beginner q: classnotfoundexception using DynamicClientFactory

Hi folks,
Having some diffs with the DynamicClientFactory.
On following the example like so:
[code]
        ClassLoader classLoader =
Thread.currentThread().getContextClassLoader(); 
        DynamicClientFactory dcf = DynamicClientFactory.newInstance();
        Client client =
dcf.createClient("http://www.webservicex.net/CurrencyConvertor.asmx?wsdl",
classLoader);
         
        Object rate =
classLoader.loadClass("net.webservicex.ConversionRate").newInstance();
         
        Method m1 = rate.getClass().getMethod("setFromCurrency",
String.class);
        Method m2 = rate.getClass().getMethod("setToCurrency",
String.class);
        m1.invoke(rate, "GBP");
        m2.invoke(rate, "USD");         
        Object result = client.invoke("ConversionRate", rate);
        System.out.println("result=" + result);

[/code]

I get a classnotfoundexception on the loadClass bit to create the object.
CXF seems to be creating the necessary objects:
[code]
25-Jul-2007 12:10:34 org.apache.cxf.endpoint.dynamic.DynamicClientFactory
outputDebug
INFO: Created classes: net.webservicex.ConversionRate,
net.webservicex.ConversionRateResponse, net.webservicex.Currency,
net.webservicex.ObjectFactory
[/code]

but they don't seem to be available in the classloader.
Any thoughts?

thanks,
Marty

Hi,

I just went through the DynamicClientFactory code, and found your code got class loader a little earlier.
When the DynamicClientFactory create the client , it will setup the classpath to load the generated class.

You just need to use the thread's ContextClassLoader after the dcf.createClient to load the jaxb class.

The codes could be:

[code]
        ClassLoader classLoader =
Thread.currentThread().getContextClassLoader(); 
        DynamicClientFactory dcf = DynamicClientFactory.newInstance();
        Client client =
dcf.createClient("http://www.webservicex.net/CurrencyConvertor.asmx?wsdl",
classLoader);
         
        Object rate =
Thread.currentThread().getContextClassLoader().loadClass("net.webservicex.ConversionRate").newInstance();
         
        Method m1 = rate.getClass().getMethod("setFromCurrency",
String.class);
        Method m2 = rate.getClass().getMethod("setToCurrency",
String.class);
        m1.invoke(rate, "GBP");
        m2.invoke(rate, "USD");         
        Object result = client.invoke("ConversionRate", rate);
        System.out.println("result=" + result);

[/code]

Willem.
