最近新項目打算用struts2與weblogic服務器搭建項目環境，本以為會很容易成功，沒想到卻花了我好多時間。
進入正題：
環境：weblogic9.2 MP3 、JDK1.7.3、MyEclipse8.5
一開始按照基本的struts2搭配環節進行，發現在服務器啟動的時候，報錯,大致如下：
<<WLS Kernel>> <> <> <1272511848921> <BEA-101165> <Could not load user defined filter in web.xml: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter.

在網上查了好多資料，都以為是jar包沖突，或者是jar沒有導入導致的，其實還有另外的一種原因。
weblogic9.2啟動部署的時候，默認的自帶的jdk1.5，而這個時候我們的MyEclipse8.5用的是自己安裝的jdk1.7.3，導致版本不一致
解決方法如下：右鍵需要部署的項目，選擇—》properties—》java Compiler
將項目的編譯器改成jdk.1.5的版本就OK了，再次部署，就不會出現找不到action的錯誤了
