use of globalContext and variable file name in lookups and main flow

[_AnonymousUser]

We have a job wherein we have to lookup multiple files but the file names are not constant. So I have to iterate thru the main file and get variable part of the file name and use that for lookup files. However when running the job, the lookup files fail coz they seem to processing before I iterate the main file to get the variable extn!

Hi
Can you please show us the more details of your job? I think there must be a job design issue. The job looks like:
tfileinput1--main(row1)--tFlowToIterate--iterate--tJava--oncomponentok--tfileinput1--main--tMap--out1--
                                                                                                                              |
                                                                                                                           lookup
                                                                                                                              |
                                                                                                                        tfileinput2
tfileinput1: read the lookup file name from a file and then iterate each one
tJava: store the current lookup file name to a context variable, let's call it context.filename, eg
context.filename= (String)globalMap.get("row1.colName")

tfileinput2: set the file path with context variable, for example:
"d:/file/"+context.filename
