When you want to access a DB2 database from Java, you usually need IBM’s JDBC driver for DB2. In the past, I (and some other people I know) always had trouble in finding out where to download the recent version of the driver. To solve this issue once and for all, I just took a deep dive into IBM’s website. There I found the following page, which seems to be ultimate resource to downloading DB2′s JDBC driver: https://www-304.ibm.com/support/docview.wss?uid=swg21363866.
