For our purposes, the Weblog entity is a list of available weblogs. A “Weblog” object has the following properties – an id, a username (for the user who created the blog), a dateCreated, and a blogTitle. Every Entry object has an id, a text, and a timeCreated property.
The first thing to do is create some objects to persist. Let's create both a "Weblog" object and an “Entry” object (in the src/dao/**/model directory). Basic XDoclet tags for these entities are show as well.

In this example, the ''Weblog'' object is used to indentify a person's blog. This class has the following properties:

The ''Entry'' object is used to contain a listing of a person's blog entries in their Weblog. This class contains the following properties:

The first thing you need to do in this tutorial is these two object to persist. Create both a ''Weblog.java'' class and an ''Entry.java'' class (in the src/dao/**/model directory). The necessary XDoclet tags for these entities is included on the ''getter'' method's javadoc.

The many-to-one relationship between entry and category can be established using XDoclet tags. Hibernate relationships can typically be established on either side of the relationship or as a bi-directional one as well. For our purposes,this relationship will be maintained by an extra property and collection held by Entry. The list of possible categories for a weblog entry will eventually be represented as a drop-down on the UI.
