migrating from solr 1.3 to 1.4

[Sachin Sebastian]

Hi there,

       I'm trying to migrate from solr 1.3 to solr 1.4 and I've few 
issues. Initially my localsolr was throwing NullPointer exception and I 
fixed it by changing type of lat and lng to 'tdouble'. But now I'm not 
able to update index. When I try to update index it throws out error 
saying -

Feb 12, 2010 2:14:11 PM 
org.apache.solr.update.processor.LogUpdateProcessor finish
INFO: {} 0 0
Feb 12, 2010 2:14:11 PM org.apache.solr.common.SolrException log
SEVERE: java.lang.NoSuchFieldError: log
at 
com.pjaol.search.solr.update.LocalUpdaterProcessor.processAdd(LocalUpdateProcessorFactory.java:138) 


I tried searching on net, but none of post regarding this issue is 
answered. Have anyone come across this issue?

Thanks,
Sachin.
