The Java libraries integrate well with Eclipse, with auto-complete working out of the box.
Building the
...
Libraries (Linux)
- Setup the JAVA_HOME environment variable. The
javaexecutable is supposed to be found in$JAVA_HOME/bin/java - Setup the ROOT environment:
source <wherever you installed ROOT>/bin/thisroot.sh - Cd to the javaROOT directory.
- Run
make OSTYPE=linux-gnu all. - Tell the linker where to find the new shared objects. E.g. if running the example "C++", calling export LD_LIBRARY_PATH:$LD_LIBRARY_PATH:. is necessary for the program to run.
- Running the Java programs requires the classpath to be set approriately, e.g. java -cp ../../jar/javaROOT.jar:../../jar/freehep-physics-2.1.jar:. Test.
- If there are any problems with network exceptions on the LCSIM example, it is due to proxy servers: set these when Java is run by adding -Dhttp.proxyHost=<hostname> -Dhttp.proxyPort=<hostport> in the call to Java.
Building the

Libraries (Windows)
- Ensure the %ROOT_SYS% and %JDK_HOME% environment variables are set (go to System Properties (WinKey+Break), Advanced, Environment Variables) to the root folders of ROOT and the JDK respectively.
- Run a Visual Studio Command Prompt.
- Cd to the javaROOT root folder.
- Run mingw32-make all.
- Running the Java programs requires the classpath to be set approriately, e.g. java -cp ../../jar/javaROOT.jar:../../jar/freehep-physics-2.1.jar:. Test.
