在SSH jdk6.0 Tomcat6.0环境中使用CXF 运行时报如下错误

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.cxf.wsdl.WSDLManager' defined in URL [jar:file:/E:/workSpace/T82A/WebRoot/WEB-INF/lib/cxf/cxf-2.1.3.jar!/META-INF/cxf/cxf.fixml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.cxf.wsdl11.WSDLManagerImpl]: Constructor threw exception; nested exception is java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/E:/workSpace/T82A/WebRoot/WEB-INF/lib/cxf/jaxb-impl-2.1.7.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API.

按照网上看说，在jdk1.6.0_05\jre\lib\下新建endorsed文件夹，放入jaxb-api.jar还是没有效果，经过我的仔细阅读E文，纠正这个错误，如果是Tomcat 5.5,则新建文件路径为“Tomcat 5.5\common\endorsed”，如果是Tomcat 6.0，则新建路径为“Tomcat 6.0\endorsed”。不是在jdk1.6.0_05\jre\lib\

对于找一个jaxb-api.jar的包（比如从netbeans目录下搜索一下），复制到endorsed目录下去.

自己测试:

         jre必须是1.6, tomcat5.5的jdk可以是jdk1.5,  jdk和jre下面新建endorsed文件夹,并放入jaxb-api.jar和jaxws-api.jar是没用的, 必须把这两个jar包放入"tomcat5.5\common\endorsed"(没有这个文件夹则新建,如果是 tomcat6.0, 则放在"Tomcat6.0\endorsed"), 特把两个jar共享..

 

         测试内容: 自制webservices客户端访问jax-ws的webservices服务端

         测试环境: myeclipse6.5  tomcat5.5  jre1.6  jdk1.5(可以全是1.6)
