Similar to OSGi, JIOPi(Java Interface-Oriented Programming initiative) is also a specification for building Java Module System .


  • Lightweight - only one small Jar file (less than 50k) needs to be added to the classpath
  • High compatibility - can be used in any Java project(J2SE,J2EE), or even an OSGi project
  • Good integration - can be integrated with nearly all mainstream Frameworks (Struts,Spring,Hibernate etc.. )
  • POJO compatibility - JIOPi Module is fully compatible with POJO Jar. It can be used in any other Java System without any modifications
  • Separate runtime environment - resolve dependency conflicts
  • Plain old method calling - so there is no runtime overhead
  • IoC style dependencies - easier to understand and use
  • Ignore the implementation details - call the APIs to access specified module directly
  • Assembly mode - a Module can be assembled by a assembly file
  • Replaceable assembly - use a module by provide a new assembly file
  • Smart upgrade - automatic upgrade module program to the latest compatible version , or you can specify a fixed version for stability
