[摘要]:java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from vfszip:/F:/JavaEmt/JBoss/lib/jaxb-impl.jar/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader.

在Eclipse中启动JBoss出现如下错误:

[原因]:
jboss-5.0.1.GA所用的jaxws和jaxb版本为2.1，而JDK1.6.0_03的是JAXB 2.0 和 JAX-WS 2.0更新。加载的是jdk的2.0版本的jaxws和jaxb，而jboss需要的是2.1版本的jaxws和jaxb。
[解决]:
方法1:
You probably are using an older version of Java 1.6. Download the latest available update of Java 1.6 from the Sun site and use that with JBoss.
更新到jdk1.6u11+即可。
方法2:
采用"授权标准覆盖机制"(Endorsed Standards Override Mechanism : http://java.sun.com/j2se/1.5.0/docs/guide/standards/)。
操作如下:
a.新建目录:$JDK_HOME/jre/lib/endorsed
b.将JBoss中2.1版的jaxb-api.jar和jaxws-api.jar复制到endorsed目录，则会完成对JDK的jaxb和jaxws api的覆盖。
