Question

I have a job flow like this,

tAccessInput_1 –> tMap_1 –> tSortRow_1 –> tJava –> tBufferOutput_1.
Is this possible to display the data in tBufferOutput_1 in tJava component at every iteration. If possible how can i?

Answer 1

If you’re trying to just output whatever gets input into the tBuffer component, try connecting to a tLogRow component which will spit out everything in the console.

If you want tJava for some other specific reason, here’s a slightly convoluted method:

tBufferOutput_1 -> tFlowToIterate -> tIterateToFlow -> tJava

Then, in tJava, you can do the following:
System.out.println((String) globalMap.get(“row.column”));

where:

row is the name of the main data row between tIterateToFlow to tJava (e.g. row6)

column is whatever schema column you want to output

The data is cast into a String, but in your case it may be an integer or something else.

The reason you need to change the flow to an iteration is because tJava needs to iterate in order to print all rows (as you correctly pointed out in your question).
