I set up a user defined java class that generates a row for each day within a certain timespan. If I test the class using "Test class" everything works as expected. However, when the step is actually called within the process I get the following error:

The code for the class looks like this: import java.util.Date; import java.util.Calendar; import java.text.SimpleDateFormat;

public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException

{

Object[] r = getRow();

if (r == null) {

setOutputDone();

return false;

}

Calendar calStart;

calStart = Calendar.getInstance();

calStart.set(Calendar.YEAR, 2013);

calStart.set(Calendar.MONTH, 0);

calStart.set(Calendar.DAY_OF_MONTH, 1);

Calendar calEnd;

calEnd = Calendar.getInstance();

SimpleDateFormat sdfDatum=new SimpleDateFormat("yyyy-MM-dd");

Calendar cal = Calendar.getInstance();

for(cal.setTime(calStart.getTime());cal.before(calEnd); cal.add(Calendar.DATE, 1))

{

r = createOutputRow(r, data.outputRowMeta.size());

try{

get(Fields.Out, "date").setValue(r, sdfDatum.format(cal.getTime()));}

catch(Exception e) {}

putRow(data.outputRowMeta, r);

}

setOutputDone();

return false;

}

Do you have any ideas on how to solve that problem?
