I haven't but I have an idea of how you would. What path did you give IndexSearcher? Did you use the IndexSearcher(String) constructor? I don't think there's any chance you could load an index from a JAR file out of the box. First a JAR file is zipped, secondly you'll look it up from the classpath rather than giving a file system path. I would guess you need to extend: org.apache.lucene.store.Directory and create a JARDirectory class, which can find the appropriate bits within the JAR for Lucene. First get the JAR file: ClassLoader.getSystemResourceAsStream(jarFilename) then use the java.util.jar.JarInputStream class to read it. One potential problem might be random access, since I think streams are sequentially accessed. If the index isn't too big you could have your JARDirectory class just wrap a RAMDirectory and just load the contents of the JAR into memory. -- Miles Barr <[EMAIL PROTECTED]> Runtime Collective Ltd. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
