part cant also happen because we dont render a page or something if a resource request target is the response target.. So it seems to me that that it is usercode that writes directly to the stream and let wicket still do something On 5/5/08, lars vonk [EMAIL PROTECTED] wrote: Hi Johan, This exception occurs if you obtained the servletresponse via the ServletResponse.getOutputStream() and are *trying *to obtained the writer via ServletResponse.getWriter() at the same time.

Jetty tracks this using an inner flag. This flag is only reset on the ServletResponse.reset() method, which I believe is called at the end of the servletrequestcycle. If I look at Wicket's the WebResponse class I see several ServletResponse.getWriter *and* ServletResponse.getOutputStream calls. You can't mix those two when writing the servletresponse.
