Hello! The beta exam is coming!
I will post another copy of the revised objectives (they are almost identical to what they were before, except that we've removed a couple of minor things).
There is no book out for this exam, of course, although there is an unsubstantiated rumour that Bert and I and Michael Yuan will be working on one...
But that doesn't help you for the beta... so we'll put together some sample mock exam questions for each section. I'll have *some* of those up this week.
Most of the content is in the MIDP 2.0 specification, the CLDC 1.1 specification (although you are expected to know the major differences between 1.0 and 1.1), the JTWI spec, and a little on WMA and MMAPI. The largest percentage of questions are in the GUI stuff -- low-level/high-level API and also the Game API.
Plenty of questions on deployment, and most importantly-- knowing what is and is not guaranteed by the specs for writing portable applications. Again, there is NOTHING that is device-specific.
cheers, stay tuned,

Dear Kathy, maybe you can help answer this question.
Thank you so much in advance!
Dear Mr. Yuan, it is understandable that there is no book specifically written for SCMAD, but there are other books on J2ME. May I request you to please single out one of the existing books, which will best prepare me for J2ME Beta exam. Since you are one of the creators of the Beta exam I thought that you are in the best position to give your opinion and recommendation.
Thank you very much in advance.

Hi Everyone!
I'm very excited about the new Sum Certified Mobile Application Developer for the Java 2 Platform, Micro Edition, Version 1.0 certification exam.
The FREE beta starts on February 5-25, 2004 and worldwide registration begins on February 4.
To get a free voucher:
Send an email to
Subject Line: SCMAD Voucher
Include your full name, email and prometric id number.
Please allow 5 business days for a response.
This exam does have a prerequisite the Sun Certified Programmer (any version).
The beta is scheduled for 4 hours and will be available worldwide at all Prometric testing centers. There are approximately 160 questions. If you pass the beta exam, you will receive your full certification package (including a lapel pin, ID card, business card logo and the certificate
itself) from Sun upon the formal release of the certification in the spring of 2004. The cost of a certification voucher is normally $150.

Testing Objectives:
Sun Certified Mobile Application Developer for the Java 2 Platform, Micro Edition, Version 1.0

Section 1: JTWI (JSR 185) and Overview / JTWI-compliant Wireless Applications
1.1Identify the goals and characteristics of the JTWI specification (JSR 185), including the mandatory specifications, conditionally required specifications, and the minimum configuration. Compare the relationship and differences between JTWI and other wireless Java technologies.
1.2Develop portable applications that are compatible with the requirements and restrictions an application programmer must adhere to, in order to ensure compatibility with a JTWI-compliant device, including resource minimums (eg. standard-size application), clock resolution, and the use of preferred MIME names as applicable to CLDC 1.0/1.1, MIDP 2.0, WMA 1.1, and MMAPI 1.1).
Section 2: CLDC (1.0 / 1.1)
2.1Identify correct and incorrect statements or examples about the requirements and scope of the CLDC specification, including the differences between 1.0 and 1.1.
2.2Describe the ways in which a CLDC virtual machine does and does not adhere to the Java Language Specification (JLS) and the Java Virtual Machine specification.
2.3Identify correct and incorrect statements or examples about CLDC classes including those derived from J2SE, and the CLDC-specific classes, including identifying which core J2SE classes are NOT included in CLDC, or have different behaviors (example: java.lang.String, io classes, etc.)
2.4Given the differences and limitations of exception/error handling with CLDC devices, handle exceptions correctly.
2.5Wirte code that effectively manages memory / garbage collection.
Section 3: Security (both CLDC and MIDP)
3.1Given a set of requirements, design and build applications given CLDC-specified application-level security, including the sandbox model.
3.2Identify correct and incorrect statements or examples about untrusted MIDlet suites.
3.3Explain trusted MIDlet suite security authorization and permissions, including the process for MIDlet suite signing.
3.4Explain requirements and process of using X.509 PKI authentication for MIDlet suites.

Section 4: Networking
4.1Write code using the Generic Connection framework specified by CLDC, recognizing its characteristics, use, classes, and interfaces. This may include identification of the class hierarchy and relationships of the Generic Connection framework.
4.2Write code for MIDP 2.0 networking, and issues and limitations related to HTTP, HTTPS, and TCP/IP sockets and Datagrams, recognizing which connections are required and which are optional, as well as comparing the issues related to TCP/IP and UDP Datagrams.
4.3Write code using the MIDP 2.0 classes in the package, including code that correctly opens, closes, and uses a network connection, using the implications of network blocking operations, scheme, connection number limitations, and character encoding.
4.4Given a problem scenario, troubleshoot networking issues for MIDP 2.0.
Section 5 -- Application Model /Delivery / Lifecycle / Provisioning
5.1Explain the specification guarantees for: browsing for MIDlet suites, transferring MIDlet suites, using HTTP, push registries, basic authentication, installing and updating MIDlet suites, invoking MIDlet suites, and deleting MIDlet suites.
5.2Identify correct and incorrect statements or examples about the MIDP application model, including: the MIDP execution environment, MIDlet suites, MIDlet suite packaging (including the manifest and the application descriptor), discovering available services on the device, discovering which version of MIDP/CLDC is on the device.
5.3Develop applications that correctly reflect a MIDlet's application lifecycle, including: the purpose of the MIDlet class, communication with the application management software, platform request API, valid MIDlet states and transitions, and the behavior that should and should NOT be implemented within different lifecycle methods (including the constructor).

Hi, you may have answered this before, but how long from Beta exam to real exam?
DOH! You said spring 2004. Now what season would that be around here... winter I guess.
The exam specs sound a bit scary - 4 hours and 160 questions? ( )

Would we know if the beta exams are closed for further entries?

I imagine they'll warn us when that happens.

Hi Guys,
We're going to slide this thread over to the SCMAD forum, see you there!

Spot false dilemmas now, ask me how!
(If you're not on the edge, you're taking up too much room.)
I agree. Here's the link:
subject: SCMAD beta starts Feb 5th.
It's not a secret anymore!
