I passed part I with 83%. The exam is not very easy. There were 8-10 questions with 6 options. Sometimes difficult to choose from the options. One of the options was JMX. The following are the details : EJB 8-10 questions most of them on life cycle, when to use stateless and stateless session and when to use entity. For example there were scenario questions that required to store the reference. This scenario expected the option to be stateful bean. I did not get any questions on Isolation levels. There was a question on Transaction attributes. UML About 4 questions on navigability etc. Messaging 4 questions. Again concepts. Remember for some questions the answer itself was JMS I18n : 2 questions Security 4 questions There were various application scenario. I felt Java Blue prints and also Java 2 Network Security helped to some extent. There were questions on firewall being between a applet and terminal server. Remember which protocol on what port. Already mentioned some posts. Like the questions just say that the server listens on 443 and it is assumed we know which service listens at port 443. 1 question was on the features of firewall. EJB and legacy connectivity - 2 - 3 questions. Design patterns 3 questions. Reading the definitions from GOF should do. Also I had like to mention John Wetherbie's notes helped me for a question on Horizontal Scalability and clustering. And of course I give full credit for this forum for getting SCJP2 and SCEA Last but not the least one is required to read very fast. And also the following timing schedule helped me in keeping up with the time. 10 questions - 15 minutes 20 questions - 30 minutes 30 questions - 45 minutes 40 questions - 60 minutes 50 (48) - 75 minutes
Congrats! Madhu What's Next .... 83 is a Good %age . Throw some light on LoadBalancing & Clustring. & Also EJB Questions. Best wishes for Par II & III. regards Bidyut [This message has been edited by Bidyut Padhi (edited June 18, 2001).]
Thanks everyone. For load balancing, fault tolerance only the definitions will do. I got some definition from http://wwww.webopedia.com. For example for load balancing the link is : http://www.webopedia.com/TERM/L/load_balancing.html And also refer to Oreilly's JMS which says the Messaging Queueing domain is built upon clustering. "A queue may have multiple receivers attached to it for the purpose of distributing the workload of message processing. A sender could use this feature to distribute messages to multiple instances of an application, each of which would provide its own receiver. When multiple receivers are attached to a queue, each message in the queue is delivered to one receiver. " For clustering refer to : http://www.microsoft.com/ntserver/ntserverenterprise/techdetails/prodarch/ClustArchit.asp Also refer to microsoft DNA blueprint. I just went through this document before going to the exam. I did not get any questions on DNA. But some of them in this forum have suggested this. And for EJB be thorough with life cycle management, transaction levels, passivation issues, data access object (why and when they are used). The scenarios where a stateless SB is used and where stateful has to be used. Similar for Session and Entity beans.
Hi! Madhu, Congratulations!!! on your great sucess. Could you please tell me How to prepare for design patterns? I am going through book Design patterns By Eric Gamma .... but, I am just concentrating on defination, structures, consequences and related patterns of all the designs given. I am not giving much attention to implementation and sample codes given in the book. Please guide me how to study for design Patterns thanks shivani
Detailed study on Design patterns is not required. If you know the definitions that will do. I studied GOF for definitions and also Cooper for understanding the definitions (of GOF) thru examples (as this book contains Java examples). It is not required to implement these examples. HTH
I passed the first exam six months last year in october witn 86%, I did not get time after that. Now i have enrolled for the second part of it. The assignment, Is there anybody working on the assignment.
Dear Madhu, Congradulations to your success! Best luck to your effort towards the other assignments. Could you please describe what is the best book and way (excersizers) to prepare the first part according to your experience ? Thanks in advance. With the best respect. Ruilin Ruilin
I studied the following books : 1. Java Blue prints 2. JMS by Oreilly 3. UML Distilled by Martin Fowler (I have designed one project in UML) 4. i18n - from Sun's tutorial 5. JMS - Sun's tutorial 6. EJB by Oreilly (Chapters 2 to 8 and 10) 7. EJB by Ed Roman (Some chapters) Also CORBA and IIOP chapter. 8. EjB Code Camp 9. Java Network Security Chapters 1, 4,5,6, 8,9,14,15,16. Explains good about protocols, firewalls, design approach, OSI model etc 10. Design Patterns by Gamma (Only the definitions on page 8) and Design Patterns by Cooper (I understand from the examples as this book contains examples in Java) 11. Certification guide by Jamie Chapters 17 to 21. Contains information on Screen Scrapers, Upgrading Client tier, Middle Tier and DB tier. I did pratice from the Reference Implementation of EJB from the Sun's Site. I spent about 2-3 hours for 4 months and 8 hours for last 15 days. This norm may be different for different people. Less for some experienced people. And read all the posts (part I) from this forum HTH
Madhu in one post u suggested posted June 18, 2001 09:47 PM -------------------------------------------------------------------------------- Here is the link : http://classic.tep.ru/serge/computechinfo/java/sg242109_Java2Netw orkSec.pdf For user : guest and Password : guest But user name and passport is not working. Is that correct information ?.
What is the problem you are facing ? Are you able to go to the site ? As I am able to go to the link and giving the user name and password it is taking around 20 to 25 minutes for the pdf to be displayed. And also I have tried in Netscape. I was able to access now too.
Or maybe you can try this link giving the IP Address instead of classic.tep.ru as 220.127.116.11. May be you have problems accessing IP Addresses with 195 series from that side of the globe. Just my guess.
Have mentioned the books / material (11 of them) in the same link. I started off with Oreilly's EJB though there is no continuity between one book and the other. Each has its own objectives. It is only a matter of convenience. And moreover one has to study the material more than once to understand better.
Hi! Madhu, For Design pattern you mentioned to read Cooper's book for understanding the patterns in Java. I coudnot get Cooper's book and I was going through some other book which alogwithe the patterns defined in GOF it was dealing wiht GRASP patterns in Java which includes Lowcoupling/ high coupling, Expert..... Do I have to understand these patterns also or only one mentioned in GOF. shivani
Hi shivani For the exam you will only have to know all the patterns from GOF. In addition to that you should also know about the various senarios where those patterns have been applied in j2ee design (that is the tricky part), You dont need that book from Cooper, since I had that book and I didnt use it much. What I could help you is applying Design Patterns in develepment work - At least it helped me. Vivek Viswanathan
Umesh, I read oreilly's ejb though I have not read wrox. And vivek is right. UML Distilled is sufficient enough for exam point of view though UML by three amigos and Applying UML patterns are also good. Shivani, for design patterns I think that only definitions on page 8 from GOF is sufficient enough and also to know which patterns ejb Home, Remote and ResultSet follow. I will post the cooper link tommorrow. Thanks vishaka for the right link. HTH
Congratulations. I have also recently cleared scea part1. Now iam in the process of doing part2. in fact i just started 2 days back. if you also happen to start soon, then we can share our experiences while working. keep in touch. good luck
