Yes the code works when calling it from a Java application as opposed to
when it is deployed into Axis.
Here is the relevant method from MailHelperFactory (the business logic
loader if you will)
public static IMailHelper loadClass( String mailHelperClassName ) {
Class mailHelperGenClass = null;
IMailHelper mailHelper = null;
try {
// instruct the class loader to load the MailHelper
implementation
//mailHelperGenClass = createClass(mailHelperClassName);
mailHelperGenClass = Class.forName( mailHelperClassName ); //
<-- using what you suggested
} catch (java.lang.Exception e) {
e.printStackTrace();
throw new RuntimeException(mailHelperClassName + " Not Found");
}
try {
// try to instantiate the MailHelper class
mailHelper = (IMailHelper) mailHelperGenClass.newInstance();
return mailHelper;
} catch (java.lang.Exception e) {
e.printStackTrace();
throw new RuntimeException(mailHelperClassName + " cannot create
instance");
}
}
now in my test application I call:
package au.gov.abs.webservices.BpmsMessageSendingService;
import au.gov.abs.Helpers.MailHelper.IMailHelper;
import au.gov.abs.Helpers.MailHelper.MailHelperFactory;
public class Test
{
/**
* @param args
*/
public static void main( String[] args )
{
// TODO Auto-generated method stub
IMailHelper mh =
MailHelperFactory.loadClass("au.gov.abs.Helpers.MailHelper.NotesMailHelper");
System.out.println( mh.toString() );
}
}
That works. In my Web service:
public void sendEvent(java.lang.String headers, boolean sign,
java.lang.String invoker, java.lang.String eventname, java.lang.String
discriminator, java.lang.String eventPayload) throws
java.rmi.RemoteException
{
IMailHelper mh =
MailHelperFactory.loadClass("au.gov.abs.Helpers.MailHelper.NotesMailHelper");
System.out.println( mh.toString() );
}
Doesn't work. Even when I wrap the loadClass call in the Web service with a
try/catch block the exception doesn't get caught.
