• Enterprise Features
  It offers a range of enterprise-level features such as EJB, JPA, JMS, and web services, making it suitable for building complex applications.
• Java EE Reference Implementation
  GlassFish is the reference implementation of Jakarta EE (formerly Java EE), ensuring adherence to standards and compatibility with other Java EE technologies.
• Modular Architecture
  Using OSGi modules, GlassFish allows for a high degree of customization and the ability to deploy only necessary components, enhancing performance.
• Admin Console
  It features an intuitive and user-friendly administrative console, simplifying the management of server instances and deployed applications.

Possible disadvantages of Glassfish

• Performance Overhead
  Compared to other application servers, GlassFish might encounter performance issues under heavy load due to its extensive feature set.
• Complex Configuration
  Configuring GlassFish can be complex and time-consuming, especially for beginners, due to its numerous configurable options.
• Lower Adoption Rate
  It has a smaller user base compared to other application servers like Apache Tomcat or WildFly, potentially leading to less community support.
• Limited Commercial Support
  While there is commercial support available, it is limited compared to other leading application servers, which might deter enterprise users seeking robust support options.
• Resource Intensive
  GlassFish can be resource-intensive, requiring significant memory and processing power, which may not be ideal for smaller deployments.

Possible disadvantages of Eclipse Jetty

• Learning Curve
  Because of its numerous features and configuration options, Jetty may have a steeper learning curve for newcomers compared to simpler server options.
• Community Support
  While Jetty has a passionate user base, its community support may not be as extensive as more widely adopted solutions like Apache Tomcat.
• Default Configuration
  Jetty’s default settings may not always be optimal for all use cases, requiring developers to spend additional time tweaking configurations for specific needs.
• Limited Commercial Support
  Jetty has fewer commercial support options available compared to some other enterprise-level servers, which may be a concern for larger organizations.
• Complexity for Small Projects
  For small or less complex projects, Jetty's feature set and capabilities may be overkill, leading to unnecessary complexity and overhead.
