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.

  • 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.

  • Managed system SOL~JAVA does not fulfill the Diagnostics prerequisites

    Hi Experts,
    I am getting error error while doing manged System configuration in Solman through solman_setup.In step 2 during prerequisite check I am getting error "Managed system SOL~JAVA does not fulfil the Diagnostics prerequisites" for java and abap too. In LMDB I checked the Host assigned to this technical system.Please refer screen shot for the entry. Please suggest where I am committing  mistake.
    Thanks

    Thanks Karthik & Kamil,
    During SLD preparation in System Preparation phase I had updated the CR/CIM of SLD but I committed a mistake that I applied the CR (From 8.x to 9.0) and then (From 9.x to 9.y) without doing it sequentially from (1.x to 2.0) then from (2.x to 3.0) and so on as per 669669. It didn't give any error.As of now it is showing CIM1.6.38 and CR 9.13. Is my current problem related to this?
                                                                                                                                                    Current error message is saying (The definition of Technical System 'SOL~ABAP' is not correct: 'SOL~ABAP': Technical System must be installed onat least one Host.) similarly for Java (The definition of
    Technical System 'SOL~JAVA' is not correct: 'SOL~JAVA': Technical System must be installed on at least one Host.).In LMDB I can see in technical system Abap and Java has host assigned to it.Plz suggest.

  • I am trying to revert my Java to 1.6 from 1.7. The System Preferences Java icon is disabled. But when I enter java -version in terminal it shows 1.6.0_65.  Please help me in giving explicit commands to get back my Java 1.6

    I earlier had a java 1.7 installed in my system.  I wanted to revert the version back to 1.6.  I downloaded the file JavaForOSX2014-001.dmg and installed it in my hard disk.  I am not sure where it has installed it but it has successfully done it.  When I open up the terminal and enter java -version it shows 1.6.0_65 version as the java version. 
    But in the System Preferences, Java is disabled and does not show the java as being installed.  Please guide me in getting my java 1.6 back.

    The preferences pain shows this message when I click on the Java icon -- “Java can’t be opened because it isn’t available".

  • Hi i wrote a java program for scanning a system for java.exe 's

    hi ,
    i wrote a program which scans the system for java.exe 's and then it captures them in a linked list and then i
    iterate through it for "\\Java\\jdk1.5.0_08\\bin\\java.exe and my aim is to return true in case the linked list contains the string "\\Java\\jdk1.5.0_08\\bin\\java.exe" and stop scanning the system.
    If the linked list does not contain "Java\\jdk1.5.0_08\\bin\\java.exe" it should return false.
    But my problem is the program is continuing to scan the system even if the linked list has "\\Java\\jdk1.5.0_08\\bin\\java.exe"
    Any sort of help is appreciated.

    In last 45 days or so, Bloomberg video no longer plays.

    Do you use Glimmerblocker, or any other advert/content/security blocking/filtering software ?
    Yes, I use Sophos.  But, recall that with another browser (Chrome), video plays fine.  So the issue is not with Sophos per se.
    Safari-Preferences-Extensions is set to OFF ?
    I just turned Safari-Preferences-Extensions to OFF.  Video will sill not play.
    Regarding;"
    check System Preferences - Flash Player - Storage tab to see that 'allow sites to save information..." is on.
    In the Advanced tab -  click 'delete all'  ?"
    I did this, but, I an unable to delete all the Site Data; I get an error box:  "Flash Player was unable to delete all local storage. The files may be locked by another program. Close all browsers or restart your computer, and try again."
    I get this error even with all the browsers are closed.
    I think this points to our bug:  Only in my Mac OS user profile and only in Safari there seems to be some Flash Player file which is either 'open' or 'locked' to deleting.
    Where could that pesky file be????

  • Winhelp Help system and Java

    Hello,
    Of the several products we develop, one, a Java program, uses the Java Help help system (logically). The others use a standard Winhelp help system (developed in Robohelp). Our current workflow for developing a help system for the Java program is to batch convert the Winhelp RTF files into HTML files. The problem is, most of our Winhelp formatting is either dropped or incorrectly represented in the Java help file. Also, I prefer the look and feel of a Winhelp system over Java.
    Is it possible for a Java program to be modified so that it supports a Winhelp help system and not a Java Help system? If so, how is this done, and where can one find information on the process?
    If not, what options do we have to "pretty up" the Java output from the conversion?
    Thanks!
    Todd

    Thanks for your response. Could you direct me to a resource that explains the steps for accomplishing this? I'll need to provide the development staff with instructions.
    Thanks again!

  • Does the Flashback malware have an effect on OS X systems without java installed?

    Does the Flashback malware have an effect on OS X systems without java installed? Just asking since i do not have java installed...

    It's not likely, but better safe than sorry. See
    Helpful Links Regarding Flashback Trojan
    Visit Thomas Reed's site for insight and help: Mac Malware Guide
    A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started. However, be careful about what you do as new variants of the malware circumvent the efforts of earlier tools.
    Also see Apple's article About Flashback malware.
    Apple has released Java updates for Snow Leopard and Lion users:
    Java for OS X Lion 2012-003; available only for users of Lion with Java installed.
    Java for Mac OS X 10.6 Update 8; available only for users of Snow Leopard.
    Flashback malware removal tool; available only for users of Lion without Java installed.
    Install whichever shows up in Software Update. It removes the malware (if present), updates Java (if present) and tightens up Java settings for the future.  You may download from Apple's web site instead of using Software Update, but it's important to know which one to get, because the other two won't work for you.

    Dear Jan,
    There are number of ways you can identify Java stack,
    Go to SM51 and Check in Message Types, If it is showing J2EE, then it means java stack exits.
    Go to /usr/sap/<SID>/<instance>/ and check if j2ee folder exits then it contains java stacks.
    Go to profile directory and check if SCS profile exits, if it exits then it contains java stack.
    Thanks

  • How can i use the shared object already present in the system from java.

    explanation:
    Actually there are shared objects present in the jdk which is used by java itself.I want to know if i can use the methods in any library file(shared object) which is already present in the system.
    Or the question can be put this way how does the java call the native methods? (Can we do that explicitly) in our code.

    It isn't entirely clear what you mean by 'shared' objects and what the relationship with these shared objects and calling native code is.
    There are no shared objects in the Java language, only the java platform.
    The platform system properties are exposed via the System class (java.lang package).
    You are free to create your own shared objects by using static member access or some other mechanism.
    Your access to methods in any of the API's is dictated by the access type you have, normally public being the only completely open access allowing complete visibility.
    You can call native methods, thats what JNI is for. Calling native methods in classes other than your own is generally done using the API provided by the developer(s) of those classes.

  • ERROR: Unable to locate system class: java/lang/String

    I have swtiched from running my application using sun jvm to using microsoft jvm. When i run it i get the following error:
    ERROR: Unable to locate system class: java/lang/String
    java -classpath out;etc..etc myclass
    has become
    jview -cp:a out;C:\build\rt.jar;etc..etc myclass
    any ideas?

    Search for the old "MS SDK for Java 4.0" somewhere (no, you can't find it at Microsoft's site).
    There are two files that you have to get: sdkdocs40.exe (a file with 10,895,496 bytes) and SDKJava40.exe (a file with 20,222,928 bytes).
    Use the embedded jvc compiler to recompile your program. Beware: try not to rely too much in jvc. Use it only for discover that you're using methods not implemented in JDK 1.1.8, but don't use it for deploying your app.
    You'll discover that you'll have to rewrite large portions of your program, and even change your program specifications to deal with the reduced functionality of the old MS JVM (for instance, say that you'll need to change the 'modified date' of a file.
    In JDK >= 1.2 there's the method File.setModified(); in MS JVM you'll need to use some com.ms.wfc function.

  • Change Business System for Java Proxy Client

    I have created Web AS Java business system for Java proxy.
    Is it possbile to send message from client Java Proxy as another business system (Third party)?
    For example to specify this system
    MessageSpecifier messageSpecifier = proxy.$messageSpecifier();
    messageSpecifier.setSenderService("MY_BUSINESS_SYSTEM");
    proxy.$messageSpecifier(messageSpecifier);

    Yes, it is.
    That's the way to do it.

  • After Restoring/Backup File System XI Java Instances are not up!

    Hello all,
    We are facing problem in restoring the SAP XI System, after taking backup of the system the java instances in SAP XI System are not starting again. ABAP connections are fine.
    Can anyone provide suggestions/solutions in order to restore the XI System back.
    The system information is as follows.
    System Component: SAP NetWeaver 2004s, PI 7.0
    Operating System: SunOS 5.9, SunOS 5.10
    Database: ORACLE 9.2.0.
    Regards,
    Ketan Patel

    I would correct Oracle version is 10.2.0
    I would also like to reframe my problem.
    XI server(both abap and Web) was working fine. Every weekend we take full backup(file system+DB)(UFS) of server. After taking backup server got up and we were able to login through abap but java web page was not openning. We did some troubleshooting it didn't work and finaly we restored the backup and somehow it worked. Next week after backup again same problem arose. We again restored latest backup but this time problem still exists.
    Regards,
    Ketan
