I want to create a xml file using SSJS on server. Is there a way to do so? Can anyone please give a sample code to create a xml file on server.

There are quite some ways. The seemingly easiest one is to create a string that looks like XML.
The next one would be the use of Java DOM classes. There is an article describing it.
Finally you can use SAX with a little helper class
Let us know how it goes.
Update: This would be my version of @Michael's code sample:
<?xml version="1.0" encoding="UTF-8"?>
<!-- XPage which is not rendered but returns data like XML, JSON, etc. -->
<!-- More: http://www.wissel.net/blog/d6plinks/shwl-7mgfbn -->
<xp:view xmlns:xp="http://www.ibm.com/xsp/core" rendered="false">
<xp:this.beforeRenderResponse><![CDATA[#{javascript:try {
var out = facesContext.getOutputStream();
var exCon = facesContext.getExternalContext();
var response = exCon.getResponse(); // get the response context
// set content type, e.g. ...
response.setContentType("text/xml");
// set caching option
response.setHeader("Cache-Control", "no-cache");
// write XML output ...
var result = new biz.taoconsulting.xmltools.SimpleXMLDoc();
result.setOut(out);
result.openTag("result");
result.dateTag("created", new java.util.Date());
result.addSimpleTag("Author",@UserName);
result.openTag("FruitList");
result.addComment("Stephan really likes the fruits example");
var attributes = new java.util.HashMap();
attributes.add("name","Durian");
attributes.add("color","white");
attributes.add("taste","Don't ask");
result.addEmptyTag("fruit",attributes);
result.closeDocument();
// close the output
exCon.responseComplete();
out.close();
} catch (e) {
print(e.toString());
}}]]>
</xp:this.beforeRenderResponse>
</xp:view>
Note the differences here:
- I use the beforeRenderResponse event
- Access to outputStream instead of writer (stream is not accessible in the afterRenderResponse event)
- set the response complete to stop the page from further output, so you can simply type comments on the page what it does
- use of the helper class
What seems a little odd when you read the source of the helper class: why not use the output stream in the constructor, so you won't miss it? - I would today add a second constructor with that, but the parameterless constructor allow me to define that class as a managed bean if I fancy that.
to "render" XML in a String as @Stefan suggested I would use the XAgent approach:
<?xml version="1.0" encoding="UTF-8"?>
<!-- XPage which is not rendered but returns data like XML, JSON, etc. -->
<!-- More: http://www.wissel.net/blog/d6plinks/shwl-7mgfbn -->
<xp:view xmlns:xp="http://www.ibm.com/xsp/core" rendered="false">
<xp:this.afterRenderResponse><![CDATA[#{javascript:try {
var writer = facesContext.getResponseWriter(), // get a writer object
response = facesContext.getExternalContext().getResponse(); // get the response context
// set content type, e.g. ...
response.setContentType("text/xml");
// set caching option
response.setHeader("Cache-Control", "no-cache");
// write XML output ...
writer.write(
'<?xml version="1.0"?>\n'
+ '<root>\n'
+ '<entity>Example Content</entity>\n'
+ '</root>\n'
);
// close the stream
writer.endDocument();
} catch (e) {
print(e.toString());
}}]]>
</xp:this.afterRenderResponse>
<xp:this.resources>
<xp:script src="/XBAN.jss" clientSide="false"></xp:script>
</xp:this.resources>

Simply put his code into a newly created XPage and test it. Modify the lines in writer.write()
to fit to your needs.
