In IntelliJ IDEA, you can run JSP files locally by following these steps:

  1. Make sure that Tomcat server has been installed and configured correctly. If Tomcat has not been installed yet, please download and install it first.
  2. Open IntelliJ IDEA, click on the “File” option in the top menu bar, select “New”, and then choose “Project”.
  3. In the new project wizard, choose “Maven” or “Gradle” as the project build tool, and follow the prompts to create a new project.
  4. After the project is created, open “Project Structure” by using the shortcut “Ctrl + Alt + Shift + S”.
  5. On the left panel, select “Modules”, and then click on the “+” button, and choose “Web”.
  6. On the right panel, choose “Web Resource Directory” and set it to the directory where your JSP files are located.
  7. In the left panel, select “Artifacts” and then click the “+” button, choose “Web Application: Exploded”.
  8. Choose “Output Layout” from the panel on the right, then click on the “+” button and select “Web Directory”.
  9. Choose the “webapps” directory of your Tomcat server in the pop-up dialog box.
  10. Click on “Apply” and then click on “OK” to close the window.
  11. In IntelliJ IDEA’s toolbar, choose “Edit Configurations” (shortcut is “Alt + Shift + F10”), click the “+” button, select “Tomcat Server”, then choose “Local”.
  12. In the right panel, select “Deployment,” then click the “+” button, choose “Artifact,” and select the previously created Web Application.
  13. Choose “Server” in the left panel, then click the “+” button, and select “Local”.
  14. Choose the installation path for your Tomcat server on the right panel.
  15. Click on “Apply”, and then click on “OK” to close the window.
  16. In the toolbar of IntelliJ IDEA, select your Tomcat server, and then click the green “Run” button.
  17. Open the browser and enter “http://localhost:8080/your project name/your JSP file name.jsp” to run the JSP file in the browser.

Please note that you can adjust the settings according to your specific situation in steps 6 and 11. Additionally, if you are using a different server such as Jetty or Glassfish, you can select the appropriate server in steps 11 and 14.
