Versions

ExtVal release numbers are directly linked to the JSF version they're compatible with.

• ExtVal 1.1.x is compatible with JSF 1.1.x
• ExtVal 1.2.x is compatible with JSF 1.2.x
• ExtVal 2.0.x is compatible with JSF 2.0.x

Setup

Required steps:

1. Download the required ExtVal jar-files. (As an alternative, you can of course checkout the Source Code and build ExtVal yourself.) Basically you just have to choose the validation module(s) you would like to use and include it/them as well as the core of ExtVal in your JSF application. Currently you need at least:
   • myfaces-extval-core-*.jar
   • Optional: The validation module you would like to use (e.g.: myfaces-extval-property-validation-*.jar and/or myfaces-extval-bean-validation-*.jar and/or your own implementation)
   • Optional: Furthermore, you might need a component support module for the component library you are using. Or you might need the generic component support module. E.g. ICEfaces as well as RichFaces use some special tricks. Therefore, you need the generic component support module. However, there are also component libs which don't need an additional support module. Esp. with JSF 2 you should test if you really need a component support module. If something renders differently, you just have to include the generic component support module.
2. Add the ExtVal jar-files to your classpath.
3. Use the annotations.

That's it!
