Tutorial issue: Job compile error

Anonymous — Thu, 20 Jul 2017 12:36:19 GMT

Hi, I searched for this on Google, but the solution was on the old forums, and I also read the old forums were archived instead of migrated here, which I assume is the new version (I think it wasn't a clever decision to dump so many solved issues for a Joomla!-looking forum UI, but that's just my opinion), thus I couldn't read the solution and had to come here to ask again.

Long story short, I followed the tutorial step by step: Create input and output components, add a mapper and propagate data from a pre-built CSV to an empty one. All good until I press run and it returns some odd error in code which is likely caused by me skipping some step.

The error pops on the output file component, can someone point me in the right direction here?

PS: The tag system is really awkward.

It's hard to diagnose without more information, but usually that error means you have a typo in the parameters for that component (e.g. an extra ")"). Have you enclosed all the parameters that will be referenced by Java in quotes? That's a mistake I've made multiple times

Good luck!

Thanks for the quick answer.

I checked again and it seems the output file path NEEDS quotes for some reason. I thought it would be parsed properly in the code behind.

Rather counter-intuitive, that was the solution exactly.

The platform needs to interpret string literals and variables (or both) in component settings, and one or the other needs a delimiter. Talend's design choice hews closely to the Java code it creates, with string literals wrapped with quotes and variables without.
