Spring MVC RESTful interface

I'm new to spring and I would like to create RESTful interface. I can't get simple sample code working and I can't figure out where is the issue...

The below code triggers error:

• Exception reading manifest from http://localhost:8080/myTestApp/test: the manifest may not be valid or the file could not be opened.
• Source: System.Deployment

The code:

@RequestMapping(method=RequestMethod.GET, value="/test")
@ResponseBody
public String test(@RequestBody String body){
    String testString = test.CreateXml();
    return testString;
    //return "home";
}

If I first launch the project in server with the below code

@RequestMapping(method=RequestMethod.GET, value="/test")
//@ResponseBody
public String test(@RequestBody String body){
    String testString = test.CreateXml();
    //return testString;
    return "home";
}

Then I uncomment "@ResponseBody" and "return testString" and put comment for "return "home"" line while the server is up and running. So the code looks precisely like the previous what didn't worked. After the changes to code I press Save and the new code is delivered to server on fly. After these changes the "test" interface works. If I restart server I again receive error.

I'm using "Spring Tool Suite 3.4.0" and as servers tried "VMware Fabric tc Server Developer Edition v2.9" and "Tomcat v7". With both servers there is the same issue so the cause should be somewhere in spring configuration. Could anyone please help?

Below I have attached error log

The "Test" is sample code for REST interface. Currently it generates "dummy" xml. Below is generated dummy xml.

<root>
<!--This is a comment-->
<test name="value">My node value</test>
</root>

Below is code for the "test"

public class test {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        CreateXml();
    }
    public static String CreateXml() {
        String xmlString = null;
            try {

                //Creating an empty XML Document
                DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
                DocumentBuilder docBuilder = dbfac.newDocumentBuilder();
                Document doc = docBuilder.newDocument();

                //Creating the XML tree

                //create the root element and add it to the document
                Element root = doc.createElement("root");
                doc.appendChild(root);

                //create a comment and put it in the root element
                Comment comment = doc.createComment("This is a comment");
                root.appendChild(comment);

                //create child element, add an attribute, and add to root
                Element child = doc.createElement("test");
                child.setAttribute("name", "value");
                root.appendChild(child);

                //add a text element to the child
                Text text = doc.createTextNode("My node value");
                child.appendChild(text);

                //Output the XML to a string

                //set up a transformer
                TransformerFactory transfac = TransformerFactory.newInstance();
                Transformer trans = transfac.newTransformer();
                trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
                trans.setOutputProperty(OutputKeys.INDENT, "yes");

                //create string from xml tree
                StringWriter sw = new StringWriter();
                StreamResult result = new StreamResult(sw);
                DOMSource source = new DOMSource(doc);
                trans.transform(source, result);
                xmlString = sw.toString();

                //print xml
                System.out.println("xml output :\n\n" + xmlString);

            } catch (Exception e) {
                System.out.println(e);
            }
            return xmlString;
        }
}

I haven't touched context xml and it was auto generated. Below is the servlet-context.xml
