SampleProgram.java

Code for the simple J/Link example program presented in section 2.3 of the J/Link User Guide.

To compile or run this program, you need to make sure that JLink.jar is in the class path. You can do this by setting the CLASSPATH environment variable or by specifying the path to JLink.jar using the -classpath option on the command line. The examples below use the -classpath option. You can leave this out if your CLASSPATH environment variable includes the full path to JLink.jar. Consult your Java documentation or the J/Link User Guide for more information.

To run this program, go to a shell or DOS window and change to the directory in which SampleProgram.class resides. Then use a line like:

(Windows)
java -classpath ".;\path\to\JLink.jar" SampleProgram -linkmode launch -linkname "c:/program files/wolfram research/mathematica/5.1/mathkernel.exe"

(Unix)
java -classpath .:/path/to/JLink.jar SampleProgram -linkmode launch -linkname 'math -mathlink'

(Mac OS X from a terminal window)
java -classpath .:/path/to/JLink.jar SampleProgram -linkmode launch -linkname '"/Applications/Mathematica 5.1.app/Contents/MacOS/MathKernel" -mathlink'

If you wish to compile this program, use a line like this:

(Windows)
javac -classpath ".;\path\to\JLink.jar" SampleProgram.java

(Unix, or Mac OS X from a terminal window)
javac -classpath .:/path/to/JLink.jar SampleProgram.java
