Tomcat이 디폴트로 약 2메가 정도의 Post 데이터만 처리…

따라서 $TOMCAT_HOME/conf/server.xml 에서 Connector> 엘리먼트에 maxPostSize를 추가..
(0이면 무제한인듯)

<Connector port="8102" minProcessors="1" maxProcessors="5"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           debug="0" connectionTimeout="120000" useBodyEncodingForURI="true"
           maxPostSize="3145728"
           protocol="AJP/1.3" />
