Subject: SPI class of type org.apache.lucene.codecs.Codec error
Hi,
We are working on a project which uses Lucene 4.2.1. Actually we are
facing
an error message "java.lang.
ExceptionInInitializerError". We are using Maven for assembling the
project
and we have a dependency between two projects. When we do the test
with eclipse it works fine. However, when we incorporate our jar in a
client
that is tested outside Eclipse we got the
java.lang.ExceptionInInitializerError.
We are doing workaround to overcome the issue since yesterday, we got
the
same issue with both versions of Lucene 4.2.0 and 4.2.1.
Have you ever experienced such an issue with maven? Are the newer
Lucene versions safer from such an issue?
Here is the rest of the message error
Caused by: java.lang.
IllegalArgumentException: A SPI class of type
org.apache.lucene.codecs.Codec with name 'Lucene42' does not exist.
You
need to add the corresponding JAR file supporting this SPI to your
classpath.The current classpath supports the following names.
Thank you a lot in advance for your support.
Best regards,
-

Re: SPI class of type org.apache.lucene.codecs.Codec error
Hi guys, Thank you both for the help. @Adriano: we have just tried the solution that worked for you without success. @Duke: we could see in the fat jar in the Meta-Inf/services folder that we have org.apache.lucene.codecs.Codec and in org/apache/lucene/codecs we have the Codec class. However, the lucene42 folder under codecs does not include a classe Lucene42 instead, we have Lucene42Codec.class, Lucene42Codec$1.class and Lucene42Codec$2.class. Is that normal as the error we got says "A SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene42' does not exist"? The issue does not occurs as far as we are within Eclipse.

First you need to check the fat jar file and the file META-INF/services/o.a.l.codecs.Codec and its counterparts are there. If no, then the workaround is to have way to add all META-INF/services/xxx into your fat jar. If yes, the problem may be with classloader, classloader can't locate the SPI file within its context, I guess it's not this case. Hope this help. Best regards, Duke If not now, when? If not me, who?

Re: SPI class of type org.apache.lucene.codecs.Codec error
Dear all, Please do you have any suggestion regarding the below issue? best regards, Gayo Hi, Thank you both for the help. Here are the contents you asked. For the final Jar that we use with a third client application: The content of META-INF/services/org.apache.lucene.codecs.Codec is org.apache.lucene.codecs.lucene40.Lucene40Codec org.apache.lucene.codecs.lucene3x.Lucene3xCodec org.apache.lucene.codecs.lucene41.Lucene41Codec org.apache.lucene.codecs.lucene42.Lucene42Codec The content of META-INF/services/org.apache.lucene.codecs.PostingsFormat is org.apache.lucene.codecs.lucene40.Lucene40PostingsFormat org.apache.lucene.codecs.lucene41.Lucene41PostingsFormat I do realize that there is no org.apache.lucene.codecs.lucene42.Lucene42PostingsFormat. Is that a possible reason for the issue? Please not that lucene is primarily used by a maven project on which depends our final project. The content of META-INF/services/org.apache.lucene.codecsbothPostingsFormat andCodec of that project are similar to those I listed above. The two POM are listed here: 1) http://lesimisped.free.fr/servo/pom1IMM.xml (it uses 3 lucene jar); 2) final: http://lesimisped.free.fr/servo/pom2Final.xml. In both POM we have changed the configuration of the transformer after a suggestion from this list. META-INF/services/org.apache.lucene.codecs.Codec I have also noticed that into the original lucene.core.jar, the /META-INF/services/o.p.l.c.PostingFormat content is org.apache.lucene.codecs.lucene40.Lucene40PostingsFormat org.apache.lucene.codecs.lucene41.Lucene41PostingsFormat there is no org.apache.lucene.codecs.lucene42.Lucene42PostingsFormat and in the repository /org/apache/lucene/codecs/lucene42/ of the jar there is nothing similari to Lucene42PostingsXXX.class (http://lesimisped.free.fr/servo/lucene42.png) contrary to /org/apache/lucene/codecs/lucene41/ for instance (http://lesimisped.free.fr/servo/lucene40.png).

Multilangual indexing (in the same index)
Hi, I wiss to index different set of multilingual documents in the same index. As each document may contains several languages (currently English and French) currently I'm using two Index (with the corresponding Analyzer for each part of the document). The search is performed in one of the index depending to the language specifyed in the Query. I wish to use a single index with two differents Fields, An English field and an French Field, both stemmed by the corresponding Ananlyzer. SO I need to instanciate two IndexWriter. Is'it possible to do that, as to create and a new Index we need to instaciate IndexWriter with the option true (lock) ?
