VTK/Tutorials/JavaEnvironmentSetup

• Download and install the sun JDK: http://java.sun.com/javase/downloads/widget/jdk6.jsp

(Throughout the following we will assume it is installed in /opt/java, though you can install it wherever you please)

• Add /opt/java/jre/lib/i386 and /opt/java/jre/lib/i386/xawt to LD_LIBRARY_PATH as well as the VTK libraries (in ~/.bashrc)

• Add /opt/java/bin to your PATH

• In your ~/.bashrc, add

export JAVA_HOME=/opt/java

• The Java relevant paths that CMake should find are:

JAVA_AWT_INCLUDE_PATH            /opt/java/include
JAVA_AWT_LIBRARY                 /opt/java/jre/lib/i386/libjawt.so
JAVA_INCLUDE_PATH                /opt/java/include
JAVA_INCLUDE_PATH2               /opt/java/include/linux
JAVA_JVM_LIBRARY                 /opt/java/jre/lib/i386/client/libjvm.so
Java_JAR_EXECUTABLE              /opt/java/bin/jar
Java_JAVAC_EXECUTABLE            /opt/java/bin/javac
Java_JAVA_EXECUTABLE             /opt/java/bin/java

• You can now run VTK Java scripts as follows:

javac -cp ".:/home/doriad/bin/VTK/bin/vtk.jar" ClassName.java
java  -cp ".:/home/doriad/bin/VTK/bin/vtk.jar" ClassName

Fedora specific instructions

• yum install java-devel
