[opencms-dev] Zero search results in image gallery when not accessed over site server

[Jan Michael Greiner]

Hello all,



I attached a debugger (Eclipse) to the remote Tomcat.

I set a breakpoint in org.opencms.ade.galleries.CmsGalleryService in the method public CmsGallerySearchBean getSearch(CmsGalleryDataBean data).

A difference I see between access to the image gallery over https://opencms_default:8443 and https://opencms_workplace:8443 in source code line 931, String gallery = data.getStartGallery();:


For https://opencms_workplace:8443 start gallery is null, for https://opencms_default:8443 it is set to /.galleries/office/.
Can this be the reason why the image gallery is empty, if I access it over https://opencms_workplace:8443?


Update: No, it seems the start gallery is just the gallery selected by default...



I will debug further, and I will keep you up to date with my findings :-)


Help is still appreciated... The source code is fine, well structured and so on. But it is really hard to dive into such a large project...



Best regards

Jan Michael Greiner

Dear all,


in my installation there is a problem with the image gallery, and I didn't find a similar case in the list archive.

I have three sites in opencms-system.xml

<sites>
   <workplace-server>https://opencms_workplace:8443</workplace-server>
   <default-uri>/sites/default/</default-uri>
   <shared-folder>/shared/</shared-folder>
   <site server="https://opencms_my-site:8443" uri="/sites/de.mysite/" title="My Site" position="50.0" webserver="false"/>
   <site server="https://opencms_default:8443" uri="/sites/default/" title="Demo Site" position="10.0" webserver="false">
      <parameters>
         <param name="locale.main">en</param>
         <param name="locale.secondary">de</param>
      </parameters>
   </site>
</sites>

The sites are accessed through a reverse proxy on another virtual machine. There is no difference with the image gallery, if I access the sites directly or through the reverse proxy.



In https://opencms_default:8443 the image gallery works as expected.But I get the message described in 

http://lists.opencms.org/pipermail/opencms-dev/2016q2/041124.html

"Accessing workplace or ADE through a server which has not been configured.
Your site configuration is probably incorrect."


In https://opencms_my-site:8443 I don't have a login yet, so I can not test the image gallery.


In https://opencms_workplace:8443 the image gallery has always 0 search results.



I don't think there is a problem with the search index, because the image gallery would not work in opencms_default in that case.
Anyway I rebuilt the search index several times, to be sure.

When restarting Tomcat there is an exception logged with SolrIndexWriter (two times, because there are online and offline search index?):

Can anybody help me with this?
