尝试调用CXF/SOAP Web服务时出现LinkageError

Question

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体)

• 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)

Answer 1

LinkageErrorJBoss通常是由你的应用程序包装自己的JBoss认为限制的某些库的副本引起的.这些通常是java.*和javax.*包中的东西.

看看你的筹码追踪,我猜是罪魁祸首javax.activation.DataHandler.检查应用程序的捆绑JAR文件,确保其中没有类似的东西.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.
