SCJA is for an "Associate." The exam is higher level overview of Java's capabilites (micro, standard, and enterprise) without going into detail on how everything works. My understanding is that it's intended for people who will work with Java, but not actually be doing the programming -- for example, project managers.
SCJP is for a "Programmer." The exam covers language foundations in detail and is a prerequisite for more advanced exams (like web component development). If you are a programmer, this is generally the place to start.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
