将String变量从Java传递到JSP

Question

I am trying to pass a string variable from my java class as follow:

request.setAttribute("fdata",fileName); 

in order to send it to my jsp file as follow:

var fd ="0";
fd=<%= (String) request.getAttribute("fdata").toString()%>;
document.getElementById("reed").value = fd;

the problem is that the 'fileName' which is a string variable in java is converted to integer for example if I pass this string : "5-9" the result that i see in 'reed' textbox is (-4) or if i pass "8-7" the result will be (1) and if I pass something else eg "5-8dfs" it doenst show anything. I think my jsp file sees the string variable as integer variables and mathematical operators instead of String variable itself, any hint or suggestions ??

Thanks very much.

Your JavaScript string doesn't have quotes. I think you want to do this instead:

fd="<%= (String) request.getAttribute("fdata").toString()%>";
