It also lets you show an earlier pass to your employer to show you are on the right track. That gets you certified at the associate level in Java 8. To be certified at the professional level, you have to take OCP 8 or the upgrade exam. The upgrade exam is a lot harder than the OCP 8. There are two reasons for this:

A good number of the easier topics on the OCP 8 aren't on the upgrade exam

Oracle has some OCP 7 topics on the upgrade exam. These were taken off the OCP 8 but on the upgrade exam. So there is more to study for.

As you can see, I recommend you take the OCP 8 after you pass the OCA.

Ericson: You should study the whole book and not just the appendix. Because even if they aren't explicitly testing a concept that isn't on the upgrade, it is fair game for them to use in practice. You should of course spend more time on the upgrade topics. That said, you probably already know a traditional try block requires a catch or finally so will get through that material faster.

Thanks for this reply Jeanne. What I needed. So would it make more sense for me to do OCP8, and not the upgrade exam? Or will this mean I'll have to do the OCA exam prior as well?

Ah ok. I guess then for you it's probably best to take the approach of starting from scratch, just to make sure you cover everything you need for both exams. For me though it will be different I think.

Norbert Reding wrote:Also for me a very interesting question.  2011 I passed OCPJP Java 6 and now all java developers in my company have to pass OCA and OCP certification for Java 8.  For OCA I choose the new certification.  But for OCP I'm not sure which way I should  choose.

If the company objectives are to get everyone to OCP level, then many would require doing OCA I assume. But doing OCA isn't required for you then as you have passed OCPJP.

Hey,

Having taken the SCJP exam many years ago for Java SE5. I'm keen on upgrading to Java 8 with the 1Z0-813. I have purchased the Sybex OCP book which covers this exam. But what I'm not sure is should I concentrate only on the criteria that it mentions for this exam? Or should I be approaching this exam like I need to revise the whole lot like I was not going an "upgrade" exam?

Thanks in advance!

So you have to take the exam within a month of taking the course? What happens if you miss the deadline?

I was just browsing Amazon and I found this...

Sun Certified Developer for Java Web Services Study Guide - McGraw-Hill Osborne

It's not released yet and has a release date (according to Amazon anyway, which doesn't really mean anything!) of 15 Feb 2010

I'm thinking oif taking this exam.

I'm not experienced in Spring and I'm considering taking the Core Spring Training course.

Is this exam easier if you've had lots of experience with Spring or could it be achieved quite easily without lots of experience, with the above course and relevant training materials?

I've just noticed that the SCJWS exams aren't even listed anymore on the Sun training website in the UK and Australia. I would like to do the latest 5.0 exam but looks like they are unavailable for me to do! I realise that there is little (or none) materials available aimed directly at the 5.0 exam.

Anyone know anything about this?

Thanks everybody,

Hi,

I have a problem to solve. I need to filter very large XML documents using XPath. I need to provide a list of xpaths to generate a smaller versions of the documents. for example...

Input:<aaa> <bbb>Hello</bbb> <ccc>123</ccc> </aaa> <zzz> <yyy> <xxx>David</xxx> <vvv>true</vvv> </yyy> </zzz>XPathaaa/bbb zzz/yyyOutput:<aaa> <bbb>Hello</bbb> </aaa> <zzz> <yyy> <xxx>David</xxx> <vvv>true</vvv> </yyy> </zzz>What is a good way to do this using Java APIs?

Thanks!

If you are building yet another web service framework as an open-source/commercial alternative to existing frameworks, or just as a "fun little exercise", by all means feel free to ignore me.

However, if you feel you need to roll your own web service framework out of necessity, as part of a larger project, I'm curious about why existing frameworks don't meet your requirements? I'm not really up to speed on the latest developments of every available webservice framework out there, but I know aleast Apache Axis2 offers asynchronous web service support.

I'd rather not go off topic here. If you read correctly, I said I was developing with A web service framework. Axis2 is the framework. I don't want to go into web services here as the question itself is nothing to do with web services and I didn't want to put anyone off from answering the question if they didn't know Axis2 (or web services)

Hi,

I'm hoping that someone can help me. I'm developing with a webservice framework at the moment which allows me to call a method and pass the request String, along with an object which gets populated with data once the response has returned...

Sender.send(requestString, responseObject)

After calling the above method, the executing thread (Lets call it the MAIN thread) can carry on without waiting.

Sometime, a while after calling the above method I want the MAIN thread to wait and do nothing until this object has been populated. When it has been populated with certain parameters I want to continue execution. (Also, I dont have access to the thread which gets created somewhere within the method above)

Regards,
Eurig

I'd recommend you look at Marc Peabody Design Pattern notes for the exam. This is the only thing I read and it got me through
