For returning the method response in XML form we need to use JAXB API.
JAXB API is inside the JDK-1.6 and we can use it directly by putting the @XMLRootElement as an annotation of the POJO returned object.
package com; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name="response") public class Response { String specVersion; Status status; public String getSpecVersion() { return specVersion; } public void setSpecVersion(String specVersion) { this.specVersion = specVersion; } public Status getStatus() { return status; } public void setStatus(Status status) { this.status = status; } } package com; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name="status") public class Status { int code; String mnemo; public int getCode() { return code; } public void setCode(int code) { this.code = code; } public String getMnemo() { return mnemo; } public void setMnemo(String mnemo) { this.mnemo = mnemo; } }
while hit the URL , we will get the response in xml form like as follows:
http://localhost:8080/Mail/getVersion
<response> <specVersion>34c</specVersion> <status> <code>100</code> <mnemo>OK</mnemo> </status> </response>
