虚线以下内容是网络上找到的他人的方法，自己面临Unexpected character '>' (code 62) expected '=' 时尝试使用此法，但却不见效，后来发现，每当出现此错误，重新启动（1）MyEclipse 或 (2) Tomcat 或 (3) 计算机（ Computer）可解决此问题。

------------------------------------------------------

声明：第一次开发WebService，第一次使用XFire，WebService方面的新手

目的：分享经验、备忘

时间：2008-01-22

错误说明：在调用WebService的时候报错：

org.codehaus.xfire.fault.XFireFault: Unexpected character '>' (code 62) expected '='

org.codehaus.xfire.fault.XFireFault: Unexpected character '>' (code 62) expected '='

解决方案：在webService应用的web.xml中加入：

<filter>
<filter-name>CompressingFilter</filter-name>
<filter-class>
com.planetj.servlet.filter.compression.CompressingFilter
</filter-class>
<init-param>
<param-name>debug</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>statsEnabled</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CompressingFilter</filter-name>
<url-pattern>/services/*</url-pattern>
</filter-mapping>

<filter>
    <filter-name>CompressingFilter</filter-name>
    <filter-class>
      com.planetj.servlet.filter.compression.CompressingFilter
    </filter-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>false</param-value>
    </init-param>
    <init-param>
      <param-name>statsEnabled</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CompressingFilter</filter-name>
    <url-pattern>/services/*</url-pattern>
  </filter-mapping>

详细说明:

开发环境：

服务器：Tomcat5.0

JDK： JDK1.4.2

IDE： MyEclicpse6.0.0 GA+Eclipse3.3

其他： XFire1.2.6

开发简要说明（代码就是SayHello，这里不再说明）：

1、通过MyEclipse建立Web Service Project

2、通过MyEclipse新增WebService：

service name:SayAny

Service Interface: ISayAny

Service Impl. class: ISayAnyImpl

生成的Web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>XFireServlet</servlet-name>
<servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <servlet> 
    <servlet-name>XFireServlet</servlet-name>
    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

services.xml内容如下：（新手说明：在项目下与WebRoot同级目录下，myEclipse自动生成一个WebServices目录，services.xml在此目录中）

<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>SayAny</name>
<serviceClass>com.jiang.service.ISayAny</serviceClass>
<implementationClass>com.jiang.service.SayAnyImpl</implementationClass>
<style>wrapped</style>
<use>literal</use>
<scope>application</scope>
</service>
</beans>

<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>SayAny</name>
<serviceClass>com.jiang.service.ISayAny</serviceClass>
<implementationClass>com.jiang.service.SayAnyImpl</implementationClass>
<style>wrapped</style>
<use>literal</use>
<scope>application</scope>
</service>
</beans>

3、直接通过MyEclipse发布到Tomcat上；

4、访问http://localhost/studyWebService/services/SayAny?wsdl可以成功看到一个XML内容，里面内容不在此说明

5、编写测试程序，main方法如下：

public static void main(String[] args) {
String serviceURL = "http://localhost/studyWebService/services/SayAny";
String datas = "";
//service
Service serviceModel = new ObjectServiceFactory().create(
ISayAny.class, null, "", null);
XFireProxyFactory serviceFactory = new XFireProxyFactory();
try {
ISayAny service = (ISayAny) serviceFactory.create(
serviceModel, serviceURL);
Client client = ((XFireProxy) Proxy.getInvocationHandler(service)).getClient();
client.setProperty(CommonsHttpMessageSender.GZIP_ENABLED,
Boolean.TRUE);
client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "0");
datas = service.sayHello("jiang shan");
System.out.println(datas);
} catch (Exception e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
    String serviceURL = "http://localhost/studyWebService/services/SayAny";

    String datas = "";
    //service
    Service serviceModel = new ObjectServiceFactory().create(
        ISayAny.class, null, "", null);

    XFireProxyFactory serviceFactory = new XFireProxyFactory();
    try {
      ISayAny service = (ISayAny) serviceFactory.create(
          serviceModel, serviceURL);
      Client client = ((XFireProxy) Proxy.getInvocationHandler(service)).getClient();
      client.setProperty(CommonsHttpMessageSender.GZIP_ENABLED,
          Boolean.TRUE);
      client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "0");
      datas = service.sayHello("jiang shan");
      System.out.println(datas);

    } catch (Exception e) {
      e.printStackTrace();
    }
  }

WebServer获得相应，但在

datas = service.sayHello("jiang shan");

datas = service.sayHello("jiang shan");

报错：

错误如下：

解决方案本文上面所说：加入pjl-comp-filter-1.4.6.jar,并在Web.xml中配置filter即可。

出错原因:这句有问题：

client.setProperty(CommonsHttpMessageSender.GZIP_ENABLED,Boolean.TRUE);

client.setProperty(CommonsHttpMessageSender.GZIP_ENABLED,Boolean.TRUE);

客户端调用时设置了GZIP参数，但Server端没有用GZIP过滤文件！
