Unhandled Exception in JSP

Last modified: 03 December 2024

Reports exceptions that are thrown by top-level JSP scriptlets.

Example:

<%!
String getFormattedDate() {
  ...
  throw new IllegalArgumentException(...); // Error
}
%>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>Hello, JSP!</title>
</head>
<body>
<i>Today is <%= getFormattedDate() %></i>
</body>
</html>

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | JSP

NOTE: Such JSP pages will compile, because the servlet container wraps all JSP code in a try {} catch() {} block, but they will produce runtime exceptions when deployed on the server.
