The CodecUtil.writeHeader signature has changed from public static DataOutput writeHeader(DataOutput out, String codec, int version)
in lucene 3.4 (which is the method not found) to public static void writeHeader(DataOutput out, String codec, int version) in lucene 4.0 It means that while you're using solr 4.0, some 3.4 jars are stuck somewhere in the java classpath. Obviously some code is looking for this 3.4 method. If you're using the start.jar executable, you should have a look at your system-wide classpath If you're using tomcat (and that sounds plausible in this situation), you should trash the "work" directory sub-folders of your tomcat installation; and restart it. Tomcat unpacks war archives in this directory, and it may have kept a 3.4 solr war deployed here. 2011/11/9 elisabeth benoit <elisaelisael...@gmail.com> > Hello, > > I've just installed Solr 4.0, and I am getting an error when indexing. > > *GRAVE: java.lang.NoSuchMethodError: > > org.apache.lucene.util.CodecUtil.writeHeader(Lorg/apache/lucene/store/DataOutput;Ljava/lang/String;I)Lorg/apache/lucene/store/DataOutput; > at org.apache.lucene.util.fst.FST.save(FST.java:311)*. > > Does anybody know what I've done wrong? > > Thanks, > Elisabeth >
