class周辺から、リソースを見つけるメソッド

たぶん、jarにも対応
PathnameUtilsに加えよう

	public File searchFileAroundClass(String fileName){
		ClassLoader loader=this.getClass().getClassLoader();
		String path=this.getClass().getName().replaceAll("\\.","/");
					path=path+".class";
		
		URL url=loader.getResource(path);
		String classPath=url.toString();
		System.out.println(classPath);
		if(classPath.startsWith("jar:")){
			int last=classPath.lastIndexOf("!");
			classPath=classPath.substring("jar:".length(),last);
		}
		System.out.println(classPath);
		if(classPath.startsWith("file:/")){
			File checkFile=new File(classPath.substring("file:/".length())).getParentFile();
			while(true){
				File tmp=new File(checkFile,fileName);
				System.out.println(tmp.getAbsolutePath());
				if(tmp.exists())
					return tmp;
				else{
					checkFile=checkFile.getParentFile();
					if(checkFile==null)
					break;
				}
			}
			return null;
		}else{
			return null;
		}
