java – 尝试调用CXF / SOAP Web服务时的LinkageError

我有一个项目(比如myproject),我在其中托管了一个CXF RESTful服务和CXF WS / SOAP服务,并在JBoss(6.0.0.FINAL)上运行. RESTful接口由我们所有内部系统使用,SOAP接口由第三方系统使用(作为回调接口)

以下网址工作正常.

> REST URL：http：// localhost：8080 / myproject / internal / someOperation(content-type：application / json和POST body)
> SOAP WSDL：http：// localhost：8080 / myproject / cbsoap？wsdl

现在我的问题是实际的SOAP调用不成功.我使用SOAPUI来尝试SOAP调用,但只是为了能够查询WSDL.我收到以下错误： –

javax.servlet.ServletException: Servlet execution threw an exception
    org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:67)

解决方法:

LinkageError是JBoss,通常是由你的应用程序打包JBoss认为限制的某些库的副本.这些通常是java.*和javax.*包中的东西.

看看你的堆栈跟踪,我猜测罪魁祸首是javax.activation.DataHandler.检查应用程序的捆绑JAR文件,确保它们中没有类似的东西.如果有,则删除它.

它可能不是javax.activation.DataHandler,但可能是它依赖的东西.
