Schedules workflow not running via cron

Hi,

I have a workflow that I want to run automatically every day. It works fine when I run it command line:

knime -reset --launcher.suppressErrors -nosave -nosplash -application org.knime.product.KNIME_BATCH_APPLICATION -workflowFile="/opt/knime/scheduled/MyWorkflow.knwf"

I put it in the crontab file yesterday:

0 1 * * * knime -reset --launcher.suppressErrors -nosave -nosplash -application org.knime.product.KNIME_BATCH_APPLICATION -workflowFile="/opt/knime/scheduled/MyWorkflow.knwf"

but the expected result was not there this morning. What could be worng?

Thanks/Evert
