Let us break down your use case a bit more; right now we load and save a project / map / layer data structure from disk.Are you looking to save everything in the database? Or are you looking to "override" part of the normal load/save process and force some centrally defined styles onto an already existing Map?
Can you give me your requirement in user terms? Back to your technical question - please review the following class: - http://svn.refractions.net/udig/udig/trunk/plugins/net.refractions.udig.style.sld/src/net/refractions/udig/style/sld/SLDContent.java This should provide enough detail for you read in a blob of SLD from your database and apply it to an existing layer.
