When loaded, this resource installs a set of predicates whichĪre mapped onto Java-methods and when invoked, converts the PrologĪrguments to the corresponding Java-types before calling the Java Java methods are called from Prolog much in the same way as C functionsĪre called (see section Calling C from Prolog) by creating a foreign The rest of this chapter assumes that there is a Java installation with Sun's Java Runtime Environment provides a minimal executionĮnviroment for running Java code. If your Java installation does not support the JNI,

Even though the JNI is intended as a standard, not all The JNI, it is necessary that the Java VM which is to be used has The JNI is a native interface standard developed by The low-level interface uses the JNI (Java Native Interface) to call Cįunctions from Java.

Recapitulation of the information in the chapter section Mixing C and Prolog. Note: Some of the information in this chapter is a Visible to the programmer, but it is useful to have a picture of how the SICStus Development System, it is loaded as any other foreign resource, When the Java Runtime System is loaded into the When the Java Runtime System is used asĪ top-level application, the SICStus runtime kernel is loaded into Jasper can be operated in two different ways, depending on whichĮmulator is used as top-level application the Java Runtime System or

Predicates and provide automatic conversion of arguments. The Prolog part is designed as anĮxtension to the foreign language interface, which means thatįoreign/3 declarations are used to map Java-methods on Prolog The Java-side of the interfaceĬonstists of a Java package ( jasper) containing classes Jasper is a bi-directional interface between programs written in Go to the first, previous, next, last section, table of contents.
