System Requirements for parts I and II

To use the Java Binding Mechanism, the Caché JDBC Driver, and to complete the tutorial exercises, your Java application must meet the following requirements:

  • It must use Java version 1.7 or 1.8. The drivers and other files for 1.7 and 1.8 are in, respectively, <cachesys>\dev\java\lib\JDK17\ and <cachesys>\dev\java\lib\JDK18\.

  • When using the Java Binding Mechanism, both cachejdbc.jar and cachedb.jar must be on the application's class path.

  • When using strictly relational JDBC, cachejdbc.jar must be on the application's classpath.

For more information on these requirements, read Java Client Requirements in Using Java with Caché as well as the “Supported Java Technologies” section of the online InterSystems Supported Platforms document for this release.


In a standard Windows installation <cachesys> is C:\InterSystems\Cache. In a standard UNIX® or Linux installation it is /usr/cachesys.
