Currently i having an Assignment of AI(Artificial Intelligence) to develop an Expert System. We are using SWI-PROLOG as our practical class learning software, and now i am trying to apply e2glite to my Assignment.
I found that e2glite is able to download from www.expertise2go.com, and this website also providing the instruction and example. According to their instruction, computer must have Java(already installed).
So now i am trying to preview the sample that i had downloaded from the website, i am able to view the interface, once i click the "START The Consultation" is giving me "ERROR 800: MUST QUIT". In debug mode, it show me "Found on line 0 (below) before character 1 null"
According to the www.expertise2go.com, the meaning of error 800 is "Missing or Empty knowledge base". But i am follow exactly as the instruction to do it. I don't know where am i doing wrong.
P/S: i can view sample from the website, but no from my computer
Problem solved due to the java version is too updated.
Thus i downgrade the version from Java 7 Update 25 to Java 7 Update 13.

I have one program, I maintain, that was originally written in Oracle Forms 6i. A while ago I migrated it to 11g. Our users access this Oracle Forms program through their Internet Explorer browser on their Windows 7 machines.
The problem has been that the program only seems to run well for our users, when they have Java 6 Update 45, installed on their machines. Going to a newer version causes problems.
Today, I wanted to get this resolved, so I updated my PC to Java 8.31, and attempted to access my Oracle forms program using IE. (Thanks to Viewing oracle app and getting: java.lang.ClassNotFoundException: oracle.forms.engine.Main I was able to get the form running again in my web browser.)
When my form ran, I found the tab key wouldn't advance to the next field on the login dialogue box. But after I logged in the tab key worked. (The tab key initially not working is a small thing, but it has really annoyed some of our users.)
I then used several different forms. Some worked just fine, no problems. But then when I clicked a button, on one form, it would endlessly try to complete a request; to the point that I couldn't even close the web browser to stop it. (Finally I just used task manager to end my web browser’s process.) This seemed to go in line with what some of our users have reported: (when attempting to use the latest Java) that the Oracle forms application just stops working completely after a while.
Because of these issues our users want to keep Java 6 Update 45 on their machines. I know this is a major security hole, but I haven’t quite nailed down what the solution to it is.
Has anyone else had a similar issue? We're running Oracle Fusion Middleware 11; specifically Forms Services version 11.1.2.0.0
Thanks.
Well this may not be a question that needs answering after all.
I've done some more testing since asking this. Besides the login dialogue box (not responding, as it should, to the tab key) everything else works just as it should.
I still have one form that hangs; but that’s all (and it may be caused by something else). All my other forms seem to work just fine.
I talked with one of my co-workers, and I realized we really need to investigate and determine what version of Java our users really are using. They may not have used the most recent version of Java; which I used with success, today. Or some may be already on it; and that's why they aren't complaining.
At any rate more research, is needed on my part. Thanks to all who read this. If any of you have had similar experience in something like this, still feel welcome to answer/comment.
I continue to get out of date message when trying to view an applet. The applet checker informs me that I have the correct version. I have the security settings correct but still no joy. When trying to go through the update it stops TO inform me that I have a later version already installed, which is correct. On a Mac OS 10.9 I could show you the screen shot but don't have the points. Bugger
Thanks for those who have replied and I'll try to elaborate further.
JavaApplets do run from the java web site. The creation of my own applets don't run. I have done some research and it would seem that under version 8 all JApplets must be signed. This would explain the message I receive. Also the link below may explain what the problem is. Sorry but I don't have the 10 points yet to be able to send a screen shot.
Again runnin the update (version7 downloads) stops to inform me that I have a later version installed (version 8). So you can see that things arn't perfect

Ok, I recently wrote a program for my fathers company. I tested it on both of my computers, my dad's computer, and my mom's computer before he sent it out. He sent the beta version to his CEO, and 4 others. It worked just fine for the CEO and 3 others. However, one person got an error when he tried to open the program that said "The main startup class could not be found."
I know that this means it could not find the main class or method, I just don't know why. He said he installed the latest version of java and I provided the right download link when I distributed the program. How can I fix this problem?
There are a number of different factors that can cause this, but the most probable is that the computers don't have the appropriate Java Version.
My approach to solve this is to make the program in Java 5 standard. The very most part of the computers today should have at least JRE5.
As you are developing in NetBeans, try changing the compiling level of your project as described here
Today while programming, I suddenly started to get a JVM Error 104 and the except read "Error starting XXXX: Module 'XXXX' attempts to access a secure API". I hadn't gotten them before and I wasn't doing anything too radical. I undid my work to a point where it was previously working and the error continued to show. I am aware that certain functions require code to be signed, but the documentation says that even functions that need to be signed will work in the simulator. (using JRE 4.6, version 1,1 of the plugin, on a Bold 9000 simulator)
Any ideas on how to remove this error so I can continue working?
EDIT: I noticed that it works fine on the "Blackberry-SDK - 8900" but I get the error when using the "SimPackage - 4.6.0.307_9000 - 9000"
EDIT: It only seems to be a problem with the "SimPackage - 4.6.0.307_9000 - 9000" simulator which I downloaded seperately from the Blackberry Developers page.
EDIT: Clearing simulator data seemed to do the trick
You haven't mentioned which development environment you're using. If it is JDE, goto Edit -> Preferences, select the Simulator Tab and ensure "Enable Device Security" is un-checked. If you're using Eclipse you will have to find the appropriate mechanism or perhaps someone eles knows.
I could swear that just a couple of months ago I downloaded a copy of the Java 1.5 SE JDK and I did not have to give them information on my first born. Today, I had to go through the register-and-we-will-send-you-a-link-someday dance. I have not received the link yet, so I thought I would ask about it here.
What is special about the Java 5 JDK? I can get Java 6 just by clicking, is this a stick to get us to migrate to Java 6?
Am I just not remembering doing this before?
What marketing genius thought this would be a value add for Java? "If we make them sweat for the JDK they won't just delete it willy-nilly the next time?"
Does everyone picture the people designing systems like this as mustache twirling Snidely Whiplash clones like I do?
Did I just miss the link for the Secret Squirrel route to the download page?
Finally, I am in the U.S. so I should not have to worry about export restrictions.
Any thoughts?
P.S. Did I mention I am trying to get the Java 5 JDK ;-)
Java 5 has passed its sell-by date on October 30, 2009. That means that support is only available as paid business support, which of course requires registration.
You shouldn't really be using Java 5 anymore, unless you're committed to some large, complex installation, in which case you should seriously consider that paid business support - I guess the automatic registration page is intended to drive home that point.
Edit: You can still download Java 5 without registering via the technology archive. (Not any more, it also requires login now.)
Go here. Click "Download" (left). Then click Skip this Step (it's tiny on the bottom of the new widget that appears when you click "Download").
EDIT:
For JDK 5, go here, click "Download" and then just click Continue to Download without entering anything in those fields.
There's a link that says: "Skip this Step"
