I hate expired sessions, death to all expired sessions. Traditionally a Java servlet container has a fixed session time, a flood of traffic can potentially cause JVM OOM errors if the session time is set too high. I wanted a smart session container that can hold onto sessions for as long as possible and expire […]

I’ll start this post off with a quote from IRC ivaynberg: you cant build good looking sites with wicket victori: lies ivaynberg: or public-facing sites I have to admit that Wicket appeals more to the “backend” programmer than to the front-end design conscious developer. For every good-looking Wicket site out there, there are ten abysmal […]

I finally got around to open sourcing our scala memcached implementation that we use at fabulously40 for session storage. Since wicket sessions can vary greatly in size, using the standard memcached server implementation became impractical due to the slab allocator. The current code on github lacks the ehcache store and an Actor IoHandler adapter. The […]

One of the first few things I have tackled while creating fabulously40 was stateless pagination. I wanted to keep all the public facing pages stateless to avoid session overhead. Wicket makes pagination brain dead simple at the cost of session use. I wanted to keep the simple programming model yet be completely stateless. Here is […]

I am about to run out the house for the Labor Day weekend, quickie post on my new coding url strategy. MixedParamHybridUrlCodingStrategy lets you keep stateful multi-pagemap URLs clean while using mixed parameters. Example… mount(new MixedParamHybridUrlCodingStrategy(“/questions”,QuestionsPage.class,false,new String[]{“cat”})); This will mount “/questions/stupid-category” and convert it to… new PageParameters(“cat”,”stupid-category”); package com.base.target.coding; import java.util.HashSet; import java.util.Iterator; import java.util.Map; […]

Wicket is a wonderful framework for building complex web applications. However, it is all too easy to hang your self with session use in Wicket. Wicket manages the session on your behalf so you don’t have to worry about UI state. Since every page is serialized to the session, you need to be extra careful […]
