Tomcat Server下發布網頁錯誤及解決方法
1﹑tomcat5.5 中 JasperException: Failed to load or instantiate TagExtraInfo class:org.Apache.struts.taglib.html.MessagesTei
JasperException: FailedtoloadorinstantiateTagExtraInfo class: com.acme.tag.IterateTEI(
注意這里有可能是別的相近的提示。)
?
原因是 web-inf/lib/下出現了jsp-api.jar和,serverlet-api.jar，把它們刪除，然後重新啟動 web應用即可。

這個錯誤﹐從網上搜索時﹐一般說是JDK版本問題﹐但我更新JDK(由1.5.0~1.5.0.06)還是報以上錯誤﹐后來我又更新了一下TOMCAT(由tomcat5.0.28更為5.5.9)問題解決。
在測試AJAX時也遇到過要更新TOMCAT的問題﹐所以個人覺得如果JDK用1.5﹐TOMCAT也應用5.5.X以上版本最為保險。
