Simply put, these three methods encapsulate some common functional methods to normalize these methods, avoiding repeated and fragmented compilation of similar code in jsp development. In other words, struts2 is responsible for processing customer requests and forwarding them to specific action methods for execution. This process uses struts2's Loopers, filters, interceptors, and other functions. The struts2 tag function is equivalent to the jsp tag. The advantage of the struts2 tag is that it us

In the java Enterprise application field, the powerful functions of ejbs are the same as the complicated configurations of ejbs, and they are also known for their difficulties in learning. But before, what can we do? You can only learn ejbs with a hard head. It is a bit of "understanding that there are tigers in the mountains and moving towards tigers. There has been an optimistic change in the form. The popularity of java open source has made the development of java Enterprise applications no l
