Question

I’m working on a JSP page, but I’m running into a null pointer at run time. In an attempt to isolate the problem, I hard-coded the expected variable response instead of using a getter (it was previously action.getName(psi.getLong()) )). Sure enough, I got an error when I tried to run the page with the raw long.

An error occurred at line: 70 in the jsp file: /auth/foo/viewBar.jsp
The literal 9000000000 of type int is out of range 

70:             <%long sarah = 9000000000; %>
71:             <td> <%= StringEscapeUtils.escapeHtml(""+action.getName(sarah)) %></td>

getName is defined elsewhere as follows

public String getName(long mid) throws DBException {
        try {
            return personnelDAO.getName(mid);
        } catch (fooException e) {
            e.printStackTrace();
            return "exception retrieving name";
        }

But judging by the above, I’d guess that the 9000000000 isn’t even getting passed that far. Can .JSP not handle longs?

Furthermore, could this error have caused the nullpointer error I was experiencing at runtime, or is that a wholly separate error? (That’s all the stacktrack says: NullPointerException: null)

Edit: D’oh. Using a factory, forgot to instantiate one of the DAOs I’m using. That’d be the cause of the NullPointer then. Case closed.

Answer 1

Try to use

9000000000L.

You need to specify the type in this case.
Or use

new Long("9000000000")
