关于tomcat的ssl配置的问题

Question

已经有server.keystore了，而且运行https://localhost:8443也可以出来页面,可是在log中却有下列异常,这是为什么呢?server.xml中相关配置如下:
 <Connector enableLookups="true" keystoreFile="C:\Documents and Settings\Zhiliang\server.keystore" keystorePass="changeit" port="8443" redirectPort="-1" scheme="https" sslProtocol="TLS" algorithm="SunX509" clientauth="false" keypass="changeit" keystore="C:\\.keystore" keytype="JKS" protocol="TLS" secure="true">
      <Factory className="org.apache.coyote.tomcat5.CoyoteServerSocketFactory" keystoreFile="C:\Documents and Settings\Zhiliang\server.keystore"/>
    </Connector>异常如下:

还有一个比较菜的问题:在server.xml中keystore出现了三次,分别有什么不同呢?我是用administration来配置的.

Answer 1

我删除第二个keystore,出现如下异常:
