Entity Bean Software Recommendations

I am developing Which software components must be installed on Tomcat 10 in order to implement Jakarta EE 10? As of my last update in September 2021, the following software components are required to fully implement Jakarta EE 10 on Apache Tomcat 10. Note that Tomcat is primarily a servlet container and does not offer a full Jakarta EE platform by default. However, it is possible to extend its capabilities through additional libraries and configurations. 1. **Apache Tomcat 10**: The primary component for running web applications. Make sure to download and install the latest stable version from the official website. Tomcat 10 specifically targets the use of Jakarta Servlet 5.0, part of Jakarta EE 9 and above, which offers fundamental building blocks for Jakarta EE applications. 2. **JDBC Drivers**: If your Jakarta EE application interfaces with a relational database, ensure that the appropriate JDBC drivers for your database are placed in the `lib` folder of your Tomcat installation. 3. **JNDI Resources**: Configure JNDI resources such as database connections in the `context.xml` or `server.xml` files within the `conf` directory of your Tomcat installation. 4. **Jakarta EE 10 Libraries**: You may need to add specific libraries to support other Jakarta EE 10 APIs like Jakarta Mail, Jakarta Transactions, and Jakarta Messaging, among others. These can be added to the `lib` folder or packaged with your application. 5. **CDI Implementation (e.g., Weld)**: To support Contexts and Dependency Injection (CDI), you'll need to include an implementation like Weld. The Weld jars should be placed in the `lib` folder and configured properly. 6. **Jakarta Bean Validation**: To add Bean Validation capabilities, you would need the specific jars like `hibernate-validator` and its dependencies in the `lib` folder. 7. **JSTL (Jakarta Standard Tag Library)**: To utilize JSP tags, include JSTL libraries either in your application’s `WEB-INF/lib` directory or in Tomcat’s global `lib` directory. 8. **JavaMail API**: If your application requires email capabilities, you'll need to include the Jakarta Mail library in the `lib` folder. 9. **Security Providers**: If your application requires specific authentication or authorization mechanisms, you might need to include additional libraries or configure the built-in options provided by Tomcat, such as JAAS, in the `server.xml` or `web.xml` file. 10. **Logging Framework**: Tomcat uses JULI for logging, but you may need to include other logging frameworks like Log4j if your application requires it. 11. **Web Application Archive (WAR)**: Finally, your Jakarta EE 10 application should be packaged as a WAR file and deployed to Tomcat's `webapps` directory. 12. **Build Tools**: While not strictly part of the Tomcat installation, using a build tool like Maven or Gradle can streamline the process of managing dependencies and building your Jakarta EE 10 application. Once all these components are in place and properly configured, your Apache Tomcat 10 installation should be capable of running a Jakarta EE 10 compliant application. Note: Always refer to the most current documentation and guidelines as the Jakarta EE specifications and Apache Tomcat may have been updated after my last training data in September 2021.
The following software is recommended to gain the benefits of Entity Beans.
  1. For Solaris: Java SE 6 or later Solaris Reference Implementation
    Java SE 6
  2. For Windows operating systems:
    Java SE 6 or later for Windows Production Release
  3. Java SDK, Enterprise Edition software (latest edition)
    Java EE at a Glance

Currently, to download the Java 2 SDK, Enterprise Edition software, you must be a member of the Oracle Technology for Java Developers. If you are not a member, you can register at the above URL and then download the software. Later in the course we will explain how to install the software.

Please note that the Java 2 SDK, Enterprise Edition requires the Java 2 SDK v1.2.2 or later. Earlier versions will not work with the current version of the Enterprise Edition.

If you have been developing Java code for some time, you are probably familiar with some of the more popular IDE's such as
  1. Eclipse
If your IDE is not Java 2 SDK v1.2.2 or later compliant, then create your code with the IDE and simply compile it with the Java 2 javac[1] and run it with the Java interpreter.
