Hi dudum,
What's your job requirement? Do you want variable value in parameters of tWebserviceInput from previous component(tjavaflex)?
Can you please explain your request with some example data so that we can give you more accurate answers.

Best regards
Sabrina

Well , I have tjavaflex component and i want to generate new output rows (flow),from the java code.
what i mean it is not based on input component, just generate them in the code and output as flow

You can do this in a simple way by doing something like the following.....
Start Code

for(int i = 0; i<10 ; i++){

You are opening a FOR loop here, but not closing it.

Main Code

row1.column1 = "Column1";
row1.column2 = "Column2";
row1.column3 = "Column3";

You are creating your data row here. I am assuming an output row named "row1" and a schema with the columns used above.
End Code

You are closing the FOR loop here.
If you plug that in, you will generate 10 rows of data.

I always get caught out kzone. It should just use the input and output row names as far as I am concerned.

i like the way " input_ & output_ syntax" ... they are independant of the name's flow (and the fact that propagation not always efficient

If you set the loop to iterate 10 times, you will get 10 rows generated.
