Wicket atmosphere initialization exception

由 为君一笑 提交于 2019-12-08 18:06:32
I have the following setup: wicket: 6.1.0 wicket-atmosphere: 0.4 (via Maven) On Application.init() I get a NullPointerException during instantiation of EventBus new EventBus(this); Exception: java.lang.NullPointerException at org.apache.wicket.atmosphere.EventBus.<init>(EventBus.java:105) This is caused because the method public synchronized static BroadcasterFactory getDefault() delivers null (the protected static member "factory" is not initialized). How do I use Wicket/Atmosphere properly? Did I forget something to initialize? I'm starting Wicket as a ServletFilter. <filter> <filter-name

Wicket Authorization Using MetaDataKey

由 安稳与你 提交于 2019-12-08 15:42:33
I am trying to implement a simple authorization strategy for my Wicket application. I am implemented my own AuthorizationStrategy (extending IAuthorizationStrategy). http://old.nabble.com/Authorization-strategy-help-td18948597.html After reading the above link, I figured it makes more sense to use metadata-driven authorization than one using Annotations. So I have a simple RoleCheck class public class RoleCheck { private String privilege; public RoleCheck(String priv) { this.privilege = priv; } public void setPrivilege(String privilege) { this.privilege = privilege; } public String

Why doesn't my Wicket Panel rerender after changing the default model?

由 牧云@^-^@ 提交于 2019-12-08 10:13:56
问题 When the page with the MessagePanel first renders, the message and the approve link render perfectly. When I click the approve link, all the business logic works as desired, the getNextMessage() method returns the appropriate object, but the message panel does not update on the page in the browser. That is, the message body Label does not update. JPAEntityModel extends LoadableDetachableModel. What am I missing? And how do I fix it? public class MessagePanel(String id, IModel<Message>

Wicket Dynamic Resource Displayed in HTML

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-08 07:39:23
问题 I have a Wicket page which will dynamically display an image. Let's say the image is the current date/time. In HTML, I would have something like <img src="[dynamically generated]"/> Assume I have a utility method which returns to me a byte[] of the current image. public byte[] getCurrImage(); How do I implement this dynamic resource in Wicket (HTML/Java)? I can't mount a shared resource because the image will keep changing all the time. Do I need to save the image somewhere? Thanks 回答1:

Wicket - getting body of markup element

由 試著忘記壹切 提交于 2019-12-08 07:22:35
问题 Assuming I have markup that looks like this : <span wicket:id="text">Some text that I'd like to read</span> Is it possible to get the content of the body of the tag somewhere, or is it irremediably stripped by wicket? Edit : My intent is to implement some kind of simple CMS. Users need to be able to enter LaTeX formulas, in the form of tex>a^2</tex> that I would then render with a RenderedDynamicImageResource. Other tags need to be interpreted in a similar way. I envisioned to do it in two
