For a long time I use Smalltalk for analysis and reworking of data. ST/X is fast and offers the possibility to make executables. In order to write not every code by myself I’ve looked for a possibility to import data from excel to my PostgreSQL database. There was a good choice in the Java-world and with that the challenge to bring together the smalltalk world with the java world shows up. And here it is. Because of the work by Jan Vrany there is the possibility to use the library, written in Java from within ST/X. It works like a charm in my daily job and helps me to getting data from one world to the other without that much costs.
