我正在尝试将 Web 应用程序从 Webspiere 迁移到 Tomcat 7。我正在使用 Spring Tool Suit (sts)。尝试运行应用程序时出现以下异常。该项目未作为 Maven 项目维护。我尝试了从类路径中具有 jsp jar 和 servlet jar 的两种选项，但没有它们。问题还是一样的。

org.apache.jasper.compiler.TldLocationsCache tldScanJar
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

org.apache.catalina.core.StandardContext loadOnStartup
SEVERE: Servlet /myapp threw load() exception
org.apache.jasper.JasperException: /admin_login.jsp (line: 3, column: 0) Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV

似乎您在类路径中缺少 JSTL 标记库，或者您可能在类路径中缺少了 standard.jar。

检查这个 和这个。
