Hi,
I am trying to define a custom FieldType for SOLR 1.4.1.
To this end, I created the JAR file TestType.jar, I added a lib path in
solrconfig.xml so that this JAR file
as well as apache-solr-core-1.4.1.jar and lucene-core-2.9.3.jar are
included.
I then edited schema.xml and defined my new type:
<fieldType name="myloc" class="afg.TestType" sortMissingLast="true"
omitNorms="true"/>
Starting up SOLR, I see that my classes have been loaded successfully:
INFO: Adding

classloader

replaceClassLoader

But when schema.xml is processed, I get a load error. Now superclass
FieldType of TestType cannot be found.

Is this a known problem? What can I do to fix this?
