Hi,
I want to append a new line character('\n') at the end of a string and then display it so that they come one below the other.
I tried something like this -
<c:set var="tempStr" scope="page" value="${someStr}\n" />
This is not working. Can somebody tell me the correct way of going about it.
Thanks in advance,
Sam.

You could try:
<c:set var="tempStr" scope="page" value="${someStr + '\n'}" />
EL will concatenate the String with the \n character.

I Hope This Helps

Also, I hope you realize, HTML rendering ignores white space. If you output a new line character into html, the source gets the new line but, when rendered all white space gets mushed down to a single space.
If you want this rendered on a new line in html ouput, you need to put a <br> after it.

Hello,
I would like to try new line in jstl run_time tag, but I get the following
errors:org.apache.jasper.JasperException: /SimpleBean.jsp(11,0) "${header['User-Agent']+ '\n'}" contains invalid expression(s): javax.servlet.jsp.el.ELException: Encountered "'\n", expected one of [, , , "true", "false", "null", "(", "-", "not", "!", "empty", ]
And my code runs in jsp2.0
Any ideas?

In JSP 2.0: open string literal using " or ', press enter and close string literal :-)

For example:

${fn:replace(text, "
", "<br/>")}

There may be other ways to accomplish this, but here's a method that worked for me. Near the top of the page, I declared a variable holding the newline character:

I was then able to use this variable in an expression down in the "<pre>" block:

Hope this helps someone who stumbles across this page by using the same Google terms as I did.
