ability to scrape this site (frame and javascript)

");
//(I MODIFY THIS PATTERN BCOSE I READ THIS (

Matcher m = p.matcher(scrapeableFile.getContentAsString());

// Si on y trouve un "div" avec ce "ID" (comme on attends)
if (m.find())
{
String details = m.group(1);
// Et maintenant, entrez les "patterns" que vous désirez trouver. Un example suis:

// Celui extraira chaque jour qui liste des heures. Si le jour (comme dimanche) dit "fermé",
// nous n'allons pas trouver des informations avec ce pattern.
Pattern p = Pattern.compile("
]*>(\\w+) ]*>([0-2][0-9]:[0-5][0-9]) ]*>([0-2][0-9]:[0-5][0-9])

");
// I MODIFY (\w+) TO (\\w+) BCOSE SCRIPT DO A ERROR IN RUNNING
Matcher m = p.matcher(details);

while (m.find())
{
session.setVariable(m.group(1).toUpperCase() + "_OPEN", m.group(2));
session.setVariable(m.group(1).toUpperCase() + "_CLOSE", m.group(3));
}
}

So, i try to write all in a file with this script :

FileWriter out = null;

try
{
session.log( "Writing data to a file." );

// Open up the file to be appended to.
out = new FileWriter( "test.txt", true );

// Write out the data to the file.
out.write( dataRecord.get( "ID" ) + "\t" );
out.write( dataRecord.get( "NOM" ) + "\t" );
out.write( dataRecord.get( "RUE" ) + "\t" );
out.write( dataRecord.get( "NUM" ) + "\t" );
out.write( dataRecord.get( "CODE" ) + "\t" );
out.write( dataRecord.get( "VILLE" ) + "\t" );
out.write( session.getVariable( "JEUDI_OPEN" ) );
//ONLY ONE FOR TESTING
out.write( "\n" );

// Close up the file.
out.close();
}
catch( Exception e )
{
session.log( "An error occurred while writing the data to a file: " + e.getMessage() );

And i receive this message :

Untitled Extractor Pattern--DataRecord 3:

NUM=69

LINKID=32000938

result: Processing scripts after a pattern application.

Writing data to a file.
An error occurred while writing the data to a file: null

Why SessionVariable is not writed?

Kind regards
