無法為JSP編譯類：無法解析類型java.util.Map $ Entry從所需的.class文件間接引用它
你必須使用支持JDK 8的最新版本的tomcat。
我可以確認apache-tomcat-7.0.35不支持JDK8，也可以確認apache-tomcat-7.0.50不支持JDK8。
解決方法我無法獲取tomcat7來編譯jsps。直到運行示例servlet一切正常，并且服務已啟動并正在運行。我正在運行oracle java 8。
誰能指出我正確的方向？
這是堆棧跟蹤：

該代碼看起來像這樣，這是來自tomcat7的示例代碼，所以我想這是正確的。
<%@ taglib prefix="mytag" uri="/WEB-INF/jsp2/jsp2-example-taglib.tld" %><html><head> <title>JSP 2.0 Examples - Hello World SimpleTag Handler</title></head><body><h1>JSP 2.0 Examples - Hello World SimpleTag Handler</h1><hr><p>This tag handler simply echos "Hello,World!"
