Regarding CLDC Hotspot

Hi,
i am Mukesh From India Bangalore. can any one help me in setting the cldc hotspot implemation ? i mean what are all things required to setup the development enviorment,i have gone through the white papers but it is not clear how to set up.
secondly i am working on J2ME Application using wtk2.3 beta version, i would like to enable & disable JIT(Just in time) Compiler.
and last query is: How can i do make my methods as inline ? (Wait before you answer this question) i have already tried my hands with static, final, private, making local variables, but no use @ all.
-Waiting for you quick response.

{color:#000080}Your question is not at all clear, but if you're looking for an IDE for j2me you could try NetBeans, a free product from Sun, with the Mobility pack and WTK 2.5.1 (or latest).{color}
i have already tried my hands with static, final, private, making local variables{color:#000080}Doesn't make sense to try stuff without understanding. Programming is not a lottery. I suggest you go through some Java tutorials, such as those available at

Porting CLDC Hotspot VM

Hello,
I want to port CLDC Hostspot VM to an OS running on ARM9 processor.
Where can I download CLDC Hotspot VM source code ?
Thanks In Advance,
Regards
Surendra

If you don't get a definitive answer here, you might try asking on the hotspot-dev (at) openjdk.java.net mailing list. That's where all the HotSpot developers hang out. I know there are people there working on an ARM9 port, though I don't know if it's for the full Standard Edition or CLDC.

InPlace execution in CLDC hotspot implementation

I am working on Inplace execution feature given by SUN in CLDC Hot spot Implementaion. I want to know how much performance can be increased by using inplace execution for the midlet to be run on the device. I have converted the midlet jar file into application image (bun) but not able to know whether I have got any significant improvement or not.
Can anybody tell me that how can inplace execution improve the performance and it will affect which part? Is there any way to know how much performance has been increased like some benchmark midlet for InPlace Execution feature.
Please provide some help.

This type of emulation is called HLE, there are some drawbacks to this approch. The one that i think prevented implementors of an VM to go this road is that it's verry hard to compile all bytecode to native code and be sure there are no security problems. Also the general protection failts will come to your java code! Of cause this can be prevented by putting in a lot of overhead code for every bytecode instruction, but then it's not fast anymore! ;o)

ALV + HOTSPOT + DOWNLOAD ALV O/P to a file Querry ??

Hi All
I have the following requirement in my SAP-ABAP prog which is as under:
>>Hotspot click to be provided on EBELN field then call ME23 tcode skipping the first screen.
>>Hotspot click to be provided on VBELN field then call VF03 tcode skipping the first screen.
>>If check box marked save the data displayed on the report as a file to a presentation server
>> and please let me the Field catalogue table name which exists in dic
As such ther's no inconsistency in my prog. But when i execute my prog , the ALV O/p shows no data .
And regarding the Hotspot click , if you are telling me to use SET parameter Id statement , thn plz specify how to use it.
i mean in the statement
e.g
SET PARAMETER ID 'EBE' FIELD ACC_TAB-EBELN.
when i double click on EBE , it does not allows me to specify EBE as parameter for field EBELN.
I can provide you with the prog which i have made , if needed.
So do help. Helpful entries will be rewarded.
Thanks

What is the Best UK Hotspot Provider for using with the ipod Touch ?

Just ordered my new ipod touch and can't wait to start using it. I just wondered whether anybody here in the UK had done any research regarding what Hotspot Provider to sign up with? I know there is the BT Openzone option or possibly a new company called 'The Cloud' that looks OK ... then there is the 'pay as you go' option or monthly contract choice to make? I know my ultimate choice might depend on what usuage I want or where I am most likely to want wifi? But any comments, observations or user experiences would be welcome.
Thanks.
Jon.

The Cloud have an account specifically for iPod Touch users. I haven't set anything up on mine as I use my mobile for surfing when out and about - but I do check to see if there's free wi fi available before I use the mobile.

+The 1.1.3 release of CLDC HotSpot Implementation included limited VFP support. This feature was supported only when running in interpreted mode. In this release, full vector floating point support is provided when the virtual machine is running in compiled mode.+

+Adaptive compiler - Applications are launched using a standard interpreter, but the code is then analyzed as it runs to detect performance bottlenecks, or "hot spots". The Java HotSpot VMs compile those performance-critical portions of the code for a boost in performance, while avoiding unnecessary compilation of seldom-used code (most of the program). The Java HotSpot VMs also usesthe adaptive compiler to decide, on the fly, how best to optimize compiled code with techniques such as in-lining. The runtime analysis performed by the compiler allows it to eliminate guesswork in determining which optimizations will yield the largest performance benefit.+
[_CLDC HotSpot Implementation Architecture Guide Chapter 4_|http://java.sun.com/javame/reference/docs/cldc-hi-2.0-web/doc/architecture/html/DynamicCompiler.html]
+Two different compilers are contained in the CLDC HotSpot Implementation virtual machine: an adaptive, just-in-time (JIT) compiler and an ahead-of-time compiler. The JIT compiler is an adaptive compiler, because it uses data gathered at runtime to decide which methods to compile. Only the methods that execute most frequently are compiled. The other methods are interpreted by the virtual machine.+
[_Java Tuning White Paper_|http://java.sun.com/performance/reference/whitepapers/tuning.html]
+One of the reasons that it's challenging to measure Java performance is that it changes over time. At startup, the JVM typically spends some time "warming up". Depending on the JVM implementation, it may spend some time in interpreted mode while it is profiled to find the 'hot' methods. When a method gets sufficiently hot, it may be compiled and optimized into native code.+
[_Frequently Asked Questions About the Java HotSpot VM_|http://java.sun.com/docs/hotspot/HotSpotFAQ.html]
+Remember how HotSpot works. It starts by running your program with an interpreter. When it discovers that some method is "hot" -- that is, executed a lot, either because it is called a lot or because it contains loops that loop a lot -- it sends that method off to be compiled. After that one of two things will happen, either the next time the method is called the compiled version will be invoked (instead of the interpreted version) or the currently long running loop will be replaced, while still running, with the compiled method. The latter is known as "on stack replacement", or OSR.+

[_Introduction to scripting in Java, Part 1_|http://www.javaworld.com/javaworld/jw-07-2007/jw-07-awscripting1.html?page=2]
+Many of today's interpreted languages are not interpreted purely. Rather, they use a hybrid compiler-interpreter approach, as shown in Figure 1.3.+
+In this model, the source code is first compiled to some intermediate code (such as Java bytecode), which is then interpreted. This intermediate code is usually designed to be very compact (it has been compressed and optimized). Also, this language is not tied to any specific machine. It is designed for some kind of virtual machine, which could be implemented in software. Basically, the virtual machine represents some kind of processor, whereas this intermediate code (bytecode) could be seen as a machine language for this processor.+
+This hybrid approach is a compromise between pure interpreted and compiled languages, due to the following characteristics:+
Because the bytecode is optimized and compact, interpreting overhead is minimized compared with purely interpreted languages.
The platform independence of interpreted languages is inherited from purely interpreted languages because the intermediate code could be executed on any host with a suitable virtual machine.
Lately, just-in-time compiler technology has been introduced, which allows developers to compile bytecode to machine-specific code to gain performance similar to compiled languages. I mention this technology throughout the book, where applicable.
[_Compiled versus interpreted languages_|http://publib.boulder.ibm.com/infocenter/zoslnctr/v1r7/index.jsp?topic=/com.ibm.zappldev.doc/zappldev_85.html]
Assembler, COBOL, PL/I, C/C++ are all translated by running the source code through a compiler. This results in very efficient code that can be executed any number of times. The overhead for the translation is incurred just once, when the source is compiled; thereafter, it need only be loaded and executed.
Interpreted languages, in contrast, must be parsed, interpreted, and executed each time the program is run, thereby greatly adding to the cost of running the program. For this reason, interpreted programs are usually less efficient than compiled programs.
+Some programming languages, such as REXX and Java, can be either interpreted or compiled.+

+Two different compilers are contained in the CLDC HotSpot Implementation virtual machine: an adaptive, just-in-time (JIT) compiler and an ahead-of-time compiler. The JIT compiler is an adaptive compiler, because it uses data gathered at runtime to decide which methods to compile. Only the methods that execute most frequently are compiled. The other methods are interpreted by the virtual machine.+

+One of the reasons that it's challenging to measure Java performance is that it changes over time. At startup, the JVM typically spends some time "warming up". Depending on the JVM implementation, it may spend some time in interpreted mode while it is profiled to find the 'hot' methods. When a method gets sufficiently hot, it may be compiled and optimized into native code.+
[_Frequently Asked Questions About the Java HotSpot VM_|http://java.sun.com/docs/hotspot/HotSpotFAQ.html]
+Remember how HotSpot works. It starts by running your program with an interpreter. When it discovers that some method is "hot" -- that is, executed a lot, either because it is called a lot or because it contains loops that loop a lot -- it sends that method off to be compiled. After that one of two things will happen, either the next time the method is called the compiled version will be invoked (instead of the interpreted version) or the currently long running loop will be replaced, while still running, with the compiled method. The latter is known as "on stack replacement", or OSR.+

Assembler, COBOL, PL/I, C/C++ are all translated by running the source code through a compiler. This results in very efficient code that can be executed any number of times. The overhead for the translation is incurred just once, when the source is compiled; thereafter, it need only be loaded and executed.
Interpreted languages, in contrast, must be parsed, interpreted, and executed each time the program is run, thereby greatly adding to the cost of running the program. For this reason, interpreted programs are usually less efficient than compiled programs.

Actually, Java is a compiled/interpreted language. See the links below. This is the best classification for the Java language, in my opinion.

why this ; after the condition?
and why do you put else + condition? Maybe you want to put else if?
try this:
if (a.length() == 1) { // I always open and close { } to make my code more readable and avoid errors
a = "0" + a;

RADIO APPLICATION compatible with on BB (BES)

Dear,
Regarding : RADIO APP (to listen to FM radio stations) compatible with on BB (BES)
I would like to download and make use of a compatible RADIO (to listen to the radio) application on BlackBerry curve that is compatible with BlackBerry Enterprise Service I use (BES).
unfortunaltely TUNEIN Radio aapp is not compatible with BlackBerry Enterprise Service I use (BES) used in the company.
What Radio app can you advise to simply listen to FM radio stations.
Thank you for your advice.
Best regards,
JM

Hello bropamda304
Welcome to BlackBerry Support Forums
FM Radios are available on a limited Curve model even Bold and Toruch Models don't have that , I believe 9380 don't have any FM Radios as per this official page http://worldwide.blackberry.com/blackberrycurve/9380/curve_specifications.jsp and this website http://www.gsmarena.com/blackberry_curve_9380-4331.php .
Again , regarding Mobile Hotspot feature , This feasture depends on your Carrier and the service plan you have . If your Carrier supports Mobile Hotspot and you have the required plan then you'll see the same under Manage Connection . If you're not getting this feature then it is not something which you can Install from app world But you should call your Carrier Digicel to know further . You can also refer to this below KB Article :

Is java a compiled language - part 2

yamm_v6.6_6 said
Again, I think you are confusing the compilation process and the interpretation process with the meaning of "compiled language" and "interpreted language", mr. jschell. Compilation process and interpretation process have definitions very well established in the Computer Science, as you said, and I agree with you. There are no controversies in those definitions. On the other hand, the meaning of "compiled language" and "interpreted language" might vary, because in this case there are controversiesNo.
Compilers are one of the most well studied and well defined aspects of computer science more so than any other part of computer science.
And the Dragon book is now, and has been for at least 20 years, the recognized authoratative source of that part of computer science.
And there is nothing in there that supports your conclusion nor nothing that supports your term definitions.
A language in of itself is never compiled nor interpreted. That book specifically defines the process under which a language must be processed to become either compiled and/or interpreted.
If you wish to disagree with that then state something from that book or first demonstrate that that book is no longer the authorative source.
Finally note that in terms of computer science none of the java documents (specifications or otherwise) are suitable authoratative sources. The java specifications although adequate are far from precise in the adherence to definitions in computer science, or even in the definition of java itself.

Wow! I was just googling, and then look at what I found! This thread! Thanks, mr jschell, for your replies. I really appreciate them.

IPhone4 and WIFI Access

I understand you can use your iPhone4 to connect your laptop to the internet.....is this true and if so how does it work? My Verizon Access Manager just ask for my cell phone number to do this but don't really understand it.
Thanks

Thank you all for the great input!
I have included some additional information regarding the Hotspot feature for the iPhone 4 for your convenience.
The iPhone 4 is capable of acting as a mobile Hotspot to share its data connection with up to five devices at once over Wi-Fi. It can also function as a modem via USB or Bluetooth. This capability is called Personal Hotspot on the device. See pricing below:
$20.00 monthly recurring charge.
2 GB monthly data allowance applies to all data transmitted (on handset and shared devices) while the mobile Hotspot application is active.
$20 / 1 GB Overage Rate.
This is in addition to the iPhone Data Plan.
Detailed set up instructions for the Hotspot on the iPhone 4 can be found at the link below:

Wifi gone slow on ios devices connected to AEx

I have the current gen airport express which is using both 5ghz and 2.4ghz. i have a mbp mid 2010, ipad mini and iphone 5 connected to it. i assume all the three devices are capable of 5ghz networking. my AE connects to my ISP via pppoe.
i am on a 10 mbps line and i get a full 10 mbps (1.2mBps) on my macbook pro. for some reason iso devices are experiencing a terrible slow down. even the apple tv 3rd gen is experiencing lags. i barely get about 400kbps (50kBps) of speed from the ios devices. this is when there is no active download running on the macbook. i got this app from the mac app store called systempal and it doesn't indicate any activity on the mac.
to confirm if this has nothing to do with the "speed test" app on the devices, i ran the test from different speed testing apps. all reported same results. and the speed test app on an android device on my network reported full download speed!
also, when transfering some movie files to my ipad over wifi from my mac via itunes, the speed was terribly slow. it took about 20 minutes to transfer a 900 mb movie to my app via itunes file sharing.
i have done the usualy troubleshooting like rebooting the devices and the router, resetting the network settings on my devices and resetting the router, etc.
no go!
can someone help please?

Hi JBelcher!
Thanks for troubleshooting your device with Samsung regarding the hotspot and iOS devices. I see that you mentioned you have no problem with Android or Windows devices, and the only issue is with Apple devices.
Have you tried the hotspot in different areas with the iOS devices? Please do so and check the speeds in different areas.
Please also complete a master reset on the Charge and let us know how this works for you. Here's a link on the master reset. http://bit.ly/w21WpW

Received mysteries text regarding a code send from my own Iphone after using a unprotected public Wifi-hotspot

Today I received a text from my own Iphone number displayed as +28 18 xx xx that I have not written myself. It said I now had a new code thas was xxxx without specifying what for. Just before I got that text I had used a couple of different public wifi-hotspots. Should i be worried? After i searched Google all I could find was that it was a possibility your Iphone can be hacked on Wifi and the other option was that the code I received maybe was from the Verified SecureCode by Visa & Mastercard that I did sign up for a long time ago. If that was the case someone would be trying to use my credit card. If anyone could help me to disclose why i got the text from my own Iphone I would be very grateful.

EXCEPTION_ACCESS_VIOLATION issue with regard to OpenGL

EXCEPTION_ACCESS_VIOLATION issue with OpenGL occurring with the Java SE Runtime Environment 6u17 on Windows 7, 32 & 64 bit platforms.   Version 6u24 and later does not produce the crash. However, we cannot use any other version of JRE other than 6u17 due to customer constraints. The two primary scenarios where crash (jvm exits) occurs are: 1) toggling between two applications then selecting an image item on screen ( OpenGL rendering takes place)... (Log file: hs_err_pid6568_C2_TC_error.log). Scenario 2: When panning an image (OpenGL rendering takes place) and then clicking a button to load additional image data (OpenGL rendering takes place), crash occurs (Log file: hs_err_pid6036_ENR_TERRAIN_crash.log)
Is there any Oracle documentation noting any JRE fixes between 6u17 and 6u24 that might at least mitigate the issue(s) described above? Or information with regard to issues between JRE's and OpenGL ? Also, if anyone can advise on code mods, etc that we can try toward said mitigation efforts of course would be helpful.
The following snippet hopefully should suffice as general example for both noted issues:

There are some other solutions possible.
1. Get another driver. The only one known is java only so it wont crash. But is not not free.
2. Use a proxy driver. That means that another app actually does the database work. If it crashes you just start it again (which you can do in your main code.) That way it won't take down your server. There are commercial jdbc drivers that claim MS Access but are are really just proxy implementations as an option in this area.
