Hi,
After a very good help from Mind Bridge, figured out what the problem is.
Just posting here, in case somebody encounters the same problem.
In the Tomcat lib, xalan jar file is not present and this is throwing an
error "javax.xml.transform.TransformerFactoryConfigurationError: Provider
org.apache.xalan.processor.TransformerFactoryImpl not found
at javax.xml.transform.TransformerFactory.newInstance(Unknown
Source)
at
org.mb.tapestry.xtile.XTileService.generateOutputString(XTileService.java:10
4)"
I placed the jar and it is working fine.
Excellent help and good work from the people over here.
Thanks once again.
Surya

Subject: RE: Using XTiles component
Hi,
Sorry for a bit vague.
Configuration: JDK1.5, Tomcat 5.0, Tapestry 3.0.3, IE 6+, Firefox 1+,
Eclipse 3M7, Spindle, X-Tiles jar available from t-deli.com
Trying to replicate the X-Tiles demo given at given at T-Deli.com on the
local machine using above configuration.
Problem: I downloaded the source code given at the t-deli site to display a
list of countries onkeyup script using Ajax. The source I am using is given
below:
***********************************
Application file:
<application name="AjaxTest">
<library id="xtile"
specification-path="/org/mb/tapestry/xtile/xtile.library"/>
</application>
************************************
Home Page
<html jwcid="@Shell" title="XTile example">
<body jwcid="@Body">
Start typing the name of a country in the field below. <br>
The page will connect to the server and ask for possible completions.
<p>
<form name="f">
<table cellspacing="0" cellpadding="0">
<tr>
<td>Country: </td>
<td><input type="text" style="width: 200px"
onkeyup="sendValue(this.value)"/></td>
</tr>
<tr>
<td></td>
<td><textarea name="comps" rows="10" style="width: 200px"
></textarea></td>
</tr>
</table>
</form>
<span jwcid="@xtile:XTile" listener="ognl:listeners.handleCallback"
sendName="sendValue" receiveName="receiveCompletions"/>
<script>
function receiveCompletions(arr) {
document.f.comps.value = arr.join("\n");
}
</script>
<span jwcid="@xtile:Timeout"/>
</body>
</html>
****************************************************************
Home.java
package examples;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.LinkedHashSet;
import java.util.List;
import java.util.Locale;
import java.util.Set;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.html.BasePage;
public class Home extends BasePage
{
private final static int MAX_COMPLETIONS = 10;
private static Set countries = new LinkedHashSet();
static {
System.out.println("Entered in static block");
Locale[] locales = Locale.getAvailableLocales();
for (int i = 0; i < locales.length; i++) {
String country = locales[i].getDisplayCountry();
if (country != null) {
//System.out.println("Country:"+country);
countries.add(country);
}
}
}
private String[] findCompletions(String typed)
{
System.out.println("Entered in findCompletions and
typed:"+typed);
if (typed.equals(""))
return null;
typed = typed.toLowerCase();
List completions = new ArrayList();
for (Iterator it = countries.iterator(); it.hasNext();) {
String country = (String) it.next();
//System.out.println("Country:"+country);
if (country.toLowerCase().startsWith(typed)){
System.out.println("Added
country:"+country);
completions.add(country);
}
if (completions.size() == MAX_COMPLETIONS)
break;
}
Collections.sort(completions);
return (String[]) completions.toArray(new
String[completions.size()]);
}
public void handleCallback(IRequestCycle cycle)
{
System.out.println("Entered in handleCallback");
Object[] params = cycle.getServiceParameters();
if (params.length == 0) return;
String typed = params[0].toString();
String[] ret = findCompletions(typed);
for(int i=0; i<ret.length; i++){
System.out.println("return list:"+ret[i]);
}
cycle.setServiceParameters(ret);
}
}
******************************************************
As shown in the source, the print statements are printing the list of
countries in the handleCallback and the returned String[] array ret is
correctly set to the service parameters, when I am typing a key but the list
is not shown in the text area in the html page.
Thanks in advance.

Can you be more specific? It's hard to answer such a general question.
