JSF 1.x generic exception handling

Question

If I have an exception in my business layer (e.g. a SQL exception in my JDBC connection bean), how can I propagate it with a custom message to a global error.jsp pa

Answer 1

The general way to display error message to the user in JSF is to use FacesMessage:

On Java side:

...
if (errorOccurred) {
    FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("An error occurred blabla..."));
}

and in the JSF (JSP or XHTML) page, simply use the component in your page in order to display the error.
