Using Java to Develop Expert System

Can anyone help me to find some information about how to use JAVA to develop an expert system

You can build expert systems with JAVA - that is not a problem. For starting, a good place will be Philip LaPlant's book. It does give good insight into expert systems.
With Java, the systems might get a bit slow though, the processing in these systems are usually very high.

Can I use Java Card Development Kit 2.2.1 on Windows XP?

Can I use Java Card Development Kit 2.2.1 on Windows XP?
If no, which kit supports XP?

It is not as strait forward as per say.
I would like to share some tips that I have learnt duirng my recent experience with Java Card Development Kit 2.1.2 ( It presumed that JAVA SDK and JCDK is properly installed:
Additonal installation
- you need to download Java Communicatons API version 2.o for Windows at http://java.sun.com/products/javacomm/downloads/index.html
- unzip the downloaded file javacom20-win20.zip
- copy comm.jar and javax.com.properties to %JAVA_HOME%\lib
- copy win32com.dll to %JAVA_HOME%\bin
Configuration of Environment
- Activate System under Control Panel
- Click Environment Variable button under Advance Tab.
- Check that JAVA_HOME and JC21_HOME are there under User Variables for user123
- Create a new enviroment by clicking New button under User Variables and Enter "CLASSPATH" for Variable Name and ".;c:\j2sdk1.4.1_04\lib\comm.jar for Variable Value ( the ".;" is important for the entry and varies according to your JAVA_HOME)
Modifying %JC21_HOME%\samples\build_samples.bat
- Next you need to modify the compiler option in build_samples.bat
- Use editor to look for the portion "Compile Sample" and add "- target 1.1" to every statements here. A sample is listed below:
%JAVA_HOME%\bin\javac -target 1.1 %JCFLAGS% src\com\sun\javacard\samples\HelloWorld\*.java
You may proceed to test the demo codes as instrucrted in the User Guide.
I hope the above will help those who are keen to have a head start in Java Card Developemnet.

Safari cannot support Java 7., how can I use Java 6 developed by Apple?

I was told to go the Terminal page and to key in the scipts provided by Apple but still could not get rid of Java 7 and restore to Apple's Java 6.
The plug in is now blocked.

Who says you can't have Java on a Mac. Just make sure you have the latest version, downloaded from http://java.com/en/download/index.jsp or thru the Java Control Panel if you had installed the previous Oracle-released version.
Here's my Safari window (also works in the other browsers):

Expert system in Java

i learned about Jess , a Java-based tool used to develop expert systems through this forum...it's quite useful though coz i'm on the verge of developing my own system, which contains NLP(natural language processing) features as well...any comments? or any other alternative tools tht i can further investigate? Thankx

Using the following search string
java "expert system"
in google produced 14000+ hits. Amoung them Jess. There are probably others.

Running System Commands using Java

HI,
I am developing an application using java which requires some system commands to be run.For example i have to write a java function which can program the windows scheduler to run a particular executable at some time & another one to initiate an ftp.I however do not know how to execute the corresponding commands from java.Is there any way or some specific api(similar to the system command in c) that i can use to perform these operations.I am using j2sdk 1.4.0_01 on a win 98 machine to develop the application.

See [url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html]java.lang.Runtime

Kernel programming using Java

I'm currently doing a research in computer security and would like to develop a system which can deal directly to linux kernel in order to enhance the security. During my research I found that Java is a type-safe language which is more secure if I develop my system compare to C language which is lack of type-safe. So I decided to use Java to develop my security system which will enhance resources management in Linux. My question is, does anyone know whether Java could be used in kernel programming or not? Where could I get some sort of references related to my work especially tutorial about kernel programming using Java. I would appreciate if anyone of you could help me in this matter. TQ

I'm currently doing a research in computer security ...You might want to do a bit more research into the languages.
What you are discussing has nothing to do with security.
If you are writing kernel services then java is probably ill suited because the normal implementations use garbage collection which is not under your control. This makes it hard (if not impossible) to control timing.
If your sole desire is type safety then C++ provides better type safety and provides more control over types as well.

Pattern matching for thumb print scanner using java

I want to get some information about security system technology using java to develop my final year project. Please kindly assist me in searching some related information regarding thumb print scanner security system. Anyone who can help me in this, i will really appreciate it, thank you in advanced !

This is going to be a tough project. Here are a couple of ideas
1. Java, or whatever language you do it in probably won't matter that much.
2. You need to find algorithms for matching fingerprints. There are probably some out there... You may need to pay to use them. There are also probably some books out that might help you figure out how to do this, or how other people have done this, or who to contact about doing this.
3. Partnering up with someone, either in industry (like IBM maybe) or at the very least a professor is going to be important.
4. Don't try to invent the wheel. Do your research and reuse as much as you can. Getting the algorithm + the scanner are going to be the hard parts

How can I use java with DMI(Desktop Management Interface)? Help please..

I want to use Java to develop DMI. Please help...Thanks.

You are not getting replies because your question may need a course to answer. Just like, hey, can someone tell me how to write an email application? Or,
Can someone show me how to build a house?
Start writing your application, when you get stucked, post your questions.
Or, at least be more specific. Like, elaborate DMI and things like that.
Do a search on DMI, you may find what you need.

Who can introduce the development contents of the project using java ?

Hi , Web Dynpro experts:
    Could u introduce the working contents of the project using java ?
    1. Do you develop function that would run in a sap standard system(such as CRM ,internet sales)? OR develop a completely independent web application base on client's demand(EJB,JSP,HTML)?
2.Do all the user interfaces run in web browser ?
    In a word ,I just want to know what picture is it as you are using java to work on SAP ,Because I must study AP&JAVA duo to the coming project. Could you explain it for me about SAP&JAVA in any perspective according to your project experience .
   BTW: I have 2 years experience on J2EE and 1 year on ABAP. So how i should get started ?

Hi Guixin,
The most common structure for building a WebDynPro application is to expose functionality from underlying systems and present it using the WebDynPro UI. Often the underlying system is a SAP ERP/CRM type system, but can also be any WebService compliant system, or a combination of both.
Using the Netweaver System Landscape Directory (SLD), WebDynPro can send and receive data independantly of the source. SAP ERP/CRM systems will expose their functionality using RFC-enabled BAPIs. These functions can be standard SAP delivered modules or custom developed using ABAP.
The choice of where to develop your business logic really depends on the history/strengths of your organisation. If you have a strong history of ABAP development in SAP, then it would be recommended to use ABAP for your business logic and WebDynPro for UI. If J2EE is the strong suit, use that instead.
The WebDynPro interface runs in a browser (either IE or Firefox) however there is a beta version of a WebDynPro GUI for Windows which may offer some performance improvements.
HTH,
Jonathan

How to develop a discussion forum using Java?

I am actually developing a forum using Java. That would actually include registering process for a new user and if the user has an account, he can log in. The program should then generate a welcome message and a randomly-created password of 8 char (char+digits), this wil be printed on the screen. I am quite a newbie in this area.. Appreciate for ur help
Thanzz....

and what is more import than actual programming when making a software like a forum system is the database design.
so first you have to designe your database
decide which data that you have to store and decide what are the table that you will need and what columns that you want in the tables
thats where you should start

Developing Xlets using Java 1.5

Hi Folks,
Does anybody knows that is it possible to develop Xlets using Java 1.5. I tried to write some using NetBeans 5.0, and jdk 1.4. ?
Cheers,

With the current download from reference implementation from
http://java.sun.com/products/javatv/
I found I had to make a few changes to get anything to work well. First, I found that there is some kind of XML parsing error (not due to a file being bad but something else):
java -cp samples\runxlet;javatv.jar RunXlet SvcDispXlet
and it brings up a window but nothing is rendered. The output I see is
Running Xlet named: SvcDispXlet
ServiceFile: com.sun.tv.receiver.ReceiverFile
JMFProperties: readProperties
Running Data from Class = com.sun.tv.receiver.ReceiverFile
Parsing failed: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequence
Exception: Invalid byte 1 of 1-byte UTF-8 sequence., file: lib\JavaTVSampleFile01.xml
XletContainer constructor
ROOTFRAME: OTHER 0:com.sun.tv.XletContainer[,0,0,0x0,invalid,hidden]
so I had to change
lib\JavaTV.properties
ServiceFileHandler=com.sun.tv.receiver.ReceiverFile
# ServiceFileHandler=SampleData_01
to
# ServiceFileHandler=com.sun.tv.receiver.ReceiverFile
ServiceFileHandler=SampleData_01
If you want a ServiceContext, try downloading the source and changing
share\javatv\classes\com\sun\tv\receiver\SIEmulator.java
private static ServiceContext svcctx = null;
putResidentXlet(...)
if(svcctx == null){
try { svcctx = new com.sun.tv.ServiceContextImpl(); }catch (Exception e){ e.printStackTrace(); }
AppSignalEvent ase = new AppSignalEvent(dispManager.getRootFrame(),
AppSignalEvent.AUTOSTART, null, xletPath, xletName, svcctx, args);^M
but this still will not give you events. Some Xlet's (like the BdjGunBunny Xlet) wait for suchs events before starting.
C:\Java_ME_platform_SDK_3.0_EA\apps\BdjGunBunny\src\com\hdcookbook\gunbunny\BaseXlet.java
See code in
void waitForPresenting()
* Get a system callback via ServiceContextListener
public void receiveServiceContextEvent(ServiceContextEvent e) {
if (e instanceof NormalContentEvent) {
synchronized(this) {
isPresenting = true;
this.notifyAll();
}

Expert System Development Tool

I am looking for an expert system development tool. I have used Flex, Exsys Corvid and Clips.
I need a tool which has a good user interface too.

I don't know any of your mentioned development tools. But here, on ni.com you will find a really good tool for developing graphically User Interfaces. Check it out and download the evealuation version. LabVIEW.
I don't know why you posted this question on the Lookout forum, but as well NI's Lookout is a great tool to develop fast and easy HMI User Interfaces. As well there NI has an evaluation version. Check it out: Lookout
Hope this helps
