I'm expanding on an earlier post where I explained how to deploy JAX-RS Web Services to the Oracle Cloud. In that entry the web service simply returned a hard-coded "Hello World". In reality, you most likely want your web service to expose something more meaningful. In this post I'm going to expand the HelloJerseyApp to display the results from a table, which I'll expose using a JPA...

That is, however, assuming the Id is of a simple type (I'm a firm believer that primary keys should be of a simple type, unrelated to the data they index.). However, if you find yourself in a situation where you must use a composite key (hopefully this is only because you're connecting...

Another one of Seam's compelling features is its ability to manage "conversations". A Seam conversation provides fine grain control over the traditional HTTP session scope so that "concurrent conversations" can occur in HTTP session, which usually occur when users open another browser window or tab. The problem is best described with an example. I've added a confirmation...
