JAVA常見錯誤收集

1.javax.naming.NameNotFoundException: Name java:comp is not bound in this Context

=====>

--這是在初始化context時(Context envCtx = (Context) ctx.lookup("java:comp/env");)拋出的異常；解決方案是把工程/WEB-INF/lib下面naming-common.jar,naming-factory.jar,naming-resources.jar三個jar包刪除；

2. unable to complie class for jsp

===>
是因為TOOL.JAR   SERVLET_API.JAR與TOMCAT 有衝突。

3.org.Apache.struts.taglib.html.MessagesTei

關鍵字: struts
tomcat5.5 中 JasperException: Failed to load or instantiate TagExtraInfo class:org.Apache.struts.taglib.html.MessagesTei

tomcat5.5 中 JasperException: Failed to load or instantiate TagExtraInfo class:org.Apache.struts.taglib.html.MessagesTei

JasperException: Failed to load or instantiate TagExtraInfo class: com.acme.tag.IterateTEI

等等...

==>

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。
