Amazon.com is selling their stuff as well

And there are two comments from highly "satisfied" buyers:

About WebLogic Developer Certification Study Guide by ePlanetLabs:
This product is a fraud. After buying it directly from eplanetlabs.com I received a 464 page document which, by no means, fullfils the necessary content for the BEA developer certification (see links at http://certification.bea.com/certification/dev_certification_reqs.jsp). This certification has three sub-areas: build, portal and integration. The so called guide has some questions, some pages explaining very generally web applications, controls, jpd's and jpf's. It states that those sections will be fully detailed later on the book, but this never happens. Not even a decent section on portal and integration! It has screenshots for weblogic version 6.1, when the certification is on version 8.1. And most of the document (more than 200 pages) are a copy&paste from weblogic administration 7 FAQ! Not to mention that guide on Cactus (what does it have to do with the certification test?!). It is outrageous how these guys have the courage to publish such a piece of phony! (pasted from here)

About RHCE Study Guide by ePlanetLabs:
This solution guide was junk and a waste of money.... It's basically a stream of conciousness pdf file that doesn't contain much relevant information.... In fact a lot of it doesn't even pertain to Red Hat. None of the information is relevant to preparing for the RHCE exam, in fact I showed it to one of my Red Hat instructors and we had a good laugh at just how bad it was. Don't waste your money.... I'm sorry I did. (pasted from here)
