i know question has been asked many times, although tried has been said still have issue. i'm trying generate simple json response working. right 406 not acceptable error. tomcat says "the resource identified request capable of generating responses characteristics not acceptable according request "accept" headers." in tomcat/lib have jackson jars. i'm using spring 1.1.0 tomcat 7. addedd dependencies in pom.xml:
<dependencies> <dependency> <groupid>com.fasterxml.jackson.core</groupid> <artifactid>jackson-core</artifactid> <version>2.4.1</version> </dependency> <dependency> <groupid>com.fasterxml.jackson.core</groupid> <artifactid>jackson-databind</artifactid> <version>2.4.1.1</version> </dependency> <dependency> <groupid>org.codehaus.jackson</groupid> <artifactid>jackson-core-asl</artifactid> <version>1.9.13</version> </dependency> <dependency> <groupid>org.codehaus.jackson</groupid> <artifactid>jackson-mapper-asl</artifactid> <version>1.9.13</version> </dependency> </dependencies> companiesrestcontroller.java
@requestmapping(value = "/companies", method = requestmethod.get) @responsebody public list<companies> listcompaniess() { return new java.util.arraylist<companies>(companiesservice.loadcompaniess()); } i added code snippet in applicationcontext.xml, described in : reference:
<bean class="org.springframework.web.servlet.mvc.annotation.annotationmethodhandleradapter"> <property name="messageconverters"> <util:list id="beanlist"> <ref bean="stringhttpmessageconverter"/> <ref bean="marshallinghttpmessageconverter"/> </util:list> </property </bean> <bean id="stringhttpmessageconverter" class="org.springframework.http.converter.stringhttpmessageconverter"/> <bean id="marshallinghttpmessageconverter" class="org.springframework.http.converter.xml.marshallinghttpmessageconverter"> <property name="marshaller" ref="castormarshaller" /> <property name="unmarshaller" ref="castormarshaller" /> </bean> but in vain, none of worked.
i'd thankfull suggestions.
ps: used scaffolding generate crud application.
-regards
actually, when edit companiesrestcontroller.java
@requestmapping(value = "/companies", method = requestmethod.get) @responsebody public string<companies> listcompaniess() { return new java.util.arraylist<companies>(companiesservice.loadcompaniess()).tostring(); } or
@requestmapping(value = "/companies", method = requestmethod.get,produces="application/json") public @responsebody object[] listcompaniess() { return new java.util.arraylist<companies>(companiesservice.loadcompaniess()).toarray(); } i no longer have 406error, array containing records have in database, array, not json...
i've tried make use if jsonobject, still have same issue, used scaffolding create spring mvc application, , convert maven project add jackson libraries , dependencies, when cenvert it, project collapses , throws following errors:

the producible media types of mapped request can configured spring's @requestmapping.
example : @requestmapping(value = "/list", method = requestmethod.get, produces = "application/json")
