I am getting the following errors for lines 31 ,32 ,33
The method write(String, int, int) in the type Writer is not applicable for the arguments (String, String)
Syntax error on token "editable", , expected
What should I do to solve this?
Try this:
while (rs.next())
{
out.write("<tr id='" + rs.getString("PresidentID") + "'>");
/*line 31*/ out.write("<td class=\"editable\" title='FirstName'>" + rs.getString("FirstName") + "</td>");
/*line 32*/ out.write("<td class=\"editable\" title='LastName'>" + rs.getString("LastName") + "</td>");
/*line 33*/ out.write("<td class=\"editable\" title='Bio'>" + rs.getString("Bio") + "</td>");
out.write("</tr>");
}
You are not escaping " in class name of tag. Also consider my comment never write business logic in jsp. Do database connectivity in servlet. Jsp should be only used for presentation.
Escape your quotation marks (or use single quotes).
Change this:
out.write("<td class="editable" title='FirstName'>" + rs.getString("FirstName") + "</td>");
to this:
out.write("<td class=\"editable\" title='FirstName'>" + rs.getString("FirstName") + "</td>");
or this:
out.write("<td class='editable' title='FirstName'>" + rs.getString("FirstName") + "</td>");
Looks like a typo:
out.write("<td class="editable" ...
should be
out.write("<td class='editable' ...
instead.
