Marshalling plumbing - off base

[Mimi Tam]

Hi,

I am using Marshaller/UnMarshaller and @RequestBody and @ResponseBody to render HTTP messages. Both request and response bodies have an XML string.

After the request body has been retrieved using @RequestBody to a POJO class object, I need to process the XML data and create an HTTPResponse with an XML string to send back to the originating URL.

Then, subsequently display the XML response data on a web page.

My question is:

In my controller using MVC processing an HTTPRequest POST method, what should I return? I have no View. I just want to return the HTTPResponse message with a new XML string send back to the Requester and then "render"/display the HTTPResponse message on a web page.

My web service sends requests and receives responses, hence need to handle both.

I am new to this, please help.

In my controller:

@RequestMapping(value = "/httpmsg", method = RequestMethod.PUT)
public String create(@RequestBody HTTPMsg httpmsg) {
System.out.println("HTTP Message PUT: " + httpmsg);
return "httpmsg";
}
@RequestMapping(value = "/httpmsg", method = RequestMethod.POST)
public String create(@RequestBody HTTPMsg httpmsg, ModelMap modelMap) {
System.out.println("HTTPMsg: " + httpmsg);
if (httpmsg == null) throw new IllegalArgumentException("An HTTP request is required");
return "redirect:/httpmsg/";
}

@RequestMapping(value = "/httpmsg", method = RequestMethod.POST)
public String createRsp(@ResponseBody HTTPMsg httpmsg, ModelMap modelMap) {
System.out.println("HTTPMsg: " + httpmsg);
return "redirect:/httpmsg/";
}

// Provides a Form to enter Request parameters
@RequestMapping(value = "/httpmsg/form", method = RequestMethod.GET)
public String createForm(ModelMap modelMap) {
modelMap.addAttribute("httpmsg", new HTTPMsg());
return "httpmsg/create";
}....

In my webmvc_config.xml:

....<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>com.bzinc.demoBackup.domain.HTTPMsg</value>
</list>
</property>
<!-- <property name="schema" value="classpathrg/springframework/oxm/schema.xsd"/> -->
</bean>

<bean class="oe]rg.springframework.web.servlet.mvc.annotat ion.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="marshallingHttpMessageConverter"/>
</list>
</property>
</bean>

<bean id="marshallingHttpMessageConverter"
class="org.springframework.http.converter.xml.Mars hallingHttpMessageConverter">
<property name="marshaller" ref="marshaller" />
<property name="unmarshaller" ref="marshaller" />
</bean>...

How off-base am I on the plumbing above? Please point out problems or the right way to do it.

I'd greatly appreciate your help.
