java - org.apache.jasper.JasperException : Unable to compile class for JSP and java. io.FileNotFoundException : programs_jsp. java(权限被拒绝)

Question

我正在将带有 JSP 页面的应用程序从 Weblogic 服务器移动到 Tomcat，但在执行此操作时遇到以下错误。我创建了一个部署在 tomcat 上的 war 文件，并将其放在 tomcat 的 webapps 文件夹中，然后运行 ​​bin/startup.sh 脚本将 war 文件部署到 tomcat 服务器上。但是，当我查看 tomcat 目录下的工作文件夹时，它是空的并且没有文件 /opt/mw/tomcat/ssloyalty-qa/ssloyalty-gui/work/Catalina/localhost/traveler/org/apache/jsp/pages/programs_jsp.java (Permission denied) 中提到的错误。我的应用程序中有几个 JSP 页面可以正确显示，没有任何错误。只有少数人抛出了下面给出的这个错误。

确保启动tomcat服务器的用户对以下文件夹有写入权限。

/opt/mw/tomcat/ssloyalty-qa/ssloyalty-gui/work/Catalina/localhost/
