How to unmarshal this type of xml in java -

i new rest api. have xml output need unmarshal. below xml output:

<dsml>     <entries>         <entry dn="uid=7686,c=in,ou=pages,o=example.com">             <att name="uid">                 <value>7568766</value>             </att>             <att name="email">                 <value>new@gmail.com</value>             </att>             <att name="callname">                 <value>john</value>             </att>         </entry>         <entry dn="uid=7689,c=in,ou=pages,o=example.com">             <att name="uid">                 <value>7678766</value>             </att>             <att name="callname">                 <value>mike</value>             </att>         </entry>         <entry dn="uid=7690,c=in,ou=pages,o=example.com">             <att name="uid">                 <value>75858766</value>             </att>             <att name="email">                 <value>old@gmail.com</value>             </att>             <att name="callname">                 <value>rahul</value>             </att>         </entry>     </entries> </dsml> 

the actual xml output has total 37 entries. below model class:

@xmlaccessortype(xmlaccesstype.field) @xmlrootelement(name = "user") public class user implements serializable{     private static final long serialversionuid = 1l;      @xmlelement(name = "uid")     private int uid;      @xmlelement(name = "callname")     private string callname;      @xmlelement(name = "email")     private string email;      public int getid() {         return uid;     }     public void setid(int uid) {         this.uid = uid;     }     public string getfirstname() {         return callname;     }     public void setfirstname(string callname) {         this.callname = callname;     }     public string getmail() {         return email;     }     public void setmail(string email) {         this.email = email;     } } 

below rest api class code:

public class usingrestapi {     public static void main(string[] args)      {         try         {             url url = new url("www.example.com");             httpurlconnection conn = (httpurlconnection) url.openconnection();             conn.setrequestmethod("get");             conn.setrequestproperty("accept", "application/xml");              if (conn.getresponsecode() != 200)              {                 throw new runtimeexception("failed : http error code : " + conn.getresponsecode());             }              bufferedreader br = new bufferedreader(new inputstreamreader((conn.getinputstream())));             string apioutput="",temp="";             while ((apioutput = br.readline()) != null) {                 temp += apioutput;                 system.out.println(apioutput);             }               jaxbcontext jaxbcontext = jaxbcontext.newinstance(user.class);             unmarshaller jaxbunmarshaller = jaxbcontext.createunmarshaller();             user user = (user) jaxbunmarshaller.unmarshal(new stringreader(temp));              system.out.println(user.getid());             system.out.println(user.getfirstname());             system.out.println(user.getmail());          } catch (malformedurlexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         } catch (jaxbexception e) {             e.printstacktrace();         }     } } 

while executing code, getting error

javax.xml.bind.unmarshalexception - linked exception: [org.xml.sax.saxparseexception; linenumber: 1; columnnumber: 110; external dtd: failed read external dtd 'dsml.dtd', because 'http' access not allowed due restriction set accessexternaldtd property.]

i have tried changing propert access_external_dtd true, gave error:

javax.xml.bind.propertyexception: name: http://javax.xml.xmlconstants/property/accessexternaldtd value: true     @ javax.xml.bind.helpers.abstractunmarshallerimpl.setproperty(unknown source)     @ com.sun.xml.internal.bind.v2.runtime.unmarshaller.unmarshallerimpl.setproperty(unknown source)     @ usingrestapi.main(usingrestapi.java:60) 

why donot save xml in file , pass unmarshal

new version_:

user user = (user) jaxbunmarshaller.unmarshal(new file("c:/temp/user.xml") );//file path 

it not give errors.
