Jasper requires at least Java 1.5 to run. Except under Windows the full development kit, not just the JRE, is needed. c [PM] 4.3 irrelevant these days: Jasper does not work with Visual J++ or Visual Café. Unless indicated otherwise, you can download the JDK from http://java.sun.com.
Except where indicated, Jasper is supported for Java 1.5 or later.
For some platforms, Jasper is only supported under the following conditions:
On OS X you can either use the legacy Java 6 from Apple, or Java 7 or later from http://java.sun.com.
On OS X, embedding Java 7 or later in SICStus, e.g. by using
library(jasper), may fail, possibly with a dialog about the
need for a Java SE 6 runtime. This seems to be caused by missing
information in the section ‘JVMCapabilities’ of the file
Info.plist in the Java installation. As of April 2014 there
were no official information from Oracle about this but several
suggested workaround can be found on the net.
