I have a simple application which should load some simple JSP pages as per the URLs provided
- http://localhost:9191/mypath/ --> Should load page1.jsp
- http://localhost:9191/mypath/first.do --> Should load page1.jsp
- http://localhost:9191/mypath/second.do --> Should load page2.jsp
On using the application from within IntelliJ the above URLs work as expected.
However, on starting the application with - java -jar app.jar --spring.config.location=file:./application.properties it returns 404 for all the above mentioned URL's.
Unable to figure out why and would appreciate if someone can point me to anything I might be missing.
Details of my project as below. Haven't provided the details of the JSP as they are simple pages with one line of text.
Java version : 11.9
Spring Boot version : 2.3.4.RELEASE
