Thanks to all who replied to me in private and on the list. Looks like JRun's
parser has a problem.
When you space out expressions like this in JSP page:
<%= r.getElement(4) %> <%= r.getElement(0) %>
the JSP engine (JRun) produces the following code:
...
out.print("\r\n\r\n<td bgcolor=FF9999><font face=Arial size=-1> ");
out.print(r.getElement(4) );
out.print(r.getElement(0) );
out.print("</font></td>\r\n");
...
Which means that the space between the two expressions is omitted and the
output is this:
element4element0
This is annoying because if you want to do more than one of these expressions
like that in a row separated by space and you use then if anyone is
empty you will get a bigger space on your page:
element4 element3 element0
The solution is to do the following:
<%= r.getElement(4) +" "+ r.getElement(3) +" "+r.getElement(0) %>
I use JRun 2.3.1 build 149 with JSP 1.0
Could JRun people verify/fix this?
Thanks to all,
dave.
