File to Idoc : Java Mapping

Question

Hi Experts,
The scenario is file to idoc. In the file i'll be getting name,value pairs. For ex:
Structure is
MT
....Root(1..unbounded)
............Name
............Value
File contains:
Vishal....1
Raj.........2
RFC......10
Rahul.....20
Azhar....15 and so on..
I need to loop through the file. When Name="RFC", I need to make an RFC call with Value as it's input. RFC returns 4 values which will be used for mapping.
Then I need to continue looping through the file. On encountering a particular Name, I need to map corresponding Value to target field.
For this, I should have 2 mappings. One to read the file and the other for mapping. I've never used RFC and Java mapping, Can someone provide me a link or a solution for this?
Thanks,
Vishal

Hi,
You can do this using a UDF.
first let the source message contain first line and last line which you want to eliminate.
change the context of the Value to MT ..
start a for loop in UDF ignoring first & last line like
for(int i = 1; i< input.length() - 1; i++)  // here i = 1 & not zero  & input length is -1 so that first & last field eliminates
       //carry on string operation to separate name & value on delimeter space
String name = input<i>.subString(0,.... to the indexOf space);
//similar for value also....
now you have name & value
check for name == 0052
if(name == 0052)
  perform rfc lookup
else
