Hi Jean-Louis,

Thanks for presenting this. I have not had time to look at it properly but it looks very interesting. I did download and build your git tree and install the resulting zip (the zip file in the git repo was corrupt). I followed the instructions to modify and run scripts/bytemapPkg.sh but it failed with the following exception

[adinn@zenade bytemanPkg]$ $PWD/scripts/bytemanpkg.sh

So, it looks like I don't have some of the javafx classes installed. Any idea what I need to do to obtain them?

Hello Andrew,

First you need a JRE/JDK 1.7.0

the jfx classes are in JRE_HOME/lib/jfxrt.jar, it must be added to the classpath in the script :bytemanpkg.sh

in fact the JAVA_HOME must point to JRE_HOME. I will correct it.

######## These two environnement Variables must be adapted #########
###
JAVA_HOME=/opt/jdk1.7.0_40/jre
## workspace directory must be created before launching thi script
workspace=/opt/eclipse/workspace/workspaceBM
#######################################################

if [[ ! -d $workspace ]]; then
    echo "the workspace : $workspace doesn't exist. Please create the directory or adapt the variable"
    exit 1
fi

#root=/opt/bytemanPkg
root=`dirname $0`/..
echo root=$root
CLASSPATH=$root/bytemanPkg.jar
CLASSPATH=$CLASSPATH:$root/config
CLASSPATH=$CLASSPATH:$root/lib/jsch-0.1.49.jar
CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/jfxrt.jar
CLASSPATH=$CLASSPATH:$root/lib/antlr-runtime-4.1.jar
CLASSPATH=$CLASSPATH:$root/lib/bytemancheck.jar
CLASSPATH=$CLASSPATH:$root/lib/jfxmessagebox-1.1.0.jar
$JAVA_HOME/bin/java  -Dprism.order=es2,j2d -cp $CLASSPATH -Droot=$root -Dworkspace=$workspace -Xms128M -Xmx128M jlp.byteman.packager.Packager

I will soon deliver a new version, that integrated your "dynamic" instrumentation ( bminstall, bmsubmit) as remote actions. They run perfectly. I need to write a little doc about them.

I will also add in a second time, a tool for charting csv files produted by the custom rules. This tool is based on JFeeChart. ( i have to extract it from another personal application).

Byteman is a great tool !, really

Thank Andrew.

Ok, I just commented out the line above because my JAVA_HOME was already set to point to a JDK1.7 SDK root i.e. not to the underlying jre tree (I suspect that most developers will have a similar setup).

However, I realise that there is also a further problem. I don't have JavaFX jar in my jre/lib direcory. That's because I am using OpenJDK and JavaFX is an Oracle proprietary extension to Java.

I don't know much about how JavaFX has been built. Does the code in the JavaFX jar also require native library code in the jre tree? Does it require any Oracle-properietary JVM extensions (i.e. have they made it impossible to use it on OpenJDK?).

Hi Andrew,

Yes i use Oracle JDK.

There is also an OpenJFX with OpenJDK, but i have not tested.

https://wiki.openjdk.java.net/display/OpenJFX/Main

The faster solution is to try with an Oracle JDK.
