Some time ago, I saw several beta versions of tomcat7.0 released. I didn't test it because it was not stable. Today I saw the news that the official version of tomcat7.0 has been released. I downloaded it on the official website to see how it works. <Xmlnamespace prefix = "O"/>

The following describes some new features of Tomcat 7:

◆ Tomcat 7 fully supports servlet 3.0 specifications

◆ Tomcat 7 added support for Java annotations

◆ Tomcat 7 dynamically configures the function of referencing class libraries through web. xml

◆ Tomcat 7 Improves secure session tracking

◆ Tomcat 7 improves the functions of the relational service so that the address can be configured when it is disabled

◆ Tomcat 7 has improved the startup class. Currently, no configuration files are required during Tomcat 7 startup.

◆ Configuration parameters are added for Tomcat 7, which can be used to configure the execution queue timeout time for Tomcat 7 and the execution limit is large or small.

... ...

New features facilitate and better support for new Java features. I feel that Tomcat 7's support for servlet3.0 and Java annotaion should be based on the need to popular 0 configurations or minimize configuration files. The arrival of servlet3.0, the most profound difference is that a servlet can be configured directly at the code level and does not need to be configured on the web. configured in XML.

Download tomcat7.0 and integrate it with myeclipse. Configure tomcat7.0 for myeclipse, as shown in figure
