[해결방법]

톰캣설치서버/conf/server.xml에 가서 secretRequired="false"을 추가해주면 된다 ( default가 true임 )

ㅇ변경전

<Connector protocol="AJP/1.3"
           address="::1"
           port="8009"
           redirectPort="8443" />

 

ㅇ변경후

<Connector protocol="AJP/1.3"
           address="::1"
           port="8009"
           redirectPort="8443"
           secretRequired="false"/>
