Hi all,
I am an SCJP and am now beginning to prepare for SCJA.I have gone through various resources on the net.Many cover the topics like EJBs,DesignPatterns,UML etc but could some one please suggest a good resource(s)(a book or an article ,link etc) for legacy connectivity and JMS?
TIA

Well I have heard that Jaworski's book covers legacy connectivity part really good. When it comes to JMS, you can read JMS specs from Suns's site but there will be no questions that require You to know them. Most likely You are going to get a question that describes a scenario and one of the possible answers is to use JMS. So I would suggest to You that You think when is a good situation to use JMS.
Hope this helps.

Vladan, you mean we don't need to know the detail about JMS, is that right

I think what Vladan means is that we needn't have in-depth knowledge abt JMS but nevertheless we do need to know why,where and how it is used.A broader perspective is needed here since the exam covers mostly various scenario based questions.Am i right Vladan?

Yes, You are right. But JMS is not that big topic anyway. Make sure You know what is Publish/Subscribe and Point-to-Point for Your own good. I really don't think You are going to get any questions specifically on those two. Know the advantages of JMS and use common sense to determine when is the right situation to use it.

I agree with Anil. I recall hearing that JMS was mentioned in the exam so I downloaded the JMS spec. As I recall I only needed to read the first 2 or 3 sections to get the level of detail covered on the test.
