Hello,

I am trying to get and also upload images thru REST API and the gallery is standard location, i.e., /content/gallery/myhippoproject. 
The REST mount point is 'restapi' and the servlet context is 'site'. 

I can get an image stored there as abc.jpg as 
http://localhost:9080/site/binaries/content/gallery/myhippoproject/abc.jpg using a browser and there is no problem with the interactive
retrieval of image thru browser.

Now I want to get the same image using REST API. I have configured Java class org.hippoecm.hst.jaxrs.services.content.ImageSetContentResource in file spring-plain-rest-api.xml and the path in that class is "/hippogallery:imageset/". Therefore I constructed the REST URL http://localhost:9080/site/restapi/hippogallery:imageset/original and trying to get representation of original image from the imageset node, but I get the error:

[BaseImageSetContentResource.getImageResource:128] Failed to retrieve content bean. org.hippoecm.hst.content.beans.ObjectBeanManagerException: Cannot return bean of type 'interface org.hippoecm.hst.content.beans.standard.HippoGalleryImageSetBean'



The web service is hit and but the error seems to be due to incorrect URL - it appears that it cannot find the standard gallery folder location. 



Question1: 

Given my REST mount point 'restapi' and servlet context 'site', what is the correct REST URL for retrieving original image in an imageset content in standard location, /content/gallery/myhippoproject ? 




Question2: 

I also want to upload image from a file using REST API. Given my REST mount point 'restapi' and servlet context 'site', what is the correct REST URL for uploading the original image from a file abc.jpg, to an imageset content in standard location, /content/gallery/myhippoproject ? 





Thanking you in advance. 


Thanks and Regards,

Amal

siteContentBasePath of HstRequestContext is automatically set "content/documents/myhippoproject" rather than "content/gallery/myhippoproject". That seems to the root cause. 


How do we override this?

Hi Amal,

You can configure the content root of a site as part of the HST configuration model. See [1]. You can edit this configuration in a running system using the Hippo CMS Console [2].

Let me know if this solves your problem!

Cheers, Oscar

Hi Oscar,

Thanks for your suggestion. Based on your suggestion, I edited 
value of hst:content of /hst:hst/hst:sites/myhippoproject to /content/gallery/myhippoproject. With this, I get requestContext.getSiteContentBasePath()=content/gallery/myhippoproject and this is a step forward for me.

This also means that the content root folder is NOT the root case of the original problem, although initially I thought it was.

Now I get the following error message 

Failed to retrieve content bean. org.hippoecm.hst.content.beans.ObjectBeanManagerException: Cannot return bean of type 'interface org.hippoecm.hst.content.beans.standard.HippoGalleryImageSetBean'


and  my code in REST web service method is quite simple: 


@GET

@Path("/getImageset")  

public HippoGalleryImageSetRepresentation getImageSetResource2(@Context HttpServletRequest servletRequest,   @Context HttpServletResponse servletResponse, @Context UriInfo uriInfo) 

{

        return super.getImageSetResource(servletRequest, servletResponse, uriInfo); 

 }






The problems that I face:

1.  I am unable to retrieve the imageset data in standard imageset folder, content/gallery/myhippoproject,  thru this web service.  

2. My second objective is to upload image, into standard imageset folder content/gallery/myhippoproject, using standard REST web service method BaseImageSetContentResource.updateImageResourceContent(), but I get stuck because of mapping issues mentioned above.  

​I would appreciate any clue from you. ​



Thanks and Regards,
Amal

​It may be noted that my web service class extends ​
org.hippoecm.hst.jaxrs.services.content
​.​
BaseImageSetContentResource
​.

Hi Amal,

Let's first focus on retrieving the image set. As part of our test suite there is a running example of a REST API exposing both documents and imagesets. Have a look at [1], which is the tag of the test suite which was set when we released 10.2.0.

After you export, build (with -DskipTests or a lot of tests will fire) and run this, you will find near the bottom of the home page a few example links to specific variants of an imageset. Look for "Dummy example REST links". An example link:


A few notes:
  • You should not have to compose these links yourself if you are using the HST, these links are rendered in following file: resources/src/main/webapp/WEB-INF/jsp/components/main/home.jsp:40
  • The hst:link tag specifies the mount that should be used to render the link
  • In the console there are a few sub mounts under the /restapi mount

Hope this helps, Oscar

Hi Oscar,

Thank you very much. The issue has been resolved. 

The mistake that I had made was that I treated the REST Web Service as "plain". When I treated them as "content-aware", the issue was resolved.  I had to change the REST URL accordingly. 



Thanks and Regards,
Amal
