I would be interested in an 'upgrade' exam focused study guide/book as well.

Does anyone know of any documentation that specifically says what is on the upgrade exam and what is not?
Seema,

What are major areas of focus in the SCJP 5.0 compared to the SCJP for 1.4?

Does the test place more emphasis on the new features of 5.0? and if so which ones are the most important to study?

Also does the SJCP 5.0 upgrade exam mainly focus on the new features of java 5.0 or are basic language questions included as well?

Thanks,
Dave

Christian,

I'm curious where you see AJAX going in the next 5 years. Do you see it becoming the ideal view technology for most web apps out there? I think as AJAX becomes more mainstream users will start expecting the 'desktop' type style that AJAX provides and will thus push the business in that direction.

Also do you know if there are any full fledged frameworks in work to facilitate as an AJAX api? I know there are many helpful code sets out there now supporting AJAX functionality, but I would love to see a major player in the web scene (sun, apache, etc.) create a solid core set of APIs that will become the standard.

Thanks,
Dave
I agree that the current version of the exam isn't bound by any version of the J2EE spec, but the requirements are outdated. I would also assume that the questions on the multiple choice are out dated as well and would require you to learn certain aspects of older J2EE spec.

If i'm going to spend ~$400 for a certification it better be the best it can and thus I would want to take the latest and greatest. Anyways they have said in the past that they are working on upgrading it. Who knows maybe after they are finished with the new SCJP 1.5 exam then they'll have a beta for the new SCEA...

There needs to be two separate forums. They are both separate technologies, JSF is bound to overtake Struts as soon as it catches on and like someone else said its becoming a part of the J2EE spec, you can't argue with that.

I'm sure Sun has to have some sort of numbers on record. I bet they know exactly how many people are certified and what their scores were. How else would they know how to target questions in the future

By making the Beta paid,Sun has disheartened me.I was preapring seriously for the Beta,but $49 is too much for me(just for a Beta).In this case, I will wait until the Final exam is released & the give the Real thing.Why waste 4 hrs on a beta?



I agree with this statement. THe point of the beta is help Sun out and for them to make it free to all those that do. You shouldn't have to pay for a product that hasn't been released...

On the other hand I do understand that if you have to pay you will get a better pool of individuals taking the beta. This will in turn give you better results on the exam.

In my opinion the $50 is too much for me to take a beta exam and I like many others will wait for the full version and the new HF book I love those books!!

just my 2 cents.
I agree that this needs to be answered. I know there are alot of us out there waiting for the SCEA update. Maybe we should make a poll to see how many are waiting on the new version. If there are alot then maybe Sun will notice and work faster or at least give us an idea.
I am getting the same error when using logic:redirect. I get the request utils null pointer no matter if i use a global forward or a direct forward to the action itself.

Has anyone figured this out other than changing server versions? Is it api related? Maybe there are some struts dependent libraries that are out of sync with what is expected?

Any help would be great.

Thansk,
Dave

Hello,

Just wanted to let everyone know there is a sweet deal going on where you can get a free ipod if you and 5 friends sign up for one thing throug this site. Generally they are credit cards or some service, but they are really easy to just cancel.

M Kruithof,

How long ago did you sign up for the exam? Was it fairly recently?

One of my biggest concerns is that the exam hasn't been updated to allow for newer versions of j2ee to be used (ejb, etc.) I'm not sure if sun is even planning on putting a version number on it, but I'd be curious to what changes from the current version to the version they are planning on releasing at the end of this year.

Does anyone know what kind of changes the newer version might include?

Thanks,
Dave
Hello,

I've actually been waiting to take the SCEA until after Sun updates the exam, which has been rumored to be happening late this year.

My question is does anyone know if sun has recently updated the description of the second step of the SCEA? Last time I read the description of the assignment part it said you had to use J2EE 1.2. According to the new description you can use any released version.

The assignment requires that you have an in-depth understanding of the Java programming language and J2EE APIs. You can choose to use any released version of the J2EE APIs.

Can anyone confirm that the description has been updated recently?? If so, do you know when? I'm just trying to guess at the possible date for the updated version of the exam.

Thanks,
Dave

Hi,

I agree with that answer. XSLT is just a way to transform and display xml without parsing through the xml and converting it to some other presentation format. XSL/XSLT is recognized by the browser and is therefore rendered on the fly, requiring no compilation, and thus no processing code to transform the xml into some other format.

Regards,
Dave
Dmitry,

Thanks for your reply, it really helped me understand why xml is so important. It just adds another lay of abstraction and lets the presenation layer decide upon how the data should be displayed and with what technology. Which is cool, since you could start with jsp's and then switch to some other presentation technology.

I did have some concern in regards to the performance question that was asked. I'm not so sure that building xml documents within java is such a fast task, especially if you have alot of data to transfer during a request within a web application. What if the xml document ends up have 1,000 nodes? Wouldn't this be a huge bottleneck within the transformation logic and the end result (the xml)?

I would think that building an xml document using DOM would take at least a few seconds for 1000 nodes, and that's way to long for a user to wait on a page to load.

What do you think?

Regards,
Dave
Hank,

If you prefer using a GUI to build your pages, go ahead and use dreamweaver to build the html and then insert your <xsl:???> tags to display your xml.

Check out W3C's tutorial on xslt for any future info : http://www.w3schools.com/xsl/default.asp

Dave
