java - How to build Parent and child relationship on JAXRS -

i'm having problem rest service. problem have relationship between entities , when entity going written json jboss can't that. here code:

child class:

  @xmlrootelement   class child implements serializable {     private static final long serialversionuid = -6058827989172575778l;     private string childname;     private parent parent;     public string getchildname() {       return childname;     }     public void setchildname(string childname) {       this.childname = childname;     }     public parent getparent() {       return parent;     }     public void setparent(parent parent) {       this.parent = parent;     }   } 

parent class:

  @xmlrootelement   class parent implements serializable {     private static final long serialversionuid = -8280071521315889541l;     private string parentname;     private list<child> childs = new arraylist<child>();      public string getparentname() {       return parentname;     }     public void setparentname(string parentname) {       this.parentname = parentname;     }     public list<child> getchilds() {       return childs;     }     public void setchilds(list<child> childs) {       this.childs = childs;     }   } 

rest method

  @get   @path("/test")   @produces("application/json")   public response test() {     final parent parent = new parent();     parent.setparentname("parent name");      child child = new child();     child.setchildname("child name");     child.setparent(parent);      parent.getchilds().add(child);     responsebuilder rb = response.ok(parent);     return rb.build();   } 

the jboss generates broken json:

{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent":{"parentname":"parent name","childs":[{"childname":"child name","parent": 

how can ignores "parent" field on child? there way without rewriting entities, such "custom writer" or that?

well, @damo helped me on right thing. using jboss i've looked api jboss uses internally work jax-rs.

i discovered jboss 7.1.1.final uses resteasy 2.3.2.final , because of that, uses internally jackson-jaxrs version 1.9.2.

by knowing this, imported libs provided on application , used @jsonignoreannotation because @xmltransient works when providing xml api ignores if generates json.

if use jboss 7.1.1.final , uses maven add dependency:

    <dependency>         <groupid>org.codehaus.jackson</groupid>         <artifactid>jackson-jaxrs</artifactid>         <version>1.9.2</version>         <scope>provided</scope>     </dependency>     <dependency>         <groupid>org.jboss.resteasy</groupid>         <artifactid>resteasy-jaxrs</artifactid>         <version>2.3.2.final</version>         <scope>provided</scope>     </dependency> 

the result of child class this:

@xmlrootelement @xmlaccessortype(xmlaccesstype.field) @xmltype(proporder = { "childname" }) class child implements serializable {   private static final long serialversionuid = -6058827989172575778l;   private string childname;   @xmltransient   @jsonignore   private parent parent;   public string getchildname() {     return childname;   }   public void setchildname(string childname) {     this.childname = childname;   }   public parent getparent() {     return parent;   }   public void setparent(parent parent) {     this.parent = parent;   } }
