How to fix 'javax.servlet.ServletException: Servlet.init()' Error for Tomcat

Question

The Problem is that the Error only seems to appear when I deploy it at my Linux Server (Tomcat 9.0.22). On Windows there is no Problem at all (Tomcat 9.0.27). The Server itself seems to work, just when I try to call the REST API of the Application there appears this weird error (refear the Stacktrace).

The Maven dependencies:

    <properties>
        <jersey.version>2.16</jersey.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Ok. Look at this question, maybe it is the same issue https://stackoverflow.com/questions/45187624/java-lang-nosuchmethoderror-javax-ws-rs-core-application-getpropertiesljava-u — Juliano Pacheco, Oct 30 '19 at 17:04

Ok,

Issue is solved, run the mvn dependency:tree -DVerbose Command and found the bad boy. In my case it was javax.ws.rs:jsr311-api from the dependency io.swagger:swagger-jaxrs

I solved the issue by including the following exclusion:

        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-jaxrs</artifactId>
            <version>1.5.0</version>

            <exclusions>
                <exclusion>
                    <groupId>javax.ws.rs</groupId>
                    <artifactId>jsr311-api</artifactId>
                </exclusion>
            </exclusions>

        </dependency>

Thanks for your help!

Servlet.init() exceptions are often related to dependency versioning.

You should not use version LATEST on your dependencies. Jackson Core, more specifically. Probably your application is using a different, non-compatible, version of Jackson Core in the Linux server.

This answer explains why using version LATEST is a problem. You should always use specific versions to avoid compatibility problems.

I replaced all LATEST entries and also found an old dependency. Now it works just finde, thank you! – Sollder1 Oct 30 '19 at 18:34
