Program ab issue
 
 

when using the ab.jar in eclipse I get the following error when trying to run the bot.
“Could not find class ‘org.alicebot.ab.Bot’, referenced from method…”. The chat class is being imported but the bot class cannot be imported.

Here is my code:

import org.alicebot.ab.Bot;

}
  else{
   
//do nothing
      
}
  }
  }
);

scv.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        
public void onGlobalLayout() {
            scv

                    scv
.fullScroll(View.FOCUS_DOWN);
                
}
            }
);
        
}
    }
);
   
}

   } 

I have imported the external library and defined the classpath for it. I have also copied the ab.jar in my project folder and even defined the classpath for it. But nothing seems to be working. Am I doing this wrong or are there more libraries that are needed for this to work. Anybody have a solution to my problem?

The first place I would look is here…

i replaced the if/else with while. Same problem

 

 
  [ # 3 ]

I would change it back to if/else and put some sort of diagnostic code inside the else block, just to see if that’s where it’s failing. Probably something like displaying the contents of the variable usertext, to make sure that it’s not coming in as an empty string (which is what it seems to be doing).

I would try what Dave just said.

Then, at the top, I would try adding something like…

package org.alicebot.ab

Or, maybe the CLASSPATH is not set, so Java can’t find org.alicebot.ab.*

I tried what dave suggested. The app won’t even start. I’ve already set the classpath but the same error is coming up. I’ve checked the .classpath file in my project and the path for the library is there. The package is defined at the as

package com.example.test3

If the fact that it won’t even start, is a change from what it was doing before, then Dave’s advice was good for troubleshooting purposes.  At least you know now that when you take Dave’s suggestion, something different happens. 

For one thing, the syntax error “Could not find class ‘org.alicebot.ab.Bot’, referenced from method…” disappeared, correct?  If so, that may be a hint to solving this issue, or a section of source code that may be cleaned up a bit.

What’s “package com.example.test3;”?  If for comparison “package org.alicebot.ab;” equates to http://ab.alicebot.org then “package com.example.test3;” equates to http://test3.example.com.  It looks like that may be ALPHA code syntax used as a guide that was supposed to be cleaned up.

Presuming you are on Windows, what do you see when you type this at the command line?

echo %CLASSPATH

I should have worded that reply better. The app hadn’t started before and currently has the same problem. The error didn’t disappear, it is still showing. I forgot to mention that.

I’m using eclipse and when starting a new project eclipse automatically defines the package for us.

I used that code as it was given in the program ab documentation. Since it was for java I thought it would work for android as well. Perhaps I am doing something wrong here. Can anyone knowledgeable in android check out program ab.

8 Step Tutorial: Running Program AB on Ubuntu Linux 12.10 64bit

1. Goto: https://code.google.com/p/program-ab/wiki/RunningAB
2. Download link “program-ab.zip”: https://code.google.com/p/program-ab/downloads/detail?name=program-ab.zip
3. Make Directory for download: mkdir ~/programAB
4. Change Directory to download directory: cd ~/programAB
5. Extract “program-ab.zip” inside download directory ~/programAB
6. Create shell script “run.sh” with text editor inside download directory ~/programAB

#/bin/bash

/usr/bin/java -cp out/production/Ab Main bot=super action=chat trace=false 


6. Make shell script executable with:  chmod +x run.sh
7. Run Program AB with: ./run.sh
8. Please suggest improvements to this tutorial.  For now, you should see something like this ...

I am using Windows.

Ishwor,

I’m installing Eclipse now on Ubuntu Linux.
Then, I’ll take a look at the Android SDK which includes a mobile device emulator.
This may turn out to be a fun educational hobby to try to solve this issue the hard way.

Yet, I think most readers may enjoy the new CallMom app for Android
as the much easier option… https://play.google.com/store/apps/details?id=com.pandorabots.callmom
In my honest opinion as a hobbyist, it is important to support A.I. companies in our chatbot community.

Thank you very much I appreciate your help. I am developing this chatbot for an academic project so that is why I am not using callmom. Maybe after this project I can look into it.

Sadly I’m away from my work computer for another week and a half, and the laptop I have with me isn’t suited for testing this problem, so I’m going to leave the assisting in 8Pla’s capable hands. Sorry I can’t be more helpful right now. Ill be back from my trip to England on the 10th of April, and back to work on the 11th, so we’ll see at that point, but I think this will be solved by then. cheese

I downloaded and setup the ADT Bundle from:

http://developer.android.com/sdk/installing/bundle.html

And, on the site it claims…

That’s it! The IDE is already loaded with the Android Developer Tools plugin and the SDK is ready to go.

However, their own demo project loaded in the IDE is not ready to go, since it fails with error:

Your project contains error(s), please fix them before running your application.

Funny, they try to blame my project in the error! 

I don’t even have a project, yet.

So, their error should put the blame on them:

Our own demo project contains error(s), that we didn’t fix, so our demo failed.

hi Ishwor,
I am vijay vankhede. We have talk about this error at program-ab issue-5. I am also developing chat bot android application for my final year project. I think we have to look at program-o which is aiml php interpreter. We can build chat bot based on client server architecture unless embed aiml app.

I have no problem moving to program O but can we use that in android? I don’t want to look into program O unless its fruitful.
