plsql修改oracle字符集:我的网站apaceh2.0.55+tomcat4.0+JDK1.3为什么不成功

我的网站我进行了apache和tomcat的conf和server.xml的修改
在apache/httpd.conf 中加入

LoadModule jk_module modules/mod_jk.so
JkWorkersFile 'D:\Apache2\conf\workers.properties'
JkMount /servlet/* ajp13
JkMount /*.jsp ajp13

在tomcat/server.xml 中加入

<Service name="Tomcat-Apache">

<Connector className="org.apache.catalina.connector.warp.WarpConnector"
port="8008" minProcessors="5" maxProcessors="75"
enableLookups="true" appBase="webapps"
acceptCount="10" debug="0"/>

<Engine className="org.apache.catalina.connector.warp.WarpEngine"
name="Apache" debug="0">

<Logger className="org.apache.catalina.logger.FileLogger"
prefix="apache_log." suffix=".txt"
timestamp="true"/>

<Realm className="org.apache.catalina.realm.MemoryRealm" />
<Host name="www.wmcn.com" debug="0" appBase="d:/website" unpackWARs="true">
<Context path="/" docBase="d:/website" debug="0" reloadable="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="d:/tomcat_logs" suffix=".txt"
timestamp="true"/>
</Context> </Host>
</Engine>

</Service>
当我启动的时候就会出现以下的问题，这是为什么？
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

希望大家能帮帮我
