To use it in B4J we have to copy the sajdbc4.jar & jodbc4.jar to our additional libraries folder. Those files are provided with SQL Anywhere client installation.

If all steps mentioned before are done, then we are ready to write our first application in B4J to connect and query a SQL Anywhere Database. For the purpose of our example we will use the sample database provided with SQL Anywhere 16. Continue reading
