  1. POHow do I access a config file inside the jar?
    text
    copied!<p>I'm using <a href="http://flatpack.sourceforge.net/" rel="nofollow noreferrer">FlatPack</a> to parse and load data from flat files. This requires loading a config file that stores mappings of the columns of the flat file.</p> <p>I have a constant to define the location of the mapping file:</p> <pre><code>private static final String MAPPING_FILE = "src/com/company/config/Maping.pzmap.xml"; </code></pre> <p>I have a parse(File dataFile) method that actually does the parsing:</p> <pre><code>private void parse(File dataFile) throws FileNotFoundException, SQLException { Parser parser; log.info("Parsing " + dataFile.getName()); FileReader mappingFileReader = new FileReader(MAPPING_FILE); FileReader dataFileReader = new FileReader(dataFile); parser = DefaultParserFactory.getInstance().newFixedLengthParser(mappingFileReader, dataFileReader); parser.setHandlingShortLines(true); DataSet dataSet = parser.parse(); //process the data } </code></pre> <p>When I jar up everything and run it as a jar - it bombs out on <code>FileReader mappingFileReader = new FileReader(MAPPING_FILE);</code> with a <code>FileNotFoundException</code>. That file is inside the jar though.</p> <p>How do I get to it?</p> <p>I've looked at <a href="https://stackoverflow.com/questions/600146/run-exe-which-is-packaged-inside-jar">this question</a> and <a href="https://stackoverflow.com/questions/463972/creating-a-new-file-using-an-existing-file-within-a-jar">this question</a> about accessing files inside jars and they both recommend temporarily extracting the file. I don't want to do that though.</p>
