tomcat下配置struts2的Unable to load configuration. - bean - jar:file問題
今天在用tomcat配置struts2的時候發(fā)現(xiàn)一個之前在resin下沒有發(fā)現(xiàn)的問題。
先說說環(huán)境。
我的環(huán)境是myeclipse6.5+tomcat6.0.26+struts2.1.8。
創(chuàng)建了一個web project后將
commons-logging-1.0.4.jar
freemarker-2.3.15.jar
ongl-2.7.3.jar
struts2-core-2.1.8.1.jar
xwork-2.1.6.jar
這幾個jar包拷貝到工程下的/WEB-INF/lib/文件夾后然后配置好web.xml和struts.xml后啟動tomcat報出了

這樣的錯誤。這個是在resin下運行時候沒有遇到的。不知道和webserver的版本是不是有些關系。
之后查了查原來是少了一個commons-fileupload-1.2.1.jar。于是從struts的lib中把這個jar包拷貝到工程的lib下再重啟tomcat問題解決了。
