java - ValidationHandler not called in metro -

i have sample project test schema validation in jaxws. use metro 2.3.1 , spring in server side.

import javax.jws.webmethod; import javax.jws.webservice; import com.sun.xml.internal.ws.developer.schemavalidation;  @schemavalidation(handler = myerrorhandler.class) @webservice public class testws  {     @webmethod     public string firstmethod()     {         return "hi";     } }   import org.xml.sax.saxparseexception; import org.xml.sax.saxexception; import com.sun.xml.internal.ws.developer.validationerrorhandler;  public class myerrorhandler extends validationerrorhandler  {     public void warning(saxparseexception e) throws saxexception      {         system.out.println("warning");     }      public void error(saxparseexception e) throws saxexception      {         system.out.println("error");     }      public void fatalerror(saxparseexception e) throws saxexception      {         system.out.println("fatal");     } } 

then generate soap message soap ui following:

<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:test="http://test/">    <soapenv:header/>    <soapenv:body>       <test:firstmethod/>    </soapenv:body> </soapenv:envelope> 

and following answer:

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">    <s:body>       <ns2:firstmethodresponse xmlns:ns2="http://test/">          <return>hi</return>       </ns2:firstmethodresponse>    </s:body> </s:envelope> 

this normal soap message request , response when create incorrect soap message following:

<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:test="http://test/">    <soapenv:header/>    <soapenv:body>       <test:firstmethod1/>    </soapenv:body> </soapenv:envelope> 

i append 1 number last of service method : firstmethod create wrong message , after send message server following response :

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">    <s:body>       <s:fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">          <faultcode>s:client</faultcode>          <faultstring>org.xml.sax.saxparseexception; cvc-elt.1: cannot find declaration of element 'test:firstmethod11'.</faultstring>       </s:fault>    </s:body> </s:envelope> 

and in server side following text logged:

error fatal 

but when none soap message such empty-test send server handler class not called , server log messagecreationexception.

or when create soap incorrect message such following changed test tessst , request don't send server handler class not caller.

<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:test="http://test/">    <soapenv:header/>    <soapenv:body>       <tessst:firstmethod/>    </soapenv:body> </soapenv:envelope> 

my question : when validationerrorhandler class called? don't understand obvious. not found clear response in internet.
