Access restriction:the type QName isn't accessible due to restriction on required library

There ' s another solution that also works. I found it on the This forum:

1. Go to the Build Path settings in the project properties.
2. Remove the JRE System Library
3. Add it back; Select "Add Library" and select the JRE System library. The default worked for me.

This works because you has multiple classes in different jar files. Removing and re-adding the JRE Lib would make the right classes be first. If you want a fundamental solution make sure you exclude the jar files with the same classes.
