Issue/Introduction
Error thrown when loading terrJava, parallel or sjdbc package: "Error in .JavaStart() : can't load terrJava: JAVA_HOME not set".
Environment
All supported environments
Resolution
To use any of the following packages in TERR:
parallel
sjdbc
terrJava
you must have a bit-matching (32-bit or 64-bit) version of the Java Runtime Environment (JRE) installed. After you have installed a bit-matching version of Java, also make certain to set the JAVA_HOME environment variable on your machine to point to the installation path to your Java installation. Once this is done, restart TERR and load the library again. Alternatively, you can also set the JAVA_HOME environment variable within the TERR console before you load the library, using a call similar to the following:
Sys.setenv(JAVA_HOME="C:/Program Files/Java/jdk1.7.0_45")
Once this has been done, try to load the library again.
