Advantages and disadvantages of using Java vs. LEI to import data from DB2 into Domimo R6

We are trying to assess the advantages/disadvantages of using Java versus Lotus Enterprise Integration (LEI) to import data from DB2 into Domino R6. Both databases (DB2 and Domino) are running on separate iSeries servers. The DB2 database houses company data. The Domino database R6 is for employee information. I am aware that LEI for R6 was only recently released for iSeries with R6.0.1. Thank you in advance for your thoughts and opinions.
I think you'll find an LEI activity (replication or virtual fields, probably, depending on your requirements) will be both easier to implement because no coding is needed -- you just fill in forms -- and it's faster to execute. The speed comes about because:
  • LEI uses native database drivers instead of ODBC or JDBC.
  • LEI accesses the Notes C API directly instead of going through a Java front-end.
  • LEI is written in C++ to run in your processor's machine language, whereas even compiled Java is "virtualized" and therefore slower.
