Community Server Shows Service Is Unvailable when Accessing Comments (Doc ID 2002569.1)

Last updated on JUNE 29, 2017

Applies to:

Oracle WebCenter Sites - Version 11.1.1.8.0 and later
Information in this document applies to any platform.

Symptoms

A web page was configured with WebCenter Sites|Community-Gadgets (CG) to display comments (or reviews, polls, ratings).

Instead of showing comments, the page shows "Service is unavailable".

The cg_production_node1.log file shows several exceptions when the page is loaded:
2015-04-21 11:24:40,596 [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] ERROR com.fatwire.wsdk.rest.WidgetCompilerResource - Failed to process request: skin/wsdk.comments.css
java.lang.NullPointerException
    at com.fatwire.cos.skin.CustomSkinManagerImpl.getCustomSkinHolder(CustomSkinManagerImpl.java:92)
...
2015-04-21 11:24:45,370 [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] ERROR com.fatwire.wsdk.rest.WidgetSDKResource - Failed to execute method feed in widget wsdk.comments

    at com.fatwire.wsdk.cos.records.commons.processor.LanguageProcessor.process(LanguageProcessor.java:27)
...

 

In the corresponding WebCenter Sites Delivery database, the cg_st_locator table has records for the site:

cg_st_locator table
cos_object_keycos_value_locators
settings.comments.site.MySite [{"id":1425546652401,"descUid":"schema::cos:comments-admin:appearance:existing_comments"},{"id":1425546652407,"descUid":"schema::cos:comments-admin:appearance:structure"}, ...]
settings.gadgets.dashboard.MySite [{"id":1425546652588,"descUid":"schema::gas:gadgets:dashboard:permission-properties:authorized_domain"}, ...]
settings.reviews.site.MySite [{"id":1425546652631,"descUid":"schema::cos:reviews-admin:appearance:review-type"}, ...]

settings.commons.MySite [{"id":1425546652891,"descUid":"schema::cos::commons:permissions:authorized_domain"}, ...]

but there are no records in the cg_st_value table for the ids listed in the cg_st_locator.cos_value_locators column.
