Thanks Daniel for your input in this matter. Yes my original intent was for this to be a CXF client, LOL so I do want to include / invoke CXF. To that end, I scoured the internet for guidance regarding the particular approach I’m taking to build a client application, i.e., a standalone Java Spring application running as a managed (NonStop PATHWAY) server. The HP NonStop environment is well suited to this approach as the Java program runs under the native process management subsystem (PATHWAY) which manages threading, albeit heavy-weight threading. The question is, how do I include CXF in the mix. Based on my scouring, I think I need to do the following.
The current Spring application context (XML) looks like this… <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd";> <bean id="RDDS" class="com.telus.health.pdd.business.RddsReqProcessor"> <property name="demoSs" ref="demosoapservice"></property> </bean> <bean id="demosoapservice" class="com.telus.health.pdd.asyncdemo.AsyncDemoService"> <constructor-arg type="java.net.URL" value="http://<ip_addr>:<port_no>/nssoap01/casz/jadmin/pway-wsdl/CASZ_SoapPW_AsyncDemo.wsdl"/> </bean> </beans> It should look more like this… <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"; http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd";<http://cxf.apache.org/schemas/jaxws.xsd%22>> <bean id="RDDS" class="com.telus.health.pdd.business.RddsReqProcessor"> <property name="demoSs" ref="demosoapservice"></property> </bean> <bean id="demosoapservice" class="com.telus.health.pdd.asyncdemo.AsyncDemoService"> <constructor-arg type="java.net.URL" value="http://<ip_addr>:<port_no>/nssoap01/casz/jadmin/pway-wsdl/CASZ_SoapPW_AsyncDemo.wsdl"/> </bean> <bean id="proxyFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value=" com.telus.health.pdd.asyncdemo.AsyncDemoService "/> <property name="address" value="http://<ip_addr>:<port_no>/servlets/PddAsyncWS/services/control"/<http://%3cip_addr%3e:%3cport_no%3e/servlets/PddAsyncWS/services/control%22/>> </bean> <bean id=" demosoapservice " class="com.telus.health.pdd.asyncdemo.AsyncDemoService" factory-bean="proxyFactory" factory-method="create"/> </beans> Cheers David From: Daniel Kulp [via CXF] [mailto:[email protected]] Sent: April 11, 2014 12:57 PM To: David Wiseman Subject: Re: Getting java.lang.ClassCast Exception: javax.xml.ws.Holder cannot be cast to java.lang.String On Apr 11, 2014, at 11:53 AM, David Wiseman <[hidden email]</user/SendEmail.jtp?type=node&node=5742721&i=0>> wrote: > > Good point... you are correct, there is nothing about CXF in my classpath > (see below).

Well, CXF is certainly less buggy around the more complex use cases and is much more secure as well. > I could be totally wrong but I don't think my casting exception is related > to the jaxws implementation. Actually, it is. I’m not sure if the RI’s async methods handle the holder things at all. I would definitely suggest trying with CXF. Either that or try generating “Bare” style methods so the holders are not there.
