how to invoke a Tagsoup from a java code???

Use System.exec(..)
See: http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html

thanks MArk,
but I have error:
com\psol\xbe2\Final.java:21: cannot resolve symbol
symbol  : method exec (java.lang.String)
location: class java.lang.System
            System.exec("java -jar tagsoup-1.0.4.jar"+ url+" > ca.xml");
                  ^

package com.psol.xbe2;

import java.io.*;
import java.util.*;
import java.lang.*;

public class Final
{
    private final static String file = "ex1.txt";
    private final static String base = "http://moneycentral.msn.com/detail/stock_quote?Symbol=";

    public static void main(String[] args)
        throws IOException
    {
        String symbol;
        BufferedReader in = new BufferedReader(new FileReader(file));
        while((symbol = in.readLine()) != null)
        {
            String url = base + symbol;
            System.out.println(url);
            System.exec("java -jar tagsoup-1.0.4.jar"+ url+" > ca.xml");

        }
            in.close();
    }
}

Its Runtime.getRuntime ().exec ()

And you might want to store the command "java -jar ...." in a properties file and load it from there, so that you can keep changing it on runtime without modifying your source code.

>> in.close();

Put that in a finally block.

the error fixed but
      Runtime.getRuntime ().exec("java -jar tagsoup-1.0.4.jar"+ url+" > ca.xml");
not excuted!!!

Where is the JAR file located? Is it in the same directory from where this class file is being run?

yes!!

What is the output you get?

http://moneycentral.msn.com/detail/stock_quote?Symbol=ca
http://moneycentral.msn.com/detail/stock_quote?Symbol=da
http://moneycentral.msn.com/detail/stock_quote?Symbol=dell

but the ca.xml not created!!!!!

use --files flag instead of the >.

java -jar tagsoup-1.0.4.jar --files http://moneycentral.msn.com/detail/stock_quote?Symbol=ca"

I should output the reselt to ca.xml

also java -jar tagsoup-1.0.4.jar --files http://moneycentral.msn.com/detail/stock_quote?Symbol=ca" did not work

I am unfamiliar with tagsoup, but you can also redirect the standard output:

System.setOut( ... );

I tried to use it but I had the following error

com\psol\xbe2\TextAreaOutputStream.java:54: <identifier> expected
System.setOut( out );
             ^
com\psol\xbe2\TextAreaOutputStream.java:57: <identifier> expected
System.setErr( out );
             ^
com\psol\xbe2\TextAreaOutputStream.java:60: <identifier> expected
System.out.println( "Hello World" );
                  ^
3 errors

// redirect standard output stream to the TextAreaOutputStream
System.setOut( out );

// redirect standard error stream to the TextAreaOutputStream
System.setErr( out );

// now test the mechanism
System.out.println( "Hello World" );

}

Don't forget to correct the version number of the tag-soup jar.

Thanks aloooooot Mark :-)

So no points for telling Runtime.getRuntime ()....

Hi Mark,
Can u please explain why you do this

boolean done = false;
            while(!done)
            {
                try
                {
                    p.exitValue();
                    done = true;
                }
                catch(IllegalThreadStateException itse)
                {
                    try { Thread.sleep(20); } catch(InterruptedException ie) {}
                }

                // Do whatever you want with the output
                while (std.available() > 0)
                    out.write(std.read());
            }
        }

Keeps the stream from the tagsoup streaming to the file, until the process is finished.
