I tried to create/run a basic JSP and ran into the following error. I saw that other people have had similar problems, however, I haven't been able to find (or properly implement) a solution to the problem at hand yet. Any help would be appreciated!

I faced similar issue and it was caused because I had written WebServlet Path in the .java file as well as in the web.xml . Removing it from any one location works fine for me.

In the .java file

@WebServlet("/index1.jsp")

and in web.xml

<servlet>
    <servlet-name>Logout</servlet-name>
    <servlet-class>tpc.Logout</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Logout</servlet-name>
    <url-pattern>/index1.jsp</url-pattern>
</servlet-mapping>

You must have packaged the servlet-api.jar along with the other libraries in your war file. You can verify this by opening up your war file and navigating to the WEB-INF/lib folder.

Ideally, you should not provide the servlet-api jar. The container, in your case Tomcat, is responsible for providing it at deploy time to your application. If you try to provide it as well, then issues arise due to version mismatch etc. Best practise is to just avoid packaging it. Remove it from the WEB-INF/lib.

Additional Information

If you are using maven for your packaging, then simply add the provided tag with the dependency and maven will make sure not to package it in the final war file. Something like

<dependency>
    <artifact>..
    <group> ...
    <version> ...
    <scope>provided</scope>
</<dependency>

Your webapp has servletcontainer specific libraries like servlet-api.jar file in its /WEB-INF/lib. This is not right.

Remove them all.

The /WEB-INF/lib should contain only the libraries specific to the webapp, not to the servletcontainer. The servletcontainer (like Tomcat) is the one who should already provide the servletcontainer specific libraries.

If you supply libraries from an arbitrary servletcontainer of a different make/version, you'll run into this kind of problems because your webapp wouldn't be able to run on a servletcontainer of a different make/version than where those libraries are originated from.

How to solve: In Eclipse Right click on the project in eclipse Properties -> Java Build Path -> Add library -> Server Runtime Library -> Apache Tomcat

Im Maven Project:-

add follwing line in pom.xml file

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>${default.javax.servlet.version}</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>${default.javax.servlet.jsp.version}</version>
            <scope>provided</scope>
        </dependency>
