问题
My web application makes use of a web framework by including the jar (which has compiled JSPs) into the lib. I'm working on migrating from Tomcat 7 to Tomcat 9. On running the application, I get the below error -
java.lang.NoSuchMethodError: org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(Ljava/lang/String;Ljava/lang/Class;Ljavax/servlet/jsp/PageContext;Lorg/apache/jasper/runtime/ProtectedFunctionMapper;Z)Ljava/lang/Object;
Unfortunately, I don't have the code for the web framework. The same set up works on Tomcat 7. Is there any way, I can get rid of this error?
