使用Xfire发布WebService接口遇到的问题：

问题一：

log4j:WARN No appenders could be found for logger (org.codehaus.xfire.transport.DefaultTransportManager).
log4j:WARN Please initialize the log4j system properly.
org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Could not read XML stream.. Nested exception is com.ctc.wstx.exc.WstxParsingException: Expected a text token, got START_ELEMENT.

为什么呢？    经过漫长的调试发现，发现我的webservice服务端自定义对象有问题，在自定义对象中有字段的类型为char，就是因为对char类型无法传递导致这个错，但不一定报这个错的就一定和我这次的原因一样
