Sources of the NFC stack for Xperia A2 SO-04F

Greeting to all! Where I could find a sources of the NFC stack parts for the Sony Xperia A2 SO-04F phone? Especially I'm talking about this /system/bin/snfcboot
/system/bin/snfcccserver
/system/lib/libnfc_sony.so
/system/lib/libnfc_sony_jni.so and other parts of the Android NFC stack which was modified by Sony for this phones firmware. All I could find is the kernel driver for the Sony CXD2235AGG NFC/FeLiCa chip which is used in this phone. I need this source codes to enable NFC HCE functionality on this phone. Thanks a lot for your answers! If I've asked in a wrong place, please, give me a right direction where to post this question.

Hi
Open Source Nfc stack can be found in those patches

Re: Update the BT Stack for Windows by Toshiba - Satellite A300-1MS

How do I update the Bluetooth stack for windows by toshiba? Do I have to uninstall the previous one existing on my Satellite A300-1MS or I just install over it?

Hi
Usually you could install it over the old BT stack.
But if you would receive an notification that an old BT stack must be removed firstly, then remove it and then install the new one.
By the way:
This Toshiba BT portal is really useful and helpful. It contains a lot o FAQs which could be interesting for you.

Trying to determine if we need the Java stack for ERP 6.0 upgrade

An issue we have regarding our research of a potential ERP upgrade to 6.0 has to do with the potential requirement to add the Java stack to the WAS engine that support our ERP. This appears significant due to the impact on infrastructure requirements and operational support. Based on the master guide for ERP 6.0, it appears that the following components would require the Java stack or usage type AS-Java:
- Biller Direct 6.0
- Learning Solution LSO (CP) 600
- ESS/MSS -- XSS 6.0
- Extended E-selling Components, XECO 5.0
- Enterprise Portal Content for Business Packages
- XI Content, Elster 2.0
Is this the complete list? Will other components of ERP or ehp's require the Java stack in the future? How likely is it that the Java stack will become a requirement for us to support ERP?
Thanks,
Thomas

Yes, this is correct if Java Stack is already install but I understand from the question that they do not have Java installed already so if they plan to go to ECC 6.0 ABAP Stack they won´t need to install Java stack before or after upgrade.
They only need to do it´s upgrade to Abap stack to ECC 6.0 and in fact if actual 4.7 is non unicode they won´t need to make it unicode before or after either, just when installing ECC 6.0 SR3 then Unicode is the only way to intall it.

Finding which source is the correct one for a compiled class file

I have a compiled class (myclass.class) and 3 source files for it (myclass.java). Is there any method, utility, or software that will let me find which source file is the correct one?
I have about a 100 of these classes which have a lot of copies of the source and we don't know which source is the correct one. The compiled classes are deployed and working and cannot be replaced.
Thank you for your time!

Thank you all for your suggestions but..
1. Recompiling the existing sources and checksum the compiled classes is not a full solution. In addition to finding the version of the compiler that was used and the version of the JDK libraries that were used, I do not know which switches were used when the class was compiled (e.g. -g will output debug info, etc.)
2. Decompiling: I could not find a good enough decompiler I tried jad which failed with some of the classes; I tries JDec which I did not feel I can fully trust the output (format was less accurate than jad). I tried jode which is limited to java 1.3.
3. Versioning: our project now is actually to move all the source to Subversion.
If there is a better decompiler or a way to ensure that a given source file matches the compiled class, please let me know.
Thanks in advance!

HT1923 i cannot find the source of the itunes folder for uninstallation

i was trying to download the new version of itunes but when i try to download it, it says that it wasnt able to find the correct folder for the installation program and i am not unable to uninstall it neither. how else can i reinstall the itunes?

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Any updates on the camera features for Xperia z1?

What is the software stack for Verizon Your Domain Pro?

What operating system and software packages are included in the Verizon Your Domain Pro hosting product? If Linux, is shell access provided?

FYI, you're primarily talking to other customers here.
As you've seen, Verizon doesn't do support by email.
When I call Verizon I try to do it during weekday business hours. That often gets me a helpful representative located in the states. It helps if you get to the retention people by selecting the options to cancel service.
If you have an issue that you think other customers can help with, please post the details.
Good Luck.

How to specify for JVM the stack for ONE specific thread that invokes JNI

Hello all!
I'm 2 days now looking for a solution in several forums but even in Sun Java Forums nobody was able to come up with a solution. If you know a better forum to place it, please let me know.
Description:
I have an application that launches several threads of different types. One of them is quite specific and run a critical JNI C++ process. The remaining ones are just for controling of other stuff... When I call the application by the command line
java -classpath ... -Xss20m -Djava.library.path ... pack.subpack.myApp
the application usually crashes: My computer has 256MB RAM of memory that vanish in seconds and causes an OutOfMemoryException
Sometimes the application works properly, but sometimes the memory usage goes up fast until a general crash.
What I believe that is going on:
When we declare -Xss20m, I undestand that for each thread the JVM will attemp to allocate more 20MB, and if I have 10 threads, it goes up to 200MB and so on; however I'd like to have 20MB just for my critical process (that is called in one specific thread) and not for any thread.
If I try to reduce -Xss parameter to, let's say 10MB, my C++ process overflow the JVM stack for the thread.
So, does any body have know how to solve it? Please... I need experts help!
Thanks a lot,
Calegari

There we go...
I have this class:
package calegari.automata;
* Title: 
* Description: 
* Copyright: Copyright (c) 2003
* Company: 
* @author Aur�lio Calegari
* @version 1.0
public class Native {
* Parameters:
* individuals --> All binary individual (AC rule)
* indivLength --> number of infividuals
* numEval --> number of RIs
* generateUniform --> Uniform distribution of density
* seed --> seed for current generation
public native double[] AutomataIterator(int[][] individuals,
int indvLength,
int numEval,
boolean generateUniform,
long seed
static {
System.loadLibrary("Native");
public Native() {
Then, running
javah -classpath ... calegari.automata.Native
I'll get the following .h
/* DO NOT EDIT THIS FILE - it is machine generated */
#include "jni.h"
/* Header for class calegari_automata_Native */
#ifndef Includedcalegari_automata_Native
#define Includedcalegari_automata_Native
#ifdef __cplusplus
extern "C" {
#endif
* Class: calegari_automata_Native
* Method: AutomataIterator
* Signature: ([[IIIZJ)[D
JNIEXPORT jdoubleArray JNICALL
Java_calegari_automata_Native_AutomataIterator___3_3IIIZJ
(JNIEnv *, jobject, jobjectArray, jint, jint, jboolean, jlong);
#ifdef __cplusplus
#endif
#endif
Next, I built my cpp file which is right bellow
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include "jni.h"
#include "calegari_automata_Native.h"
#include "util.h"
double IndividualEvaluator(long rule[], int automataCells[][149], int numInit1s[],
int numOfACs, int numEvaluations);
char getNext(char simb);
JNIEXPORT jdoubleArray JNICALL
Java_calegari_automata_Native_AutomataIterator___3_3IIIZJ
(JNIEnv *env, jobject jobj, jobjectArray indiv, jint length, jint numEval,
jboolean isUniform, jlong seed)
printf("Native JVM call for C++ critical block: Started \a[-]");
int ACs[10000][149]; //Will be filled with 100000 Initial states of a cellular automata
int numIndiv = length;
int numOfACs = numEval;
//Dencity of each Initial state of cellular automata
int num1sRIs[10000];
//response
double resp[1000];
//set seed
srand((unsigned int) seed);
//generate Cellular automata states
//Uniform generation
if(isUniform)
for(int i=0;i<numEval;i++)
int num1s;
num1s=0;
for(int j=0;j<149;j++)
ACs[i][j] = ((rand()%numEval)<i+1?0:1);
if(ACs[i][j]==1) num1s++;
num1sRIs[i] = num1s;
printf(" %d ",num1s);
else //not uniform generation
for(int i=0;i<numEval;i++)
int num1s;
num1s=0;
for(int j=0;j<149;j++)
ACs[i][j] = rand()%2;
if(ACs[i][j]==1) num1s++;
num1sRIs[i] = num1s;
//load individuals and start the critical method
char simb = '-';
for(int i=0;i<numIndiv;i++)
jintArray oneDim = (jintArray) env->GetObjectArrayElement(indiv, i);
jint *indiv=env->GetIntArrayElements(oneDim, 0);
simb = getNext(simb);
printf("\b\b%c]",simb);
resp[i] = IndividualEvaluator(indiv,ACs,num1sRIs,numOfACs,300);
jdoubleArray retApts;
retApts = env->NewDoubleArray(numIndiv);
env->SetDoubleArrayRegion((jdoubleArray)retApts,(jsize)0,numIndiv,(jdouble *)resp);
printf("\nReturning to Java plataform: Completed\a\a\n");
return retApts;
char getNext(char simb)
if(simb=='-') simb = '\\';
else if(simb=='\\') simb = '|';
else if(simb=='|') simb = '/';
else if(simb=='/') simb = '-';
return simb;
Then it works fine since we declare the size of the stack to JVM, however, if we don't... We get a crash!
Any idea?
Thanks

Do I need to have a JAVA Stack for normal ECC 6.0 ?

Hi together,
we want upgrade our R/3 4.7 to ECC 6.0.
Do I need JAVA deployment on my ERP system as part of the upgrade?
What funktions are in the JAVA Stack for ECC?
best regards,
Carsten Schulz

Just as advise:
I would highly avoid any dual stack installations nowadays. You can install the J2EE engine on the same host but use a different SID so you have two separate instances.

Sony Video Unlimited no HD playback for Xperia Z2

Hello Sony,
When will Sony Xperia Z2 owners be able to watch purchased movies through Sony Video Unlimited in HD on their devices?? Currently HD movies purchased will only play in HD on the Playstation console and SD on mobile devices, I think given that the Xperia Z2 can support huge external storage card sizes that we should be able to be given the HD option, as well as that we have a Full HD screen display.

Excessionist wrote:
As I understand this, this is a limitation in the service, not a technical issue. Usually, content owners do not allow HD playback to mobile devices, even if HD is available from the same service for viewing in your living room.
That is a shame since HD movies bought from the Sony Video Unlimited store would look so nice on the Sony Xperia Z2 Full HD screen as oppose to paying for movies just to have a SD version available for mobile. Hope they are able to provide the HD content for Xperia Mobiles/tablets as I probably like most other Sony fans purchase content from the Sony ecosystem, I seen quite a lot of movies in Google Play that give the option to purchase HD version.

Changing login module stack for Netweaver Portal?

G'day,
I want to change the login stack for Netweaver Portal (at http://<host:50100/irj).
Currently portal is configured in Visual Administrator to use the "ticket" authentication template. I can change this authentication template and change how I authenticate to portal.
But changing "ticket" authentication template also changes how other applications perform authentication. So I changed the login module stack for the "com.sap/irj*irj" component to not use an authentication template, and added my own login modules.
But when I access portal again, the "ticket" authentication is still used. I restarted the cluster to be sure but no matter what login modules I configure for "com.sap/irj*irj", only changes to "ticket" have any effect.
So: how do modify the login module stack for portal, without modifying the "ticket" authentication template?
--Geoff

Hi,
If you'd like to change the authentication stack only for the EP but not for all applications that use UME authentication, then you have to modify the descriptor authschemes.xml. You have to change the scheme "default" to point to another LM stack instead of "ticket" as it is shipped.
Kind regards,
Tsvetomir
