\section bindings_binding_java_install How to install Simgrid-java
To use java with Simgrid you have to install some dependencies:
- \li Simgrid (see <a href="http://simgrid.gforge.inria.fr/simgrid/3.7/doc/install.html">install
+ \li Simgrid (see <a href="http://simgrid.gforge.inria.fr/simgrid/latest/doc/install.html">install
Simgrid</a>). You should set the SIMGRID_ROOT environment
variable to the path where you installed SimGrid.
- \li Java JDK packages, such as sun-java6-jdk (with libgcj10-dev or
-another version of gcj) or openjdk6. For maximal performance and
-scalability, use a coroutine-enabled JVM (see
-\ref bindings_binding_java_coroutines).
+ \li Java JDK packages, such as openjdk7 or sun-java6-jdk (with
+ libgcj10-dev or another version of gcj). For maximal performance

Then Download and install package Simgrid-java:
\verbatim

+If cmake complains that <b>jni could not be found</b>, you need to
+tell it where JNI header files are located. the following command
+should tell you:
+
+\verbatim
+$ locate jni.h
+/usr/lib/jvm/java-6-openjdk-amd64/include/jni.h
+/usr/lib/jvm/java-7-openjdk-amd64/include/jni.h
+\endverbatim
+
+If you have several version of jni installed (as in the example
+above), you need to check the version of java that is used by default
+on your machine (using javac -version), and pick the right one. Then
+set the JAVA_INCLUDE_PATH environment variable to the right path (note
+that we remove the filename jni.h from that path), and relaunch cmake.
+
+\verbatim
+$ export JAVA_INCLUDE_PATH=/usr/lib/jvm/java-6-openjdk-amd64/include/
+$ cmake .
+\endverbatim

To execute the examples you need to add the path where you installed
LD_LIBRARY_PATH.
\verbatim
-$ export SIMGRID_ROOT="$HOME/Install/simgrid/"
-$ export SIMGRID_JAVA_ROOT="$HOME/Install/simgrid-java"
-$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SIMGRID_ROOT/lib:$SIMGRID_JAVA_ROOT/java
+$ export SIMGRID_ROOT="$HOME/Install/simgrid/" # change it to the path where you installed the SimGrid library
+$ export SIMGRID_JAVA_ROOT="$HOME/Install/simgrid-java" # change it to the path where you installed the java bindings of SimGrid
+$ export LD_LIBRARY_PATH=${LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:}$SIMGRID_ROOT/lib:$SIMGRID_JAVA_ROOT/java
$ cd examples
$ java -cp .:../simgrid.jar basic/BasicTest platform.xml basic/basicDeployment.xml
\endverbatim

+If you want to make these settings permanent even after a reboot, you
