No More Java Support In Windows XP
This Has to Be debated...
Sorry, I don't agree that Sun screwed itself by not letting Microsoft embrace, extend, and exterminate Java. The Java lawsuit against Microsoft is yet another example of how the culture at Microsoft makes it almost impossible for them to deal with other companies in a fair and honest way.
Microsoft saw Java and got scared (rightfully so). So they attempted to modify it in such a way that it would become yet another language that only worked on a Microsoft OS.
Now imagine this scenario: What if Microsoft had truely embraced Java technology? What if they made J++ the best, fastest, most compliant IDE on the planet? What if they made IE the best, fastest, and most complient Java enabled browser on the planet? Then people would flock to their products becaue they would be the best in the market.
I hate to use such easy descriptions as "good" and "evil" but this is a perfect example of how the culture at Microsoft made it impossible for them to relate to Sun and Java in a "good" way that could have benefitted both companies. By extending the Java API and not supporting other portions of the API they set in motion a series of events that doesn't benefit the consumer at all.
Unfortunatly, Microsoft refers to this process as "inovation".

Hello All
I do no know if this is the right place to post this topic, but does anyone know of an api that provides usb support for windows. I was looking a jusb, but the documentation says it only has support for linux. So far the best I have found is Mr Stahl's thesis which provides very limited support for windows. I was wondering if there was anything more stable (free or not)
ThanksHi,
Im trying to connect 2 computers using USB or Parallell port. On one computer I want to install a printer (regular windows printer) that prints through either USB or the Parallell port. On the other computer I want to listen on the Parallell port/USB port and receive the input and write it to a file.
Does anyone have a some sample code to do this? I've tried the following code (rxtx) but it cant find more than 2 ports (one parallel and one serial - no USBs even though I have 5 USB ports). Since I could only find the USB I tried to listen on the Parallell port. Problem is that I dont receive any data.
<---THE CODE--->
Enumeration port_list = gnu.io.CommPortIdentifier.getPortIdentifiers();
while (port_list.hasMoreElements ()) {
CommPortIdentifier port_id = (CommPortIdentifier)port_list.nextElement ();
if(port_id.getPortType () == CommPortIdentifier.PORT_PARALLEL) {
System.out.println("Found port "+port_id.getName()+ "id "+port_id);
CommPort commPort = port_id.open("",2000);
InputStream is = commPort.getInputStream();
byte buffert[]=new byte[1024];
int len;
System.out.println(">>>>>>>>len "+is.read(buffert));
while((len=is.read(buffert))==-1)
Thread.sleep(500);
is = commPort.getInputStream();
System.out.println(">>>>>>>>len "+len);

Java installer in Windows Vista: error 1721
Hi,
I cant install java SE in Windows Vista. I get always this error:
error 1721. There is a probleme with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.
Anyone knows how I can solve it? I tryed with other java versions but I get the same error.
Thanks in advance.If all else fails, your Vista could just be screwy.
If you're willing to go that far, and you've exhausted all other options, you could try reformatting and reinstalling Vista. (Or even XP, since it's way more stable. :D)
At any rate, this doesn't seem to be the file's problem, as plenty of people have gotten it working.
Have you installed any ... "distasteful" software on your computer, or tweaked stuff like a hardcore techie? Because it's quite easy to screw with Windows. :) -
How do i monitor performance in the system of a Java program in Windows XP?
I want to record the CPU usage and Memory usage on an hourly basis programatically, for an already running java class in Windows XP environment for the purpose of testing the Java class. The recording has to be done independent of the java class.By Cpu usage and Memory usage , i need to know how much of the computer's memory and CPU has been used by the java class.
I tried the HPROF tool available with J2SE 5.0, but it gives the details of each of the functions' usage in the program's allocated space in memory. moreover, it is not independent of the execution of the class.
The other option is to make use of the Performance tool available in Windows Xp->Administrative tools. This is a complex procedure, and i am not sure of how to proceed in this direction.You can use the windows performance monitor (perfmon.exe / perfmon.msc). I don't know wther it is also included in the XP Home Edition. But this is the tool you are looking for. It can display the information in realtime but also can write to a protocoll.
Here's a shor description of what to do (i have a german windows so i'm more or less guessing the english terms)
- Start perfmon.msc
- In the tree on the you can see "systemonitor" (the realtime display) and "performance protocolls and warnings"
- open "performance protocalls and warnings", the first sub element should be something like"performance protocalls" or "performance indicator"
- open the context menu for it and create a new protocoll settings.
- add the information to it you are interested in and make other changes if you want
- start the new configuration
once you have the information you can display it it in the systemmonitor by selecting "display information from protocal" from the toolbar
It will take some time till you know what you are doing (and most of the information the performance monitor is useless to 99% of the people). But its a quite usfull tool once you know how to use it -
RSPOR_SETUP = Different ABAP and Java support packages.
Hi all,
We have an ECC 6.0 system with abap+java stacks. When we run the RSPOR_SETUP report we get this error:
Different ABAP and Java support packages. Combination of support packages invalid
And with some more clicking we find this:
6. Compare version information of Java support package (com.sap.ip.bi classes) with ABAP support package (SAP BI)
ABAP Support Package: 13
Java Support Package: 0
On the Java stack we see (among others) these components:
sap.com BI-IBC 7.00 SP12 (1000.7.00.12.0.20070509050058)
sap.com BI_MMR 7.00 SP12 (1000.7.00.12.0.20070507084106)
sap.com BI_UDI 7.00 SP12 (1000.7.00.12.0.20070507084125)
sap.com BI-BASE-S 7.00 SP12 (1000.7.00.12.11.20080324092518)
sap.com BI-WDALV 7.00 SP12 (1000.7.00.12.1.20071105133039)
sap.com BI-REPPLAN 7.00 SP12 (1000.7.00.12.3.20080104101916)
So I believe all components are correctly installed.
What are we doing wrong?Hello.
Please be aware, that report RSPOR_SETUP should NOT be used with a Netweaver 04s system. This report has been replaced by the support desk tool. I request you to run the support desk tool as per note 937697 to check if there are any configuration issues in your system.You can resolve any red traffic lights that might be reported by the tool by following the corresponding actions suggested.
I hope I can be helpful.
Thanks,

Need to communicate c server on linux & java client on windows
Hi!! I am new to socket programing in both C and Java.
From let I downloaded some client server example for c and java and tried that to link !! (I allways learn this way , and I need to do that little urget )
though cient server in linux is working perfectly fine and same for java. But problem is when I tried to communicate C server on linux and java client on windows, I end up with getting some junk characters. Though they are connected successfully.
Here goes code for java client:

System.out.println("Connected to localhost in port 2004");
//2. get Input and Output streams
out = new ObjectOutputStream(requestSocket.getOutputStream());
out.flush();
in = new ObjectInputStream(requestSocket.getInputStream());
System.out.println("above do");
//3: Communicating with the server
do{
try{
System.out.println("in do");

hii!! just trying to make it a little more explinatory
1) what I am trying to accomplish by the above code is: - just need to echo/print from the Server , message send by the Client. I know code is not that good but should be able to perform this basic operation( according to me ).You are wrong. I told you that it won't work as long as you are using ObjectOutputStream and ObjectInputStream. You shouldn't write objects.
2) Message sent by the client is "hello world"(hard coded).No, it's not. You are writing a serialized byte array.
3) what I am getting at the client end is "*message recieved: ur*" (before that It shows the Ip of client machine)
It should print "hello world ".See above.
You are having a problem, and I have told you what the problem is.hey I dont know what went wrong but . I posted all this just next to my first post ...before you posted !!
And hard coded byte array includes "hello world"...may be I am not able to explain properly. -
Are Crystal 9 and Crystal 10 supported with Windows 7?
I have Crystal 9 installed for Peoplesoft report development and Crystal 10 installed for Kronos report development. We are moving to Windows 7 and I am doing testing of all our applications and third party tools now. What I am finding is that both versions will install without error but I cannot connect the ODBC DataDirect drivers and no other drivers will work. So If I cannot connect to our Oracle database then I am wondering if these version are in fact supported on Windows 7? Can someone please respond/explain?
Hello,
Both versions of Crystal Reports are not supported on Windows 7. But I believe Peoplesoft have their own ODBC driver so you'll have to check with them if they support those versions. Our original DataDirect driver would not be supported on Windows 7.
And I don't believe the current 5.3 version are supported in CR 9 and 10.
PeopleSoft should be able to confirm if their OEM build of CR 9 and 10 are supported or even tested on that OS.
Should also mention only version is CR 2008 Service Pack 2, CR XI R2 SP6 is also but it's end of escalation life cycle now, meaning no more patches will be created.
Thank you
Don

ECC 6.0 and Sol Man 7.0 support on Windows Server 32 bit OS
Dear Experts,
I have read that SAP is moving towards 64 bit implementation.
I have to install ECC 6.0 and Solution Manager 7.0 on a Windows Server. We have yet to purchase the hardware and to decide the hardware config I need answers to the following.
Is ECC 6.0 and Solution Manager 7.0 supported on Windows 2003 server 32 bit OS?
Should I buy 64 bit hardware for both or should I go for 32 bit hardware?
Thanks and Regards,
Shailendra> No Need to buy 64bit hardware.
You're aware that successor releases are only available on 64bit? And also the fact, that certain functionality may not work in Solution Manager (e. g. activation of BI cubes etc.)? If he wants to go for EHP4 on ERP he needs to install EHP3 first and then EHP4 using SAINT - which needs a lot of downtime.
SAP recommends using only 64bit system and I can just HIGHLY support that:
Note 931024 - FAQ: 64-bit platforms for Windows
<...>
As of basis release 6.20 productive use of 32-bit platforms is not recommended.
<...>
and
Note 1280759 - SAP recommends only 64-Bit Windows for SAP Appl. Servers
<...>
Therefore, we recommend that you only use 64-bit for your SAP system. Use Windows 64-bit also on small test and demo systems to become familiar with it. Otherwise you will end up wasting a lot of time and money optimizing your ABAP or Java application servers to run on 32-bit.
<...>
Almost all servers produced in the last two years are 64bit capable - so I'd check if the server really doesn't support a 64bit OS.

How java support multiple inheritance by the use of interface.
As per my understanding, Interface is just having the signatures of the methods not the implementation.
So How java support multiple inheritance by the use of interface?
Answer 1: we can institate interface reference by its implemented
class.
����� interface inf...
����� class aa implements inf..
����� class bb implements inf....
Now, inf i = new aa();
inf i = new bb();
Answer 2: We can extends as many interface as we want in the
single
interface.
i.e. interface infFirst....
interface infSecond....
interface infThird....
Now ,
interface ingMulti extends infFrist, infThird...
By above two answers its not prity clear as per the multiple inheritance in C or C++.
i.e.
class first{
method abc();....}
class second{
method bbc()......}
class multi::first::second{
we can call to abc();.....as well as bbc();
-Please give your important suggstion on the same.(Hope I explain it well.)
-JeffThe keyword implement is used only for interfaces not
for abstract class. If i am wrong correct me.I believe your right, but I will double check.
As for the multiple inheritence think about the following code:
class Animal {
// Animal generic stuff in this class
interface Eat {
// Generic stuff that models eating behavior
interface Runs {
// generic methods that model running behavior
public class Horse extends Animal implements Eat, Runs {
// Stuff specific to a horse
}The Animal class is generic but has stuff in it common to all animals.
The Eat interface models behavior that is generic to eating, all living things have to eat something to survive. Herbavore are different from carnivores.
The Runs interface models generic behavior to running, such as speed. A cheeta definately runs faster than a human.
This brings us to the Horse class. It extends the Animal class because it "is-a" animal, and it implements the eat and runs interface because they are behaviors a horse has.
I hope that helps.
Extending an abstract class is the same as extending a regular class with the exception you MUST override all abstract methods in the abstract class. Thats not too difficult but I believe when designing classes, designing an abstract can be more diffecult than modeling the base class, and generic behaviors in interfaces. JMO.

Adobe AIR support for Windows RT and USB
We want to develop an cross platform application. We found that Adobe AIR supports cross platform development for Windows, iOS and Android.
We wanted to know wheather
1) reading and writing to USB port is possible with Adobe AIR?
2) Adobe AIR has support for Windows RT development?
Thanks in advance.I wrote before about my concerns with Adobe AIR, but here is a short summary:
- no road map and no clear plans for the platform,
- support of new devices is often late, Intel chipsets are not supported on Android,
- debugging on a device is a pain,
- inadequate build times for iOS, app package is quite large,
- list of mobile UI components is very limited and UI experience is far from native,
- native extensions are a possibility but still far from perfect (imagine using three very different development platforms all in one app), no debugging,
- performance is not good if you use a lot of Spark components in your app,
- Flash Builder is pretty bad as the development environment,
- ActionScript3 is a poor, outdated language that encourages bad coding practices.
I ruled out HTML5 frameworks for the same reason as you stated above. Last few months I've been working with Xamarin MonoTouch and I think it is perfect for my projects. 100% native UI experience, about 80% of the code is shared among the platforms, iOS, MacOSX, Android and Windows 8/RT are supported. Took me about 2 months to convert my 2Mb ActionScript Adobe AIR project to Xamarin MonoTouch (iOS). The entire process was fun and painless. Now thinking to port to MacOSX and Android. My iOS app is already at the App Store, no major complains so far.
On a down side, Xamarin is expensive for an indie developer with low revenues. You need to pay $300 per year per each platform (iOS, Android, Mac). Plus, you need to develop UI layer separately for each platform, so only part of the code is shared. But I decided it is a way to go for my projects and it's been a very positive experience so far.
As for my professional development, Xamarin offers quite a bit more as well. I get to work with C#, .NET, iOS SDK, Android SDK all in one platform. With Adobe tools you only get to know ActionScript and Flex/Spark framework. Very rarely I see that as a desired qualification. It is like a trap. Your boss tells you to develop a few projects with Adobe tools, it sucks you in for a few years and suddenly you realize that your market value declined dramatically and there is no easy way out of this mess. -

http://e-docs.bea.com/platform/suppconfigs/configs81/winsvr2003_em64t/81sp4.html
Henrik Stahl
Product ManagerHello,
I ran into the same problem searching for the 1.4.2 JDK for Windows x64 platform and found this discussion post. It was helpful!
Could you tell me where to download the JCE policy files from? Do they need to match the same JDK version (1.4.2)?
The Install Guide for SAP NetWeaver 7.0 SR3 Java on Windows MS SQL Server says to download the JCE policy files for your platform (Windows x64) from http://java.sun.com/javase/downloads. But I could only find jce_policy-6.zip. Is that the right JCE policy files for Windows 2003 x64 64bit platform for SUN JSE 1.4.2 64bit?
Thanks,

Developing Java application for windows CE based Handheld device
Hi everybody,
I am planning to develop the java application for windows CE
based handheld device.I came to know that Oracle 9iLite supports
the Developement of Java Application for windows CE devices.Can
i use the JDeveloper IDE to develop the application on windows
NT.If so how to deploy the application on windows CE device(Is
there any options in Jdeveloper to deploy the application).Any
body please give the solution.
Regards,
Siva mani kumar.DI agree. In my opinion Sun has done a horrible job documenting all this madness for the average developer just starting out with this stuff. There is the CLDC, J2ME, Personal Java, J2ME-WTK, MIDP, MIDP-FCS ... maddness. Anyway after sorting through it all for a few days, I think the answer to your question you will need to use Personal Java for WinCE and the Sharp Zaurus, and MIDP for PalmOS for the palm. Jeode seems to be the most common and best Personal Java implementation and it is basically the JDK1.2.2 (or is it 1.1.8) that is designed to run on WinCE and Embeddix (such as Lineo on the Zaurus). You program it just like you would a 1.1.8 application and then you can test it by running pjava.exe which is included in the personal java 3.1 download from Sun. There is also a program called JavaCheck that will ensure that your app will run properly in PersonalJava. As for the Palm, MIDP for PalmOS is a 574K program that installs on your palm device. You then use the J2ME-WTK (wireless toolkit) to build a JAR/JAD file and you use the MIDP API to write the code.
