I am testing cron block and found out some problems. I am using the
TestCronJob supplied. I have uncommented the trigger section so the job is
scheduled automatically at startup (
<trigger name="test-job1"
target="org.apache.cocoon.components.cron.CronJob/test"
concurrent-runs="false">
<cron>*/12 * * * * ? *</cron>
</trigger>
Below you will find the log with errors. For some first runs there is a NPE in
sitemap. After a while it starts working with no problem. Looks like the
sitemap is not ready to receive requests?
