Further observation on the error: All requests to add documents through the /update URL land up with the same error, irrespective of the fields contained in the document. If I don't use the UIMAUpdateRequestProcessor, I can add/update documents successfully.
Here are the snippets relevant to updateRequestProcessor declarations in my solrconfig.xml <requestHandler name="/update" class="solr.XmlUpdateRequestHandler"> <lst name="defaults"> <str name="update.processor">uima</str> </lst> </requestHandler> <updateRequestProcessorChain name="uima"> <processor class="org.apache.solr.uima.processor.UIMAUpdateRequestProcessorFactory"> <lst name="uimaConfig"> <lst name="runtimeParameters"> </lst> <str name="analysisEngine">C:\ex1\RoomNumberAnnotator.xml</str> <bool name="ignoreErrors">false</bool> <lst name="analyzeFields"> <bool name="merge">false</bool> <arr name="fields"> <str>content</str> </arr> </lst> <lst name="fieldMappings"> <lst name="type"> <str name="name">org.apache.uima.tutorial.RoomNumber</str> <lst name="mapping"> <str name="feature">building</str> <str name="field">UIMAname</str> </lst> </lst> </lst> </lst> </processor> <processor class="solr.LogUpdateProcessorFactory" /> <processor class="solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> Please help.
