Get value from Row.Column

Anonymous — Sat, 13 Oct 2012 11:11:26 GMT

I try to get a value from a row. I thought it should work like: ((String)globalMap.get("rowX.XXCOLUMNNAMEXX"))
As shown in my example I try a simple print out from row2 like:
System.out.println(globalMap.get("row2.gln_orderedBy"));
Can anybody help me? Where is the error?
Thanks,
Robert

In order to access data flow, should use tjavarow instead of tjava.
On tjavarow, you can access the column value like:
System.out.println(input_row.columnName);

Hi,
I have a column having sum(spend) in tHash component. I want to find nth percentile value for that whole column. I have a java function getPercentile for percentile ready which takes (int k,float...values) as arguments. How can I pass all values in column sum(spend) to this function?
Thanks and regards,
Himani

I want to retrieve all the values of tJavaRow return by tFilter using tjava.
I already tried to put these row values into globalMap values but it returned only the values of last row.
If anyone know the solution please suggest me.
