I am trying to upgrade the struts version from 6.2 to 6.3.0.2.

Struts :

struts2-core-6.3.0.2.jar

struts2-spring-plugin-6.3.0.2.jar

struts2-tiles-plugin-6.3.0.2.jar

Spring version:5.3.34

Getting below error after upgrading to 6.3.0.2

ERROR org.springframework.web.servlet.DispatcherServlet

org.springframework.beans.factory.BeanCreationException: Error creating bean with name tiles Configurer’s Lookup method resolution failed; nested exception is java.lang.IllegalStateException: failed to introspect Class [org.springframework.web.servlet.view.tiles3.TilesConfigurer) from ClassLoader (webappClassLoader)

.

Caused by: java.lang.NoClassDefFoundError: org/apache/tiles/startup/TilesInitializ
er

removed below tiles jars for this upgrade.

tiles-compat-3.0.0.jar
tiles-core-3.0.8.jar
tiles-el-3.0.8.jar
tiles-Freemarker-3.0.8.jar
tiles-jsp-3.0.8.jar
tiles-ognl-3.0.8.jar
tiles-request-api-1.0.7.jar
tiles-request-sp-1.0.7.jar
tiles-request-servlet-1.0.7.jar
tiles-servlet-3.0.8.jar
tiles-template-3.0.8.jar

Getting below errors after removing tiles jars.

Java. Lang. IncompatibleClasschangeError: Class org.apache.tiles.el.fiattributeEvaluator does not implement the requested Interface org.apache.tiles.evaluator Attributevaluater at org.apache.tiles.impl. BasicTilesContainer evaluate (BasicTilesContainer.java:267)

Kindly provide some hint to resolve this errors.

Spring 5.3.34 is compatible with struts 6.3.0.2?
Can we remove the external tiles?
