Use Eclipse to remotely debug Web applications deployed in Tomcat

Today, my colleague told me how to remotely debug a Web application deployed in Tomcat using Eclipse:

1. Install the decompressed version of Tomcat, because it seems that there is no catalina. sh (. bat) file in the Tomcat Windows installation directory;
2. Modify the JPDA_ADDRESS port in catalina. sh (. bat). For example, by default, this configuration isJPDA_ADDRESS = "8000"Now, change it to the port we want to use. Here we will use 8000 by default;
3. Start Tomcat, enter the $ {CATALINA_HOME}/bin directory in command line mode, and enterCatalina. sh (bat) jpda start
4. Start Eclipse, select the class you want to Debug and set the breakpoint, and then select the Debug sub-menu in the Debug toolbar. In the pop-up Debug selection window, select remote debugging in the menu on the left, enter the machine name and port, such as localhost and 8000, and then Apply and start Debug;
5. Open the browser and enter the page for debugging. The Debug window of Eclipse is activated, and Debug is now available.
