2.6頁面調用后無法登陸
在學習完2.6節（頁面調用）之后，發現可以加載登陸頁面，但輸入正確的用戶名和密碼后，卻無法登陸進去。myeclipse自動跳到 debug頁面，出錯信息為：org.apache.jasper.compiler.TldLocationsCache?tldScanJar 信息:?At?least?one?JAR?was?scanned?for?TLDs?yet?contained?no?TLDs.?Enable?debug?logging?for?this?logger?for?a?complete?list?of?JARs?that?were?scanned?but?no?TLDs?were?found?in?them.?Skipping?unneeded?JARs?during?scanning?can?improve?startup?time?and?JSP?compilation?time.
