Filter initalization on WebSphere #
On Websphere previous to 184.108.40.206, 220.127.116.11, and 18.104.22.168. there is a problem with filters - they are not initialized on web application startup; but on first access. In portal/portlet environment that might be a problem, for example when deploying some plugin).
In order to have servlet filters initialized on application startup (i.e. on deployment) you need to turn on this feature, by setting following webcontainer custom properties.
com.ibm.ws.webcontainer.initFilterBeforeInitServlet = true com.ibm.ws.webcontainer.invokeFilterInitAtStartup = true

However, thats might not be all! It make sense to delay execution of plugins web application, by setting the higher order. In WAS admin console select the plugin web app, go to Startup behavior and set Startup order to a higher number.
