RE: DataImportHandlerException for custom DIH Transformer

[Peter Sturge]

Hi,

This problem is usually because your custom Transformer is in the
solr/lib folder, when it needs to be in the webapps .war file (under
WEB-INF/lib of course).
Place your custom Transformer in a .jar in your .war and you should be
good to go.

Thanks,
Peter

Resurrecting an old thread.

I faced exact problem as Tommy and the jar was in {solr.home}/lib as Noble
had suggested.

My custom transformer overrides following method as per the specification of
Transformer class.

public Object transformRow(MapString, Object row, Context
context);

But, in the code (EntityProcessorWrapper.java), I see the following line.

  final Method meth = clazz.getMethod(TRANSFORM_ROW, Map.class);

This doesn't match the method signature in Transformer. I think this should
be

  final Method meth = clazz.getMethod(TRANSFORM_ROW, Map.class,
Context.class);

I have verified that adding a method transformRow(MapString, Object row)
works.

Am I missing something?

DataImportHandlerException for custom DIH Transformer

[Tommy Chheng]

 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(MapString, Object 
row, Context context)?
