JavaZone-Code-Injection

Code for my presentation of code injection at JavaZone 2011

Get the code, run it and look for 'THE INJECTED CODE SAYS:' in its output.

= Getting the code = Point your browser to https://github.com/jakubholynet/JavaZone-Code-Injection/zipball/master and a ZIP archive download should start.

= Running the examples with Maven = I've been using Maven 2.2.1. cd /path/into/the/downloaded/folder/where/pom.xml/is

1. Java Proxy:
   mvn -P javaproxy test
2. Javassist:
   mvn -P javassist test
3. AspectJ:
   mvn -P aspectj test

= Running the examples manually =

• Get the dependencies described in pom.xml and their transitive dependencies
• Compile the sources
• Run them:
  *# Java Proxy:
  *## java -classpath <the dependencies listed below:/path/to/classes> iterate.jz2011.codeinjection.javaproxy.Main
  *# Javassist:
  *## java -classpath /path/to/javassist-3.14.0-GA.jar:/path/to/classes iterate.jz2011.codeinjection.javassist.JavassistInstrumenter
  *## java -classpath target/javassist:/path/to/classes iterate.jz2011.codeinjection.javassist.Main
  *# AspectJ:
  *## In aspectj-inject-build.xml define maven.plugin.classpath as described
  *## ant -f aspectj-inject-build.xml
  *## java -classpath "/path/to/classes:/path/to/aspectjrt-1.6.10.jar" iterate.jz2011.codeinjection.aspectj.Main
