I think it would be cool if Lucene included a class that facilitated creating a RAMDirectory from an index in a JAR file, for the kind of point-and-click startup that Bill is talking about.

You'll have to implement org.apache.lucene.store.Directory to load the index from the JAR file. Take a look at FSDirectory and RAMDirectory for some more details.

How to add a Lucene index to a jar file?
Hi. I'd like to package up a Lucene index with the Lucene class files and my own application classes into a single jar file, so that it forms a "double-clickable" single-file Java application that supports searching over the index. However, I'm not sure how to read the index (create an IndexReader) if the files that form the index are packaged into the same jar file with the code. If anyone could shed some light on how to do this, I'd appreciate it. Thanks! Bill - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
