The other would be to : use a RAMDirectory and populate the directory with the index files, : perhaps reading the files using Class.getResourceAsStream or by creating : a JarInputStream from an URL to the application jar. : : You can easily get an InputStream to your own application jar like this: : : CodeSource cs = theClass.getProtectionDomain().getCodeSource(); : URL providerURL = cs.getLocation(); : InputStream is = providerURL.openStream(); : : Have fun, : --Jon : : : -----Original Message----- : From: Thomas Lepkowski [mailto:[EMAIL PROTECTED] : Sent: Monday, August 29, 2005 8:43 AM : To: java-user@lucene.apache.org : Subject: Index files in jar : : : Hello, : : I have a set of index files that I'd like to distribute with my Java : application.
