#first export JAVA_HOME so the java build can find Java. Use path that makes since on your system. $ export JAVA_HOME=/usr/lib/jvm/java-1.8.0/ #build code using SCons of the auto_build script $ scons BUILD_JAVA=1 #or $ auto_build.py build_linux_secured_with_java
Now run the samples. # Change to the output directories. $cd out/linux/x86_64/release/java # run the samples $ java -Djava.library.path=.. -jar simplerserver.jar $ java -Djava.library.path=.. -jar simpleclient.jar If the samples crash instantly saying they cannot find a library check your java.library.path make sure it is pointing to the directory that contains the libocstack-jni.so file.

The Java-themed build isn't actually very complicated to /run/ (it may be complicated to understand all of what's happening, but that's a different story). If you've never built it before, you need to get the host system dependencies installed, which is a one-time job and documented on the wiki, and the first build will stop a couple of times for you to check out from git trees of external projects because developers felt it wasn't safe to automatically check those out; all the other dependencies are automatically downloaded. but besides that one-time cost, the build is no more complicated on a Linux host than: 1. make sure JAVA_HOME is set 2. ./build.sh build_linux_secured_with_java or ./build.sh build_linux_unsecured_with_java depending on which one you want.
