When developing an application using JBoss Seam on eclipse I came across a strange problem. When deploying an ear project with seam components the datasource configuration file ending with -ds.xml was no longer available in the add remove dialog although it was present in the resources directory within the ear project. When going through this blog I found that the easiest way to do that was to mark the file as “deployable” by right-clicking on the -ds.xml file and selecting “Make Deployable”. Voila ! the -ds.xml file starts appearing in the Add Remove dialog..
