NoClassDefFoundError: com/sun/xml/internal/bind/DatatypeConverterImpl using knopfletfish

Question

I am new to ogsi and when I run the bundle in the knopfletfish framework, I obtain this error:

I don´t know why is happening this, I have referenced all jabxb jars, and maybe is important saying that it happened since I changed jdk8 by jdk7 in order to work with another jdk7 bundles.

This is the class where the exception is marked:

Answer 1

我认为您需要将com.sun软件包添加到引导委托中。

org.osgi.framework.bootdelegation=com.sun.*

Answer 2

use Wrapper classes in Bean with getter and setter. don't use primitive data type in bean class with getter and setter.

wrong: int i;
right: Integer i;
