Ten Technologies Every Java Developer Should Know
“Time and tide wait for no man” declares an ancient proverb. If you currently are working in the software industry, you know this truth still applies. To effectively work on Java projects, an understanding of basic Java and Java EE APIs, such as JDBC and servlets, is required because they serve as the foundation of the application.
If you want to be a participant in application development, however, you need more knowledge. So what other technologies/APIs are critical to being a project member? Based on field experiences and in the classroom of java-development’s consultants and instructors, we have compiled the top 10 technologies/APIs every Java developer should know:
1. At least one MVC Framework like JSF, Struts, or Spring MVC
2. Hibernate or JPA
3. Dependency Injection (as demonstrated in Spring or Java EE through @Resource)
4. SOAP based Web Services (JAX-WS)
5. Some build tool (Ant, Maven, etc.)
6. JUnit (or other Unit Testing framework)
7. Version control
8. JSTL
9. Application server/container configuration management and application deployment (whether it is WebSphere, Tomcat, JBoss, etc. you need to know where your application runs and how to improve its execution).
10. AJAX
Other technologies/APIs that didn’t make the top ten, but could certainly be successfully argued for inclusion in a developer’s repertoire are: design patterns, debugging tools/techniques, and continuous integration.
If you are starting off the new year and looking at professional goals to set for yourself or your development team, take a look at this list and see if it can help. If you need some help with these topics, take a look at java-development’s Java and .NET Training. Give us a chance to help improve your standing in the development community.
If you have been doing Java for some time and have a few gray hairs named after your favorite (or infamous) projects, what APIs and/technologies do you think need to be on the list? Feel free to comment and leave us your thoughts on what needs to be added or removed from the list.
