Java Developer Exam Questions

I got my JCP certification a while ago and have been debating if it is even worth it to go forth and get the Developer certification. A colleague of mine told me that certification exams for specific technologies are generally good only for contract work, not for full-time employees. He suggested rather than wasting my time and money on exams that I should take night classes and work towards a masters.
So this is really a two part question, first of all do you think it is worth the money and time? Secondly, what kind of project assignment could I expect to get if I sign up for it?

well certification in itself is a buzzword which
might be missing.No one expects a developer with 10 years of
experience to have a developer certification in the
CV. It might actually make the CV look odd /
suspicious. Why have a developer certification in
there if you already have lots of experience?
KajWell I have personally interviewed 10s of developers with 10 years of experience, but actually it turned out that they had 10 * 1year experience. Certifications are just a proff that you have worked on that technology as well. We are not talking about just java certifications. e.g. if I am hiring a java developer with 10 years of java experience who has an oracle certification as well, and I need somebody in the team to have a good understanding of databases it would be beneficial.
Or if the job requires some level of tibco experience, tibco certification would be good to have. Certifications just serve a hint that the applicant has some level of proficiency in the field he has been certified in. A j2ee enterprise architect certification might give one an idea that the applicant is familar with some practices in enterprise architecture. 10 years experience might not guarantee that, plus you might agree a lot of resumes you see these days of mid level developers, claim some kind of architectural exp., thought they might not even know of GoF patterns let alone Enterprise integration patterns. If I have two resumes in front of me with same amount of experience, one with a lot of certifications and the other just experience I would prefer the former, since atleast i know somebody has already done the pre screening for me.
I know what you are talking about, but I always encourage developers to go for certifications and not just java certifications,.
PS. I am not talking about entry level certifications only.

Java Developer Exam.

I'm thinking of taking the Java Developer exam.
People who have done the Java Developer exam, could you please contribute with your help by answering these questions ?
1. How long did you program in Java before taking the exam on ?
2. How long did it take for you to complete the programming task ?
3. Was it more difficult than the Java Programmer exam ?
4. Is it worth to take it ?
5. What was the hardest part of the exam ?
Other comments on the Java Developer exam are welcomed as well.
Cheers

Here is what I would recommend, based on my experience:
* Take the mock exams - the tests at javacertificate.com do a good job of helping you identify your strengths and weaknesses. Dan Chisholm's mock exams are tough, but also good for opening your eyes to some things you might not have thought about.
* Concentrate on your weaknesses (mine were assertions, garbage collections, and threads).
* Practice your butt off writing code. Practice, practice, practice. And DON'T use an IDE. Code with a simple text editor and compile from the command line. The test is going to tax your ability to "compile" in your head and you don't want an IDE doing that work for you.
* Familiarize yourself with the Exam objectives. Know those inside and out, and you'll have no trouble with the test. Don't waste time on non-covered topics (e.g. java.io, java.awt).
* Figure out why you want this certification. It's not going to win you any admirers among the gurus. It's probably not going to get you a job. It doesn't mean you can code your way out of a wet paper bag. It's just the start of your journey in Java.
For me, it was something I wanted to prove to myself - a self-taught, entry-level programmer at the time - I could get. It helped me tremendously in my understanding of basic Java, so I don't regret obtaining the cert one bit. I also realize I have a LONG way to go. So, good luck, study hard, practice, practice, practice, and let us know how you do! If I can be of any help, let me know. :o)

Java Mock Exams

I want to obtain Java mock exam questions. Can anyone help me ?

Go to JavaRanch's mock exam site (http://www.javaranch.com/mock.jsp)
They have an entire section of some really good mock exams. Marcus Green's tests are very good, the site also has a "Rules Roundup" game that tests you on Java rules.
Using the mock exams and Bill Brogden's "Exam Cram" (I understand it is no longer published - publisher went out) I recently achieved my SCJP....

Stupid Java Development Question (JDK? XCode?)

I'm brand new to OS X, so forgive my noobness. I'm still getting used to OS X.
I'm doing this little Java tutorial. It says I need to download an install the Java JDK. As I understand it, Java is already built into OS X and I need to use XCode to create and compile Java programs instead of the JDK....where the heck is XCode?
If anyone knows, I could really use some help. Just finished going through the basics of how to make simple programs in Java but I don't know what to do! Lol. I feel so dumb. I kind of want to call Apple, but I think I'd feel to stupid. I think I have to download XCode? That's what I'm doing now. I had to sign up with the ADC. It's a big file though, 915MB, and it's probably going to take around an hour. I hope someone can tell me if I'm doing the right thing or not before then. I'm guessing I just download this and use this to write Java? How then do I compile? The tutorial is telling me to go to the command prompt and do:
Code:
javac filename.java
to compile the class and then,
Code:
java classname
to execute.
I'm guessing that in OS X I'm going to use the terminal to accomplish this?
Any help would be appreciated. I feel really dumb right now. The tutorial only covers how to do this in Windows and Solaris.

Hi Ralph
I'm doing this little Java tutorial. It says I need
to download an install the Java JDK. As I understand
it, Java is already built into OS X and I need to use
XCode to create and compile Java programs instead of
the JDK....where the heck is XCode?
Go to http://developer.apple.com/ and sign up for a free Apple Developer Connection account. Once you've logged in, go to Downloads and you'll be able to find the latest versions of Xcode and Java. When it comes to downloading Java, take care to choose the version which matches your hardware and version of OS X.
[snip] It's a big file though, 915MB,
and it's probably going to take around an hour. I
hope someone can tell me if I'm doing the right thing
or not before then. I'm guessing I just download this
and use this to write Java? How then do I compile?
Yes - they're big files and you need to persevere with the downloads. Once you've got Xcode and Java installed, you can find some newby tutorials on my web page here:
http://www.cems.uwe.ac.uk/~lrlang/javasoundmusic/index.html
You'll find the links to tutorials near the bottom of the page.
The tutorial is telling me to go to the command
prompt and do:
Code:
javac filename.java
to compile the class and then,
Code:
java classname
to execute.
I'm guessing that in OS X I'm going to use the
terminal to accomplish this?
Yes. This technique works for any Unix system (including OS X), and I used to teach my students to work this way, but I no longer recommend it. As you guessed, you have to type in these commands into the Utilities/Terminal program. However, to be effective you also need to know a number of other Unix commands like "cd" "ls", "pwd" and a few more which you can find in any introductory book on Unix. You also need to use a text editor (such as TextEdit) to create your Java source files and then save them to the hard disk. While this technique will work, you won't get the syntax highlighting and colouring that is offered by the Xcode editor.
Any help would be appreciated. I feel really dumb
right now. The tutorial only covers how to do this
in Windows and Solaris.
I think that if you follow my tutorials you will very quickly get up and running with Java development. I hope you enjoy working with Java as much as I do. You can always come back here if you need more help.

Some basic questions on Java development and NetWeaver CE

Hi there,
Can someone please explain for me:
1. What are the development tools that will help me do Java development in SAP?
2. Can I use non-SAP Java development tools (e.g. WebSphere or Eclipse) to develop custom extensions? Are these equivalent to the functionality provided by CE?
3. Given the options for doing Java development in SAP, are there any situations where I would need to do custom development in ABAP? (Is the Java functionality equivalent to the ABAP functionality?)
4. Is NetWeaver CE only meant for Java development, or can it also be used for ABAP development?
regards,
Eric

Hi
for Java development you can user Eclipse or NWDS , which are both and the same .
And about the ABAP development in CE 7.1 in the developer studio is it not possible .
you are allowed for the java development . And about using Non-SAP java development tools
you can use the tools for java development , may the UI building ..... has to be build when compared to
CE 7.1 developer studio

Java Developer

Hi, I am Java Developer !

1. SUN CERTIFIED DEVELOPER FOR THE JAVA[tm] 2 PLATFORMComprises a programming assignment and a follow-up exam. The assignment requires a significant amount of work (at least a month) and focuses on developing a Swing GUI, a simple database and network connectivity. You also have to document your design and reasons for your choices. Where the Programmer Certification tests your knowledge of the language ("human compiler"), the Developer Cert tests whether you understand how to design and code.
If Swing and network programming (RMI/socket) are your interests, then working through the assignment is valuable and you learn a lot about design techniques and coding. The exam also asks questions on your design and I suspect is meant to prove that you did the work yourself.
2. SUN CERTIFIED WEB COMPONENT DEVELOPER FOR J2EE[tm] PLATFORMExam only, similar in format to the programmer exam. Also like the programmer exam, tests only theory and not practice. Focus is on Servlets and JSP. Requires much less effort than the Developer Cert. Studying for this cert will teach you the fundamentals of Servlets, JSP and the web app deployment descriptor.
I would like to find out which one is useful and valuable?Depends on your interests, Java GUI/network design or Web development.
Also please give me some "Good TIPS, BOOKS,WEB SITES to prepare"http://www.coreservlets.com/

SQL certification for a java developer?

Hello,
Can somone please let me know which dba or sql certification I should get as a java developer? My heart is at application development but I though having a solid knowledge in sql queries or database management would help me in writting a better softwares.
Please let me know.
Thank you.

[3] It is a chance to get a quicker certification exam 'win'
[3] It is a cheaper exam (as it it online available and not 'high stakes' ... ie does not give a certifcation by itself).
.... 1z0-051 is about 2/3 the cost of 1z0-047
But I am willing to accept this is a perhaps a small set of positives; and thier may be no point for many.
I really don't like the fact that anyone wanting an Oracle (Enterprise Edition) SQL certification (without PL/SQL) has to go for SQL OCE. An earlier certification would be better.
I generally like the CIW Database Design Specialist: (Exam 1D0-541) content .....
I would certainly modify my earlier idea of 1z0-047 having as a pre-requisite an earlier SQL exam / certification as a pre-req ....
And would certainly have 1z0-051 or CIW Database Design Specialist: (Exam 1D0-541) on the pre-req list ...
( There are precedents for non-oracle exams/certs being acceptable in lieu of an oracle exam .... eg LPIC-1 for 1z0-402 )
( There is however IMHO no precedent for an OCE exam having another exam as a precedent ).
.... Apologies to original poster .... I may have sidetracked your orginal question with a slight debate.

Exam question - follow-up point

Have now resolved the previous coding problem...many thanks to all who helped and aided my understanding.
as a follow-up question -
is it possible to reference "Sets" as an object in a "Map"
the exam question requires a "Map" to be created referencing a String "studentName" and the collection of books that the "student" has read (see previous coding question - http://forum.java.sun.com/thread.jspa?threadID=5196761)
current code is as follows (the Map studentRecords has previously been referenced as a private instance variable):-
public void createReadingRecords()
String studentName;
Set<String> booksRead = new HashSet<String>();
do
studentName = (OUDialog.request("Please input the student name or * to finish","));
while
(!studentName.equals("*"));
booksRead = this.collectBooksRead();
studentRecords.put(studentName,booksRead);
}

The Set is the "value" of the map, which is stored under a "key", which is the student name. You can use the get(key) method of the map to retrieve the value associated with that key, or you can get a collection of all the values with the values() method.

What url should be given to java developer to call wsdl deployed by XI?

Hi gurus,
I generate a web service by using integration directory, and in the wsdl file there is a parameter "location", which I think can be used by java developer to call the web service. However, they think the form of url should be http://.....?wsdl.
So my question is: where can I get this form of url? Any help will be appreciated.

Hi ,
while generating the wsdl you should give an url in below format
"http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel".
Then u can download the wsdl file and give to ur java developer. this file will be ending with.wsdl and file will contain the endpoint url, where the actual service is.
Again if this is not working and if they really want to download, then u should create UUDI registry in ur server and u shoul publish ur service in that registry. from ther developer can directly download the webservice.
how to configure and publish, u can search in SDN with below topic's
"WebAS : A step by step guide for Configuring UDDI registry on Local Server"
"XI : How To publish WSDL generated from XI to UDDI"

Issue with create user and issue with Java Development tab

I have two issues with EP,
1. When i login with Super Admin user, i am unable to Create any user from User Admin tab. Do i have to change the settings of the Super Admin? or is there any criteria for creating the user?
2. How to assign any user the Java Development tab. Though i login with a super admin user i am unable to see the Java Development role and when tried to assign the role, there were no searches for that Java....

Hi Adi,
by default the super administrater has got all permissions. Thus you should be able to create portal users when using a user assigned to the portal group Administrators.
In order to help you with your first question we need more information. Please describe the malfunction in detail. Have a look into the log files and post related error messages.
Regarding your second question: You will find the java development role in PCD
pcd:portal_content/com.sap.pct/platform_add_ons/com.sap.pct.pdk/Roles/com.sap.pct.pdk.JavaDeveloper.
If not, then you haven't installed the PDK business package in your portal.
Go to service.sap.com, choose downloads and search the package (PDK should do it). Download the package, and deploy on your portal using SDM.
Best regards,
Martin

Oracle database 11g certification for Java developer

Hello,
I'm Java developer, OCPJP 6 ( Oracle Certified Professional, Java Programmer +6+ ) and
I decided to pass exams: 1Z0-051 and 1Z0-052 to get OCA ( Oracle Database +11g+ Administrator Certified Associate ) certificate,
but I need some advice, maybe i should seek other certificate, that would be more valuable for Java developer, than OCA.
Thanks for advice.

The answer of whether a particular certification is valuable depends on you, not the tests themselves. The Oracle Certified Master for example is an extremely prestigious certification, and I have considered seeking it at some point in the future to improve my professional credentials. However, the same certification would have absolutely no value to my wife, because she's a homemaker with no interest or intent of ever working with Oracle.
Using an example a little closer to yours, only reversed --- I work as a DBA and PL/SQL developer. On several occasions I have dabbled with Java, and took a couple of classes when I worked for Oracle. I could code in Java if I had to, but wouldn't really be good without a lot of practice. However, I've never really had a sufficient need in my work to dig in and really practice enough to use it. I considered going for the Oracle Java certifications as a means of kick-starting that and getting to the point where it was really a viable option in my development. Ultimately I decided not to because I've been working with Oracle for better than fifteen years and there has never been an occasion where I really felt a need to know Java. If I were to spend a bunch of time improving my Java skills just for the certification, there's no guarantee I would ever use them after that.
Coming back to you -- if you already need SQL and DBA skills in your work, then those certifications should be of value to you immediately. If you think that you might work (or want to work) more with SQL and DBA-level skills in the future, then they should be of value to you in the future. If you won't use the skills now or ever, then the exams do nothing but add a line to your resume (which still has value, but you must determine how much).

Using CE 7.1 ESR with ABAP based web services requires java development?

Hi All,
When developing a web service in ABAP, what java development must I do to make the web services available in an ESR that is located on CE 7.1?
Thanks,
Regards,
Mel Calucin
Bentley Systems, Inc.

Hi Stefan,
Someone told me that the difference between CE 7.1 ESR and PI 7.1 ESR is that to register the ABAP web service into CE 7.1 ESR you need to create EJBs and that you don't need to do this for PI 7.1 ESR (since ithe PI 7.1 ESR is ABAP based). I didn't think that this was the case so I put this question in this forum to confirm this. I am arguing to put in CE 7.1 because we don't need the PI 7.1 functionality. This someone told me that we are more of an ABAP shop than a Java shop and that we don't want to develop EJBs whenever we develop ABAP based web services.
Thanks.

Mel Calucin
