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(Map<String, 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(Map<String, Object> row) works. Am I missing something? --shashi 2010/2/8 Noble Paul നോബിള് नोब्ळ् <noble.p...@corp.aol.com> > On Mon, Feb 8, 2010 at 9:13 AM, Tommy Chheng <tommy.chh...@gmail.com> > wrote: > > I'm having trouble making a custom DIH transformer in solr 1.4. > > > > I compiled the "General TrimTransformer" into a jar.
