I am trying to use Ajax (DWR framework) within Struts Framework.
Per DWR Documentation, they have added StrutsCreator in current version to
support struts framework. I just do not know how to use / integrate it. I am
new to AJAX. Can anyone please help me out.
When I try to make a dwr call on jsp, I get javascript error [object error]
and on the console I can see error -
uk.ltd.getahead.dwr.util.CommonsLoggingOutput error SEVERE: No converter
found for org.apache.struts.action.ActionServletWrapper .
You probably don't actually want to be sending or receiving the
ActionServletWrapper in your remote calls, so you probably want to
take a step back and assess your remote object's API.
You might also want to review the DWR documentation on Converters:
http://getahead.ltd.uk/dwr/server/dwrxml/converters
In short, it requires you to show it how to marshall any object
except a few core types to and from JavaScript, so that it knows
which properties to expose and which to protect.

Please help!

My dwr.xml -
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr10.dtd";>
<dwr>
<init>
<creator id="struts" class="uk.ltd.getahead.dwr.create.StrutsCreator"/>
</init>
<allow>
<create creator="struts" javascript="BatchTransDetailActFrm">
<param name="formBean" value="BatchTransDetailActFrm"/>
<include method="addTransaction"/>
</create>
</allow>
</dwr>
---------------------------------------------------------------------------
My Javascript from JSP -
<script language="javascript1.2" src="<sys:write propertyName='
apache.root.alias'/>/dwr/interface/BatchTransDetailActFrm.js"></script>
<script language="javascript1.2 " src="<sys:write propertyName='
apache.root.alias'/>/dwr/engine.js"></script>
<script language=" javascript1.2" src="<sys:write propertyName='
apache.root.alias'/>/dwr/util.js"></script>
<!-- This is how we access javascript and css otherwise -->
<script language="javascript1.2" src="<system:getServer propertyName='
apache.base.name '/>/javascript/Validation.js"></script>
<link href="<system:getServer
propertyName='apache.base.name'/>/stylesheet/greatvic.css"
rel="stylesheet" type="text/css">
<script>
function addTrans(){
var acctType= document.getElementById("acctType").value;
var acctNum= document.getElementById("acctNum").value;
var vletters= document.getElementById("vletters").value;
var suffix= document.getElementById("suffix").value;
var amount= document.getElementById("amount").value;
var checkType= document.getElementById("checkType").value;
BatchTransDetailActFrm.addTransaction (fillTable, acctType, acctNum,
vletters, suffix, checkType,amount); $("resultTable").style.display = '';
}
function fillTable(transactionBeans) {
DWRUtil.addRows("transactionbody", transactionBeans, [ getBatchNum,
getAcctType, getAcctNum, getVletters, getSuffix, getCheckType, getAmount ]);
}
---------------------------------------------------------------------------
When I make call to addTrans function I get "[Object Error]" javascript
popup. And on server I see Error -
uk.ltd.getahead.dwr.util.CommonsLoggingOutput error SEVERE: No converter
found for org.apache.struts.action.ActionServletWrapper.
------------------------------ ---------------------------------------------
Also while loading that jsp page initially on the server I see error -
Dec 5, 2005 2:37:49 PM uk.ltd.getahead.dwr.util.CommonsLoggingOutput error
SEVERE: Error loading class for creator
'StrutsCreator[BatchTransDetailActFrm]'.

at org.apache.struts.util.ModuleUtils.getModuleConfig(
ModuleUtils.java:127)
at org.apache.struts.util.RequestUtils.getModuleConfig(
RequestUtils.java:1110)
