Jar Versions : jena-iri : 1.0.2 , java-rdfa : 0.4

Thanks.

Answer 1

我有理由，我已经尝试了java-rdfa版本0.4和0.5快照，但它们都引用了com.hp.hpl.jena.iri.IRIFactory ，但是在当前的包装中，IRIFactory被移动到包org.apache.jena.iri.IRIFactory 。

Answer 2

com/hp/hpl/jena/iri/IRIFactory class is not in any of the JARs specified in the class path.

To find the whether the class IRIFactory is in any of the jar files in the CLASS_PATH 1) In windows extract each jar file and check for the class name 2) In linux use "jar -tvf [jar-file-name] |grep "IRIFactory"

If none of the jar contains the class file, add the correct jar in the class path.
