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.
