Could not find or load mail clas in maven jar

The classic "Could not find or load mail class" error!

This error typically occurs when your Java application is trying to use a mail-related class (e.g., javax.mail.*) but the necessary mail library is not properly configured or included in your project.

Here are some common solutions to resolve this issue:

  1. Check your Maven dependencies: Make sure you have the correct mail library dependency in your pom.xml file. You can add the following dependency:
    <dependency>
 <groupId>org.glassfish.jersey.containers</groupId>
 <artifactId>jersey-container-jaxrs-server</artifactId>
 <version>2.30</version>
</dependency>

    or

    <dependency>
 <groupId>com.sun.mail</groupId>
 <artifactId>javax.mail</artifactId>
 <version>1.6.2</version>
</dependency>
  2. Verify the mail library is included in your classpath: Check if the mail library JAR file is included in your project's classpath. You can do this by:
    • Right-clicking on your project in Eclipse and selecting "Properties" > "Java Build Path" > "Libraries" > "Add External JARs" and selecting the mail library JAR file.
    • In IntelliJ IDEA, go to "File" > "Project Structure" > "Modules" > "Dependencies" and add the mail library JAR file.
  3. Check for conflicts with other libraries: If you have other libraries that also provide mail functionality, it might cause conflicts. Try removing or updating these libraries to see if it resolves the issue.
  4. Clean and rebuild your project: Sometimes, a simple clean and rebuild of your project can resolve the issue. Run the following Maven command:
    mvn clean package
  5. Check your Java version: Make sure you're using a compatible Java version. The mail library might not be compatible with your Java version. You can check your Java version by running java -version in your terminal.
  6. Check for any typos or incorrect imports: Double-check your code for any typos or incorrect imports related to the mail library.

If none of these solutions work, please provide more details about your project, including your pom.xml file, Java version, and any relevant code snippets.
