I've tried everything short of looking into JBoss's source code to see why it's throwing the exception: Here's a portion of the call stack in the exception: javax.xml.ws.WebServiceException: SEI is missing @WebService annotation: interface ws.currencyconverter.CurrencyWS at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.assertSEIConstraints(ServiceDelegateImpl.java:287) at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.getPort(ServiceDelegateImpl.java:180) at javax.xml.ws.Service.getPort(Service.java:116) at ws.currencyconverter.CurrencyWSService.getCurrencyWSPort(CurrencyWSService.java:54) at commands.ConvertCurrencyCommand.invokeWebService(ConvertCurrencyCommand.java:76) at commands.ConvertCurrencyCommand.execute(ConvertCurrencyCommand.java:59) at web.CurrencyConverterServlet.process(CurrencyConverterServlet.java:52) Can someone help? If you think you can help but need more info, please reply and I'll post any additional info needed.
