…tion section 7.3.1 alert in tomcat versions later than 7.0.70. Basically, the tags are referencing the tld files via a relative path (../../tlds). The JSP 2.2 spec says the tld files cannot be under /WEB-INF/tags, but with the relative path, they have links like /WEB-INF/tags/structure/../../tlds. One could reasonably argue that tomcat isn't checking the path properly, but this is an easy fix.

As quick solution, you can just copy below two libraries from the lib folder of tomcat 7.0.64 and place it in your project root or if you are using maven then add these two as dependency in your pom.xml file: jasper.jar This will resolve your issue. |

These changes fix the "Invalid tld file' error happening in tomcat after version 7.0.70/8.0.36/8.5.3 (see https://bz.apache.org/bugzilla/show_bug.cgi?id=59654).
The error mentions "JSP 2.2 specification section 7.3.1" because this error arises from the tag library descriptor (tld) files being referenced via a relative path in the tag files. To elaborate: the tags are referencing the tld files via a relative path (../../tlds). The JSP 2.2 spec says the tld files cannot be under /WEB-INF/tags, but with the relative path, they have links like /WEB-INF/tags/structure/../../tlds/... One could reasonably argue that tomcat isn't checking the path properly, but this is an easy fix.
