我无法获取tomcat7来编译jsps。直到运行示例servlet一切正常，并且服务已启动并正在运行。我正在运行oracle java 8。谁能指出我正确的方向？这是堆栈跟踪：type Exception reportmessage Unable to compile class for JSP:description The server encountered an internal error that prevented it from fulfilling this request.exceptionorg.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 1 in the generated java fileThe type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class filesStacktrace: org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:102) org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:331) org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:468) org.apache.jasper.compiler.Compiler.compile(Compiler.java:378) org.apache.jasper.compiler.Compiler.compile(Compiler.java:353) org.apache.jasper.compiler.Compiler.compile(Compiler.java:340) org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:646) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:357) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728)note The full stack trace of the root cause is available in the Apache Tomcat/7.0.35 logs.该代码看起来像这样，它是tomcat7的示例代码，所以我想这是正确的。<%@ 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!" It's an example ofa very basic SimpleTag handler with no body.</p><br><b><u>Result:</u></b><mytag:helloWorld/></body></html>
