错误信息如下：

500 Servlet Exception
WEB-INF/web.xml:20: `com.sohu.blogSuggest.SuggestConf' is not a known servlet.
Servlets belong in the classpath, often in WEB-INF/classes.

Resin-3.0.24 (built Thu, 16 Aug 2007 09:38:29 PDT)

com.sohu.blogSuggest.SuggestConf在suggest.jar里面，该包放在了/search/odin/resin/sugg/tag/WEB-INF/lib下面

web.xml（/search/odin/resin/sugg/tag/WEB-INF/web.xml）内容如下：
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

Sohu blog suggestion

<context-param>
    <param-name>suggest.propfile</param-name>
    <param-value>/WEB-INF/suggest.properties</param-value>
</context-param>

<context-param>
    <param-name>suggest.web.propfile</param-name>
    <param-value>../conf/websuggest.conf</param-value>
</context-param>

<!-- Suggestion Servlet Configuration -->
<servlet>
    <servlet-name>suggest.configuration</servlet-name>
    <servlet-class>com.sohu.blogSuggest.SuggestConf</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
 <!-- Charset Filter Configuration -->
 <filter>
   <filter-name>charsetfilter</filter-name>
   <filter-class>com.sohu.suggestion.CharsetFilter</filter-class>
 </filter>
 <!-- Charset Filter Mapping -->
 <filter-mapping>
   <filter-name>charsetfilter</filter-name>
    <url-pattern>/json.jsp</url-pattern>
 </filter-mapping>

将suggest.jar解压后放置在/search/odin/resin/sugg/tag/WEB-INF/classes下面也不行

将电脑JDK1.8->1.6.0_45也不行，中间尝试更改XML文件内容等等都不行

【解决】Preference->Java->Compiler下将版本1.8改为1.6

吐槽：愚蠢的错误！！！！！搞了两天才尝试发现~~
