Openjpa Open Source

I started to get started with Linux in my freshman year and learned about free software and open-source sports. Now I think back, at that time, open-source sports were not so popular! At least in China, there is no such thing in the eyes of one of my students. however, now it is different that the open-source community is based on the Linux kernel and GNU tool, which is increasingly powerful and covers more and more widely. from basic operating systems to development tools, and from development tools to commercial applications, the momentum is fierce, so many large companies in the industry do not dare to despise.

The development of Linux has a slight impact on the desktop market of windows. Although it is a little impact, it can give this giant a little impact, and the industry is enough to prove its momentum. now, Novell, RedHat, and Ubuntu are competing with Microsoft for a single man-machine desktop system. in the server market, open-source Linux is even more advantageous. Linux and other UNIX-like systems occupy half of the server market with their openness and good stability.
The first integrated open-source development environment, Eclipse. eclipse has won the favor of developers with its excellent scalability. since eclipse became popular, other development tools have become cool and cool. It is a "Eclipse! Even Borland's JBuilder could not escape the surging tide and eventually disappeared from the trend.

At the same time with Eclipse, there is also JBoss. With its advanced design concept and excellent pluggable capabilities, this J2EE server is in conflict with other large manufacturers' middleware servers in the J2EE Middleware market, the open-source Java community is faced with challenges.

Later, spring, hibernate, and JUnit are worthy of the Java open-source community. Although their respective directions are different, the following highlights represent the latest ideas of the entire Java Development camp, spring advocates simplicity and beauty. Hibernate is devoted to solving the O/R ing problem. The unit test carried by JUnit brings new vigor to the entire Java camp.

The official strong momentum may make many developers realize that the power of open source is better to take the initiative to integrate with the tide rather than continue to close their own customs. in this tide, we found a new business model and made profits in a new way. as a result, we can see that various hardware vendors constantly support the Linux operating system, IBM has ported Lotus Notes to Linux, and we can see the schedule for sun to open Java, we can see that Bea opened openjpa today and tomorrow ......
