hibernate - java.lang.NoSuchMethodException: Unknown property 'language' on class 'class java.lang.Class' -

im getting follwoing error:

java.lang.nosuchmethodexception: unknown property 'language' on class 'class java.lang.class' 

rest call used : /test/rest/languages/insertobj/japanese/swedish%206

i using : org.apache.commons.beanutils.propertyutils;

i had specified property 'language' in languages class im not sure why throwing error. works when declare such :

languages lanobj = new lanaguages();

//languages class

public class languages implements java.io.serializable {     private string language;     private string displayname;  public languages() {         this.language = null;         this.displayname = null;     }   public languages(string language, string displayname) {     this.language = language;     this.displayname = displayname; }  public void setlanguageid(long languageid) {     this.languageid = languageid; }  @column(name = "language", nullable = false, length = 50) public string getlanguage() {     return this.language; }  public void setlanguage(string language) {     this.language = language; }  @column(name = "displayname", nullable = false, length = 50) public string getdisplayname() {     return this.displayname; }  public void setdisplayname(string displayname) {     this.displayname = displayname; }  }

setproperty needs instance whereas passing class, see documentation

class<?> c = class.forname("com.test."+id); language language = (language)c.newinstance(); propertyutils.setproperty(language , "language",language_id); 

either specificially cast language or else can leave object

object object  = class.forname("com.test."+id).newinstance(); propertyutils.setproperty(object, "language",language_id);
