I'm using Apache POI for extracting data from Excel into java.
If there any error happens while the page is loading, then we have to restart the tomcat service.
For example, I am extracting the data from Excel, if excel has no issues, then the incoming data is correct. If there is any error I get a null pointer exception, and after that, even if we try to run jsp, the jsp file does not run, and we have to the restart the service.
