Java.lang.TypeNotPresentException: Type javax.servlet.http.HttpServletRequest not present - Troubleshooting Guide

This exception occurs when the class 'javax.servlet.http.HttpServletRequest' is not found.

The error stack trace suggests that this class is required by a component in your application, but it is not present in the classpath. This can happen if the required dependency is not included in your project's dependencies or if it is not being loaded correctly.

To resolve this issue, you can try the following steps:

1. Make sure that the required dependency for Servlet API is included in your project's dependencies. If you are using Maven or Gradle, check the dependency configuration in your build file. For Maven, you can add the following dependency to your pom.xml:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.1</version>
    <scope>provided</scope>
</dependency>

2. If you are using an IDE, check if the Servlet API jar file is included in the project's classpath. If not, you can add it manually by right-clicking on the project, selecting 'Build Path' or 'Properties,' and then adding the Servlet API jar file to the classpath.

3. If you are deploying your application to a container or server, make sure that the Servlet API jar file is available in the server's classpath.

By ensuring that the Servlet API dependency is correctly included and available in the classpath, the 'javax.servlet.http.HttpServletRequest' class should be found and the TypeNotPresentException should be resolved.
