Getting MDM Result Set of a table into MS Excel using MDM 5.5 Java API’s and JXL API.

The complete process can be divided into two steps:


1) Establishing connection with the MDM Server and getting the Result Set of a table into a WebDynpro context node.
2) Putting the data from a Context Node into a MS Excel sheet using JXL api.


Reason for using JXL API and not the Download to excel functionality.


SAP provides out-of-box Download to excel functionality which can be used in any application.
But the only problem that I faced in using them is that, if your table data contains any special characters like ‘&’
(like the particular case in MDM where I was working), then this will throw an exception.

The reason for this is because the table data is first converted to XML format and then into an Excel sheet and in the XML
data cannot have any such special charaters(the only reason that I could find).

In such a situation it was easier to use JXL api for the same. Moreover it has the advantage that you can have the data in any
Format , Font , Color etc.
