# Sample code to use Byteman and JBoss



This repo contains an example to show how to use Byteman in JBoss to inspect all object injected into the WebSession.

The Byteman Helper checks if object is Serialiable or not.



## First compile ByteMan Helper  



```

  cd ExtractGrape

  mvn clean package

```



## Second compile sample application



```

  cd helloworld

  mvn clean package

```



## Runtime



Copy the War file to the JBoss `deployement` directory



Modify `standalone.conf` like this 



```

JBOSS_MODULES_SYSTEM_PKGS="org.jboss.byteman,net.a.g"

BYTEMAN_JAR=${MAVEN_REPO}/org/jboss/byteman/byteman/3.0.3/byteman-3.0.3.jar

BYTEMAN_CONF=./ExtractGrape



JAVA_OPTS="${JAVA_OPTS} -Dorg.jboss.byteman.verbose -Dorg.jboss.byteman.transform.all -javaagent:${BYTEMAN_JAR}=script:${BYTEMAN_CONF}/sessionintrospection.btm,sys:${BYTEMAN_CONF}/target/ExtractGrape-0.0.1-SNAPSHOT-jar-with-dependencies.jar,policy:true,boot:${BYTEMAN_JAR},listener:true"

```



## Result 



You should get an output like this when you call 



```
