Final answer:
To include a Java class in a Servlet, use the 'import' statement with the package and class name at the start of the Servlet file. Make sure the class is in the classpath of the servlet container.
Step-by-step explanation:
How to Include a Java Class into a Servlet
To include a Java class in a Servlet, you need to import the class within the Servlet code. This is done at the beginning of the Servlet file using the import statement. For example, if you have a Java class named MyClass in a package named com.example.utilities, you would include it in your Servlet with the following import statement:
import com.example.utilities.MyClass;
Once imported, you can create and use instances of MyClass within your Servlet methods just as you would in any other Java class. It's essential to ensure that the class you are importing is in the classpath, which means that the servlet container can find and load the class. This typically involves placing the class files or JAR containing the class in the WEB-INF/classes or WEB-INF/lib directories of your web application.
If your Java class is in the default package (has no package statement), then you won't need an import statement. However, it's best practice to use packages to organize your code and avoid class name conflicts.
