Preparing to do OpenSAML 2 Development
If you wish to develop extensions to the OpenSAML 2 library these instructions will help you set up your developement environment.
First, if you are using the Sun JVM you MUST endorse the latest Xerces and Xalan.
Next, check out the libraries from the repositories listed below. Instructions for doing this in Eclipse can be found here.
For Java Development: java-xmltooling, java-openws, java-opensaml2
For C++ Development: cpp-xmltooling, cpp-opensaml2
After that, it's just Java development as normal.
