This is a green running environment with integrated jre,tomcat,mysql, which can be run directly after decompression. No need for users to install Jre,tomcat,mysql, a key in place, looks like a desktop Web application. In other words, it's like a combination of web and desktop applications.The entire project was compressed to 34M (with two simple Web applications), I think the current bandwidth and hard disk

1. Tomcat Mode: Configure the connection pool in Context.xml, then write the configuration code in Web. XML (You can also configure the connection pool in the Server.xml file), the difference between the two methods is that the context element has been isolated from the Server.xml file in the Tomcat6 version and above , put it in a context.xml file. Since Server.xml is a resource that cannot be reloaded dynamically, once the server has been started, t

If you rely on scripting to build a Tomcat container instance, a command can be done, why not. Fortunately, Docker provides dockerfile as a script to build Docker images, avoiding the i

The way I do it now:1. When configuring Tomcat in Eclipse, choose Create context file instead of Server.xml, the benefit is that the file can be arbitrarily named, consistent with the virtual directory (that is, the attribute path in XML). When Tomcat loads a project, it scans all the XML files in the Conf\catalina\localhost directory and then loads them according to the configuration.The XML file in the Co

thread or a small number of threads to handle a large number of requests. For performance, the server concurrency of NIO is generally greater than that of bio, so high-performance servers can be implemented. If interested, you can learn some of the NIO-based network programming frameworks, such as Netty, MINA.Finally, answer the question that the Lord speaks of Tomcat. Tomcat runs can choose either bio or
