How to change IJC’s Java

Edit etc/instantjchem.conf in the Instant JChem’s directory. Append the following line to the end of the file:

jdkhome=<JAVAHOME>

where <JAVAHOME> is the absolute path of the home directory of the new Java. E.g.:

jdkhome=/usr/java/jdk1.5.0_10

Any other lines that starts with jdkhome= has to be taken into comment (by placing a # character on the beginning of the line).
