might be JavaWebStart(JWS)kit is not installed ... and check
with SAP-Basis people...

basically XI is a J2EEengine and Jdk is needed ..

i have already installed javaweb tool kit. but it need  
some little configuration.

a) Remove Contexts: - remove all higher level contents of 
the source level message in order to map with the target 
message field. So you can get the node contexts removal.

b) Split by value: - Insert Context change for an element 
split by value is some as counter part of remove context. 
Here instead of delivering the context you can insert a 
context change in the source value queue.
c) Collapse contexts: - Copies first values of the all 
contexts to one context empty context are replaced by empty 
string.
d) Copy Value: - How many ever times I occur I am copied 
just once". This is not a node function but I am explaining 
it as it is used very frequently in real-time. Let us take 
an instance of material group, which can occur as many 
times as the item node. But since we are mapping it to the 
header in the target node I just want to copy the first 
occurrence of material group and map it to the header node. 
CopyValue exactly does that.
e) Create if: - It will create a target node or element 
based on some condition.
f) Exists: - Function to determine whether a particular 
source field exists in instance to be processed. If it does 
it gives true or else false.
g) Use one as many.
h) Replace value: - Replace the value I with the value that 
you desired in the dialogue for function properties.
i) Sort: - Sorts all values of the multiply occurring 
inbound field with in the existing or set context.

UDF are are user defined functions may be simple or advance.
You have to create new UDF at message mapping editor. You 
can create UDF according to your requirement in order to 
fulfill your requirement if it is not avaialble in standard 
functions.

It will take two inputs...In result  first node values and
second node structure will come to Target node

FormatByExample has 2 input
1..input 1 : value is taken from this
2..input 2 : context is changed from this to generate target
value

Flag is not a standard term. For you case it would mean the 
way to distinguish the records in the database. This may 
help you to pick up certain records and change the status 
of this Flag so that the same message is not read again by 
XI.

flag is not the standarised term in Xi. as we update data in
database we use this term so that we know whether the data
is being  transfered.

The UPDATE statement allows updating the values of selected 
columns of rows of a database table.

by update statement you update your database table values 
and for the next time it will not select the previous 
values which is updated ..otherwise you will not be able to 
find which values are selected in the previous selection
