FAQ

1、Axis2中出现的Unexpected EOF in prolog问题

开发环境：JDK1.6.0，Geronimo 2.1.1( 含Axis2 )

问题描述：按照http://cwiki.apache.org/GMOxDOC21/developing-a-simple-calculator-web-service.html上的教程构建jax-ws calculator这个web service，可部署到Geronimo 2.1.1后，在index.jsp上输入3和4，然后点击=转到result.jsp后，Geronimo控制台上出现如下错误：

18:54:35,406 ERROR [Axis2WebServiceContainer] Exception occurred while trying to invoke service method doService()

org.apache.axis2.AxisFault: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog

at [row,col {unknown-source}]: [1,0]

        at org.apache.axis2.AxisFault.makeFault(AxisFault.java:417)

解决方案：很简单，关闭你的杀毒软件如卡巴斯基(Kaspersky)就行了，Windows防火墙不用关。另外，如果卡巴斯基是开着的，在Geronimo 1.1.1 + Axis2 1.2里部署了Web服务后，访问时也会出现类似于上面的问题。

P.S. ：在含Axis2的Geronimo里部署Web服务后，如果发现自动生成的WSDL文件中的端口的地址不对，如IP地址部分编程了192.168.30.1，则很有可能是因为安装了VMware后出现的虚拟网络连接导致的，禁用这些虚拟网络连接即可。

2、将ws.aar文件复制到<Tomcat安装目录>\webapps\axis2\WEB-INF\services目录中，启动Tomcat后Tomcat报错

解决：这是中文问题，删掉services.xml中的中文即可。要想在services.xml中加中文，需要将编码设为UTF-8或GBK。
