The "ExistXMLDatabaseAccess.java"
file was removed and replaced by ExistDbXmlStorageManager.

Right, we also changed names of properties which are responsible for DB 
configuration. I might have not updated LS Installation page, sorry.

Hmm, but I see you're using new, right "component.ls_storage.*" naming 
schema. But anyway ExistXMLDatabaseAccess is deprecated.

My LS configuration part is like:

-----------------------------------------------------------------------------------------
# ServiceEngine Type
service.ls.class_name=org.perfsonar.service.lookupService.xmlType.XmlTypeLSServiceEngine

# Accepted requests
service.ls.message_types=LSQueryRequest,LSRegisterRequest,LSDeregisterRequest

# Database username and password for ls_storage
component.ls_storage.db_uri=xmldb:exist://localhost:8680/exist/xmlrpc/db/ls
component.ls_storage.db_username=lookupservice
component.ls_storage.db_password=sonar
-----------------------------------------------------------------------------------------
(you also must set "service.r.type=ls")

and "component.ls_storage.db_access" isn't used any more. Now, the 
storage manager is loaded by components.properties file, which for LS 
should be like:

-----------------------------------------------------------------------------------------
# file contains components to load
config=org.perfsonar.commons.auxiliary.components.configuration.properties.PropertiesConfigurationComponent
logger=org.perfsonar.commons.auxiliary.components.logger.log4j.Log4jLoggerComponent
ls_storage=org.perfsonar.service.commons.storage.xmldb.exist.ExistDbXmlStorageManager
-----------------------------------------------------------------------------------------

You configure LS by setting these two files only and it should work well.

By the way, I am working on the new release of LS with MA registration 
and Jetty application server inside. It should be done in about 3 weeks.

So, I suppose you're able to run Exist's client.sh and log into the 
database?
