SolRJ 1.4 : java.lang.VerifyError: class org.apache.solr.search.SolrIndexReader
overrides final method setNorm.(ILjava/lang/String;B)V
Hi,
I'm starting using SolR 1.4 queried by SolRJ 1.4
(all official release that I've downloaded from the main link on the web
site :
http://www.apache.org/dyn/closer.cgi/lucene/solr/
mirror :
http://apache.multidist.com/lucene/solr/1.4.0/
downloaded the .zip file.)
The servers start OK
and the class CommonsHttpSolrServer works fine.
But when running the class EmbeddedSolrServer to do the same basic test,
it fails with the following "compilation like" exception :
09:55:59,859 INFO ~ Adding
'file:/C:/Projets_RD/WorkspacePlay/apache-solr-1.4.0/contrib/clustering/lib/jackson-mapper-asl-0.9.9-6.jar'
to classloader
09:55:59,859 INFO ~ Adding

Exception in thread "main" java.lang.VerifyError: class

at util.UtilSolR.getEmbeddedSolRServer(UtilSolR.java:65)
at util.UtilSolR.main(UtilSolR.java:29)
Am I doing something wrong ? I'm not a newby in Java and this exception
seems more like a compilation problem than a config or usage pbl.
In my classPath, I've imported the jars from the folder
"\apache-solr-1.4.0\dist".
The class SlorIndexReader extends the class FilterIndexReader. It
effectively overrides the following method :
*@Override
public void setNorm(int doc, String field, byte value) throws
StaleReaderException, CorruptIndexException, LockObtainFailedException,
IOException {
in.setNorm(doc, field, value);
}*
The ovrridden method seems to be in a "lucene" jar :
org.apache.lucene.index.FilterIndexReader or
org.apache.lucene.index.IndexReader
Does this pbl come from a build/packaging error, like a no compatibility
between jars that have been packaged together ??
I do not have the source code of the Lucene library... so I can't check
where the pbl exactly comes from...
Can someone help me please ??
I really don't know what to do to make that work...
I'm going to try to download from other mirrors, but I guess that obviously
they will provide me with the exact same package.
Thanks.
Damien

to keep a

share it for all requests.

...it's not a compilation error, it's a runtime incompatibility error:
essentially the bytecode you have for SolrIndexReader is not compatible
with the bytecode you have for something higher up in the class hierarchy
(ie: FilterIndexReader, or IndexReader) ... this can really only happen if
the source code for the child class (SolrIndexReader) wasn't compiled
against the same version of hte parent class that is being used at runtime
This problem tends to happen whne you've got multiple versions of a class
(one old, one current) in your classpath.
the fact that it works for you when you run solr in a servlet container,
but now when you run it embedded in your app suggests that you have an
older version of the Lucene jars somewhere in the class path for the app
you are trying to embed solr in.
