Hi Martin,
I originally had the List as an instance variable for the Page but when I
would open a new browser tab, the original page would crash and a
nullpointerException would be given because the page reference lost
reference to the object.
So now I create in the page constructor in instance of BatchLines and pass
it along through method parameters.
The thread is started from a method called in the constructor. Here is the
def of this method:
/****************************************************
* Method: beginProcessing
*
* Invokes workerThreads
*
* returns: void
****************************************************/
private void beginProcessing(List batchLines)
{
fullReportDwnLoadBtn.setVisible(false);
try
{
csvFileCreater = new CSVFileCreater(LOADER_CSV_FILE_NAME);
if(turnOnLoader)
{
BatchLoaderProcessingThread threadJob = new
BatchLoaderProcessingThread(stringList, batchLines);
loggerThread = new Thread(threadJob);
loggerThread.start();
}
else
{
BatchDeleteProcessingThread deleterThreadJob = new
BatchDeleteProcessingThread(stringList, batchLines);
loggerThread = new Thread(deleterThreadJob);
loggerThread.start();
}
} catch (IOException e)
{
// TODO Auto-generated catch block
log.error("Inside beginProcessing() throws error: " +
e.toString());
BatchProcessPage.this.error("An error has occurred
starting creation of
CSV file");
}
}
Here is the definition of the thread class:
class BatchLoaderProcessingThread implements Runnable
{
List stringList;
List batchLines;
public BatchLoaderProcessingThread(List stringList, List batchLines)
{
this.batchLines = batchLines;
this.stringList = stringList;
}
@Override
public void run()
{
processLine(stringList, batchLines);
loaderFinished();
}
}
processLine is a method that is part of the Page class.
