Hello, I am trying to integrate Lingo3g with Solr. I have arrived at the error ClassNotFoundException error using Lingo3g (verison 1.12.0) with Solr 4.8.0. I located the guava-18.0.jar, which contains the com.google.common.base.MoreObjects class, and have tried putting it in multiple locations within our Solr deployment, but have had no luck in getting by the error. So far, I have tried:
1) Adding Class-Path: guava-18.0.jar to the manifest file in start.jar, solr.war and lingo3g-1.12.0.jar, with guava-18.0.jar copied to the same folder as each respective jar file. 2) Putting guava-18.0.jar in the contrib\clustering\lib folder with the other lingo3g jar files. 3) Putting guava-18.0.jar in the java jdk bin folder. The stack trace I get is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/google/common/base/MoreObjects at

Note that we had clustering working with the free version that comes packaged with Solr. Thanks in advance, Collin
