.

ClassLoader loader = ClassLoader.getSystemClassLoader();

System.out.println(loader.getClass().getName());

InputStream in = null;
if (loader != null) {
URL url = ClassLoader.getSystemResource("com/comp/resource/workflow.properties");

String path = System.getProperty("catalina.home") + File.separator+ "workflow.properties";
System.out.println("Path"+path);
if (url == null) {
in = loader.getResourceAsStream("com/comp/resource/workflow.properties");

if (in != null) {
props = new Properties();
props.load(in);
System.out.println("property val :" + props.getProperty("PushAppImpl"));
}

}
if (url != null) {

in = url.openStream();
System.out.println("property val :" + props.getProperty("PushAppImpl"));
} else {
System.out.println("STILL NULL");
}

NO matter what it gives Back Null
the jat filwe is in the LIB directory why is it not able to locate the propertiers file?

Try using Properties prop =

Try using

Properties prop = new Properties();
String pwd = System.getProperty("user.dir");
prop.load(new FileInputStream(new File(pwd+"\\com\\comp\\resource\\workflow.properties")));

Play around with the path, you'll figure it out...

Class Loader issue

Rather than using ClassLoader.getClassloader(), user this.getClass().getClassLoader() to load a resource.

It seems you are trying to

It seems you are trying to load properties file, the best way to load a properties file is to use 'ResourceBundle' class from java.util.* package.

e.g
ResourceBundle rb = ResourceBundle.getBundle("com.comp.resource.workflow");

/*get the value for the key*/
rb.getObject(keyProperty)

Not necessarily

ResourceBundles have two advantages: They are implicitly locale-aware and they can (using ListResourceBundle) be classes providing non-text resources. However, if you read the file often then a ResourceBundle approach will be costly since it will try multiple varieties of locale-infixed names like "workflow_en_US.properties" etc. before using the fallback non-decorated name.

Properties file loading issue

I have put myconfig.properties file under classes folder as ./classes/myconfig.properties while the code to load this file is under ./classes/com/example/TestLoader. I try to load this file as props.load(TestLoader.class.getClassLoader().getResourceAsStream(PROPS_FILE)); but somehow its not loading the file.

Thanks for sharing this

Thanks for sharing this information. I found it very informative as I have been researching a lot lately on practical matters such as you talk about...

not reloading new values in web app

Hi, I have used this with dynamic property loading sample in my application but not work .its not showing new values being modified in Jboss/tomcat.Please help me.

Hi, I have used, Properties

Hi,
I have used,
Properties prop = new Properties();
prop.load(new FileInputStream(new File("sample.properties")));
and placed the "sample.properties" in Tomcat's "bin" folder. It worked.

I find that going with the (via FileInputStream, FileReader, and

I find that going with the (via FileInputStream, FileReader, and RandomAccessFile) route is the simplest and usually one of the most effective.

Best Strategy Indeed!

thanks for sharing the best strategy for loading property and configuration files in Java.

Good

Thanks ,excellent presentaion of very important details

瞳の黄金比率に東亜燃料工業が村内の焼内湾にある技手久島に石油備蓄基地引越し業者を計画したレディースファッションに端を発し、反対派コンタクトレンズ 大分の招きによって、当時鹿児島県看板列島諏訪之瀬島にコミューンを築いていたクレジットカード 現金化である山田塊也らが宇検村に移住し、反対運動を展開した。その後、1984年10月には建設計画は撤回されたが、入植者グループは村内の久志集落に定住し、コミューンを「無我ブラジャー道場」と名付け共同生活を営んでいた。1987年頃から入植者グループの子供達が地元の小学校に登校することを止めたことなどから地元住民とのコールセンターが悪化しはじめ、村議をはじめとする村の有力者によって「村民会」が電話工事された。

1988年8月に東京の右翼団体松魂塾の代表者が無我利道場の母屋の所有権を車買取し、街宣車で入植者グループの早漏を図り始めた。早漏松魂塾の構成員がダンプカーで無我利道場に高輪 歯科し母屋を破壊、入植者1名に重傷を負わせる。

1989年9月「道場」の共同生活は解散し、各みなとみらい レストランでの生活を始めたが、その後も追放運動が続けられ たため、リサイクルトナー年7月には入植者グループが追放派の住民に損害看板 ワールドシートを求める訴えを提起した。一方、1991年11月には追放派の住民らが「平穏に生活する権利を侵害されている」として入植者グループに損害賠償を求める訴えを提起した。1993年11月17日、鹿児島地方裁判所名瀬引越しにおいて入植者グループと地元住民との和解が成立し、入植者グループが地元社会との相互理解に努力すること、地元住民が追放運動を停止することなどが合意された。

さほど多くもない村民が「入植者グループ」「追放派」「追放運動拒否派」に分かれ、また右翼団体や人権運動家らの島外者も入り乱れ、村内に大きなオーエスを残した赤ちゃんモデルである。事件を取材したノンフィクション看板 ワールドシートに 「楽園」がある。

A new set of extensions to the properties syntax

Properties have not really been updated since Java 1.0. A new open source project is filling the gap - with variable substitution, inclusion, lists, nesting, etc. Have a look at http://code.google.com/p/eproperties/
