java - extended classes from jar does not work -


i've project in xmlbeans 2.6.0 jars referenced , added classpath. create class similar below:

import org.apache.xmlbeans.schematype; import org.apache.xmlbeans.impl.values.xmlcomplexcontentimpl; import org.apache.xmlbeans.impl.values.xmlobjectbase;  public class test3 extends xmlcomplexcontentimpl {      public test3(schematype type) {         super(type);     }      public void hello() {          // below method present in xmlobjectbase extended xmlcomplexcontentimpl         // xmlobjectbase , xmlcomplexcontentimpl part of jar         generatedsetterhelperimpl(null, null, 0, (short)2);      }  }

and when create instance of test3 , call hello() method, error nosuchmethoderror thrown. not lookup extended class method instead searches method in test3.

java.lang.nosuchmethoderror: com.voxify.vui.action.test3.generatedsetterhelperimpl(lorg/apache/xmlbeans/xmlobject;ljavax/xml/namespace/qname;is)lorg/apache/xmlbeans/xmlobject;

these errors arise jar version conflict. may have different jar version @ compile time , run time.one way check remove jar think getting referred to. way might find different version of same jar in classpath getting loaded.
