line 1 +CRLF ("\r\n") + line 2 + CRLF ("\r\n") .....
and the text out put need like this:
__
line 1
line 2
line 3
...
- JSF code --
<h:inputTextarea styleClass="inputTextarea" id="textarea1"
cols="50" rows="10" value="#{MyBean.lines}" readonly="true" style="overflow:hidden">
</h:inputTextarea>
MyBean.java
public String getLines(){
// get lines String
return lines;
}

Hi
It seems that ur problem is due to CRLF("\r\n")function
if ur function return string like this ( return string from method binded in <h:inputTextArea> value Attribute)
line 1 +"\r\n" + line 2 + "\r\n".....
it will definetly work properly.
and the output will be according to ur requirement
# 2
well why not make use of System.getProperty("line.seperator") instead of CRLF("\r\n")NOTE:System.getProperty("line.seperator") is more native.. just rethink while applying it.
# 3
if this CRLF is already used and stored in database then 'CRLF(' and ')' sholuld be removed from line instead of getting System.lineSeparator , beacause this is already stored in database.
Yout option can be used if database can be repopulated.
here System.lineSeparator can be used instead of CRLF function
# 4
I don't think the problem should be with the choice of line separator. First, the issue occurs on the client, not the server. So using the line separator property from System will give you the separator on the server, not the client.
Second, the problem is coming from JavaScript; I don't believe that the inputTextArea component renders the value within a JavaScript constant.
So what I would do here is view the source in the browser and look at what is happening on line 963. If you can, post the code here.
# 5
I had tried System.getProperty("line.seperator"), got same error, I looked on line 963 it is because the CRLF there since if I remove it it is OK no error, BUT if I remove the CRLF after from database, how can I out put the lines like within the <h:inputTextarea>, Does anyone know a solution? Thanks for your help...!

Please post the generated code that causes the error. I am willing to bet it has nothing to do with the inputTextarea tag.

Why not substitute a
for CRLF. BTW I would avoid using markup in value of text area. Note: JSF documentation
Creates a user input text area for multiple lines of text. Displays an HTML <textarea> element with a name attribute set to the component's client ID and a body holding the component's value.

Thanks all for your kind reply !
not working, I have the output in <h:inputTextarea> in one line like this :
line1 <br> line2
......
Can <h:inputTextarea> automatically separate the text line by line if any special markup there such as CRLF .... if not, what can I use ? I was think using dataTable to display a list of seperated strings , but seems not workable...
Thanks in advance !

You are seriously barking up the wrong tree. Post the generated code.

Try CSS..textAreaStyle {white-space: pre;}
# 11
I think your use of inputTexaArea to display multiple lines is correct although I haven't tried to use inputTextArea with styeClass and style attributes.
The problem might be something to do with the original string, "lines", as it gave this error.
Error: Unterminated string constant
You might need to check the set property function of the 'lines' property to make sure there is end of line character for each line.
