在SSH jdk6.0 Tomcat6.0環境中使用CXF 運作時報如下錯誤 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.

 --------------------------------------------- 以上是轉載,以下是測試 ---------------------------------------------------------

自己測試:

         jre必須是1.6, tomcat5.5的jdk可以是jdk1.5,  jdk和jre下面建立endorsed檔案夾,并放入jaxb-api.jar和jaxws-api.jar是沒用的, 必須把這兩個jar包放入"tomcat5.5\common\endorsed"(沒有這個檔案夾則建立,如果是 tomcat6.0, 則放在"Tomcat6.0\endorsed"), 特把兩個jar共享..

         測試内容: 自制webservices用戶端通路jax-ws的webservices服務端

         測試環境: myeclipse6.5  tomcat5.5  jre1.6  jdk1.5(可以全是1.6)
