On my Windows installation of DB2, I have the following directory

C:\Program Files\IBM\SQLLIB\java

Open in new window

In that directory, I have the following 2 files (I assume to be used for JDBC)


Open in new window

What is the difference between the two files, when do you use db2jcc, and when do you use db2jcc4

    these are two versions that correspond to two versions of the jdbc api

    i think it is safe for you to go with db2jcc4.jar
