Re: Openlayers, openstreetmap and markers

What could be going on here? There is a tutorial somewhere on the OpenStreetMap Wiki. The boundaries have to be computed using some magic (but deterministic) values that are given in that example. Unfortunately I cannot find the reference now. Here is a link to an example in German: http://www.cognitiones.de/doku.php/osm_openlayers_test It says that the magic number 20037508.34 is related to the conversion between tile numbers and coordinates. Unlike in this example the attribution link should be enabled in the display. The OSM-Javascript files provide it already but it has to be enabled: map.addControl(new OpenLayers.Control.Attribution()); Regards, Frank - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Creating a page hierarchy
Hi, is there one established way to generate a page hierarchy? Or some best practices? I like to have a website (also a dynamic one) organized in a hierarchical way like traditional static websites. This way users can go to their desired functionality quickly and may be able to even remember the associated URL. I assume I have to use bookmarkable pages somehow. Some questions remain for me: 1. Do I have to mount each single page or is there some wildcard/regexp/inheritance mechanism like in Django? 2. How do I organize my source files? Does it make sense to reflect the site hierarchy in a package hierarchy? 3. The site I develop has to use authorization. Is it possible to get a user back to the bookmarked page that he accessed after asking for authentication? I think yes, but am not sure.

Re: JPA EntityManager storage
Hi Adrian, > - Are you setting your entity manager on the threadlocal during > onBeginRequest by putting it on or relying on the inititalvalue for the > threadlocal. I think you hit the problem here. The example I used (in German at http://rattlab.net/2008/10/persistenz-fur-den-feedreader/) implies that every Request uses its own thread and I never expected threads to be reused. I used simple initialization of the variable and closed the EntityManager in onEndRequest(). That highlights why I didn't like the ThreadLocal() approach - it depends on implementation details somewhere out of my control (and knowledge). Thanks to all who answered - also the discussion about Spring/Guice/whatever was informative (and entertaining). Expect to get some beginner questions from me again soon :) Regards, Frank - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Long JPA-Transactions (was: JPA EntityManager storage)
> Yes, but not all transactions are request-scoped. We have many times > implemented asynchronous transactions, because the user didn't want to > wait for the results. Can you give a (high level) overview how to handle such a situation in Wicket? I'm sure clients will demand such functionality someday from my application. I would use some kind of batch processing system with API calls to get the status of the batch request. Or would this be overkill?

Re: JPA EntityManager storage
> Well when it comes to EntityManagers be sure to close, commit and > clear your threadlocal instance after your service request cycle. Exactly that didn't work for me. I checked for open transactions, closed them, closed the EntityManager and even released it by setting the ThreadLocal variable to null. Although I created a new EntityManager in onBeginRequest() I constantly got errors during form processing because of not existing EntityManager. I solved this by leaving EntityManager there after the request and checking for its existence at the begin of the request. Any ideas about this?

Re: JPA EntityManager storage
> You may find these of interest: > http://javanotepad.blogspot.com/2007/08/managing-jpa-entitymanager-lifecycle.html Yes, if I need that level of flexibility (which I don't need).

Re: JPA EntityManager storage
> Don't fall into the trap of premature optimization! Hm. Maybe I'm in this trap already. But what is wrong with binding a resource directly to the request when it is used exactly for the lifetime of the request? For me this only sounds logical compared to the pragmatic approach using a ThreadLocal object. Are there any technical reasons against storing in the request?

JPA EntityManager storage
Hi, would the Request object be a good place to store a JPA EntityManager? It would be created in onBeginRequest() and destroyed in onEndRequest() of the RequestCycle object. I saw two other options already: - use a filter in combination with Spring (I don't want to use Spring yet - this would add to all the new stuff I have to learn so far) - use a ThreadLocal object like in http://rattlab.net/2008/10/persistenz-fur-den-feedreader/ in the class JpaUtil. I don't like this approach because it depends on the implicit assumption that each request is handled in a thread (this depends on Wicket implementation details, therefor I dislike it) Any advice is welcome.

Generics in components
Hi, I am still very very new to Java and Wicket of course too, so excuse me if this is a dumb question. I swiched my project to Wicket 1.4-rc4 now and got all these wonderful warnings about the "Raw types" of the components in my sources. Are there any examples that highlight the handling of the generic component types? I have no clue what type parameter I have to give a form component for example (no clue for other components too). Should it be the class of my model or anything else? For validators I tried to set base types (Integer, ..) and this worked. But still I have no clue if this is the right thing to do. Confused ... :) Regards, Frank - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
static content / two jetty contexts?
Hi, I got a Wicket project set up with Maven and work with it in Eclipse. I like to deliver static content through a webserver directly (lighttpd in this case). I do this also for the CSS framework that I use (YAML). Now there ist the problem to include the static content during the tests. I package my application with an embedded Jetty server in a jar file to make deployment simple. For the tests I use the maven-jetty-plugin to be able to server the static content also. Until now I can either get dynamic content OR static content. So my question is how to combine both (I have no experience with servlet containers and web.xml). I tried to understand the jetty documentation, but with no success :) Any hint would be good. Here is my plugin configuration: org.mortbay.jetty maven-jetty-plugin / ../website ../tp/src/main/webapp/WEB-INF/web.xml And part of web.xml: wicket.tp /* With kind regards, Frank - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Maven setup
Hi, does anybody have a Wicket quickstart project updated to the latest versions? I am new to Java, to Maven and to Wicket of course too. I have a background in web developing with Zope and Django (all implemented in Python) but am forced to use Java now. I know that the learning curve will be steep and I got some showstoppers already :) After reading much about many Java frameworks and some frustrating tests with JSF I've chosen Wicket because it fits my requirements best. I've done some tests with databinder which promoted Maven heavily, so I want to use Maven too. I'm still struggling with the whole setup - the following issues are still not clear to me: - Maven setup - Wicket dependency doesn't work for 1.3.5 nor for 1.3.6 although the website says so (data at the end of this message) Possibly another repository required? - integration with Eclipse - Maven goal or Eclipse plugin or both? - I want to use embedded Jetty also for production (running the application behind lighttpd). How to do deployment in an elegant way? There is only SSH access to my server. - Hibernate integration - does databinder help much or is it better to learn Hibernate directly? I saw that databinder always is somewhat behind the current versions, so that may be an issue. I hope these are not too stupid questions and someone will find the time to answer them.
