reading the following articles (tutorials) i tried to use the function toIRIString() (in java.net.URI) but i cannot seem to find it (in my current jre6.18)
i tried to get access and downloaded the lateset source code (jdk6/trunc) but cannot find it there either
Are the tutorials wrong or is it placed in another library? thanks!
