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.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

CommonsHttpSolrServer is thread-safe and if you are using the

to keep a
static instance of CommonsHttpSolrServer per solr server url and
share it for all requests.
