我正在使用JAX-WS来调用SOAP Web服务。解析SOAP响应时会遇到异常。我的SOAP客户端是一个JAR，它运行在Weblogic服务器中部署的另一个Web应用程序中。
javax.xml.soap.SOAPException: Error parsing envelope: most likely due to an invalid SOAP message.: Unexpected EOF in prolog
Caused by: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog at [row,col {unknown-source}]: [1,0]

令人惊讶的是，我能够在日志中打印SOAP响应。
