JAXB 2.1 API is being loaded from the bootstrap……（cxf与java的包冲突）

今天在学cxf在web工程中开发webservice时，出现包冲突，其错误代码如下：
信息: Creating Service {http://service.css.ty.com/}MyFirstServiceHelloWorld from class com.ty.css.service.HelloWorldService
Exception in thread "main" java.lang.LinkageError: JAXB 2.1 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/E:/javaLib/cxf_all_jar/jaxb-impl-2.2.1.1.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.2 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.6.0/docs/guide/standards/)

解决办法如下：
在jdK目录下的jre/lib/中建立endorsed文件夹，然后将jaxb-api-2.2.1.jar包与jaxb-impl-2.2.1.1.jar包拷入endorsed文件夹中，并将%JDK_HOME%\jre\lib\endorsed加入classpath后解决

解决JAXB2.1和JDK1.6/6.0的问题

方案1：

1.8. Using JAX-WS 2.1 with JavaSE6

JavaSE6 ships with JAX-WS 2.0 API in rt.jar, which causes some trouble when you try to run applications that use JAX-WS 2.1 API. This document collects information about how to solve this issue. 1.8.1. Endorsed directory

One way to fix this is to copy jaxws-api.jar and jaxb-api.jar into JRE endorsed directory, which is $JAVA_HOME/lib/endorsed (or $JDK_HOME/jre/lib/endorsed)

Some application containers, such as Glassfish, modifies the location of the endorsed directory to a different place. From inside the JVM, you can check the current location by doing System.out.println(System.getProperty("java.endorsed.dirs"));

Obviously you still need other JAX-WS jars in your classpath.

Please do not put all the jars to the endorsed directory. This makes it impossible for JAX-WS RI to see other classes that it needs for its operation, such as servlet classes on the server-side, or Ant classes in the tool time. As those are not loaded by the bootstrap classloader, you'll get NoClassDefError on servlet/Ant classes.

方案2：

Support for JDK 1.6

Jbossws 2.0.1.GA is based on the jax-ws and jaxb versions 2.1. But JDK 1.6 ships jaxb 2.0 classes as part of the core distribution (rt.jar). So in order for the jboss jars to take precedent over the jdk supplied jars, we have to use the endorsed directory mechanism, as described here. The above link is for using jaxws ri 2.1, but we need jbossws 2.0.1. For that purpose copy the following 3 jars in to the jboss/lib/endorsed directory.

So assuming your jboss is setup in a directory /jboss and you have already installed jbossws 2.0.1 on top of it, Copy the following 3 files to /jboss/lib/endorsed.

• /jboss/server/default/lib/jboss-saaj.jar
• /jboss/server/default/lib/jboss-jaxws.jar
• /jboss/client/jaxb-api.jar

The jboss run script is already configured to add the /jboss/lib/endoresed directory to the list of endorsed directory. So jars in this directory will take precedence over rt.jar.
