Hi people
I am wondering is thare any easy way to store job variables (configuration) in external config file, so I'll be able to change (for example) input and output directories, db connections etc. withot changing complete job, just config file.

Regards!

Hi
You might use the tContextLoad component.

I am using this schema
tFileInputDelimited--row11-->tContextLoad--onComponentOk-->MsgBox(context.test)
but I am getting this error 'test cannot be resolved or is not a field'.
In input file I have 3 rows:
test;testing
nTest;nTesting
mTest;mTesting

Hi
Have you added a context variable called test in your job?
According to the data in delimited file, you need to add three context variables(test, nTest, mTest).

Thank you good sir! You introduced me to the magic world of contexts
Basically, creating a context group, defining few variables and linking context with job is answer for my question. I've just find that exported Talend job keeps context variables in file ~\\talenddemosjava\job_name\contexts\Default.properties which I can change as I wont.

Best regards!
