Hi,

it depends on your usecase, but it should work. I would suggest running through the basic hippo tutorials to get a feel of how Hippo works.

Dear Jasper,

Dear Jasper,

i am getting below ERROR, could you please help.

[][]org.hippoecm.hst.jaxrs.services.content.AbstractContentResource.[] - Failed to retrieve content bean. java.lang.NullPointerException

2014-10-14 19:24:34.104 ERROR [qtp66192343-19][][WebApplicationException]com.art.webapp.hippo.cms.rest.HippoContentRest.getHippoHtmlRepresentation[22] - java.lang.NullPointerException

[Jasper Floor]

Hi,

the configuration should go into a directory project/hst/src/main/resources/META-INF/hst-assembly/overrides/configuration.xml.

All I can say about that error is that it can't find the content bean. Perhaps you can set a breakpoint and figure out exactly what is being asked for and where exactly it is failing.

Dear Jasper,

do to delete and update folders in Hippo, i have to create bean. this beans represent as nodes in CMS ?

i want to know how i can create node as bean, could please let me know how to do this.

1) i have created one rest like below

@Path("/myhippoproject:testdoc/")

public class HippoContentRest extends AbstractContentResource  {

@RolesAllowed(value={"everybody"})

    @GET

    @Path("/")

    public HippoHtmlRepresentation getHippoHtmlRepresentation(

                      @Context HttpServletRequest servletRequest,

                      @Context HttpServletResponse servletResponse) throws ObjectBeanManagerException {

HstRequestContext requestContext = getRequestContext(servletRequest);

ContentRewriter contentRewriter = getContentRewriter();

getRequestContentBean(requestContext);

//HstRequestContext requestContext = RequestContextProvider

// HstRequestContext

return super.getHippoHtmlRepresentation(servletRequest, null, null);

    }

}

My hippo structure you can i find in attachment. how i can create content beans from that.

could you please let me know.

Hi,

a bean in this case is the jvm representation of a document. You have to create those in your java code  and they have to be linked to a node type in your cnd. If you are looking to create a document then you don't need to get the request content bean as there won't be one.

Hi,

you haven't irritated me. If I don't answer it's because I'm busy with other things. Please don't worry about that.

I'm not really sure exactly what it is you are asking now. You can take a look at the feeds project (https://forge.onehippo.org/gf/project/feeds/). This uses a rest pipeline, though for generating output.

So is it that you are reaching your rest service but don't know what to do from there?

Why do you want to delete/create via REST? Perhaps it is the right way for you or perhaps we can suggest another route. For now I understand you want to be able to manipulate the cms through REST. This is certainly possible.

this page
http://www.onehippo.org/library/concepts/rest/restful-jax-rs-component-support-in-hst-2.html

has some code which sort of outlines what you want. I'm not sure what to add to what is there already. Also take a look at the resource links at the bottom.

mvg,
Jasper

Thanks Jasper,

In my project jetty sever it's not identifying custom-jaxrs-resources.xml file, we have multiple modules of hippo.

inside content module i have created folder structure like META-INFO/hst-assembly/overrides/

please see the attachment for more info about modules.

but it is identifying hippoecm-extension.xml. 

the following content i added in that.

<?xml version="1.0" encoding="UTF-8"?>

Hi,

your file contains customRestContentResourceProviders node twice,

override folder should go into your site module and not in the content module, where it is located currently, 

hth
