Following is the sample schema I used to try to generate the JAXB classes. What I noticed is that when I have a string type with enumerations, for instance, in my case the stepType, with values starting with a numeral, JAXB does not generate a separate enum class say StepType class. It works fine, when I use only alphabets for the valu...
String s = UUID.randomUUID().toString(); return s.substring(0,8) + s.substring(9,13) + s.substring(14,18) + s.substring(19,23) + s.substring(24); I use JDK1.5's UUID, but it uses too much time when I connect/disconnect from the net. I think the UUID may want to access some net. Can anybody help me? ...

This question has always bothered me. And the NetBeans wiki does not say anything about that... Besides, JDK 1.5 will complete the End of Life process very soon and 1.6 has been around for quite a while. So why do they still use version 1.5 even if 1.6 is available on all Netbeans-supported platforms? ...
