Re: Communication between applications, one using wicket
Hello Cristi, this is typically referred to as diparate sytems communications issue. In the past I have had some success between such sytems using a WSDL and messaging. I did not have a lot of time so I opted for the Apache Axis2 framework (http://ws.apache.org/axis2/). You will have to do some work but better than developing something with low-level Java nuts-and-bolts. The systems I glued together were: a C/C++/Oracle backend concoction to a .asp/vbscript(ed) front-end. HTH, David.

Re: Communication between applications, one using wicket
Hi, there are probably easier way to provide a 'callback' channel to a remote system than a wicket page. Of course, using the web server makes sense, but I'd recommend to use a simple servlet to receive the callback and to update the specific database table instead of a wicket page, since the remote system probably doesn't need to get a html response - a simple http status code is probably enough. Using axis sounds like overkill to me...

Thanks for your feedback, guys. I don't like the idea of both writing to the database directly, because I want the layers separated. I don't think either application should know anything about the other's database.

Re: Communication between applications, one using wicket
Hello Cristi, it sounds like you mean polling. When I glued the two disparate systems together the Axis2 .aar file was just connected to an Oracle socket. The socket was in permissive mode so whenever the data appeared at the socket it was immediately available to the Axis2 listener and all the XML just went over the wire immediately because of some database trigger or other event on the DB side. The Axis2 .aar validated everything and acted accordingly to forward the communication to the .asp page. Just an idea. ;-) There are 10 kinds of people in this world: those who understand binary and those who don’t (Valid only for 2's complement). - Original Message - From: Cristi Manole cristiman...@gmail.com To: users@wicket.apache.org Sent: Thursday, April 9, 2009 8:14:43 AM GMT -06:00 US/Canada Central Subject: Re: Communication between applications, one using wicket Thanks for your feedback, guys.

I don't think anyone has a problem with the polling part of your solution. Unless your users absolutely can't wait for the polling interval to find out when the task completes then this is by far the simplest approach. Otherwise, you're into some sort of comet solution, where you keep an HTTP channel open to your server and a thread waiting at the other end to be woken up and reply the second the task is completed. jk - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Package all CSS and JS
I think that I didn't explain it right. What I want is that wicket concatenate all included javascripts into one file. Something like wicket:link link.. javascript1.js / link.. javascript2.js / link.. javascript3.js / /wicket:link Generate just one resource with javacript1.js, javacript2.js and javacript3.js concatenated. The reason for that is to reduce the number of requests.

Re: Turning off ModificationWatcher
it is much simpler and more efficient to set proper caching headers. concatenating resources often does not work because different components on different pages contribute different resources, so there are a lot of variations of these huge files you may end up with and would have to stream to the user over and over. yes, it would only be one request per page, but it would be a huge one over and over as opposed to being able to cache a lot of small resources and never request them again. -igor On Thu, Apr 9, 2009 at 9:00 AM, Matt Welch matt...@welchkin.net wrote: Thanks.

Re: Can client cache pages effectively?
A quick follow up in case anyone else was curious about how this is going: I ended up using ehcache page cache filter for a simple page that just displays 'current' items (calendar view of events) based on a db query. No forms (state) on this page so it works pretty well. In my DAO that does updates, I clear the cache. Very simple, works great. (Only catch I ran into is that my menus change when I have a session and I'm logged in as super-user, so I have to make sure I don't let that version of the page be cached - I do that by adding 'super' page parameter so URL is different and filter is set to only cache the 'normal' version. So, that still leaves me with my main catalog page, which is primarily a similar list of items, but it also has some active content (in particular, a search form). So my bright idea (tm) (i.e. I'd love to hear critiques before I get too far along with it) is the following: Make a new page for just the data grid, with page parameters including the search string and last-modified date (and super-user login because I get some edit links and such with that). Mount it and ehcache it, and override setHeader so it becomes client cache-able. Then, my outer catalog page with the search form on it just uses an IFrame to display the grid data (easy to keep track of last-modified globally). Same clear method in DAO dumps the cache whenever a change is made. Also, I'd want to make a robot no-follow thing to avoid google trap on that page. Could this actually be a legitimate use of otherwise dodgy IFRAME ? Sound like a good plan? Thanks, -- Jim.

Is there an easy way to flush after you send the /head tag? http://developer.yahoo.com/performance/rules.html#flush I don't know if this is premature optimization or just hoping for magic speed up from simple fixes... but it is worth a shot! thanks ryan - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
debugging a Wicket application running under Jetty-6.1 in Eclipse
Hi, This is about debugging a Wicket application running under Jetty-6.1 in Eclipse. I followed the steps shown at: http://docs.codehaus.org/display/JETTY/Debugging+with+the+Maven+Jetty+Pl ugin+inside+Eclipse But I am getting this exception: java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher Exception in thread main Any help? The steps I followed are: Step 1 Go to the Run/External Tools/External Tools ... menu item on the Run menu bar. Select Program and click the New button. On the Main tab, fill in the Location: as the full path to your mvn executable. C:\java\DEVTOOLS\MAIN\maven2\bin For the Working Directory: select the workspace that matches your webapp. For Arguments: add jetty:run. Move to the Environment tab and click the New button to add a new variable named MAVEN_OPTS with the value: -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=y If you supply suspend=n instead of suspend=y you can start immediately without running the debugger and launch the debugger at anytime you really wish to debug. Step 2 Then, pull up the Run/Debug/Debug ... menu item and select Remote Java Application and click the New button. Fill in the dialog by selecting your webapp project for the Project: field, and ensure you are using the same port number as you specified in the address= property above. Now all you need to do is to Run/External Tools and select the name of the maven tool setup you created in step 1 to start the plugin and then Run/Debug and select the name of the debug setup you setup in step2.

Re: debugging a Wicket application running under Jetty-6.1 in Eclipse
I'll suggest to do it in the Wicket Way, you will have much more benefits. If you made your project from the QuickStart, you will notice a 'Start' class under your 'test' source. that what it does is just start an embedded jetty pointing to your webapp directory and mounting your application under / context. so just right click on it and click Debug as - Java Application and you're done. Even if you are working on a multi-module maven project this will work, just make sure your module are installed on your local repository, issuing 'mvn install' on the root project. If you have question regarding the 'Start.java' class just let us know. mchenini wrote: Hi, This is about debugging a Wicket application running under Jetty-6.1 in Eclipse.

Re: Turning off ModificationWatcher
Na, nothing catastrophic will happen, or else you won't be able to development your app using development configuration...HOWEVER...the performance of your app is likely to double when running in deployment mode, some exceptions won't be visible to the user (i think component-in-use-check and others), serialization checks won't slow you down, that kind of stuff. If you look at the WebApplication class, you will find lots of getters like getRequestSettings(), getApplicationSettings() and so forth, from what I know, development configuration is a defined set of these configs which sorely focus on helping you while developing, but they won't help you at all while running in production mode, cos they're not optimized for that. On the other hand, deployment configuration is a defined set of these configs which sorely help you getting performance and be in production. It's like running your app with logging on trace level when in development...If your app is any good, it may be it won't harm you at all (we had an app out in production running in development mode for weeks), but your performance will suffer for sure. bw, Martin 2009/4/10 Sam Stainsby s...@sustainablesoftware.com.au: On Thu, 09 Apr 2009 08:41:20 +0200, Martijn Dashorst wrote: Never *EVER* deploy your application in development mode.

wicket:link behavior changed in 1.4r2
Hi, I'm trying to upgrade several sites from 1.4m3 to 1.4r2 and have hit an issue with the AutoLinkResolver. We have lots of html with linked images that look like this: wicket:linka href=SomePage.htmlimg src=/some/full/path/ image.gif //a/wicket:link This used to work fine, but with the last couple of releases (r1 and r2) clicking on the image directs the user to a blank page with the image on it rather than the intended page link through a javascript onclick action. Ideally I'd like to turn off processing of img tags by the AutoLinkResolver and only have it process href's, but I can't figure out how to do that from the javadocs. Can someone point me in the right direction? Going back and setting each of these up as a BookmarkablePageLink is not an option, we need the auto linking behavior.

Re: Turning off ModificationWatcher
Oh, it's MUCH worse than even that. Every single component constructed by your application will get a complete Java stack trace attached to it at the point of construction. Not only does that seriously damage your performance, but this stack trace also takes up space! This is why we warn you about not deploying in development mode on startup.

Re: GWT vs. Wicket?
There is no real easy way, but to do it :) I find the hardest thing about Wicket, particularly when your first starting out, is discarding all the old ideas about how a webapp is built... Having worked in the field for a long time, servlets, JSPs, Struts, etc. it took me a while to get over the old patterns of doing things and start thinking more wicket'y I still have trouble with WIcket now and then because there *is* quite a lot of complexity when your doing something non-standard, however I usually find that the answer is the obvious one and trying something usually works... and when I think about it, i realize that the same non-standard thing i was doing would have taken just as much time in any other framework to sort out. What I love wicket for in particular, is the very good separation between view and controller/model. no more crap logic in my HTML! Yay. Anyway, i'll continue to use both GWT and Wicket. - Brill Pappin On 8-Apr-09, at 9:24 PM, ying rss wrote: I played with both GWT and wicket.

how to control the required validations before the validation process is started
Hi, I need to control the required validations set on the components dynamically depending on the value of the other element (ex: selecting a radio button should trigger required field validation for some elements). For this I extended the components, and I m dynamically adding or removing the required validation even though the required validation was set in the constructor. I tried calling the validations controlling method in the onValidate(), validate()... but before the control comes to my method, all the validations are happening. Is there any method while will be called before the validation process is not yet started or just before the validations are checked, so that I can control the validations dynamically.
