[OWASP-stinger] loadRuleset does not work with ear in wls

[Thomas Schmidt]

The loadRulesets(String path) method does not work for files in an ear that
runs in weblogic server:
**
     * Load any rulesets stored in SVDL files on the path. This method
stores the time each file was
     * modified in a hashmap, and reloads if any of the files were modified.
     *
     * @param path the path to the SVDL files
     */
    private void loadRuleSets(String path)....

The following code works:

/**
     * Load any rulesets stored in SVDL file-InputStream.
     *
     * @param svdlStream the InputStraem of a SVDL file
     */
    private void loadRuleSets(InputStream svdlStream)
    {
        Builder builder = new Builder();
        try {
            Document d = builder.build(svdlStream);
            rulesets.put(new Integer(1), parseRuleSet(d));
        } catch (Exception e) {            
            log.error(" > Error loading svdlStream -- skipping", e);
        }
    }

A new getInstance(InputStream svdlStream) method is necessary:

/**
	 * Returns the singleton instance
	 */
    public static Stinger getInstance(InputStream svdlStream) {
        if (instance == null) {
            instance = new Stinger();
        }
    instance.loadRuleSets(svdlStream);
    return instance;
    }

It would be called like this:

public void init(FilterConfig config) throws ServletException {
        this.config = config;
        try {
            InputStream svdlStream =
config.getServletContext().getResourceAsStream("/WEB-INF/rules/sample.svdl")
;
            stinger = Stinger.getInstance(svdlStream);
        } catch (Exception ex) {
            log.error("", ex);
        }
    }

Would it be posibble to have a similar getInstance(InputStream svdlStream)
method in a next release ?

Thanks Thomas
