RE: Java API for MOCHASOFT

["Pete Helgren" <pete@xxxxxxxxxx>]

Larry,

I am not familiar with the Mochasoft Java API but you may want to take a
quick look at the tn5250j project at source forge.  They have encapsulated
most of the TN5250 capability into an easy to use bean that makes creating
5250 based apps a snap.

Although there isn't a screen scraper app currently, we are looking at
adding one.  I am currently working on (on and off as most Open Source
projects are ) an HTML based 5250 emulator (like iSeries Access for web) and
I think we can begin to build objects/methods that translate the 5250 fields
into HTML objects soon.  

It is worth looking into if you fail to get resolution on your Mochasoft
API's.

Tn5250j is found at http://sourceforge.net/projects/tn5250j/

Subject: Java API for MOCHASOFT


Mochasoft has a java api for its java based emulator that allows one to
screen scrape.  I have a few *limited* instances where screen scraping would
be an enormous benefit.  This program is really inexpensive and the API
looked easy so I tried it out.

I was quickly able to get the sign on screen and effectively sign on and get
to the next screen.  No problem.

But what I can't seem to do is to get the buffer for any screen after the
intial screen.  Repeated calls to do_read_all() even after a
do_wait_input(100) get the original buffer data for the sign on screen.

I tried longer waits, changing byte variables, NULLing out the buffer array
before the next calls and get the same results.  Since I can watch the
session in a separate window I know I am moving to new screens on the 400.
It just isn't reflected in the do_read_all().

Has anyone used this API?  I was hoping that perhaps someone may have a
simple example of a multi-screen screen scrape that works.

A very simple sample of my test program is shown below for those that want
to look.

Thanks,

Larry


public class Test2 {

        public static void main(String[] args)

        {
                byte buf[][];  // screen 
                
                byte ttt[]={72,72,71,71,71,71,71,72,72};   // very simple
password hiding
                String sss = new String(ttt);                        // save
password as string for later use
                
                api_tn5250 a = new api_tn5250(); 
                
                a.do_load_config("tn5250.cfg"); 
                a.use_display(false,true); // hidden,standalone 
                
                if (a.do_connect("mySystem",23) == true) { 
                        a.do_wait_input(0); 
                        buf = a.do_read_all(); 
                        a.do_goto_field(1);
                        a.do_write_text("LARRY");  //userid
                        a.do_goto(18,6);
                        a.do_write_text(sss);  //password
                        a.do_aid_key(0xf1); //enter key
                        
                        a.do_wait_input(0);
                        buf = a.do_read_all(); 
                        
                                //Print out first line of screen for
identification
                int x=1;
                                for (int y=0;y<buf[x].length;y++){
                                        System.out.println(x+":
"+buf[x][y]+" : "+(char)(buf[x][y]));
                                }
                                System.out.println("");
                        
                        a.do_disconnect(); 
                        System.out.println("\nDisconnected");
                }
                System.exit(0);
        }
}
