You always have the refund option. In addition, I confirmed from whizlabs marketing that you also get the 8.1 upgrade (of the simulator) if you choose to go for 8.1 certification after doing the 7.0.

About the explanations, they represent a lot of value to the content. In a way you could learn a lot from the 500 questions, even if you go through the questions and explanations. Obviously it is not a substitute for the actual theory you need to know, but its great in clarifying differences in answer choices, which can be key to getting through the exam.
I think about 4-5 questions in the exam are on Web services. The simulator provides about 30-35 questions on Web services alone. In addition there are revision notes for last minute revision before the exam.
Since WebLogic 8.0 is out and i guess WebLogic 8.0 Exam will be out soon. If someone bought the Simulator for WebLogic 7.0, can he upgrade it to version 8.0 FOC since he changes his mind to take the latest exam?

I found this question very reasonable and I checked with marketing before I got back to you all....and there's good news! There is an upgrade program and so if you buy the Whizlabs 7.0, you get an upgrade for 8.1 for the next 6 months. So thats really excellent news for those thinking about 7.0 or 8.1.

Yes, take a look at the link.
In addition, in terms of getting basic understanding, you would need at least a month or more (depending on how fast you pick up). Then you will need to know WebLogic across the board. That will take more time.
Playing with the application server samples is a good start. You have worked with Sun One, so you understand the basic deployment descriptors like web.xml, the war and ear deployment and basic J2EE development with EJB, JSP, web sevices, etc. WebLogic has its own features in addition to J2EE, its tools and utlities, clustering, administration, etc.
Since you are new to WebLogic, plan on at least 2 months for preparation time. Using the simulator with other online resources, can help you prepare better. You can use the whizlabs simulator to understand the kind of likely questions and validate your skills at various points. The feedback will also help you focus on areas of concern and make the process faster.
It may be quite a few months before the 8.1 simulator is out. Also add a month or so to prepare and get ready after that. If you are looking to get certified in the next month or so, and have good J2EE background, I would suggest 7.0.
Thats a good question. WebLogic 7.0 already supports EJB 2.0. In fact most questions in the whizlabs simulator assume EJB 2.0 and specify EJB 1.1 wherever applicable.
To reduce confusion, I would now like to differentiate between the changes in the product (7.0 and 8.1) and changes in the WebLogic Developer exam (7.0 and 8.1)
Changes in product:
As far as the product 8.1 is concerned, there isn't a big difference between 7.0 and 8.1. If you have expertise on 7.0, that works for 8.1 as well. There are certain new features which 8.1 brings, but they are not as dramatic a change as they were from 6.1-> 7.0. I worked on both 7.0 and 8.1 on a project and migrating from 7.0 to 8.1 was easy.
Changes in Developer exam:
Now when it comes to the exam itself, BEA has changed the structure of the Developer exam to be more focussed on developing using WebLogic Workshop. It doesn't have the broad scope that 7.0 did. For example it does not cover basic administration, that 7.0 exam did. I also see the 7.0 exam being more J2EE oriented and 8.1 exam being more BEA oriented.

To answer your question about BEA endorsement, the only endorsement is that the author (in this case me) is BEA certified on 7.0. Having passed the exam and knowing the style and content of the exam, I was able to build the content to guide others.
The WebLogic 7.0 exam's scope is very broad. It covers almost all of J2EE, Web Services, development, deployment, administration, troubleshooting, etc. So if a person passes this exam, it means that the person has a good command over WebLogic and can work in real-life situations.
Note that to pass this exam, it is important that you have already worked hands-on with WebLogic Server (even if it is just the free download and small applications you build on your own). In fact I would higly recommend that for people who haven't worked with WebLogic Server before.
Hope that helps.
To add to what Siva has already mentioned, the style and content of the questions are tailored to the actual WebLogic Server 7.0 exam.
Questions are tricky and picking out the right answer choices can get tough. If you have ready theory, but not practised a lot of questions with mulitple choice answers, it is likely you will miss on many questions. The large number of questions covered in many mock/Licensed exams is to give you the edge you need to get through. Besides, the money-back guarantee protects you in the rare case you dont get through (past whizlabs simulator success rates are amazingly good).
Just to make it a little clearer, the 8.0 focusses more on WebLogic Workshop and 7.0 is more on J2EE lines covering most aspects of the application server, inclusing WebLogic specific features. Whizlabs provides the 7.0 simulator, which (from what you mentioned about non-IDE stuff)would be what you are looking for.
The Whizlasb 8.1 simulator will be tailored for the 8.1 exam and will be somewhat different in content from the 7.0. That follows from the fact that the 8.1 objectives are focussed more on development using Workshop.

I would like to add that you could use a book but the study guide online is great (again refer to my article for the link). As far as the number of mock questions are concerned, I think they are approximately around 500. I would say, that in addition to helping you pass the exam, these questions are a great way of validating your own knowledge while going for an interview, etc. Since the answers and explanations are all there, you are sure that you know it right eventually.

You will need a combination of things here:
1) Personal hands on experience with the product. You can work with sample applications (WebLogic download is free form the BEA web site).
2) Theoretical knowledge (books, online study guide, etc). I would recommend reading my preparation article for some pointers:
3) Understand, practice and validate your knowledge against the kind of questions the actual exam will throw at you.
This is where the Whizlabs simulator plays an important role. The simulator provides a huge set of questions based on the kind of questions asked in the actual exam. It provides explanations on correct and well as incorrect answers, which is by itself a good learning experience. With whizlabs past record, working with the simulator will highly increase chances of (if not ensure) success in the exam.
The WebLogic 7.0 exam doesn't go into WebLogic internals. In fact it is pretty close to J2EE. It does go into WebLogic specific features, utilities, tools, etc. For example, you would need to know about how to use the admin console for managing, monitoring, configuring WebLogic Server. If you have been using WebLoigic for 2 years, I would say you have a pretty good chance, if you prepare for it, using recommended resources. The 7.0 simulator focusses on the kind of questions which tend to come in the actual exam.
I hope that answers your query.
There are differences in the structure and objectives of the 7.0 and 8.1 tests. WebLogic 8.1 as a product may be better than 7.0. However for those who are taking certification exams, here are a few things to note:
1) Many organizations may still have 7.0 and may not care whether you have an 8.1 certification.
2) 7.0 test covers a little bit of everything and as such is a well rounded test (in my opinion). In 8.1 a lot of emphasis is on WebLogic Workshop, which is not necesarily bad, but it represents a learning curve for those not familiar with specifics of these products and are more of J2EE developers. For those people, 7.0 would be much easier to tackle. The 7.0 test is not due to be retired until 2005 as far as i understand.
So there are trade offs between taking 7.0 or 8.1 certification. I would still recommend 7.0 for those that want to get a quick certification, since there are resources available.
For those willing to wait, I am sure there will be additional resources for 8.1 ( for example the whizlabs simulator perhaps due in a few months).
Check that you have SSL configured correctly on the admin server and that the CA of the managed server certs are trusted by the admin server.
By electing to have an administration port, you have elected to use SSL between admin and managed servers. The erorr you are seeing, seems to indicate that the admin server has a problem trusting the managed server's certificate.

So you have an isolation level set on your DB and you have isolation levels on your EJBs. I think WebLogic internally sets the isolation level on the connection used. This is also something you can do if you write direct JDBC code using the Connection object. This over-riding of isolation levels appears to be standard.
So I think you should be fine. In case, no isolation level is applied at the application level, the default (database) isolation level holds.
