[opencms-dev] errors template3 demo after upgrade to opencms 8.5.2. (solved)

[Hein van der Kallen]

Hello list,
I upgraded a copy of an opencms 8.0.4 installation ( upgraded may times before) to opencms 8.5.2. 
After that I loaded the 19 modules that are not in in the upgrade but only in the standard opencms.war ( rename to .zip and unpack) 

load com.alkacon.opencms.v8.template3.demo.shared_8.5.2 to shared folder
load com.alkacon.opencms.v8.template3.demo_8.5.2 to /sites/default
load org.opencms.dev.demo_8.5.1 to /sites/default
org.opencms.welcome_8.5.2 to /sites/default
and others to /

The lists in the flower demo's did not work. I suspected because solr was not installed.
so I copied the solr directory from opencms.war to /WEB-INF/solr
copied the requesthandlers node to opencms-system.xml 
copied the solr node to opencms-search.xml ( enabled = "true") ( from the same file in opencms.war)
copied the documenttype node containerpage-solr to opencms-search.xml
copied the indexsource node solr_source to opencms-search.xml
copied the fieldconfiguration node solr_fields to opencms-search.xml
after that a restart of opencms still worked.
but when I 

copied the index nodes "Solr Online" and "Solr Offline" to opencms-search.xml

opencms does not start and the indexes are not created

I got 

22 Sep 2013 12:12:10,053 ERROR [ache.solr.common.SolrException: 176] Error in xpath:java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "org.apache.xpath.XPathContext$XPathExpressionContext.getVariableOrParam(Lorg/apache/xml/utils/QName;)Lorg/apache/xpath/objects/XObject;"

etc 

why could I not create a solr-index? 

I removed xalan.jar from the lib directory.

and then opencms started again and I could rebuild both indexes.

But still the liststs in flower demo give errors like 

Container-page element "/.content/list/l_00008.html" could not be rendered with formatter "/system/modules/com.alkacon.opencms.v8.list/formatters/side.jsp".
Collector "byQuery" was not found.Stack trace

add 

 <collector class="org.opencms.file.collectors.CmsSolrCollector" order="170"/>

to opencms-vfs.xml

and that worked too

And finally give flower_en directory the property locale=en

and the same for the welcome directory

Have fun..
