I tried different workarounds and I have camel-script added to features in
settings. Any hint on why I get this error and why camel is ignoring the
content of my python script tag? below also is snippet on how i embed python
script:
.....
<route id="VaraExportItemTimer">
<from
uri="quartz2://PS/VaraExport?cron=0/30+*+*+*+*+?&stateful=true" />
<setHeader headerName="previousTime">
<python>
H = dict(line.strip().split('=') for line in
open('VaraExport.properties') if not line.startswith('#') and not
line.startswith('\n'))
if H.has_key("time"):
result = H["time"]
else :
result = '2001-01-01T00:00:00'
</python>
</setHeader>
.....
Thanks!
