    <p>I'm trying to create a json object from my hibernate entity using jackson which can be posted to a remote url using jersey. I can't seem to figure out how to convert my hibernate entity to a json object. Using resteasy-jackson I was able to create my own web service accessible by localhost which outputted my json object correctly within my screen, but I was hoping to build the json object without having to use a webservice to my own app. Perhaps I'm going about this all the wrong way? I just don't want to manually have to add every property to a json object. </p> <p>What I've tried thus far, </p> <p>interface</p> <pre><code>@Path("/company") public interface CompanyResource { @GET @Produces("application/json") public List&lt;Company&gt; getAllDomains(); @POST @Produces("application/json") public Response post(Company company); @GET @Path("{id}") @Produces("application/json") public Company getDomainObject(@PathParam("id") Integer id); } </code></pre> <p>class</p> <pre><code>public List&lt;Company&gt; getAllDomains() { return this.companyDAO.findAllCompanies(); } public Response post(Company company) { companyDAO.updateCompany(company); return Response.ok().build(); } public Company getDomainObject(@PathParam("id") Integer id) { Company domainObject = this.companyDAO.findCompanyById(id); if (domainObject == null) { throw new WebApplicationException(Response.Status.NOT_FOUND); } return domainObject; } </code></pre> <p>post service</p> <pre><code>public void setupRender() throws GeneralSecurityException, UnsupportedEncodingException { try { Client client = Client.create(); String url = kayakoWebService.generateURL(); WebResource webResource = client.resource(url); ClientResponse response = webResource.accept("application/json").get(ClientResponse.class); if (response.getStatus() != 200) { throw new RuntimeException("Failed : HTTP error code : " + response.getStatus()); } //Outputs object rather than json System.out.println("test " + companyResource.getDomainObject(1)); } catch (Exception e) { e.printStackTrace(); } } </code></pre> <p>Company.class</p> <pre><code>@Entity @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Company extends StatefulEntity { @Validate("maxLength=50,required") private String name; @Column(nullable = true) @Temporal(TemporalType.TIMESTAMP) private Date createDate; @Column(nullable = true) @Temporal(TemporalType.TIMESTAMP) private Date cancelDate; @Column(nullable = true) @Temporal(TemporalType.TIMESTAMP) private Date modifyDate; @ManyToOne @JoinColumn(name="parent_id") private Company parent; @Column(nullable = true, length = 5) private Integer roomUnitCount; @Column(nullable = false, length = 8) private String accountNumber; @JsonIgnore public String getAccountNumber() { return accountNumber; } public void setAccountNumber(String accountNumber) { this.accountNumber = accountNumber; } //additional getters setters } </code></pre> <p>cfg.xml</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"&gt; &lt;hibernate-configuration&gt; &lt;session-factory&gt; &lt;property name="hibernate.connection.datasource"&gt;jdbc/domain&lt;/property&gt; &lt;property name="hbm2ddl.auto"&gt;validate&lt;/property&gt; &lt;property name="hibernate.format_sql"&gt;false&lt;/property&gt; &lt;property name="hibernate.show_sql"&gt;false&lt;/property&gt; &lt;property name="hibernate.cache.use_second_level_cache"&gt;true&lt;/property&gt; &lt;property name="hibernate.cache.use_query_cache"&gt;true&lt;/property&gt; &lt;property name="hibernate.cache.region.factory_class"&gt;net.sf.ehcache.hibernate.EhCacheRegionFactory&lt;/property&gt; &lt;property name="hibernate.generate_statistics"&gt;true&lt;/property&gt; &lt;/session-factory&gt; &lt;/hibernate-configuration&gt; </code></pre>

    1. COIts not entirely clear what your problem is. Where is `companyResource` defined in your client? Are you trying to create a `Company` object on the client side and use it in a POST request to the server?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
