Tomcat 8 is not scanning apache tiles TLD file inside the jar

Question

I'm setting up the spring webmvc project using spring boot 2.0.0 version. If i run the application inside the embedded tomcat, it runs fine. I tried deploying it in external standalone tomcat-8 server, it is working fine over there too. But i if package the war and deploy it in the tomcat-8 server configured within eclipse, then it throws below exception.

The absolute uri: http://tiles.apache.org/tags-tiles cannot be resolved in either web.xml

I included the dependency in the pom file as below.

<dependency>
            <groupId>org.apache.tiles</groupId>
            <artifactId>tiles-jsp</artifactId>
            <version>3.0.4</version>
</dependency>

I ensured that the tiles-jsp jar is present inside the WEB-INF/lib folder. But still its failing as it is not able to scan the jar for TLD. I tried changing the catalina.properties to include tiles-jsp*.jar. But it is still failing.

Please help me to fix this error.

Answer 1

Does your IDE automatically import dependencies?

Try cleaning your maven dependencies. Maven clean.

Or try the more brutal command dependency:purge-local-repository.

By the way notice that there's a newer version of your dependency 3.0.8 of 2017. The one that you are trying to use, the 3.0.4, is of 2014.

For me, war file when deployed works perfect. Had an issue where, when I run it under tomcat from inside IDE(Eclipse/STS), it threw error. Maven clean really helped, no other change needed. MAven clean-->build--> restart eclipse/sts tomcat. it works like a charm. Answer by desoss prompted me to perform maven clean. Thanks @desoss.
