Pass values to XML

[Rajkumar balakrishnan]

I am using Jersey to implement REST Web Services in my project. Currently i am trying a simple application where i post values from a FORM and process it to produce a XML output.

The Resource code is

	
        @POST
	@Produces(MediaType.TEXT_XML)
	@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
	public void newService(
			@FormParam("id") String id,
			@FormParam("summary") String summary,
			@FormParam("description") String description,
			@Context HttpServletResponse servletResponse
	) throws IOException {
		Bean bean = new Bean(id,summary);
		if (description!=null){
			bean.setDescription(description);
		}
                // Some DAO Processing
		BeanDao.instance.getModel().put(id, bean);
		
		URI uri = uriInfo.getAbsolutePathBuilder().path(id).build();
		Response.created(uri).build();
				
		servletResponse.sendRedirect("../create_output_xml.xml");
	}
	

The create_output_xml.xml page is

<?xml version="1.0" encoding="UTF-8"?>
<values>
	<value>
		<description>${description}</description>
		<id>${id}</id>
		<summary>${summary}</summary>
	</value>
</values>

When i try to run it, the values get posted and XML page is displayed but with no values.
I knew that i didn't pass the value, but i dont know how to pass these values to the xml so that it'll be displayed in output instead of ${}.

Hi!
Have you tried setting the corresponding attributes in the servlet request object?
See the javax.servlet.ServletRequest interface API documentation for details on how to set attributes in the reqeust obejct.

So do i need to create XML using JAXB and pass it to client?

Hi!
I came to think of something:
The output page is not a JSP, so I don't think things like ${description} and ${summary} will be substituted even if you have the corresponding attributes set in the request.
You should use some templating framework, like Apache Tiles http://tiles.apache.org/, or some other mechanism to replace the placeholders with values.
Best wishes!

Thanks for the reply...

I got further simpler way to achieve that. Just created a bean with all values to be added in XML and pass it as a Object. Then, the Jersey will take care of the rest. It created the XML!!!
