// get the locale of the client and create an appropriate date format
Locale loc = pageContext.getRequest().getLocale();
DateFormat df = DateFormat.getDateInstance(DateFormat.MEDIUM, loc);
try
{
// and write out the formatted date to the page
pageContext.getOut().write(df.format(new Date()));
}
catch (java.io.IOException ioe)
{
throw new JspTagException(ioe.getMessage());

incompatible object argument for function call

修改一处即可。
throw new JspTagException(ioe.getMessage());
}
// and skip evaluating the body of the tag (as there shouldn't be one)
return SKIP_PAGE;//这应该是return SKIP_BODY;
}
}
throw new JspTagException(ioe.getMessage());
}
// and skip evaluating the body of the tag (as there shouldn't be one)
return SKIP_PAGE;//这应该是return SKIP_BODY;
}
}
