+# Quick Guide for Tomcat
+
+* [Download](https://tomcat.apache.org/download-80.cgi) and install the Tomcat server
+
+* Tomcat management [page](http://localhost:8080/manager) 
+
+  * ![](./tomcat-manager.PNG)
+
+* Build the java spring boot project `gradle build`. Artifacts in `build\libs\something.war`
+
+* Copy java `something.WAR` file to `C:\Program Files\Apache Software Foundation\Tomcat 8.5\webapps\ROOT.war`
+
+* run the server on CLI
+
+  ```sh
+  // "jpda" to allow remote attach to debug java code @ port 8000
+  ///
+  C:\Program Files\Apache Software Foundation\Tomcat 8.5\bin> .\catalina.bat jpda start
+  ```
+
+* Tomcat will extract WAR file to `C:\Program Files\Apache Software Foundation\Tomcat 8.5\ROOT`
+
+* Build vueJS FE `npm run-script build`. Build artifacts will be created under `dist`
+
+* Copy vueJS build artifacts contents `dist` to `C:\Program Files\Apache Software Foundation\Tomcat 8.5\ROOT\WEB-INF\classes\public`
+
+* Reload tomcat to refresh the FE component
+  
+  * ![](./FE.PNG)
+  
+* Now you can access the web from browser
+  
+  * FE page : `http://localhost:8080`
+  * BE api : `http://localhost:8080/v1/merchant/...`
