I'm having trouble making a custom DIH transformer in solr 1.4.
I compiled the "General TrimTransformer" into a jar. (just copy/paste
sample code from http://wiki.apache.org/solr/DIHCustomTransformer)
I placed the jar along with the dataimporthandler jar in solr/lib (same
directory as the jetty jar)
Then I added to my DIH data-config.xml file:
transformer="DateFormatTransformer, RegexTransformer,
com.chheng.dih.transformers.TrimTransformer"
Now I get this exception when I try running the import.
org.apache.solr.handler.dataimport.DataImportHandlerException:
java.lang.NoSuchMethodException:
com.chheng.dih.transformers.TrimTransformer.transformRow(java.util.Map)
at
org.apache.solr.handler.dataimport.EntityProcessorWrapper.loadTransformers(EntityProcessorWrapper.java:120)
I noticed the exception lists
TrimTransformer.transformRow(java.util.Map) but the abstract Transformer
class defines a two parameter method: transformRow(Map<String, Object>
row, Context context)?
