Thank you for your reply Finally, I found that conflicts occurred between taglib tags and "org" variables This is the simplest jsp example: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <% String org = (String)session.getAttribute("org_id"); %> <body> <c:if test="true"> <%=System.currentTimeMillis()%> </c:if> </body> </html> I understand that this is a conflict But I don't understand why the old version of Tomcat has no problem. Theoretically Tomcat's minor upgrades(7.0.75==>7.0.76) should not change compatibility Our legacy project takes the "org" variable as the basic parameter of the JSP. Hundreds of pages use the variable Recently I want to upgrade the Tomcat server to the new version Maybe I can only give up -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
