rest - smartgwt restdatasource json date validation -

i using spring 3.2 mvc controller , spring-ws create restful web-service. spring controller accepts object files update database correctly , returns json front-end. spring context set message converts json. have unit tests these, know spring controllers working , filing data accordingly.

the error, warning, comes when data/json web-service:

10:05:08.906[error[phonebook]10:05:08.902:xrp3:warn:restdatasource:restuserds:restuserds.userbirthdate:value:-99187200000 failed on validator  {type:"isdate",typecastvalidator:true,_generated:true,defaulterrormessage:"must date."}  com.smartgwt.client.core.jsobject$sgwt_warn:    10:05:08.902:xrp3:warn:restdatasource:restuserds:restuserds.userbirthdate: value: -99187200000 failed on validator: {type: "isdate",typecastvalidator: true,_generated: true,defaulterrormessage: "must date."} @ sun.reflect.nativeconstructoraccessorimpl.newinstance0(native method) @ sun.reflect.nativeconstructoraccessorimpl.newinstance(nativeconstructoraccessorimpl.java:39) @ sun.reflect.delegatingconstructoraccessorimpl.newinstance(delegatingconstructoraccessorimpl.java:27) @ java.lang.reflect.constructor.newinstance(constructor.java:513) @ com.google.gwt.dev.shell.methodadaptor.invoke(methodadaptor.java:105) @ com.google.gwt.dev.shell.methoddispatch.invoke(methoddispatch.java:71) @ com.google.gwt.dev.shell.oophmsessionhandler.invoke(oophmsessionhandler.java:172) @ com.google.gwt.dev.shell.browserchannelserver.reacttomessages(browserchannelserver.java:293) @ com.google.gwt.dev.shell.browserchannelserver.processconnection(browserchannelserver.java:547) @ com.google.gwt.dev.shell.browserchannelserver.run(browserchannelserver.java:364) @ java.lang.thread.run(thread.java:662)

    super.transformresponse(response, request, data);     system.out.println("userdatasource: transformresponse: finish"); }  } 

i can confirm sending data/json fine. have make slight change add attribute sending back. , believe purpose of transformrequest. spring mvc controller receiving update looks like:

@requestmapping(value="/update", method=requestmethod.put,produces="application/json", headers="content-type=application/json") public @responsebody userdto updateuser(@requestbody userdto user) {     system.out.println("usercontroller: start: updateuser: user=" + user);     userentity userentity = service.update(user);     userdto userdto = mapping.mappinguser(userentity);     system.out.println("usercontroller: finish: updateuser: userdto=" + userdto);     return userdto; } 

and can confirm getting valid userdto. when @ transformresponse:

system.out.println("userdatasource: transformresponse: start"); super.transformresponse(response, request, data); system.out.println("userdatasource: transformresponse: finish"); 

i error on first println, haven't done super.transformresponse yet. when @ data coming back, json getting back.

{ "userid":1,  "useractive":true,  "position":{     "id":1,      "active":true,      "code":"admin",      "description":"administrator" },  "username":"demo",  "password":"demo",  "otherpassword":null,  "userfirstname":"demoxxx",  "userlastname":"demoxxx",  "useremail":"tom@tomholmes.netxxx",  "usersecurityquestion1":"meaning of life?xxx",  "usersecurityanswer1":"42xx",  "usersecurityquestion2":"aaaxx",  "usersecurityanswer2":"bbbxx",  "userbirthdate":-99100800000,  "contacts":[     {         "contactid":2,          "userid":1,          "prefix":"mr.",          "firstname":"updated_fn",          "middlename":null,          "lastname":"updated_ln",          "suffix":"jr.",          "address1":"123 main street",          "address2":"apt. 456",          "city":"randolph",          "state":"ma",          "zip":"12345-1234",          "companyid":0,          "enteredby":0,          "entereddate":null,          "editedby":0,          "editeddate":null,          "birthdate":null,          "emails":null,          "phones":null,          "links":null     } ],  "userpositionid":null } 

so ... how fix datasource or transformresponse remove warning? json appears correct, , issue "userbirthdate" when comes long negative number, presume milliseconds epoch. there change can make in json/jackson mapper change how dates formatted?

thanks help!

update 1: provided below helpful, , know not smartgwt or restdatasource issue , strictly how jackson converts java.util.date within object. conversion changes dates negative long number , should have format. using spring 3.2 , using old jackson 1.9.14. now, upgraded jackson 2, , pom.xml uses:

<dependency>     <groupid>com.fasterxml.jackson.core</groupid>     <artifactid>jackson-core</artifactid>     <version>2.1.4</version> </dependency> <dependency>     <groupid>com.fasterxml.jackson.core</groupid>     <artifactid>jackson-databind</artifactid>     <version>2.1.4</version> </dependency> <dependency>     <groupid>com.fasterxml.jackson.core</groupid>     <artifactid>jackson-annotations</artifactid>      <version>2.1.4</version> </dependency> 

within spring-servlext.xml:

   <context:component-scan base-package="com.opensource.restful" />  <bean id="jsonhttpmessageconverter" class="org.springframework.http.converter.json.mappingjackson2httpmessageconverter">      <property name="supportedmediatypes" value="application/json"/>         <property name="objectmapper">              <bean class="com.fasterxml.jackson.databind.objectmapper">                  <property name="dateformat">                  <bean class="java.text.simpledateformat">                  <constructor-arg type="java.lang.string" value="yyyy-mm-dd't'hh:mm:ssz"></constructor-arg>                  </bean>                  </property>              </bean>           </property> </bean>  <bean class="org.springframework.web.servlet.mvc.annotation.annotationmethodhandleradapter">   <property name="messageconverters">       <list>         <ref bean="jsonhttpmessageconverter"/>       </list>   </property> </bean>  <mvc:annotation-driven />     

i have been googling few hours , looking solution uses jackson2 mapper within spring configuration, , after make sure bean definitions correct, userbirthdate still coming negative long. sure configuration can tweaked bit way want, date comes iso format: yyyy-mm-dd't'hh:mm:ssz

thanks helping me closer.

update 2: think did it. stated, upgraded jackson2 understand part of spring 3.2, version of spring using.

the spring-servlet.xml using, , work looks like:

<context:component-scan base-package="com.opensource.restful" />  <mvc:annotation-driven>     <mvc:message-converters register-defaults="true">         <bean class="org.springframework.http.converter.json.mappingjackson2httpmessageconverter">           <property name="objectmapper">              <bean class="com.fasterxml.jackson.databind.objectmapper">                  <property name="dateformat">                  <bean class="java.text.simpledateformat">                  <constructor-arg type="java.lang.string" value="yyyy-mm-dd't'hh:mm:ssz"></constructor-arg>                  </bean>                  </property>              </bean>           </property>         </bean>     </mvc:message-converters> </mvc:annotation-driven>  <bean id="jsonhttpmessageconverter" class="org.springframework.http.converter.json.mappingjackson2httpmessageconverter">     <property name="supportedmediatypes" value="application/json"/> </bean>  <bean class="org.springframework.web.servlet.mvc.annotation.annotationmethodhandleradapter">   <property name="messageconverters">       <list>         <ref bean="jsonhttpmessageconverter" />       </list>   </property> </bean>   <bean id="resttemplate" class="org.springframework.web.client.resttemplate">     <property name="messageconverters">         <list>         <ref bean="jsonhttpmessageconverter" />         </list>     </property> </bean> 

i had add mappingjackson2httpmessageconverter second time because, it's referenced in resttemplate ... if define once, fine. so, maybe can me define spring-servlet.xml better.

anyway, change works , result json date comes as:

 "userbirthdate":"1966-11-03t00:00:00-0500"    

so, that's progress far.

from validation error - defaulterrormessage:"must date"

since birthdatefield datasourcedatefield, userdto.userbirthdate must java.util.date or similar , have date getuserbirthdate().
, constants.user_birthdate must set "userbirthdate".

if above alright, due default serialization of java.util.date object json.
check following additional information on that.
http://java.dzone.com/articles/how-serialize-javautildate (do not use static simpledateformat)
spring 3.1 json date format
jackson2 json iso 8601 date jodatime in spring 3.2rc1

smartgwt works best when following date format used (e.g.- 2013-05-09t00:00:00).
yyyy-mm-dd't'hh:mm:ss

system.out.println() can not used in smartgwt/gwt client side code converted javascript , run inside browser, without jvm.

you won't need use transformresponse() in case.
