hi Uwe,
thank you for answering. I believe that this is the complete stack
trace, no (pasted again below)?
I'm actually not trying to do anything fancy with codecs etc. I'm
trying to do something very basic: create an object of type
indexWriterConfig. the CFML (Railo) code is as follows:
indexWriterConfig = createObject( "java",
"org.apache.lucene.index.IndexWriterConfig" ).init( Lucene.Version,
this.indexAnalyzer );
where Lucene.Version is an object of Lucene.VERSION_40 and
this.indexAnalyzer is an Analyzer object that I create before. one
possible problem is that Railo ships with a very old version of Lucene,
so I had to disable some of the jars that ship with Railo but I believe
that I removed all of them. I also had to disable a jar of
apache-commons-codec that ships with Railo to avoid version conflicts.
stacktrace below:

Hi,
can you give the *full* stack trace including nested Exceptions (root causes)?
There is also the problem, that the line numbers are not matching the ones from
Lucene 4.0 - so maybe you are using different JAR versions in your webapp? This
could be caused e.g. by an older lucene 4.0 JAR file together with codecs.jar
of a different version. Please make sure that all JAR files are next to each
other in the same classloader.
The problem here is *not* that the lucene-codecs.jar file is missing or the class was not
found. Ignoring the line numbers and looking at the "message" text, the problem
here is that the code was not able to create an instance of that class, but it already
found and loaded it. The problem here is that you did not post the nested Exception so
there is no chance to say, why calling the constructor failed. One reason may be a
security manager in your application server, preventing to init the class, but this
cannot be checked unless I have the full stack trace.
Does it work if you use standard codec? Why do you use appending? What happens
when yu use only lucene-core.jar and use the default codec only? If you don't
use appending codec then there is something really crazy with your setup and we
need, in any case, the full stack trace.

Subject: Cannot instantiate SPI class
I'm trying to access Lucene4 from Railo (an open-source application server)
when I try to create an IndexWriterConfig I get the error: Cannot
instantiate SPI class: org.apache.lucene.codecs.appending.AppendingCodec
any ideas?
TIA
