java jar file - not able to fine java file when trying to create a service

Hi:

I created a java class and exported it as a jar.  I then created an emml file to use the jar file.  I am able to run the emml file from eclipse fine (I added the jar file to the server classpath settings).

I need to create a service from this EMML file.  I pasted the jar file into

...\Presto2.7.0\server\apache-tomcat-5.5.20\webapps\presto\WEB-INF\lib

published the emmil file using studio.

From the service explorer I am able to view the service, when I click on it and try and make a mashlet using the service, it seems as if it is not able to find the jar file.

I receive the following error:

"Error execution Mashup Script : Error executing script : TypeError: [JavaPackage com.acn.financialforecasting.reader.MyTimeAndExpenseReader] is not a function, it is org.mozilla.javascript.NativeJavaPackage. (#4)

To me this basically means that it cannot find the jar file.  It seems like I am missing a step.  I know my code works fine as i was able to test it using studio, but here is the test code anyway:

 mashup name="MyTimeAndExpense2"

xmlns="http://www.jackbe.com/2008-03-01/EMMLSchema"

../xsd/EMMLSpec.xsd"

xsi:schemaLocation="http://www.jackbe.com/2008-03-01/EMMLSchema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<

<

output name="result" type="string"/>script type="text/javascript">

<![CDATA[

var item2 = new Packages.com.acn.financialforecasting.reader.MyTimeAndExpenseReader();

var boList = item2.getBOList();

var tempXMLString;

var xmlString = '';

for (var i = 0; i < 10; i++){

var temp = boList.get(i);

tempXMLString = Packages.com.jackbe.jbp.transform.DataTransformer.javaToXml(temp)

xmlString = tempXMLString;

}

result = Packages.com.jackbe.jbp.sas.nsd.NSDUtil.XMLToDOM(xmlString);

</

</

]]>script>mashup>

any help on how to incorporate jar files into services would be of great help...

thanks,
